摘要:
相继增压的动态切换特性对发动机性能有着重要的影响.为了研究相继增压系统空气阀相对燃气阀延迟关闭时间对切出过程柴油机性能的影响,建立了基于GT-power和MATLAB/Simulink的联合仿真平台.采用GT-power软件建立了TBD234V12柴油机仿真模型,MATLAB/Simulink软件建立了调速器、相继增压控制器和增压器喘振指数监测器仿真模型.对不同的阀门响应时间和空气阀延迟时间进行了相继增压柴油机切出过程瞬态仿真计算,结果表明切出过程中适当的空气阀延迟时间可以明显改善切出过程柴油机稳定性和排放,阀门响应时间增加会使柴油机性能和排放恶化.通过仿真计算确定了最佳的阀门控制策略.
Abstract:
The dynamic switching characteristics of the sequential turbocharging system strongly influence the engine performance. In order to research the influence of air valve’s time delay relative to exhaust valve on the diesel engine performance in the cutting out process, a co-simulation platform based on GT-power and MATLAB/Simulink was built in this paper. The GT-power software was used to set up the TBD234V12 diesel engine simulation model, and the MATLAB/Simulink software was used to build the governor model, sequential turbocharging (STC) system controller model, and the turbocharger’s surge index monitor model. The transient simulation of the STC system cutting out process with different response time and air valve’s time delay was proceeded. The simulation results indicated proper air valve’s delay time can obviously improve stability and reduce emission of the diesel engine, while the response time prolonging has the opposite effect. The best control strategy of valves was found out finally after the simulation calculation.
