There is no need to wash the throttle at all. There are two kinds of traditional throttle and electronic throttle.

The throttle valve needs cleaning. Whether it is necessary to clean the throttle depends on two aspects. One is kilometers. Generally 30,000-40,000 kilometers, it is best to clean the throttle. On the other hand, if the throttle has symptoms similar to carbon deposition, such as weak growth rate and idling jitter, it is necessary to check the throttle. As for the cleaning methods, there are two cleaning methods: disassembly and non-disassembly. If you want to clean it thoroughly, you must take the method of disassembly.

2. At present, there are generally two kinds of throttles in our common vehicles: traditional throttles and electronic throttles.

3. The traditional throttle can be said that the accelerator pedal is directly connected with the opening of the throttle through a steel wire or a connecting rod, so as to control air intake and fuel injection.

4. Electronic throttle is an important control part of automobile engine. It consists of engine, speed sensor, throttle and so on. The electronic throttle control system can accurately control the throttle opening. Electronic throttle is developed from traditional throttle. The steel wire is removed, the throttle position sensor is used to control the opening of the electronic throttle according to the energy required by the engine, and then the on-board computer controls the opening of the electronic throttle, thus controlling the air intake.
