It was used from front-wheel drive economy applications to the turbocharged full-time 4WD 323 GTX and rear-wheel drive Miata as well as numerous other models. The Mazda B-series is a "non-interference" design, meaning that breakage of its timing belt does not result in damage to valves or pistons, because the opening of the valves, the depth of the combustion chamber and (in some variants) the shaping of the piston crown allow sufficient clearance for the open valves in any possible piston position. ==B1== B1 - (68.0x78.4 mm) - came only as a SOHC 4-valve. It was available in the 1987-1989 Mazda 121 and later model Kia Sephia in European and Asian markets. A fuel-injected variant was used in select European market 1991-1995 Mazda 121s 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「Mazda B engine」の詳細全文を読む スポンサード リンク
