The reduction of carbon emissions while maintaining power and performance in internal combustion engines (ICE) is critical for reductions of global emissions of greenhouse gases. While current engines have gone some way towards achieving lower emissions, savings are limited due to the materials construction of engine components. To further improve on emissions, materials which make up the critical components (piston, ring, connecting rod, etc.) need to improve to enable re-designing of components for significant emissions savings. This paper will outline some of the potential material alterations which enable a significant emission saving while maintaining or increasing power by enabling re-designing of critical components. Results of engine testing on a commonly available IC engine will be presented showing significant reductions in emissions and power improvements over the standard baseline model by changing materials allowing re-designing of components.
