When does engine oil need to be cleaned up immediately?

Analysis of the situation that carbon deposits need to be removed immediately

When the engine was burning oil for inspection, the last article said why many riders chose the method of cleaning up carbon deposits on the spot, and why it was not advisable to clean up carbon deposits on the spot. This article talks about under what circumstances it is necessary to clean up carbon deposits immediately.

When checking the oil, it is found that the cylinder has too much carbon deposit or other damage, and the carbon should be removed immediately.

The first situation is as follows.

The carbon deposit of the engine at the top of the piston has become a state of broken foam, which is distributed between the cylinder wall and the piston. More and more carbon deposits will accumulate in the marginal areas. If it is not treated and cleaned immediately, black stripes may appear on the cylinder wall.

The second situation is as follows.

The second situation is more serious than the first. The broken foam of carbon deposit has sunk to the middle area of gas ring or oil ring, and black vertical bars have been ground near the lining. In this case, the carbon deposit should be cleaned up immediately to prevent secondary and more serious strain.

Methods of removing carbon deposits

Static ice, pulse ice or dry ice are widely used in the market. It is suggested that dry ice is not used to remove carbon, and dynamic and static carbon removal methods can be used. If you want to use the fastest method, add PNF technology repair agent to the fuel tank, and most of the carbon deposits will be cleaned up after opening a box of oil.

If the cylinder wall is found to have very serious serrations or traces caused by metal friction during inspection, it is recommended to directly choose a repair shop for overhaul. Because this situation belongs to the piston liner and cylinder wall, serious wear has occurred. Most of this wear is caused by engine oil. It may be that the oil change cycle is too long, or the oil used is not good, or the oil is constantly replenished in the oil for a long time, resulting in intensive metal bite wear between the group lining and the piston. This kind of wear can't be solved by a mending agent.

To sum up, if there is carbon deposit in the cylinder when checking the oil, it can be handled in two ways. One is that there is a slight carbon deposit between the cylinder wall and the piston, but there is no black vertical bar strain, and the other is that black vertical bar strain has occurred. Both cases should be dealt with immediately. The treatment method can be static and the fuel tank can be filled dynamically. Using PNF repair agent can remove carbon deposit and effectively avoid secondary injury.
