摩托车和轻便摩托车燃油消耗标准的演变及新国标简介

对于采用等速法评价的标准，新标准燃油消耗量的测量和计算过程更加繁琐和复杂，但对摩托车燃油经济性评价更全面、科学，更接近于实际使用情况。实际上，在某些方面，旧版的燃油消耗量测量标准具有独特的优势，特别是在产品开发时，按旧版标准的方法绘制的燃油消耗曲线可以了解车辆在整个工作范围内具体的燃油消耗情况及变化趋势，旧版标准虽已作废，但标准中规定的试验方法还是可以借鉴的，企业自己对产品进行评价时，建议进行路试燃油消耗曲线和综合燃油消耗两方面的评价，这样开发出来的产品也会具有更好的燃油经济性。

The Evolution of the Standards for Fuel Consumption of Motorcycles and Mapeds and a Brief Introduction to the New National Standard

For the standard evaluated by adopting the constant speed method, the process of measuring and calculation of fuel consumption stipulated in the new standard is more complicated, but its evaluation is more comprehensive, scientific and real in terms of the fuel economy of motorcycles. Actually in some cases, the oldedition fuel consumption standard has more peculiar advantages, especially when developing products. If the fuel consumption curve is plotted according to the old standard, we can find out the specific fuel consumption of the motorcycle in its working range and the change trend. Although the old-edition standard has been invalid, the test method stipulated in it can be taken for reference. The manufacturers are suggested that they should evaluate both the road test fuel consumption and the integrated fuel consumption when evaluating products, so the product developed will be good in fuel economy.
