汽油机电控喷油系统空气流量的检测

Air flow measurement for electronic fuel injection system of gasoline engine

汽油机进气量的准确计量是其电控喷油系统实现空燃比精密控制的基础，文中系统综述了空气流量测量技术的国内外发展状况，对各种不同流量检测方式进行了对比分析，并提出了见解。

The accurate air-fuel rate control of electronic fuel injection system is based on ex act measurement of intake flowrate.In this paper,the developing situations of domestic and foreign air flowrate measuring technology are discussed,different inspection patterns are com pared and analyzed,and some personal views are put forward.
