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 the MZ-CD or CiTD. The Ford of Britain/PSA and joint-venture for the production of the DLD/DV was announced in September 2001. 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.[1]
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 Mazda3.
Officially, there are three 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.[2]
The Duratorq DLD-414 (or DV4) is a 1.4 L (1398 cc) straight-4 turbo-diesel. Output is 68 PS (50 kW; 67 hp) at 4500 rpm and 160 N⋅m (118 lb⋅ft) at 2000 rpm.
The DV4 is available in two versions:
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 75 PS (55 kW; 74 hp) to 130 PS (96 kW; 128 hp) at 3500 rpm to 3750 rpm and 230 N⋅m (170 lb⋅ft) to 300 N⋅m (221 lb⋅ft) at 1750 rpm.
The PSA variant has a DOHC 16-valve design, while the Ford variant has a SOHC 8-valve design. The DV5 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.
The DLD-416 (or DV6) is a 1.6 L (1560 cc) UK-built version used by Ford, Fiat, Volvo, PSA, Mini, Suzuki 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 16-valve DOHC was reduced to 8-valve SOHC and called DV-6C/DV-6D.
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 8-valve 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 115 PS (85 kW; 113 hp) at 3800 rpm and 250 N⋅m (184 lb⋅ft) at 1850 rpm. In August 2002, a version appeared in the Ford Focus with reduced power, producing 99 PS (73 kW; 98 hp) at 3850 rpm and 240 N⋅m (177 lb⋅ft) at 1750 rpm. Early 2005 saw the more powerful unit's torque boosted to 280 N⋅m (207 lb⋅ft) at 1900 rpm, with power remaining unchanged at 115 PS (85 kW; 113 hp).
The latest versions of the DLD-418 were released with the 2007 Ford Mondeo. One has an output of 99 PS (73 kW; 98 hp) at 3850 rpm and 280 N⋅m (207 lb⋅ft) at 1800 rpm. The more powerful variant has an output of 125 PS (92 kW; 123 hp) at 3700 rpm and 320 N⋅m (236 lb⋅ft) at 1800 rpm.
