An Air-Standard-Cycle-Approximation to the ideal cycles of reciprocating engines has resulted in the prediction that water addition will decrease the indicated efficiency of reciprocating engines. The results show for the relative efficiencies that the ideal Otto cycle > the ideal limited pressure cycle > the ideal diesel cycle. It is concluded that the Air-Standard-Cycle-Approximation can play a useful role in rationalizing the performance of water-added reciprocating engines as it has historically for engines without water addition.
