Fuel metering valve
The fuel metering proportional valve is installed in the oil inlet position of the high pressure oil pump for adjusting the fuel supply amount and burning
Oil pressure value. The adjustment requirements are controlled by the ECU. Fuel metering proportional valve does not pass through the control coil
When electricity is used, the fuel metering proportional valve is conductive and provides maximum flow of fuel. ECU through the pulse
The rush signal changes the oil inlet cross-sectional area of the high-pressure oil pump to increase or decrease the oil amount.
The fuel metering valve is an important actuator in the diesel electromechanical control high pressure common rail oil pump. According to the ECU directive,
The PWM control is used to adjust the driving current of the fuel metering valve, thereby changing the displacement of the control spool,
This adjustment enters the oil input into the plunger chamber of the high pressure oil pump, thereby stabilizing the pressure of the high pressure common rail pipe.
And the role of regulation is a key component in diesel high pressure common rail pumps.
