发动机的重要特性参数之一就是燃料消耗。通常它以每小时公斤数表示。因此,测量燃料消耗量就是测量一台发动机消耗一定容积的或一定重量的燃料所需的时间。由时间及燃料容积或燃料重量计算的油耗如下式: B=m/t (43) B=燃料耗量 m=燃料重量 t=测量时间 由容积计算燃料重量的公式如下: m=ρV (44) ρ=燃料比重 V=燃料容积
One of the most important characteristics of the engine is fuel consumption. It is usually expressed in kilograms per hour. Therefore, measuring fuel consumption is the time it takes to measure a single engine that consumes a certain volume or weight of fuel. The fuel consumption calculated from time and fuel volume or fuel weight is as follows: B = m / t B = fuel consumption m = fuel weight t = measurement time The formula for calculating the weight of fuel from the volume is as follows: m = ρ = fuel specific gravity V = fuel volume
