A Study on Variable Parameters of Bio-Diesel Fuel Injector
By using 3D CFD software FIRE mist spray model for bio-diesel fuel injector of the diesel engine was revised and the combustion process of the bio-diesel was simulated in it.Then the effect of spray angle, injecting orifice diameter and fuel injection advance angle on cylinder pressure and heat release rate were analyzed when bio-diesel was bumedThe results showed that;with increasing of spray angle,the orifice diameter is reduced:With the increase of fuel injection advance angle,the maximum cylinder pressure rise rate was increasedWith the increasing of spray angle, injecting orifice diameter and injection advance angle, the peak heat release was decreased/The calculation results provided basis for testing and analyzing fuel injector of diesel engine fueled with biodiesel.
