摘　　要：对由S195柴油机改装得到的燃用变组分煤层气发动机进行了全面的测试和分析,包括缸内示功图、燃烧放热率、主燃期、点火提前角、火焰发展期以及最大压力循环波动等。结果表明:甲烷浓度、点火提前角、负荷的大小对火焰发展期、循环波动以及燃烧有着至关重要的影响。An engine fueled with coal -bed gas and ignited by spark is developed. The measurements for the prototype engine are thoroughly made, including the cylinder pressure, the rate of heat release, combustion duration, ignition delays, spark ignition angle, and the fluctuation of the cylinder maximum pressure. The results show that the methane concentration, the load, and the spark ignition angle will influence the cylinder maximum pressure~ variation, the combustion duration and the combustion.
