摘要
本文分析了额外加入的燃料量对进入各缸的燃料及空气相对测量误差精度的影响,探讨了浓混合气极限下的测试方法。其结论是恰当地掌握加入的燃料量,选择燃料调整特性曲线上比较平稳的线段进行测量,对提高测量精度是有益的。
This paper analyses the influence of additional fuel quantity on relative measuring error of fuel and air quanlity entering into every cylinder. The conclusion is that: adding fuel in right quantity and selecting steady-state section of fuel-regulating characteristic for making the measuring are of benefit to improvement of the measuring accuracy.
