拖拉机制造厂对本厂的新产品和变型产品都要作性能试验,试验中需要测定拖拉机在试验区段的油耗。但一般中小制造厂的试验设备都比较简陋,没有车用油耗自动测量仪。为了进行手扶拖拉机的性能试验,我们制作了一种容积式油耗计(图1)。 Tractor factory on the factory’s new products and modified products for performance testing, the test requires the determination of tractor fuel consumption in the test section. However, the general small and medium manufacturing plant test equipment is relatively simple, there is no car fuel consumption automatic measuring instrument. In order to conduct a performance test of tractor, we have made a volumetric fuel consumption meter (Figure 1).
