Reasons for oil pressure control valve damage？
ignition system failure : the ignition system is a key part of the car must work properly when starting, if the ignition system is faulty, fuel pressure regulator can not start, resulting in damage to the oil pressure control valve.
Fuel supply system failure : The fuel supply system is one of the key systems for regulating fuel use. If the system fails, it may lead to the failure of the fuel pressure regulator, which will affect the normal operation of the oil pressure control valve.
fuel injector, throttle body and idle motor pollution : these parts are closely related to the fuel pressure regulator, long use and lack of cleaning may lead to the fuel pressure regulator failure, which will affect the work of the oil pressure control valve.
electrical failure : The electrical failure of the oil pressure regulating valve may be caused by many reasons, including inaccurate installation and debugging, field vibration and temperature change, resulting in the zero point and range deviation of the output signal of the converter.
Oil pressure control valve damage performance
flameout during driving : Damage to the oil pressure control valve may cause the vehicle to suddenly flameout during driving.
too high or too low oil pressure : damage to the oil pressure control valve will lead to too high or too low oil pressure, which is manifested as too thick mixture, black smoke from the exhaust pipe, lack of power and other problems.
increased fuel consumption : Damage to the oil pressure control valve may lead to a significant increase in fuel consumption, because the unstable oil pressure will lead to abnormal fuel supply.
starting difficulty : Damage to the oil pressure control valve may cause the vehicle to start difficult or even unable to start.
Emissions issues : A damaged oil pressure control valve can result in increased emissions because the unstable fuel supply can affect the engine combustion process.
Keep the pressure in the oil line stable
The main function of the oil pressure control valve is to keep the pressure in the oil circuit stable, and adjust the oil pressure by controlling the opening and closing of the pressure valve.
Specifically, the oil pressure control valve controls the switching of the pressure valve through an internal diaphragm or diaphragm. When the oil pressure is lower than a certain set value, the pressure valve is closed, and the oil pump increases the pressure in the oil circuit; When the oil pressure exceeds the specified pressure, the diaphragm or diaphragm opens, and the over-pressurized fuel flows back to the tank through the return line, thereby reducing the pressure in the oil line. This mechanism ensures that the fuel pressure in the oil circuit is always maintained at a suitable level, avoiding various problems that may be caused by too high or too low pressure.
In addition, the oil pressure control valve is also responsible for accurately adjusting the fuel pressure into the injector according to the change in the pressure in the intake manifold, so that the amount of fuel injected by the injector depends only on its opening time, so as to achieve effective management of the amount of fuel injection. This precise control has an important impact on the fuel economy, power performance and emission performance of the vehicle.
