13 where is the accelerator of Buick excelle?

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 steps on the accelerator pedal, he actually does not directly control the fuel injection quantity, but controls the throttle opening! 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, and all automobile engines are using electronic throttles.

Introduction of automobile throttle

Throttle body mainly includes two types: traditional cable type and electronic throttle. The traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod, one end of which is connected with the throttle pedal and the other end is connected with the throttle 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.

The function of the throttle valve is as follows. Automobile throttle is a controllable valve used to control air entering the engine. After entering the intake pipe, it is mixed with gasoline from different cars, and the mixed part is designed differently, which becomes combustible mixture and participates in combustion and work. One of the steps to power a vehicle.

Throttle is the most important component in today's EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine and controls the speed of the vehicle. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. The owner controls the throttle opening by stepping on the throttle to achieve the purpose of slowing down.
