An exhaust gas treating system for a gasoline engine, comprising an exhaust gas manifold comprising an annular reforming catalyst mounted within an annular housing and fuel supply means in direct fluid connection with the catalyst, an outlet for reformed fuel products in direct fluid connection with the catalyst, and means to permit a proportion of the engine-out exhaust gases to enter the annular catalyst to mix with fuel from the fuel supply means and to pass through the catalyst, the annular housing being located such that hot engine-out exhaust gases can flow around and through the center of the housing, such that heat is transferred from the exhaust gases to the catalyst within the housing. The reformate may be passed to the inlet side of the engine, to improve overall efficiency of the engine, and/or may be mixed with exhaust gas before catalytic aftertreatment, to improve the control of emissions. |
