Navistar will use the engines in its International TranStar and WorkStar trucks.
VANCOUVER—Cummins Westport Inc. will provide its natural gas engines for Navistar trucks, but the joint venture of U.S-based Cummins Inc. and Vancouver-based Westport Innovations Inc offered few details about the contract.
The company’s natural gas engine was first used in the transit and waste transport markets.
Navistar will install the Cummins Westport ISL G in its International TranStar and WorkStar trucks.
The 320hp ISL G is an 8.9 litre stoichiometric cooled-exhaust gas recirculation (EGR) engine that operates on either compressed natural gas or liquefied natural gas.
In 2010, Navistar closed its truck manufacturing plant in Chatham, Ont., for good, a move that put 1,100 workers out of work.
Navistar International Corp. is a holding company whose subsidiaries manufacture commercial and military trucks, diesel engines, school and commercial buses and recreational vehicles.
