14 Honored With Perr Innovation Award
THE JULIUS P. PERR INNOVATION AWARD IS PRESENTED ANNUALLY TO CUMMINS EMPLOYEES FOR THEIR CONTRIBUTION TO SIGNIFICANT TECHNOLOGICAL ADVANCES BENEFITING THE COMPANY.
In 2015, 14 scientists and engineers were honored for developing critical, robust solutions to reduce diesel emissions for challenging engine duty cycles.
"These inventors and their novel ways of approaching and solving problems have added to the Cummins legacy of innovation and technology leadership,” said Rich Freeland, President and Chief Operating Officer at Cummins. “Dr. Perr’s commitment to this legacy and to the success of our customers helped us become a market leader.”
Here’s a look at the 2015 winners:
THERMAL MANAGEMENT OF DIESEL PARTICULATE FILTERS
The ability to control exhaust temperatures within a desired temperature window has been a daunting challenge facing engine manufacturers. Cummins’ engineers Linsong Guo, Tim Frazier and Morgan Andreae developed geometry-turbocharger and fuel-injection strategies to control aftertreatment temperatures while optimizing fuel consumption and avoiding damaging engine conditions.
CONTROLLING DIESEL EXHAUST TEMPERATURES
Emissions reductions and associated aftertreatment systems required significantly improved controls compared to previous diesel engine control strategies. Jennifer Rumsey and Tom Dollmeyer were able to improve diesel fuel economy and reliability through their approach which used inverted virtual sensor technology.
Dan Baker, Steve Bellinger, Melissa Dye, John Mulloy, Pat Shook, Joan Wills and Steve Wills were honored for their contributions to develop robust and effective diesel particulate filter regeneration strategies. These technologies improved diesel fuel economy while assuring that the optimum particulate filter cleaning was obtained at the proper time.
PREVENTION OF CARBON DEPOSITS ON AFTERTREATMENT
Carbon deposits can build up on the front surfaces of catalysts in diesel exhaust sometimes referred to as “face-plugging.” Conrad Simon and Tom Yonushonis were honored for the development of a novel inlet surface coating that aided in the removal of deposits at low temperature exhaust conditions.
