小功率段多缸柴油机的发展和对策

The development and countermeasures of the small power multi-cylinder diesel engines

介绍国内外37kW以下的小功率多缸柴油机产品的发展;分析总结了国外小功率多缸柴油机产品的结构特点,阐明了我国小功率多缸柴油机产品现状、发展受限的原因,指出了随着非道路柴油机排放法规的不断加严,我国需要研发生产结构紧凑、节能环保的高性能小功率多缸柴油机产品,以满足国内外市场需求。依据中国目前行业现状,结合作者多年在小功率柴油机研发的经历,给出了开发小功率多缸柴油机需注意的问题、技术对策,对我国小功率多缸柴油机的发展提出了建议。

This article introduces the development of domestic and foreign small power multi-cylinder diesel engines which are below 37kW. It analyzes the structural characteristics of foreign products and clarifies the status of domestic small power multi-cylinder diesel engines as well as the causes which limit their development. It also points out that with the tightening of the emission regulations of non-road diesel en-gines, We need to develop high-performance small power multi-cylinder diesel engines which are compact, energy saving and environmental friendly to meet market demands at home and abroad. Based on the status quo of the domestic industry in combination with author＇ s many years＇ experience in research and development of small power diesel engine, it illustrates the development problems of small power multi- cylinder diesel engines that deserve our attention and the corresponding technical countermeasures, and provides recommendations on the development of the domestic industry.
