Method of measurement the emission of nitrogen oxides from passenger cars needs to be better

The European parliament that there will be no difference anymore between the emissions of oxides of nitrogen (NOx) from cars, as measured in the laboratory as well as the actual emissions during the journey. Over two years have deviations in the past.

to this End, the European Parliament decided earlier this month. In this way, a start has been made on the reduction of the number of fijnstofgerelateerde-induced deaths reported in Europe. According to the European environment Agency (eea) every year up to 400,000 people to an early death, especially in the Central and Eastern european countries. Cars are designed according to the European agency, responsible for 40 percent of the total NOx emissions in the EU.

if The European Parliament wants to make sure that you have the emissions from passenger cars in the EU, to meet your requirements. In order to test it, is to move away from taking measures with a laboratoriumsetting, and will be called the Real Driving Emissions (RDE) tests have been introduced. In this way, the actual emissions produced during the drive can be measured.

It is done by means of a portable emissiemeetsysteem during a test drive in the car mount. The standards for these measurement issues by the European Parliament has now tightened up. This is to avoid the cars that are on paper and are very clean, seem to be, in practice, it is much more emissions, have to. This anomaly needs to be more precise, on september 30, 2022, it is gone.

set Against the backdrop of the dieselschandaal

The step comes from the on-going discussion about the dieselschandaal that in 2015 with the Volkswagen, it was discovered. The company applied a special software that allows the on-board computer of a vehicle, a laboratory test was able to identify it. In that way, the level of NOx emissions is artificially kept at a low level will be.

the models from Audi, Porsche, Skoda and Seat were also involved. Later on, they were anomalies found in cars like BMW, Daimler, Jeep, Opel, and Suzuki. Also from the Nissan, Mitsubishi, Peugeot, and Renault have been allegations of manipulation with the commission. Last week there were raids in to the Fiat Chrysler Automobiles due to the possibility of the application of the sjoemelsoftware.

with The introduction of the T-tests, and the use of a portable emissiemeetsystemen some of the recommendations made by the Enquetecommissie emission measurements in the automotive industry from 2016 onwards.

Despite the fact that modern diesel engines meet the stringent Euro-6d-temp, which is the current European uitstootnorm, compliance today is much less of NOx emissions, the dieselkrachtbron suspect. Earlier this year, it was found that the cleaning of the dieselpartikelfilter (DPF), significantly more particles (P) are released than you are allowed.

in the end, the legal limit for PM emissions per kilometer of between 32 and 115 percent, exceeded, during the so-called DPF regeneration. As well as the most sophisticated ultrafijnstof (particles of about 10 nm) is taken into account, the fall in emissions between the 11 and 184 per cent higher.

the results of the independent not-for-profit organisation, Transport & Environment and conducted by the British engineering firm, Ricardo, showed that of the 45 million diesel cars, such partikelfilters in the EU, on an annual basis to 1.3 billion euros, of such reinigingssessies.

now, The researchers have proposed to use the so-called Euro6d auto-diesel engines are no longer as 'clean' label.
