Title:
ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/087799
Kind Code:
A1
Abstract:
An engine (1) is provided with an ignition device (200). The ignition device (200) is provided with: a central electrode (231); a grounding electrode (232) which is provided corresponding to the central electrode (231) and which is connected to ground (GND); and a potential rise promoting unit (250) disposed between ground (GND) and the grounding electrode (232). According to such a configuration, by raising the potential on the grounding electrode 232 side, an electric field in an electric discharge region formed by the central electrode (231) and the grounding electrode (232) can be strengthened before spark discharge occurs. As a result, the voltage when spark discharge begins can be suppressed, and a deterioration in an electrode unit configured from the central electrode (231) and the grounding electrode (232) can be suppressed.
