- a bulge portion that is raised and raised at an appropriate position on the inner surface of the wall portion constituting the surge tank is provided, and a gas introduction portion for introducing a gas containing water vapor at an appropriate position other than the bulge portion on the inner surface of the wall portion (
- a gas introduction hole for introducing a gas containing water vapor at an appropriate position other than the bulge portion on the inner surface of the wall portion
- a negative pressure supply path for taking out the intake negative pressure in the surge tank
- the gas introduction part and the opening of the negative pressure supply path are separated by a partition wall, but the gas introduction part and the opening of the negative pressure supply path are provided adjacent to each other. Yes.
- the gas supplied from the gas introduction part easily flows into the negative pressure supply path due to the entrainment flow generated in the surge tank.
- the gas flows into the negative pressure supply path due to the entrainment flow, and the negative pressure supply path may be clogged due to freezing of the mist-like fluid or vapor contained in the gas.
- the intake manifold described in Patent Document 2 is provided with a guide groove that suppresses the intrusion of water droplets into the negative pressure supply path in the raised portion.
- the guide groove due to the entrainment flow in the surge tank Therefore, there is a risk that water droplets that circulate while avoiding the negative pressure supply path will diffuse. Therefore, the diffused water droplets are likely to flow into the negative pressure supply path due to the entrainment flow, and the negative pressure supply path may be clogged due to freezing.
- the present invention has been made in view of the above-described problems, and suppresses the inflow of fuel components and moisture contained in the gas introduced from the gas introduction portion to the negative pressure supply path, thereby blocking the negative pressure supply path.
- the purpose is to suppress.
- a first characteristic configuration of an intake manifold according to the present invention is an intake manifold having a surge tank to which an intake passage for air supplied to an internal combustion engine is connected, and communicates with the intake passage or the surge tank.
- a gas introduction part that introduces a gas containing a fuel component into the surge tank; and communicates upstream of the gas introduction part in the intake flow path or the surge tank with respect to the flow direction of the air.
- a negative pressure supply path for supplying a negative pressure to the outside, and the negative pressure supply path passes through the expansion chamber having a cross-sectional area larger than the cross-sectional area of the negative pressure supply path, or the intake flow path or the It is connected to the surge tank.
- the negative pressure supply path is provided upstream of the gas introduction part in the air flow direction, the gas introduced from the gas introduction part is affected by the entrainment flow in the surge tank and has a negative pressure. Inflow into the supply path can be suppressed. That is, clogging of the negative pressure supply path due to the fuel component and moisture contained in the gas and blockage of the negative pressure supply path due to freezing thereof can be suppressed, and negative pressure can be supplied to the outside in a timely manner. Since the negative pressure supply path only needs to be arranged upstream of the gas introduction portion in the air flow direction, the arrangement location of the negative pressure supply path can be changed according to the mounting space of each vehicle, and the degree of design freedom is improved.
- the suction force due to the negative pressure at the inlet of the expansion tank on the surge tank side is smaller than the suction force due to the negative pressure in the negative pressure supply path. small. Therefore, compared with the case where no expansion chamber is provided, the fuel component and moisture contained in the gas are less likely to flow into the negative pressure supply path.
- the negative pressure supply path is substantially extended by the expansion chamber having a large cross-sectional area, even if the fuel component and moisture flow into the expansion chamber, they adhere to the wall surface of the expansion chamber and go to the negative pressure supply path. Inflow of fuel components and moisture can be suppressed. As a result, clogging of the negative pressure supply path due to the fuel component and moisture contained in the gas and blockage of the negative pressure supply path due to freezing thereof are further suppressed.
- a second characteristic configuration of the intake manifold according to the present invention is that the expansion chamber has a first opening communicating with the negative pressure supply path, and a second opening communicating with at least one of the intake flow path and the surge tank. And the opening area of the second opening is set larger than the opening area of the first opening.
- the opening area of the second opening is small, so the fuel component contained in the gas in the second opening.
- clogging due to adhesion of moisture and freezing of the negative pressure supply path due to blockage are likely to be induced.
- the second opening of the expansion chamber has a larger opening area than the first opening, so that the second opening is clogged by the fuel component and moisture contained in the gas, or they are frozen. It is difficult for the second opening to be blocked.
- the first opening is separated from the gas introduction part through the expansion chamber, the first opening is also clogged with the fuel component and moisture contained in the gas and the first opening due to freezing thereof. Blockage of the part is suppressed. As a result, clogging of the negative pressure supply path due to the fuel component and moisture contained in the gas and blockage of the negative pressure supply path due to freezing thereof are suppressed, and negative pressure can be supplied to the outside in a timely manner.
- a third characteristic configuration of the intake manifold according to the present invention is that the expansion chamber has the first opening and the first piece integrally formed with the negative pressure supply path, and the second opening has the second opening. It is in the point formed from the piece.
- the expansion chamber is formed by a combination of the first piece and the second piece, and is provided in the intake manifold with a simple structure. That is, the expansion chamber can form a negative pressure supply channel that is easily supplied from the negative pressure supply channel by assembling the first piece and the second piece.
- the negative pressure supply path is provided in the first piece, the welding area of the first piece and the second piece is reduced compared to the case where the negative pressure supply path is configured with the first piece and the second piece, In addition, poor welding in the negative pressure supply path cannot occur. If the extending direction of the negative pressure supply path is changed according to each vehicle, the negative pressure supply path communicating with the negative pressure supply path can be shortened, and a small intake manifold can be obtained. Furthermore, since it is not necessary to change the shape of the second piece according to each vehicle, it can be used in common regardless of the type of vehicle.
- the shape of the first piece is a shape that becomes narrower from the end that becomes the boundary with the second piece toward the first opening, and the first piece is In the case of molding by injection molding, the first piece can be easily taken out from the mold.
- a fourth characteristic configuration of the intake manifold according to the present invention is that, in the second opening, an opening dimension in a direction orthogonal to the air flow direction is set shorter than an opening dimension in the air flow direction.
- the opening dimension in the direction perpendicular to the air flow direction is shorter than the opening dimension in the air flow direction in the second opening. That is, the length of the edge of the second opening, which is the source of airflow noise, on the upstream side in the air flow direction is shortened, so that the air supplied to the internal combustion engine is reduced from entering the expansion chamber. As a result, the vortex generated at the edge of the second opening on the upstream side in the air flow direction is reduced, and the generation of airflow noise can be suppressed.
- the second opening has a longitudinal direction extending in the air flow direction and a width direction orthogonal to the air flow direction.
- the length of the edge of the second opening in the width direction is that the upstream side in the air flow direction is shorter than the downstream side in the air flow direction.
- the length of the edge of the second opening in the width direction is shorter on the upstream side in the air flow direction than on the downstream side. Therefore, when considering the total length of the edge of the second opening in the width direction as constant, compared with the case where the upstream side is longer than the downstream side while securing the opening area of the second opening. Thus, the amount of vortex generated at the upstream edge is reduced. Therefore, generation of airflow noise can be further suppressed.

- the air-fuel mixture includes PCV gas and EGR gas, which will be described later, in addition to air.
- an air current in which the air current of the air-fuel mixture swirls in the surge tank 2 (hereinafter referred to as an entrained flow) It is designed to be.
- the intake manifold 1 has a vacuum pressure supply passage 3 (negative pressure) for supplying the vacuum pressure (negative pressure) in the surge tank 2 to a vacuum pressure actuator (not shown) and a brake booster (not shown). Pressure supply path) and a gas introduction part 4 for introducing gas into the surge tank 2.
- the gas introduction unit 4 communicates with the upstream intake passage 21 to introduce a PCV gas containing a liquid such as a fuel component and moisture, and communicates with the surge tank 2 to communicate a liquid such as a fuel component and moisture.
- a second gas introduction part 42 for introducing EGR gas containing.
- the vacuum pressure supply path 3 communicates with the upstream side of the upstream intake path 21 from the gas introduction part 4 in the air flow direction, and is connected to the upstream intake path 21 via the expansion chamber 5.
- the vacuum pressure in the surge tank 2 is supplied.
- the vacuum pressure supply path 3 includes a first vacuum pressure supply path 31 to which a vacuum pressure supply port (not shown) is connected from a vacuum pressure actuator, and a first vacuum pressure supply port to which a vacuum pressure supply port is connected from a brake booster.
- a double vacuum pressure supply passage 32 is shown in FIG. 2, the vacuum pressure supply path 3 includes a first vacuum pressure supply path 31 to which a vacuum pressure supply port (not shown) is connected from a vacuum pressure actuator, and a first vacuum pressure supply port to which a vacuum pressure supply port is connected from a brake booster.
- a double vacuum pressure supply passage 32 is shown in FIG. 2, the vacuum pressure supply path 3 includes a first vacuum pressure supply path 31 to which a vacuum pressure supply port (not shown) is connected from a vacuum pressure actuator, and a first vacuum pressure supply port to which a vacuum pressure supply port is connected from a brake booster.
- the expansion chamber 5 includes a first expansion chamber 51 provided on the welding surface 10a of the upper piece 1a and a second expansion chamber 52 provided on the welding surface 10b of the middle piece 1b. Is done.
- the first expansion chamber 51 has a first opening 51 a that communicates with the vacuum pressure supply path 3
- the second expansion chamber 52 has a second opening 52 a that communicates with the upstream intake passage 21.
- the first gas introduction part 41 is also composed of a first gas introduction channel 41a provided on the welding surface 10a and a second gas introduction channel 41b provided on the welding surface 10b.
- the 3rd opening part 41c which the 2nd gas introduction flow path 41b and the upstream intake flow path 21 connect is provided in the air flow direction downstream rather than the 2nd opening part 52a.
- the inflow of the PCV gas introduced from the first gas introduction part 41 into the vacuum pressure supply path 3 can be suppressed.
- the opening area of the second opening 52a is larger than that of the first opening 51a so that the vacuum pressure in the surge tank 2 can be smoothly supplied from the vacuum pressure supply path 3 to the vacuum pressure actuator or the like. For this reason, blockage of the second opening 52a due to freezing of the fuel component and moisture contained in the gas is suppressed, and the vacuum pressure in the surge tank 2 can be supplied from the vacuum pressure supply path 3 in a timely manner.
- the expansion chamber 5 has a larger supply passage area for the vacuum pressure than the vacuum pressure supply passage 3. That is, the cross-sectional area of the expansion chamber 5 is larger than the cross-sectional area of the vacuum pressure supply path 3.
- the shape of the expansion chamber 5 is such that the supply path area of the vacuum pressure increases as it goes from the first opening 51a to the second opening 52a. That is, since the suction force when supplying the vacuum pressure exerted on the surge tank 2 to the vacuum pressure actuator or the like is reduced, the inflow of the fuel component and moisture contained in the gas into the vacuum pressure supply path 3 can be suppressed.
- the surface 53 on the downstream side in the air flow direction is laid down toward the upstream side in the air flow direction as shown in FIG. Therefore, when the vacuum pressure exerted on the surge tank 2 is supplied to the vacuum pressure actuator, the air flow accompanying the negative pressure supply is guided to the surface 53 and smoothly merges with the air flowing through the upstream intake passage 21. Therefore, turbulence is unlikely to occur in the expansion chamber 5. As a result, the fuel component and moisture are not easily drawn into the expansion chamber 5, and clogging of the vacuum pressure supply path 3 can be prevented more reliably.
- the second opening 52 a has an edge 520 at the boundary with the upstream intake passage 21.
- the second opening 52a is formed so that the opening dimension B in the direction orthogonal to the air flow direction is shorter than the opening dimension A in the air flow direction. That is, the shape of the second opening 52a is a shape in which the direction extending in the air flow direction is the longitudinal direction and the direction extending perpendicular to the air flow direction is the width direction.
- the edge portion 520 on the upstream side in the air flow direction of the second opening 52a which is a source of airflow noise, is shortened, so that the amount of air flowing into the expansion chamber 5 is reduced. Therefore, the generation of the vortex generated at the edge 520 on the upstream side of the second opening 52a in the air flow direction is reduced, and the generation of the airflow sound due to the flowing air can be suppressed.
- FIG. 3 (b) and 3 (c) are modified examples of FIG. 3 (a).
- the edge 520b upstream in the air flow direction is shorter than the edge 520a downstream in the air flow direction. Is formed.
- the edge 520a on the downstream side in the air flow direction extends in a direction perpendicular to the air flow direction so as to include a curve. Accordingly, the edge portion 520a on the downstream side in the air flow direction is longer than that in the case of FIG. 3A and has a shape including a curve. Therefore, since the opening area of the 2nd opening part 52a can be ensured, the length direction of the edge part 520b can be shortened, and generation
- the edge portion 520d on the upstream side in the air flow direction from the edge portion 520c on the downstream side in the air flow direction. Is formed short. Since the edge 520d on the upstream side in the air flow direction is shorter than that in FIG. 3A, the opening area of the second opening 52a decreases from the edge 520c toward the edge 520d.
- the edge portion 520d has a shorter length than that in FIG. 3 (a), so that airflow noise is generated by the turbulent air flow due to the flowing air and the edge portion 520d. Is further suppressed.
- the 2nd opening part 52a is exhibiting the shape containing a curve, it is not limited to this structure.
- the shape of the second opening 52a may be an elliptical shape.
- the first expansion chamber 51 and the vacuum pressure supply path 3 are integrally molded. From this, the location where the vacuum pressure supply path 3 communicates with the first expansion chamber 51 can be determined at the design stage.
- parts that perform various functions mounted on vehicles are increasing, and space for mounting intake manifolds is limited.
- the direction of the vacuum pressure supply path 3 to which the vacuum pressure supply port is connected can be changed according to the vehicle to be mounted. Therefore, the intake manifold 1 of the present embodiment can be mounted on various vehicles, and the intake manifold 1 can be downsized.
- the vacuum pressure supply passage 3 communicating with the first expansion chamber 51 is formed by hollow molding or the like. That is, when the upper piece 1a is injection-molded, the first expansion chamber 51 and the vacuum pressure supply path 3 can be formed in a process of pouring resin. Accordingly, the location, size and number of the vacuum pressure supply passages 3 can be determined with a small number of steps, and the upper piece 1a can be formed with a simple design.
- the first gas introduction part 41 is also integrally formed with the first gas introduction channel 41a, and the first gas introduction part 41 is formed by hollow molding or the like. And the direction of the 1st gas introduction part 41 to which the PCV gas introduction port which introduces PCV gas is connected can be changed according to the vehicles carrying.
- the vacuum pressure supply path 3 is arranged upstream of the gas introduction part 4 in the air flow direction, so that the fuel component and moisture contained in the gas due to the entrainment flow of the surge tank 2 Can be prevented from flowing into the vacuum pressure supply passage 3. That is, clogging (blocking) of the vacuum pressure supply path 3 due to freezing of fuel components and moisture can be suppressed. Furthermore, since the vacuum pressure supply path 3 supplies the vacuum pressure in the surge tank 2 to the vacuum pressure actuator or the like via the expansion chamber 5, the above-described effects can be improved.
- the expansion chamber 5 is formed by welding the welding surface 10a and the welding surface 10b, the expansion chamber 5 can be disposed in the intake manifold 1 without adopting a complicated structure.
- the arrangement location and the number of parts of the gas introduction part 4 are not limited to the above-described embodiment. Any configuration that can distribute and supply PCV gas, EGR gas, and the like introduced from the gas introduction unit 4 to each downstream intake passage 22 may be used.
- the vacuum pressure supply path 3 is configured to communicate with the upstream intake flow path 21, but is not limited thereto. As long as it is configured to communicate with the upstream side of the gas introduction unit 4, the surge tank 2 may be communicated. However, in this case, the vacuum pressure supply path 3 needs to communicate with a portion of the surge tank 2 where air flows in one direction from the upstream side to the downstream side.
