Title:
FUEL INJECTION VALVE OF INTERNAL COMBUSTION ENGINE AND METHOD FOR DRIVING THE SAME
Document Type and Number:
Japanese Patent JPH11193763
Kind Code:
A
Abstract:
To make the injection rate variable in one fuel injection cycle by freely controlling the lift of the needle of the fuel injection valve of an internal combustion engine.
A needle 10 having a differential pressure boundary plate 30 that separates into upper portion and lower portion of a differential pressure chamber 31 that communicates with two accumulators 80, 81 moves up and down to compensate each change in the capacity between those accumulators 80, 81 of the upper and lower portions of the piston caused by the movement thereof along with sliding movement of the electrostrictive actuator 60. The voltage applied to the electrostrictive actuator 60 is gradually controlled such that the lift of the needle 10 can be freely changed.
