Key word: euro 6

What is Euro 6?

The Euro 6 standard is a set of regulations introduced by the European Union to reduce emissions from road vehicles. It was introduced in 2016 for light-duty vehicles and at the end of 2013 for heavy-duty vehicles. It aims to limit emissions of polluting gases such as nitrogen dioxide (NOx), fine particulates (PM) and hydrocarbons (HC) from diesel engines. It also sets limits for carbon monoxide (CO) and nitrogen oxide (NOx) emissions from gasoline engines. There are variants of this standard for light and heavy-duty vehicles, based on the same principles but with different emission limits.

The deletion of the following elements included in the Euro 6 standard

- Selective catalytic reduction (SCR) to reduce nitrogen dioxide (NOx) emissions in diesel engine exhaust gases.
- Particulate filter (FAP) to reduce emissions of fine particles (PM) in diesel engine exhaust gases.
- The EGR (exhaust gas recirculation) valve to reduce emissions by burning exhaust gases a second time.
