Ford AJD-V6/PSA DT17

Common construction

The engine family utilises twin overhead camshafts and multi-valves, single or twin-turbochargers with an air-to-air intercooler, and innovative compacted graphite iron (CGI) block construction that leads to a low weight of 202 kg dry. Fuel supply is high-pressure common rail direct injection.

Lion V6

To improve the engine's low-speed torque range for off-roading and towing applications, the Land Rover variant utilised a large capacity single-turbocharger, rather than use the twin-turbo design; in addition the engine is fitted with a large engine driven cooling fan to support low speed, high load driving as may be encountered in desert conditions. Furthermore, the Land Rover variant of the Lion V6 includes a deeper, high capacity sump with improved baffles to maintain oil pressure at off-roading extreme angles and multi-layered seals to keep dust, mud and water at bay and different transmission bell housing bolt pattern. The Lion V6 – constructed from compacted graphite iron – is a member of the Ford Duratorq family and is produced at Ford's Dagenham engine plant; 35,000 engines were produced from April to December 2004.

The 3.0-litre design, known as the Gen III, superseded the 2.7-litre, and uses turbochargers on a series-sequential system and has an uprated common rail injection system incorporating fuel injectors with piezo crystals fitted nearer to the tip to reduce engine noise and a metering mode to reduce oversupplying fuel, decreasing fuel consumption and unused fuel temperature over the 2.7-litre model. The sequential turbocharger system utilizes the smaller of the two turbos when the engine is running at low revolutions; once the engine has reached 2,800 rpm, the larger turbocharger is also used to pressurize the intake.

Jaguar tested fitting the engine to its XK model but didn't carry the project over to production.

The 3.0-litre variants used by Land Rover feature the 2.7-litre's off-roading adaptations plus calibration of the engine's electronics to allow the use of low-quality fuels.

Lion V8

Built at Ford's Dagenham engine plant in Essex, the 3.6-litre V8 twin-turbo diesel engine began production in April 2006. The 4.4 L variant is built in Ford's Chihuahua Engine plant in Mexico.

Much speculation in the United States was focused on this engine as a possible Diesel entrant in the F-150 pickup truck and Expedition SUV. It was announced that the new F-150 engine was to be based on this engine and enlarged to 4.4 L, but that program was later cancelled. The Cleveland Engine plant recently began small-scale production of the exotic compacted graphite iron (CGI) used in the block's construction, leading many to expect production of the engine there. Ultimately, Ford went with the 3.0 L Lion V6 modified for US truck use, utilising a single turbocharger.
