The working principle of the oil pump solenoid valve, the symptoms of the oil pump solenoid valve being broken

Oil pump solenoid valve How it works

is a two-position, two-way distributor, and the system controls the oil supply time of the distributor. When solenoid valve is connected to a high level, the electromagnet of the solenoid valve attracts Close to open the 2-position 2-way indexer to lubricate all parts of the machine tool. When it is low, the electromagnet loses power. The indexer is closed and does not lubricate the machine tool.

The fuel metering proportional solenoid valve is installed at the oil inlet position of the high-pressure oil pump and is used to adjust the fuel supply volume and fuel pressure value, and its adjustment requirements are controlled by the ECU. The fuel metering proportional solenoid valve is conductive when the control coil is not energized and can provide the maximum flow of fuel. The ECU changes the oil inlet cross-sectional area of ​​the high-pressure oil pump through pulse signals to increase or decrease the oil supply.

Oil pump solenoid valve is broken symptoms

When a car oil pump When the solenoid valve is damaged, the car's oil system will malfunction, and the difficulty of throttle adjustment will also increase. When the car presses the accelerator, problems such as jumping or stopping of refueling may occur.

Oil pumpSolenoid valve There is a closed chamber inside. Basically there are holes at different positions, and each hole is basically connected to different Oil pipe. There is a piston in the middle of the chamber and electromagnets on both sides, which can open or close the oil drain hole by adjusting the movement of the valve body.

In most cases, the oil inlet hole is normally open, so that the hydraulic oil will enter the different oil drain pipes, and then the engine can work normally. When the solenoid valve of the oil pump is damaged, the engine oil cannot be transported normally, which will affect the power output of the car when refueling and affect the normal operation of the engine, causing the car to have symptoms such as weak acceleration, no refueling, idling jitter, and loud engine noise.

The automobile oil system is very important in the automobile, equivalent to the blood vessels of the human body. Therefore, when the car travels up and down every 2,000 kilometers, the car's oil system needs to be tested to prevent blockage and cause car failure. When adding fuel, it is best to add high-quality fuel, which is not easy to precipitate, so it is not easy to cause carbon deposits and block the car's piping system.
