Renault has introduced a new direct injection turbocharged petrol engine co-developed by the Renault-Nissan-Mitsubishi Alliance and Daimler. Inaugurated on the Scenic and Grand Scenic lineup of MPVs, the new motor will be produced in Spain and progressively offered in the Renault range from 2018. This new engine offers significant improvement in driving pleasure, with better torque at low rpm plus greater and constant availability at high rpm, while reducing fuel consumption and CO2 emissions.
The new petrol engine block, coupled with manual and EDC dual-clutch automatic transmissions, is available in a variety of power ratings from 115hp to 160hp. It incorporates several recent Alliance-developed innovations, including Bore Spray Coating, a cylinder coating technology from the Nissan GT-R engine, which improves efficiency by reducing friction and optimising heat transfer.
Other technologies enhance driving enjoyment and reduce consumption and emissions. For instance, the pressure of the direct fuel injection has been raised by 250 bar and a specific combustion chamber design optimises the fuel/air mix. In addition, Dual Variable Timing Camshaft technology controls the intake and exhaust valves according to engine loads. The result is more torque at low revs and more torque available linearly at high revs, for a significant benefit in driving comfort with better mid-range response.
