Engine Cylinder Liner for Toyota 2KD Europe Truck

The working environment of the cylinder liner is very bad, and there are many reasons for wear. Normal wear is usually allowed due to structural reasons, but improper use and maintenance will cause abnormal wear.

1.Wear caused by structural reasons

1) The lubrication condition is not good, so that the upper part of the Cylinder Liner wear seriously. The upper part of the cylinder liner is adjacent to the combustion chamber, the temperature is very high, and the lubrication condition is very poor. The erosion and dilution of fresh air and unevaporated fuel aggravate the deterioration of the upper condition, so that the cylinder is in a state of dry friction or semi-dry friction, which is the cause of serious wear on the upper cylinder.

2) The upper part is under large pressure, so that the cylinder wear is heavy on the upper and light on the lower. The Piston Ring is pressed tightly on the cylinder wall under the action of its own elasticity and back pressure. The greater the positive pressure, the more difficult the formation and maintenance of lubricating oil film, and the worse the mechanical wear. In the work stroke, as the piston goes down, the positive pressure gradually decreases, so the cylinder wear is heavy up and light down.

3) Mineral acids and organic acids make the cylinder surface corroded and spalling. After the combustion of the combustible mixture in the cylinder, water vapor and acid oxides are produced, which dissolve in water to produce mineral acids, plus the organic acids generated in the combustion, which have a corrosive effect on the surface of the cylinder, and the corrosive substances are gradually scraped off the piston ring in the friction, resulting in cylinder liner deformation.

4) Enter the mechanical impurities, so that the middle of the cylinder wear. Dust in the air, impurities in the lubricating oil, etc., enter the piston and cylinder wall causing abrasive wear. When dust or impurities reciprocate in the cylinder with the piston, the movement speed is the largest in the middle of the cylinder, which aggravates the wear in the middle of the cylinder.
