摘　　要：为通过降低润滑油黏度提高汽车燃油经济性,通过配制3款低黏度润滑油,利用发动机台架试验和整车燃油消耗试验对比了测试油0W20和参比油5W30对发动机燃油经济性的影响。结果表明:低黏度润滑油有利于提高发动机的燃油经济性,在试验车辆上的节油效果最高达1.28%;添加钼元素可以减少低黏化带来的抗磨性变差的问题。To improve vehicle fuel economy by reducing lubricant viscosity,3 low-viscosity lubricants are formulated,the effect of test oil 0W20 and reference oil 5W30 on engine fuel economy is compared by using engine bench tests and vehicle fuel consumption tests.The results show that the low-viscosity lubricant helps to improve engine fuel economy,with a fuel saving of 1.28%for this test vehicle;the addition of molybdenum reduces the deterioration of antiwear properties associated with low viscosities.
