Abstract:
Our goal is to develop combustion and engine control strategies
allowing for the maintenance of superior fuel economy while
meeting clean air constraints. The use of after-treatment
devices, coupled with aggressive regeneration strategies, allow
for low soot and low NOx. The task is a formidable challenge however,
considering several different issues such as cylinder to cylinder
combustion variations, hydrocarbon makeup, and after treatment
device selection.

Clean
Diesel Technology Test Cell -
Premixed Combustion in a Multi-Cylinder Diesel Engine
Background:
A
contributing member of the General Motors Collaborative Research
Laboratories - Engine Systems Research (GMCRL-ESR),
the Clean Diesel Technology test cell focuses on developing
emission regulations-compliant diesel engines for 2007 and beyond.
Researchers:
Dennis Assanis
Zoran Filipi
Stani Bohac
Andrew Ickes
Will Northrop
Sponsors:
General Motors |
| What
work is being done:
Specific research tasks for this test cell currently include the
characterization of cylinder to cylinder variations when running
novel modes of low soot and low NOx emissions, development of
lean NOx trap regenerative combustion strategies, and speciation
of diesel engine exhaust in both conventional combustion modes
as well as regenerative combustion modes. |
