Fuel Consumption Improvement by Engine EGR Reforming with Ethanol-Blended Gasoline Steam Reforming

Abstract

Engine EGR reforming was examined with a goal of improving the fuel consumption of engines burning ethanol-blended gasoline. The catalyst carriers of Rh catalyst were examined and optimized by using a flow reactor. The improved “carrier of ceria” is the most suitable. And engine EGR reforming was examined by an experimental engine. With pure ethanol, engine EGR reforming was possible at lower temperature compared with gasoline, and the fuel consumption was improved. With E85, the hydrogen in reforming gas was increased with the optimized catalyst.
