Control device for internal combustion engine controls valve timing mechanism so that advance becomes target value

摘要

The control device includes an engine operating condition detector (1), a crank angle detector, a variable valve-timing mechanism (7) for the inlet and outlet valves, and a detector for determining the actual valve control time position for each crank angle position. A control unit (6) controls the valve timing mechanism so that the advance becomes a target advance set by a setting unit. The deviation between the target advance and the actual advance is determined for each crank angle position.
