As you know, IC Bus and our parent company, Navistar, Inc., will meet 2010 EPA emissions requirements with our customer-friendly solution: MaxxForce® Advanced EGR. As you know, IC Bus and our parent company, Navistar, Inc., will meet 2010 EPA emissions requirements with our customer-friendly solution: MaxxForce® Advanced EGR. As I sat down to write this week's email, I thought about the name "Advanced EGR" and how well it fits our 2010 compliant engines.Among the enhances of our MaxxForce engines in 2010 is their advanced ability to minimize heat and soot to maintain engine life. Did you know that the MaxxForce Advanced EGR engines, in all IC BusTM brand buses will maintain their current service life? (The MaxxForce 7 engine B50 life is 375,000 miles and the MaxxForce DT engine B50 life is 450,000 miles.)
Some people may question how we can do this using Advanced EGR. Their questions usually revolve around heat or soot.
Regarding heat, our engineers have worked diligently to ensure that our engines optimally manage the heat of combustion. Our 2010 MaxxForce engines do this better than previous generations. EGR heat is not in the engine - it is in the EGR cooler. In fact, although we are flowing slightly more EGR we are also cooling that flow more so any additional heat is dealt with in the cooling system, which is larger. And, we have upgraded our EGR cooler construction and provided a unique, ultra-efficient coolant flow circuit.

As for soot, which is simply unburned fuel, our other technology advances take care of that. The high-pressure fuel system, twin turbos, piston bowl, and multiple injection events make a more efficient burn; therefore the opportunity to make soot is greatly reduced.
Without question, our MaxxForce Advanced EGR technology takes these things into account so that our current engine life is maintained. After all, if you had to worry about reduced engine life, we couldn't really call it "advanced," could we?
Once again, with our 2010 compliant MaxxForce Advanced EGR engines maintaining their current service life, IC Bus continues to take the burden of 2010 compliance off our customer.
