| Abstract: | To settle the seal matters in valve train system,a new preinjection NC air-powered engine was designed,its thermo-dynamics model was proposed.The model was made up of the thermo-flow rate equations of preinjection cylinder & working cylinder and the dynamics equations of the engine.The operating process and efficiency factors of the engine were quantitatively researched by varying parameter dynamic simulation.Simulation result shows that the temperature of preinjection cylinder is close to 383.5 K when air ... |
