This paper describes an improvement in an internal combustion engine having a plurality of cylinders and reciprocating pistons therein arranged to sequentially have successive intake, compression, power and exhaust strokes. The ignition means including a high tension current source, timing means have a first current control means for momentarily controlling current flow in the high tension source, and distributor means having a first distributor arm rotating synchronously with the reciprocation of the pistons and connected to the high tension current source and adapted to momentarily communicate a first spark to a spark plug in each cylinder just prior to the commencement of its power stroke. The improvement comprising a second current control means for each cylinder adjacent the first current control means for momentarily controlling the current in the high tension source a second time, and the distributor means having a second rotating distributor arm electrically connected to the first distributor arm for successively momentarily communicating a second spark to the spark plug in each cylinder at the commencement of the power stroke to more completely ignite combustibles in the cylinders.
