Hello everyone I got diesel engine, and there is a backpressure applied in the exhaust. I know that when the exhaust pressure reaches approximately 6 atm. the engine stalls. The question is, how I'm able to calculate this precisely, especially when the backpressure didn't reach it's maximum value, for example 2 atm. I've been told that it has to deal with mean effective pressure, but I couldn't find the right formula... Thanks in advance Oleg .
