24 Jun 08. Since January 2007, when the latest EPA emissions standards went into effect, Navistar® Engine Group has produced more than 300,000 emissions-compliant diesel engines for medium- and heavy-duty commercial trucks and buses. These MaxxForce brand engines equipped with integrated system technologies including advanced fuel, air, combustion and electronic-calibration strategies have been well received by International® dealers and proven successful by owners and operators. “We have been very pleased with the performance of our 2007 emissions-compliant engines,” said Jack Allen, president, Navistar
Engine Group. Testimonials from owners and operators have indicated
positive results with regard to key value drivers including improved fuel
economy, performance, reliability and durability. The success of 2007-compliant MaxxForce engines validates the company’s path of full 2010 emissions compliance using proven in-cylinder NOx-reduction solutions rather than add-on aftertreatment systems. “Our approach to NOx reduction not only helps the environment, but also helps International Truck customers, who will not be burdened with increased operating, service and maintenance requirements associated with additional aftertreatment,” Allen said.
