Navistar launches MaxxForce 2010 emissions education campaign

Navistar Inc., the maker of International brand commercial vehicles and MaxxForce brand diesel engines, has launched an education campaign aimed at clarifying issues surrounding 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 nitrogen oxide (NOx)-reduction technology paths.

For 2010, suppliers of diesel-powered heavy commercial vehicles — except one — plan to offer North American customers all-new, add-on after-treatment 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 using advanced EGR, without additional aftertreatment, on its MaxxForce-powered International brand vehicles, IC Bus brand schoolbuses, and Workhorse brand RV chassis.

Navistar has pursued its in-cylinder with advanced EGR technology path for most of the decade, with a goal of providing the best solution in terms of fuel economy, performance, and overall ownership costs. Perhaps most importantly, the in-cylinder solution keeps emissions compliance with the OEM, whereas SCR puts the burden of compliance on vehicle owners. MaxxForce 2010 products provide a diesel-fuel-only solution, a stark contrast to SCR vehicles which require extra hardware, controls, and a second fuel (urea); 2010 MaxxForce-powered vehicles will require only diesel and operate just as today's commercial vehicles do.

Navistar's in-cylinder solution with advanced EGR uses four key technologies — advanced high-pressure fuel injection, advanced air management, an optimized combustion strategy, and proprietary electronic calibrations — to meet the new EPA standards without sacrificing operating costs or performance.

The MaxxForce 2010 campaign will run throughout 2009. Additional information is at
