Ford ecoboost 4 cylinder

Reciprocating internal combustion engine

The MazdaL-series is a mid-sized inline 4-cylinder gasoline pistonengine designed by Mazda as part of their MZR family, ranging in displacement from 1.8 to 2.5 liters. Introduced in 2001, it is the evolution of the cast-iron block F-engine. It was co-developed with Ford, who owned a controlling stake in Mazda at the time. Ford uses it as their 1.8 L to 2.5 L Duratec world engine and holds a license to develop engines based on the L-series in perpetuity.

The L-engine uses a chain-driven DOHC, 16-valve valvetrain with an all-aluminum block construction and cast-iron cylinder liners. Other features include fracture-split forged powder metal connecting rods and a one-piece cast crankshaft.

Other features are intake cam-phasing VVT, VTCS, VICS, a stainless steel 4:1 exhaust manifold and a lower main bearing cage for increased block rigidity. Direct-injection is available on the 2.0-liter LF-VD and the DI Ford truck ecoboost engine.
