79252 As environmental regulations become increasingly stringent, there is mounting pressure on automobile manufacturers to substantially lower unburnt hydrocarbon emissions. This will require monitoring the hydrocarbon content in the exhaust with more accuracy than currently possible using the two oxygen sensor system. This requirement is especially important during start-up conditions, which account for more than 90% of hydrocarbon emissions. This project will develop a robust, miniature hydrocarbon sensor that can detect hydrocarbons in automobile exhaust, with excellent sensitivity to hydrocarbons, minimal cross-sensitivity to exhaust gas constituents (e.g. CO, CO2, NOx, SO2), and fast response time (< 1 sec). In Phase I, a number of key experiments, including a demonstration of minimal cross-sensitivity to specific exhaust gas constituents, will be carried out to demonstrate feasibility. Phase II will focus on sensor miniaturization/integration, prototype development, on-board testing, and demonstration. Commercial Applications and Other Benefits as described by the awardee: The new hydrocarbon sensors should be small and inexpensive enough to be installed for on-board monitoring and emissions control applications in automobiles, providing significant benefit to the environment and quality of life. The technology also should allow manufacturers to reduce catalyst loadings and life-cycle engine degradation.
