Ford DLD engine
The DLD is the name for an automobile engine family – a group of compact inline-four Diesel engines, involving development by Ford of Britain and/or PSA Group (Peugeot and Citroën), and also Mazda where it is called MZ-CD or CiTD. The Ford of Britain/PSA joint-venture for the production of the DLD/DV was announced in September 1998. Half of the total engine count are produced at Ford of Britain's main plant at Dagenham, England and at Ford's Chennai plant in India, the other half at PSA's Trémery plant in France. The  inline-four engines are sold under the DuraTorq TDCi name by Ford, and as the HDi by Citroën and Peugeot. Mazda also uses the Ford-made DLD engine in the Mazda2 and the Mazda 3. Officially, there are two families of engines in the range: Ford later added their unrelated 1.8 L DLD-418 engine to the DLD family, though it is properly part of the Ford Endura-D engine family. In 2012, Ford added the 1.5-litre, closely derived from the 1.6-litre engine. DLD-414. The Duratorq DLD-414 (or DV4) is a 1.4 L (1398 cc) straight-4 turbo-diesel. Output  is at 4500 rpm and at 2000 rpm. The DV4 is available in two versions: DLD-415. The Duratorq DLD-415 (or DV5) is a 1.5 L (1499 cc) straight-4 turbo-diesel developed by Ford and PSA Group. Output is to at 3500 rpm to 3750 rpm and to at 1750 rpm. The DV5 has a SOHC 8-valve design, with an intercooled variable-geometry turbocharger (for example, Garrett GT1544V), and with Diesel particulate filter is Euro 6.2 compliant. It is based on the DV6 SOHC engine. DLD-416. The DLD-416 (or DV6) is a 1.6 L (1560 cc) UK-built version used  by Ford, Volvo, PSA, Mini and Mazda. The first DV6 has a DOHC 16-valve design, with an intercooled variable-geometry turbocharger (for example, Garrett GT1544V), and with Diesel particulate filter is Euro 5 compliant. In 2011 the 16V DOHC was reduced to 8V and only SOHC and called DV-6C/DV-6D DLD-418. The Duratorq DLD-418 is a 1.8 L (1753 cc) intercooled common rail diesel engine. It is only a DLD by name, since it is completely unrelated to the 1.4/1.6 units, and is derived from Ford's own 1.8 8v Endura-D engine that saw service through the 1980s  and 1990s. However, Ford considers it part of the DLD family, as evidenced by the official "DLD" name. The Endura-D was heavily revised and updated with a variable-vane turbocharger and a Delphi high-pressure common rail injection system and relaunched in 2001 as the DuraTorq TDCi, with the original engine being rebadged 'DuraTorq TDDi'. The output of the original 2001 unit is at 3800 rpm and at 1850 rpm. In August 2002, a version appeared in the Ford Focus with reduced power, producing at 3850 rpm and at 1750 rpm. Early 2005 saw the more powerful unit's  torque boosted to at 1900 rpm, with power remaining unchanged at . The latest versions of the DLD-418 were released with the 2007 Ford Mondeo. One has an output of at 3850 rpm and at 1800 rpm. The more powerful variant has an output of at 3700 rpm and at 1800 rpm. See also:
