摘要： A large two-stroke turbocharged compression-ignited internal combustion crosshead engine with a plurality of cylinders has at least one pressure booster for each cylinder for boosting fuel pressure, two or more electronically controlled fuel valves for each cylinder with an inlet of the two or more electronically controlled fuel valves being connected to an outlet of the at least one pressure booster. An electronic control unit is connected to the at least one pressure booster and the two or more electronically controlled fuel valves. The electronic control unit is configured to determine a start time for a fuel injection event, activate the at least one pressure booster ahead of the determined start time and pen the two or more electronically controlled fuel valves at the determined start time.

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 assembly comprising a fuel injector (19) having an injection outlet (19) and a fuel rail (17) in which the fuel injector is adapted to be supported. The fuel injector (19) has a tip (37) having an end from which fuel issuing from the outlet of the fuel injector is discharged. The tip (37) is adapted for location in an injection port (21), the tip being of flexible construction to accommodate some misalignment between the fuel rail (17) and the injection port (21).

摘要： In a fuel injection valve, it is possible to obtain spray in which the penetrating force of injected fuel is suppressed.The fuel injection valve includes a valve seat that forms a gap with a valve body, the gap allowing fuel to pass therethrough, and multiple injection holes that are located further downstream from the gap. The fuel to which pressure is applied flows out from the injection holes.When the flow velocity of the fuel in the gap formed between the valve body and the valve seat is indicated by meters per second, the flow velocity is set to be greater than a value obtained by multiplying the square root of the pressure applied to the fuel by 28. In this manner, the flow velocity in the gap increases, and flow velocity distribution inside the injection hole is uniformized, thereby suppressing an increase in penetration.

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 member of a fuel combustion system of an engine includes a hollow nozzle body. The nozzle body includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer opening. The inner surface defines an interior chamber and an inner opening. The orifice surface defines an orifice passage extending between, and in communication with, the outer opening and the inner opening. The orifice passage is in communication with the interior chamber via the inner opening. The orifice surface includes a boundary surface and a protrusion. The protrusion projects from the boundary surface radially inwardly into the orifice passage.

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.
