Never wash the throttle.

Generally go to 4S shop for maintenance, the staff will say that the throttle must be cleaned, but some people say never wash the throttle. In fact, it is recommended that the throttle valve should not be cleaned frequently. If the cleaning is too frequent or the cleaning solution is unreasonable, the antifouling and antistatic architectural coating on the surface of the throttle valve will be lost, and the throttle valve will be more dirty in the future.

The throttle valve must be cleaned. Because the car has been used for a long time, the throttle will turn black, and a layer of oil stains will be attached to itself and the surrounding tracheal cavity, which is called carbon deposition. If the throttle valve is dirty and not cleaned, it will affect the air intake of the automobile engine, causing the idling jitter and flameout of the automobile engine, and the automobile will continue to accelerate steadily, with a sense of jitter, and the fuel consumption will also increase.

There are many factors that lead to carbon deposition in the throttle, but the main reason is the solidification and accumulation of automobile oil vapor produced by the ventilation pipe of the engine crankshaft after a long time of anti-diffusion, or the flue gas and mixed gas discharged from the cylinder, and naturally some dust residues are likely to leak out of the air filter element. If the car is slow-thinking, dithering and vibrating at idle speed, it means that the throttle is dirty and must be cleaned.

Generally, the throttle valve is cleaned up and down for more than 20,000-30,000 kilometers. Professional foam cleaner can be used for cleaning, and the throttle valve can be disassembled for cleaning. The automobile 4S shop or auto repair shop generally adopts the method of "hanging bottle" for cleaning-in the running state of the automobile engine, the cleaning liquid is continuously sprayed into the air inlet, which takes a long time, but it is very simple to control and can also clean the air inlet by the way.
