MAZDA ZM-DE

The Mazda Z-series is a smaller inline 4-cylinder gasoline engine ranging in displacements from 1.3L to 1.6L. 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 chain. The block of the 98-02 Z5, ZM 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. 1.6 L (1598 cc, 105 hp) ZM-DE (78x83.6 mm) The ZM engine, driven by a timing belt, is also known as the Z6, it has an identical bore, yet slightly longer stroke than the ZL as well as a revised head with round intake and exhaust ports. It has exactly the same bore and stroke as the previous generation B6. The 1.5 L (1498 cc, 130 hp) ZL-VE and 1.6 L (1598 cc, 105 hp) ZM-DE are closely related engines with an equal bore (78mm) and share some major parts. The ZL has a stroke of 78.4 mm whilst the ZM has 83.6 mm.
