    Abstract: In an exhaust gas pipe, a first fluid flows in a flow direction in the pipe, and a second fluid is injected inside the pipe by a nozzle, from an injection inlet arranged in the pipe wall, according to an injection direction. A mixing device fastened inside the pipe upstream from the injection inlet creates turbulence that helps the mixing of the fluids. The mixing device has a first portion located on the injection inlet side of the pipe and a second portion located opposite the injection inlet side of the pipe, the portions being designed so that the fluid velocity is higher downstream from the mixing device second portion than downstream from the mixing device first portion. An aqueous solution of urea can be injected inside an exhaust pipe of a diesel engine.

    Abstract: In an internal combustion engine, inside an engine exhaust passage, a hydrocarbon feed valve (15) an exhaust purification catalyst (13), and a particulate filter (14) are arranged. If the hydrocarbon feed valve (15) feeds hydrocarbons by a period of within 5 seconds, a reducing intermediate is produced inside the exhaust purification catalyst (13). This reducing intermediate is used for NOx purification processing. When the stored SOx should be released from the exhaust purification catalyst (13), the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) is made rich, the reducing intermediate built up on the exhaust purification catalyst (13) is made to be desorbed in the form of ammonia, and the desorbed ammonia is used to make the exhaust purification catalyst (13) release the stored SOx.

    Abstract: In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. On the exhaust purification catalyst (13), platinum Pt (51) is carried and a basic layer (53) is formed. At the time of engine operation, a main concentration changing action in which the concentration of hydrocarbons which flow into the exhaust purification catalyst (13) is made to change by a predetermined amplitude (ΔHA) and predetermined period (ΔTA) is performed. Furthermore, before each main concentration changing action, an auxiliary concentration changing action in which the concentration of hydrocarbons is made to change by an amplitude (ΔHB) smaller than the amplitude (ΔHA) at the time of each main concentration changing action is performed.
