Kenworth Truck Company is showcasing four natural gas trucks in its booth during the Alternative Clean Transportation (ACT) Expo June 24-27 at the Walter E Washington Convention Center in Washington DC.
Kenworth’s natural gas truck lineup at the ACT Expo 2013 features three Kenworth T800s and a T440. Leading the list is a short hood (116.5-inch BBC) Kenworth T800 roll on/roll off with the new Cummins Westport ISX12 G heavy duty natural gas engine and compressed natural gas (CNG) fuel system featuring back of cab tanks from Trilogy Engineered Solutions. A T800 day cab tractor also has the Cummins Westport ISX12, which offers a range of ratings to 400 horsepower and 1,450 ft-lbs of torque, optional engine brake, and manual and automatic transmission capability to meet customer needs. The ISX12 G also is available with the aerodynamic Kenworth T660 and Kenworth W900S.
In addition, Kenworth will exhibit a T800 LNG tractor with a 15-liter Westport heavy-duty natural gas engine with 450 hp and 1,650 lb-ft of torque. The T800 LNG truck is a good choice for Class 8 applications, including regional haul, linehaul, port and drayage with loads requiring more power and torque and an operating range of more than 400 miles. It can be ordered in a gross combination weight of up to 80,000 pounds for over-the-road operation with additional ratings exceeding 100,000 pounds available for certain applications. The T800 LNG truck is available with a daycab, extended daycab, or 38-inch AeroCab sleeper.
Also on display is a T440 CNG truck spec’d with the 8.9-liter Cummins Westport ISL G engine, Agility rail-mounted fuel system, and Allison 3000HS six-speed automatic transmission. Rated at 320 hp and 1,000 lb-ft of torque, the ISL G engine's torque curve closely matches that of its diesel counterparts. It is available as a straight truck or tractor in a gross vehicle weight ranging from a heavy Class 7 vehicle at 33,000 pounds up to a light Class 8 truck at 68,000 pounds.
