Witch-hunt: the us EPA tested the emissions in the movement of all cars diesel

The scandal of the TDI in the Volkswagen Group – which has branched out and has revealed that 800,000 cars distorted to lower the data consumption approved – has had a serious impact in the industry. Impact that the regulators are not unrelated. A game of “who made the law made the trap” carried to the extreme, so to speak. The game has ended, and the , EPA american has announced that will test the emissions on movement of all cars diesel to avoid future problems.

The director of air quality of the , EPA says that the agency must think as they do cheats to detect possible fraud.

, EPA has been the organization that uncovered the fraud of the over-issuance of oxides of nitrogen engine 2.0 TDI of the Volkswagen Group, as well as in the 3.0 TDI, just a few days ago in this latter case. The European Commission has already voted to create approval testing of consumption and emissions in circulation, which will commence in 2017. The Commission is bowing to the auto industry, but the , EPA does not follow the same path, and has already begun random testing to determine if more vehicles do not comply with the established limits.


The tests are performed in circulation, with portable equipment for measurement of emissions. The cars chosen are models 2015 and 2016 of all diesel passenger cars sold in the united States, from the Chevrolet Cruze turbodiesel BMW 420d, passing by all the cast of the Volkswagen Group, the leader in sales of vehicles with diesel engines in the united States. , EPA has not communicated the testing procedure, fearing that manufacturers begin to plan ways to alter the emissions of the vehicles.

, EPA measured from years ago, emissions in the road of the big trucks, but not passenger cars.

But we do know that there are vehicles of pre-production such as those employed in Europe to accredit consumption and emissions. This eliminates the danger that the manufacturer of the vehicle “fits” the test to achieve figures below the real. The , EPA ask vehicles provided to dealers, vehicles of the press to the manufacturer and even will use customer vehicles. In this last case, the customer will be compensated with 20$ a day, a full tank of fuel, an oil change and a replacement car.


The objective of this “witch hunt” is to detect vehicles that distort their emissions in circulation. To detect the presence of other “defeat devices” by detecting a level of emissions – oxides of nitrogen – excessive in comparison to that measured in the laboratory. Of course, you know that the emissions in the movement of the car will be higher than the approved, but looking for large deviations. As the detected in some 2.0 TDI, up to 40 times higher than those detected in the laboratory.

The “Dieselgate” shall promote the adoption of hybrid and electric vehicles for the american consumer.

These tests will also affect older vehicles, with the simple objective to check if their systems anti-pollution continue to operate effectively. The result of this thorough examination of diesel vehicles on sale in the united States will be published in a few weeks. The , EPA is no stranger to this type of evidence: for years, they measure emissions in the movement of large trucks. The results will demonstrate whether other manufacturers are doing traps, or has only been the Volkswagen Group.


on A personal level, I think that this witch hunt will have clear results: to dissuade the american consumer from the use of cars with diesel engine. It is clear that it is a good time for companies that have focused their future on hybrids and electric. Also, I think that this crisis has been a wake-up call important to the industry, as well as to regulators. And it seems that finally the government agencies have realized that their approval procedures, favor this kind of traps.

If you are going to an exam and know the answer to the problem, you just have to develop a procedure to get to it. The random factor you should avoid this kind of traps. And for once, Europe should take note of the united States.
