Re: Diesel in a high compression gas motor?

Yep. If you tried to compress diesel to 14:1, it would self ignite before you wanted it to. The whole point with diesel is that you compress the air which heats it, then inject the fuel directly into the cylinder and it self-ignites.

If you're thinking about burning diesel in a spark-ignition engine, it won't work. The spark isn't enough to ignite diesel. the other issue is getting diesel to atomize. It requires super high pressure (over 30,000 psi in some diesels) through very sophisticated injectors to get it to atomize. If you tried making an injector spray it into the intake it would almost instantly return to a liquid puddle.

I like how you think, though. Its a fine idea, just that diesel is so hard to get burning without a lot of help.
