How to calculate the mean effective pressure of a diesel engine?
I want to calculate mean effective pressure (MEP) of a diesel engine. Please help me, you can give me some of the reference.
Thanks

It is going to come down to the variables and data you have on the engine:

It is nothing but the ratio of work done by engine to stroke or swept volume.
M.E.P = W / (Vs)
Use following equation to calcu;ate Pmep.
I.P = (Pmep * L * A * N * k)/60
I.P= Indicated Power
L and A = Stroke length and Area of cross section
N= RPM
k= 1/2 for 2 stroke and 1/4 for 4 stroke
