Abstract
An apparatus for conveying high pressure actuating fluid such as engine lubricating oil to hydraulically actuated electronically controlled injectors (HEUIs) in an internal combustion engine. The apparatus has a fluid rail with outlet ports to communicate the actuating fluid to the injectors which is adapted to be mountable on an engine so as to be located in use above the actuating fluid inlets of the injectors. A fuel injection system for an internal combustion engine incorporating such apparatus is also described.
Claims5
An apparatus for conveying high pressure actuating fluid to a hydraulically actuated electronically controlled injector in an internal combustion engine, comprising:
- a fluid rail defining an actuating fluid reservoir and having an outlet port connectable to communicate actuating fluid to an actuating fluid inlet of an injector;
- a cylinder head having a face;
- a gas exchange valve operating mechanism being mounted on the cylinder head and extending above the face;
- fluid rail support connected to the cylinder head and locating said fluid rail above the gas exchange valve operating mechanism, above the actuating fluid inlet of the injector, above the face, and closely adjacent the injector.
