Atkinson Cycle Engine Diagram. For this cycle we have v2 v3 p4 p1 cr v4 v3 pr p3 p4 and tr t3 t1. In the middle of twentieth century a typical steam locomotive had a thermal efficiency of about 6.
But lets start with some explanations. The atkinson cycle engine is a type of ic engine. Two isentropic reversible adiabatic processes alternated with one isochoric process and one isobaric process.
Adiabatic compression 1 2 isochoric heat addition 2 3 adiabatic expansion 3 4 and isobaric heat removal.
Two isentropic reversible adiabatic processes alternated with one isochoric process and one isobaric process. Atkinson cycle 11 this poor output of the atkinson cycle is its major drawback and the reason why it is not widely used as an internal combustion engine. Answer 1 of 5. The atkinson cycle engine is a type of ic engine.
