The wear of gasoline engine block is divided into two parts, one is normal wear, the other is abnormal wear. The cylinder block manufacturers of gasoline engine will explain the wear of the two situations for you, and hope to help you.
The normal wear refers to the wear and tear of the engine in the allowable range of the cylinder, which is less affected.
1, abrasive wear: because of the air in the air mixed with dust, oil in the oil has carbon, metal debris and other foreign solid impurities, form abrasives, attached to the cylinder mirror, leading to the wear of the cylinder.
2, corrosion wear: the acid (such as C02, CO, S02) which occurs after the incineration of combustible mixture is associated with water vapor, which will corrode the metal of the cylinder surface. Under the conflict effect of the piston, the surface metal of the cylinder falls, that is to form corrosive wear.
3, melting wear: when the cylinder and the piston slip in a smooth and bad condition, both have a very small part of the metal to touch directly, the conflict constitutes a part of high heat, so that the melting touch, falling, gradually expanding that occurs wear, severe form of "cylinder".
The normal wear has the following trend: on the cylinder cross section today, because the inherent line of the piston skirt and the side pressure on the cylinder wall will form an ellipse, it is not easy to conform the oil film on the cylinder's longitudinal section because the upper cylinder is close to the burning chamber.
Abnormal wear is mainly caused by engine failure, resulting in serious wear.
1, the upper cylinder wear is severe: it is related to the inhalation of a lot of dust or severe carbon, should maintain or replace the air filter, clean up the carbon, and see if it is caused by oil channeling.
2, the cylinder bottom wear is serious: oil contains many metal particles or dust, should replace the cleaned oil.
3, the cylinder wear is severe in the middle: it is related to frequent corrosion and wear of engine undercooling and frequent cold start, so we should check the cooling system.
4, the first piston ring at the top stop is grim: the engine is overheated and the heat dissipation is not good. The cooling system, the incineration system (including the spark plug selection) should be viewed, and the other view connecting rod bearing is not loose.
After the cylinder wear, the cooperation void with the piston increases, which can form oil channeling, gas channeling, tighten pressure and dynamic deterioration, and also make up the cylinder, aggravating the wear of cylinder, piston and piston ring.
Although the two are different, they have an impact on each other. If they do not change to the specified number of years, they will also lead to normal wear to abnormal wear. This is a constant damage to the cylinder block of the gasoline engine, and the damage to the engine.
