O.S. Engines
From Wikipedia, the free encyclopedia
O.S. Engines is a Japanese model engine manufacturer.
The company was founded in 1936 by machinist Shigeo Ogawa (or in more traditional Japanese, "Ogawa Shigeo") for the production of model steam engines. The name of the firm could have either originated from the traditional Japanese family-name-first tradition being the source of the "OS" name, or from the firm's actual Japanese name, "Ogawa Seisakusho". At the suggestion of American buyer Paul Houghton, Ogawa tooled up for his first gasoline-powered engine, the 1.6 cc O.S. Type-1 of which 200 units were produced and exported under the brand name, "Pixie." After World War II, Ogawa Seiki expanded to produce the MAX line of engines, which won acclaim for their performance and durability.
In 1976, OS pioneered the field of modern four stroke glow plug ignition model engines with the "FS-60" 10 cm3 displacement exposed valve gear engine, and has been one of the top producers of four-stroke glow plug ignition model engines worldwide ever since.
Today, O.S. Engines produces a much larger line of engines that includes the only Wankel rotary aircraft engine which was first introduced in 1970.
The 1980s brought increasing competition, which increased across the 1990s and into the 21st century. O.S. is now a leading manufacturer of single and multi-cylinder model aircraft engines ranging from the small .10 LA two-stroke to the FF-320 four-stroke "giant-scale" flat four-cylinder and the FR5-300 five-cylinder giant-scale radial.
O.S. engines in current production include the .18 TM, the .18 TZ, the .46 AX and many others. O.S. also makes required accessories for their engines including glow plugs, exhausts and air filters.
