Columbus, IN-based engine maker Cummins said its off-highway engines have been certified by the EPA’s Vehicle Certification Agency (VCA) as compliant to the Stage IIIA standards for oxides of nitrogen (NOx) and particulate matter (PM) set to go into effect in January 2006.

Dave Crompton, Cummins vp for mid-range engines, said the company’s Stage IIIA architecture provides the base platform for meeting Stage IV regulations in 2014 with the addition of aftertreatment systems. “This gives our customers the maximum possible platform stability in the face of new requirements,” Crompton said.

The certified Cummins QSM Stage IIIA will go into production in July with its advanced in-cylinder combustion “recipe” and an identical footprint from its EPA Tier 2 predecessor. The 11-liter, six cylinder engine is rated from 290 to 400 hp and utilizes the company’s Celect fuel system with advanced electronic controls.
