摘要： In a valve timing control apparatus configured to execute phase-control via a phase converter, a controller is configured to control a phase angle of a camshaft relative to a crankshaft during an engine stopping period to a target phase angle differing from a required phase angle suited for an engine operating condition. The controller is further configured to change the phase angle of the camshaft toward the required phase angle during a time period from a point of time when cranking starts to a point of time when detection of a rotational position of the camshaft initiates during an engine restarting period. The controller is still further configured to start feedback-control for the phase angle of the camshaft from the point of time of initiation of detection of the rotational position of the camshaft for bringing the phase angle of the camshaft closer to the required phase angle.

摘要： A misfire detector detects a misfire in a cylinder based on a maximum value and the minimum value of the angular speed. A first crank angle range is defined in such a manner as to include a crank angle in which the angular speed is maximum during a power stroke. A second crank angle range is defined in such a manner as to include a crank angle in which the angular speed is minimum during the power stroke. The maximum value of the angular speed is calculated within the first crank angle range, and the minimum value of the angular speed is calculated within the second crank angle range. The calculated maximum and minimum values are brought close to actual values to enhance a reliability of the misfire detector.

摘要： A memory stores and holds both the number of crankshaft angle pulse signals occurring after detecting a reference portion when an engine stops and data relating to whether the reference portion which is supposed to be next detected upon re-start of the engine is a reference position of the camshaft. When the engine is re-started, it is determined whether a reverse rotation of the crankshaft across the reference position happened by comparing a predetermined value with the total obtained by adding the number of pulse signals stored in the memory and the number of pulse signals occurring until the reference portion is first detected again. When such reverse rotation happened, the reference position of the camshaft is shifted by 360.degree. CA. Therefore, regardless of whether such reverse rotation across the reference position happened or not, the engine timing cycle is again precisely synchronized.
