摘要/Abstract

摘要： 分析了2000—2009年来中国汽车工业发展和与此相关的能源及排放法规的变迁，指出节能的重要性将会超过排放污染问题。缸内直喷汽油机(GDI)和小排量是目前汽油机节能的两条途径，在气道喷射式汽油机上采用小排量技术具有成本低的特点，而在GDI汽油机上采用小排量技术则可以获得更显著的节油效果。以均质当量比为特征的第二代GDI节油效果有限，第三代GDI必须解决爆震（高压缩比）、废气稀释燃烧稳定性以及微粒排放3个关键问题。均质压燃(HCCI)是汽油机节能减排理想的燃烧方法。汽油-柴油双燃料燃烧方式具有最高的节油效果，并为未来汽油机和柴油机的统一化奠定基础。

Abstract: This paper illustrates the development of Chinese automotive industry and the evolvement of related energy and emission regulations in the decade 2000—2009. It points out that the importance of energy-saving will exceed the problem of pollution. Gasoline direct injection (GDI) and downsizing are the main two approaches for low fuel consumption.The downsizing technology for port fuel injection (PFI) gasoline engines has an advantage of low cost, while the downsizing technology for GDI engines has a better fuel economy. The 2nd generation of GDI engines with stoichiometric combustion has a limited potential of low fuel consumption. The 3rd generation of GDI engine should solve three problems, including knock at high compression ratio, combustion stability in exhaust diluted atmosphere, and particulate matters formation in stratified mixture. Homogeneous charge compression ignition ( HCCI) is an ideal combustion mode for energy-saving and emission reduction of gasoline engines. Gasoline/diesel dual-fuel combustion can reach the highest benefit on fuel consumption, providing the possibility for unification of gasoline engines and diesel engines in the future.

Key words: gasoline engine, combustion, , high efficiency, low emission, gasoline direct injection (GDI), homogeneous charge compression ignition ( HCCI)
