Jaguar-Land Rover’s new line of engines – Ingenium – has débuted in the Land Rover Discovery Sport, Range Rover Evoque, as well as the new Jag XE.
The Ingenium line marks the arrival of the company’s all-aluminium modular engine architecture, which will provide for diesel and petrol propulsion units. The first of the lot are the new 2.0-litre four-cylinder turbo-diesel units, available in two states of tune: 163 PS and 380 Nm, and 180 PS and 430 Nm.
All Ingenium engines have been developed from scratch by Jaguar engineers and are based around a deep-skirt aluminium cylinder block featuring thin-wall, press-fit cast iron liners: offering the best balance of weight, surface finish, and robustness. The split-cooling system, mapped thermostat, and fully-variable mechanical water pump enable standing water in the block while coolant circulates through the cross-flow channels in the head. Thus, the engine warms up quicker, while friction is reduced, as is fuel consumption.
Fuel is fed to the combustion chambers by an 1,800-bar solenoid common-rail direct injection system. The highlights of this new system are lower noise, higher efficiency and excellent mixture formation. Variable valve timing is now a part of this diesel line-up. The Ingenium engines benefit from a cam phaser on the exhaust side. Variable exhaust valve timing enables more rapid catalyst heating, thus minimising harmful emissions during the critical warm-up phase.
Moreover, parasitic losses have been cut further. The electronically-controlled oil-pump matches its flow rate according to engine speed, load and temperature. The switchable piston-cooling jets kick in only when required.
The result? Ingenium diesel engines are have a rapid torque build-up from very low engine speeds, enabled by highly efficient variable geometry turbochargers. Maximum torque is maintained over a much wider rev-range, allowing for instantaneous response and strong acceleration whenever needed.
The 2016 Range Rover Evoque in Europe has gone on sale with the new Ingenium units, and Jaguar have the new XE ready for deliveries. For now, the petrol motors are the 2.0-litre turbocharged direct-injection Si4 units seen earlier, but are now offered in two states of tune: 200 PS and 280 Nm, and 240 PS and 340 Nm. The engines are paired with either a six-speed manual or the ZF 8HP eight-speed automatic transmission in the XE, whereas the Discovery Sport and Range Rover Evoque uses the ZF 9HP nine-speed automatic.
The new Ingenium petrol units should be revealed in the model year to come. We can also expect six- and maybe even three-cylinder configurations in the future. The new Land Rover Range Rover Evoque, Discovery Sport (in 5 and 5+2 seater configuration) and the Jaguar XE will all make their way to India very soon.
