New Blue dCi diesel engines with SCR for the Dacia Duster

Dacia is introducing a new generation of its diesel engines on the Duster, which feature the latest systems for reducing polluting emissions. Renamed for the occasion “Blue dCi”, these new engines guarantee increased performance and optimized consumption at attractive prices.

The new “Blue dCi” engines feature the latest systems for reducing polluting emissions. Located in the exhaust line, the oxidation catalytic converter now includes Selective Catalytic Reduction technology (SCR). Operating with a urea-based solution (Adblue) this technology also eliminates more nitrogen dioxide emissions (NOx) and provides improved engine efficiency and performance.

In addition to the SCR system, the dCi 95 and 115 operate with a new air-water exchanger, a higher injection pressure (2,000 bars) and new gearbox ratios. These evolutions provide:

  • A 5 hp increase in power;

  • 30 N·m (240 N·m at 1750 rpm) of additional torque for the Blue dCi 95; and

  • Faster 0 to 100 km/h gaining more than 1 second on both versions.

Consumption and emissions of these two engines remain controlled at 115g of CO2 (NEDC BT) and 4.4L/100 km (53.4 mpg US) in the mixed cycle (data in the course of certification).

The Blue dCi will be rolled-out over the entire Dacia range in the next few weeks (including the Duster 4-wheel drive).



Properly cleaned diesel engines should be a benefit, + we'll see lots of these engines across the Renault / Nissan / Dachia range, so the engine matters a great deal.
A lot of people are not planning on giving up on diesel. The main problems now are political as the mood has turned well against diesel in cities in Europe.


It is about time... the new regulation comes in force by September 1.

It remains to be seen what the impact of the anti-diesel campaigns from Governments and NGOs will be on the long term. The last statistics in Sweden showed a halt in the decrease of diesel share but that could also be due to the end of current incentives and the introduction of a bonus-malus system shortly. If more manufacturers discontinue their supply of diesel cars, it is obvious that the share will go down further. This would effectively kill the most efficient heat engine ever invented (so far, nobody has had a better idea...). Moreover, this would happen when the cars have become as clean as gasoline cars regarding NOx and much cleaner regarding practically all other health effects. That would be the day of joy for all NGOs, who have had this on their agenda for a couple of decades. Perhaps it would have made some sense 25 years ago but not today. However, this is something they will never comprehend no matter how tight emission tight the limits are and no matter how good the margin to those limits will be (as already shown by some manufacturers).
