Description:

The Johnson Matthey SCCRT, v.1 technology is a urea-based SCR system combined with a CCRT filter designed for on-highway light, medium, and heavy heavy-duty diesel, urban and non-urban, bus exhaust gas recirculation (EGR)-or non-EGR-equipped engines for use with commercial ultra-low-sulfur diesel fuel. This environmental technology verification (ETV) report reviews the performance of this technology. ETV testing of this technology was conducted during a series of tests in March 2010 and February 2011 by Southwest Research Institute (SwRI), under contract with the Air Pollution Control Technology Center. The performance verified was the percentage of emissions reduction achieved by the technology for nitrogen oxides (NOx), particulate matter (PM), hydrocarbons (HC) and carbon monoxide (CO) relative to the performance of the same baseline engine without the technology in place. Reductions were 72-77%, 89-98%, 80-100% and 66-100%, respectively. Operating conditions were documented, and ancillary performance measurements were also made. The APCT Center quality manager has reviewed the test results and quality control data and has concluded that the data quality objectives given in the generic verification protocol and test-QA plan have been attained.
