What does the fuel pressure control valve do?
The job of the fuel control valve is to maintain a constant pressure in the common-rail fuel rail. When the rail empties, the valve shuts and allows fuel from the high pressure pump to fill the rail again. As the rail fills to maximum, the valve opens to allow fuel to escape back to the vehicle’s fuel storage tank.
Where is the fuel pressure control valve located?
A fuel pressure regulator is located at the end of the fuel rail and it connects to the injectors of the car. To locate the fuel regulator, you must first find and follow the fuel rail in your engine and you can find it at the end, before the fuel gets into the engine.
How is a fuel pressure sensor used in adaptive fuel control?
This kind of adaptive fuel pressure control consists of a mechanical high pressure fuel pump with fuel metering valve, see figure 1, and a fuel rail with fuel pressure sensor. The high fuel pressures used in these systems also improve fuel atomization at the injector nozzle.
What sensors control fuel injectors?
The injector control pressure sensor is an engine management component that is commonly found on diesel engines. As its name implies, it is an electronic sensor that monitors the fuel pressure going to the injectors.
Where does the fuel pressure sensor go in a car?
This sensor is an electronic device which calculates the fuel pressure and then sends this information to the PCM (powertrain control module). The PCM is the main computer of a vehicle. It is responsible for managing how the engine functions and supplying it with what it needs to sustain its operation, such as its fuel needs.
What’s the name of the fuel pressure regulator valve?
This is a modal window. The Fuel Pressure Regulator solenoid is called the PRC solenoid for Mazda vehicles, also known as the Pressure Regulator Control solenoid, EGR Valve and Vacuum solenoid valve (VSV). 2.After restart.
