Experts say piston rings are the most important part of truck engines, and their work directly affects the engine work of trucks. If the piston ring is also easy to damage, the user of a truck usually changes the piston ring as the time limit for checking the engine.

The causes of engine wear of Baotou Bei Ben heavy truck accessories are:

1. the reciprocating motion between the engine piston ring and the upper and lower stop points, and the speed changes from static state to about 30m/s, so that the amplitude changes greatly.

2. when doing reciprocating motion, the cylinder pressure varies greatly in the intake, compression, work and exhaust stroke of the working cycle.

3. because of the impact of the burning stroke, the movement of the piston ring of the heavy truck parts in Baotou is often carried out at high temperature. Especially the first gas ring, the oil film is difficult to establish under the chemical action of high temperature and high pressure and burning product, so it is difficult to realize complete lubrication, and often in critical lubrication state.

There are many reasons for the wear of the piston ring of Baotou Bei Ben heavy truck fittings. These factors may be intertwined. The type and the use condition of the truck engine are different, and the wear of the piston ring of the engine is very different, so it can not solve the problem by improving the structure and material of the piston ring of the engine.
