  Embodiments to which the present invention is applied will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a common rail fuel injection system for a diesel engine that employs a cementer 10 according to an embodiment to which the present invention is applied. FIG. 2 is a longitudinal sectional view showing a schematic configuration of the cementer 10.

  As shown in FIG. 1, the common rail fuel injection system of the present embodiment includes a fuel tank 1, a cementer 10 attached to the fuel tank 1, a fuel filter 2, a supply pump 3, a common rail 4, and an injector 5. And.

  Although the supply pump 3 is not shown in a specific configuration, for example, a feed pump (low pressure feed pump) that can use a trochoid pump or a vane pump, a solenoid valve as a flow control device, and For example, it is comprised from the high pressure pump etc. which consist of plunger type pumps. When the supply pump 3 is operated, the normal pressure fuel stored in the fuel tank 1 is sucked, flows through the fuel pipe 6 and is supplied into the common rail 4. At that time, water is separated from the fuel in the cementer 10, and foreign matters in the fuel are captured in the fuel filter 2.

  The common rail 4 holds the fuel pressurized by the high-pressure pump of the supply pump 3 in an accumulated state. An injector 5 that injects fuel into each cylinder of the engine is connected to the common rail 4 according to the number of cylinders, and the fuel held in the pressure accumulation state inside the common rail 4 is injected from the injector 5. A return pipe 7 is connected to the common rail 4, and surplus fuel in the common rail 4 is returned to the fuel tank 1 via the return pipe 7.

  Low-pressure fuel that flows into the control pressure chamber of each injector 5 and is discharged from the injector 5 low-pressure port such as fuel and leak fuel used for injector operation, and low-pressure fuel such as leak fuel from the supply pump 3 also recirculate. It joins the pipe 7 and returns to the fuel tank 1.

  Further, the common rail fuel injection system of the present embodiment is connected to an ECU (not shown) as a control means. This ECU optimally controls the flow rate of the fuel discharged from the supply pump 3 based on the input fuel pressure inside the common rail 4, the engine speed Ne, the accelerator opening α, and the like. Further, the ECU controls the opening / closing timing of the solenoid valve of the injector 5 connected to the common rail 4. Thus, the fuel injection timing and the fuel injection amount into each cylinder of the engine are controlled.

  As shown in FIG. 2, the cementer 10 includes a suction pipe 20 (corresponding to a suction pipe), a water separation member 30 (corresponding to water separation means), a water reservoir 40 (corresponding to a water reservoir body), and a cap 50 (cap). (Corresponding to the member), the reservoir 100 and the like.

  The reservoir 100 is, for example, a bottomed cylindrical (bottomed cylindrical in this example) resin container body, which is placed on the bottom surface 1c in the fuel tank 1 and contains fuel in the fuel tank 1 therein. To hold a part of. The reservoir 100 is provided with a through-passage provided with, for example, a jet pump (not shown) or a check valve so that the fuel level in the reservoir 100 is equal to or higher than the fuel level in the fuel tank 1. It has become. As a result, even if the vehicle equipped with the fuel injection system of the present embodiment is tilted (that is, even if the fuel tank 1 is tilted), part of the fuel in the fuel tank 1 is always and reliably stored in the reservoir 100. It can be put on hold.

  A suction pipe 20 extending in the vertical direction is disposed at a substantially central portion of the cylindrical portion of the reservoir 100. The suction pipe 20 has a lower end portion in the vicinity of the bottom surface of the reservoir 100 (that is, in the vicinity of the bottom surface 1c of the fuel tank 1), and a suction filter 21 made of unemployed cloth is provided at the lower end portion.

  The suction pipe 20 extends so as to penetrate the bottom surface of the water reservoir 40, and the upper end portion is in the vicinity of the cap 50. At the upper end portion of the suction pipe 20, a flange portion 22 that extends in the radially outward direction is formed. A water separating member 30 for separating moisture from the fuel that has passed through the suction pipe 20 is disposed above the flange portion 22. The water separation member 30 is made of, for example, a non-woven cloth having water repellency, and agglomerates water in the fuel passing through the inside to enlarge water droplets, thereby separating water from the fuel.

  The water reservoir 40 is, for example, a bottomed cylindrical (bottom cylindrical in this example) resin container body, and a cap 50 is disposed so as to cover the upper end of the opening (the upper end in the figure). The container 40 and the cap 50 are integrated by being fixed to each other, for example, by welding or adhesion. A space inside the water reservoir 40, that is, a space surrounded by the water reservoir 40 and the cap 50 is a space for storing water separated from the fuel by the water separation member 30. Since water has a higher specific gravity than fuel (light oil in this example), in the water reservoir 40, the water is stored on the bottom side of the lower part, and the fuel from which the water has been removed is stored above the water.

  The cap 50 is a substantially flat resin member, for example. The cap 50 is attached to the ceiling surface 1 a of the fuel tank 1 from the outside of the fuel tank 1, and the opening 1 b formed on the ceiling surface 1 a of the fuel tank 1. It is a member for closing.

  The cap 50 has a shape corresponding to the shape of the opening 1b, a fitting portion 51 that fits inside the opening 1b, and a flange portion 52 that is formed on the upper end of the fitting portion 51 over the entire circumference. It is made up of. The flange part 52 is a part which overlaps with the peripheral part of the opening part 1b of the fuel tank 1 ceiling surface 1a. The cap 50 closes the opening 1b by fixing the flange 52 to the ceiling surface 1a of the fuel tank 1 by, for example, screwing.

  On the lower surface side of the fitting portion 51 of the cap 50, an annular wall 53 protruding downward in a ring shape (circumferentially in this example) is integrally formed. The water separation member 30 is sandwiched between the flange portion 22 of the suction pipe 20 and the fitting portion 51 of the cap 50 inside the annular wall 53. The outer diameter of the flange portion 22 of the suction pipe 20 is smaller than the inner diameter of the annular wall 53, and the water separated by the water separation member 30 is between the flange portion 22 of the suction pipe 20 and the annular wall 53. The water drops in the water reservoir 40 and falls into the water reservoir 40.

  The cap 50 is integrally formed with a drain pipe 60 (corresponding to a drain pipe) and a fuel pipe 70 (corresponding to a fuel outlet pipe) both extending in the vertical direction and penetrating the fitting portion 51. That is, the drain pipe 60 and the fuel pipe 70 both extend upward from the inside of the water reservoir 40 and penetrate the cap 50.

  The lower end 61 (lower opening end) of the drain pipe 60 is located near the bottom surface of the water reservoir 40 so that water accumulated in the water reservoir 40 can be discharged through the drain pipe 60. It has become. On the other hand, the lower end 71 (lower opening end) of the fuel pipe 70 is located in the upper part of the water reservoir 40 (near the cap 50 above the lower end 61 of the drain pipe 60). Fuel accumulated in the upper part of the water can be led out to the outside.

  Since the water reservoir 40 and the cap 50 are fixed and integrated with each other, the lower ends of the drain pipe 60 and the fuel pipe 70 integrally formed with the cap 50 are arranged at predetermined positions in the water reservoir 40. The Specifically, due to the mutual fixation of the water reservoir 40 and the cap 50, the height (axial dimension) of the lower end 61 of the drain pipe 60 and the lower end 71 of the fuel pipe 70 from the bottom surface of the respective water reservoir 40. It is determined.

  That is, when the cap 50 integrally formed with the drainage pipe 60 is fixed to the water reservoir 40, the drainage pipe 60 and the water reservoir 40 are integrated, and the position of the lower end 61 of the water drainage pipe 60 relative to the water reservoir 40 in the axial direction. Has been determined. Further, the cap 50 integrally formed with the fuel pipe 70 is fixed to the water reservoir 40, whereby the fuel pipe 70 and the water reservoir 40 are integrated, and the position of the lower end 71 of the fuel pipe 70 with respect to the water reservoir 40 is determined in the axial direction. ing.

  As shown in FIG. 1, in the middle of the flow path of the drain pipe 60, a drain pump 80 (pump means) that drains water accumulated in the water reservoir 40 to the outside of the fuel tank 1 through the drain pipe 60. Is equivalent). On the other hand, the upstream end of the fuel pipe 6 is connected to the upper end (downstream end) of the fuel pipe 70.

  Further, as shown in FIG. 2, the water level inside the water reservoir 40 is higher than the lower end 61 of the drain pipe 60 by a predetermined level (the predetermined water level with reference to the lower end 61 of the drain pipe 60). ) Is provided. A water level sensor 90 (corresponding to a water level detecting means) is provided for detecting whether or not the pressure has reached. The water level sensor 90 detects whether or not the water level inside the water reservoir 40 has reached a predetermined level (predetermined water level with reference to the bottom surface of the water reservoir 40) above the lower end 61 of the drain pipe 60. It can also be said that it is a means.

  The water level sensor 90 only needs to be able to detect whether or not water has accumulated in the water reservoir 40 to a level that needs to be discharged. The water level sensor 90 detects a predetermined water level based on the lower end 71 of the fuel pipe 70. May be. The water level sensor 90 may be a float type sensor or an electric type sensor.

  Further, the drain pump 80 described above may be a manual pump or an electric pump. When the water level sensor 90 detects that water has accumulated in the water reservoir 40 to a level that needs to be discharged, the water level sensor 90 notifies the user, service person, etc., using a means for notifying the user and the service person, etc. By operating the pump 80, the water accumulated in the water reservoir 40 can be discharged to the outside of the fuel tank 1 through the drain pipe 60. In the case where the drainage pump 80 is electrically operated, when the water level sensor 90 detects that water has accumulated in the water reservoir 40 to a level that requires drainage, the drainage pump 80 is operated to automatically drain water. It may be a thing.

  Although not shown in FIG. 2, as shown in FIG. 1, a pipe to which the downstream end of the reflux pipe 7 is connected is integrally formed on the cap 50, and the inside of the fuel tank 1 is connected via the reflux pipe 7. The fuel recirculated to the inside flows into the reservoir 100.

  As shown in FIG. 2, the reservoir 100 is locked to the cap 50 via a support column 54. The upper end portion of the support column 54 is fixed to the cap 50, and the lower end portion of the support column 54 is fitted in a hole formed in the support portion 101 of the reservoir 100 so as to be movable in the axial direction (vertical direction in the drawing). The reservoir 100 is always urged downward by a compressed spring 55 disposed around the support column 54 coaxially with the support column 54. The reservoir 100 is pressed against the bottom surface 1 c of the fuel tank 1 by the biasing force of the spring 55. Although only a part is shown in FIG. 2, a plurality of (two in this example) configurations including the support pillars 54 and the springs 55 are provided.

  As is clear from FIG. 2, the suction pipe 20, the suction filter 21, the water separation member 30, the water reservoir 40, the support column 54, the spring 55, and the reservoir 100 are all axes of the fitting portion 51 of the cap 50. It is disposed within the direction (vertical direction in the figure) projection range. That is, when viewed from the vertical direction, each of the above-described configurations is located inside the outer periphery of the fitting portion 51 of the cap 50. Therefore, when the cementer 10 is mounted on the fuel tank 1 from above, all the components positioned below the cap 50 can be inserted through the opening 1b of the fuel tank 1 ceiling surface 1a.

  Next, the operation of the cementer 10 will be briefly described based on the above configuration.

  When the supply pump 3 is operated, the fuel pipe 6 on the upstream side of the supply pump 3 has a negative pressure due to the action of the feed pump, and normal pressure fuel stored in the fuel tank 1 is sucked. After the foreign matter is removed by the suction filter 21, the fuel held in the reservoir 100 of the cementer 10 is sucked upward through the suction pipe 20. The water that has flowed out from the upper end of the suction pipe 20 is separated by the water separation member 30. The water separated from the fuel is accumulated on the bottom surface side of the water reservoir 40, and the fuel from which the water has been separated and removed is accumulated in the water reservoir 40 above the water accumulated on the bottom surface side.

  The fuel in the water reservoir 40 flows into the fuel pipe 70 from the lower end 71 of the fuel pipe 70, is led out of the fuel tank 1 through the fuel pipe 70, and travels toward the fuel filter 2. On the other hand, when the water level sensor 90 detects that the water level has risen to the predetermined water level, the water collected on the bottom side in the water reservoir 40 is drained from the lower end 61 of the drain pipe 60 by the operation of the drain pump 80. It flows into the pipe 60 and is discharged outside the fuel tank 1 through the drain pipe 60.

  According to the above-described configuration and operation, when the cementer 10 is attached to the ceiling surface 1 a of the fuel tank 1, the water separated by the water separating member 30 from the fuel sucked from the reservoir 100 through the suction pipe 20. The water reservoir container 40 that stores water is disposed on the ceiling surface 1 a side in the fuel tank 1. As shown in FIGS. 1 and 2, since the fuel tank 1 is not generally used to fill up to the ceiling surface 1a, the water reservoir 40 is placed on the side of the ceiling surface 1a in the fuel tank 1 as in this embodiment. It is difficult to sacrifice the fuel storage capacity of the fuel tank 1. Moreover, if the cementer 10 of this embodiment is used, since the fuel filter 2 does not require a water separation function, the fuel filter 2 can be reduced in size. Therefore, a sufficient space for mounting various devices in the vehicle can be secured, and the fuel storage capacity of the fuel tank 1 can be easily secured.

  Further, the water separation member 30 is disposed inside the water reservoir 40. Therefore, the water separated from the fuel by the water separation member 30 can be stored inside the water reservoir 40 without easily escaping.

  Further, the drain pipe 60 and the fuel pipe 70 are both provided so as to penetrate the cap 50. Therefore, it is not necessary to form holes for penetrating the pipes 60 and 70 other than the opening 1b in the fuel tank 1.

  Further, both the drain pipe 60 and the fuel pipe 70 are integrally formed with the cap 50. Therefore, the manufacture of the cementer 10 and the attaching / detaching operation of the cementer 10 to / from the fuel tank 1 are easier than in the case of separate bodies.

  Further, the height of the lower end 61 of the drain pipe 60 and the lower end 71 of the fuel pipe 70 from the bottom surface of each of the water reservoirs 40 is determined by the mutual fixation of the water reservoir 40 and the cap 50. Accordingly, water can be reliably discharged from the inside of the water reservoir 40 through the drain pipe 60 and fuel can be reliably led out from the inside of the water reservoir 40 through the fuel pipe 70.

  Further, the cementer 10 of this embodiment includes a drain pump 80 in the drain pipe 60. Therefore, water can be discharged from the water reservoir 40 very easily. Further, a water level sensor 90 for detecting the water level inside the water reservoir 40 is provided, and when the water level sensor 90 detects that water has accumulated in the water reservoir 40 to a level that needs to be discharged, the drain pump 80 is turned on. It is possible to notify the user to activate the drainage, or to operate the drainage pump 80 to perform the automatic drainage.

  Further, the cementer 10 includes a reservoir 100 that is placed on the bottom surface 1 c in the fuel tank 1 and secures a fuel level equal to or higher than the fuel level in the fuel tank 1. Therefore, the fuel can be reliably sucked up from the lower part in the fuel tank 1 through the suction pipe 20 and supplied to the water separation member 30.

  In addition, the constituent elements such as the reservoir 100 arranged below the cap 50 in the cementer 10 are all directly or indirectly locked to the cap 50 and integrated with the cap 50. ing. In addition, all the components disposed below the cap 50 are disposed within the projection range of the fitting portion 51 of the cap 50 in the axial direction (the vertical direction in the drawing). Therefore, when the cap 50 is attached to the fuel tank 1 ceiling surface 1a so as to close the opening 1b, all the components such as the water reservoir 40 and the reservoir 100 provided below the cap 50 are simultaneously installed. The fuel tank 1 can be disposed at each predetermined position. Also, it is very easy to attach and detach the fuel tank 1 when replacing the cementer 10.
