A dual cycle is one in which the heat is supplied at

Explanation:

Dual Cycle

• 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:

1. Process 1-2: Reversible adiabatic compression (Isentropic compression)
2. Process 2-3: Constant volume heat addition.
3. Process 3-4: Constant pressure heat addition.
4. Process 4-5: Reversible adiabatic expansion (Isentropic expansion)
5. Process 5-1: Constant volume heat rejection.
