The European Parliament, against the reduction of NOx limits

The European Commission proposed on the 28th of October, through a
technical commission, increase to 110% of the amounts of oxides of
(NOx) that cars will be able to issue after undergoing a test
emissions on the open road. That meant climbing de facto the limit of 80 mg/km to 168 mg/km, more than double of what is allowed today.

The European parliament had to approve the draft of the proposal, and
shot yesterday with 40 votes against 9
, and 13 abstentions. From 18 to 21
January a vote the draft on session conventional. Of the 751
parliamentarians, if there is a simple majority (376) shall exercise the right
of veto, and the proposal will be annulled

Had a
pre-proposal, giving a margin in excess of 60% and not 110%, up to
2019. From then on, it would allow a 20%, versus 50% that
asked for the final draft. If the Parliament vetoes the last draft, are going to
disappear engines Diesel market to tens
, as it fears the employer’s automobile ACEA.


Reductions theoretical of nitrogen oxides since 2001. Have not been met

let’s recap
a little
. Currently the cars are tested and align using a
cycle of circulation in the laboratory (NEDC), nothing realistic. The limits of
emissions must be met in these conditions. To be able to sell a
internal combustion car in Europe, can’t get past 80
milligrams per mile

As the measuring apparatus
portable (for use on open road) have a margin of error, there is that
raise the figure of 80 mg/km According to the press note issued by the
The European parliament, the average error is 18.75%, and how much you spend
30%. Therefore, it is not strictly necessary to give more margin
30%, the 110% is the triple.

The real reason of the increase of
requires the second draft has as its objective that, with the new
approvals, are not many Diesel models outside of the
legality. In testing outside the laboratory, as the engineers will not
can control the variables in the same way, the results are
always higher. Almost all countries voted in favour of raising the limits in the technical committee, especially those that have car factories on their soil.


Comparison of the current boundaries, and proposed, on both occasions, to be able to overcome them with road testing

According to the data of the
it did, the pollution of the air, of whatever kind, takes
430.000 lives annually in the EU, with a cost of approximately 940,000
million euros. premature deaths directly associated to the
NOx are to 75,000 per year in Europe. In Spain they are 5.900 fatalities by pollution, almost six times more deaths than in traffic accidents on the roads.

reasons have to import more than the commercial performance of the
manufacturers of cars. If the Diesel engines will not meet the legality,
will have to do as the americans at the end of the 70: legalizarlos
although lose benefits. And gasoline engines is still there to choose them.

historically, it has benefited to the Diesel engine for its lower consumption of
fuel (oil) and for its lower CO2 emissions.
