Propane?

[Raz_Kaz]

How does this propane injection work and what are the pro's and con's of it?

[PunkAlex]

propane injection is used almost solely on diesel trucks...lots of time for a replacemetn of turbos or to help along iwht turbos. THe propane works to burn the diesel slower so it gets better power and less fuel unburnt...Ive never heard of it used on gasoline cars...i dotn think it would even work. Its for mainly heavyduty towing and trucking.

[flylwsi]

it can be used on ANY diesel engine, not just big trucks...
www.bullydog.com should have answers for you

Propane injection works on gasoline engines as well, although there is not a tremendous benefit. Remember that propane is injected as a gas, and at a very low temperature. It's also very high octane, around 110 IIRC, and is very useful as fuel enrichment for a high boost car, especially when the limits of the stock injectors have been reached.

Another good use is intercooler spraying, you spray into the intake side of the cooler, and you get a better temperature drop that way, as well as enriching the mix.

So from all of that, can anyone guess why cops use propane injection?

[flylwsi]

to increase power?

(where did you hear that cops use it?)

I was at a red light when a cruiser stopped beside me (it was a girl cop and was kinda hot so I was checkeing her out) Then I started to see this flammable sign on the car and it said "this car uses propane" or something along those lines. BTW I'm in Canada so it might be different in other areas?

Yea theres actually a dealership in my town that sells used cop cars but they remove a chip, which they sell seperately .....wouldn't mind having me a cop car

[Skyline_R32_Canada]

haha, ya i wouldnt mind the impala cop cars, they seem to be pretty nice rides

i saw an undercover impala cop car one day at night and i swear to god i thought it was a skyline (similar brake lights ) so i drove past him on the highway going 20 km/h faster than the limit and then i realized it was a cop when he tipped his hat at me! lol (didnt get a ticket thank god)

[Raz_Kaz]

Actually theres an impala in my town that did a skyline conversion to it. Looks so nice, but it doesnt perform like a skyline

PS that cop car couldnt do anything abuot you speeding by him other than give you a warning because he didnt have you taged with a radar gun nor were you in sight of his on dash camera. His word vs yours. Not worth th trouble for some cops but others are real pain!!!!

[flylwsi]

i doubt it's got a skyline conversion.
they've got stock tail light covers that look like skyline lights.

the car may have been powered by CNG, compressed natural gas, but i doubt it had propane injection.

That sticker means that the car has been converted to use propane as fuel, there are a lot of propane taxis here in Toronto.

Trust me, the back and front looks like a skyline. I don't know about the sides which I couldnt tell were a skylines or not. As far as the cop car goes, I'm 100% sure it said propane, next time I see a cop, imma take a pic and ask em

Its not propane injected, its propane fuel.
