JLR Reveals Details About Jaguar XE's Engine

Jaguar Land Rover officially announced its new family of engines - Ingenium - when it unveiled the 2.0-litre version in the Jaguar XE concept at the 2014 Geneva Motor Show. However, it had refrained from giving out much detail about it back then. Up till know, all we knew was that these new turbocharged engines could be configured to use petrol or diesel. Also, that they could be positioned longitudinally or transversely. That was all we knew for months, and we've held our breath since then. Turns out, the waiting is kind of over since the company has finally let out some more information about the Ingenium family.

The new family of premium diesel and petrol engines delivers class-leading performance and refinement while reducing emissions and fuel consumption. JLR developed its own new family of advanced technology, low-friction, high-performance petrol and diesel engines to meet the growing demand for lower fuel consumption and cost of ownership, without compromising performance and the driver experience.

The company's engineers have based Ingenium's foundation on extremely strong and compact aluminium blocks for both, diesel and petrol versions. These lightweight blocks share the same bore, stroke, cylinder spacing and 500cc cylinder capacity. This endows Ingenium with configurability and flexibility around which, smaller or larger engines can be developed quickly and efficiently.

All diesel and petrol Ingenium engines will be equipped with state-of-the-art turbochargers that improve performance, particularly at low speeds, and reduce fuel consumption and CO2 emissions. Also, its modular design allows both, petrol and diesel, engines to share several internal components and calibration strategies. This further helps reduce complexity, raises quality and simplifies manufacturing, which in turn, will allow JLR to adapt more quickly to changing global demands.

Dr. Wolfgang Ziebart, Jaguar Land Rover Group Engineering Director, said, "Customers around the world are increasingly demanding cleaner-running, more efficient vehicles that maintain or even enhance the performance attributes expected of a rugged all-terrain vehicle or a high performance car. Our Ingenium engines deliver this to a new level."

Ingenium engines feature the following key technologies that come together to reduce friction, add refinement and improve performance:

1. Roller bearings on cam and balancer shafts, instead of machined-in bearing surfaces.

2. Computer-controlled variable oil pumps that save energy by delivering the optimum amount of oil at all speeds, engine loads and temperatures.

3. Computer-controlled variable water pumps that adjust the amount of coolant flowing through the engine, based on temperature, speed and driving conditions. The split or twin circuit cooling system offers the twin benefits of lowering CO2 emissions by enabling fast warm ups, and providing quick cabin heat on cold days.

4. Simplified cam drive system designed for modular application.

5. Crankshafts that are offset from the centre of the block.

6. Electronically controlled piston cooling jets to improve efficiency in the oil pumping circuit. Jets are switched off when piston cooling is not needed. They also enable the engine to reach its optimum operating temperature faster, further helping to reduce CO2 emissions.
