摘要： An inner side wall surface of a gap forming member, which is opposed to a flange outer wall surface of a flange of a needle, is slidable relative to the flange outer wall surface. Also, an outer side wall surface of the gap forming member, which is opposed to a stationary core inner wall surface of a stationary core, is slidable relative to the stationary core inner wall surface. The flange outer wall surface and the outer side wall surface are curved to project in a radially outer direction of a housing in a cross section thereof taken along an imaginary plane, which includes an axis of the housing.

摘要： A method comprises determining either the coefficient for the equation relating the injection timing distance of a bushing to the angle of rotation of a shaft of an engine, or the desired effective injection stroke reduction; and calculating at least one of the following: the modified injection timing distance by multiplying the desired angle of retardation of the injection timing by the coefficient and adding that product to the original injection timing distance of the bushing, and the modified injection duration distance by subtracting the desired effective injection stroke reduction from the original injection duration distance.

摘要： A fuel injection valve injects a fuel into the combustion chamber or into the injection port of an internal combustion engine, the valve being actuated by an actuator assembly that includes a small displacement actuator and a large displacement actuator. The method includes commanding the small displacement actuator to move the valve member to a first open position corresponding to a first flow area and commanding the large displacement actuator to move the valve member to a second open position corresponding to a second flow area that is larger than the first flow area such that the ratio between the second flow area and the first flow area is at least 15:1. The fuel injection valve can also be operated to alternatively inject two different fuels, one of the fuels being a gaseous fuel and the other one being a liquid fuel.

摘要： An objection of the present invention is to provide a fuel injection valve with a reduced variation in an injection amount and, in order to achieve this object, a method for adjusting stroke, the method being able to correct change in an amount of stroke caused by welding. In the method for adjusting the amount of stroke of a movable member of a fuel injection valve including a nozzle member having a seat face, a nozzle holder member to which the nozzle member is joined by welding, and the movable member having a valve seat portion for coming in contact with the seat face, the amount of stroke of the movable member is adjusted by plastically deforming a deformable portion provided to the nozzle holder member after joining the nozzle member and the nozzle holder member by welding.
