BMW throttle opening

I suggest you clean the throttle. Only cars equipped with turbochargers will report such fault codes.

1. The throttle valve 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, which will be successfully formed after combustion. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Throttle four-stroke gasoline engines are generally like this. Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.

Step 2 classify

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.

3. Maintenance methods

How to clean and prevent it should be removed and washed! Correct some misunderstandings of throttle cleaning! The main cause of throttle scaling is oil and gas, followed by particles and moisture in the air. In other words, using qualified air filter and removing the crankcase ventilation pipe will slow down the scaling speed of throttle valve. The crankshaft is built in the crankcase, and the lower part is connected with the oil bottom. The working temperature of this part is about 100 ~ 180.
