Volkswagen has offered the transport authority of Germany (KBA) a proposal to be able to “legalize” the 1.6 TDI CR affected by the scandal of the emissions of oxides of nitrogen. This problem goes to the margin of the fuel consumption and CO2 emissions over and above what was initially announced. The NOx pollute, CO2 is a greenhouse gas.
The German brand, along with SEAT, Skoda and Audi, have to call in to fix all the engines affected family EA189 to drastically reduce their emissions. In the case of the 1.2 TDI and 2.0 TDI, it seems that just a reprogramming to enrich the mixture. This will lead to increased consumption, a higher temperature of combustion and more efficient operation of the catalyst of NOx.
with Respect to the 1.6 TDI, the solution is a little more complex. For the moment we know, by the mouth of the “boss” (Matthias Müller), will have to change the injectors of diesel fuel and the catalyst, by another of greater capacity. In addition, there will be a reprogramming of the ecu.
it is Not known how long it will take the KBA in authorizing these changes, but even if it is fast, the agreement would be delayed for months. It is necessary to get providers to a huge volume of parts, and not produced from one day to another. We are talking about millions of catalysts and the quadruple of millions of injectors.
The intention of Volkswagen is to start putting a hand in the engines affected by the scandal from the year that comes. The brands of the VAG Group will be putting in contact with the owners to give them more information about the process. The 1.6 TDI probably can’t be “repaired” until September 2016.
