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?
 
I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...
Hi. I noticed that all electronic devices in my household that also tell time eventually lag behind, except the ones that get synchronized by radio signal or internet. Most of them are battery-powered, except my alarm clock (which runs slow as well). Why does none of them run too fast? Deliberate design (why)? Wrong temperature for quartz crystal? Decreasing battery voltage? Or just a coincidence?
