An ignition system for a stratified charge internal combustion engine is disclosed. The engine has at least one combustion chamber and a fuel injection means effective to inject fuel in a conical spray pattern into a predetermined zone of the combustion chamber for establishing a stratified charge. The system has walls dening a plasma ionizing chamber with an outlet orifice, electrical discharge means to apply an electrical charge across the plasma ionizing chamber causing the contents thereof to be shock heated to an ionized condition and released through the outlet orifice as a jet, and means interrupting the outlet orifice to form said plasma jet into a hollow cone and to direct the conical jet into the zone of the injected fuel.
