Jim Park was a CDL driver and owner-operator from 1978 until 1998, when he began his second career as a trucking journalist. During that career transition, he hosted an overnight radio show on a Hamilton, Ontario radio station and later went on to anchor the trucking news in SiriusXM's Road Dog Trucking channel. Jim is a regular contributor to Today's Trucking and Trucknews.com, and produces Focus On and On the Spot test drive videos.
Daimler Trucks’ Inspiration
LAS VEGAS -- What happens in Las Vegas is supposed to stay in Las Vegas, but that certainly not the case with Daimler Trucks' recently introduced Inspiration Truck. It's the autonomous commercial vehicle that has taken the world by storm. Literally. Daimler Trucks invited more than 200 journalists from four continents to cover the event, and stories have appeared in over 500 newspapers and on TV news shows all over the globe. Today's Trucking was there too, of course. And we had our chance to ride in the truck. We were not allowed to drive it at this event because it requires some driver certification, which there wasn't time to procure. We did come back from the launch event with this video of our test drive, with Equipment Editor Jim Park in the right-hand seat.
Dana’s Dual Range Disconnect
First revealed at the Mid-America Trucking Show in March, Dana's Dual Range Disconnect drive axle system offers the fuel savings benefit of a downsped 6x2 drivetrain and the performance benefits of conventional 6x4 setup with a mid-range axle ratio. The key word here is disconnect. While running at speeds up to about 54 mph, the system functions as a 6x4 with torque going to all four wheels for optimum traction. It also runs at a 3.10:1 ratio for better performance and startability. Above 54 mph, the interaxle driveshaft disengages, leaving the driving to only the forward drive axle. Interestingly, the axle ratio of the forward axle is 2.26:1, which lowers engine rpm and in effect creates a downsped drive train. The benefit, of course, is better fuel economy resulting from a 300-400 rpm drop in engine speed.
Volvo’s Adaptive Gearing
Volvo Trucks has put a new spin on an old powertrain management strategy; by locking out top gear on its I-Shift overdrive transmission, drivers can pull loads efficiently in 11th gear (direct drive) and still get the performance they want. When running empty, sensors in the transmission and the suspension sense the lower weight and unlock 12th gear, which is overdrive. The truck can cruise home in at a very low engine speed at a higher road speed. This video explains how Adaptive Gearing works and features more excerpts from an interview with Gene Brice, co-owner of Idaho Milk Transport. Adaptive Gearing is ideally suited to tank fleets that run about half their miles empty, and when you hear Brice's fuel economy with this system, you'll be asking if it can work for you too. And don't forget to check out our Focus On report on Volvo's Adaptive Loading system to see what it has to offer.
Terror by Truck: It’s happened again
At about the same time North Americans were awaking to the news that President Trump had lobbed 60 Tomahawk cruise missiles onto a Syrian air base an apparent terrorist stole a truckload of beer and crashed it through the front of a Swedish department store. The death toll in the Stockholm department store crash stands at four at the time of this writing.
The Quest for Uptime: It begins with Preventive Maintenance checks
We're learning. We are doing a better job at keeping trucks out of the shop and out on the road earning money, but it's been a steep learning curve. Ever since the first Diesel Particulate Filters appeared in 2007, fleets have been struggling to diagnose problems and make the necessary repairs. One of the greatest hurdles has been confusing messages and sometimes misleading information. Various sensors are often the culprit, but for the technicians working through the problem the troubleshooting exercise was at first new and unfamiliar.
IN PRINT — Power Plays: A look at 2017 engines
Most North American heavy-duty diesel engine manufacturers rolled out substantially revamped engines to meet the U.S. Environmental Protection Agency's (EPA's) 2017 Greenhouse Gas emissions regulations. Those rules were the final step for diesel engines in Phase 1 of the grand carbon dioxide reduction plan. Engine makers now have a few years to figure how to meet the next - and even more restrictive - round of fuel-efficiency improvements, which come into force for Model Year 2021 engines.
Will new U.S. administration scuttle GHG rules?
WASHINGTON, DC -- As the final days of the Obama administration tick away, those opposed to some of the president's environmental initiatives are looking at ways to undermine the intent of the rules, or even to strike them from the books. With Republicans in charge of the House, the Senate and the White House, you could say the stars are uniquely aligned for just this sort of action. President-elect Donald Trump has already made it clear that he opposes and intends to undo some of those rules. Could Phase 2 of the Greenhouse Gas rules be on that list? "This has big potential for those who would like to strike any carbon regulation or fuel efficiency standards from the trucking industry," said American Trucking Associations vice president, energy and environmental counsel Glen Kedzie, in remarks he made during a GHG Phase 2 webinar hosted by ATA's Technology and Maintenance Council on January 5. Kedzie suggested there are three options open to the new administration: a legal challenge, an executive order from the president, or working through the Congressional Review Act to roll back the rule.
Bridgestone building SuperTire for SuperTruck II
NASHVILLE, TN -- Engineers at Bridgestone are working to develop super-low-rolling-resistance tires for the next Cummins/Peterbilt SuperTruck project. The goal is a tire with a 30% reduction in RRC (Rolling Resistance Coefficient), which equates to a 6% improvement in fuel economy and still meets industry expectations for wear and retreadability.
Canada’s approach to Electronic Logging Devices (ELDs)
The days of paper logbooks are numbered for southbound fleets, with the U.S. preparing to mandate Electronic Logging Devices (ELDs) by the end of 2017. Canada originally led the way in discussions to set standards for the devices. Now we're playing catch-up. With trucking associations backing their use, it may only be a matter of time before ELDs are mandated for domestic fleets as well.
