Where is the throttle?

The throttle valve is located behind the air cleaner element of the intake system and in front of the intake manifold. Throttle is the throat of the engine, which can control the intake of the engine.

When the driver presses the accelerator pedal, he actually controls the throttle opening instead of directly controlling the fuel injection quantity. When the throttle opening becomes larger and the sensor detects that the amount of air entering the engine increases, the ecu will command the fuel injection system to increase the fuel injection amount.

Electronic throttle is used in automobile engine, which can control the amount of air entering the engine more accurately. There is no physical connection between the electronic throttle and the accelerator pedal.

Throttle is easy to accumulate carbon when it is used for a long time, so riders need to clean the throttle regularly during maintenance. If the carbon deposit on the accelerator is serious, it will lead to the phenomenon of unstable idle speed of the car.

After removing the carbon deposit from the accelerator, the computer should be re-matched, otherwise the fuel consumption of the car will increase in a short time.

The engine computer has a strong learning ability. When carbon deposits appear on the throttle, the computer will use another set of control logic to control the throttle. If the cleaned carbon deposit does not match the computer, the computer is still using the control logic of the accelerator with carbon deposit to control the accelerator without carbon deposit, which will lead to the increase of automobile fuel consumption.
