Most people probably don't know the name PACCAR but they've surely seen Peterbilt, Kenworth and DAF. Those are three of the biggest medium and heavy duty truck brands on the market . The smoky exhaust from those big diesel trucks has surely annoyed most drivers and pedestrians at some point in time. PACCAR produces trucks under those brands and others that are used around the world. The company has announced plans to meet 2010 diesel emissions requirements by adding exhaust gas recirculation (EGR) and urea injection systems (SCR) to their engines. The 2010 standard will require an eighty percent reduction in NOx emissions compared to 2007 levels, so PACCAR is following the same path chosen by a number of automakers including Mercedes-Benz, BMW and Hyundai-Kia. PACCAR is getting suppliers lined up to ensure that urea solution is readily available to operators when the new engines roll out in 2010.
