    • Provided is an exhaust purification device for an internal combustion engine, wherein the operation of an internal combustion engine can be prevented from being maintained when a particulate filter is melted. An exhaust purification device (1) for an internal combustion engine (2) is comprised of a particulate filter (10); a downstream-side temperature sensor (20a) which detects a downstream-side exhaust temperature (T1); a filter temperature sensor (20b) which detects a filter temperature (T10); an exhaust differential pressure detection device (21) which calculates an exhaust differential pressure (P(n)) between an upstream-side exhaust pressure (p1) and a downstream-side exhaust pressure (p2) at predetermined time intervals; a notification device (40); and an ECU (30) which controls the internal combustion engine (2). In the exhaust purification device (1), a differential pressure variation (dP) is calculated on the basis of a first exhaust differential pressure (P(n-1)) and a second exhaust differential pressure (P(n)) after the elapse of a predetermined period of time. When the differential pressure variation (dP) is equal to or larger than a reference variation (Ps) or the downstream-side exhaust temperature (T1) remains equal to or larger than an exhaust reference temperature (T1s) for a period of time equal to or longer than a reference period of time (ts), a demand to stop operating the internal combustion engine (2) is notified, or the operation is stopped.

    • Disclosed is a control device applied to an internal combustion engine provided with a fuel vapor treatment system for treating collected fuel vapor by purging the collected fuel vapor into intake air downstream from an air flowmeter (6) and an exhaust gas recirculation system for recirculating part of exhaust gas in the intake air using intake negative pressure. An electronic control unit (22) performs an advance correction corresponding to the exhaust gas recirculation quantity regarding the MBT ignition timing and the knock limit ignition timing, and corrects the volumetric efficiency of the internal combustion engine, which is used for the calculation of the advance correction quantity used for the advance correction, according to the purge air quantity. Consequently, regardless of the decrease of the exhaust gas recirculation quantity caused by the implementation of a large quantity of purge, the appropriate advance corrections of the MBT ignition timing and the knock limit ignition timing become possible.
