The working principle of the intake camshaft solenoid valve, what is the problem when the intake camshaft solenoid valve is broken?

Intake cam Working principle of shaft solenoid valve

The working principle of the camshaft solenoid valve is to block or leak different oil drain holes by controlling the movement of the valve body. The oil inlet hole is normally open, and the hydraulic oil will enter the different oil drain pipes and then pass through the oil drain pipes. The hydraulic pressure pushes the piston, which in turn drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.

1. Difficulty in starting: When the camshaft solenoid valve fails, the solenoid valve cannot open and close freely, which will cause difficulty in starting the car;

2. Inability to accelerate: When the camshaft solenoid valve fails, the oil drain hole may be closed, and fuel is lost. Without effective transmission and combustion, the car will feel weak when accelerating;

3. The vehicle is prone to stalling after starting: If the solenoid valve suddenly closes or does not work properly when the car is started, the engine will stall;

4. The vehicle fault light is on: There are many reasons why the vehicle fault light is on, and the camshaft solenoid valve failure is one of them.

The steps to disassemble and install the intake camshaft solenoid valve are as follows:

1. Take out the water pipe on the engine cover. Be careful not to use a screwdriver to prevent scratching the water pipe. Remove the cover, the intake solenoid valve is as shown by the arrow, the socket is gray, and the exhaust is black;

2. Lift the white safety buckle on the plug. You can use a flat-blade screwdriver to gently push it up at the arrow, then press the black buckle in the middle to pull out the plug;

3. Use a 10 mm sleeve to unscrew the solenoid valve fixing screws ;The old solenoid valve is a little tight. You can use a flat-blade screwdriver to gently pry it up at the top socket. Be careful not to get the surrounding sand and dust inside;

4. Add new Solenoid valve and fix the screws , just tighten it slightly. The cylinder head is made of aluminum alloy;fasten the plug, replace the engine cover and fix the water pipe, start the test run, and if possible, use X431 to eliminate the fault code (eliminate it when starting).
