BREAKERLESS IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

In a distributor device for an internal combustion engine having spark plug means for initiating combustion, an ignition signal generating unit for supplying the ignition pulses to the plug means comprising a first plate having at least one electrically conductive surface, a second plate rotatably supported with respect to the first plate with a predetermined gap therebetween for allowing a capacitive action to take place between the plates, the second plate having a configuration permitting variation of the capacitive effect between a maximum and a minimum value, whereby an input voltage to the unit is amplitude modulated as an output voltage.
