what is air standard efficiency? why we need to calculate Air standard efficiency of engine?
Air standard efficiency is base on an air standard cycle or Carnot cycle as shown in the link below [1] concerning the thermodynamics of internal combustion engines.
The air standard efficiency is used as a base line to provide a standard point for evaluating different types of engines against one another.
The link also provide some analysis of different air standard cycles that could be evaluated base on the different types of engines – otto cycle, diesel cycle and Joule cycle.
