Renault New 1.6-litre energy dCi 160 Twin Turbo engine

Renault announces the first new 1.6- litre energy dCi 160 twin-turbocharging engine, which gain 25% of fuel-consumption. The 1,598cc engine will deliver 160hp of power and 380Nm of torque, which catapults it into the domain of 2-litre engines in terms of performance.

Twin-turbocharging:

The ‘Twin Turbo’ technology for this diesel engine ensures a blend of low-end torque and high power at higher revs, the obvious benefit of which being enhanced driving enjoyment.

The system comprises two sequential turbo-compressors:

  • The first is a very low inertia turbo which provides high low-end torque for crisp pull-away and mid-range acceleration. To guarantee impressive pick-up response at low revs and incisive acceleration, 90% of peak torque is available from 1,500rpm.
  • The second turbo assumes the reins at the higher-end and produces high power (100hp per litre) at faster engine speeds to ensure smooth, linear, dependable acceleration right the way up to maximum revs.

A hi-tech unit boasting technology borne out of Renault’s F1 expertise

This expertise in the field of sophisticated turbochargers is not the only link between the 1.6-litre Renault Energy F1 Power Unit and the Energy dCi 160 Twin Turbo block which takes advantage of a number of technologies borne out of Renault’s know how in F1, notably in terms of cooling and friction reduction:

  • The transverse water flow system permits faster and more efficient cooling of the combustion chamber.
  • ‘U’-sectionU-Flex piston rings adapt to changes in the form of the cylinder walls resulting from fluctuations in temperature and pressure to yield the optimum compromise between efficiency and friction.
  • DLC (Diamond Like Carbon) super-finishing of the cam followers also reduces friction.

The fuel injection system of the Energy dCi 160 Twin Turbo operates at a pressure of 1,800 bar to function with the twin turbocharger. It complies with Euro 6b emissions legislation and incorporates a NOx Trap and particulate filter regeneration system.

By dint of its efficiency, this engine is comfortably capable of powering larger vehicles, and will notably be available for Renault’s forthcoming D- and E-segment models.
