Nguyên lý hoạt động của kim phun

Fuel from the high-pressure pump comes out with a certain pressure when it passes through the oil pipe and will be led into the high-pressure injector.

Here it will be inserted into the spring and injector cavity. The injector opens only when the oil pressure must be greater than the spring compression. Then the cone will be opened to help fuel through.

Immediately after the injection process ends, the pressure will decrease and the cone will close again. That process repeats itself and depends entirely on the pressure generated by the high-pressure pump.

The compression pressure from the spring can be adjusted through the adjustment knob, which can be tightened or loosened at will. The compression of the spring is therefore also increased and decreased. The nozzle pressure was then also changed.
