柴油机是目前世界上能量消耗最经济的动力机械,因此,在工程机械中获得极其广泛的应用。但是,柴油机的主要缺点是排气中有较多的微小碳烟粒子,污染周围环境。因此,排烟特性是内燃机极其重要的特性之一。随着柴油机性能不断强化,控制烟度已成为一个越来越迫切的课题。 Diesel engine is currently the world’s most energy-hungry power machinery, therefore, in construction machinery has been extremely widely used. However, the main disadvantage of diesel engines is that there are more tiny soot particles in the exhaust gas that pollute the environment. Therefore, the smoke characteristic is one of the most important characteristics of the internal combustion engine. With the continuous enhancement of diesel engine performance, the control of smoke has become an increasingly urgent issue.
