Abstract (en)
[origin: EP2343440A1] An exhaust purification system provided with an exhaust manifold (19), a catalytic converter (21) which is arranged at a downstream side of the exhaust manifold (19) at an angle with respect to the exhaust manifold (19) and which houses an NO X storage and reduction catalyst (20), and a reducing agent feed system (22) which feeds reducing agent into exhaust gas which passes through the inside of the exhaust manifold. The part of the inner wall surface of the casing (30) of the catalytic converter which faces the exhaust manifold outlet is provided with a projecting part (35) which projects out toward the diametrically outward direction of the casing (30). Part of the wall surface which defines the projecting part is formed so that a velocity component, in an axial direction of the casing, of at least part of the flow of exhaust gas which flows into the projecting part, is oriented in an opposite direction to the direction heading toward the NO X storage and reduction catalyst. The exhaust purification system of an internal combustion engine which suppresses an increase in pressure loss of the exhaust gas and causes the reducing agent which was fed from the reducing agent feed system to disperse in the exhaust gas is provided.
