I am very interested in how hot a diesels compression chamber gets right before it shoots the fuel in and ignites. I want to know a formula that I can use to get the peak temperature. I know there are several factors like time and piston/engine heat absorbing, but if the engine is 200F, I think we can use that for something? I am not too good at this stuff but want to learn how to figure this. Let me know what other factors you need to know. Compression ratio is 17.0:1. Bore is 4.02" stroke is 4.72". Thanks for any help you can provide.
