Navistar said it is in the final test stages of its 2010 MaxxForce engines and will be ready to meet the new Environmental Protection Agency’ (EPA) emissions requirements when they go into effect on Jan. 1, 2010.
“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 lineup 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.”
Navistar is choosing to meet the EPA requirements through advanced exhaust gas recirculation (EGR) in combination with credits the company has achieved though previous engines outperforming EPA mandates.
“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 vp-product development & 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.”
The manufacturer said it completed cold-weather testing in Minnesota and is now doing final validation testing at high altitude and high temperatures in Nevada and the mountainous regions of Colorado. More than 60 test vehicles are currently on the road, Navistar said.
The EGR approach does not require the use of urea or aftertreatment equipment, Navistar said, eliminating weight from the vehicle. The MaxxForce engines will meet CARB NOx best achievable control technology (BACT) certification.
“We strongly believe emissions compliance should be the responsibility of the manufacturer, not the customer,” said Allen. “Accountability for meeting emissions requirements should not rest on the actions of the driver, the reliability of very complex technologies, or even the impact of severe weather conditions. The development and testing of our EGR solution for 2010 is in advanced stages and we are confident that our engines will deliver the performance, reliability and low operating costs our customers demand.”
