本考案は、多シリンダエンジンの吸、排気装置
の一部に使用されるマニフオールドに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manifold used as part of an intake and exhaust system for a multi-cylinder engine.
吸・排気の慣性効果を利用して多シリンダエン
ジンの吸入効率又は排気効率を向上させるため
に、エンジンのシリンダを吸入行程が重なり合わ

路における分吸通路側の端部に仕切を設けてこの
部分の集合通路をシリンダ群ごとに独立させるこ
とがある。 In order to improve the suction efficiency or exhaust efficiency of a multi-cylinder engine by utilizing the inertia effect of suction and exhaust, the cylinders of the engine are divided into two cylinder groups, with only cylinders whose suction strokes do not overlap as one group, In some cases, a partition is provided at the end of the collective passage of the intake and exhaust manifolds on the side of the partial suction passage to make this part of the collective passage independent for each cylinder group.
ところが、排気ブレーキ装置を備えた多シリン

ｂを設けていたので、仕切を設けることによる
吸・排気の慣性効果が半減してしまうという不都
合があつた。尚、図中、ｃは多シリンダエンジ
ン、ｄはマニフオールドである。 However, when it is necessary to install a butterfly valve such as a noise suppressor or exhaust valve in the collective passage, such as in a multi-cylinder engine equipped with an exhaust brake device, it is necessary to mount the engine as shown in Figures 1 to 3. The position of butterfly valve a was determined by considering the space and the effect of closing the valve, and partition b was provided only on the engine side from valve a, so the inertia effect of intake and exhaust caused by providing the partition was halved. I had the inconvenience of having to put it away. In the figure, c is a multi-cylinder engine, and d is a manifold.
本考案は、このような実状に鑑みてなされたも
のであつて、分岐通路の近傍において集合通路を
シリンダ群に対応して隔成する仕切を設けるとと
もに、前記集合通路の断面形状と略同一形状の孔

合通路を開閉するバタフライバルブを前記孔に開
閉回動自在に嵌合保持させることにより、常時は
このバタフライバルブを仕切の一部として機能さ
せるようにしたことを特徴としている。 The present invention has been developed in view of the above-mentioned circumstances, and includes providing a partition near the branch passage that separates the collecting passage corresponding to the cylinder groups, and a partition having substantially the same cross-sectional shape as the collecting passage. A hole is provided in the middle of the partition. A butterfly valve for opening and closing the collective passage is fitted and held in the hole so as to be rotatable in opening and closing, so that the butterfly valve normally functions as a part of the partition.
従つて、バタフライバルブが開いているとき
は、このバルブが仕切に設けられている孔に格納
されてこの仕切の一部として機能するが、バタフ
ライバルブを閉鎖回動すればこのバタフライバル
ブによつて集合通路が閉鎖される。 Therefore, when the butterfly valve is open, it is stored in the hole provided in the partition and functions as a part of this partition, but when the butterfly valve is rotated to close, the butterfly valve The gathering passage will be closed.
このために、エンジンの搭載性及び機能的な制
約を受けるバタフライバルブの位置に関係なく仕
切を必要な位置まで延設して吸・排気の慣性効果
を最大限に発揮させることができる。 Therefore, regardless of the position of the butterfly valve, which is subject to engine mountability and functional restrictions, the partition can be extended to the required position to maximize the inertial effect of intake and exhaust.
以下に本考案の実施例を第４図及び第５図に基

る。 Intake manifold 2 of multi-cylinder engine 1
forms branch passages 3, 3, . . . that are individually connected to the intake ports (not shown) of each cylinder, and a collective passage 4 that is commonly connected to all the branch passages 3, 3, . By providing a partition 5 at the downstream end of the collecting passage 4 and dividing it into two, the suction strokes of the cylinders shared by the individual collecting passages separated by the partition 5 do not overlap. That's what I do. That is, in the embodiment, the ignition order is 1-4-2-6-3-5 as a multi-cylinder engine.
Since this model uses an in-line 6-cylinder diesel engine, the first group of cylinders (1st, 2nd, and 3rd cylinders) are assigned to one collecting passage, and the 4th, 5th, and 6th cylinders are assigned to the other collecting passage. The partition 5 is provided so that the second cylinder group can be shared.

一部を構成するようにしている。 A hole 6 having approximately the same diameter as the inner diameter of the collective passageway 4 is provided in the middle of the partition 5, and a butterfly valve 7, which is opened and stored in the same plane as the partition 5, is fitted into the hole 6 so as to be rotatable in opening and closing. By holding them together, the valve 7 forms a part of the partition 5 when the valve 7 is opened.

る。 In other words, in the past, the partition and butterfly valve were completely independent, and the partition was provided only on the engine side of the valve, so from the viewpoint of engine mountability and performance improvement when the valve is closed, the valve was placed in the engine (branch passage). If the valve was installed close to the valve, the length of the partition would be shortened, making it impossible to obtain a sufficient inertia effect for intake and exhaust.However, in this invention, a butterfly valve forms part of the partition. Therefore, partitions can be provided on both sides of this valve. Furthermore, since the partitions on both sides are substantially continuous through the valve, even if the valve is placed close enough to the engine, the collective passage is independent for each cylinder group until it reaches the far part beyond the valve.・The inertia effect of the exhaust can be sufficiently increased.
尚、バタフライバルブの閉弁時は、このバルブ
の部分で仕切が途切れるが、この場合は吸・排気

であるので不都合はない。 Note that when the butterfly valve is closed, the partition is interrupted at this valve part, but this is not a problem since the exhaust brake is activated, which does not require the inertial effect of intake and exhaust.

等を回避することができる。 As explained above, according to the present invention, a hole having substantially the same shape as the collecting passage is provided in the partition, and a butterfly valve for opening and closing the collecting passage is fitted and held in the hole so as to be rotatable to open and close. Therefore, during normal operation when the collective passage is not closed, the butterfly valve can be retracted and retained in the hole to function as part of the partition, while allowing the butterfly valve to close accurately when the exhaust brake is activated, for example. Therefore, the actual length of the partition can be freely set regardless of the position of the valve. For this,
The butterfly valve is moved closer to the engine (branch passage) to improve the blocking effect and ease of mounting the engine, and the inertia effect of intake and exhaust obtained by providing a partition is sufficiently increased to provide an exhaust brake, etc. It can improve the intake and exhaust efficiency of multi-cylinder engines. In addition, since the butterfly valve is installed in the middle of the partition, even if the manifold is an exhaust manifold, the thermal load on the valve does not become extremely high, and it is possible to avoid problems such as sticking of the valve support part. .
