Alfa Romeo giulia, where's the throttle?

The position of the throttle valve is at the air inlet of the engine, behind the filter element of the engine air cleaner and in front of the intake manifold. The position of the automobile throttle valve will vary according to different models. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. Pay attention to the cleaning and prevention of the throttle: 1, and disassemble and clean it; 2. Correct some mistakes in cleaning the throttle valve; 3. The fouling of the throttle is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle will be much slower.
