The company introduced the engine this week in an LNG tractor for port and regional haul applications.
The Cummins Westport engine is an 8.9-liter stoichiometric cooled-exhaust gas recirculation engine, which meets 2010 EPA emissions standards with no aftertreatment required. It has ratings from 250 to 320 horsepower.
"By launching the Cummins Westport ISL G in the M2 112 tractor, Freightliner will be able to provide customers with clean, economic natural gas power for a wide range of applications," Roe East, president of Cummins Westport. "By the end of 2010, Freightliner Trucks expects to have a complete CWI-powered lineup with configuration options for over 90 percent of truck applications in North America."
Daimler plans on rolling out a CNG version of the tractor in late 2009, followed by a CNG single axle tractor and vocational configurations.
