发动机是车辆的重要部件,其主要的性能指标如动力性指标、经济性指标、排放性指标直接决定决定了整车的动力性、经济性、排放等级等重要性能。通过整车(三轴牵引汽车)的动力性和经济性要求来对柴油发动机的动力性指标和经济性指标进行讨论,以确定整车对发动机的匹配要求,以最大扭矩为基点展开讨论和分析。 The engine is an important part of the vehicle, its main performance indicators such as dynamic, economic, emission targets directly determine the vehicle’s power, economy, emission levels and other important performance. The dynamic and economic requirements of the diesel engine are discussed through the requirements of the power and economy of the vehicle (three-axle towing vehicle) to determine the matching requirements of the vehicle to the engine. The discussion and analysis are based on the maximum torque .
