Detailed Solution
Download Solution PDFExplanation:
The Dual Cycle also called a mixed cycle or limited pressure cycle is a compromise between Otto and Diesel cycles.
The dual cycle is a thermodynamic cycle that combines the Otto cycle and the Diesel cycle. In this cycle, the heat addition occurs partly at constant volume and partly at constant pressure.
Different processes in the dual cycles are given below:
Process 1-2: Reversible adiabatic compression (Isentropic compression)
Process 2-3: Constant volume heat addition.
Process 3-4: Constant pressure heat addition.
Process 4-5: Reversible adiabatic expansion (Isentropic expansion)
Process 5-1: Constant volume heat rejection.
