Air-fuel ratio feedback control system for internal combustion engine |
摘要 |
<p>A system for estimating air/fuel ratios in individual cylinders of a multicylinder internal combustion engine from an output of an air/fuel ratio sensor installed at an exhaust system of the engine, including: exhaust system behavior deriving means for deriving a behavior of the exhaust system; assuming means for assuming the input as predetermined values; and estimating means for estimating the air/fuel ratios in the individual cylinders from the state variable; whereby engine operating condition detecting means is provided for detecting operating condition of the engine; discriminating means is provided for discriminating whether the detected engine operating condition is in a predetermined region; and said estimating means discontinues to estimate the air/fuel ratios in the individual cylinders when the detected engine operating condition is discriminated to be in the predetermined region.</p> |
