Definitions
- the invention relates to a fuel injection valve for the intermittent injection of fuel into the combustion chamber of an internal combustion engine.
- Such fuel injectors are used in fuel injection systems in which fuel is preferably injected directly into combustion chambers of self-igniting high-speed internal combustion engines, the injection occurring under high pressure.
- the fuel is conveyed by a high-pressure fuel pump from a fuel tank, compressed to high pressure and conveyed into a so-called rail, which serves as a reservoir for the compressed fuel. From this high-pressure fuel storage go from several lines that serve to supply the fuel injection valves.
- the fuel injection valves currently used operate on the servo-hydraulic principle, ie they include a nozzle needle, which is arranged longitudinally displaceable in the high-pressure chamber of the fuel injection valve and which opens or closes one or more injection openings by their longitudinal movement.
- the Movement of the nozzle needle and thus the beginning and end of each injection are hydraulically controlled.
- a fuel-filled control room is available.
- the under high pressure fuel exerts pressure on the nozzle needle and pushes them by means of the so impressed hydraulic closing force against a nozzle seat, in which case the pressure is additionally impressed on a needle-closing spring, which already exerts a pressure on the nozzle needle, if not yet hydraulischger pressure
- the pressure exerted on the upper side of the nozzle needle can be lowered by means of a control valve, so that it lifts itself from the nozzle seat into its open position and thus releases the injection opening again.
- Corresponding control valves or control devices are used in the known fuel injection valves in order to open and close the injection valve hydraulically with the required force via the nozzle needle when an electric actuator, for example a piezo or solenoid, is actuated.
- an electric actuator for example a piezo or solenoid
- the electric actuator releases a discharge throttle via a pilot valve.
- the pressure reduction in the control chamber causes the opening of the nozzle needle.
- the pilot valve is closed, the control chamber is filled via an inlet throttle and the nozzle needle closes again.
- an electrical actuator also releases a discharge throttle via a pilot valve.
- the pressure reduction in the control room opens the nozzle needle.
- a generic fuel injection valve is known from EP 1991773 B1.
- a 3/2-way control device is realized.
- the known control device is designed in several parts and has a control valve with a guided in a valve guide valve insert.
- an outlet throttle is arranged, which permanently interconnects the areas of the control room divided by the control valve.
- permanently fuel can be exchanged via the outlet throttle between the two subdivided by the control valve areas of the control chamber.
- Object of the present invention is to develop a generic fuel injection valve such that the hydraulic efficiency in the intermittent injection of the fuel is improved in the combustion chamber and that the opening or closing of the nozzle needle can be done faster compared to the prior art.
- a fuel injection valve for the intermittent injection of fuel into the combustion chamber of an internal combustion engine having a housing which has a high-pressure chamber which communicates with a high-pressure inlet and a low-pressure chamber, furthermore with a nozzle needle which can be moved longitudinally in the high-pressure chamber and which has a nozzle seat cooperates and opens by its longitudinal movement, a compound of the high-pressure chamber with an injection port and closes, wherein the nozzle needle is acted upon by a compression spring with a directed towards the nozzle seat closing force and wherein the compression spring is supported on one side on a spring sleeve in which the nozzle needle is guided in its free end, further with a limited by the spring sleeve and the upper end of the nozzle needle control chamber, which is filled with fuel under pressure and controlled so exerts a closing force on the nozzle needle, also mi t arranged in the control chamber control valve, which divides the control chamber into a
- the interruption of the connection formed by the outlet throttle can be effected by closing the outlet throttle by means of a switching element.
- the switching element consists of a ball arranged in the outlet throttle.
- This can advantageously consist of steel or ceramic.
- the switching element may also be a slider with cone, a cylinder or a plate.
- the respectively provided switching element can be held by a prestressed spring in a sealing seat provided in the outlet throttle.
- the desired switching characteristic can be realized particularly well.
- the second control chamber can be partially limited by a seat plate, which is connected via a controlled closable throttle bore with the low-pressure chamber in combination.
- the throttle bore can be closed via an armature arranged in the low-pressure chamber, wherein the armature can be lifted by an electric actuator against the bias of the spring controlled by the throttle bore.
- This armature represents the so-called pilot valve, via the actuation of which the fuel injection valve is activated.
- the valve insert can be designed mushroom-shaped according to a particularly advantageous embodiment.
- the valve guide further advantageously has an inlet throttle with supply of high-pressure fuel in the second control chamber.
- valve guide can have at least one diagonally arranged bore, via which the first control chamber can be connected to the high-pressure space for supplying high-pressure fuel.
- Particularly advantageous two diagonal or three offset by 120 ° arranged holes are provided.
- valve guide and the valve core can advantageously be guided slowly displaceable in the spring sleeve. As a result, a special compact design is created.
- all pressure chambers have a balanced pressure level, which corresponds to the system pressure, when the pilot valve is closed, that is to say when the throttle bore is closed, while the outlet throttle in the stationary state is blocked at the same time.
- the advantageous mushroom-shaped valve insert is in its lower stop position, so that the two-part control chamber is connected by the open control valve with the high-pressure chamber.
- the switching element which is preferably designed as a ball, closes the connection formed by the outlet throttle between the first control chamber and the second control chamber either by its own gravity or in the embodiment with the compression spring according to spring assisted.
- the pressure drop in the first control chamber reduces the closing force of the nozzle needle on the nozzle seat to the fuel infiltration on the needle seat surface, so that the nozzle needle opens. Then, the nozzle needle performs its opening stroke, which is maintained by the pressure difference between the high-pressure chamber and the control chamber. The nozzle needle would now perform an opening stroke until it abuts the upper needle stop on the valve core.
- this attachment point is designed so that it is never reached in normal operation in engine operation and so has no relevance.
- the armature closes the throttle opening.
- the continuously existing fuel flow from the high-pressure chamber via the inlet throttle ensures the pressure increase in the second control chamber.
- the reversing pressure gradient which now adjusts from the second control chamber to the first control chamber, acts as a closing force on the inventively provided switching element, which is preferably designed as a ball, so that the outlet throttle between the first control chamber and the second control chamber interrupted or blocked becomes.
- the closure of the drain throttle assists in the faster pressure rise in the second control chamber, so that the valve core opens earlier with the switching valve seat and releases a large cross-section for the fuel supply from the high-pressure chamber.
- a rapid opening of the nozzle needle provides for an earlier injection jet structure, resulting in improved combustion in the combustion chamber.
- the faster nozzle needle opening can be used for multiple spray intervals especially for multiple injections.
- the faster closing of the nozzle needle can also be used for shorter spray intervals in multiple injections.
- the drain and inlet throttles can be designed for smaller flows. This, in turn, reduces the fuel flow during the injection via the outlet throttle, so that the hydraulic efficiency of the entire common rail system is improved. A higher hydraulic efficiency also reduces the fuel consumption of an internal combustion engine.
- FIG. 1 shows a longitudinal section through a fuel injection valve according to the invention
- Figure 4 the time course of the injection rate using an injection valve according to the invention in comparison to a conventional injection valve.
- the fuel injection valve comprises a housing 10, which is connected via a nozzle lock nut 12 with a nozzle 14. On the opposite side, the housing 10 is connected via a closure cap 16 with an electrical connection wedge 18. Inside the housing 10, a high-pressure chamber 20 is formed.
- the fuel injection valve is divided into a high-pressure region and a low-pressure region.
- the high pressure region 20 is delimited at its combustion chamber end by a nozzle seat 22.
- a nozzle needle 24 is arranged longitudinally displaceable. This cooperates with the nozzle seat 22 for opening and closing at least one injection opening 26, which is formed facing the combustion chamber in the nozzle 14 together.
- the nozzle needle 24 is guided at its end facing away from the nozzle seat in a spring sleeve 28, wherein a compression spring 32 is arranged under pressure bias between the spring sleeve 28 and a disc 30 placed on a shoulder of the nozzle needle. On the other hand, it presses the spring sleeve 28 against a control valve 34.
- the multi-part control valve 34 is supported on a seat plate 36 from.
- the high-pressure chamber 20 can be filled with high-pressure fuel via a high-pressure connection 25, not illustrated here, which has been compressed by a high-pressure pump (not shown in the drawing).
- This high fuel pressure prevails in the entire high-pressure chamber 20 and causes a hydraulic Force on the nozzle needle 24, which exceeds the force of the closing spring 32 by far.
- the nozzle needle In order to generate a counterforce necessary for the longitudinal movement of the nozzle needle 24, the nozzle needle, with its front side facing away from the nozzle seat, delimits a first control chamber 38, which is bounded laterally by the spring sleeve 28 (see FIG.
- the nozzle needle 24 opposite side of the first control chamber 38 is bounded by the two-part control valve 34.
- This control valve 34 consists of a mushroom-shaped valve insert 40 and an annular valve guide 42. Both the valve insert 40 and the valve guide 42 are each arranged in the spring sleeve 28, as can be seen from Figure 3a.
- the valve insert 40 is guided longitudinally displaceable in the valve guide 42.
- the valve guide 42 rests against the seat plate 36 and, together with the valve insert 40 and the valve guide 42, surrounds a second control chamber 44.
- This second control chamber 44 opens into a throttle bore 46 which can be closed by an armature 48 (see FIG. b, c).
- the armature is located on the low pressure side of the fuel injection valve, as shown in FIG. From the throttle bore 46 escaping fuel is discharged from the housing 10 in the low pressure region via a leak oil connection, also not shown here.
- the armature 48 is acted upon by a spring 50 in the direction of the throttle bore 46. In the stationary state, the armature 48 closes the throttle bore tightly due to the spring force of the compression spring 50. Against the spring force of the compression spring 50, the armature 48 can be lifted by an electromagnet from the throttle bore 46.
- control valve 34 is designed in two parts in the embodiment shown here. It consists of the mushroom-shaped valve insert 40. This has a bore 54, as shown in Figure 3.
- the valve guide in which the valve insert is guided longitudinally displaceable, has an inlet throttle 56 and an outlet throttle 58.
- the inlet throttle connects the high-pressure chamber 20 with the second control chamber 44.
- the outlet throttle 58 connects The outlet valve 58 can be closed by a ball 60 (see in particular Figures 2 and 3).
- the valve guide 42 also has two diagonally opposite diametrically opposite ones Holes 62 through which fuel can flow.
- the function of the fuel injection valve according to the invention is as follows.
- the armature 48 closes in the de-energized state of the electromagnet 52, the throttle bore 46 of the seat plate 36 and prevents leakage of fuel from the second control chamber 44 in the leakage area, ie the area in the low pressure part of the fuel injection valve.
- the seat plate 36 is pressed against the housing 10 (see Figure 1). Due to the high surface quality and flatness of the support surface hereby a radial seal between the high pressure and the low pressure area (leakage area) and between the high pressure area and the second control chamber 44 is provided. This avoids permanent leakage.
- the armature 48 is lifted from the throttle bore 46, so that fuel flows through the throttle bore 46 of the seat plate 36 from the second control chamber 44 in the low pressure region and thus generates a pressure drop in the second control chamber 44.
- the pressure drop creates a pressure difference between the second control chamber 44 and the first control chamber 38.
- the first control chamber 38 is disconnected from the second control chamber 44 immediately.
- the pressure difference between the first and the second control chamber is due to the fuel flowing in via the inlet throttle 56 of the valve guide 42 from the high-pressure region without further losses by a flow into the first control chamber 38 (see Fig. 3b).
- the valve insert 40 is pressed down earlier against the spring sleeve 28 in this control valve 34 according to the invention by the faster pressure build-up in the second control chamber 44.
- the inlet bores 62 of the valve guide 42 are released and the first control chamber 38 is suddenly filled with fuel from the high-pressure region (FIG. 3 c).
- the same pressure level as in the high-pressure region 20 arises in the second control chamber 44 as well as in the first control chamber 38.
- the nozzle needle 24 is pressed by the applied pressure in the first control chamber 38 and additionally supported by the force of the compression spring 32 back into the nozzle seat 22 and thus terminates the injection into the combustion chamber, not shown here.
- FIG. 2 clearly shows the closed position of the ball 60, in which the outlet throttle 35 is closed.
- the ball 60 closes due to gravity.
- the ball can additionally be supported by a spring, not shown.
- the illustration according to FIG. 2b shows the ball 60 in the lifted position.
- the ball 60 is moved away from the outlet throttle 58, so that the outlet throttle 58 is released.
- the time profile of the injection rate according to the present invention curve I
- the time profile of the injection rate according to the prior art curve II
- the difference is that according to the prior art, the outlet throttle 58 is not closed by a ball 60, so that in each state fuel can flow through the outlet throttle.
