A fuel injector includes an upper housing having an outer peripheral surface; a nozzle tip with a nozzle opening which serves as an outlet to fuel from the fuel injector; and a valve needle which is selectively moveable between a first position which prevents fuel flow and a second position which permits fuel flow. The fuel injector also includes an inlet sleeve which includes an inner peripheral surface which circumferentially surrounds, and mates with, the outer peripheral surface of the upper housing. The inlet sleeve is fixed to the upper housing, thereby preventing relative movement between the inlet sleeve and the upper housing. The inlet sleeve includes external threads which are configured to mate with complementary internal threads of a nut which secures a fuel supply conduit to the upper housing.

Fuel injector

An electrical connector assembly of a fuel injector includes a body with external walls defining an internal volume and an internal wall dividing the connector in a first part adapted to be fixed in a complementary engagement with the body of the injector and, in a second part adapted to receive another electrical connector. The electrical connector assembly also includes at least one electrical terminal extending through the internal wall from an inner extremity protruding in the inner volume of the first part of the body, to an outer extremity protruding in the outer volume of the second part of the body. The outer extremity is shaped to receive in a complementary engagement an electrical terminal of said another electrical connector. The connector assembly is adapted to be in fluid communication with the back leak return conduit of the injector.

Connector assembly for a fuel injector

The invention relates to an anti-rotation device of a fuel lance arranged in a bore extending through a cylinder head of a cylinder head from an intake opening until a hole provided for receiving a fuel injector, the lance allowing high-pressure fuel to circulate from an intake opening of the lance until the outlet opening of the lance engaging with the intake opening of the fuel injector, the fuel lance including a nut for being screwed into the intake opening of the bore and a tubular member compressed between the nut and the injector, the lance also including the anti-rotation device. The anti-rotation device is a resilient element which is deformed by rotation of the nut, such as to be blocked between the tubular member and an inner wall of the bore, and thus prevent rotation of the tubular member when the nut is screwed.

Anti-rotation device of a fuel lance

A flat electrical terminal is produced from a metal plate having a terminal thickness and of which one end is delimited by a first edge at the center of which a slot opens, extending along a main axis and allowing the complementary insertion and electrical connection of another flat terminal electrically connected to a device. The two opposing sides of the slot are provided with protuberances, each extending towards the opposite side such that the other terminal is designed to be in contact with the tops of the protuberances.

A fuel lance assembly for an engine comprises: a fuel lance to be received in a passage provided in a cylinder head and a connection arrangement comprising an inlet adapter for securing the fuel lance within the passage. The fuel lance comprises a tubular member of constant external diameter, arranged to be received, in use, within the passage and having a first end being shaped for cooperation with a seating surface of a fuel injector of the engine, and a second end being shaped for cooperation with the inlet adapter, and being provided with a bore therethrough to define a fuel flow path between the first end and the second end of the fuel lance. The inlet adapter is provided with an attachment system for engaging a compatible attachment system of the cylinder head, and has a proximal region for receiving a high pressure fuel pipe, and wherein the inlet adapter has a distal region provided with an opening being adapted to receive the second end of the fuel lance. A fuel lance and a fuel supply line arrangement are also provided.
