After the overloaded new piston ring is loaded into the cylinder, the piston ring is inflated by the impact and causes breakage without overloading the load, especially the impact load of the vehicle.
The impact fracture creates a step due to the wear of the top of the cylinder, and the piston ring breaks under the impact of the step.
If the piston ring gap is too small, the cracks will open top dead after thermal expansion, and the opposite side of the opening will form a fracture.
The ring groove coke causes the piston ring to break. Due to the hardening of the carbon deposit in the ring groove, the piston undergoes an axial alternating bending force to cause the piston ring to break.
The wear of the ring groove exceeds the limit, so that the piston ring is twisted in the ring groove. The fractured piston ring is subjected to additional twisting during operation, and the bending stress also causes the piston ring to break.
There is a problem with the quality of the broken piston ring material, there is an air gap during the casting process, the presence of sand holes can also cause the piston ring to break.
Locating Pin Damaged Piston Ring Broken Piston Ring (2-stroke diesel engine) with locating pin. If the locating pin at the opening of the piston ring is damaged, the hanging of the piston ring at the inlet and exhaust ports can also cause the cylinder or piston ring to break.
