The German manufacturers have with their “clean diesel” in America providing for certain restlessness and caused a remarkable decision.
The software used Volkswagen for manipulating exhaust emissions in its diesel engines, comes after information of FAZ.NET from the year 2005. At that time, the German automotive industry, including Volkswagen , Mercedes-Benz, Audi and BMW set out to make the modern diesel engines in the United States presentable. In 2005, Bernd Pischetsrieder Chairman of the Board of Volkswagen Ferdinand Piech and were Chairman of the Board. Martin Winterkorn, who is a recognized technology specialist, has taken over as CEO of VW in 2007 and held it until today.

The Initiative drives them to this day, with the support of the Association of the Automotive Industry VDA and moderate success ahead. Volkswagen does have several hundred thousand passenger cars with diesel in the market, but in the upper class, the proportion of self-igniting unit is negligible. Mercedes-Benz sold about only 700 cars with diesel per month in North America.
The American automakers keep from Diesel nothing, which is why time and again the suspicion is expressed, it’ll go in the official crackdown on Volkswagen also order a to protect the domestic industry. After all, the German manufacturers have taken care of her so baptized “Clean Diesel”, which is touted as the answer to there also stringent guidelines for certain restlessness and caused a remarkable decision. General Motors has recently reintroduced for the first time after thirty years of abstinence a passenger car diesel engine in his Chevrolet Cruze model.

As a special selling point should and should apply the low emissions, which is below even the most stringent limits in California. Apparently that’s the engineers of Volkswagen solely by technical means not fully succeeded. Although the contract at issue four-cylinder diesel reaches low limits, but apparently not particularly low standard SULEV (Supra Ultra Low Emission Vehicles), stage. 2
Then why not only the American Motors, but 11 million engines are fitted around the world with the offending software, nor can at Volkswagen nobody quite explain. Because according to the current state of knowledge of the engine within the required limits achieved in most countries without any cheating. Maybe a whole package was simply programmed out of the required parts have been activated.
That would certainly have happened in Wolfsburg and not, the plight to report secretly at a banging to their professional future troop in America who did not dare to headquarters. ECUs are today “flashed” until the end of the tape the car manufacturing facility with control software, there also the typical adaptations are made. Maybe it already went there to internal cover-up. You could use the code in the relatively extensive program hiding, without notice.
mandatory if a manufacturer wants
In the United States it is after all what we know so far, to the particularly strict emission standards SULEV, Level 2. The California Air Resources Board has you advertise 2004 introduced. Compliance is only mandatory if a manufacturer wants to advertise. The Volkswagen has done the first time with the introduction of the new Jetta TDI in 2011th An indirect constraint is the fact that it also for exhaust emissions are in California fleet limits, not only for CO2, as in this country. The first valid only for California limits have now adopted many but not all American states.
In the present case it is, however, only to the emission of nitrogen oxides (NOx) of the 2-liter TDI engine. The SULEV NOx limit is 0.02 g / mile considerably below the European standards of 0.08 g / km. In addition, he is currently in force in the European driving cycle easily observed than in the United States. After all, the “Federal Test Procedure” provides higher average speeds and greater acceleration before -. Both have influence because under acceleration device of the chemical process of emission from the balance
For extremely low values an aqueous urea solution (trade name AdBlue) must be injected to the fuel, drivers of modern diesel engines know that in this country. Their cars have next to the filler neck a second, mostly blue filler neck for AdBlue. Particular attention of the driver is not necessary, however. The consumption of AdBlue is generally so low that the solution is replenished as part of normal service intervals.
standard cycle should only establish a comparability to do
Not have the allegations with the deviation of consumption in the standard cycle and in everyday use. The standard cycle is only intended to establish a comparison, so the customer can decide whether he wants to buy about a VW Golf or Opel Astra. The actual fuel consumption depends greatly on the personal driving style from.
What does the approach of Volkswagen illegal, is the fact that the capitalized software (Defeat Device) detects whether the vehicle in the test cycle runs and – due to technical reasons onset with a time lag – Emission Control adjusts foresight on what not in everyday use succeed. This call professionals cycle detection.
And that is illegal. In America as in Europe. Volkswagen has not only himself overthrown by the manipulation in a crisis of confidence, but the whole industry with the same. There is asserted to comply with all laws. “Such manipulation has not given it to us and are not there. At Mercedes-Benz, none of the so-called defeat devices are used, “said Daimler spokesman Jörg Howe.
