How many kilometers of throttle cleaning does the knight have?

Knight (check the transaction price | detailed description of the model) Under normal circumstances, the 4S shop will advise the owner to clean the throttle at about 20,000 kilometers. Of course, different road conditions are different, and the throttle of some cars is easy to get dirty. It is not uncommon to need cleaning when it is seven or eight thousand kilometers. Wear gloves before cleaning the throttle, install a nozzle for cleaning spray, and aim at the inside of the throttle to spray.

The throttle can be said to be the engine's? Throat? , connected to the air filter, connected to the engine block, it is reasonable to say that gasoline and engine oil do not go here, it should have nothing to do with carbon deposition, but there is carbon deposition on the throttle. The main reason is that when engine oil or gasoline vapor enters the air intake system through the crankshaft ventilation box, a part will adhere to the throttle valve, and a small part will be impurities in the air.
