    • An engine controlling apparatus is provided in which a stable limp-home drive is possible even if an open breakdown of a throttle valve occurs. The apparatus includes a throttle breakdown detecting unit S1 for detecting the breakdown in a throttle controlling system including the throttle valve and a throttle opening degree sensor, a throttle power source interrupting unit S2 for interrupting a power source supply to a throttle actuator in the case where the breakdown in the throttle controlling system is detected, and a predetermined operational condition detecting unit S3 for detecting a shift of the operational condition to a predetermined operational condition corresponding to a fully closed condition of the throttle valve in operation of the throttle power source interrupting unit. A bypass controlling unit S4 opens the bypass valve to feed the air to the engine at the time when the predetermined operational condition is detected in operation of the throttle power source interrupting unit.

    • An internal combustion engine control apparatus can reliably detect abnormality in a crank angle position signal to ensure a fail safe function upon occurrence of the abnormally. A fuel injection signal and an ignition signal is generated based on the result of cylinder identification performed by a cylinder identification part and the crank angle position of the crank angle position signal. An abnormality determination part determines whether the crank angle position signal is abnormal. The cylinder identification part includes a cylinder identification resetting part for resetting the current content of the cylinder identification performed by the cylinder identification part upon determination of abnormality. The cylinder identification resetting part includes a fuel injection and ignition signal stopping part for stopping the fuel injection signal and the ignition signal, and a cylinder identification information clearing part for clearing previous cylinder identification information earlier than the last crank angle position signal upon determination of abnormality.

    • A valve timing control system for an internal combustion engine, comprising a required advance amount calculating section for calculating a required advance amount on the basis of operating condition of the engine, a valve timing control section for calculating a valve timing control variable on the basis of an obtained advance amount and the required advance amount calculated by the required advance amount calculating section, and a time period measuring section for measuring an elapsed time after the start of the engine. The required advance amount calculating section makes a calculation so that the required advance amount assumes a value smaller than that in an normal state until the time period measuring section measures a predetermined period of time. Hence, exhaust gas clarification immediately after the engine start, fuel consumption and drivability can be improved.
