柴油机三高环境下性能提升技术研究现状与展望

摘要

概括了柴油机在三高环境下性能提升技术的国内外研究现状,主要分为高原高寒环境下采取的关键技术和高温环境下采取的关键技术两部分来综述概括.对于柴油机的高原高寒环境适应性的关键技术,研究重点在于增压技术、燃烧优化技术、低温起动技术、富氧燃烧技术等.对于柴油机的高温环境适应性的关键技术,常采用一些增加散热的措施.最后,针对国内外研究现状,对未来发展趋势进行了展望.%This paper summarizes the domestic and foreign research status of diesel engine technology at High/Low Temperature and at Plateau.It is divided into two parts:the key technologies taken in high altitude environment and the key technology in high temperature environment.For the key technology of adaptability to high altitude environment,they include supercharging,combustion optimization,low temperature starting,oxygen-enriched combustion and so on.For the key technology of adaptability to high temperature environment,it often increases cooling.Finally,the future development trend is forecasted in view of the current research situation at home and abroad.
