    摘要： An air-fuel control system for use with an internal combustion engine has a catalytic converter disposed in an exhaust system of the engine, for purifying an exhaust gas emitted from the engine, a first exhaust gas sensor in the exhaust system for detecting an air-fuel ratio of the exhaust gas upstream of the catalytic converter, a second exhaust gas sensor in the exhaust system for detecting the concentration of a component of the exhaust gas which has passed through the catalytic converter, downstream of the catalytic converter, and a correction quantity calculator for determining a correction quantity to correct an air-fuel ratio of the engine based on an output from the second exhaust gas sensor so as to equalize the concentration of the component of the exhaust gas downstream of the catalytic converter to a predetermined appropriate value. The air-fuel ratio of the engine is controlled based on the determined correction quantity and an output from the first exhaust gas sensor so as to converge the concentration of the component toward the predetermined appropriate value. A state predictor estimates the concentration of the component, detected by the second exhaust gas sensor, after a dead time present in an exhaust system including the catalytic converter between the first and second exhaust gas sensors, based on outputs up to present from the first and second exhaust gas sensors. The correction quantity calculator determines the air-fuel ratio of the engine so as to equalize the concentration of the component to the predetermined appropriate value, based on the estimated concentration of the component.

    摘要： A system for purifying exhaust gas generated by an internal combustion engine including a bypass branching out from the exhaust pipe downstream of a catalyst and merging to the exhaust pipe, an adsorber installed in the bypass, a bypass valve member which closes the bypass, and an EGR conduit connected to the bypass at one end and connected to the air intake system for recirculating the exhaust gas to the air intake system. The bypass valve member is opened for a period after engine startup to introduce the exhaust gas such that the adsorber installed in the bypass adsorbs the unburnt HC component in the exhaust gas. The adsorber adsorbs the HC component when the exhaust temperature rises and the adsorbed component is recirculated to the air intake system through the EGR conduit. In the system, the bypass valve is provided at or close to the branching point in the exhaust pipe and a chamber is provided close to the branching point such that the conduit is connected to the bypass at the one end in the chamber. The bypass valve member is combined with an exhaust pipe valve member as a combination valve such that when the bypass valve member closes the bypass, the exhaust pipe valve member opens the exhaust pipe. With the arrangement, the system can effectively prevent the exhaust pipe from being clogged even when a valve for closing a bypass is stuck in the closed position. At the same time, the system can provide a relatively short EGR conduit for recirculating unburnt HC component adsorbed from the adsorber and the adsorption and desorption are conducted optimally.
