Cummins Inc. has honored nine employees with its highest technical award for their contributions to significant technological advances that have benefited the company.

The Julius Perr Innovation Award is presented annually in honor of the inventor or co-inventor of 80 U.S. patents. Perr joined Cummins in 1958 after fleeing Communist Hungary. He retired from Cummins in 1997 as vice president of fuel systems, and died in 2005.

The recipients are scientists and engineers who developed critical advances in filtration and aftertreatment products. They each received a trophy-like award.

“In the spirit of Dr. Perr’s rich legacy, these inventors have demonstrated that the Cummins commitment to innovation and technology leadership continues to grow through our development of products that help enable our customers’ success,” said Jennifer Rumsey, vice president and chief technical officer. “Our ability to develop differentiated products, information and technologies to meet future challenges will continue to set us apart from the competition.”

Beginning in 2007, the United States Environmental Protection Agency required diesel particulate filter exhaust aftertreament in order to meet ‘07 emission requirements.

Serviceability of these systems is necessary because of the need to clean the particulate filters from ash and other contaminants during their life.

Engineers Patrick Klein, Jeff Sedlacek and David M. Grimm — all who work in Wisconsin — developed a compact, serviceable aftertreatment system that made it shorter and easier to package, and limited impact on the places where parts joined together. This enabled packaging of the particulate filter in key customer applications in the United States in 2007.

What was learned from their project also was applied to the Global Single Module Next Generation Aftertreatment Platform, which Cummins is launching in 2017.

Engineers Stephanie (Faber) Severance, Brad Smith, Brian Schwandt, Chris Holm, Gerard Malgorn and Peter Herman developed a means of separating oil mist from crankcase gasses to protect the engine and the air people breathe.

This flexible, scalable method removes oil mist from crankcase ventilation gases across a wide range of temperature conditions engines operate in. The product lasts the entire life of the engine with no service, and assisted Cummins in meeting EPA emissions regulations.

This invention allowed Cummins to offer a product with high performance, low-cost, service-free filtration, compact packaging and high reliability, and it replaced more expensive serviceable technology that was larger in size and higher in cost.

This invention has been applied to a variety of engine platforms from the ISF2.8 to the QSK95.

Severance works at the Cummins Tech Center in Columbus, and Smith also is based in the city at Cummins’ new downtown offices along Third Street. Schwandt, Holm and Herman work in Wisconsin, while Malgorn works in France.
