Renault has unveiled a new twin-turbocharged 1.6 litre twin-turbo diesel, which the French carmaker claims is a first for a diesel engine of its size.
The twin-turbo design is aimed at maximising low-end torque, while also boosting power at higher revs, with Renault saying the new engine “feels like a 2.0 litre”.
Besides the two turbochargers, the new ‘Energy dCi 160 Twin Turbo’ power plant also comes with a 25 percent improvement in fuel consumption.
Renault claims its new Formula 1 Power Unit for the 2014 season has played a significant part in the twin-turbo diesel’s development, with both engines sharing a 1.6 litre capacity.
Friction-reducing and cooling technology, ‘U-Flex’ piston rings and Diamond Like Carbon (DLC) finishing of the camshaft followers are all borrowed from the new F1 Power Unit.
Put it all together, and the Energy dCi 160 Twin Turbo produces 118kW (or 160 HP – 100 HP per litre) and 380Nm, with 90 percent of torque available from 1500 RPM.
The fuel injection system for the new diesel engine operates with 1800 bar of pressure to function with the twin turbochargers, and the unit complies with Euro 6b emissions legislation.
Renault says the new 1.6 litre Energy dCi 160 Twin Turbo is capable of powering larger vehicles. In Australia, that means we may see the new engine available in the Laguna and Fluence at the very least, at some stage in the future.
