diesel will not burn hotter ....in fact it doesnt burn at all ....it works off combustion to ignite ....adding it will lubricate and clean but other than that it does nothing .....in fact it makes a slower burn with gas .... i have done this alot .... so lets think about this ...allthough its a small amount of acetone its an faster burning fuel(flash piont) so my piont is that it will clean but its buring properties are arguable.. lets disscuss.....hey i may be wrong and ill admit that but im useing my common sence <img src="/forums/images/graemlins/cheers.gif" alt="" />

Diesel doesn't burn???

deisel is non volitle ....its on burns while under conbustion.....try puttin a lighter up to it ....it will light if you have anought heat but its a non volitle fuel ...that means it wont combust on its own

I think he is talking about the diesel cycle. Diesel is not ignited by a spark, the high compression and temperature already in the cylinder ignites the diesel as it is being injected. The ultimate in detonation you could say. Adding diesel fuel to gasoline will still burn, but not in the manner that the engine is designed for.

Volatile means "Evaporating readily at normal temperatures and pressures" Non-Volatile idicates that it doesn not evaporate at normal temperatures and pressures. This does mean alot in a system that requires the fuel to atomize then vaporize in order to get into contact fully with the oxygen around it.

you said it better than me ....thank you sunder once again .... but yes thats the point i was trying to make <img src="/forums/images/graemlins/cheers.gif" alt="" />

Getting back to the acetone discussion . . . I see what you're saying somewhat, Sunder: gasoline blends with lower octane ratings can allow fuel-air mixture to combust during compression prior to the spark plug ignition in lower compression engines. But I am sticking to the concept that the energy release during combustion/oxidation can be called an explosion; it's these hot gases that result from the destruction of these moderately long carbon molecules that drive the piston back out of the combustion chamber.

Well, stuff happens, I get to drive the YJ about 100 miles tomorrow so it may not take as long as I thought to get some results with it. Stay tuned! <img src="/forums/images/graemlins/cheers.gif" alt="" />

Fred Friday evening a grandson and a friend went to a pile of scrap lumber to set it on fire... One of them poured 4 gals of gasoline into the pile. It was a very still evening with NO WIND! Not even a whisper.. When my grandson struck a match there was a huge explosion... Fire lept 60 feet in the air and lumbar parts flew up with it.. My grandson has 2ed burns over 20% of his body from this he will have a complete recovery we are told..
My point in telling this story is that although there was NOISE and FLAME Sunder would say that it was not an explosion.. In truth it was the same as inside of a cylinder. EXPANSION of the burning fuel is what caused the seeming explosion..
I guess a true explosion would be when a container has so much internal pressure that it is torn to pieces by the pressure ie BOMBS or firecrackers..
But like you I do not know another word that would suffice for what it is that happens in there.

I think our definition of explosion is what is at fault.

From what i have been taught, an explosion is the rapid combustion of everything in a medium at once.

Normal engine operation does not fit my definition of an explosion. In normal engine operation, the spark plug lights the AFM(Air Fuel Mixture), and the AFM burns in an even outward pattern from the spark plug. This takes about .003 seconds on average.

Now if we follow my definition of an explosion, rapid takes on the discerning fashion. If you consider .1 seconds to be rapid, the AFM is indeed exploding. If you start working as an electrical engineer in the .000000001 second intervals, you'd say .003 seconds is an eternity. So really, it depends on what you define as your time constants. Since the flame goes from one side to another in a linear "domino" fashion, and it is not and instantaneous process, I see normal engine running as nonexplosive rapid burning of the AFM.
