PURPOSE:To reduce the number of parts of an engine to get a low cost thereof by installing, inside an engine case, a disc member provided with a plurality of assigned alteration of configuration and a plurality of transducer for generating electric signals corresponding to respective assigned alterations of configuration. CONSTITUTION:Inside an engine case 4, is installed a disc member 27 provided with a plurality of assigned alteration of configuration which turn in synchronism with the rotation of an engine and separate from each other along the circular direction and in the radial direction. A plurality of transducers 35-38 cooperate with the disc member 27 so as to transmit respective electric signals corresponding to respective assigned alteration of configuration. Thus, the whole of an internal-combustion engine can be miniaturized together with less number of parts and low cost. |
