摘要： An ignition timing control apparatus for an internal combustion engine, when determining that recalculations are possible from the time when final ignition timing is calculated normally to final ignition timing, recalculates the correction amount of the ignition timing by feedback control and the final ignition timing. Accordingly, engine speed at a time closer to actual ignition timing is reflected on the final ignition timing. This configuration prevents overshoot from occurring even when a feedback gain is made greater and thus allows highly-responsive feedback control of the ignition timing thereby suppressing the change in rotation of the engine effectively. When the recalculations are not performed, the final ignition timing based on the correction amount, as normally calculated, is used. Thus, the final ignition timing is maintained at certain accuracy and abnormal ignition such as accidental fire is prevented.

摘要： An ignition timing control apparatus for an internal combustion engine, when determining that recalculations are possible from the time when final ignition timing is calculated normally to final ignition timing, recalculates the correction amount of the ignition timing by feedback control and the final ignition timing. Acccordingly, engine speed at a time closer to actual ignition timing is reflected on the final ignition timing. This configuration prevents overshoot from occurring even when a feedback gain is made greater and thus allows highly-responsive feedback control of the ignition timing thereby suppressing the change in rotation of the engine effectively. When the recalculations are not performed, the final ignition timing based on the correction amount, as normally calculated, is used. Thus, the final ignition timing is maintained at certain accuracy and abnormal ignition such as accidental fire is prevented.

摘要： At the time of startup of an engine having an in-cylinder injector and an intake manifold injector, a risk of pre-ignition during the first-time compression stroke is determined based on a rotational angle of a crankshaft at the time of previous engine stop. When there is a high risk of pre-ignition, fuel injection from the in-cylinder injector having been set to make an air-fuel ratio within the combustion chamber become out of a range enabling combustion (to attain an over-rich condition) is carried out in addition to fuel injection from the intake manifold injector for normal engine startup. Pre-ignition is thus prevented, and smooth engine startup is ensured.

摘要： A compressor drive torque estimating device suppresses a discrepancy between an estimated drive torque, which is based on a torque estimating device of a compressor, and an actual drive torque of the compressor. The discrepancy is due to delay in switching between employment of the torque estimating device and the actual drive torque of the compressor in judging the compressor torque. Thus, even in a transitional state immediately after the start of compression, the idling speed of an engine driving the compressor is controlled based on an accurate estimate of the compressor torque, to improve the stability of the engine idle speed.
