Addition Cycle Dual Heat Process

Click For Summary

SUMMARY

The heat addition process in a dual cycle occurs first at constant volume followed by heat addition at constant pressure to maximize energy retrieval. This sequence enhances the efficiency of the cycle, as demonstrated by analyzing the PV diagram where the area enclosed by the PV curve represents the net work produced. The dual cycle effectively combines features of both Otto and Diesel cycles, optimizing performance.

PREREQUISITES

Understanding of thermodynamic cycles, specifically Otto and Diesel cycles.
Familiarity with PV diagrams and their significance in thermodynamics.
Knowledge of heat addition processes in thermodynamic systems.
Basic principles of energy retrieval and efficiency in engines.

why in dual cycle heat addition at constant volume process is first then after heat addition at constant pressure process is done?

Because you can retrieve more energy this way. Draw the PV diagram and compare the area enclosed by the PV curve in the diagram. It represents the net work of the cycle.
