摘要： 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.

摘要： In a failure diagnosis device of an emission control system that utilizes an electrode-based PM sensor provided downstream of a particulate filter in an exhaust conduit to diagnose a failure of the particulate filter, disclosed embodiments may suppress reduction of accuracy of diagnosis of a failure due to in-cylinder rich control. The failure diagnosis device of the emission control system starts application of a predetermined voltage to electrodes of the electrode-based PM sensor after a sensor recovery process that removes PM depositing between the electrodes of the PM sensor, and diagnoses a failure of the particulate filter based on an output of the PM sensor measured after elapse of a predetermined time period since the start of application of the predetermined voltage. The failure diagnosis device performs the sensor recovery process during in-cylinder rich control or triggered by termination of the in-cylinder rich control and subsequently performs a measurement process after termination of the in-cylinder rich control and the sensor recovery process.

摘要： An object of the present invention is to detect an abnormality in an exhaust gas purification apparatus having an NSR catalyst and an SCR catalyst disposed on a downstream side of the NSR catalyst more favorably. Air-fuel ratio reduction control is executed to reduce NOx occluded to the NSR catalyst when an integrated value of an amount of NOx flowing into the NSR catalyst reaches an upper limit value of an amount of NOx that can be occluded to the NSR catalyst in a normal condition. It is determined whether or not the exhaust gas purification apparatus is in an abnormal state on the basis of a NOx purification ratio of the exhaust gas purification apparatus calculated at this time.

摘要： An internal combustion engine comprises a hydrocarbon feed valve (15) arranged in an engine exhaust passage and a booster pump (60) for boosting an injection pressure of the hydrocarbon feed valve (15). The hydrocarbon feed valve (15) performs NOX removal injection and clogging prevention injection. A boosting action of the injection pressure by the booster pump (60) and the NOX removal injection are controlled so that the boosting action of the injection pressure by the booster pump (60) and the NOX removal injection are not performed simultaneously, and the boosting action of the injection pressure by the booster pump (60) and said clogging prevention injection are allowed to be performed simultaneously.
