DDiesel cycle
Answer
Correct Answer: Diesel cycle
Explanation
Concept/Approach
- Diesel cycle: isentropic compression → constant-pressure heat addition → isentropic expansion → constant-volume heat rejection.
- Otto: two isentropes + two constant-volume processes.
- Carnot: two isotherms + two isentropes. Stirling: two isotherms + two constant-volume processes with regeneration.
