摘　　要：针对高压共轨燃油喷射系统在柴油转子发动机上的应用,对直接喷射层状充气式柴油转子机的相关燃油及燃烧系统进行了专门设计,开发了新一代的集高压共轨燃油喷射控制等功能于一体的电子控制单元,进行了初步的运行试验。着重讨论了主、引双喷油器结构结合高压共轨燃油喷射系统在柴油转子发动机上的应用策略和实现方法。当前原理样机可以在高达6 000 r/min下平稳运行,4 000 r/min时单缸功率达到30 kW。试验表明:通过高压共轨燃油喷射系统结合合理布置的主、引双喷油器、高能点火装置及专用ECU的综合应用,是进一步发挥和提高低压缩比柴油转子发动机众多优点的一个有效的途径。With regard to the application of high pressure common rail injection system to a low compression ratios diesel rotary engine, special developments and experiments have been implemented. Firstly the high performance electronic control unite （ECU） that support all the tests was designed. Current developments focused on the applied fuel injection and ignition strategies, especially about the combustion configurations of injectors, ignition source, and combustion chamber. Currently the engine can run at 6 000 r/min steadily and the power of single rotor is about 30 kW at 4 000 r/min. Studies showed that the integrations of common rail injection system and the main and pilot duel injectors configuration assisted with glow plug ignition device and flexible ECU is a promising approach to improve the potential of low compression ratio diesel rotary engine.
