What will happen to the engine after the exhaust solenoid valve on the car is broken?

If the exhaust solenoid valve on the car is broken, the engine will shake and the power will drop.

A closed cavity is installed in the automobile exhaust solenoid valve, and the solenoid valve is provided with through holes at different positions; Each hole of the solenoid valve is connected with a different gasoline pipeline; The piston moves in the middle of the cavity; Electromagnets are installed on both sides; When the electromagnetic coil is energized, the valve body can be attracted; The automobile exhaust solenoid valve controls the valve body to move and open different oil outlets.

The solenoid valve drives hydraulic gasoline to enter different oil discharge pipes, the piston moves by the power of hydraulic oil, and the piston rod drives the mechanical device. In this way, the exhaust solenoid valve can start mechanical movement, thus maintaining the power output of the engine.

Extended data:

The classification of automobile exhaust solenoid valves is as follows:

1, Direct-acting solenoid valve: When electrified, the electromagnetic force generated by the electromagnetic coil lifts the closing piece from the valve seat and opens the valve; When the power is cut off, the electromagnetic force disappears, the spring presses the closing piece on the valve seat, and the valve closes.

2. Step-by-step direct-acting solenoid valve. When there is no pressure difference between the inlet and outlet, when the valve is opened and the inlet and outlet reach the starting pressure difference, the electromagnetic force will directly lift the closing parts of the pilot small valve and the main valve in turn.

3. When the pilot solenoid valve is energized, the electromagnetic force opens the pilot hole, and the pressure in the upper cavity drops rapidly, forming a pressure difference between the upper and lower parts around the closed part, and the fluid pressure pushes the closed part to move upward, so that the valve is opened;

The pressure source of hydraulic oil is actually solenoid valve and oil circuit system.
