Kenworth is adding cab temperature monitoring for the T680 and T880 models with its Auto Start and Stop Capability and an optional Espar Airtronic D4 fuel-fired bunk heater. The Espar bunk heater produces nearly double the BTUs of Espar’s previous generation heater. “For operators running in cold temperatures, or shut down for a 34-hour reset, our new offerings give a one-two punch in vehicle performance and driver comfort,” said Kevin Baney, Kenworth chief engineer. “We’ve built our power management system into what we feel is the most comprehensive system in the market. And, for engine-off, constant heat in the sleeper, the new Espar Airtronic D4 heater has a btu rating up to 13,650, and is available for the Kenworth T680 and T880 specified with either the 76″ or 52” sleeper. The engine Auto Start And Stop system monitors the starting batteries and the batteries used to power hotel loads. When the batteries need to be recharged, the system starts the engine to begin battery charging. The system also monitors oil temperature, starting the engine when the temperature falls below a pre-determined level.
Kenworth will offer the Bendix Wingman Advanced collision mitigation system as an option on its medium-duty Kenworth T270 and T370 trucks. Wingman Advanced is a radar-based system that delivers adaptive cruise control with braking, along with autonomous emergency braking technology to help drivers avoid rear-end collisions. Using a radar sensor mounted to the front of the vehicle, Bendix Wingman Advanced delivers warning alerts to drivers. The system provides following distance, impact and stationary object alerts, which are always available-whether or not cruise control is engaged. When drivers engage cruise control and set speed, the system will actively intervene to help them maintain a safe following distance behind a forward vehicle by reducing throttle; engaging the engine retarder; or, if necessary, applying the brakes. “Bendix Wingman Advanced is a proven system that can deliver performance on the road, data for improved fleet management and a quick return on investment for the fleet,” said Jason Skoog assistant general manager for sales and marketing. “The system can help avoid collisions on the freeway but also in urban driving conditions experienced by medium duty truck operators.”
Prestolite Electric’s Leece-Neville Heavy Duty Systems brand is offering a new in-line gear reduction starter motor called the M-110608 for Paccar’s MX-11 and MX-13 engines. The starter motor also works with Kenworth 2010 and newer engines up to 16 liters in size. The starter is designed for improved performance and reliability as a bolt-in replacement for engines served by Paccar, Mitsubishi, and Delco Remy 39MT units. The in-line gear reduction design provides greater power from a lighter unit and is made to fit in tighter spaces. The new Leece-Neville 12 volt M110608 starter motor features Prestolite’s Integral Magnetic Switch/Soft Start Relay technology, which helps to eliminate voltage drop issues by minimizing wiring between the relay and solenoid. Other key enhancements include a next-generation communicator with an oversize copper cross-section, enlarged armature to minimize air gap losses, heavy-duty brush plate for improved conductivity, and an e-coating on the housing for resistance to corrosion.
In a step toward more integrated drivetrains in Kenworth and Peterbilt trucks, Paccar announced a new 40,000-pound tandem axle that saves weight and improves fuel economy. This axle is “really helping us make steps toward an integrated powertrain” Landon Sproull, Paccar vice-president, told reporters at the American Trucking Associations Management Conference and Exhibition. The new axle is designed for linehaul, regional haul, and pick-up and delivery customers, reated at 40,000 pounds and supporting a gross combination weight of 80,000 pounds. It offers ratios from 2.47 to 3.70 with engine torque compatibility up to 1,650 lb-ft and multi-torque ratings compatibility up to 1,750 lb-ft. The Paccar axle features a pinion-through-shaft design that simplifies power flow in the axle for maximum efficiency. A laser-welded carrier design eliminates internal fasteners, and reduces oil churn and weight. Overall the axle offers up to 150 pounds of weight savings, according to Paccar. Kenworth will begin offering the axle to customers in January 2017.
Along with Ford’s super duty pickup lineup, the 2017 super duty chassis cabs, including F-450 and F-550 models, get a reboot with the new product launch. The chassis cabs arrive with a 7,500-lb gross front axle weight rating – up 500 lbs from previous models – designed to support bigger snow plows , utility buckets, and other vocational upfit equipment. The F-450 and F-550 chassis cabs have a combined weight rating of up to 40,000- lbs, which Ford notes is half the 80,000-lbs for heavy trucks. The manufacturer also highlights the 2017 chassis cabs frame, which Ford says is 95% high strength steel and has eight times more torsional rigidity than prior models. For the first time with the super duty trucks, the bodies boast high-strength aluminum throughout the cab, which Ford says allows for “significant increase in towing and payload capabilities”. The new models offer weight savings of up to 350 lbs. with the materials used. An optional Ford 6.7L Power Stroke V8 diesel brings the super duty chassis up 30 hp and 90 lbs-ft of torque to 330hp/750lbs-ft, the most ever for the lineup. Based on the 330-hp configuration, Ford says the F-650 and F-750 models provide a B10 engine life of 500,000 miles, meaning 90% of them are expected to reach that point without requiring major engine service. According to the OEM the 6.7L is 25% quieter at 60 mph and up to 45% quieter at idle inside the cab.
Kenworth is adding a set-forward front axle configuration to its T880, the company announced at the ConcreteWorks truck show hosted by the National Ready Mix Concrete Association. The new configuration-the T880S- is designed for fleet and truck operators in ready-mix, dump, and mobile crane applications. Jason Skoog, Kenworth assistant general manager for sales and marketing, says the truck is available with a 114-inch BBC and best-in-class 28-inch bumper setting. Tare weight is minimized, he adds, and weight distribution is optimized so the Federal Bridge Formula can be easily met. The bumper setting is especially important in spec’ing Bridge Formula chassis required to stay under the 40-foot length limit. The new T880S is available with a set-forward front axle ranging from 14,600 pounds to 22,800 pounds. Single, tandem or tridem drive axles and a wide variety of factory installed lift axles, are among a range of options available to meet the most demanding jobsite requirements. The T880S is standard with the 12.9 liter Paccar MX-13 engine, which provides up to 500-hp and 1850 lb-ft of torque.
Glider kits will be almost outlawed by 2021 due to provisions of the federal Phase 2 Greenhouse Gas and Fuel Economy rules released earlier this month. Starting in January of 2021 gliders will be only allowed for their original purpose, which was reclaiming late-model powertrains from wrecked trucks. This goes back many years, to when glider kits were bought as service parts. Today, truck builders produce glider kits for assembly by individuals and commercial concerns. Though they make up a small percentage of total new truck sales, gliders produce far more exhaust emissions. The EPA became concerned after a surge in sales from a few hundred per years 20 years ago to more than 20,000 in 2015. Most of those were high-mile highways trucks with older engines that spew many times more exhaust emissions than new engines. “Although glider vehicles make up only 5% of heavy-duty tractors on the road, their emissions would represent about one-third of all NOx and PM emissions” the EPA said. Instead of abruptly outlawing them, however, the new rules will phase out gliders over the next four years.
