    EPA, California Notify Volkswagen of Clean Air Act Violations / Carmaker allegedly used software that circumvents emissions testing for certain.

    «Volkswagen» переводится с немецкого языка как «народный автомобиль». Первая партия автомобилей, выпущенная на заре становления компании, составляла всего 12 штук. Во время нацизма логотип компании был изменен и стилизован под свастику.

    2: EPA and CARB notify VW of additional Clean Air Act violations, this time in about diesel emissions, chalking the violations up to a misunderstanding of the Repurchasing the roughly 80, affected vehicles would add several billion.

    Car owners should know that although these vehicles have emissions exceeding standards, these violations do not present a safety hazard and the cars remain legal to drive and resell.

    NACS | EPA Notifies VW of Additional Clean Air Act Violations

    The agency had found that Volkswagen had intentionally programmed turbocharged direct injection TDI diesel engines to activate their emissions controls only during laboratory emissions testing which caused the vehicles' NO x output to meet US standards during regulatory testing, but emit up to 40 times more NO x in real-world driving.

    Among them was a group of five scientists at West Virginia University , who detected additional emissions during live road tests on two out of three diesel cars.

    ICCT also purchased data from two other sources. The new road testing data and the purchased data were generated using Portable Emissions Measurement Systems PEMS developed by multiple individuals in the mid-late s and published in May Regulators in multiple countries began to investigate Volkswagen, [28] and its stock price fell in value by a third in the days immediately after the news.

    In January , Volkswagen pleaded guilty to criminal charges and signed an agreed Statement of Facts, which drew on the results of an investigation VW had itself commissioned from US lawyers Jones Day. The statement set out how engineers had developed the defeat devices, because diesel models could not pass US emissions tests without them, and deliberately sought to conceal their use.

    The "unprecedented" plea deal formalized the punishment which VW had agreed to. The scandal raised awareness over the higher levels of pollution emitted by all diesel-powered vehicles from a wide range of car makers, which under real-world driving conditions exceeded legal emission limits. A discussion was sparked on the topic of software-controlled machinery being generally prone to cheating, and a way out would be to open source the software for public scrutiny. In general, three-way catalytic converter technology, which has been very effective since the early s at reducing nitrogen oxide in petrol engine exhaust, does not work well for diesel exhaust because of its relatively high proportion of oxygen.

    In , parts of VW intended to purchase the rights to Mercedes ' BlueTec system for reducing pollution, but other parts of VW rejected that and preferred to develop their own system. Starting in the model year , Volkswagen Group began migrating its light-duty passenger vehicle turbocharged direct injection TDI diesel engines to a common-rail fuel injection system.

    This caused the engine to emit NO x levels above limits in daily operation, but comply with US NO x standards when being tested, constituting a defeat device.

    The award was rescinded in early October In , a Swedish researcher criticized the New European Driving Cycle standard for allowing large emission differences between test and reality. The project was shut down in , despite preliminary tests indicating gaps between emissions from lab tests and real world tests of about 10 to 20 percent.

    In , the European Commission's Joint Research Centre published a report which found that all tested diesel vehicles emitted 0. Sensors and electronic components in modern light-duty vehicles are capable of 'detecting' the start of an emissions test in the laboratory e. Some vehicle functions may only be operational in the laboratory, if a predefined test mode is activated. Detecting emissions tests is problematic from the perspective of emissions legislation, because it may enable the use of defeat devices that activate, modulate, delay, or deactivate emissions control systems with the purpose of either enhancing the effectiveness of these systems during emissions testing or reducing the effectiveness of these systems under normal vehicle operation and use.
