The entry ban for cars not meeting a specific combustion standard is aimed at limiting the emission originating from transportation, and as the result, improve the air quality. Therefore, the EURO 5 standard was a step forward to this goal.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As it is explained in the article concerning the clean transport zones, entering the SCTs is gradually limited.

In the case of EURO 5, there has been certain distinction. The \u201cfifth version\u201d of the popular standard embraces:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>light passenger and utility cars <\/b><span style=\"font-weight: 400;\">(in accordance with the Regulation no. 715\/2007),<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>two- and three-wheel vehicles <\/b><span style=\"font-weight: 400;\">(following the Regulation no. 168\/2013).<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The EURO 5 standard is therefore applied to passenger cars (the M category) with diesel and gasoline engines, motorcycles and three-wheel vehicles (the L category), and light utility vehicles (the N1 and N2 categories). For truck and buses separate regulations were prepared, i.a. due to the fact that the manner of presenting the harmful substances emission changed (not in grams per kilometer, as it was until then, but in grams per kilowatt-hour).<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_SCR\"><\/span><b>What is SCR?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Increasingly more rigid new standards forced the manufacturers to look for advanced and ecological solutions. One of the examples of this is introducing the SCR system to vehicles with the diesel engines. The role of the <\/span><b>SCR, selective catalytic reduction<\/b><span style=\"font-weight: 400;\">, is to limit the harmful substances emission, in this case nitrogen oxides.<\/span><\/p>\n<p><b>How does the selective catalytic reduction work?<\/b><span style=\"font-weight: 400;\"> The AdBlue fluid is injected under pressure to the initial section of the exhaust system.

When in comes to the diesels meeting the EURO 5 criteria, the SCR catalysts were not yet used on a daily basis. The spread of these catalysts was accelerated by the EURO6 standard, which allows substantially lower share of NOx in emission.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This piece of technology is not free from flaws \u2013 and a vehicle equipped with the SCR catalysts might cause problems, especially in winter (the AdBlue fluid freezes already at -11\u00b0C). Any abnormalities in the system performance might result in the necessity of having expensive repairs done, and also the engines performance might be disrupted.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_EGR\"><\/span><b>What is EGR?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Another way \u2013 aside from SCR and the particulate matter filters \u2013 to improve the emission parameters used by the vehicle\u00a0 manufacturers is the <\/span><b>EGR system <\/b><span style=\"font-weight: 400;\">(Exhaust Gas Retention), <\/span><b>which one of the elements is the well-known to the drivers EGR valve<\/b><span style=\"font-weight: 400;\">.

It is of more importance when the car is driven often for short distances, when the engine does not heat up well. This is one of the reasons why diesels are not recommended for drivers who drive purely in the cities and almost never on longer distances.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_future_of_the_EURO_5_standard\"><\/span><b>The future of the EURO 5 standard<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The cars currently registered must meet the criteria of the EURO 6 standard.
