Westport Innovations has agreed with Isuzu Motors to develop a prototype Elf truck powered by a Westport Cycle natural gas engine. The project has been initiated by Isuzu, which will also fully fund it. Leading the effort is Isuzu's Powertrain Engineering Division and Natural Gas Group. The development will take place at Isuzu's engine manufacturing plant in Fujisawa, Japan. Westport will support Isuzu's vehicle team in producing, testing and calibrating the prototype vehicle and will retain all ownership of its Westport Cycle intellectual property, which uses high-pressure direct injection to bring natural gas into the engine cylinder.
