EGR for EPA-2010? Navistar Says it's all in the Programming

Truck Talk
Volume 2 Number 8

There are two sides to every story, as we all know. On the last episode of Truck Talk we heard from the CEOs of four of the five engine manufacturers planning to use selective catalytic reduction exhaust aftertreatment to meet EPA's 2010 emissions reduction mandate. We've also devoted considerable time to the SCR strategy in general here on Truck Talk. It's now EGR's turn.

Navistar claims and has maintained right from the start that EGR is the way to go for EPA 2010. Exhaust gas recirculation coupled with carefully managed high-pressure fuel injection works, Navistar say, and in fact, one of the company's big-bore engines will be certified for EPA 2010 in the very near future. That move will come well in advance of the January 1 deadline but no one will notice – except EPA.

Navistar calls it Advanced EGR, and on this episode of Truck Talk, Tim Shick, the director of business and product strategy for the Navistar engine group joins me to explain how his company will meet EPA's strictest reduction targets ever using just EGR and high-pressure fuel injection.
