摘　　要：为进一步提高"柴油-天然气"双燃料汽车的经济效益和环境效益,基于6105型柴油机,通过改进燃烧室,增加点火系统,优化配气相位,开发混合系统、判缸信号发生器等,将柴油机改造为纯天然气发动机,并进行试验.结果表明:本设计采用压缩比10.5、气门重叠角10°时的发动机性能指标最优,且全面达到了委托企业所要求的性能指标.In order to further improve the environmental and economic benefits of diesel-CNG dual fuel vehicles, based on the 6105 diesel engine, a single fuel gas engine was developed through making some changs in the combustion chamber, improving the ignition system, optimizing valve timing, and developing a natural gas fuel mixture system and a signal gen- erator assembly. The results of the experimental study show that the performance of the new engine is optimal when the compression ratio is 10.5 and the valve overlap angle is 10~. Under these conditions, all the performance indexes can be reached.
