项目摘要

This year, the fuel consumption of cargo truck was mainly investigated on transporting process. Hearing surveys to shipping companies could hardly get available data of the fuel consumption separately for back and forth. Using the data barely obtained for 16 trucks, we got the following formula of energy consumption as the function of overall weight of car and cargo. y = 36.2 x^<0.419>, R^2=0.80. Then, according to fuel consumption standards the formulae were obtained as shown below.For diesel truck with manual gear: y= 51.2x^<0.354>, R^2=0.99, with auto-gear: y=49.0x^<0.383>, R^2=0.94 For gasoline truck with manual gear: y=4.8x^<0.697>, R^2=0.96 and for gasoline own car: y=1.44x^<0.856>, R^2=0.97. Moreover, using 6 cars including van-type, the experiment of fuel consumption was carried out by changing the number of passengers. The following formulae were obtained,. For fuel-saving car: y=113x^<0.197>, R^2=0.96, or y=100x^<0.214>, R2=0.95, and for van-type car y=158x^<0.234>, R^2=0.79. Anyhow, it is not practical to consider that energy consumption is proportional to the overall weight of car. Therefore, in a case study to analyze the cost and energy consumption necessary for the transportation of all biomass waste in Yamaguchi prefecture to Ube city, the formula y=16.2x^<0.5>, R^2=0.74 using the data of above 16 trucks was used. Comparing the efficiency in cases that the number of chipping plants is decreased to 19, 13, 6 by order. By decreasing the number it becomes disadvantageous from the point of cost and energy consumption. The necessary energy to the transportation is in the range from 0.51% to 0.67%.

本年度，载货汽车的燃料消耗主要是在运输过程中进行调查。对航运公司的听证调查很难得到来回分开的燃料消耗的可用数据。利用16辆卡车的数据，我们得到了以下的能量消耗公式作为汽车和货物总重量的函数。y = 36.2 x^<0.419>，R^2=0.80。然后，根据燃油消耗量标准，得到了如下公式：对于柴油车，手动挡：y= 51.2x^<0.354>，R^2=0.99;对于汽油车，手动挡：y=49.0x^<0.383>，R^2=0.94;对于汽油车，手动挡：y=4.8x^<0.697>，R^2=0.96;对于汽油车：y=1.44x^<0.856>，R^2=0.97。此外，使用包括厢式车在内的6辆汽车，通过改变乘客人数进行了燃料消耗实验。得到以下公式，对于节油型轿车：y= 113 x ^<0.197>，R^2=0.96，或y= 100 x ^<0.214>，R^2 =0.95;对于厢式轿车：y= 158 x ^<0.234>，R^2=0.79。无论如何，认为能源消耗与汽车总重量成正比是不切实际的。因此，在分析山口县所有生物质废物运输到宇部市所需的成本和能量消耗的案例研究中，<0.5>使用了使用上述16辆卡车的数据的公式y=16.2x^，R^2=0.74。比较了削片厂数量依次减少到19、13、6时的效率。通过减少数量，从成本和能量消耗的角度来看是不利的。运输所需的能量在0.51%至0.67%的范围内。
