Agility Fuel Systems emphasized rail-mounted compressed natural gas fuel systems for over-the-road heavy-duty trucks.
Agility showed its Kenworth T800 test vehicle at the Southern California Gas stand at ACT Expo. The truck has been fitted with both CNG and LNG fuel tanks. “The purpose is to better understand how the components of each system work and improve those components to improve filling and fueling performance,” says Agility GM Scott Lucero. Agility continues to furnish roof-mounted and back-of-cab CNG tank assemblies too.
“Our new CNG systems are developed to the very specific needs of the class 7 and 8 trucks, making natural gas more usable in the largest segment of the truck industry,” Agility CEO Barry Engle said in a release for ACT Expo. The new products “combine the best of styling and functionality with a complete redesign to match today’s new aerodynamically styled tractors,” Agility says, with integrated fuel management module saving weight and space, “the industry’s fastest fill rate,” and new safety features.
Agility uses all-composite CNG cylinders from Quantum and Lincoln in the rail-mounted assemblies. “Tanks and steps are attached to the rail via specially engineered break-away brackets, which protect the cylinder from impact… wire embedded into the composite material alerts the driver if the covers are damaged.”
Traditional steel mounting straps are replaced with composite straps.
These, “with extruded rubber strap guides, prevent tank rotation that can stress fuel lines,” Agility says.
The Agility rigs feature an outer composite cover for impact protection too.
The new CNG systems are available with cylinders that can be strap- or neck-mounted in capacities ranging from 29 to 63 diesel gallon equivalent (DGEs) for longer operating ranges.
