Continual Measurement and Analysis of Exhaust Composition of a Gasoline Engine

  • 摘要: 测量并分析了点燃式发动机起动、加速及若干稳定工况运行时排气中CO2、CO、HC、NO、O2的体积成分.结果表明:在发动机起动时,CO排放曲线上有一个峰值存在,在加速时,有一个峰谷存在;在排气的各成分中,HC的变化幅度较大;在发动机处于宏观稳定工况时排气中各成分亦呈现出一定波动.CO2、CO、HC、NO、O2的波动系数的变化分别为0.007~0.020、0.049~0.288、0.l~0.883、0.03~0.077、0.024~0.123.
    Abstract: The volumetric component of CO2, CO, HC, NO and O2 in exhaust of spark ignition engine was continually measured and analyzed under the condition of its starting, acceleration, and some steady modes. The results show that: (l) There is a peak value on the curve of CO emission at the starting of engine. (2) The variation of HC is the largest among the exhaust compositions. (3) The coefficients of CO2, CO, HC NO and O2 present a proper order, which are sequently 0.007-0.020, 0.049-0.288, 0.1-0.883 0.03-0.077 and 0.024-0.123, while engine is in steady operating mode macrographically.
