The temperature of the compressed air in a diesel engine

AI Thread Summary
The discussion focuses on the temperature of compressed air in a diesel engine just before fuel injection and auto-ignition. It seeks to understand the rough temperature range necessary for diesel fuel to ignite. Initial responses suggest that diesel fuel typically ignites at temperatures around 210-250°C (410-482°F). The conversation references external sources for more detailed information on ignition temperatures. Understanding these temperatures is crucial for optimizing diesel engine performance and efficiency.

Hi,

Could someone tell me the rough temperature the air gets to under compression, just prior to the diesel being injected and auto igniting?

thanks in advance

Ok thanks.

Suppose what I'm really asking is what sort of temperatures does diesel ignite?
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
