Westport Innovations Inc. (WPT:TSE) has announced that is has begun a co-operative technology development project with MAN Nutzfahrzeuge AG of Munich, Germany, one of the largest manufacturers of medium and heavy trucks in Western Europe. Under a one-year agreement between the two companies, Westport will design and test a high-performance natural gas fuel system for a MAN 12-litre diesel truck and bus engine. Westport expects that the MAN engine using Westport technology would comply with European emission standards and would allow commercial fleet operators to realize significant savings on fuel costs because natural gas is less expensive than diesel fuel.
