Abstract |
The major portion of hydrocarbon and carbon monoxide emissions measured from a catalyst-equipped gasoline vehicle over the Federal Test Procedure (FTP) cycle are generated during the cold start and warmup of the catalyst. These emissions are difficult to control because engine-out emissions are high and catalytic converters have low conversion efficiency during their warm-up phase of operation. A resistively heated metal monolith catalyst has been evaluated by EPA Motor Vehicle Emission Laboratory on a methanol-fueled vehicle. Results from this previous testing indicated the feasibility of the concept of a resistively heated metal monolith substrate as a quick light-off catalyst support. The report describes the evaluation of such a catalyst on a gasoline-fueled vehicle. The vehicle was tested at 72-74 deg F ambient test cell conditions and at 20 deg ambient 'cold-room' conditions. |
