Abstract: A particulate filter for trapping the particulate matter which is contained in the exhaust gas is provided inside an engine exhaust passage. Additional fuel is secondarily injected from a fuel injector in an engine expansion stroke or exhaust stroke or hydrocarbons are secondarily added from an addition valve which is provided upstream of the particulate filter in the exhaust pipe. An amount of hydrocarbons which come from the fuel injector or addition valve and then adhere in the form of a liquid to the inflow end of the particulate filter, and an amount of particulate matter which reaches the inflow end of the particulate filter are respectively estimated. A degree of clogging at the inflow end of the particulate filter is estimated based on the amount of hydrocarbons and the amount of particulate matter.

Abstract: In an internal combustion engine, a hydrocarbon feed valve and an exhaust purification catalyst are arranged in an engine exhaust passage. A first NOX removal method which reduces NOX contained in an exhaust gas by a reducing intermediate which is generated by injecting hydrocarbons from the hydrocarbon feed valve within a predetermined range of period and a second NOX removal method in which an air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst is made rich by a period which is longer than this predetermined range are used. The switching temperatures ST and ST0 of the exhaust purification catalyst at which temperature an NOX removal method is switched from the second NOX removal method to the first NOX removal method, are made lower if the amount of NOX in the exhaust gas flowing into the exhaust purification catalyst increases.

Abstract: In an internal combustion engine, a hydrocarbon feed valve and an exhaust purification catalyst are arranged in an engine exhaust passage. A first NOX removal method which injects hydrocarbons from the hydrocarbon feed valve within a predetermined range of period so that the reducing intermediate generated thereby reduces the NOX contained in the exhaust gas and a second NOX removal method which makes the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst a first target rich air-fuel ratio by a period which is longer than this predetermined range are used. When the NOX removal method is switched from the second NOX removal method to the first NOX removal method, the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst is made a second target air-fuel ratio which is smaller than the first target rich air-fuel ratio.

Abstract: An internal combustion engine is provided with a hydrocarbon feed valve arranged in an engine exhaust passage. When injection control for injecting hydrocarbons from the hydrocarbon feed valve for exhaust treatment is stopped, to prevent the hydrocarbon feed valve from clogging, hydrocarbons for preventing clogging are injected from the hydrocarbon feed valve when the engine is not discharging soot, that is, when the feed of fuel to the inside of the combustion chamber is stopped and, after hydrocarbons for preventing clogging are injected once, the injection of hydrocarbons for preventing clogging from the hydrocarbon feed valve is stopped until injection control for exhaust treatment is started.

Abstract: An internal combustion engine in which a hydrocarbon feed valve, exhaust purification catalyst, and NOX selective reduction catalyst are arranged in an engine exhaust passage. A first NOX removal method which injects hydrocarbons from the hydrocarbon feed valve within a predetermined range of period and uses the reducing intermediate which is generated due to this so as to reduce the NOX contained in the exhaust gas and a second NOX removal method which makes the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst rich with a period longer than this predetermined range are used. When the first NOX removal method should be used and the amount of adsorbed ammonia at the NOX selective reduction catalyst is large, use of the first NOX removal method is stopped.

Abstract: During execution of a first purification process of fluctuating a hydrocarbon concentration in exhaust gas flowing into a first catalyst with an amplitude within a prescribed range at a time interval within a prescribed range, when a switch request to a second purification process of purifying NOx in a second catalyst by adding urea water into the exhaust gas is generated, the switch to the second purification process is prohibited on the condition that a current NOx purification rate (a first purification rate R1) is higher than a purification rate (a second purification rate R2) on the assumption that the second purification process is executed, and an HC poisoning recovery stand-by process of reducing an additive amount of hydrocarbon per once in the first purification process is executed so as to reduce a slip amount of hydrocarbon into the downstream of the first catalyst.

Abstract: In an internal combustion engine, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged in an engine exhaust passage. When releasing the stored NOx from the exhaust purification catalyst (13), usually combustion gas of a rich air-fuel ratio is generated in the combustion chamber (2) to make the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) rich. When releasing the stored NOx from the exhaust purification catalyst (13) in case where the temperature of the exhaust purification catalyst (13) is low, the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) is made rich by injecting hydrocarbons from the hydrocarbon feed valve (15).
