 Subject: wtf propane injection? what/how/why
IP: Logged
Message:
I was on dragtrucks.com last night looking at trucks and I came across a 2000 powerstroke f-350 turbo deisel ford running 13's in the quarter. one of his mods was propane injection. I have never heard of propane injection before. does it benifit all cars or just diesel engines? any bad affects? can it be abused?
all help appreciated.

I think this is a diesel only mod, it kinda acts like nitrous for a diesel, only its not a catalyst, its a combustable fuel, and can be far more dangerous then Nitrous, Nitrous will not burn, but propain will, I hear its far easier to destroy an engine with propane. I'd be scared to death to try that on a gas engine, altho, I have heard of propane injection kits for exhause, makes some nice flames out the back!

VIPER 6 you are correct, propane is like "nitrous" for a desiel.Gas engines can be adapted to run on just propane instead of gasoline, as many taxi's are in large cities. They run very clean vertually no tailpipe emissions, but lack some power compared to gas engines.

I'm wondering that two I have been looking around the net and have found a couple kits for propane but it's mainly for a full conversion.
I still don't see why it wouldn't work on a gas engine if it works on a diesel, all the diesel kits I've seen are dry. I may just fill this nitrous bottle up and try it out.(doubtful)
why would propane be a catalyst for diesel and not gas? I like the idea of propane being combustable it will just add to the combustion already going on.

Diesel engines rely on "spark knock" to ignite the diesel fuel. The compression is so high in a diesel engine that the air heats up enough to ignite the fuel.
Propane would effectively lower the "octane" (how slowly the fuel burns)rating of the diesel (diesel is actually rated on a cetane rating, how quickly it burns).
This would result in the propane igniting earlier than the diesel, then it would be used to ignite the diesel fuel, earlier.
Propane also burns "hotter" than diesel or gasoline. Engines with a propane conversion kit should register higher on the temp gauge than those on gasoline.
That's how propane would act as a catalyst in a diesel engine.

We have a guy that shows up at the drags here and he runs an econo-rail on propane only. Turns in the eights- and that's bracket racing. Claims he only tears the motor down once a year. Beats the heck out of a nitro motor.

Propane is a excellant fuel,we used to do alot of conversions here until the price kept going up and made it less worthwhile,its works well with deisels in more power and cleaner engine and better mileage and as for fogging a gas engine I dont know never even thought about it :) and I would not try it on mine.When you do a conversion on a gas engine that was specifically built for propane it is a awsome engine,remember propane is 110 octane so 12-1 pistons is no problem,the power loss that people say is because the engine is never tuned for the propane,it likes alot of advance

don't you also get some kind of tax break running a truck on propane? thought I read that somewhere.
anyway I wanted to use propane like a booster system instead of just straight propane injection.

Porpane is sometimes used as an fuel additive with higher output NOX systems..
If you build a strong enough engine it will stay together at WOT, continue spraying more NOX and soon either the fuel pump can't provide enough gas, or the engine comes apart. If the engine did not come apart a solution is to add a propane system, the benifit is higher octane fuel is added to the mix.. more power is now available in the fuel/NOX/air mixture being pumped through the intake side... eventually the engine will come apart again, then back to the drawing board.

If I remember correctly, I have read somewhere that propane is equal to something like 115octane gasoline.
a few months ago on "2 guys garage"(new shadetree mechanic) they did a bunch of mods to a ram and one of them was propane injection and it boosted the HP something like 100hp. by the end of their mods it was around 450hp.

propane burns hotter, faster and cleaner than gas. propane will only 'work' with diesel, remember that diesel's octane rating is around 42. what do we use? 87-103. there is your answer. to get it to work to the best ability with the least damage would take extensive tuning in our gas engines. stick with nitrous if you must inject stuff.

als sorta right...i drove a zamboni for 2 years. there are some zams that run on propane for emissions reasons (propane burns very clean for a combustible fuel), others ran on huge batteries, others had a large power cable from the ceiling, (until a few drivers started getting strangled by the cable) the rest are driven by a regular engine. i loved telling people it was a blown 396 when they asked. its really a 1600 cc vw motor...the thing had dana 60's fr/rr with 5.83 and 5.86 gears, though. thats not a joke. and a hydraulically actuated trans and transfer case. ours was governed to 7mph LOL

Nitrous is not fuel or a replacemet for fuel "gas"..
NOX/NOS is really N2O, ( 2 parts Nitrogen and 1 part Oxygen),when heated to 570 degrees or higher it splits into Nitrogen and Oxygen... More Oxygen content than the basic air you breathe,(amount alos dependant on altitude). With more Oxygen available you need mix in more fuel to cause a bigger explosion which provides more power from your engine, if you can control it..
A side benifit from the nitrogen is that when it vaporizes it also has a cooling effect on the intake air. When you cool the air it becomes more dense adding even more air, which also contains oxygen,into the engines cylinder..

Back during high school my dad and many other guys had propane kits for their gas trucks.
The kit my dad had was for a 305 chevy they were for carbed engines. their was a switch and lever in the cab to switch from running on gas to propane. The engines got better gas mileage and hp, but it decreased engine life unless you had hardened pistons and stuff like that. I know the kit was fairly simple to install, you just had to hook up the stuff and adjust the carb to run on gas and propane.

There used to be a company in Norcross, Georgia that did fleet conversions to propane. Their name was Southern Cross, had a logo of the constellation.
I called some years ago to find out about it, around the time gas prices started climbing. At that time gas was around .75. Boy.
Anyways, the lady on the other end was quite rude. I asked about converting my car to 'propane' and she replied "You mean 'Compressed Natural Gas', don't you?" I said whatever and could not get a straight answer from her after that.

propane is a very clean fuel, but very dry. we have a van that runs on propane from the factory, it has 260 thousand k on it, and the cylinders seal better than new, the chambers were very clean. the problem is that there is no lubrication properties to propane, it destroyed the valve seats. if a motor is properly set up for propane it can make more power than gas ever could. the fuel has higher octane rating than gas, carries more btus of energy as well. propane slows the combustion of a diesel engine which is all right because the engine speed allows this to occur.

Propane can be used in gas. engine with no problem . You need a kit . In South America (Brazil)are common the cars and trucks have this kit . You can use gasoline and or propane (there are a switch ).But your engine will loose some hp (around 10%)but is totally free from emissions and your millage will increase a lot . It costs 1/3 less. Your car or truck will have to carrie a botlle (big engine = big botlle) virtually unbreakable.You have to refuel in a specific gas station (there are a specific nozzle).Itīs very cheap.

A propane engine need to be built properly before it is actually run on propance. They need a larger curve on the distributor and the valve seats need to be hardened. Stelite seats are recommended but expensive. If you don't use hardened seats and just convert it over to propane from gas you will pound out the valve seats within about 10 to 15000 kilometers thus causing a big problem.. you'll have to take the heads off and redo them anyway and propane really is'nt that cheap anymore. The biggest hassle is finding someone that can fuel you up. lance

A few years ago, i heard about a setup to allow you to use the natural gas of your house to refuel your vehicles. It cost around US$3500, though. The people that developed it suggested waiting for the price to come down for normal consumers.

A few days ago I saw a show on tv where a guy was putting on propane and NOS on a Ford deisel. Might have been the same truck as in the first post. Both systems he was installing were made by the company and were made to co-exist together. The show was "Trucks". Interesting

Okay, for the person that said nitrous doesn't burn and said propane is more dangerous than nitrous is wrong.Well, although nitrous doesn't burn it compresses the oxygen so much that it becomes unbelievebly flamable, and would be much more dangerous propane.

N20 is not flammable in any way no matter what you do to it. Even compressed to 3000 psi. It just adds 02 to the fuel mixture. The fuel is combustable not the N20.
Propane is highly dangerous. It is heavier than air and can leak and hide in low places waiting for a spark.
Oxygen is not explosive. But it raises the flash point of combustible materials to a very dangerous state.
Yes...I have installed Nitrous systems in hospitals all over the south east and have a license in natural gas and propane and explosive gasses.
