Abstract

There is provided a valve timing varying mechanism (VTC) to vary a valve timing. An estimated VTC conversion angle VTCNFS is calculated in accordance with a sensed VTC conversion angle VTCNOW (S 15 ˜S 19 ). At the time of conversion of the VTC conversion angle to the advance side or retard side, a fastest response value is calculated by conversion of the VTC conversion angle from the previous sensed value with a fastest response speed, and the sensed value (estimated value) is limited to or below the fastest response value when the current value of the sensed valve timing exceeds the fastest response value (S 20 , S 21 ).

First claim

The invention claimed is:

1. An engine control apparatus for an internal combustion engine provided with a valve timing varying mechanism to vary a valve timing of an intake valve of the internal combustion engine, the engine control apparatus comprising:
a sensing section to detect a value of a sensed valve timing of the intake valve;
an ignition timing controlling section to control an ignition timing of the internal combustion engine in accordance with the sensed valve timing…
