Editing and broadcasting of cylinder pulling faults

Causes and Prevention

Diesel engine cylinder pulling refers to the phenomenon of excessive wear, burrs, scratches, scratches, cracks, or bites on the working surface caused by the intense interaction between the piston components and the cylinder mating working surface (caused by friction). Cylinder pulling is the adhesive wear to varying degrees under lubrication conditions. When cylinder pulling is light, it causes damage to the cylinder liner and piston components, and in severe cases, it can cause a vicious engine damage accident of cylinder biting. When pulling the piston or connecting rod, it can damage the machine, Therefore, it is of great significance to analyze the formation mechanism of the diesel engine cylinder pulling fault, find out the early prediction and correct countermeasures, correctly manage and use the diesel engine, improve the reliability and extend the service life, and improve the management personnel's strain energy for troubleshooting. Reasonable use and attention to maintenance (regular inspection) can also reduce the diesel engine cylinder pulling fault

Cylinder liner is the full name for cylinder liner.

The cylinder liner is embedded in the cylinder block, forming a combustion chamber together with the piston and cylinder head. In the early water-cooled internal combustion engines, the cylinder liner and water jacket wall were cast as a whole, without a cylinder liner. The inner wall of the cylinder guides the piston directly, while the outer wall of the cylinder is cooled by cooling water.
