The 2010 emission standards for heavy-duty engines have
established a limit for oxides of nitrogen (NOX) emissions of
0.20 g/bhp-hr, a 90% reduction from the previous emission
standards. However, it is projected that even when the entire
on-road fleet of heavy-duty vehicles operating in California is
compliant with the 2010 NOX emission standards, the upcoming
National Ambient Air Quality Standards (NAAQS) requirements for
ambient particulate matter and ozone will not be achieved in
California without further significant reduction in NOX emissions
from the heavy-duty vehicles.

The main goal of this project was to demonstrate that modern
heavy duty engines can achieve a target of 0.02 g/bhp-hr for
tailpipe NOX emission, which represents a 90% reduction from the
2010 standard, with currently available control technology. An
additional goal of the project was that the final configurations
of engine and aftertreatment systems should be consistent with a
path toward meeting current and future heavy-duty greenhouse gas
(GHG) and fuel economy standards.
