Does the engine of 1.4TSI have a throttle? Does the throttle get dirty easily?

The throttle valve is behind the air filter, and LZ wants to express the valve (generally there are intake valves and exhaust valves), and the valve is above the cylinder. Generally, it is not a direct injection engine, and gasoline and air are mixed in the intake pipe, so there will be gasoline mixed gas to pollute the valve, but the problem is not big. After all, it is a mixed gas, not a liquid. When we step on the accelerator at ordinary times, we actually control the opening of the accelerator and change the air intake according to the change of the opening of the accelerator. German cars generally use air flow meters, while Japanese cars generally use air pressure sensors and temperature sensors together. The purpose of the above two vehicles is the same, that is, to calculate the air quantity, send the signal to ECU, and then ECU controls the fuel injection quantity! ! So we usually clean the throttle in order to let more air enter the intake pipe from the front, and the power is better!
