*ahem*... please :(

ahem.. help, or do for you? What do you need these definitions for, and how detailed/complete are you looking to have them? I could probably define about 90% of that off the top of my head, but I'm not about to type all that out without GOOD reason.

if you don't want to .. you don't have to.. of course

i want them for my site supercarstats.com, and a lot of them i don't know myself:(

...... only a paragraph or less....as little as possible i guess, but for the important ones like torque and hp, well..long

175¿ so far....

This sounds like fun!
I will copy an dpaste the answers to all the ones I can get IF you give me credit on your website, and i can make suggestions for your site!
I await your reply.

:)

of COURSE you will get credit -- at the bottom in size 10 font or something like

Horsepower is a hummer thingy with thingie thingies in the thingy thingy thingy and so it goes good. Contributed by: Chris

where chris would be your email address or website

Uh, my website sucks.
my email is [email protected]
I started last night, and I have added stuff, and done alot (already about 2 hours worth!)

I give you about 10 or so..


-Concept Car: Any car that has been through the design process that has not yet been slected for production. It may be for show only and never intended for production or it may be a revised edition of a current model.

-Convertible: A vehicle (Usually a car) which has a retractable roof. This may be in the form of cloth or a more rigid material (Such as Fiberglass). The roof is usually stored within the rear of the vehicle and most convertibles have HARDTOPS, which are fixed roofs which can be put on the car as a substitute for a normal roof.

-Cruise Control: A device that is usally a standard feature on modern cars the allows the driver to designate a certain spped at which the vehilce is to travel at. This speed can be changed with acceleration and allows the driver to take his (her) foot off of the accelerater when driving. *Note cruise control is mostly for long trips so that the driver does not have to keep on the gas the whole length of the trip.

-Displacement: The volume within an engine the the cylinders stroke displaces. Can be measured using fluid or gas. The larger cylinder size, the larger the displacement.

-Drag: The force that acts upon any vehicle in motion and consists of wind resistance that resists the car's motion. Ex. Trucks create larger amounts of drag due to their box-like shape and large size.

-Drag Coeffecient: The measure of drag a vehicle produces. Is measured using a wind tunnel.

I'll try to help you every once in a while and you should check with others to confirm my definitions.

In drag it should be air, not wind resistance. Also your displacement is weird. I'm sure you understand it. Look at it this way: Measure the volume of a cyliner with the piston all the way down (end of power stroke). Then multiply that by the number of cylinder!
PS, I have worked some more, I might finish fhbhfghaergaefgkajdvhldahglalrgfd.
Sound good?

fhbhfghaergaefgkajdvhldahglalrgfd

??
thanx TONS guys... it'll still take me a long time w/ all those definitions, and i have even thought of more, but those will wait.....

it'll take for ever to recheck all defenitions, check 4 spelling errors, link them w/ other defenitions, etc., etc., etc.. might take about 4 weeks... but w/ a bit of help {THANX TONS} i might get it in 2 !!!!

Chris... where are the definitions??




thanx again

I've done about half, will finish (hopefully) in 48 hours. I have some spare time now.

thanx thanx thanx thanx... even on the front page of the definitions, I will put :

contributors: and then a list of ya'll...

and even a link saying thanks to the ppl @ AF

Here's a little help:

ZR-Rated - tires rated for use at up to 200 mph +
(for comparison sake, H-rated are good for 130 mph, V-rated are good for 149 mph, Z-rated are good for 149 mph +)

Gearbox - synonym for transmission

Now some of these are very basic, in fact flat out obvious. Come on, Brakes, Bumper, Exhaust Pipe, etc. You have to try a little harder to get your own definitions than that.

I've done it!!! Here it goes (some may not be intiterely (sp) correct)
I will add more when I write them for myself.


HERE THEY ARE!!!

-4WD: Four Wheel Drive
Power is directed to all four wheels. There are many types of 4WD, but when 4WD is used it
usually means the power is directed to all the wheels all the time, with open or limited slips
on each end. A true 4WD has locked differentials besides the locked center differential. This
way, 25% of the power goes to each wheel.
-A-pillar
Most cars have three pillars. The one where the windshield rises up is the A-pillar. It is at
the front of the car.
-ABS: Anti-Lock Brake System
A hydraulic servo applies brake pressure many times a second, usually about 80 times a
second. This gives you greater control, and it lowers stopping distances on wet and dry
pavement. People argue about how well it works on ice and gravel, but it gives you better
control.
-Aerodynamics
Basically, how well the car goes through the air. ‘‘Better Aerodynamics’’ can mean it goes
through the air better or generates more downforce. The world-record for a car is 0.16Cd. A
truck gives more than .5Cd. A Porsche 911 Turbo GT2 makes .34Cd. Usually, sports cars
give of a good Cd for downforce.
-Air Bag
A bag in the car that inflates when you get in an accident. It works by sensors telling when
you get in a crash. This causes a pellet Sodium Azide decomposes to produce Sodium,
Nitrogen gas, and heat. 100g of Sodium Azide makes 60 litres of Nitrogen. This causes the
bag to inflate in 1 tenth of a second. The bag also has some iron[III] oxide, which reacts
with the sodium to make harmless sodium oxide and iron. Airbags will save your life if you
wear your seatbelt.
-Air Conditioning
A device that produces a lot of cold air, keeping you cool. They suck horsepower, lowers
fuel economy, and increases weight.-Air Dam
At the front of the car, it hangs down below the bumper. It is there for looks and better
aerodynamics (by forcing air around the car rather than under it, where it can be snagged,
and cause lift.)
-Air Vent
Any vent that lets air in or out.
-All Wheel Drive: See AWD
-Alternator
It generates power to recharge the battery, run accessories, and operates the sparkplugs. It
is a magnet connected to a wheel which is driven by the fan belt. The magnet is surrounded
by copper wire, which generates power.
-Anti-Freeze
Used as engine coolant. It is anti-freeze because water freezes in the winter, and has a
lower heat capacity.
-Anti-Lock Brake System: See ABS
-Automatic Transmission
A transmission that shifts by itself with no driver involvement. When the gas is pressed
hard, it creates a vacuum, telling the transmisssion to downshift. If the throttle is floored, ti
will wait for the redline to shift. If the throttle is applied lightly, it will shift at low rpm’’s to
reduce noise and improve fuel economy. And Everything in between.
-Automotive Shows
Car manufactures or private individuals show their cars to the public.
-AWD: All Wheel Drive
-Axle
Connects the wheels to the car. There are many types of axles, but they are all round,
connect to the wheels and somewhere on the body.
-B-pillar
The pillar between the front side windows and rear side windows. Some cars lack a B-Pillar
as a styling exercise.
-Base Price
The price of a car without any options; the lowest price for a car.
-BHP:
Brake Horse Power, that is the power the engine produces. A brake is connected a shaft
coming from the crankshaft. This measures torque. Horsepower is derived from torque. The
formula is (Torque*rpm)/5252. As a result, below 5252 rpm, torque is higher than hp, and
after 5252 rpm, horsepower is higher.
-BHP / Liter
The amount of power per liter of displacement. Hp/displacement (in liters)
-Blower: See Supercharger
-Boot
An english way of saying the trunk. The back of the car where you put groceries, luggage,
dead people, etc.
-Bore
The diameter of the cylinder or piston.
-Brake Horse Power: See BHP
-Brakes
Used to stop the car. 2 types are used today, drum and disc
-Brake Pads
With disc brakes, the part that touches the brake rotors and piece of metal attached to the
turning part of the axle connected to the wheel. When the brakes are applied, the rotors go
in, and the pads (attached to the rotor) hit the metal, turning kinetic energy into heat
energy.
-Brake Shoes
Pieces of abrasive material that get pushed into the inside wall of drum brakes.
-Bucket Seats
Seats in a car that only allow one person to occupy them. More sporty than bench seats,
they hold you better and give (arguably) better comfort.
-Bumper
The farthest extremity forward and behind the car. In North America, they must stand
5mph impacts and not cause damage to the rest of the car.
-C-pillar
In all cars, and many SUV’’s and Wagons, it is the last pillar (between the rear window and
rear side windows.)
-Camshaft
It is connected to the crank by a chain, pulley, or gears. It operates the valves, the loves
hitting either pushrods (in a OHV engine) or hit one of several types of devises, pushing
down on the valves (in SOHC or DOHC engine.) The cam has lobes on it, which are like
weird shaped donut (with no hole), which affects how long the valves stay open, and how
far down the valves go.
-Carburetor
Most modern cars do not use a carburetor. They mix gas and air together, then let it go into
the engine.
-Carbon Fiber
Simply, carbon is heated then threaded together, making an exceptionally strong and light
material. It is also very expensive. Used on very good cars.
-Catalytic Converter
It is part of the exhaust system. What is does is change Nitrous Oxides (bad), unburned
hydrocarbons (bad) and several other nasty stuff into harmless carbon dioxide. Almost.
Carbon Dioxide causes global warming, so it is just the lesser of evils.
-Chassis
The basis of the car. It is what the car is made on.
-Clutch
It connects the engine to the transmission. When engaged, it connects the two. When you
press in the clutch, it dis-engages the engine from the transmission, allowing you to change
gears with blowing anything up.
-Concept Car
A car created by a manufacturer. Usually just a wild idea, but sometimes they show what
type of styling or features new cars will have.
-Convertible
A car that can remove its roof, sometimes at the touch of a button, sometimes it requires a
lengthy stop to remove the top. These cars weigh more than a closed-top car, and have less
rigidity (their body’’s flex more, the car shakes on rough stuff.)
-Coolant: See Engine Coolant
-Cooling System
How the engines coolant is moved through the engine.
-Coupe
A type of car which has two doors. Not a hatchback. Usually sporty cars. Must have a back
seat.-Combustion System
How the engine makes power. Is it a rotary or piston engine (maybe even a turbine).
-Compression Ratio
The ratio of space left in the cylinder at top dead center as opposed to the space in the
cylinder when the piston is at the lowest point. Example: If a cylinder has a capacity of 500
cc’’s when the piston is at its lowest point (end of power stroke), and 50 cc when the piston
is a top dead center, then it is 500:50, or 10:1. The higher compression, the more stress is
placed on the cylinder wall and head, but the higher the power.
-Crankshaft
The ‘‘heart’’ of the engine. It is a piece of metal that the connecting rods connect to
(besides the piston)
-Cross-Drilled Discs
Disc brakes that have holes or slats in the face of the disc, to improve cooling (less fade).
Plus they look really neat.
-Cruise Control
A device that maintains a set speed
-Curb Weight
How much the vehicle weighs with a full tank of gas.
-Cylinder
The part of the engine that contains the explosion of gas and air.
-Defroster
A setting on the temperature controls. It directs air to the front window, heating it up and
removing ice and snow.
-De-Icer
On the rear window, it is a series of wires that heat up as power is passed through them,
melting ice and snow on the rear window.
-Differential
There are 3 types: Open, Limited-slip, and Locking. Some are computer-controlled (or
manually), and can change settings, which adds great confusion to which is which. Open
sends the power to the wheel with the least resistance, which is bad. Most cars come with
this. Limited Slip rear ends send power to the wheel with grip, which is good. Also called
viscous traction. Locking differentials send equal power to each wheel. Can be good or bad
(good off road, can be bad on road)
-Displacement
How much space the inside of the cylinders would take up if all the pistons were as low as
they could be (end of power stroke.)
-DOHC: Double OverHead Cam
There are two cams over each bank of cylinders. Usually makes the engine high-strung (it
revs very high, makes not much torque, but lots of horsepower.)
-Downforce
The amount of air pressure pushing the car towards the ground, expressed as pounds.
-Drag
How well (or badly) a car goes through the air. Measuered in Cd (next point)
-Drag Coeffectient (Cd)
How well the car goes through the air. The Porsche 911 Turbo has a Cd of .34, the lowest
drag car (GM EV1) is .19. A truck is more than .5, at least.
-Drive Ratio
See Final Drive Ratio.
-Drum Brakes
Brakes that keep the part used to stop it in the device. They are inferior to disk brakes.
-Dry Weight
The weight of a car when there is no fuel or occupants -- the weight of a car when it is
empty.
-Electrical System
The cars electrical system, how the power is routed from the battery and alternator to
sparkplugs, accessories, and so on.
-Electro-Hydraulic
When you tell the car to do something, the info goes through a wire, to a hydraulic servo,
which operates the system.
-Emergency Brake
It is usually the long handle in the center console, but it can be located elsewhere. It applies
the rear brakes with maximum pressure. If this is done while driving, when you steer the
back end will slide around, and you will get tons of oversteer. It is usually used when you
are parked to prevent the car from moving, especially in manual transmission cars. It is
used often by rally cars to lock up the rear wheels, allowing sharper turns. If you try this,
be careful, it is wild!
-Engine
Duh, the part (usually in front) that drives the car. If you didn’’t know that, you are stupid!
-Engine Configuration
How the cylinders are set up. They can be in a line, in a V, in a W (for lack of a better
letter), flat (H).
-Engine Coolant
The stuff used to cool the engine. Usually anti-freeze, but water can be used. Oil can also
be included, as it dissipates heat aswell.
-Environmental Protection Agency: See EPA
-EPA:
Environmental Protection Agency, it is a watchdog on all industry, tries to help the
environment.
-EPA City / Highway mileage
The EPA tests cars and tells us their mileage in city driving and highway driving. They are
usually a little optimistic, although calm (boring) driving can cause higher numbers for you.
-Exhaust Pipe
Where the exhaust goes from the engine. The pipe leads away, then lets the gas out into
the air.
-Exotic Car
This has no definition, but is best described as a rare, fast, luxurious (not always, and its
relative),very good looking, something special.
-F1-Style Transmission
You hit a paddle, and the transmission upshifts or downshifts, depending on which pedal
you hit or how you hit it. It has a hydraulic clutch, and operates very fast. In F1 cars, it can
shift in 0.015 seconds, faster than any driver. The Ferrari 360 does it in under 0.5 seconds.
On most road cars it can be switched to automatic, and it will shift by itself.
-F1-Style Paddles
Paddles on the steering wheel, when flicked they cause the transmission to change.
-Fairing
Any stressed part.
-Fan Belt
It is connected to the crankshaft, and operates lots of stuff, like the cam, distributor, Air
Conditioning compressor, power steering, alternator, etc.
-Final Drive
The gearing at the differential
-Final Drive Ratio
The total gearing (Final Drive ratio * gear ratio)
-Flat-#
A type of engine configuration in which the <cylinders> are arranged flat (horizontal to
each other.)
-Fog Lights
Lights mounted low down in the cars front, to help you see the road in bad weather.
-Four Wheel Drive: See 4WD
-Front Wheel Drive: See FWD
-Fuel
The stuff you put in your car. Can be gasoline, hydrogen, propane, methane, Compressed
Natural Gas, etc.
-Fuel Injection
Gas is sprayed into the intake plenium. There it is atomized as it goes to the cylinder. This
makes more power, cleaner emissions and better gas mileage than a carburetor.
-FWD: Front Wheel Drive
-G’’s, lateral acceleration
A unit of measurement used to describe the amount of gravity. For example, on earth we
feel 1 G, but when doing special maneuvors (or turning the car steeply) we can feel several
more or less. Commonly used with <lateral acceleration>
-Gear Ratios
The ratio of the number of turns of the driveshaft (connected to the crankshaft) as opposed to the
number of turns the shaft sticking out the other end of the gearbox is moving. Usually top gear is
.9 or so (for each revolution of the crankshaft, the shaft sticking out the back of the gearbox is
moving 1.11 times.) First gear is is much lower (numerically higher), say 4.5. (It takes 4.5 turns
of the crankshaft to move the shaft on the other side of the gearbox to move 1 time.)
-Gearbox
The mechanical device which houses the drive gears. People usually use this as the transmission,
which is incorrect but commonly acceptable.
-Global Positioning System: See GPS
-GPS:
Global Positioning System. It uses 24 satellites orbiting the earth to find your location. It is
accurate to a few meters in civilian use. It works by tri-angulation; 3 or more satellites
(whose position is know) find out how far away you are from them. A computer then figures
out where you are. By taking several readings, it can tell your speed, direction, etc. Many
navigation systems use this by having maps that know where on the map your GPS position
is. This is what allows them to give you turn-by-turn directions to where you are going.
-Guage
Anything with numbers on it that tells you how something is working.
-Hatchback
A type of car whose trunk includes the rear window. Usually a two door. Sometimes hard to
differentiate from a wagon.
-Heat
It keeps you warm! Usually created by engine coolant (which gets warm quickly) being run
through thin pieces of metal, heating them up. Air is blown over the metal, getting heated,
and then blown to you.
-Hood
The part of the car that covers the engine or luggage (if the car is mid or rear engined)
-Horn
It makes a noise to warn other people you are there and to show that them what you think
of their driving ability. Also useful in movies, when the car gets in an accident, the horn
goes off forever.
-Horsepower
A measurement of an engines ability. The formula to find horsepower is torque times rpm
divided by 5250. The higher the horsepower, usually the faster the car.
-Hot Rod
No real definition, but any car that has been modified to be cool or special or fast, or
whatever.
-Hub Cap
A cover that goes over the wheel. Usually because it looks nicer than the wheel, or to resist
corrosion.
-HUD [Heads Up Display]
It displays information on the windshield, like speed, rpm’’s, etc.
-Hybrid
A car that uses 2 or more power sources. Usually a gas-electric. (Usually) The electric motor
assists acceleration, where most fuel and pollutants are used/created. It is usually
recharged by the gas motor when not in use. It is also recharged from the brakes. This
results in much lower gas consumption and fewer pollutants.
-Ignition
It is what starts the engine. Your key goes into the ignition, you turn, the ignition closes a
circuit, and the car starts. Can also refer to the whole starting procedure (starter motor,
electircal system, etc.)
-Ignition Switch
Where you put your key.
-Instrument Panel
In the car, the part in front of the car that contains most of the instruments (speedometer,
HVAC controls, radio, etc.)
-Intake Manifold
It usually sits on top of the engine. It lets the air (and eventually the gas, except in GDI
engines) into the cylinder.
-Integral Hydraulic Damper (Steering)
Makes it easier to steer.
-Jack
A tool that is used to lift up part of the car to repair something. It can be operated alone.
-Kevlar
A type of plastic. When layered, it is the primary ingredient in bullet proof vests. It is very
flexible, and cannot be stressed. In cars it is used to keep various things safe. Not used
very often, as it isn’’t useful in many circumstances.
-Lateral Acceleration
How well the car holds to the ground, measured in <g's>.
-Longitudinal Powertrain Layout
The engine is arranged north-south. The crankshaft faces the front of the car and the
interior.
-Lubricating System
A name for how the cars moving bits are lubricated. The engine uses oil, the transmission
uses oil aswell. All parts use oil, but different kinds.
-Manual Transmission

Anti-roll bar: also anti-sway bar. A piece of metal that connects the wheels on the front or rear of the car. Its main function is to keep both wheels rolling at the same rate when meeting bumps; but it also affects handling. A front anti-roll bar increases understeer and a rear bar increases oversteer. The thicker the bar, the better it works, and it works better at higher speeds. Another function is to keep the vehicle level in cornering.

Tire Speed Ratings: The maximum speed a tire can go safely. It determines your vehicles speed limiter's speed cut-off. Q = 99mph R = 106mph S = 112mph T = 118mph U = 124mph H = 130mph V = 149 mph W = 168mph Y = 186mph

Speed Limiter: A device that makes sure your vehicle cannot go over a certain speed. A ‘hard' limiter will disengage the throttle momentarily. A ‘soft' limiter won't let the engine rev over a certain amount, thereby keeping the speed down.

Tire Ratings: There are 3 ways these are set up, and here are some examples: 255/45HR-17, 255/45HR-17 89H, 255/45R-17 89H. The first number is the width of the tire in millimetres. 255 is large, 205 is the norm for many cars. The second number is the profile of a tire. It is a percentage of the width of the tire. In this case the tire is 114.75 millimetres high from the rim to the edge of the tire. Generally, a profile of 50 or lower is a ‘performance' tire. This is not always the case. Now it gets dicey. The R is always there. If it is the only letter, you will have to locate a number with the speed-rating letter next to it. That will tell you the speed rating. If there are two letters, the non-R letter is the speed rating. Bear in mind that if there is only the R, the speed rating can be hard to find. The number connected by a hyphen is the diameter of the wheel rim. M+S on the tire means it is all season. This can be deceiving, as it can mean almost-performance or almost-winter. Winter tires are good in snow,ice, etc, but awful in the dry (especially cornering). Performance tires are great in the dry, but really, really bad (and dangerous) in the snow, ice etc, but good on the rain, if its warm.

Variable-Valve Timing: When the valves can change their lift and endurance of lift, and when they are operated. Some cars use two cam lobes, a torque-boosting one for low rpm's, and a high-lift, long duration setup for high rpm's. The cams themselves can also shift longitudinally and horizontally, depending on engine speed. Some systems have only a few settings (usually when 2 cam lobes are involved) or be truly variable, constantly shifting. Variable valve timing improves performance and fuel economy.

Wing: A device placed on the rear of a car that goes up into undisturbed air. It can be in the shape of an upside-down airplane wing, or angled forward and down. This causes downforce, but increases drag.

Navigation System: A device that tells you how to get from point A to point B. Can and usually does incorporate GPS, to give you turn by turn directions. If not, you input where you are and it tells you how to get to where you want to go.

Wishbone: In a suspension, it is an A shaped piece of metal that works with various shocks and other dampeners to let the wheels move up and down. A wishbone suspension usually gives better handling, a better, more comfortable, more refined ride. It can be costly and take up a lot of space.

Strut: Used (mostly) in the suspension. It incorporates a coil spring with a shock absorber. Usually not as good as a wishbone suspension, but BMW uses struts to great success.

Torque Converter: A device on automatic-transmission equipped cars. It is between the engine and the transmission. It usually contains a viscous fluid. When the crankshaft spins, it spins a turbine or something similar at one end. This causes the fluid to move, moving a similar turbine at the other end, coupling the engine with the transmission. It is shaped in a circle with an indent in the middle, causing me to call them donuts. This device increases torque, but lowers horsepower and fuel economy. This is also why in an automatic, when you floor it, the rpm's go crazy, but you get no forward motion. Some torque converters now partially or fully lock to prevent this slippage.

Manumatic: A type of transmission that behaves like an automatic but if you choose, it lets you decide when it should shift. Not nearly as good as a manual, as the transmission usually shift anyway.

5-point safety harness: A really good seatbelt. It has 5 points (buckles or metal pieces). Usually, a belt goes across your lap, one between your legs, one over each shoulder (sometimes criss-crossing.) Used in race cars or extreme road cars.

HANS: Head And Neck Safety system (or close to that).A safety device used in racing. It is piece of carbon-fiber or other material that goes over your shoulders underneath your safety harness. It has straps on the back that attach to the back of your helmet. When you get in an accident, this prevents whiplash, and also increases your chance of survival greatly.

Monocoque: A cars chassis and integral body parts are all in one. This is good for ride comfort and refinement. It is not good for towing (it will distort and be ruined, same thing for a small crash, meaning non-life threatening.)

Body-on Frame: When a cars body is placed on a separate frame, usually two rails connected by cross-members to add structural rigidity.

IRL: Indy Racing League. In the United States. They are 3.5 liter normally aspirated cars limited to 10500rpm. They develop about 650hp. They only race on ovals.

CART: An international racing series that uses 2.65 liter turbocharged (4.95psi) engines with no rpm limits (usually about 16000 rpm is the norm)that make about 900-1000hp. They use racing slicks, race on ovals and road courses.

Wastegate: A device used with an engine that has forced induction. When the pressure on the intake goes over a certain level, it opens, allowing air to escape, lowering the pressure. Without this there is a very real chance the engine will break.

Subvented Lease
A subvented lease is a lease offered by manufacturers with special incentives to make it more attractive. Special incentives often take the form of a lower base interest rate, higher residual values, and manufacturer discounts. In many cases, a subvented lease will have a lower net interest rate than other leases. Subvented leases are usually only available for a limited time and the terms are not negotiable. Any negotiated change in the terms will result in a different net interest rate. Please note that subvented leases will not always be advertised. Also known as a subsidized lease.
Spoiler:
An aerodynamic aid used to decrease drag and increase downforce. It is a small ‘lip' on the back of the car.
Shock Absorber:
A device that either has gas, oil or something else in one end. When you go over a bump or put a load on it, it compresses, forcing the gas together or the oil into a reservoir. It can also be used to support parts

Flywheel
A heavy , toothed wheel mounted to the rear of the crankshaft that smooths out the separate power surges imparted to the crankshaft as each cylinder fires by resisting the tendency of the engine to speed up at the start of the power stroke and to slow down toward the end. It also serves as part of the clutch by transmitting power to the gearbox in a car with manual transmission, acts as a vibration damper and balance member for the crankshaft, and engages the teeth of the starter motor when the engine is cranked. Without it, the engine would shake itself to pieces, as well as ruining many other things.

A driving technique where the driver places the left side or the toes of his right foot on the brake pedal and the right side or the heels of his right foot on the throttle pedal so that he can simultaneously brake and throttle for a downshift. This is done to lessen the strain on the gearbox and drivetrain and makes for smoother driving.
Hydraulic
Any operation that uses the incompressibility of liquids, usually oil or water (because they cannot be compressed), and their ability to offer resistance when being forced into a small cylinder, thus transmitting an increase in applied force. Hydraulic brakes and clutches work on this principle. This makes it much easier to use things, and lets you do things you couldn't do otherwise.
Hydraulic Valve LifterA lifter that by means of hydraulic oil pressure maintains zero valve clearance (no clearance between metal parts) so that valve noise is reduced.
Headers
Special exhaust manifolds that replace the stock manifold. They are designed with smooth flowing lines to prevent back pressure caused by sharp bends, rough castings, etc., thus improving power and fuel economy. However, they are loud.
Caliper
That part of a disc-brake assembly hat straddles the discs and contains the cylinders, pistons and brake pads. When the brakes are applied, brake fluid flows to the cylinders in the caliper and pushes the pistons out, forcing the pads against the disc. Also, an adjustable measuring tool for determining the diameter of a shaft, cylinder bore, etc. by contact and retaining the dimension for measurement or comparison.
Camber

Clutch Disc
The rotating circular metal plate splined to the transmission input shaft: it has friction material on each face. The disc is located between the flywheel and the clutch pressure plate and is clamped tightly between these two members when the clutch is engaged, thus transmitting power from the flywheel through the clutch and into the gearbox.
Combustion Chamber
The space at the top of the cylinder, in the head and/or piston top, remaining above the piston when it is at top dead center. Combustion of the fuel-air mixture begins here.
Combustion Ignition

In the diesel engine (after Rudolf Diesel, the inventor) air is drawn into the cylinder and compressed to a temperature sufficiently high that fuel oil injected at the end of the compression stroke burns in the cylinder without a spark to initiate combustion.
Compression Ring
A piston ring at the top of the piston, forming a seal with the cylinder wall to prevent compression loss or gas blowby. Compression rings also help transfer heat from the piston into the cylinder walls and thus to the water jacket surrounding the cylinder.
Compression Stroke
Second stroke of the four-stroke cycle, in which the piston moves upward from bottom dead center, compressing the fuel-air mixture.
Condenser
A device for changing vapor into liquid, as in an air conditioning system. Applied to an electric circuit, a device (also called a capacitor) for temporarily collecting and storing a surge of electrical current for later discharge. In a car's ignition system the condenser is connected across the contact points to reduce arcing by providing a storage place for electricity as the points open. Constant-Mesh Gearbox

Brake Lines
The tubes or hoses connecting the master cylinder to the wheel cylinders in a hydraulic brake system.
Bypass Filter
A type of filter in which only some of the oil from the oil pump flows through the filter, the remainder bypassing the filter in its way to various engine parts.
Base Interest Rate
This represents the interest paid on the usage of the vehicle during a lease. It is the 'cost' of a lease before factoring in discounts, fees, and penalties and is not directly comparable to the APR for a loan. Lowering the base interest rate is one of the methods manufacturers use to subsidize leases. The phrase 'money factor' measures the same cost and can be converted into a base interest rate. For example, to convert a money factor of 0.00276 into an approximate base interest rate would multiply the money factor by 24. The result would be 0.0662 or 6.6%. Bounce (Valve)
It indicates a condition where the valve is not held tightly closed in the seat even though the camshaft has not opened it. Also called "flutter." or "float".
Ball Joint
A flexible joint using a ball and socket type of construction, used in steering linkage setups, steering knuckle pivot supports, etc. Their flexibility helps to compensate for the changes in the wheel and steering when turning or hitting a bump on the road. There are usually upper and lower ball joints attached to the upper and lower A-arms.
Net Capitalized Cost
This is the price of the vehicle after deducting any dealer participation, manufacturer discounts, and cap cost reduction ('down' payment) from the MSRP.
Net Interest Rate

Diameter of a circle within which a car can be turned around.
Turning Radius
Diameter of a circle within which a car can be turned around.
Two Plus Two (2+2)
Bodystyle incorporating two front seats plus two very small seats at the rear for children, small pets or extra luggage.
Thermal Reactor
A high-volume thermally isolated chamber replacing the exhaust manifold and providing a place for high-temperature afterburning of exhaust pollutants.
Thrust Bearing
A bearing with flanges on its two sides that prevents a shaft such as the crankshaft from moving endwise. Tie Rod
In the steering system, the rods that link the pitman arm and the idler arm to the steering knuckle arms. Timing
Refers to the crankshaft angles at which the valves and ignition points open and close.
Torsion Bar
A long straight bar fastened to the frame at one end and to a suspension part at the other.
Throttle Body
A housing containing a valve to regulate the airflow through the intake manifold. The throttle-body is usually located between the air cleaner and the intake plenum.
Transaxle
A drive setup in which the transmission gearbox, clutch, final drive, and differential are combined into a single unit connected directly to the driveshaft. It is used mostly in rear-engine cars.
Toe-In
An adjustment of the front wheels where the distance from the center of the left wheel to the center of the right wheel is less at the front of the wheels than at the back of the wheels. A slight amount of toe-in is usually specified to keep the front wheels running parallel on the road by offsetting other forces that tend to spread the wheels apart. The major force is the backward thrust of the road against the tire tread while the vehicle is moving forward. Other factors include play in the tie-rod assembly and allowance for angular changes caused by wheel bounce or variations in road conditions. Toe-in is measured in fractions of an inch or millimeters.
Roll Bar
A hoop of tubular steel installed behind the driver and extending above his head and across the car. The rollbar helps protect the driver from injury if the car rolls over.
Roll Cage
A tubular steel structure incorporating a rollbar plus additional bars along the doors, windshield header, roof rails, etc., built into some racing cars to help protect the driver if the car rolls over, is impacted by another car or crashes.
Rack & Pinion Steering
Steering system having a pinion gear on the end of the steering shaft that mates with a rack. When the steering wheel is turned, the pinion turns, moving the rack to the left or right. This movement is carried through tie rods to the steering arms at the wheels.
Refrigerant
The substance used in an air-conditioning system that absorbs and gives up heat as it changes from a liquid to a gas to a liquid.
Rocker Arm
A lever located on a fulcrum or shaft, one end on the valve stem and the other either on the push rod or directly on the camshaft lobes. As the camshaft rotates, the arms rock on their fulcrums causing the valves to open and
Road Holding
The ability of a vehicle to grip the pavement.
Rotor
A small rotating cap-like unit at the end of the distributor shaft. It is located on the breaker cam inside the cap. It connects between the center electrode and the various outer spark plug terminals as it turns, thus distributing the high voltage from the ignition coil secondary winding to the proper spark plug.
Radiator
A device that cools the liquid in the cooling system by allowing it to circulate through a series of water channels, which are exposed to air ducts.
Rotary Engine
An internal combustion engine which is not of a reciprocating (piston) engine design. There is no true crankshaft, although the power-take-off shaft is sometimes called the crankshaft. It is stationary or fixed in that it simply spins in place. The central rotor turns in one direction only and yet produces the required intake, compression, firing and exhaust strokes. Because it uses rotary motion instead of reciprocating motion, the rotary engine has better balance and less vibration than piston engines. Two common rotary engines are the gas turbine and the Wankel.

AHHH!! stop!!1


thanx I mean, but that'll take me FOREVER to put up.. I am STILL working on your other ones... expect the whole thing to up in a MONTH now!!



;)


but seriously, please wait a bit for more definitions

























i'll have the biggest dictionary ever!

I am still getting some more. That should be the bulk of it, though.
And I am also daunted with putting them on my web-page. I put them all on, not spaced or puncuated at all! It is quite a mess!

ok... just copy and paste my code when I put it on my site.. in better format, revised, spelling errors gone, and all done 4 u

thanks. I am still working on more

Do you have them up yet?? ;)

Wowee! I'm terribly impressed with you guys! Let us know when they're up! Keep it going!

You an extroadinarily diligent young man. Glad to have you as a member here with that kind of effort. I'm also giving you a "license to flame" next time you get pissed off in a post, and no mod will step in to steal your thunder. :ylsuper Hard work like that has its priviledges. Let her rip!!

LOL JD, "License to Flame". :D

Tire Speed Ratings: The maximum speed a tire can go safely. It determines your vehicles speed limiter's speed cut-off. Q = 99mph R = 106mph S = 112mph T = 118mph U = 124mph H = 130mph V = 149 mph W = 168mph Y = 186mph

where's Z rated??

Z = 200+

Z is actually 149+mph, which could mean 150 or 250 mph. You have to check elsewhere on the tire for the maximum speed rating. I'm not sure what is there if it is over 186mph (never seen a tire like that)

I'm also giving you a "license to flame" next time you get pissed off in a post, and no mod will step in to steal your thunder. Hard work like that has its priviledges. Let her rip!!
Can I be a moderator?? Please??
