Emissions Control Challenges for Compression Ignition Engines

As emission standards continue to evolve, it is clear that future engine control strategies will involve the integration of combustion optimization, fuel refinement and advanced exhaust after-treatment technologies. The West Virginia University (WVU) Center for Alternative Fuels Engines and Emissions (CAFEE) continues to engage the challenge of future regulation in a multi-pronged approach, investigating advanced combustion regimes, alternative fuels, and next-generation emissions control technology. Results presented herein summarize recent regulatory challenges for compression ignition engines and discuss future pathways.
