High pressure common rail fuel injector for trucks

The common rail injector is a component that distributes fuel in the engine combustion chamber. The injection time and duration of the common rail injector are precisely calculated by the electronic control unit, and then the signal is given, which is controlled by the solenoid valve.

In fact, it is a simple solenoid valve. When the solenoid coil is energized, it generates suction. The needle valve is sucked up, and the injection hole is opened. Fuel is sprayed at high speed through the annular gap between the shaft needle and the injection hole at the head of the needle valve, forming a mist, conducive to full combustion

The great advantage of fuel injection is that the fuel supply control is very accurate, so that the engine can have the correct air-fuel ratio in all conditions, not only to keep the engine running smoothly, its exhaust gas can also comply with environmental regulations.
