What is the function of the intake and exhaust solenoid valves? What are the consequences if the intake and exhaust solenoid valves are broken?

Intake and exhaust Solenoid valve function

The automobile solenoid valve is an actuator of the electronic control system. It mainly functions as a switch. It uses electric energy to flow through the coil to generate electromagnetic suction to attract the valve core (overcoming the spring or self-gravity). It is divided into two categories: normally open and normally closed.

What requirements require thissolenoid valve? When it is necessary to cut off the flow of oil, water, gas and other substances, it can be used with electrical equipment such as pressure and temperature sensors to achieve automatic control. For example, the gasoline solenoid valve plays the role of opening and closing the oil circuit.

Simply speaking, the intake and exhaust solenoid valves are exhaust brake valves controlled by an electronic system. The exhaust brake valve is installed between the exhaust pipe and the muffler. Trucks use this valve to control the flameout of the internal combustion engine.

The intake and exhaust solenoid valves are broken. What impact

A broken intake solenoid valve will cause the engine to work abnormally or lack power. At high, medium and low speeds, the engine will work unevenly and vibrate rhythmically. The muffler will emit black smoke and fire. The engine's speed and power will decrease, and the vibration will be severe, making driving difficult. Noise increases.

If the intake and exhaust camshaftsSolenoid Valve Well, the engine fault light will come on, and the engine power will also be severely reduced. . The engines of most automobiles basically use a double overhead camshaft design. The camshafts of this engine are installed on the cylinder head.

Double overhead camshaft engines have two camshafts, one to adjust the intake valve and the other to adjust the exhaust valve. The camshaft and valves are basically the valve mechanism of the engine, and the valve mechanism is very crucial to the engine.

Most engines basically use a four-valve design per cylinder, with two intake valves and two exhaust valves among the four valves. During the suction stroke, the intake valve will open and the exhaust valve will close. During the compression stroke, the intake and exhaust valves will basically close. During the power stroke, the intake and exhaust valves will basically close, and during the exhaust stroke, the intake valve will close and the exhaust valve will open.

Some engines are equipped with a variable valve timing system and a variable valve lift system. This system can change the valve timing and lift according to different working conditions, which can improve efficiency and reduce fuel consumption. Engines with variable valve timing have solenoid valves on the camshaft. If this solenoid valve is bad, it will affect the engine's power reduction.
