【摘要】 本文提出了一种提高天然气汽车动力性能的方案,设计了控制系统及其执行部件,从汽油的加浓量、加浓点、减气点、点火提前角度等方面进行了优化试验研究,在保持天然气燃料良好排放性与燃料经济性的情况下,使天然气发动机的功率由原来不足汽油发动机功率的80％提高到95％以上。更多还原

【Abstract】 In the paper, a new scheme is brought forward for increasing the dynamic performance of natural gas automobile. A control system and It’s executive assembly is designed. In order to optimize the performance,such aspects,as quantity and timing of complementarity gasoline .reducing timing of natural gas , ignition timing are researched. On the basis of keeping the exhaust emission and economy performance, the engine power is improved from 80% to 95% of that one’s running on the gasoline fuel.更多还原
