Diesel engines were much more harmful than gasolineSeptember 22, 2019
According to the results of a new study, diesel engines that meet the Euro-6 standard are almost 5 times more dangerous than gasoline engines.
The study, which was conducted by the International Council at the request of the Paris City Hall, affected over 180,000 cars. Experts measured the amount of harmful substances in the exhaust of a car in three different places in Paris and simultaneously recorded the year of manufacture and type of engine.
As it turned out, even those diesel engines that meet the current environmental standard Euro-6 are much more harmful than modern gasoline power units of the same standard.
It is noted that heavy-fuel engines emit 4.8 times more toxic substances into the environment and are only 18% cleaner than gasoline engines of the previous eco-standard.
Euro-5 and Euro-6 diesel engines account for 63% of the total level of environmental pollution with nitrogen oxides resulting from the use of ICE machines.
French ecologists were also concerned about the fact that the indicators of changes in the level of emissions in real conditions differ from laboratory results by more than 6 times. Probably, nitrogen oxide emissions increase sharply in hot weather.
