Treatment of exhaust gas from automotive sources is required to meet government mandated limits on the emission of specified pollutants, primarily hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOX). Recent government initiatives are targeting the release of carbon dioxide (CO2), which is a greenhouse gas. The first three pollutants can be eliminated through the use of a catalytic after treatment system (catalytic converter), whilst the reduction of carbon dioxide can only be achieved by a reduction in fuel consumption, which in practice translates into a need for better fuel economy. The purpose of this research is to conduct a three year development program using a mixture of experimental and computational methods to yield a rigorous demonstration of the benefits of the Multi Chamber Catalytic Converter (MCCC) in Diesel engine (lean burn) exhaust gas after treatment systems. The demonstration project must be acceptable to OEM and vehicle manufacturers. The MCCC design is a concept pioneered by Vida Holdings. The project is a collaborative venture between the University of Alberta (Department of Chemical and Materials Engineering, and the Department of Mechanical Engineering) and Vida Holdings. Preliminary investigations have demonstrated the MCCC offers the potential to reduce emissions and improve fuel economy compared to a conventional converter, when tested for systems designed for stoichiometric gasoline fuelled engines. The exhaust system for the Diesel engine (lean burn) is substantially more complicated. It is intended to use the knowledge generated in the earlier study to develop the MCCC into a viable concept for this complex exhaust gas after treatment system. The main objectives of this project are to define the parameters that could lead to either reduced emissions, reduced need for precious metals, or enhance the vehicle fuel economy.

汽车尾气的处理必须满足政府规定的排放限值 特定污染物的排放，主要是碳氢化合物 (HC)、一氧化碳 (CO) 和氮氧化物 （氮氧化物）。最近的政府举措旨在释放二氧化碳 (CO2)，这是一种温室气体 气体。前三种污染物可以通过使用催化后处理系统（催化 转换器），而二氧化碳的减少只能通过减少燃料消耗来实现， 这实际上转化为对更好燃油经济性的需求。 本研究的目的是利用混合实验方法进行为期三年的开发计划 和计算方法，以严格证明多室催化的优点 柴油发动机（稀薄燃烧）废气后处理系统中的转换器 (MCCC)。示范工程 必须为 OEM 和车辆制造商所接受。 MCCC的设计是Vida首创的概念 控股。该项目是阿尔伯塔大学（化学系）之间的合作项目 和材料工程系、机械工程系）和维达控股公司。 初步调查表明 MCCC 具有减少排放和改善环境的潜力 在针对化学计量设计的系统进行测试时，与传统转换器相比的燃油经济性 以汽油为燃料的发动机。柴油发动机（稀薄燃烧）的排气系统明显更 复杂的。其目的是利用早期研究中产生的知识将 MCCC 发展成为一个 这种复杂的废气后处理系统的可行概念。 该项目的主要目标是确定可以减少排放的参数， 减少对贵金属的需求，或提高车辆的燃油经济性。
