The throttle valve is the most important component of the EFI engine system. It is the throat of the car engine. Whether the car acceleration is flexible or not has a great relationship with the cleanliness of the throttle valve. When the engine is working, the fuel and a small amount of lubricating oil entering the combustion chamber cannot be 100% burned. The unburned part of the oil is glued to the intake valve, the throttle valve, the intake pipe, the piston or the piston under high temperature and oxidation. The surface of the combustion chamber is further condensed into a mixture of asphaltenes and oils by high temperature to form carbon deposits.
If the throttle valve is excessively carbonized for a long period of time and is not cleaned, the engine may be poorly accelerated, the idle speed may be shaken, and the fuel consumption may increase.
The throttle valve cleaning can effectively decompose and remove the stubborn carbon deposit of the throttle valve, clean the carbon deposits and colloids without disassembling the throttle valve, smoothly open the intake air, improve fuel economy, reduce exhaust emissions, and make the engine run strongly and stably.
It is recommended to clean the throttle valve cleaning about 20,000 kilometers. Of course, different models, different driving habits and different road conditions will be different. In actual vehicles, it is difficult to start cold cars, secondary fires, running jitter, idle speed or low speed. When there is a problem such as flameout and fuel consumption increase, if you can't find another reason, then if you think that the throttle valve has not been cleaned for 20,000 kilometers, then you may wish to clean it.
For owners who do not understand, it is best to go to the repair shop to clean the throttle valve. For those who know the car, they can clean it themselves
