    Abstract: A fastening member (100) for fastening a first component (118) to a second component (110) in an end-to-end configuration along a common axis (A) is disclosed. The fastening member (100) comprises a first portion (124) having a threaded region for engagement with a corresponding threaded region (120) of the first component (118), a second portion (126) for applying a retaining force to the second component (110) to hold the first and second components (118, 110) in sealing engagement, and a deformable portion (130) intermediate the first and second portions (124, 126). The fastening member is particularly suitable for use as a cap nut in a fuel injector of the type having a cylinder pressure sensor integrated into the cap nut.

    Abstract: A dosing device (1) is provided that is suitable for administering a reagent (2) into an exhaust chamber (4) of an internal combustion engine. The device (1) comprises a nozzle body (6) and an insulating jacket (5) wherein the jacket (5) is mounted to the nozzle body (6) at one or more mounting points (8,9), and wherein the dosing device (1) is adapted to engage with a port (10) located in the wall of an exhaust chamber (4). The insulating jacket (5) defines a compartment (11), which can comprise an insulating material or can be substantially evacuated. The dosing device (1) of the invention is advantageously insulated from the elevated temperatures in the surrounding environment, thereby allowing for the reagent to be maintained at an optimal working temperature range.

    Abstract: An injection nozzle for injecting fuel into a combustion chamber of an internal combustion engine is disclosed. The injection nozzle comprises a nozzle body (13) having a bore (17) for receiving fuel from a supply line (12) for pressurised fuel, an outlet (16) from the bore (17) for delivering fuel to the combustion chamber, in use, and a valve needle (15) slidable within the bore (17) between a closed state in which fuel flow through the outlet (16) into the combustion chamber is prevented, and an injecting state in which fuel flow through the outlet (16) into the combustion chamber is enabled. Movement of the valve needle (15) is controllable by varying the fuel pressure within a control chamber, in use. The valve needle (15) comprises a needle guide portion (22) arranged to guide sliding movement of the valve needle (15) within the bore (17). The injection nozzle also comprises a restriction (21a) within the bore (17) for restricting the flow of fuel through the bore (17). The restriction is defined by a restrictive element (21) which is movable with the needle (15) and is located upstream of the needle guide portion (22). When the needle (15) is in the injecting state in use, the fuel pressure at the outlet (16) is substantially the same as the pressure of fuel in the bore (17) immediately downstream of the restrictive element (21) and is less than the pressure of fuel supplied to the bore (17) from the supply line (12).
