IRVINE, CA –Isuzu Commercial Truck of America announced that it intends to use selective catalytic reduction (SCR) to achieve the 2010 standards for emissions of nitrogen oxides (NOx) by diesel engines.

SCR is an aftertreatment technology that involves injecting a water-based solution containing urea into the hot exhaust stream of an engine.

The new technology will be used in Isuzu engines sold in its trucks in the U.S. under the Isuzu, Chevrolet, and GMC trademarks.

Isuzu intends, however, to continue to use both a diesel particulate filter (DPF) and exhaust gas recirculation (EGR) in certain models.

According to Shaun Skinner, executive vice president and general manager, “Isuzu has been developing after treatment technology in Japan for many years. We’ve studied different systems, and found SCR to be highly reliable under even the most extreme applications and conditions.”

The company recently revealed that it intends to pursue “an aggressive offensive” to increase its medium-duty market share in North America, according to Transport Topics.
