Definitions
- the invention relates to a high-pressure fuel pump for an internal combustion engine according to the preamble of claim 1.
- Direct-injection high-pressure fuel pumps usually have a low-pressure range and a high-pressure range.
- An electric prefeed pump delivers the fuel from a tank into the low-pressure region, from which the fuel is conveyed via the high-pressure fuel pump into a fuel collecting line ("common RaN") connected to the high-pressure region.
- the pressure in the fuel rail is usually controlled by a pressure control and / or a quantity control valve, the valves u.a. be controlled by an evaluation of signals from a pressure sensor of a control and / or regulating device.
- the pressure control valve can also work mechanically.
- the object of the invention is to provide or further develop a fuel high-pressure pump for an internal combustion engine of the type mentioned, which works reliably and is compact.
- the fuel high-pressure pump should be inexpensive.
- the object is achieved by a high-pressure fuel pump for an internal combustion engine with the features of claim 1.
- the known external dimensions of the high-pressure fuel pump can be maintained. Additional hydraulic lines are not required. This advantageously leads to a very compact construction of the high-pressure fuel pump. Due to the omission of the quantity control of the fuel, the high-pressure fuel pump also requires no quantity control valve with an associated output stage and an electrical control line. Furthermore, the pressure sensor necessary for an electronic control can be dispensed with. This makes the invention particularly cost effective and also saves engine power. Since the unnecessary amount of fuel is diverted to the low pressure range, a pressure limiting function is guaranteed.
- the present invention is based on the idea that when using a less pressure-sensitive fuel system in an internal combustion engine, for example, a constant pressure system, can be dispensed with a complex electronic quantity control of fuel.
- the pressure control in the high pressure area is carried out in this condition then via a mechanical pressure control device which is integrated into the high-pressure pump.
- the pressure control device is arranged hydraulically between the low-pressure region and the high-pressure region.
- the unused amount of fuel from the high pressure area is returned to the low pressure area.
- an at least substantially constant pressure on the high-pressure side arises during operation of the internal combustion engine.
- the mechanical pressure control device comprises a mechanical pressure control valve, in particular a mechanical, for example, spring-loaded check valve.
- Mechanical pressure control valves are relatively simple, reliable and therefore inexpensive. This especially applies to check valves. Such also builds extremely small and is therefore easily integrated into the high-pressure fuel pump.
- the throttle may be formed as a separate throttle element or other Querschnitssverengung in a high-pressure side inlet channel, a valve seat body or a receiving opening in the pump housing.
- the pressure control valve is arranged eccentrically in the pump housing of the high-pressure fuel pump in a bore, and that optionally also a connection bore from the pressure regulating valve to the high-pressure region is arranged eccentrically.
- the central central region in the pump housing is known to be reserved for the actual pump functions of the high-pressure fuel pump. In the off-center area, however, there is enough room to integrate the pressure control function. This makes the high-pressure fuel pump to a very effective and compact structure. In addition, this makes the machining of the pump housing easier
- a limit pressure in the high-pressure region is established by a valve spring and / or a sealing diameter between valve element and valve seat of the pressure regulating device.
- the pressure control device has a cartridge-like valve housing.
- the pressure control device can be manufactured and adjusted as a separate module and then added to the pump housing and, for example, held by a pressure between the sleeve and the pump housing.
- the adjustment of the function of the pressure control valve is easier because among other things, with a hydraulic adjustment of the opening pressure, the pump housing does not have to be cleaned for further assembly steps.
- the pump housing is a committee part. It is also advantageous if the inlet valve is arranged coaxially with the pump piston of the high-pressure fuel pump.
- Figure 1 is a schematic representation of a fuel system with a high-pressure fuel pump
- Figure 2 is a perspective view of the high-pressure fuel pump of Figure 1;
- FIG. 3 shows a partial longitudinal section through the high-pressure fuel pump from FIG. 1 with a cut inlet region
- FIG. 4 shows a longitudinal section of the high-pressure fuel pump from FIG. 1 with a cut outlet region
- Figure 5 is a longitudinal section of the high-pressure fuel pump of Figure 1 with a cut pressure control valve (sectional plane V-V in Figure 6).
- FIG. 6 shows a cross section through the high-pressure fuel pump from FIG. 1;
- FIG. 7 shows a representation similar to FIG. 5 of a variant of the high-pressure fuel pump from FIG. 2.
- FIG. 1 shows a schematic representation of a fuel system 8 for an internal combustion engine (not shown) with a fuel High-pressure pump 10.
- the fuel system is, as will be explained, divided into a low-pressure region 12 shown on the left in FIG. 1 and a high-pressure region 14 shown on the right-hand side.
- a pre-feed pump 16 arranged in the low-pressure region 12 pumps fuel from a fuel reservoir 18 via a low-pressure line 20 with a prefeed pressure to an inlet connection 22 of the high-pressure fuel pump 10.
- a filter 24 and a pressure damper 26 are arranged in the low-pressure region 12.
- the pressure damper 26 dampens pulsations arising in the high-pressure fuel pump 10 on the low-pressure side and ensures a high delivery rate even with high numbers of rotations and cams.
- the fuel is sucked into a working space 30 of the high-pressure fuel pump 10.
- the volume of the working space 30 depends on the position of a pump piston 32 in a pump cylinder 34.
- the working space 30 is increased, whereby fuel is sucked.
- the fuel is highly compressed and conveyed via an outlet valve 36 and an outlet connection 38 belonging to the high-pressure region 14 via a high-pressure line 40 into a rail 42.
- injectors 44 are connected, which inject the fuel directly into combustion chambers 46 of the internal combustion engine.
- the pump piston 32 is driven by a cam 48, which is driven by the internal combustion engine - for example via a cam or crankshaft (not shown).
- the cam 48 may also be part of the cam or crankshaft.
- a piston leakage, which arises in the gap between the pump piston 32 and the pump cylinder 34 is returned via a return line 52 in the low pressure region 12.
- FIG. 2 shows the high-pressure fuel pump 10 in a perspective view.
- the inlet connection 22 (low-pressure region 12) and the outlet connection 38 (high-pressure region 14) are arranged on a pump housing 58.
- a filter 64 is integrated in the inlet pipe 22 in the inlet pipe 22.
- the high-pressure fuel pump 10 includes an inwardly dented cover 66 and a flange 68 for attaching the high-pressure fuel pump 10, for example, to a cylinder head of the internal combustion engine. Both parts 66 and 68 are fixedly connected to the pump housing 58.
- the pump piston 32 projects out of the pump housing 58 down.
- a piston spring 70 is supported on the one hand on a spring plate 72 which is fixedly connected to the pump piston 32, and on the other hand (not visible) on the pump housing 58 from.
- the force of the piston spring 70 is thus introduced via the spring plate 72 in the pump piston 32. This ensures during operation that the pump piston 32 always follows the cam contour.
- the inlet port 22 is connected to the filter 64 via a to a longitudinal axis 73 of the pump housing 58 eccentric bore 74 with a lying below the cover 66 receiving space (no reference numeral) for the pressure damper 26.
- the receiving space is in turn connectable to the pump working chamber 30 via two bore sections 78 and 80 coaxial with the pump housing 58 and the inlet valve 28.
- the pump piston 32 is displaceably mounted in a cylinder liner 82. During a suction phase of the pump piston 32, the fuel passes through the bores 78 and 80 and the inlet valve 28 into the pump working space 30.
- the pump working chamber 30 and the outlet valve 36 are hydraulically connected to one another via a bore 88 in the pump housing 58.
- the pressure control valve 54 is arranged eccentrically in the pump housing 58 in a bore 90 in parallel to the longitudinal axis 73.
- the sectional plane of Figure 5 is therefore not centered, but is spaced from the longitudinal axis 73.
- High pressure side the pressure regulating valve 54 is connected via a spaced from the longitudinal axis 73 bore 92 with the outlet valve 36.
- the pressure regulating valve 54 is connected via the bore 90 with the receiving space for the pressure damper 26.
- the pressure regulating valve 54 includes a valve seat (not numbered) on a valve seat body 94 with an inlet bore 95, a ball valve body 96, a spring guide 98, a valve spring 100 and a spring holder 102nd
- valve seat body 94 is firmly anchored, for example via a pressure in the bore 90.
- the valve spring 100 pushes the valve body 96 into the valve seat.
- the valve body is spherical.
- the valve spring 100 is supported on the spring holder 102 from.
- the spring holder 102 is in turn firmly anchored in the bore 90 (for example via a pressure).
- the opening pressure is set via the press-in path of the spring holder 102.
- the high-pressure fuel pump 10 operates as follows: During a downward movement of the pump piston 32 ("suction stroke"), fuel is injected via the inlet valve 28 into the working space 30. During an upward movement (“delivery stroke”), the fuel in the working space 30 is compressed and conveyed via the outlet valve 36 into the high-pressure line 40. Exceeds the pressure in the high pressure region 14, the limit pressure of the pressure control valve 54, this opens by the valve body 96 lifts off the valve seat, so that fuel can flow into the receiving space of the pressure damper 26 and thus in the low pressure region 12. If the pressure in the high-pressure region 14 drops below the limiting pressure of the pressure regulating valve 54, this closes again. In this way, the pressure in the high-pressure region 14 is kept substantially constant, namely at the limit pressure or opening pressure of the pressure regulating valve 54.
- FIG. 7 shows a variant of the high-pressure fuel pump 10. It is true that such
- the pressure regulating valve 54 is realized as a cartridge solution.
- the assembly of the pressure control valve 54 and the setting of the opening pressure can be done outside of the pump housing 58 here.
- the valve seat body 94 is inserted into a sleeve 104 and held, for example via a pressure.
- the spring guide 98 and the valve spring 100 and the spring holder 102 is inserted into the sleeve 104. Again, the spring force and thus the opening pressure is adjusted by the position of the spring holder 102.
- the spring holder 102 can, as shown in Figure 7, are screwed into the sleeve 104. As an alternative to the screw solution, pressing is also possible.
- the pressure regulating valve 54 is mounted and is set, it is assembled as an assembly in the pump housing 58 and held for example via a pressure between the sleeve 104 and the pump housing 58.
- a throttle 56 is also positioned in the bore 92. It is also conceivable to arrange the throttle 56 in the bore 90. As an alternative to the throttle 56, the inlet bore 95 can also have a reduced cross-section in some areas in the valve seat body 94, as a result of which a throttling function is likewise achieved.
