Research Interests
Internal combustion engines are machineries those principles have been invented more than 100 years ago. Still today, they are being modified with several newly developed technologies in order to improve energy efficiencies or emissions characteristics. In my laboratory, we are investigating about alternative fuels, such as biofuels (Palm oil, Rape-seed oil, Jatropha oil, etc.) and chemical substances (Dimethyl ether, Ethanol, etc.) with operations of practical engines. Also, characteristics of fluidity and atomization of those fuels are analyzed with experimental instruments originally made by our laboratory. Moreover, we are trying research works by use of Marine Engine Plant Simulator (Engine Room Simulator) which is used for maritime education and training.

Message for Students
Internal combustion engines used widely in the world are required to be innovated to prevent the global warming and preserve the energy sources.
What are significances of existence for internal combustion engines whilst alternative power sources, such as a fuel cell, are being developed?
I'm thinking that one of them is ability to obtain large power. For instance, it is necessary to use jet engines (continuous combustion type engine) to float and traverse heavy air planes with passengers and cargos. So called electric propulsion ships are also using diesel engines (intermittent combustion type engine) for electric generations.
In this background, I suppose that it is important to develop internal combustion engines that can reduce burdens to environments and apply sustainable energy sources.
