Abstract
An apparatus for detecting crank angle position in an internal combustion engine, in which a first rotator, which is interlocked with the crankshaft, has a plurality of detectable parts in the rotation direction, the detectable parts on the first rotator are provided so that adjoining spaces are nearly equal to each other. A second rotator which is interlocked with the camshaft has a plurality of detectable parts in the rotation direction, the detectable parts on the second rotator are provided so that permutations each consisting of at least two of consecutive angle intervals in one rotation direction differ from each other. With this configuration, the stroke of an internal combustion engine can be determined in a short time.
