What is a throttle?

Throttle is a controllable valve that controls air to enter the engine.

After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. Known as the throat of an automobile engine, it is connected with the air filter and the engine block. Throttle four-stroke gasoline engines are generally like this. Throttle is one of the most important components in EFI automobile engine system. The upper part is the air cleaner grille, and the lower part is the engine block, which is the throat of the automobile engine.

Where's the throttle?

1. 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.

2. Throttle is a controllable valve to control air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be successfully formed after combustion. It connects the air filter and the engine block, and is called the throat of the automobile engine.
