Mazda Z engine
From Wikipedia, the free encyclopedia
The Mazda Z engine family is an evolution of the B family. It started with 2.0 L and 2.3 L variants found in the Mazda3, Mazda6 and Ford Ranger. For 2004, Ford dropped its own Zeta Zetec engines in favor of Mazda's, naming the resulting engine the Duratec 20 and Duratec 23.
Confusingly, Mazda also sells Ford's Sigma Zetec (which is unrelated to both the Zeta and Mazda Z family) as the MZI. The MZ-CD diesel is also unrelated to the rest of the Z family.
The Z5, ZL/ZM, and MZR are DOHC 16-valve water-cooled engines.

[edit] 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 75.3 mm and 83.6 mm. The Z5 was a totally new design but didn't succeed and the development was discontinued. It's the only Mazda engine with these piston dimensions.
[edit] ZL/ZM
The ZM engine is also known as the Z6, it is the evolution of the Z5 with round intake and exhaust ports.
The 1.5L (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. The ZL makes more power, in its high end ZL-VE form, then its larger displacement version due to variable valve timing on the intake cam (s-vt).
Applications:
- 1998-2002 Mazda Familia
[edit] MZR
- Main article: Mazda MZR engine
The versatile MZR is Mazda's latest straight-4 engine. Ford was inspired by Mazda through this engine, and also sells the engine as the Duratec 23. The MZR family features a special long intake manifold for added torque, S-VT continuous variable valve timing, and a stainless steel 4:1 exhaust header.
The DISI turbocharged MZR was on the Ward's 10 Best Engines list for 2006 and 2007.
