Jaguar AJ-V8 engine

The AJ8 engine is manufactured in an all-new, dedicated Jaguar facility located within the Ford Bridgend Engine Plant in Bridgend, South Wales. The Jaguar "plant-within-a-plant" saved considerable investment costs by Jaguar. It is staffed by workers dedicated to Jaguar engine production and includes a linked flow-line of computer numerically controlled machines with automated loading and assembly. Component supply is on a "just-in-time" basis.[3][4][5][6]

The 4.0 L (3,996 cc) AJ26 engine was introduced in 1996. The number "26" comes from 12+6+8 (cylinders), because when the first ideas were sketched, a family of 6-, 8- and 12-cylinder engines was contemplated, although only the 8-cylinder version was produced. It has a square 86 mm (3.39 in) bore and stroke. It was updated in 1998 as the AJ27 with continuously variable valve timing. The AJ-V8 was updated again in 2000 as the AJ28. The naturally aspirated version produces 290 hp (216 kW; 294 PS) in the 2000–2002 XK8.

The 3.9 L (3,934 cc) AJ30/AJ35 variant is a unique displacement used only by Ford and Lincoln and is built in Ford's Lima, OH engine plant. Bore and stroke is 86 mm × 85 mm (3.39 in × 3.35 in). The AJ35 version introduced for the 2003 model year added variable valve timing of the intake camshafts and electronic throttle control. While the block, crankshaft, pistons, and connecting rods are all unique to this displacement, many other parts are shared with the AJ-V8 engines produced in the UK by Jaguar.

4.7L V8 in a 2012 Vantage

Aston Martin hand-assembles a special version of the AJ-V8 for the 2005 V8 Vantage known as AJ37. This unit displaced 4.3 L; 261.2 cu in (4,280 cc) and produces 380 bhp (283 kW; 385 PS) at 7,000 rpm and 409 N⋅m (302 lb⋅ft) at 5,000 rpm. This engine is unique to Aston Martin and features race-style dry-sump lubrication, which enables it to be mounted low to lower the centre of gravity. The firing order is the same as the other AJ-V8 engines although the cylinder numbering is different (AJ37 = 1-5-4-2-6-3-7-8 vs. AJ26 = 1-2-7-3-4-5-6-8). The engine is assembled by hand at the AM facility in Cologne, Germany, which also builds the V12 for the DB9 and Vanquish. The cylinder block, cylinder heads, crankshaft, connecting rods, pistons, camshafts, inlet and exhaust manifolds, lubrication system and engine management are all unique to the Aston Martin version.

In May 2008, Aston Martin released a new design that used pressed cylinder liners instead of cast-in liners. This allowed for thinner liners, and a higher capacity of 4.7 L (4,735 cc; 288.9 cu in) for the V8 Vantage. Called the AM14, power output increased to 420 bhp (313 kW; 426 PS) (an 11% increase on the previous 4.3-litre unit) and peak torque to 470 N⋅m (347 lb⋅ft) (a 15% increase). The Aston Martin V8 Vantage S features the same 4.7-litre V8 engine found in the base Vantage, but with improved intake airflow, new mufflers, and new programming that keeps the exhaust system's bypass valves open longer. The engine in the V8 Vantage S now develops 430 bhp (321 kW; 436 PS) at 7,300 rpm and torque of 490 N⋅m (361 lb⋅ft) at 5,000 rpm representing an increase of 10 bhp (7 kW; 10 PS) and 20 N⋅m (15 lb⋅ft) respectively. This engine is also used in the bespoke Aston Martin DB10 concept car for the 2015 James Bond film Spectre.

4.3, bore and stroke 89 mm × 86 mm (3.50 in × 3.39 in)

4.7, bore and stroke 91 mm × 91 mm (3.58 in × 3.58 in)

Applications:

• 2005–2017 Aston Martin V8 Vantage
• 2014–2015 Aston Martin DB10 (Concept car)

An all new direct injection 5.0 L engine family was introduced in 2009 (all new engine block).[8] Now featuring: spray-guided direct-injection, continuously variable intake and exhaust camshaft timing. The naturally aspirated engines also feature cam profile switching and variable track length inlet manifold. Supercharged engines make use of a sixth-generation TVS (Twin Vortices Series) supercharger. The 2010 model year engine conforms to EU5 and ULEV2 emissions regulations.[8]

The engine is controlled by Denso's Generation 1.6 Engine Management System. Later switching to Bosch for the F-Type and other mid-2010 models going forward.
