Today, the editor of the automobile maintenance network briefly introduced to the friends the analysis of the reasons for the wear of the cylinder liner and the good maintenance methods. Engine cylinder liners and piston rings are a pair of friction pairs that work under conditions of high temperature, high pressure, alternating load and corrosion. Working under complex and changeable conditions for a long time, the result is that the cylinder liner wears and deforms, which is related to the engine's power, rationality and service life. Now, let the editor of the auto repair network briefly introduce to the friends the analysis of the reasons for the wear of the cylinder liner and the good maintenance methods!

Analysis of the causes of cylinder liner wear and good maintenance methods: causes

When the engine is cold-started, because of the low temperature, the viscosity of the engine oil is high, and the fluidity is poor, which makes the engine oil pump insufficient. At the same time, the engine oil on the original cylinder wall flows down the cylinder wall after stopping, so it cannot get such good lubrication during normal operation at the moment of starting, which greatly increases the wear of the cylinder wall during starting. Therefore, when starting for the first time, the engine should be idled for a few revolutions, and then start after the friction surface is lubricated. After starting, the engine should be turned at idle speed to heat up. It is strictly forbidden to blast the oil port. When the engine oil temperature reaches 40℃, then start; at the beginning, you should stick to the low gear and drive in each gear for a period of time until the oil temperature is normal. Drive normally.
