Experimental study on the spray characteristics of an air-assisted fuel injection system using kerosene and gasoline

Spray characteristics play a key role in affecting combustion performance of piston aero engines. In this study, spray characteristics of two types of fuel, kerosene and gasoline, were investigated with an air-assisted fuel injection (A2FI) system under different working parameters, which included air and fuel injection duration, fuel-air interval, ambient pressure, fuel pressure and fuel temperature. The macroscopic spray characteristics were...
