Ford DLD engine
The Ford DLD engine is an automobile engine family - a group of compact straight-4 Diesel 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.
The straight-4 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:
The 1.4 L DLD-414 is generally non-intercooled
The 1.5 L derived from the 1.6 L
The 1.6 L DLD-416 is always intercooled
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.
