How often is the throttle valve cleaned?

How often does the throttle need to be cleaned? The automobile accelerator needs to be cleaned every 15000 km. Carbon deposit will be produced when the engine is running, and many parts need to be cleaned in time. Besides the throttle, there are idle valve, air inlet, fuel injector, combustion chamber, oil circuit and three-way catalytic converter. These parts need to be cleaned regularly. Now all cars use EFI engines, and the throttle is the most important accessory in the EFI engine system. The upper part of the throttle valve is an air filter grille, and the lower part is the engine block. How fast a car accelerates has a lot to do with the cleanliness of the throttle. Improper throttle cleaning can reduce fuel consumption and make the engine run more smoothly. The reason of carbon deposition in the throttle valve is that the engine works for a long time, the external air quality and the fuel quality used will have an impact on the throttle valve, and the driver's driving habits will also have a certain impact on the throttle valve, so it is necessary to clean the throttle valve regularly to ensure the normal operation of the engine. Cleaning the throttle requires removing the throttle.
