    • PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine which can calculate an amount of air passing through a throttle valve more accurately.
      SOLUTION: The controller of the internal combustion engine includes an air intake passage, and the throttle valve 18 for regulating a flow rate of the air passing through the air intake passage.

    • PROBLEM TO BE SOLVED: To maintain accuracy of feedback control even if atmospheric air leak occurs in an exhaust gas sensor in relation to an exhaust emission control device used for an internal combustion engine provided with the exhaust gas sensor in a downstream of catalyst. SOLUTION: Feedback control of fuel injection quantity is performed based on output value of a sub O 2 sensor arranged in the downstream of the catalyst and a control target value of the output value. Air fuel ratio in an upstream of the catalyst is reversed from lean air fuel ratio to rich air fuel ratio (step 102) under a condition where the sub O 2 sensor outputs lean output (step 100). Output of the sub O 2 sensor is detected as a stoichiometric output during stoichiometric gas is flowing out to the downstream of the catalyst after reversal of air fuel ratio (step 104). The control target value is corrected to make the stoichiometric output close to a reference value (step 106). COPYRIGHT: (C)2005,JPO&NCIPI
