The fundamental concern for the environment, and the people who live in it, has driven Isuzu to be one of the world’s leaders in “green” diesel technology. After many years of development and testing, Isuzu has determined that Isuzu diesel trucks will use Selective Catalytic Reduction (SCR) technology to meet the new EPA 2010 heavy duty vehicle emissions standards.

What is the EPA 2010 Emission Standard?

The purpose of the 2010 emissions standard is to further reduce NOx emissions from heavy duty engines. Simply stated, NOx is a generic term for oxides of nitrogen (primarily NO and NO2). These oxides are produced in the cylinder of an engine during the high temperatures of combustion. Starting January 1st, 2010, engine NOx emissions must be reduced by 85% over current levels. This new level of reduction results in a cumulative NOx reduction of 99% from 1974 levels, and clearly makes diesel engines clean, green technology. The implementation of this standard will have an overwhelmingly positive impact on our environment and on the air that we breathe in the future.

Why Use Selective Catalytic Reduction (SCR) Technology?

After many years of extensive testing and study, Isuzu has determined that SCR is the most cost-effective, reliable, and fuel-efficient way to meet the very strict EPA 2010 emissions standards. The ability to meet strict requirements affordably without compromising vehicle performance, operating cost and uptime is essential. In commercial trucking, the ability to reduce emissions to near-zero levels while also delivering fuel savings and improved engine reliability distinguishes SCR as the preferred emissions control technology that is as good for business as it is for the environment.

These considerations have led Isuzu, as well as the majority of other diesel engine and truck manufacturers, to select SCR as the technology of choice to meet EPA 2010 emissions standards. Read more...
