New and increasingly sharp laws for the reduction of emissions from commercial vehicles entered into force in the European Union since 1993 with the aim of substantially reducing pollutants and emissions from trucks and buses.Thereby the maximum levels for the emission of particulate matter(basically soot particles)as well as oxides of nitrogen(NO_x)have been subsequently lowered.To comply with these demands,commercial vehicle producers had to introduce new emission reducing technologies of which exhaust-gas recirculation(EGR),selective catalytic
New and increasingly sharp laws for the reduction of emissions from commercial vehicles entered into force in the European Union since 1993 with the aim of substantially reducing pollutants and emissions from trucks and buses. Whoby the maximum levels for the emission of particulate matter (substantially soot particles ) as well as oxides of nitrogen (NO_x) are in the demands of such demands, commercial vehicle producers had to introduce new emission reducing technologies of which exhaust-gas recirculation (EGR), selective catalytic
