Analysis of cost and energy consumption for venous trasportation

今年，货运卡车的油耗主要从运输过程中进行调查。对航运公司的听证调查很难获得往返燃料消耗的单独数据。使用16辆卡车勉强获得的数据，我们得到了以下能源消耗与汽车和货物总重量的函数公式。Y=36.2x^；0.419；，R^2=0.80.然后，根据油耗标准，得到如下公式：手动挡柴油货车：Y=51.2x^&lt；0.354；R^2=0.99；汽车挡：Y=49.0x^&lt；0.383；R^2=0.94.手动挡汽油车：Y=4.8x^&lt；0.697&gt；，R^2=0.96.汽油车：Y=1.44x^&lt；0.856&gt；，R2=0.97.此外，还利用包括厢式货车在内的6辆轿车，通过改变载客量进行了油耗试验。得到了下列公式：对于节油型轿车：y=113x^&lt；0.197；，R^2=0.96or y=100x^&lt；0.214；，R2=0.95.对于厢式轿车，y=158x^&lt；0.234&gt；，R^2=0.79。无论如何，认为能源消耗与汽车的总重量成正比是不现实的。因此，在分析山口县所有生物质废物运输到宇部城市所需的成本和能源消耗的案例研究中，使用了公式y=16.2x^&lt；0.5&gt；，R^2=0.74，使用上述16辆卡车的数据。比较了削片厂数量依次减少到19、13、6个的情况下的效率。从成本和能源消耗的角度来看，减少数量会变得不利。运输所需能量在0.51%~0.67%之间。

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%.
