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. At this time, Ford will be the only manufacturer still using the Mazda L-engine design. == 1.8 L (L8-DE, L8-VE) == The 1.8 L () version has an nearly-square bore and a stroke. Output is at 6000 rpm with 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).〔(Ford of Europe showcases most extensive range ever at the 2002 Paris Show ), Media.ford.com, 2002-09-26.〕 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. The SCi engines were designed at Ford's Cologne, Germany facility and are assembled in Valencia, Spain. The SCi engine is paired with a specially designed six-speed manual transmission. European 1.8 L and 2.0 L ''Duratec HE'' engines are built at the Valencia Engine Plant in Spain. Duratec FFV is a flex fuel version of the 1.8 L Duratec-HE modified to run on E85 fuel. 1.8L Focus C-Max and Focus Mk II versions use a drive-by-wire throttle to improve responsiveness. Ford's versions are rated at at 6000 rpm and of torque at 4500 rpm with a 10.8:1 compression ratio.
