Abstract: This paper presents a principle and several kinds of typical construction of which gasoline injection system achieves layer-built combustion with gasoline. In recent years,some countries adopt layer-built combustion with gasoline in order to achieve high power, low fuel consumption and low exhaust pollution. It mainly points out how to achieve this goal in gasoline injection by electronic-control.

摘要： 本文介绍了用汽油喷射系统实现汽油机分层燃烧的机理及几种典型结构。当前,一些国家把汽油机采用分层燃烧作为实现高功率、低油耗、低排放的重要措施之一。文中着重指出用电控汽油喷射来实现这一目标。
