Cummins has released the Guidanz mobile app, allowing users to read prioritized engine fault codes and other key engine information from a vehicle.   The Guidanz app offers critical information about Cummins 2007 and later on-highway engines and Tier 3 and later off-highway engines.  The information can be emailed to an operations manager, service providers or a Cummins Care representative directly from the app to initiate the service process.  The Immediate Assessment feature of the Guidanz app is available to certified service providers to help improve shop scheduling.  As providers begin to adopt Immediate Assessment in the coming months, they will not only be able to read the fault code, but assess the severity of the fault, how quickly it can be repaired, what repair parts are likely needed, and start a work order before a customer enters the service bay.  To operate, the Guidanz app must be paired with an Inline mini Bluetooth adapter or Inline 7 and requires and IOS or Android device.  Though the Guidanz mobile app requires a smart phone or tablet to operate, it will still function when the device is offline.  Customers are provided a list of fault codes regardless of connectivity, so even when operating in remote locations customers are still able to access enough information to call operations managers or service providers.

The first new product has emerged in the wake of Wabco’s purchase of Laydon Composites, and it comes in the form of a self-deploying trailer boat tail.  Introduced at the Technology and Maintenance Council annual meeting, the OptiFlow AutoTail automatically deploys at 45 mph and closes at 10mph, drawing on speed data from the trailer’s antilock braking system.  The automated opening helps to ensure that the potential aerodynamic benefits are always realized at highway speeds, while the closing will help to ensure the equipment is not damaged when a trailer is backed into a loading dock.  OptiFlow Auto Tail earned an EPA SmartWay designation through tests by Canada’s National Research Council.  Tests show the panels can improve fuel economy by up to 4.3% at highway speeds, reducing carbon dioxide emissions by 4.8 tons per trailer per year.  The device differs from a competing system in several ways.  Rather than using hinges, the panes use cantilevers to swing into place.  They’re also shaped for better aerodynamic flow, only 21 inches wide, and made of injection-molded thermoplastic.  It was a rapid development process.  Wabco purchased Laydon Composites in April 2016 and the Ontario company’s former president Brian Layfield said his team had barely discussed the technology at the time of sale.  But now the company has the backing of a global company behind it.  “Its been for me really rewarding going from three engineers.  I now have the ability to tap into 2,400 engineers,” Layfield said, referring to available support and cost synergies.  Wabco, meanwhile, is looking to maintain the group’s entrepreneurial spirit.  “In the end it’s all about getting out of the way,” said Jon Morrison, Wabco president.  “We recognize what we know and what we don’t know.”  Wabco is also offering its manually deployed OptiFlow Tail for the first time in North America.  The OptiFlow Tail offers the same fuel savings as OptiFlow Auto Tail and is easily upgraded to the autodeploy version, according to the company.

Cummins announced that its B4.5, B6.7 and L9 engine platforms are compatible with certain kinds of renewable diesel fuels.  Both on-highway and off-highway versions of the engines and all vintage engines are approved to use renewable diesel fuels meeting the EN 15940 specification.  Compared to conventional diesel fuels, paraffinic diesel fuels can potentially reduce greenhouse gas emissions by 40% to 90% over the total life of the vehicles, according to Cummins.  Cummins held an 18-month field test of its engines running 100% paraffinic diesel fuels in order to study the effects of the fuel on engine performance, aftertreatment and fuel system durability.  Engine performance remained stable and consistent while using the paraffinic fuel, Cummins found.  Depending on the application and engine duty cycle, fuel economy could take a hit of up to 6%, mostly due to the lower density of paraffinic fuels compared to regular diesel.  Cummins approval for the use of renewable diesel with B6.7 and L9 engines aligns with the introduction of EN 15940, a final European CEN specification for paraffinic diesel fuels.  Paraffinic fuels include hydrotreated vegetable oil, gas-to-liquids, and biomass-to-liquids.  Operators of Cummins-powered trucks and bused are required to source all paraffinic fuels from high-purity suppliers meeting EN 15940, as this ensures that the fuel contains the necessary lubricity additive for use in a diesel engine.  “Focused on energy diversity and enabling the power of choice, Cummins has provided another approved fuel option to help the continued reduction of emissions,” said Jim Fier, Cummins vice president of engineering.  “The use of paraffinic diesel allows customers to minimize their emissions-based footprint, without additional capital investment.  Plus, they have the comfort of knowing that Cummins conducted a thorough analysis prior to approval.”

THE T680

Posted: June 1, 2017 in Kenworth

The T680 has been on the road for approximately 5 years.  Following are a few thoughts from our dealership on this wonderful truck.  We at Wallwork believe this is the highest quality model Kenworth has ever released.  The cab is constructed from a variety of materials with each selected for long life and to eliminate cab noises such as wind noise and squeaks and rattles.  The robotic constructions process means assembly is done the same time after time.  Our 3 piece hood makes for easier, less costly, repairs, if they are needed.  Drivers like the wide cab, 83″ as opposed to 75″ on the T660.  The wide cab allows for 23″ of space between the seats making for easy entry into the sleeper.  A feature liked by lots of our customers is the dash.  Switches are within easy reach and are grouped so the driver has an easy time locating the one he is looking for.  The windshield is the largest of any Kenworth model making for great visibility.  The large windows in the doors add to this feature, allowing the driver to easily see the traffic around him.  Another visibility feature is the low height at the front of the hood.  A T680 hood is 4″ lower than the T660 hood,  allowing the driver to see objects close to the front of his truck.  Another improvement is the increased storage space in the sleeper.  The T680 with a 76″ sleeper has approximately 40% more storage than a T660 with a 72″ sleeper.  The swivel table in the sleeper that doubles as a work area and a dinner table is also popular.  Add a factory installed refrigerator/freezer and you almost feel at home.  If you aren’t familiar with this wonderful truck stop and see one.

Transfer Flow has released an aftermarket replacement fuel tank for the F-450 Super Duty short bed, crew cab diesel truck.  The hot-dipped aluminum alloy steel tank nearly doubles the original useable fuel capacity, storing a total of 60 gallons.  The tank was designed and built with 12-gauge aluminized steel for better strength and corrosion resistance.  It was designed with exterior fuel lines and a relocated fuel water separator to make the most of the available chassis space, according to Transfer Flow.  The system comes with a full installation kit to get the heavy-duty tank mounted and ready for the road.  “Our goal when engineering the new 60-gallon tank was to increase the fuel capacity as much as possible while maintaining the durability and integrity of the truck,” said Todd LaPlant, director of engineering.  “The 2017 Ford Super Duty is an elite truck that is unbelievably capable, so it will easily be the truck of choice for many who are towing fifth wheels and those needing to get into the backcountry.  We’ve designed a replacement tank that extends both the luxury and brute strength of the vehicle even further.”
