根据过去工作的经验而整理出摩擦损失在发动机全部损失中所占的比例(见表1)。 表1是著名流体润滑理论学Pinkus和本、斯泰特大学的Klaus分别发表的摩擦损失比例数据,前者是EPA(美国环保局)市内和高速公路混合实车行驶试验测得的数据,由表1可知,每加入100份燃料的能量,得到的指示功为38马力,而输出功只有25马力,后者是车辆等速(80公里/小时)行驶时测得的数据。两者摩擦损失所占的比例相当接近。
Based on the experience of past work, we sorted out the proportion of friction losses in the total engine loss (Table 1). Table 1 is the friction loss data published by famous fluid lubrication theory Pinkus and Klaus of Bentet University respectively. The former is the data measured by the driving test of EPA (United States Environmental Protection Agency) Table 1 shows that for every 100 fuels added, it gives 38 hp and 25 hp, which is measured when the vehicle is traveling at constant speed (80 km / h). The proportion of friction loss between the two is quite close.
