Navistar Inc. on Tuesday, Jan. 6, launched an education campaign aimed at clarifying its stand on 2010 emissions technologies. Its “MaxxForce 2010” campaign – including customer seminars, public webinars and trade advertising – addresses the fuel economy, cost-of-ownership and operational impacts of the competing approaches to NOx-reduction technology paths.
For 2010, most suppliers of diesel-powered heavy commercial vehicles plan to offer North American customers all-new add-on aftertreatment systems using SCR (selective catalytic reduction) in addition to EGR (exhaust gas recirculation). The lone exception is Navistar, which will continue to use an in-cylinder solution utilizing advanced EGR, without additional aftertreatment, on its MaxxForce-powered International brand vehicles, IC Bus brand school buses and Workhorse brand RV chassis.
“We need to be aggressive in giving the industry all the facts,” says Jack Allen, president of Navistar’s North American Truck Group. Recent industry surveys show that fleet managers and truckers are not clear on the options for 2010 or the relative merits of competing emissions-reduction technologies, Allen says.
Navistar says it has pursued its in-cylinder with advanced EGR technology path for most of the decade. The company says its “MaxxForce 2010” products provide a diesel-fuel-only solution, in contrast to SCR vehicles that require extra hardware, controls and urea.
“All MaxxForce-powered 2010-model trucks and buses will fully comply with EPA emissions standards on January 1, 2010,” Allen says. “We’ve worked hard to provide the most customer-focused solution, and now we want customers to know how we’ve done it and how it benefits them.”
Navistar says its in-cylinder solution with advanced EGR utilizes four key technologies – advanced high-pressure fuel injection, advanced air management, an optimized combustion strategy and proprietary electronic calibrations – to meet the new U.S. Environmental Protection Agency standards without sacrificing operating costs or performance. The Warrenville, Ill.-based company’s “MaxxForce 2010” campaign will run throughout 2009.
