汽油机闭环电控补气系统

A closed Loop and Electronic-Controlled Air Supplementary System in Gasoline Engine

为化油器式在用车达到排放法规介绍了一种汽油机闭环电控补气系统。着重分析和研究了系统的工作原理、组成结构和改装过程。 ＤＡ４６２、 ＤＡ４６２－ １Ａ和 ＤＡ４６５Ｑ－ １Ａ型发动机经改装补气系统后，分别安装在松花江、昌河和吉林微型车上，试验结果证实了该补气系统的可行性和实用性。

A closed loop and electronic - controlled air supplementary system in gasoline engine is described in this paper in order to meet the requirements of emission regulations for present - used carburetor type engine vehicles. The working principle, structure and modifying process of this system are placed emphasis on analysis and research. It is proved by test results that the air supplementary system has its feasibility and practicability after DA462, DA462 - 1A and DA465Q - 1A engines with a modified air supplementary system installed in Songhuajiang minicar, Changhe minicar and Jilin minicar respectively.
