Knight Transportation field tests Cummins X15N natural gas engine

Knight Transportation, the Phoenix, Arizona-based fleet, is reporting early results of its field test of Cummins’ new X15N natural gas engine, calling the early testing “successful.”

The fleet has been running a truck with this engine in Southern California. The truck is fueled exclusively with Clean Energy ultra-low carbon Renewable Natural Gas (RNG) anchored by Clean Energy’s station in Carson, California.

“The feedback in the development process is invaluable to the products long-term success for our customers. The suite of integrated Cummins technologies used on these trucks from engine, aftertreatment, and fuel storage to transmission, axles and the digital features that pull them all together in their most optimized form demonstrates the value of our next generation of product to our customers,” said José Samperio, vice president of North American on-highway business at Cummins Inc.

The field testing with Knight-Swift will continue through full production of the X15N powertrain in 2024.

Fontaine Specialized announced the new Magnitude 75 lowbed trailer. This 3+3+2 modular multi-purpose trailer is designed to transport a diverse range of loads, according to Fontaine, who adds that the Magnitude 75 comes in three distinct deck options: flat (MFLD), drop side rail (MDSR), and beam (MBMD)."The Magnitude 75 epitomizes versatility in heavy-haul lowbeds. It accommodates loads of up to 75 tons in 16 feet as a 3+2 or with five close coupled axles," said Heather Gilmer, vice president of sales. "Furthermore, it adeptly handles 70 tons in just 12 feet configured with the tandem axle EQ2 spreader. This adaptable trailer features a hydraulic detachable gooseneck and a tridem axle bogie, each providing seven ride height positions. This enhanced flexibility is invaluable for operators maneuvering heavy loads across obstacles or beneath bridges.”Fontaine says the Magnitude 75 was made with 100,000-lb. minimum yield steel main beam flanges; and the flat and beam decks boast a 24-in. loaded deck height, while the drop side rail deck reduces it to 15-in. At full load, all modular decks offer 6-in. of ground clearance.
