Jaguar Presents Ingenium Diesel Family

Jaguar Cars Ltd. says its all-new group of Ingenium 4-cylinder diesels are the brand's most efficient oil burners ever.

The modular 2.0-liter powerplants were designed in-house and will be built at the company's new $816 million factory in England's West Midlands at a rate of one every 36 seconds.

The diesels share their bore, stroke and cylinder capacity with gasoline Ingenium engines. All variants are turbocharged and will be fitted with automatic stop-start systems.

Two versions of the new diesel will debut in the compact Jaguar XE four-door coupe due in Europe next year. The $44,100 car, which will come to the U.S. in 2016, also will be available with two gasoline engines: a 2.0-liter turbocharged Ingenium four-banger and a supercharged 3.0-liter V-6.

One of the Ingenium diesels delivers 161 hp and 280 lb-ft of torque and is rated at 62 mpg and 99 g/km of carbon dioxide on the New European Driving Cycle, according to the company. The second engine makes 177 hp and 317 lb-ft of torque.

The all-aluminum engines are fitted with variable exhaust valve timing, low-pressure exhaust gas recirculation, selective catalytic reduction and twin balance shafts. Designers reduced engine noise with such features as an acoustic sump cover and decoupled injectors. Internal friction was cut 17%.

Other refinements include roller bearings on the cam and balance shafts, a computer-controlled variable oil and water pumps and electronically controlled piston cooling jets. Jaguar says internal friction was cut 17%.
