Single Drive Axles Could Reduce Your Fuel Bill
Even with the best basic specs, additional fuel savings will come from substituting a single drive axle for the standard tandem axle drive system.
Is More Frequent Overhead Maintenance Worth the Trouble?
Adjusting overhead valves on heavy-duty diesels is a routine maintenance item subject to benign neglect in many of today’s fleets. But factory engineers are split on the importance of frequently setting overheads.
Diesel Engine Makers Need to Innovate to Meet Stricter NOx Emission Standards
As state and federal clean-air regulators move forward with plans to further reduce nitrogen oxide and particulate matter emissions from commercial trucks, diesel engine makers are exploring new technologies to meet those targets in the coming years.
Achates’ Engine Brings Power, Lower Emissions
Achates Power of San Diego has developed a two-stroke truck diesel that has two crankshafts linked to two opposed pistons facing each other in a common cylinder.
Considerations for Hydrogen-Electric Trucks
Hydrogen will likely end up as the dominant fuel for longhaul trucks one or more decades from now, according to experts at familiar component suppliers and truck manufacturers. Nikola Motor Co. agrees, as one of the first entrants into this arena, with a whole new vehicle architecture.
Ducted Fuel Injection Shows Promise for Diesel
Researchers have developed a promising yet surprisingly simple modification to diesel engines that could hold the key to reducing the complexity, maintenance, and size and weight of emission aftertreatment systems.
Taking a Look Under the Hood of Electric Trucks
The introduction of electric-powered trucks represents a new frontier for the transportation industry, but this new breed of commercial vehicle will not be completely unfamiliar to fleets and maintenance shops.
One Major Fleet’s Experience Testing Electric Trucks
Fleets that have been at the forefront of testing electric trucks are gaining insights into how these new vehicles perform in real-world freight operations.
Diagnostics Could Ease Adoption of Electric Trucks
The advance of diagnostic programs has improved maintenance and uptime for diesel trucks, and it appears the same will be true for electric-powered vehicles.
Rear Axle Ratios Are Still Moving Downward
Downspeeding saves fuel, and with aerodynamics and tires continuing to improve, truck manufacturers are experimenting with still lower rear axle ratios.
