Design, optimization, and control on a novel diesel engine aftertreatment system with multi-chamber catalytic converter (MCCC)

本课题的研究目的是将MCCC技术从汽油机催化转化器顺利转移到柴油机后处理系统。多室催化转化器（MCCC），这是建议，专利，并完全拥有维达控股公司有限公司，是对当前催化转化器设计的修改。 对维达控股公司的汽油发动机的研究表明，它在去除NOx、降低制造成本和提高燃油经济性方面具有明显的优势。虽然MCCC技术在汽油机上显示出了上述优点，但在柴油机后处理系统中的应用还需要进行全面的研究，柴油机后处理系统比汽油机复杂得多。 在柴油发动机中，MCCC技术将被纳入柴油氧化催化剂（DOC）中。 这一修改将改变下游的化学成分、压力和温度条件。 因此，DOC下游的其他后处理部件，包括柴油颗粒过滤器（DPF）和选择性催化还原（SCR）反应器，需要重新设计、优化和适当控制。为了实现新型柴油机后处理系统与MCCC的最佳操作，研究将通过柴油机MCCC设计，后处理系统优化，建模和控制进行。 本项目的预期成果是基于MCCC的柴油机后处理系统的设计、优化和控制的新技术和系统化技术，有利于降低排放、降低生产成本和燃油经济性（通过降低背压）。这将大大扩展MCCC的应用范围，并巩固维达控股有限公司在汽车排放控制创新方面的地位。 这项研究也将大大有利于加拿大和全球汽车行业在减排，燃料可持续性和生产。

This research aims at smoothly transferring the MCCC technology from gasoline engine catalytic converter to diesel engine aftertreatment system. Multi-Chamber Catalytic Converter (MCCC), which is proposed, patented, and fully owned by Vida Holdings Corp. Ltd., is a modification to the current catalytic converter design. Studies for gasoline engines from Vida Holdings have shown its tangible advantages in the removal of NOx, manufacture cost reduction, and fuel economy improvement. While MCCC technology demonstrated above advantages in gasoline engines, its application in diesel engine aftertreatment system, which is much more complex than that of the gasoline one, still needs to be comprehensively studied. In diesel engines, the MCCC technology will be incorporated in the Diesel Oxidation Catalysts (DOC). This modification will change the downstream chemical contents, pressure, and temperature conditions. Therefore, other aftertreatment components downstream DOC, including Diesel particulate filter (DPF) and selective catalytic reduction (SCR) reactor, need to be redesigned, optimized, and properly controlled. To achieve the optimal operations for the novel diesel aftertreatment system with MCCC, the research will be performed through MCCC design for diesel engines, aftertreatment system optimizations, modelling, and control. The expected outcomes of this project are the novel and systematic technologies on design, optimization, and control for MCCC-based diesel engine aftertreatment system, benefiting the emission reduction, production cost reduction, and fuel economy (through back-pressure reduction). This will significantly extend the application of MCCC and strength the position of Vida Holdings Corp. Ltd. in automotive emission control innovations. This research will also greatly benefit the automotive sector in Canada and worldwide in emission reduction, fuel sustainability, and productions.
