Embodiments relate to a removal adapter configured to engage a fuel injector secured to an engine and to allow for the removal of the fuel injector from the engine without damaging the fuel injector. The removal adapter is slid over the fuel injector and engages the fuel injector via a ridge. The engagement via the ridge places most, if not all, of the force on the strongest part of the fuel injector.

There is disclosed a method of operating an engine assembly including a combustion engine and a common-rail injector. The method includes: injecting fuel into a combustion chamber of the combustion engine via the common-rail injector thereby generating a backflow of fuel; and powering an actuator using at least a portion of the backflow of fuel. An engine assembly including the combustion engine is disclosed; the engine assembly having a fuel circuit fluidly connecting a fuel source, the common-rail injector, and the second injector outlet together. The fuel circuit has an actuator sub-circuit operatively connected to an outlet of the common-rail injector and an actuator fluidly connected to the actuator sub-circuit.

A fuel injector tip for a fuel injector. The fuel injector tip includes an inner tip surface and an outer tip surface that is opposite to the inner tip surface. At least one orifice extends through the fuel injector tip from the inner tip surface to the outer tip surface, and is configured to atomize fuel flowing therethrough to generate a fuel mist. The fuel injector tip is three-dimensionally printed.

In a sealing structure, a seal ring stands between an outer peripheral member and an inner peripheral member installed thereto. A taper-like outer peripheral surface having smaller diameter toward an inserting direction of the inner peripheral member and an installation portion outer peripheral surface extending from the small diameter end portion are formed on an outer peripheral surface of the inner peripheral member. A stepped surface positioned closer to the inserting direction side and directed to an opposite direction to the inserting direction, and an installation portion inner peripheral surface extending from an outer diameter end of the stepped surface in the opposite direction are formed on an inner peripheral surface of the outer peripheral member. The seal ring is arranged in a compressed state between the taper-like outer peripheral surface and the installation portion outer peripheral surface, and the stepped surface and the installation portion inner peripheral surface.
