Abstract: PURPOSE: A method and an apparatus for controlling continuously variable valve timing are provided to achieve improved accuracy of valve timing control by controlling the valve timing to the target timing in a rapid manner. CONSTITUTION: A method comprises a first step(S310) of determining a target timing for a valve timing; a second step(S315,S320) of changing the current duty ratio of the actuator for changing valve timing, by the learned initial displacement; and a third step(S325 to S335) of gradually changing the duty ratio of the actuator until the valve timing has reached the target timing. The third step includes a first sub-step of detecting a valve timing; a second sub-step of judging whether the detected valve timing corresponds to the target timing; and a third sub-step of changing the duty ratio of the actuator when the valve timing does not correspond to the target timing.

Abstract: An apparatus for, and a method of, purifying exhaust gas emitted from an internal combustion engine reduces fuel consumption under a lean operating condition and generates high torque under a rich operating condition without deteriorating the cleanness of exhaust gas and the driveability of the engine. The apparatus and method improve the durability of a variable valve timing mechanism of the engine. The engine operation involves lean and rich operating conditions. The variable valve timing mechanism (92) of the apparatus changes the open and close timing of at least one of intake valve (24) and exhaust valve (26) of the engine. The apparatus further has a catalytic converter (38) in an exhaust system, to occlude NOx under the lean operating condition and discharge and reduce the occluded NOx under the rich operating condition. The apparatus also has a prohibition unit (70) for prohibiting the variable valve timing mechanism (92) from changing the valve open and close timing of the valves when the air-fuel ratio of the engine is changed from lean to rich to discharge and reduce the occluded NOx.
