An electromagnetically driven valve control system for an internal combustion engine having at least one intake valve and at least one exhaust valve, and a starter for starting cranking of the engine. A CPU controls an energization time/timing control circuit section to electromagnetically drive at least one of the at least one intake valve and the at least one exhaust valve. The CPU detects a starting signal indicative of starting of the cranking of the engine, and a timer measures a time period elapsed after the starting signal is detected. An inhibiting time period is set, over which the operation of the starter means is inhibited, and the at least one of the at least one intake valve and the at least one exhaust valve is driven in a valve closing direction when the starting signal is detected. The operation of the starter is permitted when the time period elapsed after the starting signal is detected exceeds the inhibiting time period.

An electromagnetically driven valve control system for an internal combustion engine having a combustion cylinder with a valve, comprising: electromagnetic driving means for electromagnetically driving said valve; starting signal-detecting means for detecting a starting signal indicative of a command for starting cranking of the engine; valve-closing control means responsive to detection of said starting signal for driving said valve in a valve closing direction; and control means for delaying said starting cranking of the engine until said valve is closed in response to said valve-closing control means. An electromagnetically driven valve control system for an internal combustion engine having a combustion cylinder with a valve, comprising: electromagnetic driving means for electromagnetically driving said valve; control means for delivering a control signal to said electromagnetic driving means to control same; starting signal-detecting means for detecting a signal indicative of a command to start cranking the engine; stoppage signal-detecting means for detecting a signal indicative of a command to stop the engine; said control means responsive to detection of said signal for starting cranking and said signal to stop the engine for driving said valve in a valve closing direction in response to each said signal; and said control means including means for maintaining said valve in a closed position after responding to each said signal for a period that avoids interference between said valve and a piston in the combustion cylinder during the starting of cranking and the stopping of the engine.
