Where is the throttle icon?

The throttle valve of an automobile is usually located at the engine intake, behind the engine air filter element and in front of the intake manifold.

The position mentioned above is only the position of most models, not all throttles are in this position. The throttle position of a car will be different for different models.

Throttle is called the throat of an automobile engine. Because the throttle valve is connected to the air cleaner, it is connected to the engine block.

The main function of throttle valve is to control air intake, which will affect fuel injection. When the intake air volume increases, the fuel injection quantity will also increase. Therefore, the throttle valve is a device to control the air intake and fuel injection into the cylinder.

The throttle we step on is actually not to control the injection amount of gasoline, but to control the opening of the throttle.

The deeper you step on the accelerator, the greater the throttle opening, the greater the air intake, the greater the fuel injection, and the stronger the vehicle power. On the contrary, if the accelerator pedal is shallow, the throttle opening is small, the air intake and fuel injection are small, and the fuel injection of the car is small, the power of the car will be weak.

There are two kinds of throttle: traditional cable throttle and electronic throttle. Now more and more vehicles use electronic throttle. Electronic throttle can control the throttle opening more accurately, and then get better control in environmental protection and fuel economy.
