Mazda L engine
Encyclopedia
The Mazda
L-series is a mid-sized inline 4-cylinder gasoline engine ranging in displacements from 1.8L to 2.5L. Introduced in 2001, they are the evolution of the cast-iron block F-engine
. This engine is designed by Mazda
and is also used by Ford as their 1.8L to 2.5L 'Duratec' world engine.
The L-engine uses a chain-driven DOHC, 16-valve
valvetrain with an all-aluminum block construction and cast-iron cylinder liners. Also featured are intake cam-phasing VVT
, VTCS, VICS
, a stainless steel 4:1 exhaust header and a lower main bearing cage for increased block rigidity. Direct-injection is available on the 2.0L LF-VD and the award-winning (DISI) turbocharged L3-VDT engine introduced in 2006 for the Mazdaspeed
lineup of vehicles.
As of 2010, Ford is introducing a GDI
turbo variant of the Mazda LF engine design as the EcoBoost
2.0L. They have developed their own manifold and engine control systems for use with the direct-injected
, turbocharged EcoBoost. Ford plans to use the L-engine, as well as the Z-engine
, well into the future for their EcoBoost and Duratec 4-cylinder generations. As of 2011, Mazda will cease to develop the L-engine, to be replaced by the SKYACTIV P-engine. At this time, Ford will be the only manufacturer still using the Mazda L- and Z-engine designs.

2.5L (L5-VE)
Introduced in non-North American markets for the MY2008 and North American markets for MY2009, the 2.5L L5-VE is an updated, bored and stroked version of the L3-VE 2.3L. The 2.5L (2488 cc) L5 engine has an 89.0 mm (3.50 in) bore and a 100.0 mm (3.94 in) stroke, with a compression ratio of 9.7:1. The standard crankshaft is forged-steel with eight counterweights like the turbocharged DISI 2.3L L3-VDT. To increase durability of the bore, Mazda uses a 4340 steel-molybdenum alloy material for the cylinder liners. This offers enhanced high-heat tolerance as well as reduced friction. The increased stroke of 100 mm (3.9 in), up from 94 mm (3.7 in) of the L3, allows a higher final-drive ratio resulting in lower-RPM while cruising to increase fuel economy. It produces 170 bhp at its 6000 rpm redline (168 bhp in PZEV trim) and 167 lbft of torque at 4000 rpm (166 ft·lbf in PZEV trim). EPA fuel economy estimates for the US market are 21 city/30 highway for the all-new 2009 Mazda6 equipped with the 5-speed automatic transaxle. 6-speed manual versions of the same car achieve 1 fewer mpg in the same EPA city/highway tests (20/29).Ford has developed an Atkinson cycle
