Abstract

Two catalyst formulations using resistively heated metal monolith substrates were evaluated for the application of exhaust emission catalysts on an M100 neat methanol-fueled vehicle. The active catalyst formulations were palladium: cerium (Pd:Ce) and a base metal formulation. The catalysts were evaluated at low mileage in two modes: Resistive heating applied to the substrate during portions of the cold-start and hot-start transient segments of the test cycle (Federal test procedure); and No resistive heating applied to the substrate during the driving cycle. The test vehicle was also driven in the baseline, or no-catalyst mode, to obtain engine-out emission levels for comparison. Resistively heating the palladium catalyst provided a substantial emissions control benefit over the non-resistively heated catalyst mode. The base metal catalyst showed a slight improvement in emissions when the catalyst was resistively heated.
