出機構。The rotor plate, which rotates together with the crankshaft of the high-twist engine, is provided with slits for crank angle detection at regular angular intervals in the circumferential direction, and the slits are arranged on the same circumference as the slits. A reflective part for cylinder detection is provided on the plate surface at a position that does not overlap with the plate surface, and a light emitting element is placed on one side of the plate and a first light receiving element is placed on the other side, so that the light emitted from the light emitting element and the plate The light passing through the slit is detected by the first light-receiving element, and a second light-receiving element is installed on the same side of the plate as the light-emitting element, and the light emitted from the light-emitting element and reflected by the reflective part of the plate is A crank angle detection mechanism for an internal combustion engine that detects
