A crank angle sensor for a multicultural internal combustion engine and a cylinder identification system utilizing the same. The crank angle sensor has a rotor provided with ((number of cylinder/2)+1)) number of projections (markers) at reference positions corresponding to predetermined piston positions of the individual cylinders and two electromagnetic pickups spaced apart by twice the interval between adjacent reference positions. The cylinder is identified by comparing the two output pulse trains of the electromagnetic pickups over two reference positions.
