Abstract
Ignition system for internal combustion engine in which combustion chambers in an internal combustion engine are shaped in such a manner that a microwave resonance easily causes a plasma discharge, microwaves are supplied from a microwave oscillator through respective coaxial cables to all the combustion chambers so that the combustion chambers resonate whenever the microwave power is injected, or so that when the combustion chambers reaches a resonatable condition, is the microwave power injected into the combustion chambers from the microwave oscillator; thereby causing plasma discharge to occur in the combustion chambers.
