• SCR does offer a potential route to achieve Tier 4 Final emissions standards in 2014 used as incremental technology to build on Tier 4 Interim technology. SCR and other options are part of Cummins technical evaluation work for Tier 4 Final. Cummins knows SCR technology better than any other engine manufacturer. In 2006, Cummins launched its on-highway engines certified to the Euro 4 standard using SCR in Europe. In addition to this, Cummins is utilizing SCR technology together with cooled EGR and the Cummins Particulate Filter to meet North America EPA 2010 emissions.
