摘要：A control system for an internal combustion engine having a plurality ofcylinders each having at least one intake valve, at least one exhaust valve, and acrankshaft. The control system has an electromagnetic driving section which

electromagnetically causes opening and closing of at least one of the at least one intakevalve and the at least one exhaust valve. A crank angle sensor generates a crank anglesignal whenever the crankshaft rotates through a predetermined angle, and a cylinderposition sensor generates a cylinder-discriminating signal indicative of a predeterminedcrank angle of a particular cylinder of a plurality of the cylinders. A piston position sensordetects an operating state or position of the piston of each of the plurality of thecylinders, based on the generated crank angle signal and the generated cylinder-discriminating signal. A CPU starts opening of the at least one of the at least one intakevalve and the at least one exhaust valve, based on the detected operating state of thepiston.
