【考案の詳細な説明】
本考案は自動車用内燃機関の吸気構造に関する
ものである。[Detailed Description of the Invention] The present invention relates to an intake structure for an internal combustion engine for an automobile.
自動車の騒音対策として排気騒音に加え吸気騒
音の低減が要望されるようになつて来ており、吸
気騒音低減にはエアクリーナの吸気通路即ちエア
ホーンを長くするのが効果的である。 As noise countermeasures for automobiles, it has become necessary to reduce intake noise in addition to exhaust noise, and an effective way to reduce intake noise is to lengthen the air cleaner's intake passage, that is, the air horn.
ところがスペース上の制約があつてエアクリー

部材側に伝わり車室内騒音を増大させると言う不
具合が生じる。 However, due to space constraints, the air horn of the air cleaner cannot be made sufficiently long. Therefore, some vehicles have adopted a method in which the air horn is connected to a vehicle body structural member with a closed cross section such as a frame, and a part of the vehicle body structural member is used as an intake passage (see, for example, Japanese Utility Model Publication No. 58307/1983). In this case, a problem arises in that vibrations of the internal combustion engine are transmitted to the vehicle body structural members via the air horn, increasing the noise inside the vehicle.
本考案は上記のような問題をすべて解消し得る
吸気構造を提供するもので、以下附図実施例につ
き説明する。 The present invention provides an intake structure that can solve all of the above-mentioned problems, and will be described below with reference to the accompanying drawings.

よう構成したものである。 In the present invention, the upper frame 41 of the cross-flow radiator 4 is configured to have a closed cross section, and the tip of the air horn 31 of the air cleaner 3 is connected to the opening 41a at one end of the closed cross section upper frame 41 through the connecting duct 6, so that the intake air is The air is drawn into the air cleaner 3 from the air horn 31 through the upper frame 41 through the opening 41b at the other end of the upper frame 41.

具合は全く生じることがない。 According to the present invention configured in this way, since the upper frame 41 of the radiator 4 serves as the intake passage, the overall length of the intake passage can be significantly increased, and intake noise can be significantly reduced, and the engine 1
Even if vibrations from the air cleaner 3, air horn 31, etc. are transmitted to the radiator 4, the radiator 4 is originally supported by the vehicle body A via the elastic members 5, 5', and the vibrations are transmitted to the radiator 4 via the elastic members 5, 5'. Absorption is reduced at 5', and no problems such as increasing noise inside the vehicle occur.

きる。 In the embodiment shown in the accompanying drawings, the radiator has an inlet tank 43 and an outlet tank 4 on both sides.
This example shows an example using a cross flow radiator with a cross-flow radiator that allows the coolant to flow horizontally.
The Atsupa frame 41 is used as the intake passage, but in the case of a radiator that has Atsupa and lower tanks above and below the radiator and allows the coolant to flow from top to bottom, either the left or right frame is used as a closed section. In the case of the above-mentioned cross flow radiator, the lower frame 4 may be used as the intake passage depending on the mounting location or mounting orientation of the radiator, such as when it is installed horizontally in the upper part of the engine room.
2 can also be made into a closed cross section and used as an intake passage.
