Diesel Emissions Reduction Requirements

EPA 2010 is the final phase of the Environmental Protection Agency's (EPA) plan to assure that medium-duty and heavy-duty trucks run cleaner by the year 2010. In fact, EPA 2010 standards require that NOx levels from new trucks be reduced to almost zero.

Faced with strict and well defined engine emission regulations, the trucking industry has worked hard to meet these important environmental regulations, while ensuring that maximum fuel efficiency and engine performance was not sacrificed.

In order to meet the new EPA 2010 requirements, most diesel engine manufacturers are using Selective Catalytic Reduction (SCR) technology. The SCR system uses diesel exhaust fluid to convert NOx emissions into nitrogen and water vapor – two harmless and natural components of the air we breathe.

SCR technology, and the integral role diesel exhaust fluid plays, has been successfully used in Europe for years and has proven to provide near-zero NOx emission levels while delivering improved fuel economy and engine reliability.

What is NOx?

Oxides of Nitrogen (NOx) are an exhaust element that contributes to acid rain, smog and greenhouse gas levels. This environmental pollutant is a by product of the high temperature diesel combustion process. The hotter the combustion temperature, the more NOx is created.
