CONDENSER DISCHARGE IGNITION SYSTEM WITHOUT BREAKER BY SYNCHRONOUS GENERATOR DRIVING WITH IMPROVED SLOW TIMING CHARACTERISTICS

Japanese Patent JPS56159560

A

An alternator-powered breakerless capacitor discharge ignition system for an alternate firing two-cylinder outboard motor provides improved timing characteristics at low, as well as high, engine speeds and prevents reverse engine rotation. The alternator rotor and stator assemblies define a first magnetic circuit which provides constant polarity, constant power pulses for charging a single capacitor in the system. The alternator rotor and trigger assemblies define a second magnetic circuit which provides synchronized narrow trigger pulses, successive one's being of opposite polarity, to operate an electronic control circuit to effect timed capacitor discharge to a pair of spark plug ignition coils in the system. The first magnetic circuit includes a pair of relatively narrow ceramic permanent magnets spaced 180 DEG apart on the alternator rotor flywheel for energizing series-connected, oppositely wound, spaced apart low-speed and high speed stationary windings in the stator assembly. The second magnetic circuit includes a two-pole magnetic strip on the flywheel hub for energizing an adjustably positionable (advance/retard) specially designed trigger coil in the trigger assembly. The low speed winding, the capacitor, and the ignition coils each have one side grounded to reduce system wiring complexity and cost.
