改善润滑对汽车节能的影响及车用润滑油的发展趋势

Effect of Lubrication Improvement on Energy Saving and Development Tendency of Lubricant for Motor Vehicle

从减少汽车摩擦损失与降低燃油消耗率之间的关系出发，论述了实现润滑油低粘度化、高粘度指数（多级油）化、减摩性能最佳化和品质高档化等对汽车节能的影响，并简述了车用润滑油的发展趋势。

Begin from the ralation between frictional loss decreasing of motor vehicle and fuel consumption rate raducing,the article discourses the effect on motor.vehicle of the energy saving by means of lowering viscousity,raising viscousity index(multigrade lubricant),optimizing friction reduction property and promoting quality,etc of lubricant.It also briefly outlines development tendency of lubricant for motor vehicle.
