Why wash the throttle?

At present, everyone knows that the throttle should be washed. Why and to what extent, everyone may not know. Let's talk about the role of the throttle first. It controls the amount of power air required by the engine, that is, the throttle body is used to control the power output of the engine. An engine is a device that converts chemical energy into mechanical energy. When the engine works, it needs carbon to participate in the reaction, and the amount of carbon needed is also the amount of fuel. The computer controls the supply of fuel according to the data of the sensor. There is also a throttle position sensor on the throttle body. The sensor sends information to ECU according to the opening of throttle plate. According to its correct information, ECU calculates and instructs the servo system to control the fuel quantity to achieve the required power output. If the throttle opening information is incorrect, it will lead to inaccurate fuel supply and poor engine combustion. Power drop, serious pollution symptoms.

When the throttle valve is polluted, the valve plate and throttle valve will be buffered, and the valve plate will deflect at a certain angle. At this time, if idling condition is needed, but the information of low-power condition provided by the throttle sensor has been deflected, ECU will provide low-power fuel supply. When the idle air volume reacts with the low-power fuel supply, the mixture will definitely burn too thick and emit black smoke. Resulting in poor combustion. In order to make the combustion return to normal, it is necessary to convert the throttle angle information into correct information. At this time, it is necessary to clean the throttle and restore the correct angle of the throttle.

The so-called throttle cleaning is to restore the correct angle of the throttle, not to clean the throttle body. Throttle washing is not laundry, nor is it confirmed according to cleanliness. It is measured by the angle of throttle recovery.

Matters needing attention in self-cleaning throttle valve. The throttle cannot be initialized because the owner does not have a decoder. When cleaning the throttle, try not to remove the throttle body and unplug the sensor plug, which will cause the angle of the throttle to be too different from the original memory position of ECU, resulting in the phenomenon of engine runaway and car deviation. As long as the valve plate of the throttle valve is restored to the required position, there is no need to require internal cleanliness.
