Mazda Z Engine
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, 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.
Famous quotes containing the word engine:
“The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.”
—Ralph Waldo Emerson (1803–1882)
