What is the composition of the throttle body?

Cars have become an essential tool for everyone to travel. Of course, automobile knowledge is essential. In order to make it easier for everyone to understand this knowledge, Bian Xiao will introduce this problem about the composition of throttle body today. If you are interested, it may help you.

The throttle body is a valve that regulates the intake of the engine. It is a circular steel plate with a shaft in the middle, which is connected with the throttle cable and adjusted by the throttle cable. The throttle body is a device in the engine intake system. Throttle body is mostly divided into three parts: actuator, throttle blade and throttle position sensor, and most of them are packaged as a whole. On the water pipe side, the exhaust gas flows back to the necessary emission specifications. Throttle is a controllable valve, which is used to regulate the air entering the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is connected with the air filter at the top and the engine block at the bottom, and is called the throat of the automobile engine. There are two kinds of throttles: traditional pull-wire and electronic throttles. The traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle key uses the throttle position sensor to adjust the throttle opening according to the energy required by the engine, and then adjust the intake air. In addition, there are four types of electronic throttles: electro-hydraulic type, linear electromagnet type, stepping motor type and DC servo motor type. However, electro-hydraulic type and stepping motor type are rarely used in automobiles because of their low adjustment accuracy, and linear electromagnetic type is rarely used in automobiles because of its high power consumption. DC servo motor type overcomes the above two situations well, so it will be widely used in automobiles. In addition, the throttle should be replaced regularly, and the key time should be short of filter quality, engine oil quality, driving road conditions and other factors.
