48 V车型燃料消耗量标准分析及试验研究
|
摘要
本文中对传统乘用车和混合动力乘用车燃料消耗量试验方法标准进行了分析,结合标准的有效性、适用性及其他国内外相关标准的具体内容,提出将48 V车型归为混合动力类型的建议。选取我国4款主流48 V车型进行燃料消耗量试验研究,首先结合发动机、电机的工作特性及试验过程中动力系统的能量输出/输入情况,对48 V系统的节能性进行了理论分析;综合4款车型的试验结果得出:48 V系统可使车辆燃料消耗量降低0.47 L/100 km,相当于节油6.48%。
This paper analyzes the standards of the test methods of fuel consumption of conventional and hybrid passenger cars. Based on the validity and applicability of the standards and other relevant standards at home and abroad, this paper puts forward the suggestion that the 48 V vehicles should be classified as hybrid electric vehicles. In order to carry on the fuel consumption experimental research, four mainstream 48 V models in our country are selected. Firstly, energy-saving of the 48 V system is theoretically analyzed according to the operating characteristics of the engine and the motor and the power output/input of the power system during the test. According to the test results of the four models, it can be concluded that the 48 V system can reduce the vehicle fuel consumption by 0.47 L/100 km, which is equivalent to fuel saving of 6.48%.
