Jaguar Land Rover (JLR) has revealed further technical details on its upcoming "Ingenium" I-4 engine family. The modular engine was designed completely in-house and will ultimately replace the current Ford and Peugeot-based gas and diesel I-4 engines. Like the current Ford EcoBoost-based turbocharged I-4 used in the Land Rover Freelander (LR2) and Range Rover Evoque, the base displacement for the Ingenium engine will be 2.0L but is designed to accommodate smaller and larger displacements. The engine is designed for both transverse and longitudinal applications, to work with both automatic and manual transmissions, and be adaptable to hybrid systems.
Naturally, fuel efficiency was one of the primary design targets with the new engine, and to that end, the Ingenium family features roller bearings for the camshafts and balance shafts, variable-flow water and oil pumps, a split-circuit cooling system allowing for faster warm-up and cabin-heater function, and electronically controlled piston oil cooling jets that function on an as-needed basis.
JLR is claiming a weight savings of as much as 176 pounds compared to predecessor engines. All versions of the Ingenium -- gas or diesel -- will be turbocharged. The first models to get the new engine are expected to be the Land Rover Discovery Sport and the forthcoming Jaguar XE compact sports sedan. The Ingenium engines will be built at JLR's Wolverhampton, England, engine plant.
