A combined assembly for filtering and calibrating a fuel injector arranged in an internal combustion engine, the combined filtration and calibration assembly extending along a longitudinal axis and comprising a calibration sleeve provided with a longitudinal bore and defining a multitude of filtration holes. The combined filtration and calibration assembly has a calibrated opening in the bore.

Method for producing a combined filtration and calibration assembly

A coil assembly in a fuel injector includes a magnetic core and; a winding wound around the core, the winding being overmoulded and forming a cylindrical overmoulding. An axial blind hole extends towards the interior of the coil assembly from a first surface to a distal end, the blind hole being suitable for housing at least one spring for loading a magnetic armature. The coil assembly is provided with a degassing hole passing through the core and the overmoulding from the blind axial hole to an axial outer cylindrical surface, the degassing hole being provided in the magnetic core and having a restriction that is arranged in a first section that is proximal to the blind axial hole.

Coil assembly

A fuel injector includes a needle that can move between an entirely open position and a closed position is provided with a device for identifying the position of the needle, in which an electrical circuit is closed in the two extreme positions, the needle being in electrical contact with ground, the circuit being open in any other intermediate position of the needle, the needle not being grounded.

Fuel injector with device for detecting needle position

A subassembly for a high pressure fuel injector control valve includes a control valve member and a sleeve attached to a stem of the control valve member, the sleeve extending along at least a partial axial length of the stem of the control valve member, and wherein a clearance, provided between the sleeve and the control valve member, is in fluid communication with the control chamber such that during use, pressure compensation occurs, as the sleeve is caused to expand and seal against the control valve bore, thereby preventing leakage of fuel within the control valve assembly.

Control valve assembly

A control valve assembly for controlling fuel pressure in a control chamber of a fuel injector. The control valve assembly comprising a valve member arranged in a bore provided in a valve housing, at least one of the valve member and the valve housing being moveable with respect to the other, wherein the valve member comprises a fuel-receiving cavity arranged to receive fuel that distorts at least a portion of the valve member so as to increase an external dimension thereof.

Control valve assembly and fuel injector incorporating a control valve assembly

A fuel injector includes fixed metal components, in particular an injector body, a solenoid actuator equipped with a retaining spring that holds a control valve stem, a control valve body including a seat for the control valve stem, a spacer between the body of the control valve and an injection nozzle, a control chamber, and an injection needle seat. The fuel injector also includes movable metal components, in particular the control valve stem and an armature thereof and an injection needle. Surfaces of the metal components that are in contact with one another are contact surfaces. Resistive surface coatings are arranged on a number of the contact surfaces. The overall electrical resistivity of the injector between the body of the solenoid actuator and the body of the injector varies by at least three distinct ohm values intermittently according to the kinetics of the injection needle of the injector.

Fuel injector

The present invention relates to a control valve for a fuel injector. The control valve has a control valve body which defines a supply passage for high pressure fuel. A control chamber and a pressure compensating chamber are provided in the control valve. The control chamber and the pressure compensating chamber are both in fluid communication with the supply passage. A control valve member is provided for controlling fuel pressure in the control chamber. The pressure compensating chamber is spaced radially outwardly from the control chamber. The invention also relates to a control valve member having a pressure compensating cavity.

Control valve

A connector arrangement for a fluid system includes a fuel injector that defines a first fluid passage having a connector, a pipe that is engageable with the connector of the first fluid passage, preferably to form a high pressure seal, and a nut arranged to connect the pipe to the connector of the first fluid passage. A chamber is defined between the nut and the fuel injector, such chamber serving to collect leaked fluid from the first fluid passage. The fuel injector is provided with a second fluid passage having a first end in communication with the chamber and a second end in communication with a low pressure drain such that leaked fuel is provided with a drain path.

Connector arrangement for a fluid system

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.
