ABSTRACT:
An apparatus for producing spark ignition of an internal combustion engine is disclosed including a spark generator which supplies spark generating pulses to spark plugs of the engine. The spark produced by each pulse is sustained after the pulse has died away by means of a generator which applies to the spark plugs a voltage capable of sustaining but not initiating sparks across the spark plugs. The generator is per se capable of developing a continuous output so as to maximize the spark energy and to allow the duration of the spark to be selected as desired. The output of the generator may be applied to the spark plugs continuously in which case the effect of increased impedance to the spark produced on combustion is used to terminate the spark. Alternatively, the output of the generator can be switched to terminate the spark.
