Polo, where's the throttle?

About the landlord's concern about "where is the polo accelerator?" The following is my personal opinion:

The polo throttle is located behind the air intake. When you find the engine air filter, you will basically find the throttle. Throttle is called the throat of an automobile engine. Because the throttle valve is connected with the air filter and the engine block, the key function of the throttle valve is to adjust the intake air quantity, which will be related to the fuel injection quantity. As the air intake increases, the fuel injection will increase, so the throttle valve is a device to adjust the air intake and fuel injection into the cylinder. There are two kinds of throttle: traditional cable throttle and electronic throttle. At present, more and more models basically use electronic throttle. Electronic throttle can adjust the throttle opening more accurately, and then it can be better adjusted in terms of environmental protection and fuel rationality.
