Volvo has chosen SCR technology to meet the Euro 4 and Euro 5 exhaust emission standards – just as the vast majority of western European heavy truck manufacturers have done.
In order to meet the Euro 4 emissions requirements that were introduced in Europe in 2006 and the coming Euro 5 standards (2009), new solutions are required for diesel engines, combustion processes and exhaust after-treatment techniques.
Volvo is at the very forefront as regards the development of exhaust reducing techniques. Our solution for meeting the Euro 4 and Euro 5 requirements is diesel engines with even more efficient combustion, along with after-treatment of exhaust gases using the AdBlue additive and SCR (Selective Catalytic Reduction).
