Are intake valves and throttle valves the same thing?

Bian Xiao provides you with the following information about "Is the intake valve and throttle the same thing?" ：

Intake valve and throttle valve are not the same thing. The function of the intake valve is to draw air into the engine and mix it with fuel for combustion; Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful.

The symptoms of automobile valve damage are as follows:

2. When the blade makes abnormal noise, the engine will have unstable idle speed or poor acceleration, and the overtaking performance will also be reduced. In severe cases, it will also lead to engine starting difficulties, misfire, air leakage in the car or increased carbon deposition;

3. The rupture of the valve will lead to the unstable operation of the cylinder, the engine shaking, the engine working inability, the blockage of the exhaust pipe, and even black smoke in serious cases.
