Diesel engines are justified: they pollute nothingFebruary 23, 2019
Modern diesel cars, according to new research, almost do not emit nitrogen oxides. For example, the BMW 520d emits only 1 mg / km with a permitted limit of 168 mg / km.
The German Automobile Club (ADAC) conducted road tests of the RDE (real emissions while driving) of a number of gasoline and diesel models to evaluate their cleanliness, and found that the emissions of many models are well below the permissible 168 mg / km (according to Euro 6d Temp rules) .
The Mercedes C-Class C220d diesel didn’t actually release NOx (nitrogen oxides) during road tests, the BMW 5-Series emitted only 1 mg per kilometer, the Opel (Vauxhall) Astra with its 1.6-liter diesel engine also impressed, throwing out only 1 mg / km, and Citroen Berlingo BlueHDI 130 – only 7 mg / km. In some cases, proven diesel cars produced less NOx than equivalent gasoline models.
It is not known how manufacturers achieved such low NOx emissions, but they did, and the results are now definitely not falsified.
NOx emissions have been at the center of discussions on diesel fuel over the past few years, researchers attributed the harm they cause to asthma, a number of lung diseases, heart disease, and dementia.
From January 2020, the compliance ratio of nitrogen oxides is reduced by 1.5 times, which will allow diesel vehicles to emit no more than 120 mg / km NOx during the RDE tests.
