The unstable idle speed of your car teaches you how to clean the accelerator of your car.

If the idle speed of your car is unstable, it may be because the accelerator is dirty and it needs washing. The accelerator is like the soles of our shoes. If it is dirty, it must be dirty. If you go to the 4S store to clean it, you can't escape two or three hundred dollars. It may not be cleaned. In fact, the owner can completely clean the throttle by DIY, and the operation is not as complicated as expected. In this issue, the owner's school will briefly demonstrate the operation of DIY cleaning throttle for you.

Because of the ventilation function of engine crankcase and the function of activated carbon canister solenoid valve, a small amount of gasoline vapor will be brought to the throttle, and the oil and gasoline attached to the throttle will continue to attach to dust. How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and so on. Dirty oil, long-term non-replacement of air filter and poor quality of air filter will aggravate the dirtiness of throttle valve.

Note: The models shown in this paper are FAW-Volkswagen 20 1 1 Golf 6 1.4TSI manual comfort type. The method introduced in this paper can be used to clean the throttle of all models of Volkswagen EA11.4t engine, and 1.8TSI and 2.0TSI models can also be used as reference. This article strictly follows the official maintenance manual of Golf 6. Different brands of vehicles will have different throttle positions and disassembly methods. Please don't try it easily without a maintenance manual.

● The throttle valve is equivalent to the "throat" of the engine.

Throttle is a controllable valve, which is used to control air to enter the engine. Above (or in front of) it is an air filter, and below it is an engine block. The position of the throttle valve is equivalent to the "throat" of the car. After the air enters the intake pipe, it needs to pass through the throttle valve, and then it is mixed with gasoline to form a combustible mixture, which participates in combustion and does work. Whether the idle speed of the car is stable and whether the acceleration is flexible is closely related to the cleanliness of the throttle.

As long as we find the air filter of the car, we can finally find the throttle. The golf 1.4TSI we demonstrated is very special. Because it is equipped with a turbocharged engine, there is also a pressure reducing valve on the intake pipe between the air cleaner and the throttle valve, which is connected by a pressure pipe. Although the structure is different from other naturally aspirated engine models, it is not difficult to remove the throttle valve, and only an ordinary screwdriver is needed to solve it.
