Ingenium is a new family of aluminum powerplants that will replace the aging lineup of petrol and diesel mills in the near future. Although Jaguar still keeps its lips tightly shut about all there is to know about the new motors, the British marque has made an announcement about the 2-liter Ingenium diesel.It's a four-cylinder mill dubbed as the most efficient diesel ever produced by Jaguar. To be offered at launch next to the XE S' 3-liter supercharged V6, the 2-liter Ingenium diesel will come in two outputs: 163 PS (160 hp) / 380 Nm (280 lb-ft) and one that develops 180 PS (177 hp) / 430 Nm (317 lb-ft).Jaguar says the lesser powered variant can deliver up to 75 UK mpg (62.4 US mpg / 3.76 l per 100 km) and produces 99 grams of CO2 per kilometer. But the Brits "forgot" to mention if this is doable on the motorway, in the city or if it's the combined figure. Nevertheless, Jaguar promised to release more information about these oil burners at the Paris Motor Show next week. But 'til then, there's some details we deem necessary to mention about this new Jaguar XE motor.Both variants of the 2-liter Ingenium diesel employ turbocharging and other technologies for improved efficiency, adequate torque and stuff like that. Thus, both mills are compliant to the Euro 6 standard. In addition to that, the low friction, all-aluminum units use stiff cylinder blocks and twin balancer shafts to ensure inherently low levels of vibration. An acoustic sump cover, decoupled injectors and 0.5 mm ovality on the injection pump drive sprocket also contribute to the Ingenium engine's smoothness in operation.Jaguar also tells that variable exhaust valve timing shortens the catalyst light-off phase and improves diesel particulate filter regeneration. The cooled low-pressure exhaust gas recirculation () system is there to reduce combustion chamber temperatures, inhibiting NOx formation. Furthermore, selective catalytic reduction (SCR) technology cuts NOx emissions to very low levels, which is nice for those Jaguar owners with a passion for the environment. If such a type of Jaguar owner exists, that is.
