摘要： An injection nozzle (10), for use in a fuel injector for an internal combustion engine, has an inner valve needle (26) which is engageable with an inner valve seating (24, 58) to control fuel delivery through one or more first nozzle outlets (14), and an outer valve (28) which is engageable with an outer valve seating (24, 70) to control fuel delivery through one or more second outlets (16). The outer valve (28) is provided with a valve bore (36) within which at least a part of the inner valve needle (26) is received. Coupling means (46, 48) are provided for coupling movement of the inner valve needle (26) to the outer valve (28) in circumstances in which the inner valve needle (26) is moved away from the inner valve seating (24, 58) through an amount exceeding a predetermined threshold amount (D). This allows the outer valve (28) to be lifted away from the outer valve seating (24, 70) to provide an increased injection rate. If only a reduced injection rate is required the inner valve needle (26) need only be lifted through an amount less than the threshold amount.

摘要： An injection nozzle (10) for use in a fuel injector for an internal combustion engine having a combustion space, the injection nozzle (10) includes a first valve needle (16) which is engageable with a first valve needle seating (34) to control fuel delivery through one or more first outlets (36) provided in a nozzle body (12). The or each first outlet (36) defines a first cross sectional flow area for fuel. The nozzle further comprises a second valve needle (22), coaxial with the first valve needle and engageable with a second valve needle seating (40) to control fuel delivery through a plurality of second outlets (38) provided in the nozzle body (10). The plurality of second outlets are arranged in one or more localised groups (38) of second outlets (38a,38b,38c), with each of the second outlets (38) having a cross sectional flow area equal to the first cross sectional flow area of the first outlet (36). The nozzle is of the two-stage lift type to provide a variable fuel injection rate depending on whether one of the valve needles (16,22) is moved alone to open one of the outlets or localised groups of outlets only to provide a relatively low injection rate, or whether the other of the valve needles is moved also to provide an increased injection rate.

摘要： An injection nozzle for an internal combustion engine, including a nozzle body provided with a bore which defines a valve seating surface, the nozzle body having a first nozzle outlet and a second nozzle outlet, a first delivery chamber upstream of said nozzle outlets, an outer valve member, moveable within the bore and itself provided with an axial bore. The outer valve member is engageable with an outer valve seat defined by the valve seating surface so as to control fuel flow from the first delivery chamber to at least the first nozzle outlet when the outer valve member lifts from its seat. The injection nozzle further includes an inner valve member, moveable within the axial bore and including first and second seating lines spaced apart axially from each other. Both seating lines are engageable with an inner valve seat defined by the valve seating surface so as to control fuel flow from a second delivery chamber to the second nozzle outlet when the inner valve member lifts from its seat. The inner valve member defines, at least in part, flow passage means such that fuel may flow from the first delivery chamber to the second delivery chamber.

摘要： A fuel injector comprising a nozzle body (10), a first outlet opening (15) having an axis (15 a ), a second outlet opening (19) having an axis (19 a ), and means (12, 17, 18) for controlling fuel delivery through the first and second outlet openings (15, 19). The axes (15 a , 19 a ) of the first and second outlet openings (15, 19) are arranged so as to intersect one another downstream of the outlet openings (15, 19) such that, when fuel is delivered through both the first and second outlet openings (15, 19), a combined spray formation is formed which is substantially equivalent to a single spray formation having been delivered from a single opening.
