How to clean the dirty things on the exhaust pipe, ask the expert for help.

A sponge for washing dishes, the surface of which is green gauze. Buy the high-oxygen degreasing agent for the blue bottle of LOGO in the supermarket, add a small amount of water to the cleaning agent, gently clean it with sponge green gauze cotton for about 1 minute, and then clean the sponge surface with a little force.

Common sense of automobile exhaust pipe cleaning:

1. impurities such as wax and colloid in gasoline filled with high-quality gasoline are the main components of carbon deposition, so the carbon deposition trend of high-cleanliness gasoline is weak. In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline. This can effectively prevent the formation of carbon layer on metal surface, and gradually activate the original carbon particles to be removed slowly, thus protecting the engine from damage. However, the addition of gasoline detergent must be cautious. If counterfeit and shoddy products are added, it will have the opposite effect.

2. Don't idle for a long time. If the idle time is long, the time for the engine to reach normal temperature will become longer. After gasoline is sprayed on the back of the throttle, it will slowly volatilize and produce carbon deposit. At the same time, often idling, the air flow into the engine is also small, so the scouring effect on carbon deposits becomes weak, which will promote the deposition of carbon deposits. Third, run more high speed and try to improve the shift speed of manual gear.

3. Using fuel cleaning protectant It is very simple to clean the engine with cleaning protectant. Please refer to the product manual for specific usage and precautions. Because the gum washed from the oil tank, the filter screen of the gasoline pump and the fuel pipeline will be deposited on the gasoline filter, the fuel filter (gasoline grille) must be replaced in time after disassembly and cleaning. It needs to be reminded again that the chemical cleaning components in the cleaning agent have a certain corrosive effect on the rubber oil supply pipeline. When using this method, we must pay attention to the service cycle and interval, otherwise it will accelerate the aging and corrosion of fuel rubber oil supply pipeline.
