They are the evolution of the cast-iron block B-engine. The Z-engine has 16-valves operated by dual overhead camshafts, which are in turn driven by a timing belt. The block of the 98-02 Z5, Z6 and ZL engine is cast iron same as the earlier B series of engines. Other Z engines have aluminum alloy block and head, with cast-iron cylinder liners. The block features split upper and lower block assembly for added strength and rigidity, special long intake manifold for added torque, S-VT continuous variable valve timing, and a stainless steel 4:1 exhaust header. As of 2011, Mazda will cease to develop the Z-engine, to be replaced by the SkyActiv ''P-engine''. ==Z5== The 1.5 L (1489 cc, 92 hp) Z5-DE was used in the 1995-1998 Mazda Protegé, Mazda Lantis (Astina) and in Mazda Familia Neo (1994–1997). Bore and stroke were and . The Z5 engine was the first iteration for all newer Z-series lines of Mazda engines. The Z series of engine are totally new design but based on B-series. The block, block internals and oil-pan are similar to the B series of engines but the DOHC head is a completely new design. The block is cast iron, the oil-pan is a 2-piece design with an upper aluminum and lower stamped steel, piston oil squirters are standard. The cylinder head was a compact design with round intake and exhaust ports. JDM versions produce and . 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 Z engine」の詳細全文を読む スポンサード リンク
