在 A.Jante 的著作[1]、[2]中指出了发动机的燃油消耗率 be(克/千瓦小时)和汽车的行驶阻力 Fw(牛顿)如何影响定距离平均燃油消耗量β_K(升/百公里)。以[2]中的等式(432—6)和(442—4)为出发点,如图1所示导出基本公式(e)。图2和图3分别以ρ_B=O.8333公斤/分米~3。的柴油发动机燃料(DK)和 P_B=O.73公斤/分米~3的化油器式发动机燃料(VK)为例表示出基本公式(e)中各参数之间的关系。粗实线表示求值的一个实例。当然,从图上不仅可以查出已知 be 和 F_W时的定距平均燃油消耗量,还可以求出给定
In A. Jante’s work [1], [2] it is pointed out how the engine’s fuel consumption be (g / kWh) and the vehicle’s driving resistance Fw (Newton) affect the average distance from the fuel consumption β_K Km). Starting from Equations (432-6) and (442-4) in [2], the basic formula (e) is derived as shown in FIG. Figure 2 and Figure 3 respectively ρ_B = O.8333 kg / dm ~ 3. Shows the relationship between the parameters in the basic formula (e) as an example of the diesel engine fuel (DK) and the carburettor fuel (VK) with a P_B of 0.73 kg / dm3. Thick solid line represents an example of evaluation. Of course, not only can be found from the map known be and F_W when the distance average fuel consumption, but also can be given given
