The correct maintenance of the cylinder liner

'Cylinder' set of correct maintenance methods. Strengthen the maintenance of the air filter, oil filter, filter and fuel filter to keep good work condition, to reduce the cylinder liner wear is very important. To strengthen the maintenance of '/', is to prevent the mechanical impurities into the cylinder, lighten the cylinder wear, prolonging the service life of the engine is an important measure, and more sand area is especially important in the countryside. Some drivers in order to save fuel and not installed air filter is absolutely wrong. 。 Correct selection and use of lubricating oil must be strictly according to season and engine performance requirements to choose the best value of the lubricating oil viscosity, should buy with inferior oil, and regularly check and keep the quantity and quality of the lubricating oil. 。 Maintain the normal work of the engine to normal operating temperature should be in ℃ temperature. Temperature is too low, can't keep good lubrication, will increase the wear of cylinder wall, inside the cylinder of water vapor condenses into water droplets, dissolve acidic gas molecules in the exhaust, and generate acid, corrosion and wear to the cylinder wall. Tests show that when the temperature of the cylinder wall to by ℃ ℃, for the cylinder wear ℃ at times. Temperature is too high, can make the decrease of strength of cylinder and increased wear and may even make the piston bloated 'cylinder' inflation caused by accidents. 。 The correct starting and start engine cold starting, because of the low temperature, oil viscosity, liquidity is poor, shortage of lubricating oil in the oil pump. Oil at the same time, the original cylinder wall after parking along the cylinder wall dirty, so when starting moment is not working as good lubrication, starting when the cylinder wall wear is greatly increased. Starting for the first time, therefore, should make the engine idling around, after being friction surface for lubrication and starting again. Should be idle running after starting to heat up, it is strictly prohibited to fierce boom oil mouth, for the oil temperature reaches ℃ to start; Start should stick to hang low gear, and each gear driving a mileage, step by step until the oil temperature is normal, can into normal operation. 。 Improve the quality of the warranty in use process, timely find problems in a timely manner to eliminate, replace or repair damage and deformation of the parts at any time. Installing a jacket to technical requirements in strict accordance with the inspection and assembly. During the warranty in ring operations, should choose elastic proper piston ring, the tension is too small, fall into the crankcase blow cylinder wall of the oil gas, increase the cylinder wall wear and tear; Tension is too large, directly add to the cylinder wall wear and tear, or because of the oil film of cylinder wall is destroyed and aggravate the wear and tear.
