升功率是从发动机有效功率出发,对其气缸工作容积利用率的总评价。升功率值愈大则发动机的强化程度愈高,而发出一定有效功率的发动机尺寸愈小。因此,不断获得更强化、更轻巧、更紧凑的柴油机,是历来内燃机工作者所致力以求的奋斗目标。于是, Liter power is starting from the effective engine power, the overall evaluation of the cylinder capacity utilization. The higher the power value, the higher the degree of engine reinforcement, and the smaller the engine size that gives a certain effective power. Therefore, continuously obtaining a stronger, lighter and more compact diesel engine has always been the goal that the internal combustion engine workers have been striving for. then,
