lets get back shall we we are not talking car engines here or upping the compression on a car engine we are talking normal heavy diesel engines at their proper compression ratio. Please stay on track here.
I know you like to hear yourself but please other people here are actually interested in this technology even if you are not.
Brentanna:
mental midget we are not talking changing car engines we are talking heavy truck engines there is a slight difference.
What’s the difference if we’re going to use LPG to fuel a diesel compression ignition truck engine when the issue is the compression ratio being incorrect for the fuel type 
.
If you dont know the difference between a car engine and a heavy truck engine that explains why you have no clue what the hell you are talking about
Carryfast, I’m rapidly coming to the conclusion that you will never admit your error as shown by your failure to answer the question quoted below.
Failure to provide a straight answer will be taken as evidence that you really are a deaf & blind dinosoar.
“Stop sidestepping the question. We know already that we use the appropriate fuel in each type of engine because that works and has been known for years. The question is what happens if we do use the wrong fuel. You can call it any name you like, detonation, ignition, explosion, bang, pop, fizzle, I don’t care about the name you give to the reaction. All I want to know is, would anything at all happen to the petrol/air mix when used in an unmodified diesel engine? You seem to think there will be a reaction to the petrol/air mix being compressed even though there is no spark present.”

And if you can’t understand that the compression ratio of a truck diesel engine is’nt much,if any different,to a car diesel engine ?.
So carryfastthinkslow. I asked you earlier what is done to liquefy Natural Gas you haven’t answered me.

Diversion tactic noted.
Not LPG in any case, CNG or LNG. Methane in other words.

Please miss, please miss, ask me, I know…
They squish it until it goes all warm & runny. 
Edit, forgot the smiley and yes I do know the answer is BS.

you said earlier a gas engine now its changes to a car diesel engine, I am going to have to cut and paste this into office to show as an example of limited reasoning if I go back to teaching anytime.

ummm how many pints have you had ?

Not enough obviously!

Run an engine on petrol,at a diesel engine type compression ratio,and if/when the thing starts detonating it won’t matter wether there’s a spark or not.Which is why we use diesel fuel in diesel engines not petrol and it’s why petrol engines don’t run at diesel engine compression ratios.Is that answer clear enough.
I wonder why they have to store LNG in cyrogenic tanks…
and if/when the thing starts detonating
Please explain this part for me if / when

Not in the context of all my posts remember.In which I’m making the case that a spark ignition LPG fuelled engine would be the most practical idea here considering the existing availability of LPG here.
yup he doesnt even know what the topic is, no wonder he doesnt get it.

No, but I see an “if” has crept in to your reply. You stated many posts back that petrol would ignite before diesel in the same engine. You have beat all round the bushes trying to avoid admitting your error. I see that “if” in you reply as a slight and grudging acceptance that you may be wrong and everyone else was right. Give in yet?
LPG needs to be compressed to over 600lbs to auto ignite

Get it running first and then it would probably be a case of when not if.But to save the bother just do what I said to DD and ask a truck manufacturer here wether or not running a truck Diesel engine on LPG would invalidate the warranty and why.
