Abstract
A apparatus separates out and removes water present in liquid fuels. The fuel supplies an internal combustion engine by a fuel delivery pump (12). Water is separated out at a filter (5) having a collecting space (27) for collecting separated water and connected upstream of the suction side (11) of the fuel delivery pump (12). The pump suction action counteracts outflow of water from the collecting space (27). Depending on the amount of water collected, the pump suction action is negated, and an outlet valve at an outflow orifice (37) of the collecting space (27) is opened by a discharge (43, 53) producing a pressure gradient enabling the discharge of water from the collecting space (27) over a discharge period when the fuel delivery pump (12) is operating.
Description
- This application is a division of U.S. patent application Ser. No. 12/225,917, the entire subject matter of which is incorporated herein by reference.
- The invention relates to a process for separating out and removing water present in liquid fuels, especially water from diesel oil. The fuel is conveyed in a line system to supply an internal combustion engine by a fuel delivery pump. Water is separated out at a filter arrangement having a collecting space for collecting the separated water and is connected upstream from the suction side of the fuel delivery pump so that its sucking action counteracts an outflow of water from the collecting space. Depending on the collection of a given amount of water at the filter arrangement, the sucking or suction action of the delivery pump is negated, and an outlet valve located at an outflow orifice of the collecting space for removing water is opened. Moreover, the invention relates to an apparatus for executing this process.
- The drainage of water, with these measures being carried out, is conventional and is especially essential when heavy diesel machinery is operated under severe use conditions. For example, when using heavy machinery with heavy diesel engines in less highly developed countries, obtaining fuel of Central European quality is difficult. In fact, in countries with difficult climatic conditions and poor infrastructure, users must expect that the available fuel will have significant impurities, in particular a high water content. Construction and agricultural machinery is often fueled from barrels stored and transported more often with little or no covering at all, so that they are exposed unprotected to the elements such as rain.
- According to experience, a maximum water content in diesel oil of up to 10% can be expected. Vandalism and corrupt handling can be responsible for these high water contents.
- When highly contaminated diesel oil is used, for example, in the tank of a high-performance common rail diesel engine with consumption of approximately 400 l/day, the amount of water to be drained is about 40 l/day. For commercial filters/water separators the capacity in the water collecting tank is at most 0.5 l. In view of this prior art, the operator, to carry out the conventional drainage process, must shut off the engine roughly 80 times during the workday to negate the suction force of the fuel delivery pump counteracting the outflow of water from the filter arrangement. The operator must also open the outflow orifice of the water collecting space to allow the collected water to flow out. If the operator does not observe the requirements, after some time water bleeds through the filter arrangement into the injection system damage it, resulting in very high maintenance costs and a correspondingly long downtime of the pertinent device.
- An object of the invention is to provide a process meeting the requirements arising in operation of internal combustion engines, in particular heavy diesel engines, to an especially satisfactory degree.
- Proceeding from conventional processes, this object is basically achieved according to the invention by negating the sucking action counteracting the outflow of water by a discharge. The discharge produces a pressure gradient enabling outflow of water at the outflow orifice of the collecting space over a discharge interval and during current operation of the fuel delivery pump.
- The discharge process is initiated by a pressure difference produced between the inside of the collecting space and the outside causing discharge of water via the outflow orifice. The process according to the invention then enables discharge processes to be carried out while the engine is running Therefore, discharge processes can be carried out in comparatively rapid succession and over comparatively short discharge intervals, without disrupting operation and during operation of the injection system, with the fuel delivery pump continuing to run. The storage volume of the injection system can be discharged without needing to shut down the engine.
- The process according to the invention enables the option of complete automation. In an especially advantageous manner, a water sensor unit detecting collection of a given amount of water and its outflow produces a signal to activate the discharge means and to automatically initiate a discharge process. The danger that the water can bleed through due to operator error is therefore prevented.
- In especially advantageous embodiments, the discharge has control electronics processing the signal of the water sensor unit to determine the discharge intervals and to produce control signals for activation of the discharge and control of the outlet valve during the determined discharge intervals.
- The pressure gradient enabling outflow of water at the outflow orifice can be produced in different ways. For example, the discharge can have a discharge pump with a suction side connected to the outflow orifice of the collecting space and producing a pressure gradient when the discharge is activated. This embodiment constitutes a comparatively simple procedure in which sucking of water out of the collecting space takes place as necessary while the system remains in operation, without the need for interventions or changes on the actual line system.
- Alternatively, the discharge has a hydropneumatic accumulator with an oil side charged with fuel by the fuel delivery pump, and a valve actuatable by the control electronics. By the accumulator in the filter arrangement over a discharge interval, a pressure is built up producing the pressure gradient necessary for outflow of water at the outflow orifice. In this form of the process, the advantage is that an additional discharge pump is not necessary.
- Advantageously, depending on the signal of a temperature sensor detecting the temperature of the separated water, the control electronics can produce a heating control signal for a heating element. The heating element is designed to protect against freezing. In this way operating reliability is ensured even in winter operation or in cold climate zones.
- The subject matter of the invention is also an apparatus for carrying out the process according to the invention.
- Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
- Referring to the drawings which form a part of this disclosure:
-
FIG. 1 shows a simplified operating or schematic diagram of a system according to a first exemplary embodiment of the invention; -
FIG. 2 is a simplified operation or schematic diagram of a system according to a second exemplary embodiment of the invention; -
FIG. 3 is a schematic side elevational view partially in section of an apparatus according to the system ofFIG. 1 ; and -
FIG. 4 is a schematic front elevational view partially in section of the apparatus ofFIG. 3 , turned 90 relative toFIG. 3 . - To illustrate a first exemplary embodiment of the invention,
FIG. 1 shows a schematic block diagram of the fuel supply system of a diesel engine with common rail injection. Emerging from a fuel tank 1 the line system has atank line 3 leading to theinlet 6 of aprefilter 5. Theprefilter 5 with a fineness of approximately 30 μ has awater separator 7. Theoutlet 8 of theprefilter 5 is connected to asuction line 9 leading to thesuction side 11 of afuel delivery pump 12. Itspressure line 13 is connected to theinlet 15 of afine filter 17 having a fineness of approximately 2-5 μ. Theoutlet 19 of thefine filter 17 is connected to a commonrail injection system 21 with itsinjection nozzles 23.Nozzles 23 are connected by arecirculation line 25 leading back to the tank 1. - Water separated from the fuel flowing through the
prefilter 5 by thewater separator 7 collects in the bottom region of theprefilter 5 and in thecollecting space 27 adjoining the underside ofprefilter 5. Details of the fluid connection and the positional relationship between thewater separator 7 and thecollecting space 27 are explained below usingFIGS. 3 and 4 . Awater sensor unit 29 detects the height of the level of the collected water in thecollecting space 27 and is connected by and transmits signals to thecontrol electronics 31. Thecontrol electronics 31 processes not only the signals of thewater sensor unit 29, but also those of atemperature sensor 33 to activate aheating element 35 in thecollecting space 27 when a freezing temperature has been ascertained. - The
collecting space 27 is connected via itsoutflow orifice 37 to thesuction side 41 of thedischarge pump 43. The discharge pump pressure side leads to acapture tank 45 for the discharged water. Thepump 43 can be a pump version which blocks against backflow. Alternatively, anonreturn valve 39 can be the outlet valve between theoutflow orifice 37 and thepump 43. - When the
water sensor unit 29 detects a level in the collectingtank 27 corresponding to a given amount of collected water and signals this condition to thecontrol electronics 31, a discharge process is initiated by thecontrol electronics 31 starting the motor of thepump 43 via thesupply line 47. The intake capacity of thepump 43 is chosen such that its sucking or suction action exceeds the sucking or suction action of thefuel delivery pump 12 so that at theoutflow orifice 37 of the collecting space a pressure gradient is produced such that the collected water flows out, i.e., is sucked out by thepump 43. The duration of the discharge interval with thepump 43 remaining on can be determined depending on the signal of thesensor unit 29. Operation of thepump 43 is adjusted by a certain amount when the water level drops, or can be controlled depending on time, by thepump 43 operating over a fixed time interval for each discharge process. In each instance thefuel delivery pump 12 remains in operation during the discharge processes so that the engine need not be shut down. - The example shown in
FIG. 2 differs from the example shown inFIG. 1 by the use of a discharge in the form of a pressure control which replaces thedischarge pump 43 fromFIG. 1 . Components which correspond to the example fromFIG. 1 are designated inFIG. 2 with the same reference numbers as inFIG. 1 . As is apparent fromFIG. 2 , thepressure line 13 of thefuel delivery pump 12 leads not only to theinlet 15 of thefine filter 17, but also to theoil side 51 of adiaphragm accumulator 53 charged with fuel by the operatingfuel delivery pump 12. To initiate a discharge process taking place as in the first embodiment by delivering the signal from thesensor unit 29 and by the resulting activity of thecontrol electronics 31, a 3/2-way valve 55 connected upstream from theinlet 6 of theprefilter 5 in thetank line 3 and a 2/2-way valve 57 connected downstream from theoutlet 8 of theprefilter 5 are actuated. During the discharge interval, the valve 57 is closed and the valve 55 is actuated such that thetank line 3 is blocked and theoil space 51 of thediaphragm accumulator 53 is connected to theinlet 6 of theprefilter 5 by abranch line 59 and the 3/2-way valve 55. At theoutflow orifice 37 of the collectingspace 27 the pressure gradient presses the collected water out of the collectingspace 27 to travel to thecapture tank 45. The pressure gradient is formed by the pressurized volume of oil supplied to theprefilter 5 by thediaphragm accumulator 53. In the example shown inFIG. 2 , theoutlet 8 of theprefilter 5 during the discharge interval can be blocked by the valve 57. When thediaphragm accumulator 53 is charged with enough pressure and a sufficiently large volume of pressurized oil flowing via the valve 55 into theprefilter 5 is available in theoil space 51 so that a sufficient pressure rise is formed in theprefilter 5 during the discharge interval, the 2/2-way valve can be omitted. As in the first described embodiment, during the discharge interval thefuel delivery pump 12 can continue to operate, i.e., the engine need not be shut down. When the discharge interval is ended, the valve 55, optionally the valve 57, is controlled again such that flow takes place through thetank line 3 and thesuction line 9. Thebranch line 59 is blocked again, and thediaphragm accumulator 53 is again charged by thepressure line 13. -
FIGS. 3 and 4 show one example of the apparatus according to the invention for executing the process. The apparatus is made as a retrofit system attachable to theunderside 61 of theprefilter 5 at a later time. Its filter casing is made in the form of a spin-on filter. - As
FIGS. 3 and 4 show, the central region of the bottom on theunderside 61 has awater outlet 63 with an internal thread. Ahollow screw 65 is screwed into that internal thread. Internal holes 67 ofscrew 65 form a fluid connection between the bottom region on theunderside 61 of the filter casing and acentral depression 69 located on the upper end of abody 71.Body 71 is tightened by thehollow screw 65 on theunderside 61 of the filter casing. Agasket 73 forms an edge-side seal. - The
depression 69 forms thewater collecting space 27 for the water separated out by thewater separator 7 of theprefilter 5. The water level in the collectingspace 27 is detected by thewater sensor unit 29. Underneath thedepression 69 forming the collectingspace 27, cavities are in thebody 71 for holding the control electronics 31 (seeFIG. 3 ), the discharge pump 43 (seeFIG. 4 ) and other components which are not shown. - While
FIGS. 3 and 4 show the apparatus according to the invention in an exemplary embodiment made as a retrofit system suited for installation into existing systems at a later time. The invention is also especially suitable as original equipment for the pertinent systems. - In particular, the apparatus according to the invention together with the
prefilter 5 having aseparator 7 and other system components, such as thepump 43,sensor unit 29,electronics 31, heating element and the like, can be combined in a standard housing. - While various embodiments have been chosen to illustrate the invention, it will be understood by those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention as defined in the appended claims.
