Abstract
An engine rotational position detector and distributor assembly has a crank-driven rotary member mounted on an end portion of a cam shaft extending outwardly from engine block. The end face of the rotary member is formed therein with an annular recess and has a reference position information projection on the radially inner peripheral wall of the recess and a plurality of angular position information projections on the radially outer peripheral wall of the recess. The rotary member is covered with a detector housing mounted on the engine block and having an outer end wall supporting sensors faced to the circular paths of circumferential movements of the projections on the rotary member. The detector housing end wall has central opening with a bearing mounted therein to receive the outer end portion of the cam shaft and position the detector housing relative to the cam shaft whereby the sensors are precisely positioned relative to the circular paths of the movements of the projections. The cam shaft terminates in an outer end extremity on which a distributor rotor is mounted and covered with a distributor cap mounted on the detector housing.
