    摘要： An outboard motor powerhead section includes an engine having vertically stacked cylinders. The engine includes intake passages extending through the cylinder head to the cylinders. A fuel rail extends along a vertical center axis alongside the cylinder head. Receiver cups are coupled to the fuel rail and vertically spaced from one another such that each receiver cup is associated with a respective cylinder. Each receiver cup has a respective connector passage providing fluid communication between the fuel rail and receiver cup. Fuel injectors are respectively coupled to the receiver cups. Each fuel injector has an inlet end located in a respective receiver cup and extends along a center axis toward a nozzle end that extends into a respective intake passage. A cowl covers the engine. The vertical center axis of the fuel rail is located relatively more inboard with respect to the engine than is at least one connector passage.

    摘要： A fuel injection valve includes: a needle valve including a seat portion on a tip side thereof; a nozzle body including a seat surface on which the seat portion is placed, and a swirl stabilization chamber on a downstream side of the seat surface, the nozzle body having an injection hole formed so as to have an inlet in the swirl stabilization chamber; a swirl flow generating portion having swirl grooves configured to give a swirling component to fuel to be introduced into the swirl stabilization chamber; and a fuel collision portion provided in a tip portion of the needle valve, the fuel collision portion being configured such that, in a state where the needle valve is opened, the fuel collision portion intersects with a virtual surface extended toward the injection hole from the seat surface included in the nozzle body. This allows dead fuel to be retained in the swirl stabilization chamber and to be introduced into the injection hole in a state where a swirling component has been given to the dead fuel from fuel having the swirling component.

    摘要： A nozzle for a fuel injector is disclosed. The nozzle may have an internal axial nozzle bore. The nozzle may also have at least one orifice passing from the nozzle bore radially outward through a wall of the nozzle at a tip end. Further, the nozzle may have a sac volume formed in the tip end and defined by a bore radius and a tip radius. The bore radius may be generally perpendicular to the central bore. The tip radius may be generally parallel to the central bore. The tip radius may be less than the bore radius.
