how does zetec works

[818juice]

what is zetec?
and how does it work?
and how is it different from vtech,
I also wanted to know is their a zetech controller like a
vtech selenoid control unit

Zetec is just a marketing scheme to sell there cars...People who know of VTEC think hey, if the word Zetec sounds like VTEC it must be like it! Wrong...there is nothing special, just a good old fashion engine.

[z33guy]

zetec is just an engine name. VTEC has spoiled the world

[Whymelaugh13]

Is zetec DOHC?

[Privatebigandrew]

i know it is in the ZX3 and the ZTS and the contour, but it may come in SOHC too.

ok, zetec and vetec are two different things. zetec isn't just a name ford slapped on its engines. yeah it sounds like vtec and is almost the same thing but it isnt. they both have to do with camshaft lift, duration and all of that good stuff. but ford's zetec has to do more with throttle position as to when the second set of camshaft lobes are engaged. vtec engages more-so on speed and rpm.

Zetec is just the name of a engine FAMILY. There are 1.8L, 2.0L etc. The next gen. are the Duratec family.

VTEC is how Honda controls their cam lift and duration on some of their engines. VTEC stands for Variable Valve Timing and Lift Electronic Control.


Zetec has absolutly nothing to do with cams and does nothing but denote which family of engine is in the car. ALL Zetecs are double overhead cam engines, NO SOHC.
The Zetec name is no different than the Fe engine family or the Winsor engine family, it's just a name.

Read the name pal.

I hope you don't actually own one. The only Focus with variable cam anything would be the SVT, and that is on the intake only. Care to guess why that is???? It would have more to do with emissions than HP. It allows the SVT to get away from the close coupled cats found on the standard car.

[moparkilla]

what did you design? the sun visors? no kidding the svt is the one with variable cam timing. who honestly cares about zx3's or zts's, they arent worth much of anything. so go to a ford dealership, ask them for their little info sheet and it will say, "Variable Cam Timing" on it. wow. so quit talking out your ass, I don't really care who you are. take the time and learn something about engines.

[fordesigner]

Do you even own one???
I have a ZX3. I wouldn't purchase a SVT. Why pay for the same basic car and rip everything out to make a track car??
A ZX3 with simple and logical bolt ons can easily trash a SVT. Been done many, many times. SVT is nice to have some extra power and keep your warrenty.
Suspensions - Much better aftermarket.
Engines - ZX3 isn't encumbered with the VCT(worthless) or the dual intake manifold, making it far easier to tune.

You'll also notice that the RS does not use the VCT system, it uses the standard Zetec motor as it's base.

I've been a chassis designer for 20 years, I also worked for advanced engine on the mod motors. My name is on the Lincoln LS, Jag S-Type, T-Bird, Mustang and Cobra. Just to name a few. And you??????

Ok genius, tell us all why the VCT system is only on one cam. I've personally delt with Ford Engine on this issue, and know why. But please enlighten the rest of us.... What's the real reason and the funtioning behind it.

You also might want to inform everyone what a 1.6L Zetec, 1.8L Zetec and what a Zetec-SE is. Since Zetec doesn't refer to a family of engines and just the engine in the SVT.

Oh, by the way, you ARE aware that the Escort ZX2 also had the 2.0L Zetec WITH VCT.

Feel free to look any of these up.

As an ex-honda lover, it kinda appals me that most people cant spell V-Tec. V-Tec is simply having adjustable cam timing regulated by a solenoid connected to the ECU that at a certain RPM will adjust your cam timing. Variable Cam timing isnt worthless, and its amazing how I read a post containing the words SVT and think what a ricer. Also whats your name, I would like to look you up as being a chasis designer, what plant did you work for? What plant developed the 4.6L over the 5 first? When you come in claming youev been a professional for 20 years, you better make damn sure you ahev credentials to back it up. And what adult would make such hostile posts over absolutely nothing? Have some class.

[moparkilla]

whatever, im just a nobody, i dont know anything. hell, i dont even know what a car is. so you think what you want, and i'll think what i want. i have replied too many times already to your "logical" posts. so you go "design" some fords mr. designer. im out of here
