In order to improve performance of the DA465Q gasoline engine, a substantial amount of research was done to optimize its turbocharging system. The research led to the GT12 turbocharger being selected and its turbocharging parameters being settled. Based on these tests, rational matching was worked out for respective components of the turbocharging system. Results show that this turbocharger allows the engine to easily meet the proposed requirements for power and economic performance, giving insight into further performance improvements for gasoline engines. 相似文献

为了降低柴油机测控系统的开发时间和费用,采用dSPACE硬件在环仿真平台,对柴油机测控系统进行了开发.采用BP神经网络改进了柴油机准稳态模型,使用Matlab/Simulink软件建立了TBD620V12型增压柴油机的改进准稳态模型,并检验了新增的爆发压力模型和滑油压力模型的精度.在dSPACE处理器中运行该仿真模型,并通过输入输出接口板及接口电路将测控系统与dSPACE平台连接,实现了测控系统与柴油机模型的闭环仿真.仿真结果与试验数据对比表明:相对误差小于3%,从而可用硬件在环仿真代替实机试验,缩短了测控系统的开发周期,并降低了开发成本. 相似文献
