Ingenium, a new family of premium diesel and gasoline engines designed, engineered and manufactured by Jaguar Land Rover, will deliver exceptional levels of torque, horsepower and refinement while offering reduced emissions and improved fuel consumption.
For both diesel and gasoline versions, the engine is based on a strong and compact aluminum block. 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.
All diesel and gasoline Ingenium variants will be equipped with turbochargers that improve performance, particularly at low speeds, and help reduce fuel consumption and emissions. Additional features include high-pressure central direct fuel injection, variable valve timing and start-stop technology.
The Ingenium engine is undergoing a series of integrity and durability tests, which include more than 72,000 hours of dynomometer testing and two million miles of real-world testing, to ensure these engines will meet and exceed all customer expectations. The first Ingenium engine to go into production, a 2.0-litre diesel will be known as AJ200D.
Technology
The Ingenium engine features innovations that will deliver outstanding low-end torque, effortless acceleration and excellent emissions performance with low fuel consumption. To accomplish this, a strong focus has been placed on reducing internal friction of powertrain components.
Ingenium engines feature 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.
Key Role in Vehicle Weight Reduction
Jaguar Land Rover is a specialist in the production of aluminum-bodied vehicles. The introduction of the Ingenium engine unites the company’s aluminum chassis expertise with powertrains specifically designed and calibrated to complement reduced weight vehicles. Despite adding features and increasing power output, Ingenium engines weigh as much as 176 lbs. (80 kg) less than today’s equivalent engines.
