ATLANTA – As the first OEM to announce it will meet EPA 2010 emissions standards on its medium-duty engines without selective catalytic reduction (SCR), International officials said they’re poised to continue their leadership in the Class 6 and 7 segments, according to the Web site

Steve Guillaume, general manager, medium truck group with International, said the company’s ability to meet the stringent 2010 emissions standards without NOx aftertreatment “is something we’re very proud of.”International claims it can meet EPA2010 emissions standards on its medium-duty MaxxForce engines by tinkering the fuel system, air management, combustion processes, and controls.

In field testing, the MaxxForce 7 demonstrated a 13-percent fuel mileage improvement over its predecessor, the VT 365. The MaxxForce DT, meanwhile, showed a nine percent improvement over the International DT 466.

Guillaume said International plans to continue developing medium-duty hybrid solutions, which promise to offer even greater fuel savings.

The company’s goal is to sell 1,000 DuraStar hybrids this year.
