JAGUAR/LAND ROVER 4.4 AJ31

The Jaguar AJ-8 is a compact DOHC V8 piston engine used in many Jaguar vehicles. It was the fourth new engine type in the history of the company. In 1997 it replaced both designs previously available on Jaguar cars: the straight-6 Jaguar AJ6 engine (or rather its AJ16 variant), and the Jaguar V12 engine. It remained the only engine type available on Jaguar until 1999 with the launch of the S-Type, when the Jaguar AJ-V6 engine was added to the list. The AJ-V8 is available in displacements ranging from 3.2 L to 5.0 L, and a supercharged version is also produced. Ford Motor Company used this small V8 in other products as well, including the Lincoln LS the 2002-2005 Ford Thunderbird as well as in several Land Rovers and the Aston Martin V8 Vantage. The AJ-V8 was designed to use Nikasil-coated cylinders rather than the more-common iron cylinder liners. However, like the BMW M60, high-sulphur fuel reacted with the Nikasil liners and caused engine failures. Jaguar replaced affected engines, and has used conventional cast-iron linings ever since. The engine originally used a two-state Variable Valve Timing system to switch the intake cam timing by 30°. Newer variants use a more sophisticated system which can vary intake timing incrementally up to 48°. The Lincoln version was made in the United States. Other engine features include fracture-split forged powder metal connecting rods, a special one-piece cast camshaft, and reinforced plastic intake manifold. The 4.4 L (4,394 cc (268.1 cu in)) AJ41 version features an 88.0 mm (3.46 in) bore and a 90.3 mm (3.56 in) stroke. This engine also replaced the BMW M62 engine used in 2003-2005 Range Rover models.
