Diesel Cycle Heat Rejection Analysis
The ideal diesel cycle comprises four key processes:
- Isentropic compression
- Heat addition at constant pressure
- Isentropic expansion
- Heat rejection at constant volume
In the standard analysis of the diesel cycle, the process following the isentropic expansion (step 3) is the return to the initial state. This return path, representing heat removal, is modeled as occurring at constant volume. This step brings the working fluid back to its starting temperature and pressure before the compression stroke begins again.
Consequently, heat rejection in an ideal diesel cycle happens during the constant volume process.
