国六GPF应用方案及控制策略研究

Control Strategies of Gasoline Particulate Filters for China 6 Emission Standard

结合实际整车应用项目对GPF(汽油机颗粒捕集器)应用方案及控制策略进行了论述,介绍了GPF在实际项目应用中的整体布置方案及各零部件的选型原则;从碳载量模型预估、再生模式判断、仪表提示灯控制策略及售后市场解决方案等方面论述了一种GPF控制策略,该控制策略能够比较全面有效地解决国六项目GPF面临的实际应用问题。

Combined with the actual vehicle application project, the application plan and control strategy of GPF(Gas Particular Filter) are discussed, and the overall layout plan of GPF in actual project application and the selection principles of various parts are introduced. A GPF control strategy is discussed in terms of carbon load model estimation, regeneration mode judgment, instrument prompt lamp control strategy, and aftermarket solutions. This control strategy can comprehensively and effectively solve the practical application problems faced by the GPF project for China 6 emission standard.
