  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view showing an internal structure of a vehicle engine room according to an embodiment of the present invention. In the present embodiment, the engine room 10 in which the engine 20 is disposed is provided in front of the vehicle. In FIG. 1, only a part of the components arranged in the engine room 10 is shown. Hereinafter, the vehicle front-rear direction is simply referred to as the front-rear direction, and the vehicle width direction is simply referred to as the left-right direction. Also, the right side in FIG. 1 is simply referred to as the right side, and the left side in FIG. 1 is simply referred to as the left side. FIG. 2 is a perspective view showing the structure around the engine 20. 2, the fan main body 32 and the battery 50 of the fan 30 to be described later are omitted from FIG. FIG. 3 is a front view showing the structure around the engine 20.

  The engine room 10 is partitioned by various frames as vehicle body structures. Specifically, a pair of left and right front side frames 61 and 61 provided at the bottom of the engine room 10 and extending in the front-rear direction and a pair of left and right provided at the upper part of the engine room 10 and extending in the front-rear direction are provided at the vehicle front side portion. Apron upper members 62, 62 and a shroud door upper panel 63 extending left and right across the front ends of the apron upper members 62, 62 are provided.

  In the engine room 10, a high-pressure fuel pump (fuel pump) 28, a cooling fan 30, a resonator 42, an air cleaner 43, and a battery 50 are disposed in addition to the engine 20.

  The engine 20 is disposed in the center of the left and right sides of the engine room 10. The engine 20 is a multi-cylinder engine, and these cylinders are arranged in the front-rear direction. That is, the engine 20 is placed vertically in the engine room 10. In the present embodiment, the engine 20 is a direct injection type in-line four-cylinder engine. An intake manifold 24 and an exhaust manifold (exhaust passage) 26 of the engine 20 are respectively disposed on the left and right of the engine body 21. Specifically, the intake manifold 24 is disposed on the right side of the engine body 21, and the exhaust manifold 26 is disposed on the left side of the engine body 21.

  The high-pressure fuel pump 28 is for supplying high-pressure fuel to an injector provided in the cylinder. As described above, in the present embodiment, the engine 20 is a direct injection engine, and the fuel whose pressure has been increased by the high-pressure fuel pump 28 is directly injected into the cylinder. The high pressure fuel pump 28 is driven by an exhaust camshaft (not shown) of the engine 20. The high-pressure fuel pump 28 is attached to the rear side surface (rear end portion) of the engine body 21 and is connected to the rear end portion of the exhaust camshaft via a pump cam. As described above, the exhaust manifold 26 is provided on the left side of the engine body 21, and the exhaust camshaft is located on the left side portion of the engine body 21. In accordance with this arrangement, the high-pressure fuel pump 28 is arranged on the left side portion of the rear side surface of the engine body 21.

  The cooling fan 30 is for cooling various components in the engine room 10, and sends out cooling air backward to scavenge hot air in the engine room 10 backward. In particular, high-temperature exhaust gas flows in the exhaust manifold 26, and the temperature around the exhaust manifold 26 in the engine room 10 tends to be high. For this reason, there is a risk that the temperature of this portion will increase the heat of the gasket of the head cover, and it is desired that the hot air around the exhaust manifold 26 be more reliably scavenged backward by the cooling fan 30.

  The cooling fan 30 includes a fan shroud 31 and a fan main body 32 accommodated in the fan shroud 31. As shown in FIG. 3, the fan main body 32 has a plurality of wings, and blows air radially backward by the rotation of the wings.

  The cooling fan 30 is disposed below the shroud door upper panel 63 and immediately behind a radiator (not shown) disposed at the front end of the engine room 10. In addition, the cooling fan 30 is disposed substantially in the center of the left and right sides of the engine room 10 and is located in front of the engine 20. The left and right widths of the fan main body 32 are approximately the same as the left and right widths of the engine main body 21.

  In this vehicle, the cooling fan 30 is operated even after the vehicle stops. Specifically, even after the vehicle is stopped, if the temperature in the engine room, specifically, the temperature of the engine cooling water is equal to or higher than a predetermined temperature, the cooling fan 30 is operated.

  Both the resonator 42 and the air cleaner 43 are intake system components.

  The air cleaner 43 is disposed between the cooling fan 30 and the engine 20 and immediately behind the cooling fan 30. The cooling fan 30, the air cleaner 43, and the engine 20 are arranged in the front-rear direction. In this embodiment, the air cleaner 43 is a substantially rectangular parallelepiped box, and the width in the left-right direction is set to be substantially the same as the left-right width of the engine body 21 and the left-right width of the fan body 32, as shown in FIG. As shown, they overlap each other in front view. In addition, the air cleaner 43 is disposed in an upper portion in the engine room 10. Specifically, the air cleaner 43 is located above the center of the fan main body 32 of the cooling fan 30. The air cleaner 43 is connected to the intake manifold 24 via the intake pipe 44. Specifically, the intake pipe 44 extends from the rear right side portion of the air cleaner 43 in the right rear direction and is connected to the intake manifold 24.

  The air cleaner 43 is formed of a relatively soft member such as resin. Therefore, in the present vehicle, the air cleaner 43 is disposed in front of the engine 20 as described above, so that the collision load is prevented from being transmitted to the engine 20 at the time of the vehicle front collision. That is, since the air cleaner 43 is deformed and absorbs an impact at the time of a frontal collision of the vehicle, a collision load applied to the engine 20 is suppressed to a small level. In particular, in the present embodiment, as described above, since the left-right width of the air cleaner 43 is set to be approximately the same as the left-right width of the engine body 21, the air cleaner 43 can more reliably transmit the collision load to the engine body 21. It is suppressed. The battery 50 is disposed on the right side of the air cleaner 43.

  The resonator 42 is provided in the middle of the intake duct 41 that extends forward from the left side surface of the air cleaner 43 and opens near the shroud upper panel 63. In the present embodiment, the resonator 42 is composed of two tubular members (the tips are closed), and extends outward from the surface of the intake duct 41.

  The intake duct 41 includes a downstream portion 41b that has a resonator 42 and is connected to the air cleaner 43, and a portion 41a that is further upstream than the downstream portion 41b.

  The downstream portion 41b of the intake duct 41 extends horizontally from the air cleaner 43 to the left and then curves upward and obliquely to the right. The downstream portion 41b is a circular pipe. The resonator 42 is provided in a curved portion of the downstream portion 41 b of the intake duct 41 and is formed integrally with the downstream portion 41 b of the intake duct 41.

  The upstream portion 41a of the intake duct 41 extends forward while curving from the front end of the downstream portion 41b. The upstream portion 41 a of the intake duct 41 is attached to the vehicle body by attaching a front end portion thereof to the shroud door upper panel 63 by a bracket 45.

  On the other hand, the downstream portion 41b of the intake duct 41, which is integrally formed with the resonator 42 and connected to the left side surface of the air cleaner 43, has a downstream end portion positioned between the air cleaner 43 and the resonator 42 by the mounting bracket 70. By being attached to the panel 63, it is attached to the vehicle body. As described above, the resonator 42 and the downstream portion 41b of the intake duct 41 are integrally formed. Therefore, the mounting bracket 70 functions as a mounting bracket for mounting the downstream portion 41b of the intake duct 41 to the vehicle body, and also functions as a mounting bracket for mounting the resonator 42 to the vehicle body.

  The mounting bracket 70 extends upward and forward from the upper surface of the intake duct 41 toward the shroud door upper panel 63. Here, as described above, the air cleaner 43 and the engine main body 21 have substantially the same left and right widths and overlap each other when viewed from the front. Further, the air cleaner 43 is positioned above the center of the fan body 32 of the cooling fan 30. The mounting bracket 70 is provided at the downstream end portion of the downstream portion 41 b of the intake duct 41 connected to the left side surface of the air cleaner 43 and extends upward. Therefore, as shown in FIG. 3 and the like, the mounting bracket 70 is located above the center of the upper and lower sides of the fan main body 32, and is located in front of the exhaust manifold 26 disposed on the left side of the engine 20, so that the exhaust manifold 26 overlaps with the front view.

  Next, the detailed structure of the mounting bracket 70 will be described with reference to FIGS.

  In the present embodiment, the mounting bracket 70 and the downstream portion 41 b of the intake duct 41 including the resonator 42 are formed integrally with each other, and are configured as an integrated resonator assembly 80.

  FIG. 4 is a plan view around the mounting bracket 70. FIG. 5 is a perspective view of the resonator assembly 80. 6 and 7 are a front view and a rear view of the resonator assembly 80, respectively. 8 and 9 are side views of the resonator assembly 80, respectively. 10 is a cross-sectional view taken along line XX of FIG.

  The mounting bracket 70 includes a plate-like left side plate (first side wall, peripheral wall) 71, right side plate (second side wall, peripheral wall) 72, passage top plate (upper wall, peripheral wall) 73, back plate 74, and mounting plate. 75 and a guide plate (guide portion) 76.

  The left side plate 71 and the right side plate 72 are plate-like members that extend upward from the upper surface of the intake duct 41 and extend in the front-rear direction along the upper surface. These plates 71 and 72 are arranged parallel to each other on the left and right. In the present embodiment, the plates 71 and 72 extend vertically.

  As shown in FIG. 5, FIG. 8, etc., of the left side plate 71 and the right side plate 72, the right side plate 72 arranged on the right side, that is, the inner side in the vehicle width direction and closer to the cooling fan 30 is the outer periphery of the intake duct 41. It extends from substantially the same position as the front end of the surface to a position ahead of the rear end of the intake duct 41. As described above, the downstream portion 41b of the intake duct 41 is a circular pipe. Therefore, the lower edge of the right side plate 72 has an arc shape. The height of the front edge of the lower edge of the right side plate 72 is located below the height of the rear edge. In the present embodiment, as shown in FIG. 8, the right side plate 72 extends from the front end of the outer peripheral surface of the intake duct 41 to the approximate center between the upper end and the rear end of the outer peripheral surface of the intake duct 41.

  On the other hand, the left side plate 71 disposed on the left side, that is, on the outer side in the vehicle width direction and far from the cooling fan 30 has substantially the same configuration as the right side plate 72. Extends further forward. Specifically, the left side plate 71 extends from the same position as the rear edge of the right side plate 72 to a position ahead of the front edge of the right side plate 72, that is, the front end of the outer peripheral surface of the intake duct 41 in the front-rear direction. The left side plate 71 extends forward so that the lower edge of the portion extending forward from the front end of the outer peripheral surface of the intake duct 41 extends uniformly at the same height as the front end of the outer peripheral surface of the intake duct 41. . As shown in FIG. 6 and the like, the left side plate 71 is provided in a portion of the intake duct 41 slightly above the portion where the right side plate 72 is provided. That is, the difference in height between the lower edges of the side plates 71 and 72 is very small.

  The mounting plate 75 is a plate-like member that extends horizontally between the right side plate 72 and the upper edge of the left side plate 71 as shown in FIGS. A mounting hole 75 a is formed at the front end of the mounting plate 75. The mounting plate 75 extends to the shroud door upper panel 63 and is fixed to the shroud door upper panel 63 by bolts or the like inserted through the mounting holes 75a. By this fixing, the resonator assembly 80 is fixed to the vehicle body. In the present embodiment, the upper ends of the right side plate 72 and the left side plate 71 extend to the vicinity of the shroud upper panel 63 according to the mounting plate 75.

  As shown in FIG. 8, the passage top plate 73 is a rectangular plate-like member that extends horizontally across the upper and lower intermediate portions of the right side plate 72 and the upper and lower intermediate portions of the left side plate 71. By this passage top plate 73, a space between the right side plate 72 and the left side plate 71 is partitioned vertically. The passage top plate 73 extends slightly forward from the rear edge of each side plate 71, 72 to the front edge of the left side plate 71. Moreover, the passage top plate 73 extends slightly forward and downward.

  The back plate 74 is a plate-like member extending between the rear edges of the upper side portion of the right side plate 72 and the left side plate 71 with respect to the passage top plate 73. In the present embodiment, for the purpose of weight reduction, the upper rear portions of the right side plate 72 and the left side plate 71 are cut in an arc shape, and the back plate 74 extends vertically upward in accordance with this shape. Curved forward after.

  In this way, a portion of the mounting bracket 70 above the passage top plate 73 is surrounded by the right side plate 72 and the left side plate 71, and the passage top plate 73, the attachment plate 75, and the back plate 74, A space that opens only forward is formed.

  On the other hand, a portion of the mounting bracket 70 below the passage top plate 73 is surrounded by the passage top plate 73, the left side plate 71, the right side plate 72, and the outer peripheral surface of the intake duct 41 in the front-rear direction. An air guide passage 79 extending to open in the front-rear direction is formed. Specifically, the front edge of the right side plate 72, the portion of the left side plate 71 facing the front edge of the right side plate 72, and the front surface of the outer periphery of the intake duct 41 located between the right side plate 72 and the left side plate 71. A portion surrounded by the edge and a portion of the passage top plate 73 facing the front edge of the outer peripheral surface of the intake duct 41 is an introduction port 79a, and the right side plate 72, the left side plate 71, and the rear edge of the passage top plate 73 A portion surrounded by the outer peripheral surface of the intake duct 41 and a portion located between these rear edges is defined as a discharge port 79b, and an air guide passage 79 extending forward and backward between the introduction port 79a and the discharge port 79b is formed. Is formed. The left side plate 71 extends forward from the air guide port 79a, and the passage top plate 73 extends from the air guide port 79a to the front side.

  In addition, as described above, the lower end of the rear edge of the right side plate 72 that defines the discharge port 79b is higher than the lower end of the front edge of the right side plate 72 that defines the introduction port 79a. It is smaller than the opening area of the mouth 79a. As described above, the passage top plate 73 is tilted forward and downward, but is tilted so as to ensure the relationship of the opening areas.

  As shown in FIGS. 5 and 6, the guide plate 76 is a plate-like member that is inclined forward and obliquely downward and provided in front of and below the introduction port 79 a. In the present embodiment, the guide plate 76 extends slightly forward from the lower end of the introduction port 79a and then extends obliquely downward to the lower side.

  As described above, in the present embodiment, the fan main body 32 is positioned above the center of the upper and lower sides, and is positioned in front of the exhaust manifold 26 disposed on the left side of the engine 20. An air guide passage 79 that opens in the front-rear direction and extends in the front-rear direction is formed in the mounting bracket 70 that is disposed so as to overlap each other. Therefore, when the cooling air sent radially from the cooling fan 30 flows into the introduction port 79a of the air guide passage 79, the direction of the cooling air is deflected rearward, and the rearward direction, that is, toward the exhaust manifold 26 from the discharge port 79b. Discharged. Therefore, the hot air around the exhaust manifold 26 is more surely scavenged backward by the cooling air, and the heat damage of various devices in the engine room 10 is suppressed.

  Specifically, when the mounting bracket is composed of a simple plate-like member having no passage on the inside, the cooling air sent from the cooling fan 30 is upward as shown by the broken line arrows in FIGS. However, in this embodiment, as shown by the solid line arrows, the cooling air that is directed upward and outward in the vehicle width direction is guided to the exhaust manifold 26. The passage 79 can be guided to the exhaust manifold 26 side. Further, compared to the case where the mounting bracket 70 is configured by a simple plate member, the cross-sectional secondary moment of the mounting bracket 70 can be increased, and the rigidity of the mounting bracket 70, that is, the mounting rigidity can be increased.

  In particular, in the present embodiment, as described above, the high-pressure fuel pump 28 is disposed on the left side portion of the engine body 21 provided with the exhaust manifold 26. Therefore, the heat damage of the high-pressure fuel pump 28 can be more reliably suppressed, and stable engine performance can be obtained. That is, when the high-pressure fuel pump 28 becomes hot and bubbles are generated in the fuel, there is a risk that a so-called vapor lock phenomenon may occur in which the fuel cannot be properly injected. Fuel injection control can be performed.

  In the present embodiment, the opening area of the introduction port 79a is set larger than the opening area of the discharge port 79b. Therefore, the speed of the cooling air is increased in the air guide passage 79 so that the cooling air having a high flow velocity can be supplied around the exhaust manifold 26, and the hot air around the exhaust manifold 26 can be scavenged more reliably to the rear. it can.

  In the present embodiment, the left side plate 71 located on the outer side in the vehicle width direction than the cooling fan 30 extends forward from the right side plate 72. Therefore, the cooling air flowing outward in the vehicle width direction can be caught by the left side plate 71 and guided into the air guide passage 79, and more cooling air can be supplied to the exhaust manifold 26.

  In the present embodiment, the passage top plate 73 constituting the upper wall of the air guide passage 79 extends forward from the introduction port 79a. Therefore, the upward cooling air can be caught by the passage top plate 73 and guided into the air guide passage 79, and more cooling air can be supplied to the exhaust manifold 26.

  In the present embodiment, a guide plate 76 that is inclined obliquely downward and forward is provided below and in front of the introduction port 79a. For this reason, the guide plate 76 can guide the cooling air to pass under the inlet 79 a into the air guide passage 79, and supply more cooling air to the exhaust manifold 26.

  The present invention is not limited to the above-described embodiment, and can be substituted without departing from the scope of the claims.

  For example, in the above-described embodiment, the case where the air guide passage 79 is configured by the left and right side plates 71 and 72, the outer peripheral surface of the intake duct 41, and the passage top plate 73 is illustrated as a substantially rectangular cross section. The passage 79 only needs to be surrounded by a peripheral wall, and may have a circular cross section.

  In addition, the length in the front-rear direction of the peripheral wall surrounding the air guide passage 79 may be the same. However, as described above, if the left side plate 71, that is, the portion on the outer side in the vehicle width direction of the peripheral wall is configured to extend forward from the inner portion, the cooling air directed toward the outer side in the vehicle width direction is guided into the air guide passage 79. More cooling air can be supplied to the exhaust manifold 26. Further, as described above, when the mounting bracket 70 is positioned above the center of the cooling fan 30, the upper portion of the passage top plate 73, that is, the peripheral wall, extends forward from the lower portion. By doing so, it is possible to guide the upward cooling air into the air guide passage 79 and supply more cooling air to the exhaust manifold 26.

  Further, the member attached to the mounting bracket 70 is not limited to the resonator assembly 80.

  Further, the mounting bracket 70, the intake duct 41, and the resonator 42 may not be formed integrally. However, if these are integrated, these rigidity can be mutually improved.
