The rest of the derivation is written below: How i calculate the mean effective pressure of cylinder in diesel engines. The compression ratio is 9.5, and the engine is.

So It Is Clear That Power Of An Engine Increase By Increase Either Of Mean Effective Pressure Or Specific Piston Speed Or Both.

The mean effective pressure (mep) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. Mean effective pressure is the ratio of work done (w) during the working stroke(s) of a cycle to the stroke volume or swept volume (vs) of the cylinder. Stroke cycle at 3600 rpm.
