Measures to reduce cylinder liner wear	1. Correct starting and starting When the engine starts cold, due to low temperature, high oil viscosity, and poor fluidity, the oil pump supplies insufficient fuel. At the same time, the oil on the original cylinder wall flows down along the cylinder wall after parking, so it does not receive the same good lubrication as normal operation at the moment of starting, resulting in a significant increase in cylinder wall wear during starting. Therefore, when starting for the first time, the engine should be idle for a few laps until the friction surface is lubricated before starting. After starting, the engine should run at idle speed to warm up, and it is strictly prohibited to bang the oil port. Start again when the oil temperature reaches 40 ℃; You should stick to low-speed gear when starting, and drive a certain distance in each gear in sequence until the oil temperature is normal before switching to normal driving. 2. Correct selection of lubricating oil It is necessary to strictly select the best viscosity lubricating oil according to the season and engine performance requirements. It is not allowed to purchase inferior lubricating oil at will, and the quantity and quality of lubricating oil should be regularly checked and maintained. 3. Strengthen the maintenance of the filter Maintaining good working condition of the air filter, oil filter, and fuel filter is crucial for reducing wear on the cylinder liner. Strengthening the maintenance of the "three filters" is an important measure to prevent mechanical impurities from entering the cylinder, reduce cylinder wear, and extend the service life of the engine, especially in rural and windy and sandy areas. It is absolutely wrong for some drivers to not install air filters in order to save fuel. 4. Maintain normal engine operating temperature The normal operating temperature of the engine should be between 80-90 ℃. If the temperature is too low and good lubrication cannot be maintained, it will increase the wear of the cylinder wall. The water vapor in the cylinder is prone to condense into water droplets, dissolve acidic gas molecules in the exhaust gas, generate acidic substances, and cause corrosion and wear of the cylinder wall. Experiments have shown that when the temperature of the cylinder wall drops from 90 ℃ to 50 ℃, the wear of the cylinder is four times that of 90 ℃. If the temperature is too high, it will reduce the strength of the cylinder and intensify wear, and may even cause the piston to expand excessively, resulting in a "cylinder expansion" accident. 5. Improve warranty quality During use, promptly identify and eliminate problems, and replace or repair damaged and deformed parts at any time. When installing the cylinder liner, it is necessary to strictly inspect and assemble according to technical requirements. In the warranty ring replacement operation, it is necessary to choose a piston ring with appropriate elasticity. If the elasticity is too small, it will cause gas to enter the crankcase and blow off the oil on the cylinder wall, increasing the wear of the cylinder wall; Excessive elasticity directly exacerbates the wear of the cylinder wall, or exacerbates its wear due to the damage of the oil film on the cylinder wall. The crankshaft connecting rod journal and the main journal are not parallel. The engine may deform the crankshaft due to severe impact caused by burning tiles and other reasons. If not corrected in time and continued to be used, it will also accelerate the wear of the cylinder liner.
