高效燃烧汽油机技术特点分析与研究

参照近代内燃机技术手段可知,采用阿特金森循环等传统降油耗技术手段往往伴随着发动机动力性能的妥协,因此寻找一种兼顾动力性与经济性的提升热效技术手段变得迫在眉睫。阐述了马自达SKYACTIV-X、现代起亚Smartstream 1.5 L Turbo GDI等高热效汽油机技术路线的原理、结构形式、技术特点,为日后研发工作指明了方向。

Research on Technology Features of High Efficient Gasoline Engine

With the regulation about fuel consumption is being rigorous,the requirements for energy saving and emission reduction are continuously improved,the pursuit of higher thermal efficiency of gasoline internal combustion engine is the main theme of technology development recent years in automotive industry.The traditional means of reducing fuel consumption,however,such as Atkinson cycle,are often accompanied by the compromise of engine power performance.Therefore,it is urgent to find a kind of technical means of improving thermal efficiency that gives consideration to both power performance and economy.This paper describes the principle,structure and technical features of Mazda SKYACTIVX,Hyundai-Kia’s Smartstream 1.5 L Turbo GDI Engine and other high-efficiency gasoline engines,and points out the direction for future research and development.
