Ingenium Engine Family 2014 – Present

Ingenium Production Line

In September 2014, Jaguar Land Rover announced the Ingenium family, a range of modular engines produced in both petrol and diesel variants to power the new Jaguar XE and future models from Jaguar Land Rover.  Ingenium uses a modular architecture making it possible to be produced in 3, 4, 5, and 6 cylinder versions (built around individual 500cc cylinders), and as hybrid variants, depending on demand and requirements.  From late 2015, Ingenium replaced the engines sourced from Ford. The engine range is produced at the new £500 million, 100,000m2 Engine Manufacturing Centre at Wolverhampton in the West Midlands in the UK.

Ingenium’s design is configurable and flexible for longitudinal and lateral architectures and for front, rear, and all-wheel drive, together with auto and manual transmissions.    Depending on configuration, engines have either a single twin-scroll turbocharger, or two twin-scroll turbochargers, with ceramic ball bearings.  Valve train design follows the traditional Jaguar approach of chain driven double overhead camshafts (DOHC). Particular emphasis has been placed on achieving exceptionally low internal friction, which is described as being 17% less than its 2.2 litre diesel predecessor.   Computer-controlled variable oil and water pumps, a split circuit cooling system enable fast warm ups. While a simplified cam drive system, crankshafts that are offset from the centre of the block and electronically controlled piston cooling jets all help to improve efficiency in the oil pumping circuit.

Starting from a clean sheet meant that Jaguar’s powertrain engineers could make the Ingenium engines as light and efficient as possible, and deliver the blend of power, torque and smoothness customers expect. These state-of-the-art engines were proven over 2 million miles of real-world testing.

Ingenium Diesel Engines

Ingenium Diesel

The new generation of Ingenium diesel engines are wholly designed and manufactured by Jaguar Land Rover. No opportunity has been missed in ensuring their design is right on the cutting edge of technical advancement making them the the most efficient Jaguar diesel engines ever built.

The engine blocks are cast from aluminium alloy, with steel liners, producing stiff cylinder blocks with twin balancer shafts to ensure inherently low levels of vibration. Details such as the acoustic sump cover, decoupled injectors, and 0.5mm ovality on the injection pump drive sprocket contribute to the Ingenium’s exceptional quietness. The cam and balancer shafts have roller bearings instead of machined-in bearing surfaces helping to produce a very low friction engine.

Ingenium Diesel Cutaway

The AJ200D 2.0-litre Ingenium diesel was initially offered in two power outputs. The first, rated at 163PS / 380Nm, delivers benchmark efficiency figures of 75 mpg and 99 g/km CO2 without any compromise to launch performance or mid-range acceleration. The 180PS / 430Nm variant has one of the highest torque outputs in the class.  Further versions have since been launched offering 150PS / 380Nm and 240 PS / 500Nm.

Ingenium diesels met Euro 6 specifications making them as clean as they are efficient. Variable exhaust valve timing shortens the catalyst light-off phase and also improves diesel particulate filter (DPF) regeneration. The cooled low-pressure exhaust gas recirculation (EGR) system reduces combustion chamber temperatures, inhibiting NOx formation. Selective catalytic reduction (SCR) technology, including the injection of AdBlue into the exhaust system, cuts NOx emissions to very low levels and the new XE has been engineered to meet the most stringent global regulations.

Ingenium Petrol Engines

Ingenium Petrol Cutaway

Petrol versions were launched in 2016, using the same architecture, initially in 2 versions based on direct injection 1,999 cc, four cylinder, turbo charged configurations:  200PS / 320Nm and 250PS / 365Nm with a single turbo charger.

In 2017 a twin turbo-charged 300PS / 400Nm engine with an electro-hydraulic valvetrain was launched.  Jaguar Land Rover licensed the MultiAir / UniAir electrohydraulic variable valve lift system from Schaeffler Group, which Schaeffler in turn licensed from Fiat Chrysler Automobiles in 2001.  The system, developed by Fiat Powertrain Technologies, is a hydraulically-actuated variable valve timing (VVT) technology enabling “cylinder by cylinder, stroke by stroke” control of intake air directly via a gasoline engine’s inlet valves.

The new four-cylinder engine, badged P300, benefits from the latest Jaguar Land Rover engine technology, including twin-scroll turbos with ceramic ball bearings to reduce friction and a high flow compressor wheel for enhanced performance.

Producing 400Nm of torque it gives exceptional acceleration, enough to power the, World Car of the Year-winning, F-PACE from 0-100km/h in 6.0 seconds (0-60mph in 5.7 seconds) but still return fuel economy of 37mpg (7.7 l/100km).

In the Jaguar XF saloon the P300 engine delivers 0-100km/h in 5.8 seconds (0-60mph in 5.5 seconds) in all-wheel-drive form.  With CO2 emissions of 163g/km and fuel economy of 40mpg (7.2 l/100km), it delivers traditional Jaguar performance allied to impressive efficiency.

For the XE saloon, the P300 engine delivers even more impressive figures. The 0-100km/h sprint takes only 5.5 seconds (0-60mph in 5.2 seconds) for the all-wheel-drive model, while fuel economy of 41.5mpg (6.9 l/100km) and CO2 emissions of 157g/km ensure its strong eco credentials remain intact.
