The constraints related to the environment, the vehicle’s pollution, as well as the increase in the number of the registered vehicles have to lead to the development and implementation of complex systems for the treatment of exhaust gases. The pursued purpose of the given regulations and environment norms has been the decrease of the main pollutants measured at the vehicle’s exhaust pipe, that is: the nitrogen oxides, particles, carbon monoxide. This paper presents the experimental research and the results obtained on the influence of the solution AdBlue on the pollution performances – studies that have been achieved at Volvo Romania SRL. Thus, taking into consideration the evolution of the temperature of the reductant from -40°C to +40 °C, there are underlined the performances insured by SCR and the dependency of the pollutants on these temperatures, fulfilling the usual usage measures. The variations recorded for nitrogen oxides (after the catalyzer for catalytic reduction), the reductant consumption and the efficiency of SCRtransformation at different values of the AdBlue solution are being presented using graphic representations.
