How to Evaluate Diesel Efficiency?

Diesel Efficiency evaluator uses Diesel Efficiency = 1-1/(Compression Ratio^Gamma-1)*(Cutoff Ratio^Gamma-1/(Gamma*(Cutoff Ratio-1))) to evaluate the Diesel Efficiency, Diesel Efficiency in a cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. Diesel Efficiency is denoted by DE symbol.
