Pollution: Renault corrects its latest diesel

With this voluntary corrective, Renault diesel engines comply with Euro 6b in force should pollute less in real traffic conditions.
...
The refrain is now known. There is a gap between what the engine of your car uses when it operates in daily use and when placed under the strict conditions of the approval tests. And as the amount of polluting gases and carbon dioxide emitted in the atmosphere is directly proportional to the volume of fuel burned, the counters are panicking and minds of our councilors are heated.
As part of its voluntary approach studied in conjunction with the environmental NGO Transport & Environment, the PSA Group has measured this difference: its Peugeot 308 and Citroën C4 Grand Picasso with 1.6 BlueHDi Diesel engines of 120 hp consume up to
56% diesel in addition announced on trade catalogs. A shift observed in all manufacturers that the Community authorities would like to reduce.
In the turmoil raised by the scandal of deceptive software installed by the Volkswagen Group in some of its diesel engines, no manufacturer untouched by the investigations of environmental organizations. Italy's Fiat, Germany's Mercedes-Benz Renault as the French have all been blacklisted for their levels of nitrogen oxide (NOx) emissions deemed too distant formal values recorded during standardized testing approval.
Renault promises a painless measurement
The January 18 2016, Renault responded to the results of these tests by accelerating the recall of approximately 15.800 copies of the offending Renault Captur dCi. At the same time, the manufacturer considered questionable measured values, because of overly restrictive and not representative of the actual circulation in Europe. At the time, explained that Renault
"Engine control calibration error" can lead to a loss of efficiency of the famous NOx trap if disputed.On April 5, 2016, Renault is extending comparable measures to all Diesel vehicles in production. As of July 1, 2016, the operating range of the EGR exhaust gas recirculation system will be extended, "while maintaining the reliability and operating safety of the engine and the vehicle unchanged under all conditions of use. customer." In addition, the "frequency and efficiency of the purges of the NOx trap filter will be increased, with a more" robust "system, in order to better take into account the diversity of driving conditions."
Renault says
carefully that "these combined actions will lead on average, depending on the applications and the type of driving, to a halving of nitrogen oxides in the EGR extension zone." Either way, the driver shouldn't see any difference in terms of power, smoothness of operation.
or fuel consumption.
The new models incorporate 6b Diesel Euro Series these developments. Euro Diesel Vehicles 6b existing progressively integrate these developments into production in July 2016. From October 2016, customers already have a diesel Euro 6b vehicle will, in turn, apply for toll of these developments via a passage through the Network. An informative letter will received in the coming weeks. Information will also be available online on the Group's website:

Is the official date of entry into force of the Euro 6c for new types approved, by its application in September 2019 for all new vehicles. SCR technology is already in commercial vehicles Renault Trafic and Renault Master.
