For dual combustion cycle for fixed value of heat addition and compression ratio

Question

Quizplus · Accepted Answer

In a dual combustion cycle, the mean effective pressure (mep) will be greater with an increase in the pressure ratio (rp) and a decrease in the cut-off ratio (rc). This is because increasing rp improves the efficiency of the constant volume process, and decreasing rc enhances the efficiency of the constant pressure process, both contributing to a higher mep.
