Thermodynamic Diesel Cycle – Animation

Thermodynamic cycle Diesel - Animation

Diesel cycle

In this animation a plunger cylinder is loaded and discharged with mass, varying the volume and pressure within the cylinder and the force exerted on the gas. A gas nozzle provides thermal energy to this system by making the burn function in the internal combustion engines. The characteristic curve of the Diesel thermodynamic cycle is plotted in the PV (Pressure x Volume) diagram.


This thermodynamic cycle is present, for example, in internal combustion engines which use fuels that burn slowly, expanding their volume and pushing the piston, while the pressure inside the cylinder remains constant. Stationary engines driven by Bahian oil, fuel oils or coal dust, for example, operate under this cycle.
