Introduction

Otto Cycle. Note that the image is wrong. This is for isothermal, not isentropic (adiabatic).

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)
