Jaguar Land Rover’s New Engine Offers Diesel And Hybrid Possibilities

Jaguar Land Rover is launching a new family of engines, one that will be made in diesel and gasoline versions, as well as eventually linked to a hybrid system.

Known as Ingenium, the new family of diesel and gasoline engines designed, engineered and manufactured by Jaguar Land Rover (JLR) are said by the company to deliver exceptional levels of torque, horsepower and refinement while offering reduced emissions and improved fuel consumption.

JLR said the targets defined for this new engine family include:

  • Configurable and flexible architecture that enables seamless installation in a range of new Jaguar and Land Rover vehicles
  • Scalable to create smaller or larger displacement variants in the future
  • Ability to accommodate a range of powertrain layouts including rear-, all- and four-wheel drive
  • Engineered to support manual and automatic transmissions as well as electrified hybrid drive systems
  • Easily accepting of new advances in engine technologies as they become available

For both diesel and gasoline versions, the engine is based on a strong and compact aluminum block, explained JLR. Sharing the same bore, stroke, cylinder spacing and 500cc cylinder capacity, these blocks allow flexibility for future development of smaller or larger engine options. This modular design also enables both gasoline and diesel variants to share common internal components and calibration strategies. This reduced complexity simplifies manufacturing and raises quality while allowing for quick reaction to changes in global demand.

“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,” said Dr. Wolfgang Ziebart, Jaguar Land Rover Group Engineering Director. “Engineering and manufacturing our own engines improves our ability to react to changes in demand and improves our ability to react to changes in legislation and competitive technologies in the future. We believe that with the range of technologies we are investing in, Jaguar Land Rover can absolutely satisfy the often conflicting requirements of delivering engaging high-performance luxury vehicles that reduce our carbon footprint in the long-term.”

All diesel and gasoline Ingenium versions will be equipped with turbochargers that improve performance, particularly at low speeds, and help reduce fuel consumption and emissions. JLR added other features include high-pressure central direct fuel injection, variable valve timing and start-stop technology.

The Ingenium engine is currently undergoing a series of integrity and durability tests, which include more than 72,000 hours of dynamometer testing and two million miles of real-world testing, to ensure these engines will meet and exceed all customer expectations, said JLR. The first Ingenium engine to go into production, a 2.0-litre diesel will be known as AJ200D.

Per the company, the Ingenium engine family features six key technologies that combine to reduce friction, increase refinement and improve performance. They include:

  • Roller bearings on cam and balancer shafts, instead of machined bearing surfaces.
  • Computer-controlled variable oil pumps that save energy by delivering the optimum amount of oil at all speeds, engine loads and temperatures.
  • Computer-controlled variable water pumps that adjust the amount of coolant flow, based on temperature, speed and driving conditions. The split circuit (two path) cooling system offers the benefit of lowered emissions by enabling fast warm ups, and also quick cabin heat on cold days.
  • Simplified cam drive system designed for modular applications.
  • Crankshafts that are offset from the center of the block.
  • Electronically controlled piston cooling jets to improve efficiency in the oil pump circuit. These jets are switched off when piston cooling is not needed. They also enable the engine to quickly reach its operating temperature, helping to reduce emissions.

Using the company’s aluminum chassis expertise, the company managed to reduce the weight of this new engine family. Despite adding features and increasing power output, Ingenium engines weigh as much as 176 lbs. less than today’s equivalent engines.

“Ingenium fulfills our commitment to offer our global customers some of the most advanced powertrains available in some of the lightest vehicles in the premium SUV and performance car segments,” said Ron Lee, Jaguar Land Rover Director of Powertrain Engineering. “Being configurable and flexible are the two key strands of Ingenium’s DNA because we have future-proofed our new engines from the outset. Ingenium will be able to accept new advances in fuel, turbocharging, emissions, performance and electrification technologies when they are ready and accessible to be deployed. We were able to design Ingenium in this way because we had the rare opportunity to start the project with a clean sheet of paper. We weren’t locked into any of the usual restrictions that force engineering compromises because we had no existing production machinery that would dictate design parameters, no carryover engine architectures to utilize and no existing factory to modify.”
