Use of AdBlue has been common on trucks and buses since 2006 following the introduction of Euro4 regulations for those vehicle classes.

This was followed by the introduction of Euro6 emissions regulations targeting a number of harmful gases linked to public health.

The rules focus on nitrogen oxides (NOx) and have cut the permissible limits for NOx to 80mg/km. This is aimed at reducing emissions and limiting the environmental impact of Diesel Vehicles.

AdBlue is a synthetic urea which works by turning nitrogen oxide into harmless steam and nitrogen. It is stored in a tank, like fuel, certain manufacturers refer to it as ‘Emissions Additive’.

AdBlue is not injected into the engine as a fuel additive. It is added to the catalyst system in the vehicles exhaust system.
