Title:
燃料噴射ノズルおよびそれを用いた燃料噴射制御装置
Document Type and Number:
Japanese Patent JP4591555
Kind Code:
B2
Abstract:
Needles include a cylindrical outer needle that is brought into contact with and moved away from a nozzle body (113) to open and close an injection hole (1132) and an inner needle (112), slidably inserted in the outer needle (111), that is moved into and out of a sack-tip-portion space (171). When the inner needle (112) enters the sack-tip-portion space (171) and completely occupies the sack-tip-portion space (171), the fuel injection direction B is made downward relative to the injection-hole central axis C. Thus, it is possible to control the fuel injection direction B by controlling the amount of lift of the inner needle (112).
