Description
 
The fuel injector is actually a solenoid valve, its nozzle is facing the intake valve (multi-point out-of-cylinder injection), and its tail is connected to the fuel distribution pipe. The fuel comes from the high-pressure oil circuit, flows to the fuel injector through the channel, and flows to the control chamber through the orifice. The control chamber is connected to the fuel circuit through an oil drain hole controlled by the solenoid valve. When the oil drain hole is closed, the hydraulic pressure acting on the needle valve control piston exceeds its force on the pressure bearing surface of the injector needle valve. As a result, the needle valve is forced into the valve seat and isolates and seals the high pressure passage from the combustion chamber. When the solenoid valve of the fuel injector is activated, the oil drain hole is opened, which causes the pressure in the control chamber to drop. As a result, the hydraulic pressure on the piston also drops. Once the hydraulic pressure drops below the pressure acting on the nozzle needle valve bearing The pressure on the pressure surface, the needle valve is opened, and the fuel is injected into the combustion chamber through the nozzle hole. The fuel injection quantity is determined by the electrical pulse width; pulse width = fuel injection duration = fuel injection quantity, the fuel injector should meet the requirements of different types of combustion chambers for fuel injection characteristics. Generally speaking, the injection should have a certain penetration distance and spray cone angle, as well as good atomization quality, and no dripping phenomenon occurs at the end of the injection.
