Continuing advanced emissions research

The Advanced Combustion Catalyst and Aftertreatment Technologies (AC2AT) consortium, led by Southwest Research Institute (SwRI), will continue to focus on advanced emissions research by concentrating on four specific research projects in its second year.

The joint-industry programme provides a precompetitive, collaborative approach to evaluating engine emissions and developing tools to improve advanced engine technologies through the application of catalysts.

“In the first year, we’ve made progress in our understanding of the complex nature of emissions from today’s high-performance, high-efficiency gasoline and diesel engines,” said Dr Cary Henry, a Manager in SwRI’s Engine, Emissions, and Vehicle Research Division, who leads the AC2AT consortium. “This year we will focus on specific projects to improve aftertreatment and fuel efficiency strategies for these engines.”

The consortium’s second-year goals include modelling emission control systems that use urea and selective catalytic reduction, as well as characterising the chemistry of emissions from advanced combustion systems. SwRI engineers will evaluate techniques for treating low-temperature exhaust gas emissions and model how ash emissions associated with oil ingestion affect aftertreatment components.

The four-year AC2AT consortium was formed in 2014 with members representing engine manufacturers and affiliated businesses in the automotive industry. Consortium members receive a royalty-free license for patents earned by SwRI engineers during the programme.
