摘要： A dual fuel injection valve separately and independently injects two different fuels into a combustion chamber of an internal combustion engine. A first fuel is delivered to the injection valve at injection pressure and a second fuel is either raised to injection pressure by an intensifier provided within the injection valve, or delivered to the injection valve at injection pressure. Electronically controlled valves control hydraulic pressure in control chambers disposed within the injection valve. The pressure of the hydraulic fluid in these control chambers is employed to independently actuate a hollow outer needle that controls the injection of the first fuel. Disposed within the outer needle is an inner needle that controls the injection of the second fuel. The outer needle closes against a seat associated with the injection valve body and the inner needle closes against a seat associated with the outer needle.

摘要： A dual fuel injection valve separately and independently injects two different fuels and comprises a dual needle assembly with a hollow open-ended outer needle and an inner needle disposed within the hollow interior. A cap cooperates with the outer needle to cover the open end, and the outer needle and the cap together comprise the inner valve body. The outer and inner needles are each movable independently from each other between respective open and closed positions. A spring disposed between the cap and the inner needle contributes to biasing the inner needle in the closed position. The cap can be joined to the outer needle, whereby the cap can provide a limit to the movement of the inner needle. In another embodiment the cap can be detached from the outer body, allowing the spring to space the cap away from the outer needle, assisting with biasing the outer needle closed.

摘要： A gaseous and liquid fuel injection valve for an internal combustion engine comprises an injection valve body that houses two separate concentric fuel injection valve assemblies. The first valve assembly is a pilot fuel needle valve assembly, which comprises a first needle movable in the direction of the longitudinal axis of the body between an open and a closed position. The second valve assembly is a gaseous fuel needle valve assembly, which comprises a second needle movable in the direction of the longitudinal axis between an open and a closed position. The gaseous fuel needle valve assembly controls the injection of gaseous fuel into the combustion chamber through a plurality of gaseous fuel holes formed in a nozzle tip of the gaseous fuel needle valve assembly. At least one of the nozzle tips is rotatable to thereby change the position of the pilot fuel holes with respect to the gaseous fuel holes. The number of the plurality of pilot fuel holes is different from the number of the plurality of gaseous fuel holes.

摘要： A hydraulically actuated dual fuel injector separately injects two fuels into a combustion chamber of an internal combustion engine. In particular, the two fuels may be controlled quantities of a first liquid fuel and a second gaseous fuel that are used to fuel a diesel engine. The injector preferably begins injecting the first fuel sequentially before beginning to inject the second fuel. The dual fuel injector comprises: (a) an injector body; (b) a hydraulic fluid inlet port formed in the injector body for enabling pressurized hydraulic fluid from a hydraulic fluid source to be introduced into the interior of the injector body, said hydraulic fluid being of sufficient pressure to maintain sealing and to prevent leakage of the gaseous fuel into the hydraulic fluid; (c) a first fuel inlet port formed in the injector body for enabling a first fuel to be introduced into the interior of the injector body; (d) a first injection valve disposed within the injector body fluidly connected to the first fuel inlet port for controlling injection of the first fuel from the injector through a first fuel ejection port; (e) a second inlet port formed in the injector body for enabling a second fuel to be introduced into the interior of the injector body; (f) a second injection valve disposed within the injector body fluidly connected to the second inlet port for controlling injection of the second fuel from the injector through a second fuel ejection port; (g) a first two-way control valve which controls the flow of the hydraulic fluid to actuate the first injection valve; (h) a second control valve which controls the flow of the hydraulic fluid to actuate the second injection valve; (i) a metering device within the injector body for metering the amount of first fuel injected by the first injection valve; and (j) a seal in the injector body which prevents leakage of the second fuel within the injector body.
