1. A droplet ejector for an internal combustion engine having an ejection port for ejecting droplets of liquid fuel, wherein:
the ejection port has one or more ejection orifice for ejecting the droplets, and
the ejection port or the droplet ejector is electrically connected directly to the combustion chamber of the internal combustion engine by a conductor for suppressing potential increase of the ejection port due to flow electrification, and electrostatic capacity of the ejection port or the droplet ejector is made larger than that in the condition un-connected with the combustion chamber.
