Describe all processes in Otto cycle and Diesel cycle and plot its P-v and T-s diagram respectively
Otto cycle:
Otto cycle is the ideal cycle for the spark-ignition or gasoline engine. This air-standard Otto cycle is composed of four processes:
1-2: isentropic compression
2-3: isochoric heat addition or constant volume heat addition
3-4: isentropic expansion
4-1: isochoric heat rejection or constant volume heat rejection
Diesel cycle:
Diesel cycle is the ideal cycle for the compression-ignition engines. it is composed of following processes:
1-2: isentropic compression
2-3: isobaric heat addition
3-4: isentropic expansion
4-1: isochoric heat rejection
