Old Engines in Japan 1930s SATO's SEMI DIESEL ENGINE 2hp Part 1

SATO's SEMI-DIESEL ENGINE (Hot bulb engine) 2hp Around 1933 Manufacturer : SATO Company Manufacturer's Location : Higashiizumocho, Matsue-shi, Shimane, Japan This is a hot-bulb engine-type engine made at pre World War II. Because a magneto was unnecessary as for the semidiesel engine, it was made in some Japanese makers at the time. This engine burns a charcoal fire on the cylinder head, and heats hot bulb. This Engine is not my thing. I observed this engine at 2012 SUISHO-no-YU Spa engine show.
