Key word: euro 5

What is the Euro 5 standard for heavy goods vehicles?

The Euro 5 standard was introduced in October 2009. The Euro 5 standard for heavy-duty vehicles requires truck and bus manufacturers to reduce emissions of pollutants such as fine particles and nitrogen monoxide. To achieve this, they can use techniques such as EGR (Exhaust Gas Recirculation) or SCR (Selective Catalytic Reduction). The EGR technique consists of reintroducing part of the exhaust gases into the engine to lower combustion temperature and reduce nitrogen oxide emissions. SCR, on the other hand, uses a urea resin called AdBlue® to treat exhaust gases and convert nitrogen oxides into water vapor and harmless nitrogen.
