Local Cummins employee wins annual award

A local Cummins, Inc. employee is among eight honored with the Dr. Julius P. Perr Innovation Award.

Among the recipients is Doug Owens, Columbus, who was honored for the controls and engine architecture that improved diesel particulate filter regeneration while minimizing deposits, the company said.

The patented technology addressed the Exhaust Gas Recirculation cooler fouling by modifying the exhaust manifold and fuel systems controls. The invention modifies the exhaust manifold into separate exhaust flow paths.

For Cummins inline six-cylinder engines, this provided an isolated EGR exhaust path and a dosing exhaust path while being transpart to turbocharger exhaust flow.

The fuel system controls limit hydrocarbon dosing necessary for particulate filter regeneration to the front three engine cylinders while maintaining overall engine fueling controls and diagnostics.

Nearly 2 million Cummins midrange engines use the patented system, Cummins officials said. The technology is implemented in heavy-duty production and the Cummins Global 6 architecture.

Global 6 is the term used for many of the markets considering adopting the Euro VI standards, the company said. Because of its success in Europe in controlling in-use emissions from heavy-duty vehicles, Euro VI is seen as a good starting point for other regions looking to define the next stage of emissions regulation, the company said.

The Perr award is the company’s highest technical award, presented annually to employees for contributions that made significant technological advances benefiting the Columbus-based Fortune 200 company.

Also winning the Perr Innovation Award were Mark Wieczorek, Terry Shults, Bill Haberkamp and Jonathan Sheumaker, all based in Cookeville, Tennessee, and Barry Verdegan, Chris Holm and Brian Schwandt, based in Stoughton, Wisconsin.

They were honored for developing nanofibers used in a wide range of Cummins Filtration filters.

The nanofibers have exceptional filtration properties when applied within a composite filter system, the company said. Their development of advanced manufacturing technologies enabled Cummins to become one of the world’s largest producers of nanofiber.

The introduction of ultra-low sulfer fuel with stringent emissions standards coupled with high-pressure common rail fuel systems necessitated improved fuel water separation technologies, the company said. Cummins Filtration developed a new filter media using proprietary nanofiber manufacturing technology to improve water separation from diesel fuel.
