Carryfast do you forget I do have an engineering degree.
surely the best idea is to run an electronic controlled diesel engine with two ECU maps,one for diesel and one for LPG,and just use LPG all the time wherever possible.
Bingo we have a winner
Brentanna:
Look at the temperatures, what temperature does diesel autoignite 410 degrees, if your engine has been warmed to operational temp you already have 195 degrees temperature in the engine at any given time. Compress the air mixture, electronically meter in you LP, at the proper time in the compression sequesnce inject your diesel. The compression has given you the 215 degree temp increase to ignite the diesel while still far beow the 1004 degrees needed for the LP gas. What temperature will the ignited diesel go to ? 1187 degrees 183 degrees over temp of autoignition of the LP gas. You now have a gas engine with a diesel ignition source.
Where have you got your figures from that say that LPG has a higher detonation point than Diesel fuel.You seem to have no idea when it comes to understanding the combustion difference between something with 50 Cetane versus 105 Octane. 
The ignited diesel replaces the spark plug. I get it. Will CF?
please stop thinking flash point and start thinking autoignition temps please, you are just consfusing yourself that way.

No we don’t because common sense tells me that the idea would’nt work .

Im trying god I am trying to get him to understand, maybe its because I am a women he thinks I dont know what I am talking about.

Think you’ll find that’s what those octane and cetane numbers refer to.

I always thought that a woman’s place is in the home and you’ve proven me right.

Ok I give up its like trying to teach physics to a blind, deaf mute frenchmen.

Not until someone from the oil companies comes on here and explains how a fuel with around 105 octane rating can have a higher temperature detonation point than diesel with 50 Cetane in which case we’ve been running petrol engines with far less compression than they could have been run at. 
Common sence would say that an atomic bomb would produce an explosion when what it is is an implosion, hence the need for a shaped charge to ignite it.
“If it were left up to man’s common sence we would still be in the dark ages. The human mind expands our understanding of the infinite universe but you have to let go of common sence to achieve this.” Dr Stephan Hawkings

Even a blind deaf mute Frenchman would know that he could’nt run the same amount of compression in a petrol engine as a diesel because 90-100 octane detonates under far less compression than 50 Cetane will.
Not until someone from the oil companies comes on here and explains how a fuel with around 105 octane rating can have a higher temperature detonation point than diesel with 50 Cetane in which case we’ve been running petrol engines with far less compression than they could have been run at.
And that is why you will forever remain a mental midget.

Would this help?

I doubt it this is carryfast we are dealing with.

But he knows as much about running car and truck engines as you do.But try telling those Japs who were in Hiroshima that it was an implosion not an explosion that blew all of them up.
I’m no Einstein but I thought the shaped charge was needed to push the nuclear fuel together fast enough for the nuclear reaction to take place fast enough to make an explosion not a power station.
It is the implosion and the mass created that causes the outward expantion. Just like a super nova in the creation of a black hole. Physics would do you good to learn some. I bet he knows a hell of a lot more than you do about the physics of combustion. Which obviously is not very difficult I am sure I could explain this to a 5th grader and have them understand it.

Did they have 5th grade at Borstall?

But clever enough to know that a diesel engine won’t run on Petrol.

Would that be because there isn’t enough compression in a diesel engine to raise the temperature to the point the petrol autoignites?
