caption_attribution_description: English: 2009 Ford Focus SES coupe (North America) engine bay, featuring the 2.0 L Duratec 20
context_page_description: The Mazda L-series is a mid-sized inline 4-cylinder gasoline engine designed by Mazda as part of their MZR family, 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 manifold 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 turbocharged L3-VDT engine introduced in 2006 for the Mazdaspeed lineup of vehicles.
  In 2010, Ford introduced 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.
context_section_description: The 2.0 L (1,999 cc (122.0 cu in)) version has 10.0:1 compression ratio, an 87.5 mm (3.44 in) bore and it shares the 83.1 mm (3.27 in) stroke of the 1.8 L. Changes to the engine include switching from a cast aluminum to a reinforced plastic intake manifold and from Sequential multi-port fuel injection to gasoline direct injection.
  Ford's version is rated at 107 kW (143 hp; 145 PS) of power at 6000 rpm and 185 N⋅m (136 lb⋅ft) of torque  at 4500 rpm with a 10.8:1 compression ratio. This engine is also used by Volvo, called B4204S3 (or B4204S4 as Flexifuel engine capable of running on E85).
  On the 2007 Focus, output is 136 hp (101 kW; 138 PS) at 6000 rpm with 136 lb⋅ft (184 N⋅m) of torque at 4250 rpm.  The 2007 Focus with the PZEV emissions package produces 130 hp (97 kW; 132 PS) at 6000 rpm with 129 lb⋅ft (175 N⋅m) of torque at 4000 rpm. On the 2008 Focus, output is 140 hp (104 kW; 142 PS) at 6000 ;rpm with 136 lb⋅ft (184 N⋅m) of torque at 4250 rpm. The 2009 Focus had 143 hp (107 kW; 145 PS) when equipped with manual transmission due to a higher flowing exhaust system.  The 2008 Focus with the PZEV emissions package produces 132 hp (98 kW; 134 PS) at 6000 rpm and 133 lb⋅ft (180 N⋅m) of torque at 4250 rpm.
  Mazda's LF-VD version was equipped with Direct Injection Spark Ignition (DISI) and a higher compression ratio for improved efficiency in the JDM and EDM markets. It produces 148 hp (110 kW; 150 PS) at 6500 rpm and 187 N⋅m (138 lb⋅ft) of torque at 4000 rpm.
  In 2011 Ford started selling the third generation Ford Focus in North America which comes with an updated version that utilizes direct injection and  Ti-VCT. These features, along with an increased compression ratio of 12.1:1 allow the engine to generate 160 hp (119 kW; 162 PS) at 6000 rpm and 146 lb⋅ft (198 N⋅m) of torque at 4250 rpm. This version is referred to as the "Duratec 20."
  The Ford Duratec 20 engines are built in Dearborn, Michigan, United States, and Chihuahua, Mexico, with some being built by Mazda in Hiroshima, Japan.
  The plastic intake manifold on early versions of the 1.8 and 2.0 has a major fault due to poor-quality materials. The manifold has swirlplates mounted on a square shaft at the aperture where it mounts to the cylinder head. Early four-cylinder Duratec engines can be ruined when the swirlplates break off and enter a cylinder. Most cases are of single swirlplates but also the shaft can wear and break. Early signs of this fault are evidenced by a ticking noise emanating from the front of the engine. This can occur as early as 25K miles, with failure typically occurring after about 90,000 miles.
  A turbocharged Ford EcoBoost version was introduced in 2010.
