摘要： A moisture adsorbent (32) for adsorbing moisture in exhaust gas and an NOx adsorbent (34) for adsorbing NOx are disposed in a bypass passage (30) for bypassing an exhaust passage (16) of an internal combustion engine (10). When an adsorption operation to the NOx adsorbent (34) is executed, inflow of the exhaust gas to the bypass passage (30) is allowed until the moisture amount that flows into the water adsorbent (32) reaches an allowable moisture inflow amount. The allowable moisture inflow amount is determined based on a residual moisture amount before the starting of the adsorption operation in the moisture adsorbent (32). The residual moisture amount in the water adsorbent (32) can be determined based on the temperature of the moisture adsorbent (32) at the immediately preceding execution of the purge operation.

摘要： A control apparatus for an internal combustion engine is provided, which is capable of suppressing deterioration of exhaust emission due to an unburned fuel contained in oil which enters a combustion chamber during valve stop control while preventing inflow of fresh air to a catalyst, at a time of valve return following return from fuel cut. Variable valve operating apparatuses (34, 36) having valve stop mechanisms capable of changing operation states of an intake valve (30) and an exhaust valve (32) between valve operation states and valve closed and stopped states are included. Valve stop control that changes the operation states of the intake valve (30) and the exhaust valve (32) to the valve closed and stopped states is performed, at a time of execution of the fuel cut. When a return request from the fuel cut with the valve stop control is detected, a fuel is supplied to a combustion chamber (14) before the operation state of the exhaust valve (32) is returned to the valve operation state. The fuel supply amount in this case is corrected in accordance with an amount of the unburned fuel contained in the oil which enters into the combustion chamber (14) from a crank chamber (16) side during the fuel cut with the valve stop control.

摘要： When, for example, a predetermined operating condition such as a fuel cut operating condition is satisfied (time-point tfc), an air-fuel ratio imbalance among cylinder determining apparatus sequentially stops a fuel injection for each of cylinders in accordance with a firing (ignition) order, and changes intake valves and exhaust valves of the cylinder whose fuel injection is stopped from a valve operating state to a valve resting state. Consequently, after a time-point at which an exhaust gas (final gas) is discharged from a cylinder into an exhaust passage (the exhaust gas being generated from a fuel injected lastly for that cylinder), no new gas is discharged from that cylinder. Accordingly, when a predetermined time elapses (time-point tp), an upstream-side air-fuel ratio abyfs obtained based on an output value of an upstream air-fuel ratio sensor disposed in the exhaust passage becomes a value corresponding to an air-fuel ratio of the final gas. The determining apparatus obtains that value as data relating to an air-fuel ratio of the cylinder which discharged the final gas, and determines whether or not an air-fuel ratio imbalance is occurring based on the data relating to the air-fuel ratio of each of the cylinders.

摘要： A moisture adsorbing device 1 comprising a type Y zeolite, and an NO x adsorbing device 2 being put in place on an exhaust-gas downstream side of the moisture adsorbing device 1, and comprising a zeolite that includes a transition metal ion in the cation exchange sites are included. In NO x adsorbing apparatuses, since the less the moisture content in exhaust gases is the more the NO x adsorbing capability improves, the NO x adsorbing capability in low-temperature region is improved especially by means of the combination with a moisture adsorbing device that comprises a type Y zeolite whose Al 2 O 3 proportion is great and whose moisture adsorbing amount is great compared with the other zeolites.
