ing broken Broken piston ring stuck in the ring tank, will ring to lose flexibility, speed up the cylinder liner wear and tear, causing pulling cylinder. Caused by broken ring stuck due mainly to ring the opening gap is too small, the deflection piston in the cylinder, burning bad, so often in the engine running under deflagration conditions. Deflagration of the highpressure vibrating ring impact than the material impact strength, caused by broken piston rings. Its breaking generally occurs in the first ring, followed by the second ring. Stuck piston ring is due to bustiongenerated carbon deposition, particularly in channeling oil or dust, debris and other plug in between the piston and ring groove, so that piston rings stuck in the ring slot due. In addition, piston, piston rings, cylinder liner quality and materials on the pullcylinder also has a certain impact. 7 of measures to prevent the engine cylinder scoring and drivers to strictly observe the operational procedures Starting before they are required inspection of lubricating oil, cooling water to check for pliance, required to make up for insufficient check to determine whether the deterioration oil, lubricating oil is milky white water is generally caused by thinning and lubricating oil shows a diesel smell into the diesel oil, lubricating oil deterioration causes should be identified, removed, replace the oil. To strictly enforce the maintenance of the system, scheduled for cases of insurance, maintenance and a maintenance 2. Do not overload operation. Meng did not start after refueling door, especially in the cold winter, subject to a few minutes and then started to run lowspeed operation. The event of unusual circumstances, such as low oil pressure, water temperature high, abnormal noise, etc., should be promptly removed, insisted on not sick job. In the repair of assembly, it should be strict pliance with technical standards and technological requirements Spare parts for new ones to be used to detect one by one, to remove nonpliant spare parts to go out and can not believe that the new product is qualified product. Install cylinder, the cylinder should be flat, the pressure to the role of the middle of the cylinder, and slowly pressurized, do not use impact. After you install, testing, testing whether the cylinder and piston assembly clearance gap meet the required standards. Similarly, the detection of piston ring and groove side clearance, backlash, piston ring end gap and piston pin hole with live seat assembly clearance pliance with regulatory requirements, check whether there are cracks as well as the piston ring elastic pliance requirements, install a good Central, can be freely, without catching the phenomenon. Piston Ring Gap 3 (terminal gaps, backlash, backlash) in check is the piston rod assembly of a focus group, in particular the endgap size is particularly important at the slightest mistake could result in pullcylinder, ring end gap of the inspection should carried out according to process requirements, check the piston ring end gap of the process requirements are: the ring into the cylinder, the piston ring with the piston at the top of the roof into the cylinder where the top ring to the piston stroke measured at the smallest diameter, so that measurement data are correct. Carefully check the piston, connecting rod and crankshaft installation position deviation, demand technical specifications that meet standards for calibration. In the market to buy the piston, is hard to determ
