- The monitoring of emissions of gaseous pollutants, outside the official measurement cycle, is a subject that has been brought to the attention of the European Commission for several years. As a result, several technical committees at EU level have studied the impact and concluded that a legislative change is needed to avoid excessive emission overruns in real-world operation, outside the cycle. The legislative amendment has passed the EC’s opinions, is under discussion at EU level and involves an alternative method of measuring with equipment crafted in the vehicle and in real operation on the road. The method prevents the risk of having situations equivalent to those in the USA, i.e. that manufacturers program the engines’ computers for an advantageous operation on the official measurement cycle, compared to the actual operation of the vehicles. The new set of measures is generically called RDE (Real Drive Emission).
- The principle of market admission for new vehicles, between the EU and the USA, differs fundamentally, the procedures being based on other principles:
- in the European Union, the type-approval principle granted by an independent, third-party authority applies, which involves:
– testing the type of vehicle before placing on the market,
– the granting of a type-certificate;
– conformity of production monitoring;
- in the United States of America the principle of self-certification (self-certification) is applied, by which:
– the manufacturer carries out the tests himself,
– the manufacturer declares to the authority that he complies with the requirements;
– the authority grants the right of sale on the basis of the declaration;
– the authority shall subsequently verify that the requirements have been met.
As in the present case, if non-conformities are found, the authority takes measures and sanctions the manufacturer.
From the difference in the two principles of market admission it can be concluded that the EU variant has a higher degree of prevention for the placing on the market of vehicles with problems. At the same time, the US version allows problems to be applied to more drastic sanctions after the detection of problems.
- We mention that Volkswagen vehicles for Europe have the Community approval granted by the German authority, and not by the Romanian Auto Register. According to European legislation, responsibility for ensuring the conformity of production lies with the authority which issued the approval.
