Efficiency of combustion

WebMathematically, combustion efficiency can be expressed as: ηcombustion= {Fuel Energy - Σ(Energy of Partial Combustion Products)}/(Fuel Energy) (6) The combustion efficiency can be estimated using fuel consumption and engine-out emissions data [391]. WebInternal combustion engines are modeled by the Otto cycle rather than by the Carnot cycle. Looking at this link for the Otto cycle (or this great link from MIT), you may observe that in this cycle there are four temperatures involved, and the efficiency is given by $$ \epsilon_O = 1-\frac{T_4- T_1}{T_3 - T_2}. $$
