What is the effect of more carbon deposition in Fit?

If the engine burns engine oil, or the quality of gasoline is poor and there are many impurities, the valve carbon deposit will be more serious and form faster. Because the structure of carbon deposit is similar to sponge, when the valve forms carbon deposit, a part of the fuel injected into the cylinder will be adsorbed every time, which will dilute the concentration of the mixture that really enters the cylinder, resulting in poor engine operation, difficult starting, unstable idle speed, poor acceleration, sudden refueling and tempering, excessive displacement and increased fuel consumption.

There are many kinds of engine cleaning projects, such as cleaning the carbon deposit in the engine (lubrication system), cleaning the carbon deposit in the engine fuel system and cleaning the scaling in the cooling system. Cleaning the engine mentioned in many 4S shops mainly refers to cleaning the fuel system and lubrication system.

1. Now most automobile lubricating oils have their own cleaning function, which can ensure that the engine does not produce sludge or a small amount within a certain kilometer.

2. There is absolutely no need for deep engine cleaning when the new car is under warranty, which will cause great waste.

3. Corrosive cleaning agents will corrode non-metallic parts in the engine, leading to engine failure.

4. At the same time, the interior will wear and tear with the passage of time, and the internal sludge will play a certain role in making up and repairing.

5. If the driving mileage is long, cleaning the engine will reduce the oil pressure and the cylinder gasket will leak, causing great losses.

6. Cleaning the lubrication system, air intake, combustion chamber and other items is necessary to maintain the automobile engine, but it will generally be considered in 30,000-50,000 kilometers under the normal use of the vehicle.
