Compression Ratio and Catalyst Aging Effects on Aqueous Ethanol Ignition
During this phase of our transportation fuels research, we continue our work to advance catalytic plasma torch technology. Our three-pronged approach includes basic research, engine work, and demonstration vehicle support. Our basic research will determine the ignition temperatures and heat release rates of reacting flows exposed to heated “fresh” and “seasoned” Pt catalysts over a wide range of fuel-oxygen equivalence ratios and fuel-water blends. In our engine lab we will study the effect of compression ratio on the catalytic ignition of ethanol-water fuel blends with our recently renovated CFR engine. In collaboration with our industry partners at Automotive Resources Incorporated, our demonstration van will be upgraded, maintained, and displayed in public forums. An important by-product of our work is stewardship of laboratory resources that enable other research projects in the Center for Clean Vehicle Technology as well as educational programs associated with engine technology.
Outcomes of this work will include 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, design specifications and performance predictions for engine designs that are optimized for CPT systems, raising regional awareness of the potential for ethanol vehicles, and infrastructure improvements that greatly enhance our competitiveness in state and federal funding programs
