摘要
以涡轮增压、涡轮复合、涡轮组合3种联合循环技术为对象,分析了各自理论循环特点并指出:涡轮增压联合循环技术实现了底循环与顶部循环的初级联合,底循环用来加强顶部循环但不对外输出功率;涡轮复合联合循环技术实现了底循环与顶部循环的有机结合,底循环除用来完善顶部循环外还参与对外输出功率并达到了较高的能量利用效率;涡轮组合循环技术实现了底循环与顶部循环的组合运行,底循环与顶部循环之间实现了模块化组合运行,使动力输出模式可按车辆的需求而变化。总结了各项技术的最新研究成果并对车用发动机联合循环技术的发展方向进行了展望。
The three combined cycle technologies including turbocharging, turbo-compounding and turbo-combining technolo- gies were proposed and the characteristics of every technology were analyzed. The turbo combined cycle technology realized the primary combination of the bottom cycle and top cycle and the bottom cycle was mainly used to strengthen the top cycle without the extra power output. The turbo-compounding cycle technology achieved the combination between the bottom cycle and the top cycle deeply and tightly, The bottom cycle was used to complete the top cycle with the extra power output and the energy utilization efficiency of the cycle also improved significantly. The turbo-combined cycle technology realized the modular com- bined working between the bottom cycle and the top cycle, which met the different power outputs of vehicle, requirements The latest research findings of the three technologies were summarized and the development trend of the vehicle engine combined cy- cle technologies was prospected.
