This is the AJ20D6, the 3.0L Ingenium inline-six turbo-diesel from Jaguar Land Rover that powers the diesel Defender, as the live page describes. It is engineered for efficiency, smooth operation, and off-road capability, mounted longitudinally with six cylinders and four valves each, high-pressure common-rail direct injection, and twin variable-geometry turbocharging for responsive power with minimal lag. A 48V mild-hybrid system assists acceleration and recovers energy, the engine pairs with an 8-speed automatic, and as a diesel it uses diesel fuel, AdBlue with SCR aftertreatment, a diesel particulate filter, and glow plugs. It makes about 296 hp and 650 Nm of low-end torque, the deep pulling power the Defender is known for.
High mileage, diesel-specific wear, and the demands of heavy-duty and off-road use are the usual reasons. A sound AJ20D6 restores the Defender's effortless low-RPM torque, towing and off-road capability, and refined, quiet cruising, with the engine inspected for compression before it ships. The mild-hybrid system works alongside the diesel rather than replacing it, so the swap is a diesel-engine job with the 48V hardware and aftertreatment accounted for.
