汽车使用诸因素对燃油经济性的影响分析与试验研究

Analysis and Experimental Research of Influence of Automobile Usage Factors on Fuel Economy

结合科技文献理论,从气象条件、道路状况、驾驶行为等各个方面详细分析了使用因素对汽车燃油经济性的影响,并且通过大量气象条件和道路状况试验,对汽车燃油经济性的影响进行了定量的研究。得出汽车使用诸因素中环境条件、道路状况和驾驶行为对汽车燃油经济性的影响不可低估。温度对汽车燃油经济性的影响并不是简单的比例关系,环境温度高于常温时,温度对于汽车的影响相对比较稳定,而高温与低温的油耗相比相差悬殊。环境温度为-10℃时和常温相比,其燃油消耗量增加竟高达45%,在不同道路类型中,汽车在省级公路上行驶最省油,不同的道路条件对燃油经济性的影响高达30%,不同的驾驶行为对燃油消耗量也能产生高达20%的影响。

Consulting a lot of literatures, the influence of automobile usage factors （weather, terrain, driving style, etc. ） on fuel economy was analyzed.The influence of weather, terrain and road condition on fuel economy was quantitative studied by a lot of tests. It is concluded that （1） the usage factors for fuel economy are all important; （2） the influence of temperature on vehicle fuel economy is not simply proportional, when the ambient temperature is higher than normal temperature, the influence of temperature on automobile is relatively stable, high -temperature and low-temperature fuel consumption are greatly different; （3） at ambient temperature of - 10 ℃, fuel consumption increases as high as 45 percent compared with that of normal temperature; （4） in different types of road, the fuel consumption on the provincial road is the most efficient, the influence of different road conditions on fuel economy is as high as 30 percent, and the different driving behaviours can also generate up to 20% of the affection.
