Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/148518
Kind Code:
A1
Abstract:
An internal combustion engine comprising: a positive voltage generation unit for generating positive voltage to be applied to an electrode exposed in a combustion chamber of a cylinder; a negative voltage generation unit for generating negative voltage to be applied to the same electrode; and a switching unit for selectively connecting either the positive voltage generation unit or the negative voltage generation unit to the electrode and applying either the positive voltage generated by the positive voltage generation unit or the negative voltage generated by the negative voltage generation unit to the electrode, during a single combustion in the cylinder. This minimizes the one-sided wearing out and longevity shortening of the electrode for ignition which is exposed in the combustion chamber of the cylinder of the internal combustion engine.
