Abstract
An electrode shape forming method includes generating discharge between a central electrode and an outer electrode of an ignition plug of an engine in a state in which the engine is driven by an electric motor and metal powder is supplied to a combustion chamber of the engine. As a result of the generating the discharge between the central electrode and the outer electrode of the ignition plug, the metal powder is thermally sprayed to one or both of the central electrode and the outer electrode.
Claims6
An electrode shape forming method comprising:
- generating discharge between a central electrode and an outer electrode of an ignition plug of an engine in a state in which the engine is driven by an electric motor and metal powder is supplied to a combustion chamber of the engine,
- wherein, as a result of the generating the discharge between the central electrode and the outer electrode of the ignition plug, the metal powder is thermally sprayed to one or both of the central electrode and the outer electrode.
An electrode shape forming device comprising:
- an electric motor coupled to an output shaft of an engine;
- a powder supply unit that is attached to the engine and stores metal powder therein;
- and
- a voltage application unit that is coupled to an ignition plug of the engine and is configured to generate discharge between a central electrode and an outer electrode of the ignition plug,
- wherein the voltage application unit is configured to thermally spray the metal powder to one or both of the central electrode and the outer electrode as a result of generating the discharge between the central electrode and the outer electrode in a state in which the engine is driven by the electric motor and the metal powder is supplied to a combustion chamber of the engine by the powder supply unit.
