Definitions
- the invention relates to a fuel injection system for internal combustion engines, with a high-pressure fuel pump, with a common rail, with at least one injector, with a prefeed pump, the high-pressure fuel pump supplying the fuel or the injectors with fuel via the common rail, with regulation of the feed pressure of the prefeed pump , with a return line for the removal of fuel from the injector or injectors and / or the high-pressure fuel pump and with a pressure control in the return line.
- the invention has for its object a pressure control to be provided in the return line with improved control quality.
- a fuel injection system for internal combustion engines with a high-pressure fuel pump, with a common rail, with at least one injector, with a prefeed pump, the high-pressure fuel pump de (h or supplying the injectors with fuel via the common rail, with a prefeed pump which feeds fuel from a tank to the fuel ochtikpumpe promotes, with a regulation of the conveying pressure of the prefeed pump, with a return line for removal 'of fuel to or from the high pressure fuel pump to the injectors and / or the Kraf and with a pressure regulation in the return line and the pressure in the return line is regulated depending on the delivery pressure of the feed pump.
- the pressure maintenance in the return line is improved in that the feed pressure pre-feed pump is used as a reference value for the pressure control of the return line. Since the feed pressure of the pre-feed pump is regulated, the control quality of the pressure in the return line is also improved.
- the delivery pressure of the prefeed pump is regulated to an absolute value, so that the regulation .
- the pressure in the return line is independent of the ambient pressure and thus a further improvement in the control quality is achieved.
- the prefeed pump is arranged in the tank, and that a tank jet pump in the tank for filling a swell pot is provided, and that the tank jet pump is driven by the return line.
- the pre-feed pump is driven independently of the high-pressure fuel pump and can therefore be better regulated.
- the pressure in the pressure range of the pre-feed pump is better kept constant, which has an advantageous effect on the control quality of the pressure in the return line.
- the pressure control valve has at least one inlet, one outlet and one control pressure connection and the control pressure connection is hydraulically connected to the pressure side of the pre-feed pump, so that the control quality of the pressure in the return line is improved in the manner according to the invention.
- the pressure control valve is designed as a slide valve, that one end face of the slide valve is acted upon by the delivery pressure of the prefeed pump, that the pressure of the return line and the force of a control spring act on a second end face of the slide valve, and that in Depending on the position of the slide, the discharge of the pressure control valve is released, so that the pressure in the return line is regulated in a simple manner. Because of the sensitive response behavior of slide valves, the control quality is particularly high.
- the pressure control valve is designed as a seat valve with a membrane and a valve body, that the delivery pressure of the pre-feed pump is applied to a first side of the membrane, that the pressure of the return line and the Act by force of a control spring and that depending on the Position of the membrane of the valve body for a valve seat is lifted and the drain of the pressure control valve is released, so that even the smallest pressure changes trigger a control process due to the size of the membrane and thus a high control quality is achieved.
- valve body can be designed as a ball or valve cone, so that the specific advantages of these valve bodies can also be used for a fuel injection system according to the invention.
- Figure 1 shows a first embodiment of a fuel injection system according to the invention in the rest position
- Figure 2 shows the embodiment of Figure 1 in the regular position
- FIG. 3 shows a second exemplary embodiment of a fuel injection system according to the invention.
- FIG. 4 shows a pressure control valve designed as a diaphragm valve.
- FIG. 1 a first embodiment of a fuel injection system according to the invention is shown schematically.
- a high pressure fuel pump 1 that is not Fuel in a common rail 3 is explained in more detail.
- Injectors (not shown) are supplied with fuel from the common rail 3 via connecting lines 5.
- the pressure in the common rail 3 is regulated via a pressure maintaining valve 7.
- the high-pressure fuel pump 1 is supplied with fuel from a tank 9 with a swell pot 11, a plurality of tank jet pumps 13, a prefilter 15, a check valve 17 and an electric prefeed pump 19 via a supply line 21.
- a fuel filter 23 with a water separator and an absolute pressure sensor 25 are installed in the supply line 21.
- the measured values of the absolute pressure sensor 25 are transmitted to a control unit (not shown) which, depending on the pressure measured in the supply line 21, controls the prefeed pump 19 such that a constant absolute pressure prevails in the supply line 21.
- the supply line 21 is supplied with the delivery pressure of the prefeed pump 19.
- the tank jet pumps 13 are driven by the fuel which flows back into the tank 9 via a return line 27 from the common rail 3 and the leakage lines 29 of the injectors (not shown).
- the return line 27 is divided by a pressure control valve 31 into two sections 27a and 27b.
- the pressure in section 27a of the return line 27 is constant.
- the pressure control valve 31 is designed as a slide valve.
- a slide 33 is on its first end face 35 via a connecting line 37 with the pressure in the supply line 21, which is the delivery pressure of the pre-feed pump . 19 corresponds to applied.
- the Connection line 37 opens into a control pressure connection of the pressure control valve 31.
- an inlet 41 is provided, into which the section 27a of the return line opens.
- a second end face 43 of the slide 33 is acted upon by the pressure of the fuel in the section 27a of the return line 27.
- the force of a control spring 45 which is supported against the second end face 43 and the housing of the pressure control valve 31, acts on the second end face 43.
- the pressure in section 27a is thus essentially determined by the flow resistance of the pressure control valve 31 and the tank jet pumps 13. Because of the flow resistance of the tank jet pumps 13, which is dependent on the ambient pressure, there is therefore a slight proportional characteristic of the pressure in section 27a of the return line.
- inlet 4 1 and outlet 47 are arranged opposite one another.
- the slide 33 has an annular groove 48, which in the rest position, as shown in FIG. 3, more or less opens inlet 41 and outlet 47.
- the pressure of the section 27a of the return line is led via a separate control line 49 into the space delimited by the second end face 43 of the slide 33.
- Inlet 41 and outlet 47 can also be arranged slightly offset from one another, so that, for example, first the inlet is released from the annular groove 48 and then the outlet 47 is released.
- the operating behavior of the pressure control valve 31 can be influenced by this measure.
- a pressure control valve 31 designed as a diaphragm valve is shown in FIG.
- a membrane 51 divides the space enclosed by a housing 53 into two subspaces.
- a first side 55 of the membrane 51 is acted upon via the control pressure connection 39 by the pressure in the supply line 21 or the delivery pressure of the prefeed pump 1 (both not shown).
- a control spring 45 and the pressure of the fuel which flows in the inlet 41 act on a second side 57 of the membrane.
- a valve body 59 designed as a ball which is held in an insert 61 of the membrane 51, is pressed against a valve seat 63, which closes the outlet 47.
- the outlet 47 is released and the pressure in the inlet 41 decreases.
- the inlet 41 is connected to the first section 27a of the return line.
