The Truck Manufacturers Association and truck makers Freightliner, International, Mack and Volvo recently showcased the fruit of two years of research into tractor and trailer aerodynamics, co-funded by the U.S. Department of Energy.

Freightliner worked on fine-tuning truck mirrors in its wind tunnel, while International worked primarily on tractor-trailer gap, trailer side treatments and rear treatments designed to minimize air wake. Mack also worked on tractor-trailer gap enclosures, side skirts and a boat tail at the trailer rear; and Volvo worked on improving airflow under the vehicle and reducing the interaction between the turbulence generated by the underside and that generated in the tractor-trailer gap.

“Implementation of the results of this research ultimately could save nearly 1 billion gallons of fuel annually,” says Robert Clarke, president of the Truck Manufacturers Association, which organized the project.

DPFs not simple devices
During a recent visit to Cummins’ Emission Solutions facility near Madison, Wis., members of the press were shown what goes into manufacturing diesel particulate filters (DPFs). From forming coiled steel, adding a filter substrate and catalyst, to final assembly, the process is more complex than I would have guessed.

Cummins’ facility in Mineral Point, Wis., which employs nearly 350 people, began in 1947 as Nelson Muffler, a four-employee operation that worked out of a small space in a former county garage. Today’s facility – now about 72,000 square feet – was constructed in 1974 and expanded in 2006 to enable the production of DPFs.

The plant has manufactured more than 1.5 million medium- and heavy-duty diesel oxidation catalysts, and well over 10,000 medium- and heavy-duty DPFs.

In November, we asked what the acronym WABCO stands for. We had a lot of correct responses – Westinghouse Air Brake Company – but the first came from Ed Miraglia, teaching assistant for the Putnam Northern Westchester Board of Cooperative Education Services, based in Yorktown Heights, N.Y.

Ed gets an elegant CCJ pen and Air Brake Book, and you can, too, if you’re the first to send the correct answer to this month’s Puzzler to prichards@ccjmagazine.com, or if you send in a Puzzler of your own and we use it.
