Aftertreatment System Technologies

The automotive aftertreatment system reduces emissions of carbon monoxide, oxides of nitrogen (NOX) and other smog-forming pollutants found in automotive exhaust. Southwest Research Institute is a pioneer in research and testing of aftertreatment system technologies that help the automotive industry meet and exceed emissions and fuel efficiency standards.

Emissions Analysis from Combustion to Tailpipe

Emissions of carbon monoxide (CO), oxides of nitrogen (NOX), unburnt hydrocarbons and particulate matter are controlled in either the automotive combustion system or the aftertreatment system. SwRI develops analytical solutions for individual catalyst components, full-size exhaust aftertreatment systems, and related emissions control technologies.

Catalyst Aftertreatment Solutions

Our catalyst aftertreatment solutions include analysis of diesel oxidation catalyst (DOC), diesel exhaust fluid (DEF), diesel particulate filter (DPF), selective catalytic reduction (SCR) systems and ammonia slip catalysts (ASC).

Exhaust Aftertreatment Technology

Our exhaust aftertreatment solutions for diesel and other fuel types include full-size aftertreatment system accelerated aging on our burner system (ECTO-Lab), particle and soot accumulation on filters, diesel exhaust fluid (DEF) development and testing, and other emissions control technologies.
