How much does it cost to clean the southeast dx7 throttle, and how long does it take to clean the southeast dx7 throttle?

How much does southeast dx7 need to clean the throttle? Southeast dx7 needs about 100 to clean the throttle once. How often does the southeast dx7 throttle need to be cleaned? This car is about 10000km to 20000km. It is more suitable for cleaning the throttle. Throttle is a controllable valve to control the air entering the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, 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 mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air. 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 control accuracy, and linear electromagnetic type is rarely used in automobiles because of its high power consumption. DC servo motor overcomes the above two situations, so it is widely used in automobiles. In addition, the throttle valve also needs to be replaced regularly, and the length of time mainly depends on factors such as the quality of air filter, the quality of engine oil and the road conditions of vehicles. Dirty throttle is mostly caused by poor air and oil quality. The carbon deposit produced in the process of gasoline combustion will infect the throttle valve due to negative pressure, which will make it close poorly, thus increasing the intake air, causing signal transmission errors, leading to high fuel consumption and engine idling jitter.
