摘要：

为预测并联式气动-柴油混合动力发动机的性能,判断其可行性,建立了该混合动力发动机的工作过程理论模型并进行了数值仿真研究.结果表明,这种形式的混合动力发动机能实现其设计目的,即回收利用柴油缸排气废热以提升气动缸性能.在不对柴油缸工作造成明显负面影响的情况下,混合动力气动缸的动力性与经济性较纯气动缸均有较大幅度的改善.对整个系统而言,提高了能量利用率,减少了对矿物燃料的消耗.与纯气动缸的情况相似,混合动力发动机中气动缸在低转速、高负荷的工况下也有较好的性能,但可以避免纯气动缸在高转速工况下性能急剧恶化的现象.原理性论证实验的结果也证明了该混合动力的可行性.
Abstract:

A theoretical model of parallel air-powered and diesel hybrid engine's working process was established to predict the performance and judge the feasibility of the hybrid engine. Simulation results showed that the hybrid engine reclaimed the exhaust heat of diesel cylinder to improve the air-powered cylinder's performance. Power and economic characteristics of air-powered cylinder in hybrid engine were obviously enhanced without worsening the capability of diesel cylinder compared with working solely. Energy efficiency of the whole system was increased and fossil fuel consumption was reduced. The air-powered cylinder in hybrid engine performed well at lowspeed and heavy-load like working solely, but the phenomenon that power and economic characteristics exasperates rapidly with the increasing of engine speed can be avoided. The experimental study on principle also proved the feasibility of the hybrid engine．
