AIR STANDARD CYCLES

AIR STANDARD CYCLES
Because the products of combustion are not too different from air (in terms of thermodynamic properties) we can analyse the engine cycle as a series of reversible non-flow processes using air as the working fluid throughout the cycle.This is known as an air-standard cycle.
