Variable valve operating control apparatus for internal combustion engine and control method thereof |
摘要 |
A centric phase of an operating angle of an engine valve is detected on the basis of an interval between a reference rotational position of a crankshaft and a reference rotational position of a camshaft, and on the other hand, the centric phase is detected each predetermined time, and a Variable valve Timing Control mechanism is feedback-controlled on the basis of a value which has been updated more recently between both detected results.
