Burr Ridge, IL-based Dillon Transport will add 25 Kenworth T800s with liquefied natural gas engines to its 450-plus vehicle fleet.
The tractors are short hood day cabs and will be powered by the new Cummins Westpory ISX12 G heavy-duty LNG engine.
“We’re excited to expand our leadership in natural gas trucks by becoming among the first Kenworth customers to select the Cummins Westport ISX12 G engine. The Kenworth T800 is a high quality, rugged and reliable truck that fits well into our green initiatives,” said Jeff Dillon, president and owner of Dillon Transport.
Dillon is a liquid and dry bulk carrier operating primarily east of the Rockies. The fleets will run the tractors out of its Dallas, TX, terminal, hauling asphalt, sand and other raw bulk products.
The trucks are specified with both a 72- and a 150-gal. LNG tank to provide a range of approximately 650 mi. The trucks are expected to make two 600-mi. round trips per day in a driver slip-seat operation. LNG refueling will typically be done twice a day at the Clean Energy station located at Dillon Transport’s Dallas terminal.
“The new ISX12 G offers an excellent natural gas option for those regional, refuse and pickup and delivery applications that need a little more power and torque than the 8.9-liter Cummins Westport ISL G,” said Andy Douglas, Kenworth national sales manager for specialty markets.
The Cummins Westport ISX12 G engine requires a single fuel source and can run on either LNG or CNG (compressed natural gas. The natural gas engine uses a maintenance-free, three-way catalyst and does not require a diesel exhaust fluid (DEF) tank, diesel particulate filter (DPF) or selective catalytic reduction (SCR) technology.
Kenworth offers the ISX12 G in ratings to 400 hp. and 1,450 lbs.-ft of torque.
