| 摘 要： | 根据不同经济性指标,对并联式气动-柴油混合动力发动机提出了相应的空气管理方案,并进行了数值仿真研究.计算结果表明:以气动缸最高效率为目标的优化方案适合在常规工况下使用;以最低气耗率为目标的优化方案可作为短时间、高负荷工况时的补充,而以两缸流量相等的方案不宜在该混合动力发动机中使用.此外还对柴油缸采用增压技术、改变两缸转速比等方案进行了探讨.

| Abstract: | In allusion to various economy indexes of parallel air-powered and diesel hybrid engine,corresponding air management precept was proposed.Numerical simulation results show that the precept which leads to the highest availability efficiency of air-powered cylinder is suitable for general operation condition,the precept which leads to the lowest air consumption is suitable for short-term and heavy-load operation,but the precept,in which two cylinders have the same air flow,is suitable for this type of hybrid ... |
