The Ford DLD engine is an automobileengine family - a group of compact inline-fourDiesel engines developed jointly by Ford of Britain and the automotive-diesel specialist PSA Group (Peugeot/Citroën). 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.[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 Mazda 3, calling it the MZ-CD or CiTD.
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.[2]
DLD-414
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:
One, a SOHC 8-valve design, uses a KKK KP35 turbocharger but no intercooler. This is the same turbocharger as the Renault K9K Diesel. It is Euro 3 compliant, but will receive a Diesel particulate filter from 2006 to make it Euro 4 compliant. In Ford, Mazda, and most PSA applications it uses a Siemens SID804 or SID802 common rail injection system. The PSA Variant in the 2005-2008 Citroën C1/Peugeot 107/Toyota Aygo 1.4 HDi uses the Siemens SID805 common rail injection system with a lower power output compared to other applications to compensate for the weaker 5-speed manual transmission used in these models. [3] In some PSA applications a Bosch common rail system is used. [citation needed]
A second version uses a DOHC16-valve design, with an intercooled variable-geometry turbocharger. This engine uses Delphi Corp.'s DCR1400 common-rail injection system. This derivation will no longer be built from 2006, as it will not be able to comply with the EURO4 regulations.
The Duratorq DLD-415 (or DV5) is a 1.5 L (1499 cc) straight-4 turbo-diesel. 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 DLD-416 (or DV6) is a 1.6 L (1560 cc) UK-built version used by Ford, Volvo, PSA, Mini and Mazda.
The 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
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 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.
