Where is the x5 throttle of Jingyi, which is popular in Dongfeng?

At the engine air intake, behind the engine air filter and in front of the intake manifold. Throttle is the throat of the engine, which can control the air 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 opening of the accelerator. When the throttle opening becomes larger, the sensor will command the fuel injection system to increase the fuel injection quantity after detecting the increase of air entering the engine. All automobile engines are using electronic throttles.
