Abstract:
An ignition system for internal combustion engines employing two coordinated power sources which, together, provide a spark of much increased intensity and with extended duration. The first of the coordinated power sources is generally similar to the conventional ignition system employing an ignition coil with a primary and secondary winding, the secondary winding generating a high voltage impulse of very high voltage and low current value and of short duration. The second power source is a storage capacitor which is connected to a direct current power supply which, through a limiting resistor, charges the capacitor to a voltage which is too low to initiate a spark, but high enough to sustain an arc of a controlled high current value for increased duration, once a preliminary spark has been generated across the spark gap at the moment an energizing current in the primary winding of the ignition coil is interrupted. The two coordinated power sources may be connected to the spark plug in parallel connection through rectifiers, which provide separation between the power sources, or the two power sources may be connected with the spark plug in series connection again using rectifiers to separate them. Multiple sequentially firing spark plugs as used in engines with multiple cylinders may be driven by the present invention by incorporating a distributor which sequentially distributes either the preliminary spark or the combined sparking energy to the spark plugs.
