Abstract
An arrangement for supplying fuel from a fuel pressure source located on an outside of an engine enclosure to a fuel injector located on an inside of the engine enclosure includes a fuel pipe for transporting fuel from the fuel pressure source to the fuel injector via an opening in the engine enclosure, and a seal for sealing the fuel pipe at the opening. The seal includes a first part configured for a sealing contact around the fuel pipe and a second part configured for a sealing contact around a sleeve extending around the opening. An internal combustion engine provided with such an arrangement and a method for providing an internal combustion engine with such an arrangement are also provided.
Claims29
An arrangement for supplying fuel from a fuel pressure source located on an outside of an engine enclosure to a fuel injector located on an inside of the engine enclosure, the arrangement comprising:
- a fuel pipe for transporting fuel from the fuel pressure source to the fuel injector via an opening in the engine enclosure, wherein the fuel pipe is a separate component from the fuel injector, and wherein the fuel pipe is connectable to the fuel injector by a fastening device located at an injector end of the fuel pipe;
- a seal for sealing the fuel pipe at the opening, wherein the seal comprises a first part configured for a sealing contact around an outer exterior circumferential surface of the fuel pipe and a second part configured for a sealing contact around a sleeve, the sleeve extending around the opening, wherein the first part of the seal is slidably mounted onto the fuel pipe.
A method for providing an internal combustion engine with a fuel supply arrangement comprising a fuel pipe for transporting fuel from a fuel pressure source located outside an engine enclosure to a fuel injector located inside the engine enclosure, wherein the fuel pipe is separate from the fuel injector, and wherein the fuel pipe is connectable to the fuel injector by a fastening device located at an injector end of the fuel pipe, the method comprising the steps of:
- providing a fuel pipe provided with a seal having a first part configured for a sealing contact around an outer exterior circumferential surface of the fuel pipe and a second part configured for a sealing contact around a sleeve extending around an opening in the engine enclosure, wherein the seal is movable along the fuel pipe, introducing the injector end of the fuel pipe through the opening and positioning the fuel pipe, and moving the seal relative to the fuel pipe to a position in which the second part of the seal is positioned around and in contact with the sleeve.
