spark-ignition combustion cycle, spark ignition combustion cycle; Otto cycle
1. A thermodynamic combustion cycle consisting of four processes that are used in mechanical engineering:
  • An air-fuel mixture is drawn into the cylinder and compressed.
  • Heat transfer is added by the spark ignition of the fuel mixture in the cylinder.
  • The gases produced by this combustion expand to move the piston downward for the power stroke.
  • The burned gases in the cylinder are expelled.
2. A thermodynamic process for the conversion of heat into work; for example, the sequential suction, compression, ignition, and expulsion in a four-stroke engine.

Named after Nikolaus August Otto (1832-1891), a German engineer and inventor.
