EURO 4 fuel refers to a set of European emission standards that were implemented to reduce harmful emissions from vehicles. Introduced in 2005, EURO 4 regulations require lower limits for pollutants such as nitrogen oxides (NOx), hydrocarbons, and particulate matter in both petrol and diesel fuels. The standards encourage the use of cleaner fuels and more efficient engines to improve air quality and reduce environmental impact. Compliance with EURO 4 is mandatory for new vehicles sold in the European Union.
