Further, the left-right direction in FIG. 1 is defined as the width direction, and the direction perpendicular to the paper surface is defined as the depth direction.

  First, the overall configuration of a stationary engine power generator 1 (hereinafter simply referred to as “engine power generator 1”) of the present invention will be described with reference to FIGS. The engine power generation device 1 is configured in a package type in which various devices are housed in a rectangular parallelepiped package 2 together with a base 3. The inside of the package 2 is divided into two upper and lower chambers by a partition wall 4 provided in the horizontal direction, and the lower side is an engine room 5. On the other hand, the upper side is divided into two chambers by a partition wall 6, the left side is an exhaust silencer chamber 7, and the right side is a ventilation chamber 8.

  In the engine room 5, a 6-cylinder water-cooled engine 9 (hereinafter referred to as “engine 9”) and a generator 10 that is coupled to a crankshaft C (only the center line is shown) of the engine 9 and is driven to rotate. And are installed. The engine 9 and the generator 10 are supported in a vibration-proof manner on a common platform 11 placed on the base 3 via a vibration-proof rubber or the like. One end of an exhaust pipe 20 penetrating the partition wall 4 in the vertical direction is connected to the exhaust port of the engine 9. The other end of the exhaust pipe 20 is connected to an exhaust silencer 30 housed in the exhaust silencer chamber 7. It is connected.

  Similarly, in the engine room 5, a control unit 14 configured by a generator panel 12 and an auxiliary machine panel 13 to control the operation of the engine power generator 1, a fuel tank 15 of the engine 9, a lubricating oil system and cooling of the engine 9. Various devices constituting the water system are arranged and accommodated in the package 2. In addition, an air inlet is formed in a part of the partition wall 4 that partitions the engine room 5 and the ventilation chamber 8, and ventilation fans 81 and 81 are fixed so as to cover the air inlet. When the ventilation fans 81 and 81 are driven, air (outside air) is taken into the ventilation chamber 8 via the intake duct 2a attached to the intake ports formed on the front side and the back side of the package 2, and the engine room 5 is led. A soundproof split 82 is mounted on the partition wall 4 and stored in the ventilation chamber 8.

  In the engine power generator 1 of the present invention, the engine 9 is of an air start type. For the air start engine 9, an air start system including an air compressor 16, an air dryer 17, and an air tank 18 is provided. In this air starting system, the compressed air compressed by the air compressor 16 is dehumidified by the air dryer 17 and sent into the air tank 18 for filling. The compressed air in the air tank 18 drives an air motor (air starter) of the engine 9. In this configuration, an air starting system including an air compressor 16, an air dryer 17, and an air tank 18 is housed in the package 2.

  Thus, by storing the air start system of the engine 9 in the package 2, the air start system is separated into a separate unit and installed outside the package 2. A single unit can be realized even when the engine is used. Thereby, simplification of the local construction in the installation site of the engine power generator 1 and space saving can be achieved.

  As described above, the engine 9, the generator 10, the control unit 14, the fuel tank 15, and various devices constituting the lubricating oil system and the cooling water system of the engine 9 are arranged and stored in the package 2. However, in the engine power generation device 1 of the present invention, the cooling device including the radiator 55 for cooling the engine 9 and the radiator fan 56 is formed as a separate unit outside the package 2. ing. That is, the radiator 55, the radiator fan 56, and the like are housed in a rectangular parallelepiped package 52 together with the base 53 outside the package 2, so that the cooling device constituted by these is configured in a package type and separated into separate units. Has been. Specifically, the package 2 and the package 52 can be separated in the width direction at the position of the arrow X in FIG.

  The radiator 55 is disposed along the front and back side surfaces in the package 52, and is a cooling water circuit extending from the package 2 between the front-side radiator 55 and the back-side radiator 55. And a cooling water circuit 57 that communicates with each radiator 55. A radiator fan 56 is disposed above these radiators 55.

  In addition, the package 52 constituting the cooling device has a depth direction dimension substantially the same as the depth dimension of the package 2, and the package 52 is adjacent to the package 2 as shown in FIGS. 1 to 3. When arranged, the package 2 and the package 52 form a rectangular parallelepiped shape that is integrated in appearance. In other words, the package 52 constituting the cooling device does not need to be arranged integrally with the package 2, and can be installed separately from the package 2.

  In this way, the cooling device for cooling the engine 9 is formed as a separate unit outside the package 2, whereby the radiator 55 and the radiator fan 56 constituting the cooling device are housed in one package 2. The expansion of the dimension in the width direction (longitudinal direction) of (and the base 3) can be avoided. As a result, the degree of freedom at the time of installing the engine power generation device 1 is improved, the minimum space required for installing the engine power generation device 1 is reduced, and it is possible to flexibly deal with securing the space, and the engine power generation The transportability of the apparatus 1 can be improved.

  As a specific installation mode of the engine power generator 1 having such a configuration, for example, the cases shown in FIGS. 4 and 5 are conceivable. In the following description, a unit configuration housed in the package 2 is referred to as a power unit P, “package 2” is referred to as “power unit package 2”, and a cooling device having a unit configuration housed in the package 52 is referred to as a radiator unit R. The “package 52” is referred to as a “radiator unit package 52”.

  FIGS. 4 and 5 each show a case where two sets of engine power generators 1 are installed. First, in FIG. 4, two sets of engine power generators in a state where the power unit P and the radiator unit R are arranged adjacent to each other are shown. 1 shows the case where it arrange | positions in parallel with the width direction. In this case, as shown in FIGS. 1 to 3, the power unit P and the radiator unit R form a rectangular parallelepiped shape that is integrated in appearance. Such an installation pattern is suitable for an installation space partitioned into a rectangular shape.

  FIG. 5 shows a case where the power unit P and the radiator unit R are installed separately. In this case, the radiator unit R is arranged with respect to the power unit P in the width direction. Such an installation pattern is suitable in the case of an installation space that is partitioned in a square shape and has a margin in the width direction and the depth direction with respect to the engine power generator 1. 4 and 5, reference numeral 24 denotes an exhaust gas boiler. Exhaust gas discharged from the engine 9 guided through the exhaust pipe 23 is recovered as heat by the exhaust gas boiler 24 as steam and used for heating or the like. Used. Reference numeral 25 denotes a connection panel for connecting and controlling two sets of engine power generators 1.

  Thus, the arrangement configuration of each device in the engine power generator 1 configured by the power unit P and the radiator unit R that can be installed separately will be described below.

  In the power unit package 2, for example, a sound absorption expansion attenuation type exhaust silencer 30 is accommodated in the exhaust silencer chamber 7 which is the space above the engine 9. The exhaust silencer 30 has a two-stage configuration having two cylindrical silencing chambers (primary silencing chamber 31a and secondary silencing chamber 31b) having a circular cross-sectional shape. The longitudinal direction is arranged so as to be parallel to the axial direction of the crankshaft C of the engine 9. And among each silencing chamber 31a * 31b, the primary silencing chamber 31a is arrange | positioned at the non-control side, and the secondary silencing chamber 31b is arrange | positioned at the control side (refer FIG. 3).

  The exhaust pipe 20 extending from the engine 9 is connected to an exhaust inlet formed on one end side of the primary silencing chamber 31a arranged on the non-pilot side, and the other end side of the primary silencing chamber 31a is connected to the other end side of the primary silencing chamber 31a. A communication pipe 32 is connected, and the primary muffler chamber 31a communicates with the secondary muffler chamber 31b disposed on the control side via the communication pipe 32. An exhaust pipe 33 constituting an exhaust outlet of the exhaust silencer 30 is connected to the secondary silencer chamber 31b. For example, as described above, the exhaust gas boiler 24 shown in FIGS. 4 and 5 is connected to the exhaust pipe 33. An exhaust pipe 23 communicating with the like is connected. Exhaust gas generated by driving the engine 9 is guided into the exhaust silencer 30 through the exhaust pipe 20, is silenced through the primary silencer chamber 31 a and the secondary silencer chamber 31 b, and is exhausted through the exhaust pipe 33. It is discharged outside the power generator 1.

  As described above, the exhaust muffler 30 having the two-stage configuration including the primary muffler chamber 31a and the secondary muffler chamber 31b attenuates the exhaust sound of the engine 9 in two stages. Therefore, the exhaust noise of the engine 9 leaking outside the power unit package 2 can be reduced. Furthermore, it is possible to set a predetermined attenuation amount in each of the muffler chambers 31a and 31b.

  Further, by arranging one of the two muffler chambers 31a and 31b constituting the exhaust muffler 30 housed in the exhaust muffler chamber 7 to the control side and the other to the non-control side, the power unit package 2 The internal space can be used effectively, and the overall height of the power unit package 2 can be suppressed.

  By the way, in a stationary apparatus such as the engine power generator 1, on-site maintenance and maintenance of the engine 9 are periodically performed. At this time, the piston in the engine 9 is extracted, and the piston is cleaned or replaced. Along with this, the cylinder liner and piston ring are cleaned and replaced. Therefore, as described above, the muffler chambers 31a and 31b of the exhaust silencer 30 that are arranged separately on the control side and the non-control side are arranged substantially symmetrically with respect to the crankshaft C of the engine 9, and A chain block (winding machine) mounting bar 34 (hereinafter simply referred to as “mounting bar 34”) for extracting the piston of the engine 9 is disposed between 31a and 31b in parallel to the axial direction of the crankshaft C. (See FIG. 6).

  The engine 9 in the engine room 5 is arranged such that the position of the crankshaft C is substantially in the center with respect to the depth direction in the power unit package 2, and each of the sound deadening rooms 31a and 31b of the exhaust silencer 30 is Are arranged symmetrically with respect to the crankshaft C. And the space formed in the lower part of the cylindrical outer peripheral surface where the cross-sectional shape is circular between the muffler chambers 31a and 31b that are arranged close to each other in parallel in the exhaust muffler chamber 7 In addition, a mounting bar 34 is installed. The lower space between the two silencing chambers 31a and 31b is formed above the crankshaft C because the silencing chambers 31a and 31b are arranged substantially symmetrically with respect to the crankshaft C. That is, the attachment bar 34 is for attaching a chain block (winding machine) 35 for extracting a piston housed in each cylinder of the engine 9 connected in the width direction in the engine power generator 1. As described above, it is necessary to be disposed substantially directly above the crankshaft C (see FIG. 7).

  FIG. 7 shows a specific aspect when the piston of the engine 9 is extracted. That is, the chain block 35 is attached to the attachment bar 34 by the upper hook 37 fixed to the main body 36 of the chain block 35 being locked to the attachment bar 34. One end of a load chain (not shown) is fixed to the main body 36, and a lower hook 38 to which a piston 39 is locked is attached to the other end of the load chain. Further, a locking tool 40 such as an eyebolt is attached to the upper surface of the piston head 39 a of the piston 39, and the lower hook 38 is locked to the locking tool 40. In this state, by operating a hand chain (not shown) that hangs down from the main body 36 (by operating a button in the case of an electric type), the load chain is wound up, and the piston 39 is moved upward from each cylinder of the engine 9 Pull out.

  In the past, for example, the silencer chamber of the exhaust silencer was configured with an ellipse or the like in cross-sectional shape, so a sufficient space could not be obtained below the exhaust silencer. The two silencer chambers 31a and 31b of the exhaust silencer 30 are formed in a cylindrical shape and a mounting bar 34 is provided between them, so that the exhaust silencer 30 is located above the crankshaft C of the engine 9 and below the exhaust silencer 30. Since a sufficient working space can be secured, the workability at the time of extracting the piston 39 of the engine 9 can be improved.

  Further, when performing the operation of extracting the piston 39 as described above, the engine chamber 5 and the exhaust silencer chamber 7 need to communicate with each other at least in the upper part of the crankshaft C of the engine 9. For this reason, as shown in FIG. 6, the partition wall 4 that partitions the engine room 5 and the exhaust silencer chamber 7 includes a top plate 44 that partitions the upper space of the engine 9 in a portion located above the engine 9. Is provided so as to be removable. Specifically, in the present embodiment, the top plate 44 is provided at a substantially central portion in the depth direction that is located above the engine 9 in the partition wall 4, and is divided into approximately three equal parts in the width direction. On the other hand, it is detachable. The top plate 44 provided on the partition wall 4 has a shape and an area that can secure a sufficient work space when the piston 39 of the engine 9 is pulled out with the top plate 44 removed. The shape and the dividing method are not limited to this embodiment.

  Thus, by providing the partition plate 4 so that the top plate 44 can be removed, it is not necessary to secure a space in the engine chamber 5 for extracting the piston 39 of the engine 9. Can be suppressed.

  Moreover, the top plate 44 provided so that removal is possible is comprised so that it can remove below. That is, the top plate 44 can be removed from the engine room 5 side. Specifically, a fixing portion for fixing the top plate 44 to the partition wall 4 is provided so that it can be operated from the engine room 5 side, and the top plate 44 is removed by dropping into the inside of the engine room 5. It is configured.

  In this way, the top plate 44 can be removed downward, so that when the piston 39 of the engine 9 is pulled out, the exhaust silencer in the exhaust silencer chamber 7 is used to remove the top plate 44. It is not necessary to remove 30 and workability can be improved.

  As for the on-site maintenance and maintenance of the engine 9, the main bearing metal (journal metal) that supports the crank journal of the crankshaft C or the crankshaft C as the above-described piston 39 extraction work or individual work. Maintenance such as inspection and replacement of the crank pin metal (con rod bearing) used for the bearing part of the connecting rod that connects the piston and the piston is performed periodically (hereinafter referred to as “metal bearing”. That said.) Therefore, a maintenance space for the metal bearing is secured on at least one side of the steering side or the non-steering side with respect to the engine 9 in the power unit package 2.

  On both side surfaces (steering side and non-steering side) of the cylinder block of the engine 9, openings for communicating the inside and outside of the cylinder block are provided for each cylinder, and inspection windows 9b for covering these openings are provided. Is attached to the cylinder block with a fastener such as a bolt. Then, when performing maintenance of the metal bearing, the inspection window 9b is removed and the work is performed from the side of the engine 9. Therefore, as a maintenance space for the metal bearing, a maintenance space S as a space where no equipment is arranged is secured on the steering side of the engine 9 in the power unit package 2 (see FIG. 10).

  Specifically, no equipment is provided on the front side of the inspection windows 9b of all the cylinders of the engine 9, work for attaching and detaching the inspection windows 9b, and metal in the cylinder block of the engine 9 Sufficient work space is ensured so that the work for inspecting and replacing the bearings can be performed smoothly. In the maintenance space of the metal bearing in the power unit package 2, for example, a work table 43 used when performing work is placed. The inspection window 9b is also provided on the non-steering side surface of the engine 9, and maintenance of the metal bearing can be performed from both sides of the engine 9, so that the non-steering side of the engine 9 in the power unit package 2 is provided. In this case, a maintenance space may be secured as a space where the above-described devices are not disposed.

  Thus, by securing a maintenance space for the metal bearing of the engine in the power unit package 2, when maintenance of the metal bearing is performed at the installation site, other equipment may become an obstacle or other equipment. The workability can be improved without the need to remove the battery.

  Further, in the engine power generation device 1, the air start system of the engine 9 housed in the power unit package 2, the lubricating oil system, and the cooling water system are distributed to the control side and the non-control side in the power unit package 2. It is arranged. In the present embodiment, the air start system is disposed on the control side, and the lubricating oil system and the cooling water system are disposed on the non-control side.

  Here, the lubricating oil system and the cooling water system in the engine power generator 1 will be described. First, the lubricating oil system will be described with reference to FIG.

The oil pan 9c is connected to an auxiliary tank (circulation tank) 50 for supplementing the amount of the lubricating oil. The lubricating oil in the auxiliary tank 50 is also circulated as the lubricating oil supplied to each part of the engine 9. Has been. That is, the lubricating oil in the oil pan 9 c is guided to the auxiliary tank 50 through the bypass filter 49 by the motor pump 48. Here, when the lubricating oil passes through the bypass filter 49, impurities in the lubricating oil from the oil pan 9c are removed, and deterioration of the lubricating oil is suppressed. Then, the lubricating oil in the auxiliary tank 50 is returned again into the oil pan 9c. Thus, the sum of the amount of lubricating oil in the oil pan 9 c and the amount of lubricating oil in the auxiliary tank 50 is the total amount of lubricating oil circulating in the engine 9. Further, this lubricating oil system is provided with a replenishing tank 51 for replenishing lubricating oil consumed by long-term use and the like. The replenishing tank 51 is connected to the oil pan 9c, and is configured to detect the level of the lubricating oil in the oil pan 9c by the automatic replenishing device 51a and automatically replenish the lubricating oil into the oil pan 9c. It has become. Further, in this lubricating oil system, the lubricating oil is forcibly circulated in order to prevent seizure of the sliding portion before the engine 9 is started or when the engine 9 is stopped for a long time. A priming pump (lubricating oil pump) 60 is provided to supply the components (see FIG. 2).

  Next, the cooling water system will be described with reference to FIG. In the cooling water system, the cooling water cooled by the radiator 55 to the water jacket 9 a of the engine 9, the air cooler (intercooler) 41, and the lubricating oil cooler 42 is formed by a series of main pipes 65 a and 65 b constituting the cooling water circuit 57.

It is arranged with emphasis. In particular, in this embodiment, the power unit P is disposed on the side where the radiator unit R is provided, that is, on the left side in the power unit package 2.

  In this way, by arranging each system in the engine power generation device 1 between the control side and the non-control side in the power unit package 2, when performing maintenance work of each system, the power unit package 2 is moved back and forth between both sides. The workability can be improved.

  Further, an auxiliary tank 50 and a supply tank 51 (hereinafter collectively referred to as “lubricating oil tank”) in the lubricating oil system separate the generator 10 from the engine 9 and end portions in the power unit package 2. Is arranged. That is, in this embodiment, the lubricating oil tank is arranged along the right side surface of the power unit package 2. Specifically, as shown in FIG. 11, the replenishment tank 51 is placed on the auxiliary tank 50 placed on the base 3. As described above, the ventilation performance in the power unit package 2 is improved by arranging the lubricating oil tank.

  That is, in the power unit package 2, air (outside air) is taken in by the ventilation fans 81 and 81 of the ventilation chamber 8 provided at the upper right portion, and outside air is guided from the right side to the left side in the engine room 5. When the power unit P and the radiator unit R are disposed adjacent to each other as shown in FIGS. 1 to 3, etc., the outside air from the engine room 5 passes through the exhaust port 2 b provided on the left side surface of the power unit package 2. A radiator fan 56 in the package 52 is discharged to the outside through the exhaust duct 2c. Further, when the power unit P and the radiator unit R are installed separately as shown in FIG. 5 and the like, the outside air taken in by the ventilation fans 81 and 81 is sent from the engine room 5 to the exhaust port 2b or the power unit package 2.

The passage of outside air taken into the power unit package 2 by 81 is not obstructed, and the ventilation performance in the power unit package 2 can be improved. Furthermore, by disposing the generator 10 at a position separated from the engine 9, it is difficult to be affected by radiant heat from the engine 9, and the temperature rise of the lubricating oil in the lubricating oil tank can be suppressed.

  Further, as described above, there may be a case where two or more engine power generators 1 are installed as shown in FIGS. 4 and 5, for example. In such a case, in order to connect the air start systems of the engines 9 to each other, the base 3 of the power unit package 2 is provided with a communication port 62 that communicates with the air start system. The communication port 62 is branched from a pipe between the air compressor 16 of the air start system and the air tank 18 and connected to the pipe. That is, the air start system can be communicated with the outside through the communication port 62.

  For example, when the power unit P and the radiator unit R are arranged as shown in FIG. 4 in the engine power generation device 1, the communication ports 62 communicate with each other through the pipes 63, so that the air start systems communicate with each other. . In this case, specifically, the communication port 62 in one engine power generator 1 is on the side surface on the front side of the base 3 (see 62a in FIG. 1), and the communication port 62 in the other engine power generator 1 is the base 3 2 (see 62b in FIG. 2), respectively. That is, from the viewpoint of shortening the internal piping from the air start system to the communication port 62 in each engine power generator 1, the communication port 62 provided in the base 3 is located in the vicinity of the air start system (particularly the air tank 18) in each. Preferably, from the viewpoint of shortening the external piping connecting the communication ports 62, when the engine power generators 1 are arranged in parallel to each other as shown in FIG. It is preferable to be provided at a position that opposes. As shown in FIG. 5, when the power unit P and the radiator unit R are separately arranged, the communication port 62 can be provided on the right side surface of each base 3 (see 62c in FIG. 7).

  That is, the communication port 62 provided in the base 3 is determined in consideration of the length of the pipe 63, the position of the exhaust gas boiler 24, and the like, depending on the arrangement when the engine power generator 1 is installed. In addition, the communication port 62 is configured to be plugged with a plug or the like so that communication with the outside is interrupted when the engine power generation device 1 is not used or when only one engine power generator 1 is installed. Airtightness in the air start system is maintained.

  Thus, by providing the communication port 62 communicating with the air start system, for example, when two engine power generators 1 are installed, when the air compressor 16 of one air start system fails for some reason, etc. The other air compressor 16 allows the air tank 18 to be filled with air. That is, the air compressors 16 can be used together. Thereby, it is not necessary to provide a spare air compressor or the like in each air start system, and mutual backup of the air start system becomes possible.

  Further, in the power unit package 2, the air starting system air compressor 16 and the lubricating oil system priming pump 60 are disposed at a position at least separating the generator 10 in the width direction with respect to the control unit 14 in the power unit package 2. Has been. The generator panel 12 and the auxiliary machine panel 13 constituting the control unit 14 are arranged at the right end in the power unit package 2 as shown in FIG. That is, the generator 10 is arranged on the right side of the engine 9 arranged at the substantially central position in the left-right direction in the engine room 5, and the control unit 14 is arranged on the further right side of the generator 10. And with respect to this control unit 14, the air compressor 16 is arrange | positioned in the position (left side position of the engine 9) which separated the generator 10 and the engine 9 in the width direction, and the priming pump 60 separated the generator 10 in the width direction. (Position on the steering side of the engine 9).

  As described above, by disposing the air compressor 16 and the priming pump 60 at positions separated from the control unit 14 in the power unit package 2, electromagnetic noise generated from the air compressor 16 and the priming pump 60 driven by an electric motor or the like. The influence on the control unit 14 can be reduced. Thereby, stable control of the engine power generator 1 by the control unit 14 becomes possible.

  In addition, as described above, the air start system is intensively disposed on the steering side in the power unit package 2, particularly on the left side of the engine 9. Therefore, it is preferable that the air compressor 16, the air dryer 17, and the air tank 18 constituting the air start system are unitized. For example, as shown in FIG. 12, the air compressor 16, the air dryer 17, and the air tank 18 are placed and fixed on one mounting base 64, and this is configured outside the power unit package 2 in advance as an air starting system unit 70. To do. When the devices are arranged in the power unit package 2, the mounting base 64 is placed and fixed on the base 3, whereby the air start system unit 70 is assembled in the power unit package 2, and the pipe 18 a from the air tank 18 is connected to the above-mentioned Connect to the pipe that leads to the air motor.

  Thus, by unitizing the air start system, the air start system can be accommodated in the power unit package 2 in a compact manner, and workability when the air start system is assembled can be improved.

  Incidentally, as shown in FIG. 14, the fuel tank 15 is disposed in the vicinity of and above the feed pump 71 that supplies fuel from the fuel tank 15 to the engine 9. Here, the fuel supply system of the engine 9 including the fuel tank 15 will be described with reference to FIG. The fuel supplied to the engine 9 is stored in a fuel tank 15 which is a so-called fuel dispensing tank. The fuel in the fuel tank 15 is sucked by the feed pump 71 and supplied into the engine 9. At this time, the water from the fuel tank 15 is separated from the water mixed in the fuel through the oil / water separator 72, and fine impurities are removed through the fuel filter 73. The fuel supplied by the feed pump 71 is introduced into a fuel injection pump 74 attached to the engine 9 and is injected into the combustion chamber through the fuel injection valve by the fuel injection pump 74. Excess fuel from the fuel injection pump 74 is returned to the fuel tank 15. The fuel tank 15 is connected to a large-capacity fuel main tank (not shown) buried in the basement, for example. When the amount of fuel in the fuel tank 15 decreases, the fuel tank 15 is replenished from a certain amount. When it increases, it is returned to the main fuel tank. The amount of fuel in the fuel tank 15 is detected and controlled by the generator panel 12 by a level switch 15a provided in the fuel tank 15.

  A fuel tank 15 for storing the fuel supplied to the engine 9 in this way is disposed in the vicinity of the feed pump 71 and above the feed pump 71. Specifically, as shown in FIG. 14, the feed pump 71 is attached to the left side surface of the engine 9, and the fuel tank 15 is disposed on the upper left side of the feed pump 71. The arrangement of the oil / water separator 72 and the fuel filter 73 is as shown in FIG.

  Thus, by arranging the fuel tank 15 in the vicinity of and above the feed pump 71, pressure due to gravity (self-weight) is applied to the fuel guided from the fuel tank 15 to the feed pump 71 disposed below the fuel tank 15. Piping pressure loss from the tank 15 to the feed pump 71 can be reduced, and the suction of fuel from the fuel tank 15 by the feed pump 71 can be assisted.
