Distributor with sliding contacts

摘要

In order to prevent a plasma jet energy from discharging through a spark plug of an internal combustion engine prior to the proper ignition timing, an ignition distributor with a plurality of sliding contacts is proposed. A plasma jet energy as well as a spark energy is selectively delivered to the spark plugs at a predetermined ignition timing through a plurality of contact surfaces mounted on a shaft rotatable in synchronous with the engine crankshaft, thereby an irregular discharge of the plasma jet energy is eliminated.
