Ford Duratorq is the marketing name of a range of Ford diesel engines first introduced in 2000 for the Ford Mondeo car model.
The first design, codenamed "Puma" during its development, replaced the older "Endura-D" diesel engine which had been around since 1984. Commercial versions of the Puma unit replaced Ford's older "York" diesel engine used in the Transit, and many other manufacturers' vehicles. Due to a development and co-operation programme, other unrelated units in this range have been developed by PSA Peugeot Citroën. The PSA engines are available in vehicles from Peugeot and Citroën (PSA Group), and Jaguar, Land Rover, Volvo and Mazda (Ford's Premier Automotive Group as was) vehicles.
ZSD ("Puma")
Codenamed Puma during development, these Ford 2.0 litre, 2.2 litre, and 2.4 litre engines are called ZSD. They are produced at Ford's Dagenham plant in East London.
The new engine was released in 2000, to coincide with the launch of the Mk3 Ford Mondeo, the Duratorq ZSD-420 was initially available as a 2.0 litre (1998 cc) direct injection diesel. Producing 115 PS (113 hp/85 kW) and 280 Nm (207 ft·lbf) it was a vast improvement over the 1.8 Endura-D powering the Mk2 Mondeo. It featured a 16-valve cylinder head with twin chain driven camshafts and had a variable geometry turbocharger with overboost function.
In late 2001 the engine was fitted with Delphi common rail fuel injection and renamed the Duratorq TDCi (Turbo Diesel Common-rail injection), with the original unit being renamed the Duratorq TDDi (Turbo Diesel Direct injection). Although generally identical to the original engine, the addition of the common rail system meant power was increased to 130 PS (128 hp/95 kW), with torque rising to 330 Nm (244 ft·lbf). In 2002 the Duratorq TDDi was replaced by a detuned version of the Duratorq TDCi.
In 2005, Ford introduced the Duratorq ZSD-422, a 2.2 litre (2184 cc) turbodiesel for top-of-the-range versions of the Mondeo and Jaguar X-Type which produced 155 PS (153 hp/114 kW). This is unrelated to the PSA DW12 2.2 litre unit used in Peugeot, Citroën and Jaguar Land Rover applications.
The 2.4 litre (2,402 cc / 146.6 cu in) Duratorq ZSD-424 is a turbocharged and intercooled Diesel. Output is 75 PS (55 kW; 74 hp) to 137 PS (101 kW; 135 hp) and 185 N·m (136 lb·ft) to 285 N·m (210 lb·ft). It is used in Ford Transit, LDV Convoy, Lti TXII Taxi, and Land Rover Defender models (2007-2011).
