Development of EGR Reforming Catalyst for Gasoline Engine with Fuel Reformer
燃料改質ガソリンエンジン用EGR 改質触媒の開発
Stability of high EGR combustion is improved by the addition of hydrogen. So, the authors developed "EGR reforming catalyst" which produces hydrogen rich gas from fuel by using heat and water vapor of exhaust in order to realize on-board hydrogen generation. It was found that main issue to realize EGR reforming catalyst was a suppression of catalyst deterioration under the exhaust gas condition. The authors found out that water activation of the catalyst decreased with carbon deposition on the catalyst surface due to sulfur compounds adsorption. Catalyst degradation was inhibited by the improvement of water activation of the catalyst using rare earth component.混合気に燃焼速度の速い水素を添加すると希薄燃焼安定性が改善されるため,高EGR 燃焼が可能になり,燃費を向上できる.そこで,オンデマンド水素ガス生成をオンボードで実現するため,EGR ガスの顕熱と水蒸気を用いてガソリンを改質して水素リッチな改質ガスを生成する“EGR 改質触媒”の開発を行った.
