Diesel only with a Cheat software, but also a lot of gasoline Cars, the exhaust gas limits are exceeded often. The reason for this is hardly effective cheap catalysts - a Problem that is loud Report Mainz known for years.
Older gasoline vehicles contribute significantly to air pollution, have revealed research by Report Mainz. The reason for this faulty Replacement catalytic converters, which are sold on the German car-parts market in mass.
Original catalytic converters must be replaced after a certain period of time - cheap products but often have a significantly lower efficiency.
measurements of the German environmental aid, the Report Mainz has accompanied with the camera, show that these catalysts are Cheap exceed the limit values for nitrogen oxides considerably. "Only the high-quality catalyst has complied with the limit. The cheap-Kats are all far above the limit," explains the project Manager of the German environmental aid, Simon Annen.Similar to many nitrogen oxides as a cheat diesel
Some of the models were the nitrogen oxides emissions in the range of the manipulated diesel vehicles. "The Problem is that we measure at the exhaust emission test (AU), no nitrogen oxides. That is, if a catalyst in this area does not work, can not attract attention," said Thomas Schuster from the Car-testing organization KÜS.
the Team from Report Mainz was able to show that a VW Passat, despite the lack of a cheap catalyst inventory without any problems of the AU. "That is, of all things, the substance (oxides of nitrogen), the Republic of discussed for years, is not measured in the exhaust measurement. This is of course unacceptable and should be urgently changed," criticized the green transport politician Oliver Krischer.Mass is a Problem
"catalysts lose to an average of around eight years or 80,000 kilometres of their performance," says Philipp Schulte, managing Director of the German cat-manufacturer HJS. Then you need to be against a replacement catalyst is replaced. This market is dominated by cheap catalysts from Spain and England, "we estimate that three-quarters of the market, cheap catalysts, is increasing. The prices dominate the market," says Schulte.
In the case of the exhaust investigation is not measured in nitrogen oxide emissions.
be sold to A catalyst manufacturer from Baden, quoted from a market analysis, according to per year up to 900,000 cheap-catalysts in Germany. At Online retailers and ebay platform, there are tens of thousands of offers for virtually all of the gasoline vehicle models.Saves a precious metals
Without a functioning Three-way catalyst petrol vehicles emit very high concentrations of nitrogen oxides. But the precious metals used in catalytic converters to reduce the pollutants normally. The use of platinum, Palladium and Rhodium.
the Latter is the most expensive of the three precious metals, and provides for the reduction of nitrogen oxides. According to the German cat-manufacturer of a precious metal coated interior costs a part of a catalyst for more than 100 Euro, the entire cat is between 300 and 500 euros.
But, the cheap catalysts are offered as complete sets including all pipes on the Internet from as low as 50 Euro. "Because you have to assume that a serious component cannot be made for the price," explains Schulte.Own analysis of the Report Mainz
Report Mainz has a widespread cheap catalytic Converter for a VW Golf in an independent laboratory study. The results were clear. The catalyst contained only metals 0.1 grams of precious. In a identical Qualitätskat from Germany, the salary was ten times as high. When the nitrogen oxides, the major Rhodium Billigkat even had only a Thirtieth of the necessary amount.
experts are now calling for that in addition to the emission inspection (AU) also, the approval for catalysts improved not needed to be so poor Kats come out on the market.Problem authorities is known for years
The research by Report Mainz coincide with the results of a study of the "Bundesanstalt für straßenwesen" (BASt) to the year 2015. Experts of the BASt had purchased several inexpensive catalysts covered and investigated. Some models were already in a new state far in excess of the permitted nitrogen oxide limit values, the other failed after 10,000 or 40,000 kilometres of driving performance.
"The Problem is the authorities, therefore, been known for years, but the Ministry of transport has done nothing at all", criticized the Green traffic expert Krischer. For an Interview, you will not stand at the Federal Institute. The Federal Ministry of transport, confirmed Report Mainz in writing that there is problems with "insufficient quality of Replacement catalytic converters".
in An Interview on the subject also the force travel Federal office and the Ministry of transport refused. These catalysts have approvals in the EU and, therefore, the German authorities had their hands tied. A national legal alone was in breach of the applicable EU rules for the internal market, the Ministry of transport.
