Recent Results from Prototype Vehicle and Emission Control Technology Evaluation Using Methanol Fuel

This paper details the results of testing certain M1OO neat methanol prototype vehicles and emissions control technology with methanol vehicle applications. Two M100-fueled prototype vehicles utilizing 4 valve per cylinder technology and lean operating strategies were evaluated for emissions and fuel economy profiles. Gasoline equivalent fuel economies for the methanol vehicles were calculated and compared with fuel economy profiles from comparable gasoline-fueled vehicles. Palladium: cerium and base metal catalysts on resistively heated metal monolith substrates were also evaluated for use as methanol-fueled light-duty vehicle catalysts.
