Introduction

Otto Cycle.

Piston and cylinder.

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