Study of Hydrogen Additive High EGR Combustion for Gasoline Engine with Fuel Reformer

燃料改質器付きガソリンエンジン用水素添加高EGR 燃焼の研究

To improve the fuel economy, high EGR combustion stability is improved by the addition of hydrogen with fast burning speed in air-fuel mixture. In order to realize on-board hydrogen gas generation, an engine reformer system assembled with a reformer catalyst and a fuel injector on the external EGR line is explored. Reformed gas is consisted with not only hydrogen but also CO, CH₄ and so on, therefore the effect of reformate gas component except for hydrogen for high EGR combustion performance is one issue of this system. This effect is clarified by the result of single cylinder engine test with simulated reformate gas and real reformate gas.高EGR 燃焼の安定改善手段として燃焼速度の高い水素を混合気へ添加する方法が有効である.そこで水素を排気ガスを用いた改質反応によって生成し,直接導入する方法について研究を行っている.今回,排気ガスとガソリンを用いた燃料改質実験における水素生成性能とその水素によるEGR 限界向上効果の確認結果について報告する.
