汽车的燃料经济性由它的运行燃料消耗来确定。汽车的运行燃料消耗取决于多种因素,最主要的是车辆的技术状况,运行时的道路条件和气候状况,驾驶操作方法,吨位利用率和里程利用率等。汽车的技术状况良好与否,不能单凭其运行消耗来评定,而首先必须查明该汽车运行中有没有与其技术状况有关的超耗,因为,耗费工时、备件而去修理技术状况良好的 The fuel economy of a car is determined by its operating fuel consumption. The fuel consumption of a car depends on many factors, most notably the technical condition of the vehicle, the road conditions and climate conditions at the time of operation, the method of driving operation, tonnage utilization and mileage utilization. The technical condition of a car is good or not and can not be assessed solely by its operational expenditure, but first it must be ascertained whether there is any exorbitant expenditure on its condition in the vehicle’s operation because it takes a lot of man-hours and spare parts to repair a technically sound condition
