ABSTRACT:
A spark ignition engine has a crankshaft speed pulse generator and a plurality of cylinders each cylinder containing a spark plug. Each plug is connectable to a high voltage ignition winding by way of a reed relay. The relays are divided into two groups and, with a periodicity dependent on generator output, a selected relay in each group is closed immediately prior to generation of voltage in the winding and opened when the voltage has been dissipated. Although both plugs connected to the selected relays produce a spark only one of the cylinders contains fuel mixture and, consequently, one one power stroke occurs.
