Rush Unit Also Has a New Regulator to Enhance Trucks’ Range
Momentum Fuel Technologies has introduced a 150-diesel gallon equivalent back-of-cab assembly for CNG fuel cylinders, adding the system to its line-up for Class 6 to Class 8 trucks.
The new CNG cylinder array includes a new range-boosting pressure regulator: it allows the system to operate from 3,600 pounds per square inch when full down to a minimum of 230 psi – an improvement from the previous 450-psi minimum. Thus the new 150-DGE assembly, “geared for over-the-road haulers, has the range equivalent to a 160-DGE fuel system due to its lower operating pressure,” states a release.
“The new pressure regulator is designed to allow drivers to go further on a tank of fuel,” Momentum GM Mike Zimmerman says in the 150-DGE product announcement. The new regulator is designed to reduce leak points and weight, and the high-capacity filter, Momentum says, “is larger than most competitive products and designed to be serviced less frequently.”
The new 150-DGE BoC system mounts between factory cab extenders, the company says, with neck-mounted cylinders for enhanced durability. It features “a tested and proven enhanced pressure relief device system with eight fast-flow PRDs to allow rapid evacuation of CNG in case of emergency.
“New and replacement parts for this system are manufactured in-house by Momentum Fuel Technologies, ensuring quality and improving speed to customers.”
The New Regulator Is Standard
Momentum’s new pressure regulator comes standard on all of the company CNG assemblies, including the firm’s 115- and 75-DGE BoC units and 30-, 40- and 45-DGE) side-mount assemblies, which entered production this past autumn. The side-mount units now have “a re-designed plumbing arrangement” too.
Another further enhancement is the painting of all high-pressure fuel lines yellow, for easier identification by technicians. “Painting the high-pressure fuel lines in yellow helps drivers and technicians stay safe, which is our top priority,” Zimmerman said.
‘A Viable option,’ Says Rusty Rush
“We believe that natural gas remains a viable option for some customers, and we are pleased to invest in product technology to meet a wider range of needs in the marketplace,” Rush Enterprises chairman, CEO and president Rusty Rush said in the 150-DGE announcement.
“We continue to expand our Momentum compressed natural gas fuel system product line in support of fleets who prefer to operate CNG-powered vehicles,” he said.
Rush/Momentum announced the new assembly at the American Trucking Associations’ TMC/Technology and Maintenance Council annual meeting, which wrapped up late last week in Nashville.
Rush Enterprises launched its Momentum Fuel Technologies unit at ACT Expo 2015 in Dallas (F&F, May 4, 2015).
