摘要： A method for operating an internal combustion engine includes the step of measuring emission values of at least two pollutant components of an exhaust gas of an internal combustion engine. A value of at least one operating parameter of the internal combustion engine is changed in order to decrease an emission value of a first pollutant component if the emission value of the first pollutant component exceeds a given maximum threshold value. An emission value of a second pollutant component is monitored in order to determine whether the emission value of the second pollutant component remains below a maximum value for the second pollutant component and whether an increase in the emission value to the maximum value for the second pollutant component is permitted.

摘要： An air fuel ratio control apparatus readily satisfies an emission requirement and is particularly preferable for small-displacement engines. The air fuel ratio control apparatus for an engine includes a fuel control member disposed in a fuel passage delivering fuel from a fuel metering chamber of a carburetor supplying the fuel to a suction passage of a comparatively small engine such as a general purpose engine, a working machine engine and the like, a combustion gas sensor disposed in an exhaust pipe in the engine, and an electronic control unit. The control unit actuates the fuel control member in response to a concentration of a combustion gas component in an exhaust gas detected by the combustion gas sensor so as to control a fuel flow rate.

摘要： A method is disclosed for controlling operation of an engine coupled to an exhaust treatment catalyst. Under predetermined conditions, the method operates an engine with a first group of cylinders combusting a lean air/fuel mixture and a second group of cylinders pumping air only (i.e., without fuel injection). In addition, the engine control method also provides the following features in combination with the above-described split air/lean mode: idle speed control, sensor diagnostics, air/fuel ratio control, adaptive learning, fuel vapor purging, catalyst temperature estimation, default operation, and exhaust gas and emission control device temperature control. In addition, the engine control method also changes to combusting in all cylinders under preselected operating conditions such as fuel vapor purging, manifold vacuum control, and purging of stored oxidants in an emission control device.

摘要： An air-fuel ratio control device switches a target air-fuel ratio from a lean set air-fuel ratio to a rich set air-fuel ratio after judging that an air-fuel ratio of an outflowing exhaust gas has become a stoichiometric air-fuel ratio and an oxygen storage amount of an exhaust purification catalyst has become a switching reference storage amount, and makes an average value of the target air-fuel ratio the stoichiometric air-fuel ratio to less than the lean set air-fuel ratio, from after the estimated value of the oxygen storage amount has become the switching reference storage amount or more until judging that the air-fuel ratio of the outflowing exhaust gas has become the stoichiometric air-fuel ratio if the estimated value of the oxygen storage amount becomes the switching reference storage amount or more before judging that the air-fuel ratio of the outflowing exhaust gas has become the stoichiometric air-fuel ratio.
