The '''AJD''' is a family of [[V6 engine|V6]] and [[V8 engine|V8]] [[turbodiesel]] engines with a clean-sheet architecture and [[variable valve timing]] developed by [[Ford of Europe]] for its then-subsidiaries [[Jaguar Cars|Jaguar]] and [[Land Rover]], as well as for its partner [[PSA Group]] working under the Gemini joint development and production agreement. It is called the '''AJD-V6''' in the Jaguar and Land Rover vehicles and the '''DT17/DT20''' by [[Citroën]] and [[Peugeot]]. The engines share the same bore/stroke ratio, with the V6 version displacing {{convert|2720|cc|L|1|order=flip|abbr=on}} and the V8 version displacing {{convert|3630|cc|L|1|order=flip|abbr=on}}. The V6 and the V8 were launched in 2004 and 2006 respectively. The V6 engine meets the Euro IV emissions standards. A '''DT20''' {{convert|2993|cc|L|1|order=flip|abbr=on}} was added in 2009 and is based on the '''DT17''' {{convert|2720|cc|L|1|order=flip|abbr=on}}. The V6 is used across many vehicles, from the [[Citroën C5]] and [[Citroën C6|C6]], to the [[Land Rover Discovery]], [[Range Rover]], multiple cars in the Jaguar range, and also the [[Ford Territory (Australia)|Ford Territory]] and next gen [[Ford Ranger (T6)#2|Ford Ranger]].
== Common construction ==
The engine family utilises [[DOHC|twin overhead camshafts]] and [[multi-valve]]s, single or [[twin-turbo]]chargers with an air-to-air [[intercooler]], and innovative [[compacted graphite iron]] (CGI) block construction that leads to a low weight of {{convert|202|kg|lb|abbr=on}} dry. Fuel supply is high-pressure [[common rail]] [[fuel injection#Direct injection systems|direct injection]].
==Lion V6==
[[File:Jaguar XJ (X350) 2.7 liter V6 turbo diesel engine.jpg|thumb|AJD-V6 engine in a 2006 Jaguar XJ]]
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]]<ref>{{cite journal|first1=Wilson Luiz |last1=Guesser|first2=Pedro Ventrela |last2=Duran|first3=Walmor |last3=Krause|url=http://www.tupy.com.br/downloads/guesser/compacted_graphite_iron_for_diesel.pdf |title=Compacted Graphite Iron for Diesel Engine Cylinder Blocks|journal=Congrès le diesel|publisher=Ecole centrale Lyon | date=12–13 May 2004}}</ref> – is a member of the [[Ford Duratorq engine|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 in automobiles|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&nbsp;rpm, the larger turbocharger is also used to pressurize the intake.
Jaguar tested fitting the engine to its [[Jaguar XK|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.

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&nbsp;L variant is built in Ford's [[Chihuahua Engine]] plant in [[Mexico]].
Much speculation in the United States has focused on this engine as a possible Diesel entrant in the [[Ford F-Series|F-150]] pickup truck and [[Ford Expedition|Expedition]] SUV.<ref>{{cite web|first=Richard|last=Truett|date=31 July 2006|url=http://autoweek.com/apps/pbcs.dll/article?AID=/20060802/FREE/60731013/1024/LATESTNEWS|title=Powertrain Plans|work=[[AutoWeek]]| accessdate = 2 August 2006}}</ref> It was announced that the new F-150 engine was to be based on this engine and enlarged to 4.4&nbsp;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&nbsp;L Lion V6 modified for US truck use, utilising a single turbocharger.
