Definitions
- the invention relates to an injection system for an internal combustion engine.
- WO 95/25887 describes a conventional injection system for Internal combustion engines shown, which have a prefeed pump that delivers the fuel from a fuel tank.
- the pre-feed pump then delivers the fuel to one High pressure pump used to inject fuel into the combustion chamber of the internal combustion engine required injection pressure generated and multiple injectors with fuel provided.
- High pressure pumps are usually as Radial piston pumps with multiple pump cylinders that are driven by an eccentric by a drive shaft.
- a volume flow control valve is arranged, which by regulates the fuel flow delivered by the pre-feed pump. After the volume flow control valve, the fuel is on the distributed individual pump cylinder of the high pressure pump.
- the invention has for its object an injection system to create the type described above, with as possible blocking the flushing line with little construction effort enabled during the starting process.
- Valve also called dosing element below
- valve for control of the fuel flow branching off via the flushing line to be designed as a rotary slide valve or the valve for control of the fuel flow branching off via the flushing line to integrate into a distributor element for the high pressure pump, so that on a separate valve to control the purge flow can be dispensed with.
- the distributor element is preferably a rotary slide valve with a rotatable part that mechanically with the drive shaft the high pressure pump is coupled and that of the Pre-feed pump delivered fuel depending on Angle of rotation of the drive shaft on the individual pump cylinders the high pressure pump.
- the control of the fuel flow diverted via the purge line takes place here by an axial displacement of a part of the rotary valve, with a further flow opening in Dependence on the axial position of the displaceable Partially released or sealed.
- the rotary slide valve preferably has an axially displaceable one Sleeve and a rotatably mounted in the sleeve relative to this Shaft on, in the outer surface of the sleeve in one arranged a first throughflow opening in the first axial region which is the fuel flow from the prefeed pump too the individual pump cylinders of the high pressure pump predetermined angular positions of the shaft relative to the sleeve releases while a second in a second axial area Flow opening is arranged, which over the flush line branching fuel flow depending on the controls axial position of the sleeve relative to the shaft.
- shaft, sliding sleeve and housing can be a combination of the same way Housing, sleeve and sliding shaft, or a combination Shaft, sleeve and housing are used in which at least two of the components are movable relative to one another (slidable and / or rotatable).
- shafts and / or sleeves and / or housings instead of of shafts and / or sleeves and / or housings also conical, disk-shaped or shaped in any other suitable manner Body are used
- the injection system shown in Figure 1 is used for injection of fuel into the combustion chambers of an internal combustion engine with four cylinders.
- the injection system has a prefeed pump 1, which first remove the fuel via a fuel filter 2 promotes a fuel tank 3.
- the pre-feed pump 1 then directs the fuel a high-pressure pump 4, which for injection into the Combustion chambers of the internal combustion engine require injection pressure generated and in a conventional manner as a radial piston pump is carried out with three pump cylinders, in the drawing for simplification only one pump cylinder 5 with one pump piston 6 is shown.
- the mechanical drive of the pump piston 6 takes place via a drive shaft 7, which has an eccentric 8 carries.
- the pump cylinders are used to control the pumping process 5 each have an inlet valve 9 and an outlet valve 10 on, both of which are designed as check valves and therefore work independently.
- a distributor element 11 is arranged, the of the feed pump 1 delivered fuel flow to the three Pump cylinder of the high pressure pump 4 distributed.
- the three pump cylinders are arranged at 120 ° to each other so that also the suction phases of the individual pump cylinders in time are offset from one another.
- the distributor element 11 is designed as a rotary valve and consists essentially from a hollow cylindrical housing 12, one in the housing 12 axially displaceable, also hollow cylindrical Sleeve 13 and the drive shaft 7 of the high pressure pump 4, the led out of the housing of the high pressure pump 4 and in the Sleeve 13 is rotatably arranged.
- the supply of the fuel delivered by the prefeed pump 1 to the distributor element 11 takes place through a channel 14, which runs centrally in the drive shaft 7 and into a radially to the drive shaft 7 extending bore 15 opens in an axially extending groove 16 in the outer surface of the drive shaft 7 merges as shown in FIG. 2b Representation of the lateral surface of the drive shaft 7 can be seen is, the arrow P1 in Figure 2b, the direction of rotation of the drive shaft 7 reproduces.
- the delivered by the pre-feed pump 1 Fuel therefore enters the bore via the channel 14 15 and finally in the groove 16.
- the sleeve 13 accordingly has a slot-shaped throughflow opening 17 on, in the outer surface of the sleeve 13 in at an angle of approximately 45 ° to the longitudinal axis of the sleeve 13 runs, the axial extension D1 of the slot-shaped Flow opening 17 is less than the axial extent D2 of the groove 16 in the lateral surface of the drive shaft 7, such as from the representation of the outer surface of the sleeve 13 or Drive shaft 7 can be seen in Figures 2a and 2b.
- the hollow cylindrical housing 12 has on the inside the wall a circumferential over the entire circumference Ring groove 18, in which at one point a radially extending Bore 19 opens out to an outlet of the distributor element 11 forms and with the inlet valve 9 of the associated pump cylinder 5 is connected.
- An axial region 20 shown in the drawing enables So a speed-synchronous control one at a time Pump cylinder 5, so that for a three-cylinder high-pressure pump 4 corresponding to three such axial areas in a row must be arranged.
- a rotation of the drive shaft 7 thus leads to a certain one Angular range of the drive shaft 7 to an overlap the groove arranged in the lateral surface of the drive shaft 7 16 and the slot-shaped flow opening 17 in the sleeve 13, so that the fuel in this angular range of the drive shaft 7 via the channel 14, the tap hole 15, the axial extending groove 16, the oblique throughflow opening 17 in the circumferential annular groove 18 and from there on radial branch bore 19 to the inlet valve 9 of the high pressure pump 4 can reach, which determines the duration of the suction phase is. Outside this angular range, however, seals the sleeve 13 the axially extending groove 16 in the lateral surface the drive shaft 7, so that no fuel to the intake valve 9 of the high pressure pump 4 arrives.
- the duration of the suction phase is influenced lets by axially displacing the sleeve 13 what by an electromagnetic or other actuator, which is not shown for simplicity.
- the overlap begins the groove 16 with the flow opening 17 at the same angular position on, but the overlap ends with an earlier one Angle, which means the duration of the suction phase of the corresponding Pump cylinder is shortened.
- the time of the Beginning of the overlap regardless of the axial position the sleeve 13 is essentially the same for each suction phase, wherein the beginning of the overlap preferably at the top Dead center of the respective pump cylinder 5, which is the beginning of Suction phase of the pump cylinder 5 corresponds. This will Pressure waves at the beginning of the suction phase due to sudden filling a suction vacuum with fuel avoided.
- the fuel flow delivered by the high pressure pump 4 becomes then fed to a pressure accumulator 21 (Common Rail), from which four injectors are supplied with fuel, whereby the injectors are designed in a conventional manner and for simplification are not shown.
- a pressure accumulator 21 Common Rail
- a pressure control valve can be arranged that when exceeded a predetermined maximum pressure on the outlet side the high pressure pump 4 part of the fuel flow branches and returns to the fuel tank 3 until the fuel pressure back to the specified maximum pressure has dropped.
- the pressure control valve and the return in however, the fuel tank 3 is in the drawing for simplification not shown.
- the distributor element 11 enables in addition to that described above Distribution of the feed pump 1 Fuel on the pump cylinder 5 of the high pressure pump 4th also control of the fuel flow through the purge line 22.
- the pressure build-up can be started when the engine is started accelerate by flushing line 22 during the starting process when the distributor element to maximum Suction length is set, is blocked.
- the Sleeve 13 has an axially directed, slot-shaped flow opening 26 on.
- a radially extending bore 27 from which the fuel diverted via the purge line 22 is guided into the housing of the high pressure pump 4 to flush the high pressure pump 4 with fuel, which is cooling and lubrication of the high pressure pump 4 causes. Subsequently the fuel used for flushing purposes leaves the housing the high pressure pump 4 and is via the return line 23 returned to the fuel tank 3.
- the sleeve 13 then by the electromagnetic actuator in Figure 2a pushed to the right until the flow opening 26 the annular groove 25 overlaps, as shown in Figure 1. In this position reaches part of the delivered by the pre-feed pump 1 Fuel over the channel 14, the bore 24, the annular groove 25, the flow opening 26 and the bore 27 in the flushing line 22 and finally in the housing of the high pressure pump 4.
- the fuel flows through the purge line 13 to High pressure pump 4 regardless of the axial position of the sleeve 13, the duration (suction phase) of the fuel inflow to Input of the high pressure pump 4 controls. Only in the starting phase the axial position of the sleeve 13 is adjusted so that at maximum delivery rate to the input of the high pressure pump 4 Fuel flow through the purge line 13 is interrupted.
- the sleeve 13 is preferably by a not shown Spring element biased to the right in the direction of arrow P2, so that the sleeve 13 in the event of actuator failure is pushed to the right, which releases the purge flow but also shortened the suction phase to a certain minimum value becomes. This ensures that a failure of the actuator does not result in permanent flushing failure or too high a flow and thus too high Pressure leads.
- the sleeve and the annular groove 25 in the drive shaft 7 are preferred designed so that when the flow opening overlaps 17 with the groove 16 and the flow opening 26 with the Ring groove 25 of the drive shaft 7 is only an insignificant throttling of fuel flow occurs and therefore less Fuel pressure is adjustable, which reduces the power loss reduced and a smaller one, for example in the tank 1 arranged, electrically operated feed pump 1 used can be.
- FIG. 3 finally shows the outer surface of the sleeve 13 in developed state with an alternative version of the Flow opening 26 in the sleeve 13.
- the flow opening 26 is wedge-shaped in the direction of the Annular groove 25 of the drive shaft 7 so that the flush line 22 branched fuel flow with an axial displacement the sleeve 13 is released continuously.
- An axial Displacement of the sleeve 13 in the direction of the arrow thus leads to this arrangement of the flow openings 17 and 26 into one Shortening the duration of the suction phase of the individual pump cylinders 5 with constant suction start and a stepless one Increase in the flushing current in the flushing line 22.
- the wedge-shaped flow opening 26 in connection with the Ring groove 25 partially throttling the purge flow.
- slot-shaped tapers Passage opening 17 at its in the direction of the passage opening 26 lying end wedge-shaped, which at the end of one Suction phase of the fuel flow to the individual pump cylinders 5 is continuously reduced to zero.
- Wedge-shaped flow openings 17, 26 are advantageous abrupt changes in the amount of fuel flow decreased and thus pressure waves in the fuel lines are avoided.
- the course of the flow opening For example, be designed so that the throttling Cross section of the flow opening 26 in the axial direction increases exponentially, resulting in a correspondingly progressive Response of the flushing when the sleeve 13 is displaced leads.
- the groove 25 in the outer surface of the drive shaft can also 7 run in the axial direction when the Flow opening in the sleeve 13 in a ring over the entire Extent of the sleeve 13 extends, being in the annular In this case, the flow opening is distributed over the circumference several axially extending webs are arranged, or the groove the sleeve does not break completely.
- the shaft 7 are axially displaceable. Can too both the sleeve 13 and the shaft are axially displaceable be, the displacement paths then corresponding to one another are coordinated.
- the invention is not limited in its execution the preferred embodiments given above. Rather, a number of variants are conceivable, which of the solution shown, even if fundamentally different Makes use of explanations.
