Kenworth Truck Company is upgrading a number of products and producing some new ones.
The Clean Power no-idle system can be ordered as a factory-installed option on new W900s and T800s equipped with Kenworth's 72-inch AeroCab sleeper. The system uses dedicated, advanced deep-cycle batteries to power a thermal storage cooler with 21,000 BTUs of cooling capacity.
Fully compliant with the California Air Resources Board (CARB) idling regulations, the Clean Power system has the capability to provide engine-off cooling and heating, plus 120-volt power for hotel loads.
The AG130, AG210L, and AG400L suspensions are the latest additions to Kenworth's suspension family.
The AG130 is a robust proprietary front axle air-spring suspension that features a four-bag air spring configuration to “help reduce road inputs and vibration to provide the best riding suspension we've ever offered,” said Kenworth chief engineer Mike Dozier. “Roll stiffness is also improved to provide better handling and road feel.”
The disc-brake compatible AG130 will be available in 12,000- and 13,200-pound ratings for Kenworth's T660, T800, and T2000 Class 8 models.
The AG400L tandem rear suspension, also disc brake-compatible, is a 40,000-pound rated highway rear suspension system for the T660, T800, T2000, and W900 heavy duty models. A four-bag suspension with a proven trailing arm design, it supports fifthwheel height as low as 42 inches and has an 8½ inch ride height.
The AG210L, a two-bag version of the AG400L, is a 21,000-pound single-axle rear suspension for Kenworth's Class 6 and Class 7 T370 and T270 conventional models.
Kenworth will begin full production of new fuel-efficient medium duty, diesel-electric hybrid T270 Class 6 and T370 Class 7 conventional models this summer.
These hybrids, which qualify for federal tax credits, are expected to enhance fuel economy by up to 30 percent in pick-up and delivery applications.
Kenworth plans to begin production of its T800 liquefied natural gas (LNG) trucks in 2009. LNG-powered trucks reduce nitrogen oxide and greenhouse gas emissions in greater amounts compared to diesel-fueled trucks.
