Otto Cycle

Otto cycle consists of two isoentropic and two isochoric processes. Heat is supplied and heat is rejected by the cycle during isochoric process.

Where,
1-2: Adiabatic compression
2-3: Isochoric heat addition
3-4: Adiabatic expansion
4-1: Isochoric heat rejection

Heat supplied during constant volume process 2-3
Heat supplied by the air during constant volume
Heat rejected during constant volume process 4-1
Heat rejected by the air during constant volume
The thermal efficiency of Otto cycle can be given by the formula
