摘要： An exhaust emission control device for an internal combustion engine, which is capable of supplying a just enough amount of reducing agent to the NOx catalyst even when a catalyst is provided on an upstream side of the NOx catalyst. A catalyst and a NOx catalyst are disposed at respective upstream and downstream locations in an exhaust system, for purifying NOx and for trapping NOx under an oxidizing atmosphere and reducing the NOx under a reducing atmosphere, respectively. An air-fuel sensor is disposed between the catalyst and the NOx catalyst. A reducing agent is supplied to an upstream side of the catalyst, to control exhaust gases such that the gases form the reducing atmosphere. To determine time of termination of NOx reduction control, an amount of reducing agent supplied to the NOx catalyst is calculated, and calculation of the amount of reducing agent is started when the air-fuel ratio has converged within a vicinity of a target air-fuel ratio.

摘要： Provided is a control device for an internal combustion engine that can execute a sulfur purge in a favorable manner under all conditions without complicating the control action or the engine structure. The process comprises detecting a temperature of the NOx catalytic converter, detecting an exhaust air fuel ratio in the catalytic converter, computing a target exhaust air fuel ratio according to a detected temperature of the NOx catalytic converter, and controlling a fuel injection valve so as to make an actual exhaust fuel ratio agree with the target exhaust air fuel ratio. If the temperature of the NOx catalytic converter is not high enough to enable a sulfur purge, a temperature increase control is executed to increase the temperature of the NOx catalytic converter by suitably changing various engine parameters.

The exhaust purification device has a NOx purification catalyst (33) mounted in an exhaust pipe (4) of the internal combustion engine, adsorbing or occluding NOx in exhaust gas when the exhaust gas air/fuel ratio is made lean, and reducing the adsorbed or occluded NOx when the exhaust gas air/fuel ratio is made rich; a fuel reformer (50) mounted separately from the exhaust pipe (4), reforming fuel to produce a reducing gas containing hydrogen and carbon monoxide, and supplying the reducing gas into that part of the exhaust pipe (4) which is located upstream of the NOx purification catalyst (33); and enriching means for enriching the exhaust gas air/fuel ratio. When one or more of operating conditions are satisfied, the enriching means enriches the air/fuel ratio of mixed gas to be combusted in the engine and causes the fuel reformer (50) to supply the reducing gas into the exhaust pipe (4) to enrich the exhaust gas air/fuel ratio.

摘要： A control system for an internal combustion engine, which is capable of properly setting fuel injection timing according to the actual degree of delay of the amount of fresh air to be supplied to cylinders of the engine, thereby making it possible to positively suppress torque variation, when the control system has switched an air-fuel ratio mode between a lean mode and a rich mode. The control system controls the air-fuel ratio of a mixture by switching the air-fuel ratio mode. In the lean mode, the control system sets a target fresh air amount for the lean mode, and in the rich mode, it sets a target fresh air amount for the rich mode. Upon switching the air-fuel ratio mode, the control system corrects the fuel injection timing according to the difference between the target fresh air amount for the lean mode or the rich mode and the detected fresh air amount.

摘要： An exhaust emission control device for an internal combustion engine, which is capable of properly regenerating a NOx catalyst, while properly controlling NOx catalyst temperature and ensuring excellent drivability. As a regeneration operation, the exhaust emission control device feedback-controls a detected reducing condition of exhaust gases to a predetermined reducing condition, by controlling the amount of main fuel injected by main injection or feedback-controls the same to the predetermined reducing condition by controlling the amount of auxiliary fuel injected by auxiliary injection. The device determines whether the regeneration operation should be executed in a catalyst temperature control mode for controlling the NOx catalyst temperature. If, as a result of the determination, the regeneration operation should be executed in the catalyst temperature control mode, the device selects the feedback control of the main fuel amount, and otherwise selects the feedback control of the auxiliary fuel amount.
