4-CYCLE ENGINE

摘要

A 4-cycle engine comprises a detection magnetic member mounted on a cam pulley of a non-magnetic material which is rotated in operative association with a crank pulley, for detecting a plurality of detection portions formed on said detection magnetic member by coils mounted in a cylinder head. The detection magnetic member is integrally formed with the plurality of detection portions for different uses in such a manner that distances from the center rotation of the cam pulley to the plurality of detection portions are different. The coils are separately mounted in correspondence to the detection portions. Thus timing signals for different uses can be derived from the single cam pulley.
