Come January, when new truck diesel emissions regulations take effect, Detroit Diesel will be ready with updated versions of its DD13, DD15, DD16 engine families. Similar to updated or new truck diesels from General Motors, Ford and Cummins, the motors from Detroit Diesel will incorporate a selective catalytic reduction (SCR) system. That means they will use a urea injection system in the exhaust stream to convert NOx emissions into water and nitrogen.
Detroit Diesel is owned by Daimler Trucks NA and is able to draw on the German parent company’s extensive experience with SCR. Nonetheless, Detroit Diesel has accumulated over 25 million test miles proving out its implementation. In addition to the SCR, DD has optimized the rest of the engine as well to reduce overall fuel consumption by five percent, which will surely be a welcome improvement to truck operators.
