終戦までの我が国舶用内燃機関の技術を顧みて

抄録

As everybody knows, the present stage of technical level in Japan, regarding to production, design, research and development of the marine engines field, is remarkably high. In order to sound the origin of those technical progress, it has been investigated on the technical history of marine internal combustion engines in Japan as one of the projects of the Committee of Marine Engineering History in Japan in MESJ as one of their projects.
This paper gives an essential materials compiled from the above studies.
It was the first step of marine internal combustion engines in Japan that kerosene oil engines and gas engines began to be applied to small river boats in about 1898 and then proceeded to be applied to fishing boats. In the next step, hot bulb engines were introduced in 1903 and then widely used. Following to them, Diesel engines were introduced in 1907 and installed to many kinds of ships, i.e. to coast service ships, fishing boats, ocean going vessels and also navy ships.
There were a quite number of memorable technical improvements attained in Japan on the various matters of marine internal combustion engines.
