Abstract
Advanced diesel combustion modes offer the promise of reduced
engine-out particulate and nitrogen oxide emissions, thereby reducing
the demand on post-combustion emission control devices. In this
activity, a light-duty diesel engine was operated in conventional and
advanced combustion modes. The advanced combustion modes investigated
correspond to both clean (i.e., low PM and low NOx) and
clean efficient combustion. The low-NOx, low-PM mode is
considered an intermediate condition and the low-NOx, low-PM
efficient mode is referred to as high efficiency clean combustion
(HECC). Particulate and gaseous emissions were analyzed during all of
these experiments. The detailed exhaust chemistry analysis provided
significant new information to improving our understanding of these
modes as well as identifying potentially important unregulated
emissions. |
