The ISL G engine is 2010-compliant without the use of selective catalytic reduction (SCR) or a diesel particulate filter (DPF)
Kenworth Truck Company has expanded its green product line with the introduction of the Kenworth T440 natural gas model powered by the Cummins Westport ISL G engine. Now available for order, the new Kenworth T440 natural gas truck is focused on local and regional haul and vocational applications. The versatile T440 becomes the latest Kenworth truck able to operate on both compressed natural gas (CNG) and liquefied natural gas (LNG), joining Kenworth’s W900S which began offering those options late last year. Both models are equipped with the ISL G engine and Allison transmissions.
“There is growing demand in CNG and LNG vehicles across the United States and Canada. The natural gas powered Kenworth T440 offers outstanding horsepower, torque and performance and provides an excellent, low-emission and cost effective transportation solution for local and regional haul fleets,” said Gary Moore, Kenworth assistant general manager for marketing and sales.
“The tight turning radius and lightweight chassis also make the T440 natural gas vehicle an excellent choice in a mixer or dump application.”
The T440 has a gross vehicle weight (GVW) ranging from a heavy Class 7 vehicle at 33,000 lbs. up to a light Class 8 truck at 68,000 lbs. and is available with 12,000- to 22,000-lb. rated front axles, 21,000- to 26,000-lb. rated single rear axles, and 40,000- to 46,000-lb. rated tandem rear axles.
The ISL G engine operates on either CNG or LNG, both of which are cost-effective, low-carbon, and low-emissions fuels. Rated at 320 hp and 1,000 lb-ft of torque, the ISL G is 2010-compliant without the use of selective catalytic reduction (SCR) or a diesel particulate filter (DPF). CNG and LNG fuel tanks can be configured to suit customer applications and range requirements. Kenworth also offers the T800 LNG truck equipped with the Westport GX engine.
In 2009, Kenworth became the first truck manufacturer to receive the U.S. Environmental Protection Agency’s Clean Air Excellence award in recognition of its environmentally friendly products.
