Three-pronged attack with SCRT^®

Eminox announced some time ago that in conjunction with Johnson Matthey, it was heavily committed to the research and development of the Selective Catalytic Reduction Trap (SCRT^®) technology for the bus and truck markets.

The Continuously Regenerating Trap (CRT^®) System is Europe’s leading diesel particulate filter and effectively removes over 90% of most particulate matter. It also virtually eliminates hydrocarbons and carbon monoxides – the pollutants in the black smoke emitted by diesel engines.

By utilising SCR technology, the new SCRT^® also reduces NO_x emissions. In trials, the new system enables vehicles to meet the equivalent of both Euro 4 and 5 regulations.

Bringing together the expertise of Johnson Matthey in chemical technologies and Eminox in automotive system development and application engineering, has been critical. SCR technology requires this combination of expertise to develop a reliable and high performance system.

There are three SCRT^® system designs in an advanced stage of development undergoing field trials in the UK and Europe – Close-Coupled, Compact Drum, and Inline Configuration.

By combining the best elements from SCR and the market-leading CRT^® technology, the two companies are well on their way to marketing a system which can exceed even the most stringent emissions regulations; guaranteed to perform reliably in the real world.

The research and development team say that when SCRT^® comes to market later this year the system will reduce the emissions of harmful particulate matter by 90% and of Nitrogen Oxides by up to 85%.

“We are one of a few companies that has a range of several solutions that can address a wide range of vehicles,” said Market Development Manager Andy Frost. “We have worked in partnership with customers to develop a product which will not only meet the requirements of the legislation, but also provide the vehicle operator with a trouble-free technology.”
