Compression Ratio and Catalyst Aging Effects on Aqueous Ethanol Ignition, Phase II Grant uri icon



  • During the second year of this project, we will complete calibration of a vaporizer in the Combustion Laboratory. The vaporizer will be used first to add water to gaseous fuels, thus taking advantage of data we have acquired to study the effect of water on surface reactions. We will begin experiments with aqueous ethanol-oxygen mixtures. In our engine laboratory we will acquire data on the effect of compression ratio on the catalytic ignition of ethanol-water fuel blends with our Cooperative Fuel Research (CFR) engine, and install an eddy dynamometer purchased in Phase I. With Automotive Resources Incorporated (ARI), our demonstration van will be available for public outreach. We will continue to make our laboratories available to other researchers and instructors in the Center for Clean Vehicle Technology. Outcomes of this work will include: 1) key information (aging effects, light-off temperature, heat generation rate, and a simple catalytic surface heat generation model) needed for engineering timing models used to optimize igniter design; 2) design specifications and performance predictions for engine designs that are optimized for igniter systems; 3) improved regional awareness of ethanol fuel; and 4) infrastructure improvements that enhance our competitiveness in state and federal funding programs.
