How to clean the car throttle?

The throttle valve is the throat of the automobile engine, which is located between the air filter and the intake manifold (please see the picture of the operation link below for the specific location). This is a controllable valve, which is used to control air to enter the engine. The depth of stepping on the accelerator is directly related to the opening of the accelerator, so the performance of idle speed and power is closely related to the cleanliness of the accelerator. Let's have a look!

First, how often do you usually clean it?

There is no strict limit on the frequency of cleaning the throttle, which has a lot to do with car habits and environment. If it is dirty, it should be washed. Phenomenologically, cleaning should be considered when the idle speed is unstable.

Under normal circumstances, the 4S shop will advise the owner to clean it once every 20,000 kilometers. Of course, the situation is different for different models. It is not uncommon for some cars to have dirty gas throttles and need to be cleaned after seven or eight thousand kilometers.

Second, what will happen if you don't clean it up?

Failure to clean the throttle for a long time will lead to an error in the throttle opening, and air with impurities will enter the combustion chamber of the engine. These two results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of throttle when driving, reduced power, and even difficult starting and increased fuel consumption.

Third, are all cars suitable for cleaning their throttles?

At present, the throttle of most models is electronic throttle, and only a few old cars or low-end cars are using cable throttle. The two will be different in structure. The cable accelerator will be equipped with an idle motor, which requires special attention when cleaning. For inexperienced car owners, it is recommended not to wash it yourself.

Fourth, how to clean the car throttle?

It is best not to clean the throttle immediately after parking, because the temperature in the cabin is high, which may burn your skin. It is suggested to stop for a while until the engine room temperature drops.

It is necessary to determine the position of the throttle valve before cleaning. The throttle is located behind the air inlet, so it is not far to find the air filter. Every car will be in a different position. The throttle of some models will be covered by the engine cover plate, so it will be more intuitive to open the cover plate for inspection.

Here, in order to keep the car as clean and tidy as possible, many models will be equipped with hood. Most of the covers are plastic, and there are no buckles around them, so many friends dare not remove them hard. In fact, most of the cover plates are fixed by an expanding plastic screws, and we can easily remove them by pulling them vertically. But remember to pull hard vertically, diagonal pulling is easy to damage the screw.

Open the engine cover and you can clearly see the position of the throttle. To remove the throttle valve, you must first remove the hose connecting the air cleaner and the throttle valve. Both ends of the hose are fixed with circular iron hoops, and the iron hoops are fixed with screws. Loosen the screw to pull out the hose.

Suggestion: If possible, it is best to screw the screw with a sleeve, because the screwdriver is easy to make the screw buckle, and the sleeve is relatively safer.
