The engine is of Mitsui B & W's type, fitted with direct coupled supercharging blowers, of the latest supercharging system and capable to develop 6, 000 B.H.P. at 115 r.p.m. for normal full load and proved to develop 6, 900 B. H. P. for over load, which is an epochmaking figures in the world for a single acting Diesel engine. In this paper the characteristic construction of the engine and the principle of the new system of supercharging is described and some are also picked from those of bed tetsts.
