|Distributorless ignition systems
||In a waste spark system, each spark plug is fired by a high voltage impulse from an ignition coil shared with a companion cylinder.
||In systems which employ an individual coil for each cylinder, the coils can be placed in an insulated cassette with each coil connected directly to its spark plug.
|Distributorless ignition system timing||Timing for the distributorless ignition system is controlled by an electronic control unit or ECU. Identification of each pair of cylinders is provided by a dual crank sensor attached to the engine timing cover.|
