More details emerge from the investigation of the Environmental Protection Agency (EPA) against Volkswagen by using software installed on their diesel vehicles sold in the US between 2008 and 2015 to “cheat” tests of greenhouse gas emissions and emit 10 to 40 times above the permitted level pollutants.
Since last Friday, 9/18, when the research information was disclosed, the company admitted to practice; its CEO, Martin Winterkorn, resigned from office; and found that 482,000 cars affected in the US turned into nearly 11 million VW vehicles around the world and that the company should face fines of at least $ 18 billion.
In this Friday, 9/25, the board of Volkswagen is meeting to appoint a new CEO, who will possibly be Matthias Müller, executive 62 years who now leads the Porsche company is also part of the VW group
Details on how the software installed by the automaker deceived the pollutant emission test. – in case the so-called nitrogen oxides (NOx), gases highly toxic generated by burning fossil fuels – are included in the letter from the EPA for VW dated September 18
According to the EPA, “the position of the steering wheel, the vehicle speed, the time that the. motor was turned on and barometric pressure – all very specific indicators of an emissions test – functioned as an activation trigger for the ‘cheating device.’ ” Essentially the electronic control module of the vehicle (ECM) was changed to work in “clean” mode during the test run period.
“Miracle” technology
Kirk Wennerstrom, director of marketing at Greenwich Concours d’Elegance, a company specializing in ‘vintage’ cars in the town of Greenwich, Connecticut (USA), explains that the EPA tests involving the simulation of a number of different speeds, sudden stops and starts and simple. “What VW did was more or less as an average student hire a nerd to pass him and gabaritar the entrance exam.”
To meet the exhaust emission specifications, car manufacturers diesel injecting a special fluid called AdBlue into the exhaust stream that catalyzes the NOx fumes. This feature reduces indeed the pollutant emissions to the level required but adds weight and cost to cars and compel their owners to bear more expenses of maintenance as from time to time the fluid must be reset.
“The VW was the market say he had found a way to meet the standards without AdBlue, “says Wennerstrom. “Everyone was amazed to innovation and I’m sure that many manufacturers have tried a reverse engineering in VW engines to find out how she was doing.”
left for BMW
In the light of the VW emissions scandal, the BMW’s shares also fell on Thursday after the German magazine Auto Bild published an article saying that one of the diesel vehicles the automaker would emit 11 times more NOx the European standard.
In an official statement responding to Auto Bild, BMW said it “does not manipulate or adulterous gas emission tests.”
