Wear and Effect of Engine Piston Rings

1. The piston ring reciproes between the upper and lower dead centers, and the speed changes from a static state to about 30m/s, and so repeated large changes.

2. When doing reciproing motion, the cylinder pressure changes greatly during the intake, compression, work and exhaust strokes of the working cycle.

3. Due to the influence of the combustion stroke, the movement of the piston ring is often carried out at high temperature, especially the gas ring. Under the chemical action of high temperature, high pressure and combustion products, the oil film is difficult to establish, so that it can achieve complete lubriion. Difficult, and often in a state of critical lubriion.

Among them, the material and shape of the piston ring, the material and structure of the cylinder liner piston, the lubriion state, the structural form of the engine, the operating conditions, the quality of fuel and lubriing oil, etc. are the main factors. Of course, in the same cylinder, the influence of the lubriion state on the wear of the piston ring is the same, the state. The ideal lubriion between the ring surfaces is that there is a uniform oil film between the two sliding surfaces, but this situation does not exist in fact, especially the gas ring, due to the influence of high temperature, it is difficult to establish an ideal lubriion state.
