Definitions
- This disclosure relates to fuel injectors and specifically to needle and nozzle arrangements therefor. Background to the invention
- a typical fuel injector comprises an actuator controlled valve needle adapted to be moved away from a valve seat so as to allow fuel to be dispensed into a combustion chamber.
- the needle is located along a central axis within a cylindrical nozzle body portion of the fuel injector These components work together as a valve to control fuel injection events.
- Both the nozzle body/seat and needle may have conical co-operating surfaces.
- the needle may be hydraulically controlled by the pressure of the fuel supplied to the injector. High fluid forces thereby act on the needle to drive its motion, particularly towards its closed position where the distal end, e.g. the conical surface of the needle tip, engages the (nozzle body) valve seat.
- the closing of such a needle valve arrangement is typically driven to be as fast as possible for the purpose of injector delivery requirements.
- this results in high velocity impact of the needle with the valve seat e.g. after every main injection; this leads to wear of the seat.
- seat wear results in changes to the total area exposed to high pressure fuel. This alters the degree of hydraulic force exerted on the needle resulting in performance drift. In extreme cases, for example regarding pilot injection where activation of the valve is for a very short periods, injection may be missed altogether as a result of seat wear.
- a nozzle arrangement for a fuel injector including a nozzle body having a longitudinal axis, and including a valve seat located towards the distal end thereof, and housing a needle located within said nozzle body and wherein said nozzle body and said needle define a nozzle body volume at the distal end of said nozzle, said needle adapted to be slidable within said nozzle body along said axis, to a closed position where the tip of the needle is in contact with the valve seat, and an open position where the needle tip is in a position away form said valve seat, characterized wherein said needle comprises a needle main portion and a separate needle tip portion, said needle main portion including a recess located at its distal end for location of said needle tip portion, and having spring means located between main portion and tip portion, said tip portion adapted to move along said axis relative to said needle main portion, wherein the proximal portion of said needle tip and said recess form a pressure chamber, and wherein the distal end of the needle main portion includes at least one
- the nozzle arrangement may include means to limit the movement of said needle tip away from said main needle body.
- the limiting means may be provided by an internal collar at the end of said recess.
- the said spring is pre-stressed.
- Figure 1 shows the distal end of a fuel injector according to one example
- Figure 2 shows the nozzle arrangement of the figure 1 example in more detail
- Figure 3 illustrates the operational stages of the figure 1 and 2 examples.
- the problem of nozzle seat wear in a common rail system is solved by using a hydraulic suspension needle (HSN) arrangement wherein the (mass of the) needle is divided into two portions, a main portion and a tip portion.
- the tip portion impacts with the seat as normal while the rest of the needle will be gradually slow down by spring force.
- the needle impact momentum is reduced as the mass is less which minimise seat wear.
- Figure 1 shows a schematic view of the distal end of a fuel injector (nozzle capsule) 1 according to one example. It shows a needle upper control chamber 2, where fuel pressure acts to operate the main needle portion 3.
- nozzle capsule fuel injector
- the spring may be positioned within the chamber by a needle tip projectionl4 in the proximal portion of the needle tip portion having a smaller diameter than the tip portion.
- the spring is preferably preloaded
- the needle tip portion includes a widened piston portion 11 dimensioned similar to the diameter of the housing such that it forms generally a seal therewith.
- the needle tip portion can reciprocate like a piston within the chamber 9 formed by the housing/recess in the main body portion.
