Renault has begun production of the new Energy dCi 130 diesel engine (earlier post) at its Cléon site is starting production of the new flagship in Renault’s powertrain range, the Diesel Energy dCi 130. The Energy dCi 130 engine was developed by the Renault-Nissan Alliance, like the existing
2.0 dCi and V6 dCi units, and the future TCe 90 and TCe 115.
The new 1.6-liter Energy dCi 130 (R9M), the first in the “Energy” family, will gradually replace the old 1.9-liter dCi 130 unit (F9Q type), and offer fuel consumption and CO2 emissions that are 20% lower than for its predecessor, at about 4.5 L/100km (52.3 mpg US) or 117 gCO2/km.
The Energy dCi 130 delivers 130 hp (97 kW) and 320 N&iddot;m (236 lb-ft) of torque, and slots in between the dCi 110 range (also known as 1.5 dCi or K9K) and the dCi 150 to 180 hp (also known as 2.0 dCi or M9R).

This new engine is the first in the new generation of “Energy” combustion powertrains and features a number of CO2-reducing technologies not before applied at this level of the range. These include a stop&start system with regenerative braking and, as a European premiere, a new low pressure EGR loop.
Variable swirl control enables optimization of the air/fuel mix, and a variable displacement oil pump reduces power demands for its operation, resulting in fuel savings.

The R9M project started in 2006. The Powertrain Engineering department was asked to
develop a 130 hp low consumption, low carbon engine, with no trade-off in driveability.
The engineers decided to phase out the F9Q engine (1.9 dCi 130) from 2011. This
engine had reached its maximum upgrade potential with the transition to the Euro 5 standard.
Further optimization studies, to cut fuel consumption and emissions in particular, would be
more complex and require greater investment in the longer term than starting from scratch
with a new engine, Renault decided.
Of the 274 parts making up this new engine, 75% are new. This enabled the engineering team to incorporate advanced technologies right from the start. The Energy dCi 130 engine is also designed to be upgraded over time; it will be possible to add the new components necessary to make the engine compatible with the coming stringent Euro 6 standard.
The engine will be fitted on Renault and Nissan brands European mid-range vehicles (C segment). At Renault, it will be available primarily on Scénic and then Mégane. The new unit is expected to account for around 30% of the site’s total engine output from 2012.
