Xuanyi disassembly and washing accelerator fault code is on.

There is carbon deposit in the engine cylinder, which must be accumulated after the engine is used for a period of time. These carbon deposits themselves will lead to the change of engine design parameters, and at the same time, their properties are unstable, and the accumulation of heat will lead to disorderly ignition of the engine, which will lead to engine knocking. In this case, the engine fault light will light up.

Solution: Clean up the carbon deposit in the engine cylinder.

Precautions for cleaning

1, which should be dismantled and cleaned;

2. Correct some mistakes in cleaning the throttle valve;

3. The fouling of the throttle valve is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle valve will be much slower.

The crankshaft is built in the crankcase, and the lower part is connected with the oil bottom. The working temperature of this part is about 100 ~ 180.
