Cummins Prepared for ’07 emissions
Cummins says its heavy-duty and mid-range diesel engines are ready to meet new stricter emission standards set for 2007 and that its ISX and ISM Class 8 engines with ’07 emissions configuration will be in limited production by the fourth quarter of 2006.
The engines will continue to rely on the company’s core exhaust gas recirculation technology introduced in its 2002 engine models, including its Variable Geometry Turbocharger. But to meet the 2007 emissions standard, which requires greater reductions of carbon and nitrogen oxides, the company unveiled a diesel particulate filter and a new system that will help catch and filter crankcase emissions.
“With more than 300,000 cooled-EGR engines on the road, and over 30 billion miles of experience, we are confident in the customer advantages provided by our 2007 engines and emissions solution,” said Ed Pence, Cummins vice president and general manager of heavy-duty engine business. Pence made the announcement at the Technology and Maintenance Council’s annual meeting in Tampa, Fla.
Manufactured by the company’s Fleetguard division based in Nashville, the Cummins Particulate Filter works with the engine to reduce emissions. Exhaust passes through a ceramic wall-flow filter coated in palladium and platinum. Particulates trapped there are oxidized during regeneration and exit as less harmful carbon dioxide and oxygen.
The filter uses exhaust heat to create regeneration. Typically this occurs as a truck is running down the highway and will not affect a vehicle’s operation, Cummins engineers said. In some cases the system will require active oxidation, which means the engine will automatically pump small amounts of diesel fuel to assist the process.
Drivers won’t notice when the trap is oxidizing particulates, said Steve Charlton, Cummins executive director of heavy-duty engineering.
The particulate filter will last the life of the engine, although some maintenance will be required to remove ash every 200,000 to 400,000 miles. Cummins will deploy a filter-cleaning machine to its dealers and approved maintenance providers starting in 2007.
Trucking Sees AARP as Driver Source
The American Trucking Associations and the Truckload Carriers Association are among 20 groups in a range of industries joining to collaborate on recruiting and retaining baby boomer employees.
The associations have joined the Alliance for an Experienced Workforce, an effort to help employers create workplaces that attract and keep employees ages 50 and older. Another alliance goal is ensuring that workers 50 and older are prepared to accept the skills and jobs in demand and increase the importance of this demographic group.
The Alliance was developed from a National Advisory Council formed to advise AARP on workplace and workforce strategies.
More than 25 million workers will be eligible for retirement in the next decade, a good population to tap to mitigate the driver shortage, said ATA President Bill Graves.
“Motor carriers consistently have employed qualified workers over age 50 because of their proven track record as safe, professional drivers with well-developed judgment skills, strong work ethics and sound sense of responsibility,” Graves said. “We hope that this effort will facilitate a healthy dialogue between motor carriers and mature workers interested in a truck driving career.”
