The invention relates to a thermally, and optionally catalytically, operative exhaust gas treatment reactor of an engine, comprising filamentary material directly against and inside the heat insulating portion of a housing assembly which is placed on an engine over the exhaust ports, either directly or with a member interposed. Rapid warm up during cold start is achieved by restriction of gas flow, with the optional re-routing of exhaust gas, including routing to a reservoir which may be expansible. Other features include various embodiments of filamentary material, mechanism for accurately regulating exhaust gas recirculation and provision of extra air, the providing a secondary substance such as water/methanol or steam to induction charge to assist in the balancing of exhaust reactions. Treatment of exhaust gas is generally but not specifically to remove certain undesired pollutants from the exhaust gas of vehicles as required in many countries.
An internal combustion engine comprising a cylinder block having an external face, said block having at least one exhaust port in said face and at least one intake port, and a housing which when fitted over said at least one exhaust port defines together with the face of said block an exhaust gas reaction volume and an exit, whereby gas proceeds directly from the exhaust port into and through the volume to said exit provided in the housing without reversal of direction, said housing in cross-section parallel to the face of said block being roughly elliptical.
An internal combustion engine exhaust gas reaction volume housing suitable for mounting directly against an engine block, said housing having a first aperture for gas exit and a second aperture for gas entry, said second aperture being larger than said first aperture, said second aperture defining a perimeter suitable for mounting against a portion of the surface of an engine block having at least two exhaust ports, in operation gases passing between the apertures without reversal of direction.
A housing for enclosing a combustion engine exhaust gas reaction volume, said housing having single gas entry means and at least one gas exit means opposite said entry means, said housing mountable over at least one exhaust port set in an engine block surface, the cross-sectional area of said reaction volume at said entry means being substantially greater than the cross-sectional area of said port, so that in operation a substantial body of exhaust gas will, during travel from within said port to within said volume, decrease its forward velocity and increase its cross-sectional area, said body travelling from within said exhaust port to said exit means without reversal of direction, the interior surface of said housing at any cross-section taken at an angle to said block surface through a continuous surface of said housing resembling a bent line with two ends, said ends representing the perimeter of said entry means.
An internal combustion engine having a block with a plurality of exhaust ports, an exhaust gas reaction volume housing having a first aperture for gas exit and a second aperture for gas entry, an intermember suitable for mounting between the perimeter of said second aperture and a surface of said block having said exhaust ports, the contact area between said intermember and said block having a single external perimeter.
