DALLAS, Tex. — Cummins officials at the Great American Trucking Show announced the company’s 2007 on-highway engines are performing well in field tests.
Field evaluations are underway, on schedule and providing valuable information, the company reports. The 2007 engines use exhaust gas recirculation (EGR) along with diesel particulate filters to reduce emissions.
The joint OEM field tests are being run across a wide range of applications, duty cycles and geographic regions, according to officials. Cummins began testing pre-production 2007 engines last year and expanded its testing program to include real-world fleets earlier this year.
“Cummins jointly selected customers with our OEM partners that run more challenging duty cycles for the aftertreatment. This allows us to gain valuable real-life data on how the Cummins particulate filter is operating so we can further optimize the integrated package,” said Dr. Steve Charlton, Cummins executive director and technical leader, 2007 Heavy-Duty Program.
The field tests are monitored using data acquisition computers that continuously sample and analyze data. Drivers are also required to complete daily checklists monitoring various fluid levels such as oil and coolant.
“The field test evaluation program is providing an unprecedented amount of information when compared to previous programs. Some of our test applications run 24 hours a day, seven days a week. We’re extremely pleased with the performance of the Cummins Particulate Filter,” said Charlton.
