29. Europäische Abgasnorm
Eine europäische Abgasnorm, meist als Euro-Norm bezeichnet, ist eine europäische Fahrzeugklassifizierung auf Grundlage von Grenzwerten für Schadstoffe, die von Fahrzeugen und ihren Motoren ausgestoßen werden. Aufeinanderfolgende Normen wie Euro 4, Euro 5 und Euro 6 führten schrittweise strengere Anforderungen für Schadstoffe wie Stickoxide, Feinstaub, Kohlenmonoxid und Kohlenwasserstoffe ein.
Die Euro-Norm eines Fahrzeugs wird im Rahmen seiner Typgenehmigung festgelegt und hängt unter anderem von Fahrzeugkategorie, Kraftstoffart und den zum Zeitpunkt der Genehmigung geltenden Emissionsvorschriften ab. Euro-Normen können von Behörden auch zur Regelung der Zufahrt zu Umweltzonen verwendet werden; die örtlichen Zufahrtsregeln unterscheiden sich jedoch zwischen Ländern und Städten.
What is a European emission standard?
A European emission standard, or Euro standard, classifies vehicles according to the emissions requirements they had to satisfy when approved for use in the European market.
What do Euro 4, Euro 5 and Euro 6 mean?
They are successive generations of European emission requirements. In general, a higher Euro number represents a newer and stricter emissions standard, although the exact limits differ according to vehicle and fuel type.
Which pollutants do Euro standards regulate?
Depending on the vehicle and standard, limits apply to pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons. Newer standards also regulate additional environmental aspects.
Is the Euro standard the same as a vehicle's CO2 emissions?
No. Euro standards primarily regulate harmful air pollutants from vehicles. Carbon-dioxide emissions and fuel or energy consumption are subject to separate measurements and regulatory requirements.
How can you find a vehicle's Euro standard?
The Euro standard may appear on the vehicle registration certificate, certificate of conformity or other official vehicle documentation. Its location and format vary between countries.
Does the year of a vehicle determine its Euro standard?
The date of first registration can provide an indication, but it does not always determine the standard with certainty. The official vehicle documents or type-approval information provide the more reliable classification.
Can petrol and diesel vehicles with the same Euro number have different emission limits?
Yes. The applicable emission limits and testing requirements can differ according to the vehicle category, engine and fuel type even when vehicles belong to the same general Euro generation.
Can the Euro standard affect access to a low-emission zone?
Yes. Many low-emission zones use the vehicle's Euro standard together with factors such as fuel type and vehicle category to determine whether it may enter.
Does installing a particulate filter automatically change the Euro standard?
Not normally. The official Euro standard is linked to the vehicle's approved emissions classification. Retrofitting emission-control equipment does not necessarily result in a different official Euro classification.
What is Euro 7?
Euro 7 is the latest European emissions framework for road vehicles. It builds on earlier Euro standards and also introduces requirements covering areas such as non-exhaust particle emissions and battery durability.
