Numerical simulation of the effects of the Nozzle parameters on in-cylinder fuel and air mixing process
Applied Mechanics and Materials(2013)
摘要
In order to study the injection property of diesel engine fuel injector, the three-dimension combustion model of TBD620 diesel engine is constructed on the AVL Fire software platform. A numerical simulation of the two injectors' fuel injection process at different load conditions has been done. The influence on fuel and air mixing process is analyzed. The results show that the special injector has a good performance at low load, but the standard injector is more favorable for fuel and air fully mixing at high load.
