Definitions
- the invention relates to a fuel supply system for common rail heavy fuel injection systems for internal combustion engines with a tank, a prefeed pump for conveying heavy oil from the tank to a high-pressure pump, wherein the high-pressure pump is connected via at least one high-pressure line to a high-pressure accumulator (rail), the at least one injection injector feeds, and further with a purge valve, which is connected via its own high-pressure line to the high-pressure accumulator to control at least a subset of the heavy oil via a return line into the tank.
- heavy oil For cost reasons, low-quality fuels such as heavy oil are used in very large diesel engines, especially in marine diesel engines. Due to the special physical properties of heavy oils, special precautions must be taken to operate with heavy oil. For example, the viscosity of heavy fuel oil is much higher than normal diesel fuel, so heating to more than 80 ° C is required to pump the heavy oil at all.
- the high viscosity of heavy fuel oil means that fuel must always be circulated in the piping system during engine standstill in order to prevent the formation of heavy oil in the pipes.
- a purge valve is provided in common-rail heavy fuel injection systems of the type mentioned, which is closed during operation of the engine and thereby the high-pressure side parts of the fuel system and thus the rail against a low-pressure side fuel return line through which fuel into the tank can be returned, closes.
- this flush valve can now be opened so that fuel from the High pressure side is passed through the high pressure lines and the rail through the valve to the low pressure side and subsequently into the tank in the circuit, wherein the fuel is maintained by a preheater at a corresponding temperature, so that a solidification of the heavy oil is prevented in the lines.
- the purge valve In addition to the possibility of generating a circulation flow for controlling the temperature of the fuel in the system, the purge valve also has the function of an emergency stop valve. By suitable control of the purge valve, the system pressure can be lowered very quickly in an emergency, without the injection injectors themselves must be disabled.
- a fuel supply system of the type mentioned in the further developed such that the valve seat of the valve member is designed as a sliding seat.
- the sealing effect is not achieved by pressing a sealing surface on a valve seat, but by an increased overlap length of the sealing surfaces, between which a narrow gap remains.
- small permanent leaks occur. If particles are temporarily trapped between the sealing surfaces, they can lead to damage, but since the sealing effect is due to the narrow gap and the overlap length, this damage does not affect the sealing effect.
- the fuel can be preheated before each feeding into the heavy oil lines, so that the lines and other components can be kept at a corresponding temperature in order to avoid an excessive increase in the viscosity in the downtime of the engine.
- the fuel supply system according to the invention is further developed such that the valve member is guided displaceably in a valve sleeve and having a formed by a return control edge, which is displaceable to open the valve in the region of the radially opening into the valve sleeve high-pressure line and to close the valve the mouth of the high-pressure line to form an overlap of valve member and valve sleeve is displaceable.
- the sealing surfaces arranged on the outer jacket of the valve member and on the inner jacket of the valve sleeve cooperate with one another and have a large overlap length, so that only extremely small leakage quantities occur when the valve is closed.
- valve member is now moved in such a way that the control edge formed by the return passes into the region of the mouth of the high-pressure line and the fuel can flow off over the region of the valve member which is delimited by the control edge and has a smaller diameter.
- an annular flow area is released or increased.
- the size of the recess on the valve member determines the annular Flow cross-section and thus the flow rate, wherein a formation can be made such that the flow rate is sufficient to keep the viscosity of the heavy oil in the lines correspondingly low.
- the invention can be further developed according to a preferred embodiment in that the high-pressure line opens into an annular groove of the valve sleeve.
- a retraction of the valve member in the region of the high-pressure line opening radially into the valve sleeve leads directly to a relatively large flow rate.
- the fuel supply system according to the invention is further developed such that the maximum coverage corresponds to at least 0.1 to 0.5 times the valve member diameter, so that the invention desired insensitivity of the purge valve can be achieved against wear by choosing a sufficiently large overlap length of the sealing surfaces ,
- the invention is developed to the effect that the actuating means are designed as pneumatic means, so that the hitherto used reaching actuation systems for flushing valves can also be used in the flush valves according to the invention, in a particularly simple manner, the invention is further developed such that a With pressurized medium, in particular compressed air, can be acted upon line in a limited by a transverse to the direction of displacement surface of the valve member space.
- the transverse to the direction of displacement surface of the valve member forms in a suitable cylinder from a piston which can be moved by the pressure of the injected pressure medium against the force of a spring, whereby the actuation of the valve member is triggered.
- a pressure spring acting on the valve member in the closing direction is advantageously provided.
- the fuel supply system according to the invention is developed with advantage to the effect that a control device is provided which cooperates with the purge valve to open the valve when the internal combustion engine.
- FIG. 1 a fuel supply system according to the invention
- Fig. 2 a section through a flush valve according to the prior art
- Fig. 3 a flush valve of the fuel supply system according to the invention.
- Fig. 1 is a common rail heavy fuel injection system shown schematically. From the tank 1 is supplied by a prefeed pump 3 fuel, which was heated in the preheater 2, via a fuel filter 4 and fuel lines 11 at least one high-pressure pump 5, where the fuel is compressed to system pressures of higher than 1400 bar. The compressed fuel passes through high pressure lines 12 in at least one rail 6, which is equipped inter alia with at least one pressure relief valve 13 and a rail pressure sensor 7. The pressure in the rail 6 is set by the control unit 10 by regulating the amount of fuel delivered by the high-pressure pump 5 into the high-pressure line 12. Starting from the rail 6, the fuel passes via a flow restrictor 18 via the high-pressure line 14 into the injection injector 8, which is likewise controlled by the control unit 10.
- the fuel control amount required for the function of the injection injector 8 passes back into the tank 1 via the low-pressure lines 17.
- a further high-pressure line 15 leads from the rail 6 to a flushing valve 9 , which is controlled by the control unit 10, a subset of the fuel directly in low pressure lines 16 can abgresn that lead directly back to the tank 1.
- Fig. 2 shows a section through a flush valve 9 according to the prior art.
- the flush valve consists of a body 20, a valve sleeve 23, a valve member 28, a housing 30, a spring 25 and a cover 24.
- a compressed air connection 27 is provided, which with the pressure chamber 31 formed by the housing 30 and piston 26 in Connection is and is sealed to the valve sleeve 23 out with an O-ring 26. If there is no pressure at the compressed-air connection 27, then the spring 25, which is supported on the cover 24 firmly connected to the housing 30 and on the piston 26, pushes the valve member 28 into the valve seat 29 formed in the valve sleeve 23.
- Fig. 3 shows the fuel supply system according to the invention.
- the valve 9 is designed in the form of a sliding seat valve.
- the valve member 28 has a control edge 33 which, in cooperation with the control edge 32 arranged in the valve sleeve 23, releases or blocks the flow through the valve.
- the spring 25 presses the valve member 28 against the housing 30 so that only a minimal gap remains between the valve sleeve 23 and valve member 28, which allows a small amount of leakage.
- the pressure chamber 31 is acted upon by the compressed air line 27 with compressed air, the air pressure pushes the valve member 28 in the direction of the cover 24.
- the control edge 33 on the valve member 28 the control edge 32 of the valve sleeve 23 passes, a significantly larger flow cross-section is released and the Abêtmenge increases sharply at.
