System removes exhaust soot

Oct 3, 2012 by Triton Staff

Seattle-based Northern Lights, a marine power generation and propulsion company, has created a solution for removing soot and particulate matter often associated with diesel powered equipment.

With DECS, a Diesel Exhaust Cleaning System, exhaust gas is routed through a catalytically coated ceramic filter. Soot is trapped and the filter is kept free of restrictions. DECS uses a passive regeneration process. With DECS, the Northern Lights generator set functions as normal while particulate matter is continually burned off using the heat emitted by the engine’s exhaust. At an exhaust gas temperature of 300° C, soot burns away and transforms into carbon dioxide.  

DECS is CARB Level 3 verified and NO2 compliant, and is custom engineered. A monitoring system records engine information while meeting or exceeding classification society requirements. DECS is based on DCL International technology.

“DCL International’s emissions control technology has been proven to be effective on a global scale,” said Colin Puckett, Northern Lights’ director of marketing. “Together, DECS will provide an ideal solution for the new generation of yachts that will be managing exhaust systems using safer, more practical and reliable technology.”
