Research Abstract

Generally, a premixed-charge spark-ignition system is used for the hydrogen-fueled internal-combustion engine. However in this combustion system, the flame propagation speed of the hydrogen mixture is excessively high, so that an operating condition is restricted. In this study, in order to control the combustion of the hydrogen mixture, non-homogeneity of fuel-air mixture concentration is applied. In the near stoichiometric region, the combustion dominated by the flame propagation speed, and in the rich or lean region the combustion dominated by mixing. Here, in order to form the non-homogeneous mixture, a high-speed unsteady-jet was used, and this system was used for a real engine.
