What's wrong with the accelerator of Changhe Freda?

The fault of the throttle valve in Changfuda River may be that the exhaust pipe emits black smoke and the gasoline consumption is too high.

Throttle definition:

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.

Throttle classification:

There are two kinds of throttle valves: traditional cable throttle valve and electronic throttle valve. The traditional engine throttle control mechanism works through a pull wire (soft steel wire) or a pull rod. One end of the pull wire or pull rod 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.
