Abstract
A fuel injection apparatus for an internal combustion engine comprising: a nozzle body; a nozzle formed at the bottom of the nozzle body; an electroexpansive actuator having the electroexpansive effect; a valve member, slideably mounted within the nozzle body; and a fuel chamber formed between the electroexpansive actuator and the valve member. When the electroexpansive actuator expands to reduce the volume of the fuel chamber, the valve member is moved in the closed direction of the nozzle. When the electroexpansive actuator contracts to increase the volume of the fuel chamber, the valve member is moved in the open direction of the nozzle.
