charging, EGR, charge air cooling and a complicated fuel injection process. The fuel injection procedure is important for the combustion and emission formation within the aero engine. The gas injector has to atomize and vaporize the gas as it is injected. Sooner or later of the combustion the
A fuel injector is an electro-controlled valve that uses to spray out the fuel. In the petrol fuel injection system, the injector acts as a door to spray fuel from fuel lines into the intake manifold. The injector function is not only a sprayer, but the injector also atomizes the fuel in the intake manifold. When fuel is in atomization form ...

dimensions are referred to for designing the nozzle. The fuel injection nozzle comes under the function of the high pressure of the fuel even as the fuel injector is injecting, even as the pressure of the fuel within the fuel injection may be very low when the injection is give up. The liquid load the fuel injection receives is trade.
