First produced in 1929, the Minor engines' family has an advanced design for the period and sports steel cylinders, aluminum heads and overhead valves, with identical bore and stroke of and , respectively. Typical power ratings varied from 105 hp to 160 hp.〔Gunston 1989, p.174.〕 After Walter concentrated on the turbine powerplants only, the production of piston engines has been transferred to the Avia company that further developed the family, bringing fuel injection, as the Avia M-137 and M-337. Nowadays the smallest of the family, the four-cylinder carburetted Minor, is produced by a small company in the Czech Republic, while the M337 was available from the LOM Prague. ==Variants== ;Minor Sc.: ;Minor M 337 ;Minor 4-I: ;Minor 4-II: ;Minor 4-III: ;Minor 6-I: ;Minor 6-II: ;Minor 6-III: ;Minor 12 1-MR:〔(【引用サイトリンク】title=National Technical Museum, Prague )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Walter Minor」の詳細全文を読む スポンサード リンク
