The paper includes information concerning the possibility of emission of noxious components of fumes due to the use of the advanced system of fumes recirculation in the farm tractor engine equipped with an innovative supply system basing on classical solutions of a high-pressure injection pump. Moreover, the paper includes the concept of the advanced fumes recirculation system. The use of a new type of EGR valve that regulates the amount of fumes which are returned to an engine, cooperating with an integrated sensor O₂/NO_x placed in the outlet collector allows effective use of a configuration of the particular engine with a fumes cleaning system. The paper presents the results of the stand research of NO_x emission and PM of an engine equipped with the described fumes recirculation system EGR showing the possibilities of reduction, especially of NO_x in comparison to the standard fumes recirculation system. The use of the suggested solution allows considerable reduction of emission of this component.
