摘要
针对城市公交车的交通特征,提出了五循环工况百公里燃油消耗量的经济性评价指标,并利用MATLAB软件编制了计算程序,对某城市公交车循环工况的燃油经济性进行了模拟计算。结果表明,四循环工况的模拟计算与试验结果相当吻合,验证了本文循环工况燃油经济性模拟计算方法的正确性;而五循环工况的模拟计算则与实际使用情况更接近,能更好地表征城市公交车的经济性能。
The paper establishes the evaluating index of fuel economy considering the city traffic environment, and the fuel consumption of 100 km in five circulation road conditions is presented. Then the program calculating the evaluating index of fuel economy is designed by MATLAB. The simulating results of four circulation road conditions are consistent with the road test. While the simulating results of five circulation road conditions are close to the practical use situation and could express city bus property better and effectively.
