    Abstract: The present invention relates to a fuel injector (101; 201) for use in delivering fuel to an internal combustion engine. The fuel injector (101; 201) includes a nozzle (105; 205) having a valve needle (107; 207) which is movable with respect to a valve needle seat (117; 217). The valve needle (107; 207) travels through a range of movement between a closed position and an open position to control fuel delivery through at least one nozzle outlet (109). The valve needle (107) cooperates with a needle sleeve (111) or a control member (211) which is located in a piston guide (133). The valve needle (107) is movable relative to the needle sleeve (111) or the control member (211). The needle sleeve (111) or the control member (211) is movable relative to the piston guide (133; 233). The invention also relates to a method of operating a fuel injector (101; 201); and a fuel injector control unit.

    Abstract: An overhead-camshaft internal combustion engine is disclosed, in which the fuel pumps are arranged to use efficiently the space within a cylinder head assembly (100) of the engine. The cylinder head assembly (100) includes a cylinder head block (102), and the engine comprises a camshaft (106) mounted longitudinally with respect to the cylinder head assembly (100), the camshaft (106) being rotatable about a camshaft axis (A) and having a plurality of inlet and exhaust cams for actuating associated inlet and exhaust valves (116a; 116b) of the engine, and at least one fuel pump comprising a unit pump assembly (110) driven directly by a respective pump cam (130) provided on the camshaft (106), the unit pump assembly (110) being elongate to define a pump axis (P). The engine further comprises a plurality of rocker arms (118) driven by the inlet and exhaust cams and arranged to actuate the inlet and exhaust valves (116a, 116b). Each rocker arm (118) is pivotable about a rocker arm axis (R) which is substantially parallel to the camshaft axis (A). The or each pump assembly (110) is mounted between the rocker arm axis (A) and the cylinder head block (102).

    Abstract: A non-return valve assembly (100) for a high-pressure fuel injection system is disclosed. The valve (100) comprises a valve chamber (102) defined in part by a first body (106) and in part by a second body (108) and defining a valve chamber wall (118), an inlet passage (110) formed in the first body (106) and opening into the valve chamber (102) at a valve seat (116) defined by the first body (106), an outlet passage (112), and a valve ball (114) received within the valve chamber (102) and engageable with the valve seat (116) so as to interrupt fluid flow from the outlet passage (112) to the inlet passage (110) through the valve chamber (102). The valve chamber wall (118) comprises a plurality of guide portions (122a) to guide the valve ball (114) in substantially linear movement within the valve chamber (102).
