The wet engine cylinder liner breaks through the structural form of the traditional cylinder liner. The helical support radiator can firstly hoop the cylinder liner body, strengthen the cylinder liner body, and avoid deformation of the thinner cylinder liner body.
Before the cylinder sleeve is installed in the body, the water sealing ring should be coated with alkaline soap or neutral lubricant, which will lubricate the water sealing ring and the lower seat hole of the body when the cylinder is installed, so as to prevent the water seal from being damaged, rolled, and dislocated. and other abnormal phenomena;
The mechanism of cylinder damage is mostly due to the local damage of the lubricating oil film on the sliding part. At this time, metal contact occurs at the protruding parts of the two relatively moving surfaces, and then a small "burning" phenomenon occurs locally. The relative motion is torn apart again.
