摘要
针对新型天然气发动机性能的要求,研究天然气发动机主要技术特性,分别分析活塞顶面、环岸及环槽、销孔以及其他部位与柴油机活塞异同,设计了满足天然气发动机性能要求的活塞。利用有限元分析方法,对设计方案进行分析和评价。通过2 000 h耐久试验和20万公里路试验证,得出设计结论。
According to the requirement of new type natural gas engine, we have researched on the main technical features of natural gas engine. This paper analyzes the similarities and differences from diesel engine piston at piston crown, ring lands and ring grooves, pin hole and other parts of piston respectively. Piston in accordance with natural gas engine performance has been designed. Using FEA method, we have analyzed and evaluated the design scheme. Through 2 000 h durability test and 200 000 kilometers road test, it comes to the design conclusion.
