WARRENVILLE, Ill. — Navistar says its EPA2010 engines are in the final stages of high altitude, high temperature testing and will be ready for roll-out on time.
The company is using advanced EGR (exhaust gas recirculation) in its International MaxxForce engines, while all its competitors are instead using exhaust aftertreatment in the form of selective catalytic reduction (SCR).
“We are on track with our strategy of 2010 emissions compliance through the use of our EGR-only solution and are ahead of schedule in some cases,” said Jack Allen, president of Navistar’s North American truck group. “With our line-up of MaxxForce Advanced EGR engines, we’re delivering a simple and straightforward solution that places the responsibility of emissions compliance on us, the manufacturer, not the customer.”
Over the past 18 months, Navistar says it has extensively tested its 2010 engines in the lab and on the road.
“As we reach the final stages of our testing and validation processes, we’re excited about our progress in bringing to market some of the cleanest and most energy-efficient diesel engines ever produced,” said Ramin Younessi, group vice-president, product development and business strategy. “Completing the validation phase of our test engines is a major milestone, but our work isn’t done yet. As with any new engine program, up until the day we build that first truck, we will continue to fine-tune our engines, make the necessary adjustments, test and validate to ensure our customers have the performance and reliability they expect.”
Current testing is underway in Nevada and the mountains of Colorado, the company says. Navistar says it has more than 60 test vehicles on the road today and by the time the new engines are rolled out, they will have accumulated millions of driving miles in real-world conditions.
