Even as those attending the 2017 Technology & Maintenance Council (TMC) annual meeting kicked the tires and examined the electronics of today's ever-evolving commercial trucks, a big political gathering occurred back in the nation's capital – one that is going to impact the trucking industry in a variety of ways.

">The Cummins X15 Efficiency Series diesel has won the Truck Writers of North America's 2016 Technical Achievement Award.
The award was presented during an awards luncheon at the American Trucking Associations Technology & Maintenance Council's annual meeting in Nashville, Tenn.
Cummins redesigned its ISX15 to meet 2017 federal greenhouse gas and fuel economy requirements, and introduced two models called X15 Performance and X15 Efficiency. The Efficiency version employs an Atkinson Cycle in its valve action that adds fuel efficiency important to fleet managers, said John Baxter, a freelance technical writer, former mechanic and a member of the TWNA panel. That caught the attention of his colleagues in the voting.
“The engine won for its advanced combustion design that includes a little-used Atkinson Cycle, and other features,” explained Jim Park, chairman of the TWNA awards committee and Heavy Duty Trucking equipment editor. “It beat out four other finalists who had previously topped a pool of 15 candidates for the award. A panel of industry journalists from Canada and the U.S. debated and voted over a period of several weeks.”
The 14.9-liter diesel gains 3% in fuel efficiency over the preceding model, the ISX15, through improvements to air-handling, combustion efficiency, reduced parasitic losses and advanced electronics, Proctor said. Maintenance should cost 40% less than previous engines over five years, according to Cummins.
“The engine's valve events are modified so that compression is slightly limited, allowing for greater-than-normal expansion during the power stroke that follows,” he explained. “That means that the gases expand to 20 times their volume at the pistons' top center by the time they are released, as opposed to standard expansion factors in the range of 15-17 to 1. Allowing the burning gases more room to expand captures energy ...Read the rest of this story

" width="350" height="259">Denso Products announced that it will begin accepting orders for its new line of PowerEdge diesel particulate filter and diesel oxidation catalyst replacement products for heavy-duty trucks and equipment in March.
The all-makes original equipment replacement program features 60 DPF part numbers covering more than 260 OE-quality parts and 7 DOC part numbers for heavy-duty on-road and off-road trucks and equipment. The PowerEdge line was announced at Heavy Duty Aftermarket Week in January and is being produced in partnership with Clean Diesel Technologies, a global manufacturer of vehicle emissions control systems.
The companies plan to expand the line with an additional 20 DPF and 15 DOC part numbers later this year.
“Denso is excited to partner with CDTi to meet the growing demand for OE-quality diesel aftertreatment products in the heavy-duty trucking and equipment industry,” said Frank Jenkins, senior manager of Denso's heavy duty marketing group. “CDTi is a clean-tech company that shares our commitment to product reliability and durability, rigorous safety and performance standards, innovation, customer service and environmental stewardship.”
PowerEdge aftermarket DPFs and DOCs match or exceed the emissions control performance and benefits of OEM replacement units when installed in 2007 model year and newer heavy-duty diesel equipment, according to Denso.
The turnkey DPFs and DOCs are approved for horizontal, vertical, and dual installation and backed by a two-year, unlimited mileage warranty. All products are designed and manufactured in North America.
