Abstract:

A two cylinder, two cycle engine for an outboard motor includes an alternator driven, capacitor discharge ignition system. The alternator includes an annular permanent magnet secured within a flywheel skirt and includes a pair of circumferential opposite poles with diametrical spaced neutral areas. The magnet is a flexible ferrite strip with a butt joint at one of the neutral areas. A stator assembly is mounted within the annular rotor and includes a semicircular core with a charging coil at each end. Each movement of the magnetic gap means past the coils generates a pulse. A trigger coil within a housing is mounted in coplanar relation between the charging coils, with a pole aligned with and spaced from the stator core. The housing is rotatably mounted and includes an integral cam for positioning a throttle lever. A pair of capacitors are connected in parallel to the charging coils through steering diodes such that the one capacitor is charged from one of the polarity pulses while the other capacitor is charged from opposite polarity pulse.
