The Mazda L-series is a mid-sized inline 4-cylinder gasoline engine designed by Mazda, ranging in displacement from 1.8L to 2.5L. Introduced in 2001, it is the evolution of the cast-iron block F-engine. The L-series is 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. 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 header and a lower main bearing cage for increased block rigidity. Direct-injection is available on the 2.0 L 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, using Ford's own manifold and engine control systems. Ford plans to use the L-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 - an extensively revised evolution of the Mazda L-engine. At this time, Ford will be the only manufacturer still using the Mazda L-engine design.
The 1.8 L (1,798 cc (109.7 cu in)) version has an nearly- 83.0 mm (3.3 in) bore and a 83.1 mm (3.3 in) stroke. Output is 125 hp (93 kW) at 6000 rpm with 122 lb·ft (165 N·m) of torque at 4250 rpm.
In 2001, Ford introduced its first European Ford engine to use gasoline direct injection technology, badged SCi (Smart Charge injection) for Direct-Injection-Spark-Ignition (DISI). The range will include some turbocharged derivatives, including the 1.1-litre, three-cylinder turbocharged unit showcased at the 2002 Geneva Show. The 1.8 L was the first European Ford engine to use direct injection technology, badged SCi for Smart Charge Injection. This appeared in the Mondeo in 2003 and is today available on the 2.0 L engine as well.
