Abstract
PURPOSE: To regulate a quantity and timing of a fuel injection by applying the same pressure of a fuel to the upper and lower ends of a needle valve inside a fuel injection valve and opening or closing the needle valve with an electronically controlled working oil.
CONSTITUTION: A fuel supply passage 8 opening to an end injection nozzle 4 is formed inside a main body 1. A needle valve 5 is disposed inside it, opening or closing the injection nozzle 4. Above the needle valve 5, a control piston 10 and a pressure piston 16 are integrated, reciprocating in a primary cylinder casing 9 and a secondary cylinder casing 15, respectively. An upper chamber 16a on the piston 16 is communicated with the supply passage 8 via a branch passage 17, generating a fuel pressure to be equivalently applied onto the upper and lower ends of the needle valve 5. A working oil pressure supply device consisting of a switch valve 31, an electronic controller 37 and other elements produces an oil pressure dependently on operation conditions and applies it into the lower chamber 9a of the piston 10 via supply passages 11a, 11 so as to open or close needle valve 5 under said pressure.
