Renault reveals their new 1.6-litre twin-turbo diesel engine
The French carmaker has revealed its new twin-turbocharged diesel engine that it claims to better fuel consumption and reduce emissions by 25 percent when compared with the existing 2.0-litre turbo-diesel units.
This model is claimed to be the first 1.6-litre diesel engine to benefit from this twin-turbocharged technology, Renault’s Energy dCi 160 Twin Turbo has a capacity of 1598cc and is capable of producing 118kW of power and 380Nm of torque which mirrors the output of the 2.0 dCi engine currently employed by the Megane in overseas markets.
Renault says that the Euro 6b emission compliant unit delivers fuel consumption and CO2 emissions savings of 25 percent, which translates into a combined cycle figure of 4.4 litres per 100km in the Megane and average CO2 emissions of roughly 116 grams per kilometre.
According to the company the new engine will be employing a sequential turbocharging configuration made of one very low intertia turbocharger meant to help the engine reach 90 percent of its peak torgue from 1500rpm and then a second one takes over at faster engine speeds. The Energy dCi 160 Twin Turbo – according to Renault – will ensure a blend of low-end torque and high power at higher revs.
This technology has been influenced and developed with knowledge gained by Renault’s turbocharged 1.6-litre V6 Formula One 1 unit – new for the 2014 season. The carmaker also says that its new engine will also feature a transverse water flow system, U-section Uflex pistonr ings and a Diamond Like Carbon super-finishing of its cam followers.
The new engine is expected to make an appearance at next month’s Geneva motor show and will most likely be used in upcoming large and executive models, with the next-generation Megane and laguna successor also tipped to benefit.
