There is continued focus on controlling the emissions of pollutants from engines around the world. The Three Way Catalyst (TWC) has been successfully removing carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NOx) emissions from gasoline engines since the early 1970s. These catalysts operate under so-called stoichiometric conditions, in which there is a balance...

Copper zeolite SCR catalysts are being used to meet tighter NOx standards around the world. Global Emissions Management looks at work undertaken to improve their thermal stability by stabilising ammonia storage capacity. SAE paper 2009-01-0899, given at the 2009 SAE World Congress, describes the development of a new generation of SCR catalysts.

Past issues of Global Emissions Management have looked at selective catalytic reduction and diesel particulate filter technologies. In this issue, we look at combining them in order to reduce overall catalyst volume in after treatment systems. This article is based on paper 2009-01-0910, presented at the SAE World Congress in April 2009.
