The complex lineage of Ford's versatile Duratorq diesel engine range
In short: Introduced in 2000, the Duratorq name covers a vast family of diesel engines. From the 'Puma' units in London taxis to high-performance variants in Jaguars, this range has powered everything from compact cars to heavy-duty commercial vehicles through strategic partnerships and constant evolution.
The Duratorq range is not a single engine but a diverse collection of powerplants developed through various collaborations. A significant portion of the family stems from a 1998 joint venture between Ford and PSA (Peugeot Citroën), resulting in the DLD family of inline-four engines. These units, known as HDi by Citroën and Peugeot, have been utilized across multiple brands, including Mazda, Volvo, and Mini. In contrast, other variants like the 2.0, 2.2, and 2.4-liter ZSD engines—codenamed 'Puma' during development—were produced at Ford's Dagenham plant in East London.
The evolution of these engines reflects shifting regulatory landscapes. For instance, the 1.4L DLD-414 engine required a diesel particulate filter in 2006 to meet Euro IV standards. Meanwhile, certain 16-valve DOHC versions were phased out in 2006 because they could not comply with these same Euro IV regulations. Even the 1.8L DLD-418 presents a curious case: while Ford officially classifies it within the DLD family, it is technically a development of the older Endura-D engine and is more accurately part of the Endura family.
Technological leaps have defined the range's progression. The transition from the older Endura-D to the Duratorq marked a significant jump in performance; for example, the 2.0L ZSD-420 offered 115 PS and 280 N⋅m of torque, a vast improvement over its predecessor. Later iterations, such as the 2.0L TDCi introduced in 2005, utilized advanced third-generation common rail injection systems with pressures reaching 1,800 bar. These systems use piezo-electric injectors with seven apertures per nozzle, allowing for up to six injections per cycle to ensure more complete and uniform combustion.
