Having announced previously that a new line of high-efficiency Ingenium engines developed by Jaguar Land Rover for use in their upcoming vehicles will deliver a stellar mix of economy, flexibility, refinement and low emissions, the British automaker is now providing more specific tech details on the powertrains.
Engineered from the start to accommodate both transverse and longitudinal applications and be backed by either a manual or automatic transmission, Ingenium engines are modular in design, sharing a common bore, stroke, cylinder spacing and 500cc per cylinder displacement. Other shared features will be turbocharging, variable valve timing and start/stop circuitry. Although the initial gasoline and diesel duo will be 2.0-liter/4-cylinder exercises, the fundamental Ingenium architecture is fully scalable and can readily accommodate additional - or fewer - cylinders, larger/smaller displacements and any of several types of force-induction packages. It's also fully compatible with electrified hybrid systems. The first of these engines will bow early next year in the all-new Jaguar XE compact sedan.
"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.
Aluminum is key
In keeping with JLR's longstanding preference for using aluminum to help reduce mass, both varieties of Ingenium engines feature an aluminum block and head that sees them tip the scales up to 176 pounds below their current equivalents. Innovation extends deep inside as well, with efficiency-enhancing tricks like computer-controlled water and oil pumps that function only as needed, simplified cam drives, low-friction roller bearings, a dual-path cooling system that decreases warm-up times and electronically controlled piston cooling with jets that spray oil only as needed. This helps to bring engine temps to operating levels more quickly to reduce emissions.
"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," noted Ron Lee, Jaguar Land Rover Director of Powertrain Engineering. "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."
The first of JLR's new Ingenium engines to roll off the assembly line at the firm's new Wolverhampton plant will be a turbodiesel, with production slated to start in January.
