How long does it take to clean the throttle to restore fuel consumption?

After cleaning the throttle, it takes about 50 kilometers to restore fuel consumption. In addition, after cleaning and installing the throttle valve, it is not completed, and it is necessary to re-match the driving computer.

The main cause of throttle scaling is engine oil vapor, followed by particles and moisture in the air. Under normal circumstances, the throttle will not produce carbon deposit, and the exterior of Maiwei throttle, which has traveled for 20 thousand kilometers, is as bright as new. But it's different inside.

When the engine intake and exhaust in the working stroke, the airflow is reciprocating, and the gas generated when the valves overlap will flow back to the intake, resulting in carbon deposition. The most important point is the forced ventilation of the crankcase before the throttle. Crankcase ventilation will re-introduce the exhaust gas in the crankcase into the cylinder for combustion through the intake valve, which will also directly lead to dirty throttle.

In fact, there are only two ways to clean, unpacking and no washing. Disassembly and washing is to remove the throttle assembly, clean it with special cleaning agent and then install it again, which will be more thorough.

Cleaning without disassembly is commonly known as "hanging bottles". When the engine is running, the mist cleaning agent is continuously sprayed from the "hanging bottle" at the engine intake. This kind of cleaning takes a long time, but it has many effects. You can also clean the air inlet while cleaning the throttle. Both methods have their own advantages, depending on the specific situation of the owner.
