Why should the car wash the accelerator? What is the function of automobile throttle?

Dirty throttle will lead to power drop, unstable idle speed and serious engine fault light. Therefore, it is necessary to clean the throttle valve regularly; The vehicle is in normal use. Usually, the throttle valve needs to be cleaned about every 20000 kilometers. If the environmental quality of the vehicle use area is poor and there are many dust particles in the special gas in the air, it is recommended to clean it about 1000 km in advance; There are two ways to clean the throttle valve. One is to avoid disassembly and cleaning. One is to remove it and clean it. In fact, they are almost the same. The key is to check the operation of the maintenance technician.

Throttle is generally installed at the air intake of the engine. The upper part is the air filter of the car, and the lower part is connected with the engine body. Therefore, the throttle is compared to the throat of the engine; Throttle valve is a kind of valve with adjustable opening and closing size. Just as the faucet can adjust the water flow, the throttle can also adjust the amount of air entering the engine. Air enters the combustion chamber in the engine through the throttle valve and mixes with the fuel injected by the electronic nozzle to form combustible gas. Combustible gas burns in the engine to do work, thus driving the car;

If there is more combustible mixture, the engine speed will be faster. If there is less combustible mixture, the engine will rotate slowly. So, the throttle can control the engine speed, which is different from other parts of the car? The accelerator pedal? The function is the same. At first, the accelerator pedal of a car was connected with the accelerator through some mechanical structure. As soon as you step on the accelerator, it will open. The lower the accelerator pedal, the larger the accelerator pedal, and the faster the car accelerates;

Avoid using the electronic control part of the throttle, that is, the throttle motor, except for special cleaning agents. Avoid getting wet when cleaning. When cleaning the throttle valve, due to the need of cleaning, the throttle plate will be moved to change the original position to cooperate. This needs attention. After cleaning, the computer must be used to restore the original opening. Otherwise, the computer will default the current opening to the original opening, resulting in a large intake flow and unstable idle speed.
