油液品质对发动机燃油经济性影响的试验研究

Experimental Study of Influence of Fuel and Oil Quality on Engine Fuel Economy

燃油经济性是车辆使用过程中的重要经济指标。为此,分析了发动机节油原理和节油途径,并通过实车试验的方法,研究了油液品质对燃油经济性的影响,提出了提高车辆燃油经济性的使用操作规程。试验表明,在不同的使用条件下,选用合适的燃油、润滑油以及各类添加剂,对降低发动机的燃油消耗具有明显效果。

Fuel economy is an important index evaluating the performance of vehicle. Principle and method of economizing gasoline were analyzed .At the same time, the influence of fuel and oil quality on fuel economy was studied through real-vehicle experiments. Operating procedure of promoting fuel economy was proposed. It shows that the fuel consumption of engine can be reduced effectively by selection proper fuel, oil and various additives in different using conditions.
