The twisted ring is a ring formed by cutting off a part of the inner edge of the rectangular section of the garbage truck or the lower edge of the outer circle. This ring is attached to the cylinder and is caused by the asymmetric distribution of the internal stress of the ring. The ring body is slightly distorted and deformed, so that the edge of the ring is in contact with the upper and lower end surfaces of the ring groove, the surface contact stress is improved, the pumping effect caused by the piston ring oscillating up and down in the ring groove is prevented, and the sealing performance is increased simultaneously. It is characterized by the fact that when the piston is subjected to changes in the side pressure, it is observed along the longitudinal direction of the engine. The outer surface of the barrel-shaped ring is a convex circular arc. Its feature is that it can form a wedge-shaped space with the cylinder wall of the detachable garbage truck when it moves up and down, which is conducive to the formation of a lubricant film. The arc between the ring surface and the cylinder wall is Surface contact, can well adapt to the piston's swing, and the contact surface is small, the sealing performance is good, the engine oil is discharged, the oil pan, the oil pump filter and the main bearing cover reinforcing plate are removed, and the pencil or quick-drying paint is used at all The cylinder number is marked on the piston, connecting rod and connecting rod cover, the connecting rod cover is removed, and the rubber sleeve is attached to the screw of the connecting rod bolt. When removing the connecting rod, the thread of the detachable garbage truck journal bearing and the connecting rod bolt is prevented from being damaged. Before removing the piston from the cylinder, the coke at the upper end of the cylinder is removed, the piston and the connecting rod are pushed out from the upper end of the cylinder, and the piston is used. Ring expander, remove the two compression rings and scraper ring from the piston, remove the piston ring from the connecting rod, carefully loosen the piston ring retainer, press out the piston pin, use appropriate tools, the piston head and piston The carbon deposit on the ring groove is washed away. Before the inspection, the piston ring groove must be clean, dry and free from coke, and the piston ring should be installed in the ring groove.
