Description

本発明は、内燃機関において、吸気流動（スワール流及び／又はタンブル流）を制御する吸気流動制御弁に関する。   The present invention relates to an intake flow control valve that controls intake flow (swirl flow and / or tumble flow) in an internal combustion engine.

内燃機関の吸気流動制御弁として、特許文献１に記載されているように、吸気通路内の通路壁近傍に吸気流れ方向と直交する方向に配置される弁軸に、平板状の弁体の基端部を取付け、前記弁体の先端部側の回動位置により吸気流動を制御するものがある。
特開２００３−２０６７６１号公報 As described in Patent Document 1, as an intake flow control valve for an internal combustion engine, a flat valve body is mounted on a valve shaft disposed in a direction perpendicular to the intake flow direction in the vicinity of a passage wall in the intake passage. There is a type in which an end portion is attached and the intake air flow is controlled by the rotation position on the tip end side of the valve body.
JP 2003-206761 A

ところで、吸気流動制御弁は、全閉位置（閉方向に最も回動させた位置）とすることにより、吸気流動を最大にすることができるが、全閉位置において、弁体の先端部が吸気通路壁に当たるようにすると、弁体が破損したり、ねじ締結の場合にねじの緩みが発生する恐れがある。このため、全閉位置において、弁体の先端部と吸気通路壁との間に隙間を設けており、この隙間のため、吸気流動の強化に限界があった。   By the way, the intake flow control valve can maximize intake flow by setting it to the fully closed position (position most rotated in the closing direction). If it touches the passage wall, the valve element may be damaged, or the screw may be loosened when the screw is fastened. For this reason, in the fully closed position, a gap is provided between the front end portion of the valve body and the intake passage wall. Due to this gap, there is a limit to the enhancement of the intake flow.

本発明は、このような実状に鑑みてなしたもので、吸気流動制御弁の全閉位置で、弁体の先端部と吸気通路壁との隙間をなくして、吸気流動をより強化できるようにすることを目的とする。   The present invention has been made in view of such a situation, and at the fully closed position of the intake flow control valve, the clearance between the tip of the valve body and the intake passage wall can be eliminated to further enhance the intake flow. The purpose is to do.

このため、本発明では、吸気通路壁に、弁体の全閉位置で、弁体の先端部と当接することにより、当接部をシールする弾性シール部材を設ける構成とする。   For this reason, in this invention, it is set as the structure which provides the elastic seal member which seals a contact part by contact | abutting with the front-end | tip part of a valve body in the fully closed position of a valve body in an intake passage wall.

本発明によれば、弾性シール部材によりシール機能を発揮させることで、全閉位置で、弁体の先端部と吸気通路壁との間の隙間をなくして、吸気流動を大幅に強化できる。   According to the present invention, by exhibiting the sealing function by the elastic seal member, the gap between the tip of the valve body and the intake passage wall can be eliminated at the fully closed position, and the intake flow can be greatly enhanced.

以下に本発明の実施の形態を図面に基づいて説明する。
図１は本発明の一実施形態を示す断面図（図２のＢ−Ｂ矢視断面図）、図２は図１のＡ矢視図である。
吸気流動制御弁は、吸気マニホールド１の下流側端部（シリンダヘッドの吸気ポートとの接続部）に配置される。当該部位の吸気マニホールド１は、内部に略矩形断面の吸気通路２を形成し、図１で右側が吸気流れ方向上流側、左側が吸気流れ方向下流側である。 Embodiments of the present invention will be described below with reference to the drawings.
1 is a cross-sectional view (a cross-sectional view taken along the line B-B in FIG. 2) showing an embodiment of the present invention, and FIG. 2 is a view taken along the arrow A in FIG.
The intake flow control valve is disposed at the downstream end portion of the intake manifold 1 (connection portion with the intake port of the cylinder head). The intake manifold 1 at this portion forms an intake passage 2 having a substantially rectangular cross section therein, and the right side in FIG. 1 is the upstream side in the intake flow direction and the left side is the downstream side in the intake flow direction.

吸気通路２の矩形断面の底面側の通路壁には、吸気流動制御弁の開弁時の格納空間３を形成し、その格納空間３の吸気流れ方向上流側に、吸気流れ方向と直交する方向に、吸気流動制御弁の弁軸４を配置してある。尚、吸気流動制御弁（弁体）は、各気筒毎に設けられるが、弁軸４は共通であり、図示しないモータにより回動される。
吸気流動制御弁は、前記弁軸４（弁体５を取付ける所では半円状の断面）に、平板状の弁体５の基端部を締結手段としてのねじ６により取付けてなり、弁体５の先端部が弁軸４に対し吸気流れ方向下流側に延在する開状態からの、弁体５の先端部側の回動位置により吸気流動（スワール流及び／又はタンブル流）を制御する。尚、本実施形態は、スワール流及びタンブル流（斜めのスワール流）を生成すべく、全閉位置で、弁体５の先端部側に弁軸４の軸方向に偏った開口を形成するよう、先端部側の一部分に切欠き５ａを形成してある。 A storage space 3 when the intake flow control valve is opened is formed in the passage wall on the bottom side of the rectangular cross section of the intake passage 2, and the direction perpendicular to the intake flow direction is upstream of the storage space 3 in the intake flow direction. Further, the valve shaft 4 of the intake flow control valve is arranged. An intake flow control valve (valve element) is provided for each cylinder, but the valve shaft 4 is common and is rotated by a motor (not shown).
The intake flow control valve is formed by attaching a base end portion of a flat valve body 5 to the valve shaft 4 (a semicircular cross section where the valve body 5 is attached) with a screw 6 as a fastening means. The intake flow (swirl flow and / or tumble flow) is controlled by the rotational position of the front end portion side of the valve body 5 from the open state where the front end portion of the valve body 5 extends downstream in the intake flow direction with respect to the valve shaft 4. . In the present embodiment, in order to generate a swirl flow and a tumble flow (oblique swirl flow), an opening that is biased in the axial direction of the valve shaft 4 is formed on the distal end side of the valve body 5 in the fully closed position. A notch 5a is formed in a part on the tip side.

ここで、吸気通路壁に、弁体５の全閉位置で、弁体５の先端部と当接することにより、当接部をシールする弾性シール部材（ガスケット）９を設ける。弾性シール部材９としては、ゴム、シリコン等を使用する。
具体的には、吸気流動制御弁が配置される吸気マニホールド１の下流側端部に、吸気通路壁を構成するように、図３に示されるような別ピース７を挿入固定し、この別ピース７に、弁体５の先端側を逃げる切欠き８を形成し、この切欠き８に近接させて前記弾性シール部材９を取付けてある。別ピース７は、樹脂あるいはアルミ合金製の吸気マニホールド１に対し、樹脂あるいはアルミ合金などで作る。 Here, an elastic seal member (gasket) 9 is provided on the intake passage wall to seal the contact portion by contacting the tip of the valve body 5 at the fully closed position of the valve body 5. As the elastic seal member 9, rubber, silicon or the like is used.
Specifically, another piece 7 as shown in FIG. 3 is inserted and fixed at the downstream end of the intake manifold 1 where the intake flow control valve is arranged so as to form an intake passage wall. 7 is formed with a notch 8 that escapes the distal end side of the valve body 5, and the elastic seal member 9 is attached in close proximity to the notch 8. The separate piece 7 is made of resin or aluminum alloy with respect to the intake manifold 1 made of resin or aluminum alloy.

このような構成とすることにより、弁体５の全閉位置で、弁体５の先端部が弾性シール部材９に当接し、当接部をシールして、隙間を０にすることができる。よって、空気の逃げがなくなり、ガス流動を大幅に強化することができる。
特にエミッション要求が大きい冷機始動時に、大きなガス流動を作り出すことで、エミッション低減（ＨＣ低減）、燃費向上（ＥＧＲ率アップ→ポンプロス低減）、コスト削減（排気温度上昇による触媒量の低減）などを図ることができる。 With such a configuration, at the fully closed position of the valve body 5, the tip end portion of the valve body 5 abuts on the elastic seal member 9, and the abutment portion is sealed, so that the gap can be reduced to zero. Therefore, there is no air escape and the gas flow can be greatly enhanced.
By creating a large gas flow at the start of a cold machine that has a particularly high emission requirement, the emission reduction (HC reduction), fuel efficiency improvement (EGR rate increase → pump loss reduction), cost reduction (catalyst amount reduction due to exhaust temperature rise), etc. be able to.

また、本実施形態の吸気流動制御弁は、全開時には、吸気通路壁に格納されるため、弁軸が吸気通路中心を横断するものに対し、通気抵抗を少なくすることができ、出力向上を図ることができる。
また、本実施形態の吸気流動制御弁は、中間開度をとることが可能であり、最適なＥＧＲ率を得ることができ、これによって燃費向上を図ることができる。 In addition, since the intake flow control valve of the present embodiment is stored in the intake passage wall when fully opened, the ventilation resistance can be reduced and the output can be improved compared to the valve shaft that crosses the center of the intake passage. be able to.
Further, the intake flow control valve of the present embodiment can take an intermediate opening, and can obtain an optimum EGR rate, thereby improving fuel efficiency.

また、本実施形態のように、吸気流動制御弁が配置される吸気マニホールド１の下流側端部に、吸気通路壁を構成するように別ピース７を挿入固定し、この別ピース７に弾性シール部材９を保持させるようにすることで、簡単に実施できる。
次に弾性シール部材９の範囲について説明する。
上記実施形態では、図４（ａ）に示すような別ピース７及び弾性シール部材９として、弾性シール部材９を弁体５の先端部に対応させて、図４（ｂ）に示す弁体５のＳ１部分をシールしたが、図５（ａ）、（ｂ）に示すように、弁体５の切欠き５ａを除く部分にのみ、弾性シール部材９を設けるようにしてもよい。 Further, as in the present embodiment, another piece 7 is inserted and fixed at the downstream end of the intake manifold 1 where the intake flow control valve is arranged so as to form an intake passage wall, and an elastic seal is attached to the separate piece 7. By holding the member 9, it can be implemented easily.
Next, the range of the elastic seal member 9 will be described.
In the above embodiment, as the separate piece 7 and the elastic seal member 9 as shown in FIG. 4A, the elastic seal member 9 is made to correspond to the tip of the valve body 5, and the valve body 5 shown in FIG. However, as shown in FIGS. 5 (a) and 5 (b), the elastic seal member 9 may be provided only in the portion of the valve body 5 excluding the notch 5a.

また、図６（ａ）に示すようなコ字状（馬蹄形）の別ピース７及び弾性シール部材９として、弾性シール部材９を弁体５の先端部と両側部とに対応させて、図６（ｂ）に示す弁体５のＳ１、Ｓ２、Ｓ３部分をシールするようにしてもよい。この場合も、図７（ａ）、（ｂ）に示すように、弁体５の切欠き５ａを除く部分にのみ、弾性シール部材９を設けるようにしてもよい。   Moreover, as another U-shaped (horse-shoe-shaped) piece 7 and an elastic seal member 9 as shown in FIG. 6A, the elastic seal member 9 is made to correspond to the front end portion and both side portions of the valve body 5, and FIG. You may make it seal the S1, S2, S3 part of the valve body 5 shown to (b). Also in this case, as shown in FIGS. 7A and 7B, the elastic seal member 9 may be provided only in the portion of the valve body 5 excluding the notch 5a.

次に別ピース７への弾性シール部材９の取付けの態様について説明する。
別ピース７への弾性シール部材９の取付けは、別ピース７に予め形成した溝に挿入して接着したり、圧入してもよいし、図８に示すように、弾性シール部材９の側部に予め小突起９ａを形成しておくことで、圧入してもよい。尚、このような方法による場合、別ピース７を省略し、吸気マニホールド１の内壁に直接取付けることも可能である。 Next, an aspect of attaching the elastic seal member 9 to another piece 7 will be described.
The elastic seal member 9 can be attached to the separate piece 7 by being inserted into a groove formed in the separate piece 7 and bonded or press-fitted. As shown in FIG. Alternatively, the small protrusions 9a may be formed in advance so as to be press-fitted. In the case of such a method, the separate piece 7 can be omitted and directly attached to the inner wall of the intake manifold 1.

また、別ピース７への弾性シール部材９の取付けとして、図９に示すように、弾性シール部材９を断面Ｔ字状に形成し、別ピース７側の溝も同形状とすることで、弾性シール部材９の頭部を吸気マニホールド１と別ピース７との間に挟持でき、弾性シール部材９の脱落を防止できる。
更に、図１０に示すように、吸気マニホールド１側にも溝を設けることで、弾性シール部材９を確実に位置決めできると共に、別ピース７の位置固定に利用できる。 Further, as shown in FIG. 9, the elastic seal member 9 is attached to another piece 7, and the elastic seal member 9 is formed in a T-shaped cross section, and the groove on the other piece 7 side has the same shape. The head of the seal member 9 can be sandwiched between the intake manifold 1 and the separate piece 7, and the elastic seal member 9 can be prevented from falling off.
Furthermore, as shown in FIG. 10, by providing a groove also on the intake manifold 1 side, the elastic seal member 9 can be reliably positioned and used for fixing the position of the separate piece 7.

更に、図１１に示すように、図１０の構造とする場合に、弾性シール部材９の頭部に傾斜をつけることで、別ピース７の挿入が容易となる。
また、別ピース７への弾性シール部材９の取付けとして、図１２に示すように、ダウプリント（表面に凸を作り、強いシール力を持たせる技術）を用いてもよい。
また、図１３に示すように、別ピース全体を弾性シール部材１０として、弁体５の先端部に当接する突起１０ａを設けるようにしてもよい。 Furthermore, as shown in FIG. 11, when the structure of FIG. 10 is used, it is easy to insert another piece 7 by inclining the head of the elastic seal member 9.
Further, as shown in FIG. 12, as shown in FIG. 12, a dow print (a technique for forming a convex on the surface and giving a strong sealing force) may be used for attaching the elastic seal member 9 to the other piece 7.
As shown in FIG. 13, another whole piece may be used as the elastic seal member 10 to provide a protrusion 10 a that abuts on the tip of the valve body 5.

次に別ピース７の挿入固定の態様について説明する。
別ピース７の挿入固定方法としては、ねじ、カシメ（塑性変形）、溶着、圧入、突起によるセルフロック等が考えられる。
すなわち、吸気マニホールド１の下流側端部の開口端面に別ピース７を嵌合させて、挿入し、抜け止めのために、ねじで固定したり、挿入後にカシメ加工などにより塑性変形させて固定したり、スポット溶接により固定する。あるいは、挿入によりそのまま圧入固定する。 Next, an aspect of inserting and fixing the separate piece 7 will be described.
Possible methods for inserting and fixing the separate piece 7 include screws, caulking (plastic deformation), welding, press-fitting, self-locking by protrusions, and the like.
That is, another piece 7 is fitted to the opening end face of the downstream end portion of the intake manifold 1 and inserted, and is fixed with screws to prevent it from coming off, or is fixed by plastic deformation by caulking after insertion. Or fix by spot welding. Alternatively, it is press-fitted and fixed as it is by insertion.

突起によるセルフロックとしては、図１４に示すように、別ピース７に突起１１とバネ１２とを装備させておき、別ピース７をスライドさせて、突起１１を吸気マニホールド１側の係止孔１３に突入させることで、セルフロックする。
また、図１５に示すように、吸気マニホールド１及び別ピース７にそれぞれ高さの違いを持たせ、対応するツメ１４を係止孔１５に突入させて固定する。これは図１３の例の場合に適している。 As shown in FIG. 14, the self-locking by the protrusion is provided with the protrusion 11 and the spring 12 on another piece 7, and the other piece 7 is slid to engage the protrusion 11 with the locking hole 13 on the intake manifold 1 side. Self-locking by rushing into.
Further, as shown in FIG. 15, the intake manifold 1 and the separate piece 7 have different heights, and the corresponding claws 14 are inserted into the locking holes 15 and fixed. This is suitable for the example of FIG.

尚、以上の実施形態では、吸気流動制御弁が弁体５の先端部側に切欠き５ａを有している場合について説明したが、１気筒に２本の吸気ポートを有し、その一方を閉じることでスワール流を生成する場合は、閉止する吸気ポートに設ける吸気流動制御弁は、切欠きがなく、文字通り吸気通路を全閉にすればよいので、このような場合にも適用でき、また効果が大きいことは言うまでもない。   In the above embodiment, the case where the intake flow control valve has the notch 5a on the distal end side of the valve body 5 has been described. However, one cylinder has two intake ports, one of which is When generating a swirl flow by closing, the intake flow control valve provided at the intake port to be closed has no notch, and it is only necessary to fully close the intake passage. Needless to say, the effect is great.
