Jaguar AJ-V6 engine

Common card · No. 321218

The Jaguar AJ-V6 engine is a piston engine based on the Ford Duratec V6 engine. The Duratec V6 was originally designed by Porsche, under contract to Ford, using a proprietary Cosworth cylinder head design to meet Ford's design brief. One notable addition is the use of variable valve timing, a feature also shared with Mazda's version of the engine. It is available in 2.1 L (2,099 cc), 2.5 L (2,495 cc) and 3.0 L (2,967 cc) displacements. The AJ-V6 engine has an aluminium engine block. Its aluminium DOHC cylinder heads were designed by Jaguar Cars. Using sequential fuel injection, it has 4 valves per cylinder with VVT; fracture-split forged powder metal connecting rods; one-piece cast camshaft; and direct-acting mechanical bucket (DAMB) tappets — features that differentiate the AJ-V6 from the Ford and Mazda versions.
