摘要
描述了近几年车用汽油机发展的几种新技术,包括GDI和HCCI燃烧技术以及混合动力技术的应用和发展,分析了它们的特点和在节能、环保等方面的作用。介绍了利用发动机排气余热的温差发电技术。论述了利用发动机冷却水余热和排气余热来改善发动机性能的新技术,该技术通过一套发动机后接蒸气动力装置,回收发动机余热能量做功,从而提高发动机能量利用率。探讨了这一新技术的研究内容,展望了它的应用发展前景。
The application and progress of the new technologies of vehicle gasoline engine developed in recent years is described, including GDI and HCCI technology, and hybrid Electric Vehicle, and their characteristics and effects on energy saving are analyzed. The power generation technology utilizing the temperature difference of engine exhaust gas is introduced. A new technology of improving engine performance utilizing waste heat from coolant and exhaust gas is introduced, by adopting a device of steam power cycle operating on the recovery of waste heat, and thus the energy efficiency of the engine is improved. The research content is explored and the foreground is prospected for the technology.
