Abstract: An exhaust gas catalyst system for a vehicle, for treating fine dusts of exhaust gases produced by an internal combustion engine group of the vehicle, having an inlet duct and an outlet duct connectable to the internal combustion engine group and to a diesel particulate filter (DPF) system. A hollow main body extends along a main axis (X-X) between a head wall having an inlet opening and an outlet opening, and a bottom wall and defines a gas treatment chamber having a first chamber fluidically connected to the inlet opening and a second chamber fluidically connected to the outlet opening. The first and second chambers are fluidically connected in a region proximal to the bottom wall so exhaust gases flow in the first and second chambers in opposite directions. Exothermic filtration and oxidation operations are carried out on the fine dusts by a catalyst substrate housed in the second chamber.

Abstract: The invention describes an internal combustion engine (14) for a vehicle (12) that comprises a fly-wheel (24) placed at the rear part with respect to the internal combustion engine (14), a cooling system (28) placed at the front part with respect to the internal combustion engine, a forced induction group consisting of a turbine (22), placed on the same side as the fly-wheel (24), and a compressor (30), placed on the same side as the cooling system (28), and a system (10) for treating the exhaust gases provided with a conduit for the inlet of exhaust gases, operatively connected to the exit door of the turbine, a conduit for the outlet of exhaust gases and a main body or shell (38) internally hollow for containing a substrate (44) through which the exhaust gases are conveyed so that they are subject to predefined chemical reactions.
