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.
Too low fuel injection pressure, fuel dripping from the injector, poor atomization of fuel injection, and too late fuel supply time will all cause poor fuel combustion and cause cylinder knocking. The knocking sound caused by this type of failure is low and hoarse, accompanied by engine overheating, black smoke or exhaust pipe firing, fire and other phenomena.
