Diesel Euro 5: what it means and which cars are involved

But how it is established if a car is Euro 5? When it is produced and registered, each car receives one environmental classificationmade based on its emissions of climalterant gases, including the carbon monoxide (CO) they nitrogen oxides (NOX). In particular, the Euro 5 cars are those registered between the 2011 and 2015.

In general, the environmental classes range from Euro 0the most dated, to Euro 6the most recent: in other words, the lower the euro class number, the more polluting the car, which, consequently, can be subject to circulation limitations.

But because the provision concerns only the Diesel car Euro 5? The answer is very simple: why pollute about three more times Compared to a petrol car. In particular, the limit values ​​established by the EU for Diesel vehicles Euro 5 I am:

  • 180 mg/km Of nitrogen oxides (Nox), triple compared to the Euro 5 petrol vehicles, which emit 60mg/km.
  • 5 mg/km Of particulatejust like petrol.
  • 500 mg/km Of carbon monoxide (CO)the only lower value than petrol cars, which emit 1000 mg/km.

Just to have a comparison, cars Diesel Euro 6 the issue of 80 mg/km of nitrogen oxides (NOX), less than half compared to Euro 5.

How to know if the measure also concerns our vehicle

But how to know if the decree also concerns the own vehicle? The Ministry of Infrastructure and Transport refers to Motorist portalwhere you can check the euro class of your car by inserting the plate and indicating the type vehicle. In addition to specifying the environmental class, the portal also indicates the pollutant emissions values. Alternatively, all data on the vehicle are however reported within the registration book.
