Why is the car throttle always dirty? Has the computer been cleaned? Or take it down and clean it?

Because engine oil and gasoline may stick to the valve at high temperature and form carbon deposit on the throttle, it will affect the opening and closing of the valve in serious cases, and customers will feel that the engine is weak.

I don't know what you mean by computer cleaning.

Generally speaking, there are two ways to clean. When the new car is guaranteed for the second time, the original fuel cleaner can be added. Its function is to contain cleaning agent. When the fuel washes to the valve, the cleaning agent can penetrate into the carbon deposit, and then it will clean the valve. These are anti-micro-duration, generally used for the second time, and then can be considered once every 20,000-30,000 kilometers. There should be no problem; There is another kind, of course, disassembly and cleaning, but disassembly and cleaning will hurt bones and muscles, which is basically equivalent to disassembling the whole engine (ordinary automobile engine).

Auto repair shops also have some compromise maintenance methods. You should ensure that: 1, and confirm whether the detergent is officially approved; 2. How can the cleaning agent be discharged from the engine after cleaning? Let the repair shop explain this to you.

If this happens repeatedly, you should pay attention to maintenance:

1, the valve sealing ring has aged, resulting in continuous oil leakage;

2, injector failure;

The gasoline used is inferior.

4. Usually driving is often below 40 kilometers; etc
