Definitions

  • Injectors of the type described in the introduction are frequently used in common-rail injection systems. Injectors for common rail systems for injecting high viscosity fuels into the combustion chamber of internal combustion engines are known in various forms. In the case of heavy oil, heating up to 150 ° C is required to achieve the necessary injection viscosity.
  • an injector for a common-rail injection system has different parts, which are usually held together by a nozzle clamping nut.
  • the actual injector nozzle contains a nozzle needle, which is guided axially displaceably in the nozzle body of the injector nozzle and has a plurality of open spaces through which fuel can flow from the nozzle antechamber to the needle tip.
  • the nozzle needle itself carries a collar on which a compression spring is supported, and immersed in a control chamber, which can be acted upon with fuel under pressure.
  • To this control room can an inlet channel via a T2011 / 000031
  • the pressure in the control chamber can be controlled by a control valve, which is usually actuated by an electromagnet. With appropriate wiring, an opening of the solenoid valve can cause a flow of fuel through a throttle, so that a decrease in the hydraulic holding force leads to the immersed into the control chamber end face of the nozzle needle for opening the nozzle needle. In this way, the fuel can pass through the injection openings in the combustion chamber of the engine in the sequence.
  • an inlet throttle is usually also provided, wherein the opening speed of the nozzle needle is determined by the flow difference between the inlet and outlet throttle.
  • a subset of the fuel is therefore taken between the prefeed pump and the high-pressure pump of the injection system, passed through a heat exchanger and fed as flushing through a separate channel in the injector to the control valve, so that the purge flows through the armature chamber of the control valve and thus keeps at a certain elevated temperature.
  • the injectors which are to be used in accordance with WO 2009/023887, operate on the common rail principle, in which in a common high-pressure fuel storage, the common rail, fuel is kept under high pressure, the injectors via high pressure lines with the Common rail are connected and it comes after actuation of the control valve in the respective injector to a lifting of the nozzle needle from the valve seat and thus to an injection into the combustion chamber, wherein the corresponding injection quantity is provided from the common rail.
  • Diameter is significantly increased compared to the high pressure lines, so that from the high pressure fuel storage a certain amount of injection can be delivered without causing an immediate pressure drop, as would be the case if the injection amount would be taken from a common high pressure line.
  • the injection quantity falls in such pressure-controlled injectors nor to a control amount, which is discharged through the open control valve, which controls the pressure in the control chamber at the end remote from the injectors end of the control needle in the low pressure region.
  • the high-pressure pumps rest, and the pressure in the system falls below the prefeed pressure of the prefeed pump, so that the pressure of the prefeed pump is sufficient to pump fuel into the high-pressure fuel storage.
  • the fuel provided for this purpose is inventively taken between the prefeed pump and the high-pressure pump, heated in a heat exchanger and fed directly to the high-pressure fuel storage.
  • the high pressure fuel storage represents a relatively large volume inside the injector, so that the entire injector is heated sufficiently when the high pressure fuel storage is maintained at an appropriate temperature.
  • the procedure is preferably such that the flushing quantity is discharged from the injector via connections for high-pressure fuel lines of the injection.
  • the high-pressure fuel lines which, as already mentioned, are not under high pressure when the internal combustion engine is at rest, are optionally connected to the low-pressure region of the injection system in internal combustion engines with a modular design, with the interposition of a manifold, so that the flushing quantities can be removed via these lines.
  • the procedure is preferably such that the flushing quantity is returned to the tank or to the prefeed pump, so that here too a corresponding temperature level can be maintained in order to prevent clogging of lines in this area.
  • the method according to the invention therefore further developed such that the supply line for the flushing quantity to the high-pressure fuel storage is closed by a check valve during operation of the internal combustion engine.
  • the device for injecting fuel into the combustion chamber of an internal combustion engine for carrying out the method according to the invention comprises at least one prefeed pump for conveying fuel from a tank, at least one high-pressure pump and at least one injector, wherein the fuel delivered by the prefeed pump of the high-pressure pump and the high-pressure pump delivered high-pressure fuel is supplied to the injector, inside the injector, a high-pressure fuel storage is arranged and the injector has an injection nozzle with an axially displaceable nozzle nozzle in a front nozzle needle, which dips into a high-pressure fuel feedable control chamber whose pressure on at least one or Drain channel for fuel opening or closing control valve is controlled.
  • the branch line passes through a heat exchanger and flows into the high-pressure fuel storage of the injector, so that it is flowed through by the flushing.
  • the device according to the present invention is preferably further developed such that low-pressure lines are arranged for the return of the flushing amount to the prefeed pump.
  • Control valve for controlling the flushing amount is arranged in the branch line.
  • the injector is made particularly large, it may be advantageous not only to temper the high-pressure accumulator with a flushing quantity, but also to heat the low-pressure side of the injector.
  • the device according to the invention can be further developed in such a way that a connection directly connected to the control valve of the injector for a further flushing quantity is arranged on the injector.
  • the device according to the invention can be developed with advantage in that in the branch line for the flushing amount, a check valve is arranged, which is opposite Supply direction for the flushing closes.
  • a check valve is arranged, which is opposite Supply direction for the flushing closes.
  • a schematically illustrated non-return valve 13 is arranged in the region of the mouth of the branch lines 11 in the high-pressure accumulator of the injectors, which closes in the direction of the arrow 16, to prevent a backflow of high-pressure fuel through the branch line 11.
  • a similar valve may also be arranged in the T-piece 8.
  • the actual injector nozzle contains, as can be seen in Fig.
  • a nozzle needle 16 which is guided axially displaceably in the nozzle body 15 of the injector 9 and a plurality of free surfaces 17, through which 18 can flow fuel to the needle tip from the nozzle antechamber.
  • the nozzle needle 16 itself carries a collar 19, on which a compression spring 20 is supported, and immersed in a control chamber 21, which can be acted upon with fuel under pressure.
  • a control chamber 21 To this control chamber 2 1, an inlet channel 22 via an inlet throttle 23 and a drain channel 24 via an outlet throttle 25 are connected, wherein the respective pressure built up in the control chamber 21 together with the force of the compression spring 20 holds the nozzle needle 16 in the closed position.
  • the pressure in the control chamber 21 is controlled by a control or solenoid valve 26 which is actuated by an electromagnet 27.
