摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of stably injecting fuel by restricting influences of the fuel pressure and the fluctuation of the pressure when closing and opening the valve.SOLUTION: A needle 30, an inner piston 60 and an outer piston 70 are formed to satisfy the relation S=S-Sand S=S. When the needle 30 is closed, an end surface 71 of the outer piston 70 on a movable core 40 side abuts on a core step surface 53 of a fixed core 50, and the movement of the outer piston 70 in the valve closing direction is thereby regulated, and the outer piston 70 is separated from a piston step surface 63. When the needle 30 is being moved from a valve closing state to a valve opening state, the end surface 71 of the outer piston 70 abuts on the piston step surface 63 of the inner piston 60, and the outer piston 70 is pushed to move in the valve opening direction. When the needle 30 is being moved from the valve opening state to the valve closing state, the end surface 71 of the outer piston 70 abuts on the core step surface 53 of the fixed core 50, and the outer piston 70 is thereby regulated in the movement thereof in the valve closing direction.

摘要： PROBLEM TO BE SOLVED: To effectively control knocking during compression self-ignition combustion control of an engine.SOLUTION: A control device performs compression self-ignition combustion control for combusting a mixture gas by injecting fuel into a cylinder in NVO period (a negative valve-overlap period), in which both an exhaust valve 17 and an intake valve 16 are closed, and by causing self-ignition of the mixture gas using compression in a compression process. When knocking is detected during the compression self-ignition combustion control, the control device performs knock reduction control for correcting a fuel injection quantity in the NVO period to reduce knocking. When a pressure increase rate (increase rate of cylinder pressure during combustion) is lower than a predetermined threshold value, the control device determines that the fuel injection quantity in the NVO period is low and increases the fuel injection quantity in the NVO period. When the pressure increase rate is equal to or higher than the threshold value, the control device determines that the fuel injection quantity in the NVO period is high and decreases the fuel injection quantity in the NVO period. Thus, the control device controls the fuel injection quantity in the NVO period within a proper range (where knocking hardly occurs) in the NVO period.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve promoting further atomization and easily adjusting fuel spray. SOLUTION: Jet hole 60 includes a first hole part 61, a first hole part 62 and a second hole part 63. When the first hole part 61 and the second hole part 63 of the first hole part 62 are extended, each extended line crosses inside of the second hole part 63. Consequently, fuel flowing in the second hole part 63 from the first hole part 61 or the first hole part 62 impinges on fuel flowing out from the first hole part 62 or the first hole part 61 when the same flows in the second hole part 63. Turbulence of fuel flow occurs thereby. Impinged fuel is guided to the second hole part 63 and is injected. Injection direction and unnecessary scatter of fuel can be prevented thereby. Consequently, further atomization of fuel is promoted by turbulence of flow and shape and injection position of fuel spray can be simply adjusted. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a high pressure pump capable of accurately controlling a fuel discharge amount.SOLUTION: A needle guide 16, which supports a needle 26 fixed at a movable core 12 movably in a reciprocating manner between a movable core chamber 24 in which the movable core 12 is accommodated and a supply passage 48 in which a valve seat 23 are provide, includes a communication hole 25 communicating the movable core chamber 24 and the supply passage 48. An opening cross-sectional area of the communication hole 25 of the needle guide 16 is set in a range where a relation is maintained in which a fuel discharge amount decreases according as energization time to a coil 13 is getting later. Thereby, in the suction step of a high pressure pump, after the needle 26 presses a suction valve 20 to a stopper side by energizing force of a second spring 14, the movable core 12 and the needle 26 are suppressed to bounce to a fixed core side. Therefore, the relation of the energization time to the coil 13 and the fuel discharge amount is maintained, and the fuel discharge amount of the high pressure pump can be controlled accurately.

摘要： PROBLEM TO BE SOLVED: To easily provide a fuel injection valve that is slidable while ensuring gas-tightness of sliding portions, and further has a good sealing performance during valve closing.
SOLUTION: A needle 2 that reciprocates based on a pressure difference between a first pressure chamber 51 and a second pressure chamber 52 is divided into a piston member 21 for gas-tightly separating the first pressure chamber 51 and the second pressure chamber 52 from each other by being slidably inserted into a nozzle body 1, and a seating member 22 where a seat portion 223 is formed. Further, the piston member 21 and the seat member 22 are biased by spring members 61, 62 in an orientation that they come into close contact with each other. Since the needle 2 is divided into the piston member 21 and the seat member 22, the piston member 21 is positioned following a first guide hole 111 and a second guide hole 112. The seat member 22 is positioned following a valve seat 122.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve in which atomization of fuel injected from an injection hole is promoted, without increasing the size of the fuel injection valve. SOLUTION: The fuel passes through a slit-like second hole part 42, so that the fuel is in a flat liquid column and the fuel flows into a first hole part 41. A part on a first hole part 41 side of the second hole part 42 is connected with a position not including a center shaft of the first hole part 41, and is connected in the tangential direction of a side face part 44 of the first hole part 41 in the end part on the first hole part 41 side. The fuel flowing from the second hole part 42 into the first hole part 41 is guided by the side face part 44 of the first hole part 41 and is swirled. Therefore, a swirl flow of the fuel is injected from the injection hole 40. Since the first hole part 41 is connected with the second hole part 42 in an injection hole plate 30 at an angle α, occupation area of the second hole part 41 in a radial direction of the first hole part 41 is reduced. Therefore, atomization of the fuel injected from the injection hole 40 is promoted without increasing the size of the fuel injection valve. COPYRIGHT: (C)2006,JPO&NCIPI
