【 摘 要 】

The free-acceleration smoke test method is widely used in diesel-powered vehicles or machinery to visually represent the level of particulate emissions from non-road mobile machinery. By controlling freely accelerated smoke emissions, particulate emissions from non-road mobile machinery can be effectively controlled. Based on the analysis of the working condition characteristics and particle generation principle of non-road mobile machinery, this paper has developed a method to optimize the non-road mobile machinery gear switching time to reduce the free acceleration smoke of the machine and achieved good results.
