DIESEL FUEL SYSTEM - Practice Mode

Explanation:

Diesel cycle is called constant pressure cycle because the heat addition process in diesel cycle is done at constant pressure whereas petrol cycle is called constant volume cycle (Otto Cycle) as here the heat addition is done at constant volume. (Heat rejection in both the cycles is done at constant volume). <br><br> Petrol engines works on Otto Cycle, petrol engines are also called as S.I. Engines.
