汽车发动机润滑油的选用分析

摘要

润滑的目的在于减少机件的摩擦与磨损，跟据实验，消耗于发动机摩擦的功率占总功率的19％～23％。通过选用合适的润滑油，改善润滑状况，可提高机械效率和延长发动机寿命；同时在目前能源短缺、环境污染严重的情况下，对节约能源、改善环境污染具有十分重要的意义。%Lubricants intended to reduce friction and wear parts.Depending on the experimental data, the engine friction power consumption in the total power is from 19%to 23%.Appropriate choice of lu-bricants can improve lubrication conditions,increase mechanical efficiency and prolong engine life.On the condition of the energy shortages and environmental pollution situation,it is of great significance to save energy and improve environmental pollution.
