PSA Peugeot-Citroen has had its diesel engines tested by the French Ministry of Ecology, and the results are aligned with homologated data.
The tests were done by a special technical committee started by the French Ministry of Ecology, Sustainable Development and Energy to ensure that the country’s main carmakers comply with regulations and with their homologated data.

In Peugeot-Citroen’s case, the committee probed the diesel engines of the Peugeot 208 and 508. These models are fitted with BlueHDi diesel units that have Selective Catalytic Reduction Technology. PSA Peugeot-Citroen implemented the SCR upstream of the particulate filter to ensure elimination of up to 90% of the nitrogen oxides released by this engine category.

The people of PSA Peugeot-Citroen claim their SCR fitment brings nitrogen oxide emissions to levels near to those of gasoline engines. However, diesel engines eliminate 15% less CO2 emissions than equivalent gasoline power plants, all while having a 20 percent better fuel efficiency.

The French company first introduced its BlueHDi technology in late 2013, two years before the Euro 6 standard became mandatory for new cars sold in Europe. The PSA Peugeot-Citroen corporation invested several hundred million euros in the development of improved SCR technology. Their investment was safeguarded with around one hundred patents.

The work of PSA Peugeot-Citroen engineers is far from over, though, as the company is planning a new engine range meant to comply with the next emission standards. We are talking about the Euro 6.2 standard, intended to become mandatory for all cars made and sold after September 2017.

Until then, PSA Peugeot-Citroen waits serenely for the next wave of test results. The manufacturer prides itself on the fact that its engines were perfectly in line with the law and homologated results, as its main French competitor, Renault, was also probed by Government authorities and the results were not as good, apparently.

Renault’s diesel engines complied with the law, but had rather high emissions on specific models, and company officials were asked to explain why that happened and how would they fix it.
