It would also run on gasoline. With the 360 engine with 8 to one compression, that got 12 MPG on gasoline, it only got 10 MPG on propane. With the 460 engine with 10.5 to one pistons, the mileage was the same with either gasoline or propane at 10 MPG. I couldn't tell much difference in power. Propane engines need at least 14 to one compression ratio. With a high compression ratio I believe the propane engine would put out more power than gasoline!
My neighbor was telling me that some guys were running diesel engines that ran on diesel and propane together. They supposedly were really putting out some power!
I now have that same carb on a little Subaru car!
Propane is used as an injectable enhancement on diesel engines in much the same way as nitrous oxide on a gas engine.[/quote]
Please go ahead and explain how nitrous alone adds power to a gasoline engine .
Adding LP to a diesel only works if there is enough unused O2 to allow complete combustion .
LP does not have a high enough octane to be operated in a Diesel engine with pilot injection at full power .
As soon as the amount of LP injected into the intake rises above the LEL . The engine will suffer from detonation .
A diesel will operate just fine on NG at
Full power when using a pilot ignition system . NG octane rating is much higher than LP .[/quote]
Well, first off - he said "nitrous oxide", and you re-named it as "nitrous"(I don't know what that is, but maybe you can explain what "nitrous" is to us).
Second, Nitrous Oxide (N2O) is a very strong oxidizer. Which means, it produces a lot of free O2 for added combustion of most carbon and hydrocarbon based fuels.
Third, when N2O is injected into any internal combustion engine, it is almost always combined with an added fuel injector to make up the correct stoichiometric ratio to burn inside the cyl.
I agree "nitrous" alone(whatever that is after you tell us) won't do anything without concomitant added fuel. Doesn't matter to me if one adds LP, gasoline, butane, diesel, kerosene, etc. BTW, N2O has been used in rocketry to increase the O2 content of the engine during the later phase of the burn where the inert N2 is a cooling agent for the manifold rings which tend to get darn hot and burn off.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
