1.Information
As shown in the gure above, the fuel metering valve is installed at the inlet position of the high pressure oil pump to adjust the fuel Supplyment and fuel
pressure. And its adjustment requires to be controlled by ECU. When the control coil is energized, the fuel metering proportional valve is conduction. Can
provide the maximum ow of fuel. ECU can increase or decrease the fuel quantity by changing the oil content of high pressure oil pump through pulse signal.
Fuel metering valve is an important device in the diesel engine electronic control high-pressure common rail pump, according to the ECU instruction, using
PWM to control and adjust the drive current of fuel metering valve,and then change the displacement of the control valve, so as to adjust the inlet oil quantity
into the high pressure oil pump, thus, adjust and stabilize the pressure of pipeline of high pressure common rail. The fuel metering valve is the key unit in the
high pressure common rail pump of dresel engine.
