Where is the throttle of Guo Si V348?

Between the air cleaner and the engine block.

Throttle is the most important component in 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. It connects the air filter with the cylinder block. The throttle valve is slightly cylindrical, and there is a disk rotating around the axis in the center of the cylinder. With the rotation of the disc, the cross section of air circulation in the cylinder will be controlled, thus controlling the flow of mixed gas.

There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator 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.
