Too much NOx
Of the tens of millions of passenger cars with a Euro 5 or Euro 6 diesel engine sold between 2009 and 2019, almost 80 percent emit too much nitrogen oxides (NOx), according to new research. According to researchers from The International Council on Clean Transportation (ICCT), this probably points to the presence of ‘cheating software’.
At the end of 2020, the Court of Justice of the European Union (CJEU) ruled that car manufacturers so-called defeat devices – software and/or hardware that can affect an engine’s emissions – are only allowed to operate in cars to avoid ‘risk of imminent danger if the car is driven.’ According to the Court of Justice, clever systems reduce emissions from a diesel engine to prevent clogging or to extend the life of the power source. Non-profit organization International Council on Clean Transportation (ICCT) has compared the emission data of different makes and models with different engine families from different data sets. For example, it has compared emission data established by government agencies in laboratories as well as in practice, emission data established in practice by independent organizations and data from a database with emission data determined remotely. With striking conclusions.
According to ICCT, it has detected “suspicious” NOx emissions in the emission data of 77 percent of Euro 5 and Euro 6 diesels. According to ICCT, this indicates that “[…] probably defeat devices The data determined by government agencies would show “extreme” NOx emissions in 42 percent of the diesels included in the study, which according to the organization “almost certainly” indicates active cheating software and hardware. ICCT says that at least 66 models contain systems that, according to the recent ruling of the CJEU, unlawfully reduce emissions the ICCT study we come across diesels from Renault, Volkswagen, Ford, Peugeot, Ctroën, Fiat, Alfa Romeo, BMW, Mazda, Mitsubishi, Volvo, Mercedes-Benz, Opel, Audi, Nissan and Skoda.
