Piston and cylinder.

Adiabatic expansion process power. Combustion ends and power stroke begins.
Isochoric cooling (Qout): Heat rejection. Power stroke ends, heat rejection starts.
Isobaric compression: Exhaust
Isobaric expansion: Intake
Adiabatic compression
Isochoric heating (Qin): Combustion of fuel (heat is added in a constant volume; the burning of the gasoline-air mixture is instantaneous)
