<P>PROBLEM TO BE SOLVED: To provide a fuel injection amount correction control method and a control device, which perform a proper correction control corresponding to a detected error of a sensor in an internal combustion engine. <P>SOLUTION: A diesel engine 100 includes an ECU 40, an airflow meter 42, an exhaust gas temperature sensor 44, an A/F sensor 46 and a rotating speed sensor 48. The ECU 40 calculates the deviation between an actual air-fuel ratio detected with the A/F sensor 46 and a target air-fuel ratio to be decided based on the information from other than the A/F sensor 46 (step S1), to decide whether the deviation is caused by the shift in the amount of fuel injection or not (steps S4, S6, S7). <P>COPYRIGHT: (C)2012,JPO&INPIT |
