[edit] 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.
[edit] 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.
[edit] Description of Work
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.
