摘　　要：空燃比是对发动机的工作和排放具有重要影响的指标。为此,本文在综合介绍国内外空燃比测量方法原理的基础上,着重对几种较新的测量方法空燃比传感器、离子电流及利用神经网络进行预测等进行了介绍,以期为空燃比测量提供参考思路。Air fuel （A/F） ratio may effect absolutely on performance and emission of an internal combustion engine, so the paper makes depiction with regard to its principle and methods of A/F ratio measurement that have been done home and abroad, in particular, to some new methods including the A/ F sensor, ion current and predication by neural network. It is expected to provide some means for A/F ratio measurement.
