What is a door protection program?

The throttle is a sail above the lower seat of the carburetor. Its function is the same as that of carburetor, and it is used to control air intake. Carburetor is a precise mechanical device, which mixes a certain proportion of gasoline and air through the vacuum generated by engine work. At the same time, there are two kinds of control valves: traditional wire throttle and electronic throttle. After gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be ignited to generate power. Therefore, carburetor and throttle valve are called the "throat" of automobile engine, which connect air filter and engine block. In addition, the flexibility of automobile acceleration is also related to the cleanliness of the throttle. Some car owners will consider removing the throttle for cleaning, which is also a long-term hot topic. At present, the traditional engine throttle control mechanism will work through the cable or joystick, with one end connected to the accelerator pedal and the other end connected to the accelerator linkage plate. The electronic throttle is mainly adjusted by the throttle position sensor according to the energy required by the engine, so as to control the intake air.
