{2.09.15}A corporate brand that stands for reliability and value got a rude shock this week when it was revealed Volkswagen cheated on emissions test to get its popular diesel engine models accepted by regulators. The company's CEO, Martin Winterkorn has already resigned and more resignations by company executives are expected. The cheating is international in scale with as many as 11 million diesel vehicles containing software that allowed the company to evade pollution standards in the United States. An independent investigation by CAFEE, Center for Alternative Fuels, Engines and Emission detected the software "fix" when it was asked to study US models of European diesels under US conditions since these vehicles were emitting 4-7 more pollution than permitted under less stringent European standards. The US Justice Department is now beginning a criminal investigation.
The New York Times reports that VW diesel engine models as well as Audi models made by VW contained programs for detecting when the engine was undergoing emissions testing. The programming turned on all of the vehicles exhaust scrubbing mechanisms to insure a passing score and then turned them off when testing was completed, allowing significantly more pollution to enter the atmosphere than detected. The standard at issue is the NOx, or nitrous oxide emissions that is noticeably more stringent in the US than Europe (0.04g/km compared to 25g/km). Nitrous oxides are responsible for creating smog and depleting the ozone layer.
