ABSTRACT:
A method of controlling the operation of engine valves in an internal combustion engine, dependent on the rotational speed of the engine, by controlling a valve operation changing mechanism capable of opening and closing the engine valves selectively in a low-speed mode of operation corresponding to low-speed operation of the engine and a high-speed mode of operation corresponding to high-speed operation of the engine, the method includes the steps of determining the rotational speed of the engine at which the output torque produced by the engine when the valve operation changing mechanism is in the low-speed mode of operation and the output torque produced by the engine when the valve operation changing mechanism is in the high-speed mode of operation are of a certain relationship to each other and selecting a switching rotational speed for switching operation of the valve operation changing mechanism based on said determined engine rotational speed.
