Commercial trucks employ range of power systems

Regulations continue to transform the powerplants used in commercial trucks, making fuel consumption and emissions reductions twin goals for many OEMs, upfitters and aftermarket suppliers at the NTEA Work Truck Show. Green trends and mileage requirements drove trends at the 20th annual show, which also addressed electrification and alternative fuels at the show's Green Trucks Summit.

“Some of the major challenges our industry will face in the coming decade are the result of emissions regulations,” said Shaun C. Skinner, president, Isuzu Commercial Truck of America. The Green Trucks Summit focused largely on electrification plans, but a couple major product announcements at the show were petroleum-based. Isuzu announced a pair of gasoline engines, while Mack unveiled its Class 6 and 7 medium-duty trucks, which use 6.7-L diesel engines.
