Description

本発明は、自動車等の車両の排気管乃至マフラーの排気口に装着して使用される車両排気管用燃費向上装置に関する。   The present invention relates to a fuel efficiency improving device for a vehicle exhaust pipe that is used by being mounted on an exhaust pipe of a vehicle such as an automobile or an exhaust port of a muffler.

従来、自動車の排気管に装着して所定の機能を発揮する装置として、例えば、特許文献1に記載の技術がある。   2. Description of the Related Art Conventionally, as a device that exhibits a predetermined function when mounted on an exhaust pipe of an automobile, for example, there is a technique described in Patent Document 1.

特許文献1には、エキゾーストパイプの排気口が記載されている。このエキゾーストパイプの排気口は、高速走行時において、車の後方に発生する乱気流が、排気ガスの放出に影響しないようにするためのものである。   Patent Document 1 describes an exhaust port of an exhaust pipe. The exhaust port of the exhaust pipe is for preventing turbulence generated behind the vehicle from affecting the emission of exhaust gas when traveling at high speed.

詳細には、特許文献1に記載のエキゾーストパイプの排気口は、エキゾーストパイプの排気口際にステーで支持することにより外筒を取り付けてその部分を二重筒構造としている。また、同排気口は、エキゾーストパイプの下手開口を拡開部とすると共に、外筒の下手開口を拡開部とし、外筒の後端開口面をエキゾーストパイプの後端開口面に一致させている一方、エキゾーストパイプの上手側をマフラの断面より大きく拡開した流入口としている。また、エキゾーストパイプと外筒との間には、途中に絞りを有する空気流路を形成している。これにより、エキゾーストパイプ上手側の流入口より流入した外気がこの空気流路を通過し、エキゾーストパイプから排出される排気ガスの周囲にバリヤを作るようエキゾーストパイプ下手側の拡開部から放出される。このように、この排気口では、高速走行時、空気流入手段から導入した走行風を円錐台筒状に放出することにより、その放出した外気の層がバリヤとなって排気ガスが乱気流の影響を受けることなく排出されるため、エンジン出力の低下や、燃料消費量の増大といったエンジン性能への影響はなくなるとされている。   Specifically, the exhaust pipe exhaust port described in Patent Document 1 is supported by a stay at the exhaust pipe exhaust port end so that an outer cylinder is attached to form a double cylinder structure. In addition, the exhaust port has the lower opening of the exhaust pipe as an expanded portion, the lower opening of the outer tube as an expanded portion, and the rear end opening surface of the outer cylinder matches the rear end opening surface of the exhaust pipe. On the other hand, the upper side of the exhaust pipe is an inlet that is larger than the cross section of the muffler. Further, an air flow path having a throttle in the middle is formed between the exhaust pipe and the outer cylinder. As a result, the outside air flowing in from the inlet on the upper side of the exhaust pipe passes through this air flow path and is discharged from the expanded portion on the lower side of the exhaust pipe so as to create a barrier around the exhaust gas discharged from the exhaust pipe. . In this way, at this exhaust port, when traveling at high speed, the traveling wind introduced from the air inflow means is discharged into a truncated cone shape, so that the released outside air layer becomes a barrier and the exhaust gas is affected by turbulence. Since it is discharged without receiving it, it is said that there is no influence on engine performance such as a decrease in engine output and an increase in fuel consumption.

特開平08−093469号公報Japanese Patent Laid-Open No. 08-093469

ここで、特許文献1に記載の技術は、エキゾーストパイプの排気口際に外筒を装着してエキゾーストパイプと外筒との間の空気流を形成する構成において、外筒とエキゾーストパイプの下手側を共に拡開部とし、かつ、その後端開口面と外筒の後端開口面を一致させるよう装着することが、上記エンジン出力低下や燃料消費量増大への影響をなくすという発明の課題を達成するための必須の構成とされている(同文献の請求項1、段落0006及び0008)。   Here, the technique described in Patent Document 1 is a configuration in which an outer cylinder is attached to the exhaust pipe at the exhaust port to form an air flow between the exhaust pipe and the outer cylinder, and the lower side of the outer cylinder and the exhaust pipe. To achieve both the above-mentioned widened portion and the rear end opening surface and the rear end opening surface of the outer cylinder coincide with each other to eliminate the influence on the engine output reduction and the fuel consumption increase. This is an indispensable configuration for this purpose (claim 1, paragraphs 0006 and 0008 of the same document).

しかし、外筒は着脱自在の構造として後付け可能とすることもできるとされ(段落0011)、その製造時に下手側に予め拡開部を形成することは容易であるものの、外筒を装着する既存のエキゾーストパイプの排気口部分が拡開部を有しないタイプ(ストレートタイプ)である場合、そのストレート(直線管)部分を外筒の拡開部に合わせて拡開するという後工程の現場作業が必要となる。即ち、特許文献1に記載の発明は、既存のエキゾーストパイプを構成要件としているものの、後付けされる部材としては外筒(及びその取付部分としてのステー等)であるため、その課題を達成するためには、既存の自動車部品であるエキゾーストパイプの後加工が必要となる。しかし、一般に、自動車部品の後加工は面倒であり、また、違法改造として法令違反となる可能性も否定できない。したがって、特許文献1に記載の発明は、既存のエキゾーストパイプのいずれにでも簡単に適用できるものではない。   However, it is said that the outer cylinder can be retrofitted as a detachable structure (paragraph 0011). Although it is easy to form an expanded portion in advance on the lower side at the time of manufacturing, the existing cylinder to which the outer cylinder is attached If the exhaust pipe of the exhaust pipe is of a type that does not have an expanded portion (straight type), a post-site work is required to expand the straight (straight tube) portion to match the expanded portion of the outer cylinder. It becomes. That is, although the invention described in Patent Document 1 uses an existing exhaust pipe as a constituent element, the member to be retrofitted is an outer cylinder (and a stay or the like as a mounting portion thereof), and therefore, the object is achieved. Requires post-processing of an exhaust pipe, which is an existing automobile part. However, in general, the post-processing of automobile parts is troublesome, and the possibility of illegal modification is a violation of laws and regulations. Therefore, the invention described in Patent Document 1 is not easily applicable to any existing exhaust pipe.

そこで、本発明は、あらゆるタイプの既存のエキゾーストパイプ乃至排気管に対して容易に着脱自在に装着することができ、かつ、排気管の外側の外気を導入する空気流路を排気管との間に形成して、同流路に流入する外気により自動車等の車両の排気管からの排気効率を向上することにより、燃料消費量を低減することができる車両排気管用燃費向上装置の提供を課題とする。   Therefore, the present invention can be easily detachably attached to all types of existing exhaust pipes or exhaust pipes, and an air passage for introducing outside air outside the exhaust pipe is provided between the exhaust pipe and the exhaust pipe. It is an object of the present invention to provide a vehicle exhaust pipe fuel efficiency improvement device that can reduce fuel consumption by improving the exhaust efficiency from the exhaust pipe of a vehicle such as an automobile by the outside air flowing into the flow path To do.

Embodiment 1
The vehicle exhaust pipe fuel consumption improvement apparatus according to Embodiment 1 of the present invention is used by being mounted on an exhaust port of an exhaust pipe (muffler) of a vehicle such as an automobile. Specifically, as shown in FIGS. 1 and 5, the vehicle exhaust pipe fuel efficiency improvement device includes a mounting portion 10 and an outer cylinder portion 20. The mounting portion 10 is detachably mounted on an exhaust port portion of an exhaust pipe of a vehicle, has a cylindrical shape as a whole, and has a circular proximal end opening 11 and a circular distal end opening 12. Further, the mounting portion 10 has a cutout portion 13 by cutting a part in the circumferential direction linearly along the axial center, thereby providing flexibility or elastic stretchability in the radial direction. Has been granted. On the other hand, the outer cylinder portion 20 is fixedly disposed outside the exhaust port portion of the exhaust pipe via the mounting portion 10, and has an upstream side enlarged portion 21, a downstream side enlarged portion 22, and a reduced diameter. It is integrally formed in a deformed cylindrical shape or a venturi shape comprising a portion 23 (both ends in the axial direction are horn-shaped). The outer cylinder part 20 has a larger diameter than the mounting part 10 as a whole (both parts). In detail, the upstream side enlarged diameter portion 21 has a predetermined length portion on one end side in the axial direction of the outer cylinder portion 20 (a base end side on the upstream side) in a horn shape toward the base end on the upstream side. The diameter is increased and the base end (upstream base end surface) is opened. Further, the downstream-side enlarged diameter portion 22 enlarges a predetermined length portion on the other end side in the axial direction of the outer cylinder portion 20 (the tip side on the downstream side) in a horn shape toward the tip on the downstream side. Thus, the tip (downstream tip surface) is open. Further, the reduced diameter portion 23 is formed to have the smallest diameter between the upstream enlarged portion 21 and the downstream enlarged portion 22 (the minimum diameter portion and the downstream enlarged diameter of the upstream enlarged portion 21). It connects with the smallest diameter part of the part 22), and makes a substantially short cylindrical shape. Here, the circular opening of the end surface of the upstream side enlarged diameter portion 21 (the base end surface of the outer cylinder portion 20) constitutes the outside air inlet 24 (which becomes the maximum diameter portion of the upstream side enlarged diameter portion 21), and the downstream side The circular opening on the end surface of the enlarged diameter portion 22 (the front end surface of the outer cylinder portion 20) constitutes an induction exhaust port 25 (which becomes the maximum diameter portion of the downstream enlarged diameter portion 22). Moreover, it is preferable that the outside air introduction port 24 has a diameter larger than that of the induction exhaust port 25 so that a sufficient amount of outside air can be introduced during use, which will be described later. The downstream enlarged portion 22 has an axial length larger than that of the upstream enlarged portion 21, preferably about 2 to 10 times, more preferably about 3 to 5 times the upstream enlarged portion 21.

In the state, it is integrally connected and fixed to the outside of the mounting portion 10 so as to be coaxial with the mounting portion 10. Specifically, the end surface position of the front end of the mounting portion 10 (the position of the front end opening 12) is preferably within the range of the reduced diameter portion 23 of the outer cylinder portion 20, preferably the reduced diameter portion 20 (which has the smallest diameter). A pair of connecting pieces 31 connects the mounting part 10 and the outer cylinder part 20 so as to be in the axial center position. Specifically, a pair of flat plate-like connecting pieces 31 are attached to the mounting portion 10 and the outer cylinder at two angular positions that are separated from the notch 13 of the mounting portion 10 by about 90 degrees in the clockwise direction and the counterclockwise direction, respectively. It extends between the parts 20 so as to extend in the radial direction. The connecting piece 31 may be provided over the entire length of the insertion portion of the mounting portion 10, or only a part of the length may be provided, or at intervals in the length direction of the insertion portion of the mounting portion 10. A plurality (divided) connecting pieces may be provided. As a result, the space between the outer peripheral surface of the mounting portion 10 and the inner peripheral surface of the opposing portion of the outer cylinder portion 20 (mainly the upstream side enlarged diameter portion 21) is reduced from the outside air inlet 24 of the upstream side enlarged diameter portion 21. An air passage (air passage) that gradually decreases in diameter toward the diameter portion 23 is formed. Further, in the internal space of the outer cylindrical portion 20, a space where the mounting portion 10 does not exist (by the inner peripheral surface of the downstream-side enlarged diameter portion 22) is formed on the downstream side of the tip of the mounting portion 10. And, between the tip opening 12 which is the tip of the mounting part 10 and the reduced diameter part 23 of the outer cylinder part 20, in the internal space of the outer cylinder part 20 (especially, the upstream side enlarged diameter part 21 and the mounting part). A ring-shaped narrow space NP that is the smallest space is formed in the space between the two spaces.

上記のように構成した実施の形態1の車両排気管用燃費向上装置の使用方法及び動作について説明する。
図6に示すように、車両排気管用燃費向上装置は、車両の排気管(典型的には、自動車のマフラー)1の排気口2に装着部10を着脱自在に装着して固定される。即ち、車両排気管用燃費向上装置では、装着部10が排気管1の排気口2部分の外周面に密嵌される円筒状をなし、その下流側の先端開口(軸方向における下流側の端面12aの位置)を外筒部20の縮径部23に配置した状態で、外筒部20の(主に上流側拡径部21の)内部に一体的に固定されている。そして、例えば、装着部10の通常の内径(外力を加えないときの内径)を取付対象の排気管1の外径より若干小さく設定し、切欠部13を若干開いて装着部10を若干拡径した状態で排気管1の排気口2の先端から外嵌する。すると、装着部10は、自らの弾性復帰力によって切欠部13を通常の幅に閉じると共に半径方向に押圧され、排気口2部分に密嵌固定される。なお、このとき、例えば、装着部10の基端部の外周面に金属製等の円環帯状の締結部材乃至締付具(ステンレスバンドやステンレスクランプ等)を着脱自在に装着したり、装着部10の切欠部13部分の一対の端縁から放射方向に延びるよう板状の突部を一体形成してその突部をネジ止めしたりすることにより、フランジ状の締結部材の締結力乃至締め付け力により装着部10を排気管1に対してより強固に取り付けても良い。このとき、排気管1の排気口2の端面2aの位置を外筒部20の縮径部23の範囲内に配置するよう、装着部10を介して外筒部20を排気管1の排気口2部分に装着するが、本実施の形態では、装着部10の先端位置(先端開口12の端面12aの位置)が外筒部20の縮径部23の範囲内(好ましくはその中央の最小径位置)に位置するよう、挿着部10に対して外筒部20が固定されているため、排気管1の排気口2の端面2aを装着部10の端面12aと合致させるだけで、自動的に、排気管1の排気口2の端面2aの位置を外筒部20の縮径部23の範囲内に配置することができる。
The usage method and operation of the vehicle exhaust pipe fuel efficiency improving apparatus of the first embodiment configured as described above will be described.
As shown in FIG. 6, the fuel efficiency improving device for a vehicle exhaust pipe is fixed by detachably mounting a mounting portion 10 on an exhaust port 2 of a vehicle exhaust pipe (typically, an automobile muffler) 1. That is, in the vehicle exhaust pipe fuel efficiency improvement device, the mounting portion 10 has a cylindrical shape that is tightly fitted to the outer peripheral surface of the exhaust port 2 portion of the exhaust pipe 1, and has a downstream end opening (a downstream end face 12a in the axial direction). Is located in the reduced diameter portion 23 of the outer cylinder portion 20 and is integrally fixed to the inside of the outer cylinder portion 20 (mainly in the upstream diameter expansion portion 21). For example, the normal inner diameter (the inner diameter when no external force is applied) of the mounting portion 10 is set slightly smaller than the outer diameter of the exhaust pipe 1 to be attached, the notch 13 is slightly opened, and the mounting portion 10 is slightly enlarged. In this state, the exhaust pipe 1 is fitted from the tip of the exhaust port 2. Then, the mounting portion 10 closes the notch 13 to a normal width by its own elastic restoring force and is pressed in the radial direction, and is fitted and fixed to the exhaust port 2 portion. At this time, for example, an annular belt-like fastening member or a fastener (such as a stainless steel band or a stainless steel clamp) made of metal or the like is detachably mounted on the outer peripheral surface of the base end portion of the mounting portion 10, or the mounting portion A plate-like protrusion is integrally formed so as to extend in a radial direction from a pair of edges of the notch 13 portion, and the protrusion is screwed to fix the fastening force or tightening force of the flange-like fastening member. Thus, the mounting portion 10 may be more firmly attached to the exhaust pipe 1. At this time, the outer cylinder part 20 is connected to the exhaust port of the exhaust pipe 1 via the mounting part 10 so that the position of the end surface 2a of the exhaust port 2 of the exhaust pipe 1 is located within the range of the reduced diameter part 23 of the outer cylinder part 20. In this embodiment, the distal end position of the mounting portion 10 (the position of the end surface 12a of the distal end opening 12) is within the range of the reduced diameter portion 23 of the outer cylinder portion 20 (preferably the minimum diameter at the center). Since the outer cylinder portion 20 is fixed to the insertion portion 10 so as to be positioned at the position), the end surface 2a of the exhaust port 2 of the exhaust pipe 1 can be automatically matched with the end surface 12a of the mounting portion 10. In addition, the position of the end surface 2 a of the exhaust port 2 of the exhaust pipe 1 can be disposed within the range of the reduced diameter portion 23 of the outer cylinder portion 20.

これにより、排気管1の排気口2部分の外周面と外筒部20の上流側拡径部21の内周面との間に、外筒部20の上流側拡径部21の外気導入口24から縮径部23に向かって徐々に縮径する変形リング状の第1の空気流路が形成される。また、排気管1の排気口2の端面2aより下流側には、外筒部20の縮径部23から下流側拡径部22の誘引排気口25に向かって徐々に拡径する円錐台状の第2の空気流路が形成され、その大部分(中央部分)が排気管1の排気口2に対向する。一方、排気管1の排気口2の端面2a部分と縮径部23との間には、最小径となるリング状の前記狭小空間NPが、前記第1の空気流路と第2の空気流路(特に、その外周部分)とを連通するよう形成される。したがって、この装着状態では、図6中の白抜き矢印で示すように、車両の走行に伴って、車両の排気管1の周囲の外気が、外筒部20の上流側拡径部21の外気導入口24から内部の第1の空気流路に案内及び導入され、前記狭小路NPを経て、第2の空気流路へと流動する。このとき、まず、外気導入口24から縮径部23に至る第1の空気流路では、その径が徐々に縮小するため、導入された外気の流速が徐々に増加し(ベンチュリー効果)、狭小路NPで最高流速となって、縮径部23から誘引排気口25に至る第2の空気流路に放出される。このため、最高流速の外気が、狭小路NPの直下乃至直後(下流側)に位置する排気管1の排気口2の端面2aから下流側拡径部22の内周面に沿って軸方向に流動し、排気管1の排気口2の端面2aの直下乃至直後の第2の空気流路の気圧が最大負圧となる(ベルヌーイの定理)。これにより、排気管1の排気口2から排出される排気ガスは、負圧となった第2の空気流路内に強制的に誘引され、通常の排出速度よりも高い速度で第2の空気流路内を流動して、誘引排気口25から排出される。その結果、排気管1からの排気効率を格段に向上することができ、燃料消費量を低減して燃費を向上することができる。また、装着部10は、自動車等の排気管1の排気口2部分の外周面の形状に合わせるよう撓ませて自らの弾性により、或いは、締付具等により排気管1に圧接されて着脱自在に装着されるため、従来技術(特許文献1の技術)のように専用のエキゾーストパイプを新たに製作する必要はなく、いかなる型の車両の排気管1であっても既存の排気管1に着脱自在に装着して使用することができる。   As a result, the outside air introduction port of the upstream side enlarged diameter portion 21 of the outer cylinder portion 20 is disposed between the outer circumferential surface of the exhaust port 2 portion of the exhaust pipe 1 and the inner circumference surface of the upstream side enlarged diameter portion 21 of the outer cylinder portion 20. A deformed ring-shaped first air flow path that gradually decreases in diameter from 24 toward the reduced diameter portion 23 is formed. Further, on the downstream side of the end surface 2 a of the exhaust port 2 of the exhaust pipe 1, a truncated cone shape that gradually increases in diameter from the reduced diameter portion 23 of the outer cylindrical portion 20 toward the induced exhaust port 25 of the downstream enlarged portion 22. The second air flow path is formed, and the most part (central part) faces the exhaust port 2 of the exhaust pipe 1. On the other hand, between the end surface 2a portion of the exhaust port 2 of the exhaust pipe 1 and the reduced diameter portion 23, the ring-shaped narrow space NP having a minimum diameter is formed between the first air flow path and the second air flow. It forms so that a path | route (especially the outer peripheral part) may be connected. Therefore, in this mounted state, as indicated by the white arrow in FIG. 6, as the vehicle travels, the outside air around the exhaust pipe 1 of the vehicle becomes the outside air of the upstream side enlarged diameter portion 21 of the outer cylinder portion 20. It is guided and introduced from the introduction port 24 to the internal first air flow path, and flows to the second air flow path through the narrow path NP. At this time, first, in the first air flow path from the outside air introduction port 24 to the reduced diameter portion 23, the diameter is gradually reduced, so that the flow rate of the introduced outside air gradually increases (Venturi effect) and becomes narrow. A maximum flow velocity is obtained in the path NP, and the air is discharged to the second air flow path from the reduced diameter portion 23 to the induction exhaust port 25. For this reason, the outside air having the highest flow velocity is axially extended from the end surface 2a of the exhaust port 2 of the exhaust pipe 1 located immediately below or immediately after (on the downstream side) the narrow path NP along the inner peripheral surface of the downstream enlarged portion 22. The air pressure of the second air flow path immediately below and immediately after the end face 2a of the exhaust port 2 of the exhaust pipe 1 becomes the maximum negative pressure (Bernoulli's theorem). As a result, the exhaust gas discharged from the exhaust port 2 of the exhaust pipe 1 is forcibly attracted into the second air flow path having a negative pressure, and the second air is at a speed higher than the normal discharge speed. It flows in the flow path and is discharged from the attraction exhaust port 25. As a result, the exhaust efficiency from the exhaust pipe 1 can be remarkably improved, the fuel consumption can be reduced, and the fuel consumption can be improved. In addition, the mounting portion 10 is detachable by being bent so as to conform to the shape of the outer peripheral surface of the exhaust port 2 portion of the exhaust pipe 1 of an automobile or the like, by its own elasticity, or by being pressed against the exhaust pipe 1 by a fastener or the like. Therefore, it is not necessary to newly manufacture a special exhaust pipe as in the prior art (the technology of Patent Document 1), and any type of vehicle exhaust pipe 1 can be attached to and detached from the existing exhaust pipe 1. It can be used freely.

実施の形態2
本発明の実施の形態2に係る車両排気管用燃費向上装置は、図7、図10、図11に示すように、実施の形態1の車両排気管用燃費向上装置の外筒部20の内部において縮径部23より下流側の位置に、整流部40を一体的に固定したものである。その他の構成は、基本的に、実施の形態1の車両排気管用燃費向上装置と同様である。詳細には、整流部40は、装着部10より小径の円筒状をなし、装着部10の下流側の先端に対向するよう、かつ、装着部10と同軸上となるよう、外筒部20の下流側拡径部22内に配置固定される。また、整流部40は、上流側の基端開口を導入口41とすると共に、下流側の先端開口を導出口42としている。更に、整流部40は、その上流側の基端の導入口41を装着部の下流側の先端に近接して対向配置すると共に、その下流側の先端の導出口を外筒部20の下流側拡径部22の先端の誘引排気口25より所定距離突出して配置している。また、整流部40は、下流側拡径部22の誘引排気口25より突出して配置される先端部(突出部)を、外筒部20の下流側拡径部22の拡径状態に対応して先端に向かって拡径する拡径部43とし、当該拡径部43の先端開口を前記導出口42としている。一方、整流部40は、図8及び図9に示すように、拡径部43を除く主要部分である同一径部分乃至純粋円筒部分(全長の4/5〜9/10程度の部分)を誘引排気口25から内部に挿入し、その基端の導入口41が微小間隔dを隔てて装着部10の先端開口12と対向するよう、かつ、装着部10と同軸上となるよう、下流側拡径部22の内側に一体的に連結固定されている。具体的には、前記連結片31と90度隔てた位置に、一対の平板状の連結片32が、整流部40と外筒部20との間をそれらの放射方向に延びて掛け渡している。前記微小間隔dは、装着対象の排気管1の種類や径にもよるが、通常、約1mm〜3mmの範囲内、好ましくは、約1mm〜2mmの範囲内とする。なお、連結片32は、連結片31と同様、整流部40の挿入部分の全長にわたって設けても良く、その一部の長さのみ設けても良く、或いは、整流部40の挿入部分の長さ方向に間隔を置いて複数(分割した)連結片を設けても良い。これにより、整流部40の外周面と外筒部20の対向部分(下流側拡径部22)の内周面との間には、下流側拡径部22の基端から先端の誘引排気口25に向かって徐々に拡径する空気通路(空気流路)が形成される。また、整流部40の内部には、装着部10よりも小径の円柱状の空間が形成されている。
Embodiment 2
As shown in FIGS. 7, 10, and 11, the vehicle exhaust pipe fuel consumption improvement apparatus according to Embodiment 2 of the present invention is contracted inside the outer cylinder portion 20 of the vehicle exhaust pipe fuel consumption improvement apparatus. The rectifying unit 40 is integrally fixed at a position downstream of the diameter portion 23. The other configuration is basically the same as that of the vehicle exhaust pipe fuel consumption improvement apparatus of the first embodiment. Specifically, the rectifying unit 40 has a cylindrical shape with a smaller diameter than the mounting unit 10, faces the downstream end of the mounting unit 10, and is coaxial with the mounting unit 10. Arranged and fixed in the downstream enlarged diameter portion 22. Further, the rectifying unit 40 has an upstream base end opening as an inlet 41 and a downstream tip opening as an outlet 42. Further, the rectifying unit 40 is arranged so that the upstream-side proximal end introduction port 41 is opposed to the downstream end of the mounting unit so as to face the downstream side, and the downstream-side distal end outlet is provided on the downstream side of the outer cylinder part 20. The diameter-expanded portion 22 is disposed so as to protrude a predetermined distance from the induction exhaust port 25 at the tip. Further, the rectifying unit 40 corresponds to the diameter-enlarged state of the downstream-side enlarged portion 22 of the outer cylinder portion 20 with the distal end portion (projecting portion) arranged to project from the induction exhaust port 25 of the downstream-side enlarged portion 22. Thus, the diameter-expanded portion 43 is increased in diameter toward the tip, and the leading end opening of the diameter-expanded portion 43 is used as the outlet port 42. On the other hand, as shown in FIG. 8 and FIG. 9, the rectifying unit 40 attracts the same diameter part or pure cylinder part (a part of about 4/5 to 9/10 of the total length) which is a main part excluding the enlarged diameter part 43. It is inserted into the interior from the exhaust port 25, and the downstream side expansion is performed so that the introduction port 41 at the base end thereof is opposed to the distal end opening 12 of the mounting unit 10 with a small interval d and is coaxial with the mounting unit 10. It is connected and fixed integrally inside the diameter portion 22. Specifically, a pair of flat plate-like connecting pieces 32 extend between the rectifying unit 40 and the outer cylinder 20 in the radial direction at a position 90 degrees apart from the connecting piece 31. . Although the minute distance d depends on the type and diameter of the exhaust pipe 1 to be mounted, it is usually in the range of about 1 mm to 3 mm, preferably in the range of about 1 mm to 2 mm. The connecting piece 32 may be provided over the entire length of the insertion portion of the rectifying unit 40, as in the case of the connecting piece 31, or only a part of the length of the insertion portion of the rectifying unit 40. A plurality of (divided) connecting pieces may be provided at intervals in the direction. Thereby, the induction exhaust port of the front-end | tip from the proximal end of the downstream enlarged part 22 to the front end between the outer peripheral surface of the rectification | straightening part 40 and the internal peripheral surface of the opposing part (downstream enlarged part 22) of the outer cylinder part 20 is carried out. An air passage (air passage) that gradually increases in diameter toward 25 is formed. In addition, a cylindrical space having a smaller diameter than the mounting portion 10 is formed inside the rectifying unit 40.

上記のように構成した実施の形態2の車両排気管用燃費向上装置は、図12に示すように、実施の形態1の車両排気管用燃費向上装置と同様にして、排気管1の排気口2に装着され、同様の作用効果を発揮する。特に、実施の形態2の車両排気管用燃費向上装置は、排気管1への装着時に、(装着部10に対向する)整流部40が排気管1の排気口2に微小隙間dを置いて対向して配置される。したがって、図12中の白抜き矢印で示すように、車両の走行に伴って、車両の排気管1の周囲の外気が、外筒部20の上流側拡径部21の外気導入口24から内部の第1の空気流路に案内及び導入され、狭小路NPを経て第2の空気流路へと流動し、狭小路NPで最高流速となって、縮径部23から誘引排気口25に至る第2の空気流路に放出される。このとき、排気管1の排気口2から排出される排気ガスは、特にその外周部分の排気ガスが、負圧となった第2の空気流路内に強制的に誘引され、通常の排出速度よりも高い速度で第2の空気流路内を流動して、誘引排気口25から排出される。また、排気口2の軸心部分から排出される排気ガスは、整流部40内に進入して流動するが、やはり、このとき、装着部10と整流部40との間の微小隙間dの間隙を介して、第2の空気流路の負圧によって軸方向の下流側に誘引され、通常の排出速度よりも高い速度で整流部40内を流動して、導出口42から排出される。同時に、整流部40の内部空間は、拡径部43によるベンチュリー効果によりその先端部分が負圧となるため、整流部40内の排気ガスは、先端の拡径部43内の負圧部分でもある程度誘引されて、より高い速度で導出口42から排出される。更に、このとき、排気ガスは、排気管1と同軸状となった整流部40によって整流され、排気効率を一層向上した状態で導出口42から排出される。その結果、実施の形態2の車両排気管用燃費向上装置は、排気管1からの排気効率を一層向上することができ、燃料消費量を更に低減して燃費をより向上することができる。なお、整流部40の先端部の拡径部43は省略したり、整流部40の先端部を他の部分と同一径として単純円筒状としたりしても良く、この場合でも、発明の作用効果を大きく損なうことはない。   The vehicle exhaust pipe fuel consumption improvement apparatus of the second embodiment configured as described above is provided at the exhaust port 2 of the exhaust pipe 1 in the same manner as the vehicle exhaust pipe fuel consumption improvement apparatus of the first embodiment, as shown in FIG. It is installed and exhibits the same effects. In particular, in the fuel efficiency improving device for a vehicle exhaust pipe according to the second embodiment, when the exhaust pipe 1 is mounted, the rectifying section 40 (opposite the mounting section 10) faces the exhaust port 2 of the exhaust pipe 1 with a minute gap d. Arranged. Therefore, as shown by the white arrow in FIG. 12, as the vehicle travels, the outside air around the exhaust pipe 1 of the vehicle is transferred from the outside air inlet 24 of the upstream side enlarged diameter portion 21 of the outer cylinder portion 20 to the inside. Is guided and introduced into the first air flow path, flows through the narrow path NP to the second air flow path, reaches the maximum flow velocity in the narrow path NP, and reaches the induction exhaust port 25 from the reduced diameter portion 23. Released into the second air flow path. At this time, the exhaust gas discharged from the exhaust port 2 of the exhaust pipe 1 is forcibly attracted into the second air flow path in which the exhaust gas in the outer peripheral portion has a negative pressure, and the normal exhaust speed. It flows in the second air flow path at a higher speed and is discharged from the induction exhaust port 25. Further, the exhaust gas discharged from the axial center portion of the exhaust port 2 flows into the rectifying unit 40 and flows, but at this time, the gap of the minute gap d between the mounting unit 10 and the rectifying unit 40 is also used. Then, it is attracted to the downstream side in the axial direction by the negative pressure of the second air flow path, flows in the rectifying unit 40 at a speed higher than the normal discharge speed, and is discharged from the outlet 42. At the same time, the inner space of the rectifying unit 40 has a negative pressure at the tip thereof due to the venturi effect of the enlarged diameter portion 43. Therefore, the exhaust gas in the rectifying portion 40 is somewhat in the negative pressure portion in the enlarged diameter portion 43 at the tip. It is attracted and discharged from the outlet 42 at a higher speed. Further, at this time, the exhaust gas is rectified by the rectifying unit 40 that is coaxial with the exhaust pipe 1 and is discharged from the outlet 42 in a state in which the exhaust efficiency is further improved. As a result, the fuel efficiency improving device for a vehicle exhaust pipe according to the second embodiment can further improve the exhaust efficiency from the exhaust pipe 1, and can further reduce the fuel consumption and further improve the fuel efficiency. The enlarged diameter portion 43 at the tip of the rectifying unit 40 may be omitted, or the tip of the rectifying unit 40 may have the same diameter as that of the other parts and may have a simple cylindrical shape. There is no serious loss.

実施の形態3
本発明の実施の形態3に係る車両排気管用燃費向上装置は、図13に示すように、実施の形態2の車両排気管用燃費向上装置において、外筒部20の内部に装着部10をそれぞれ連結固定するための追加の一対の連結片33を設けている。その他の構成は、基本的に、実施の形態2の車両排気管用燃費向上装置と同様である。詳細には、前記連結片31から切欠部13に向かって約90度隔てた一方の角度位置と、連結片31から切欠部13と反対側に約90度隔てた他方の角度位置との2つの位置に、それぞれ、上流側拡径部21と装着部10とを連結する一方の連結片33及び他方の連結片33が、同一の半径方向に延びるよう設けられている。即ち、連結片31,33は、全て、切欠部13と重ならないよう、切欠部13とは異なる角度位置で全体として十字状となるよう合計4個設けられている。また、前記連結片32は、これら連結片33と同一角度位置に設けられている。
Embodiment 3
As shown in FIG. 13, the vehicle exhaust pipe fuel consumption improvement apparatus according to Embodiment 3 of the present invention is the same as that of the vehicle exhaust pipe fuel consumption improvement apparatus of Embodiment 2, the mounting portion 10 is connected to the inside of the outer cylinder portion 20. An additional pair of connecting pieces 33 for fixing is provided. Other configurations are basically the same as those of the vehicle exhaust pipe fuel consumption improvement apparatus of the second embodiment. Specifically, there are two angular positions, one angular position separated from the connecting piece 31 toward the notch 13 by about 90 degrees, and the other angular position separated from the connecting piece 31 by about 90 degrees on the opposite side to the notch 13. One connecting piece 33 and the other connecting piece 33 that connect the upstream-side enlarged-diameter portion 21 and the mounting portion 10 are provided at positions so as to extend in the same radial direction. That is, a total of four connecting pieces 31 and 33 are provided so as to form a cross shape as a whole at an angular position different from the notch portion 13 so as not to overlap the notch portion 13. The connecting piece 32 is provided at the same angular position as the connecting pieces 33.

上記のように構成した実施の形態3の車両排気管用燃費向上装置は、実施の形態2の車両排気管用燃費向上装置と同様にして、排気管1の排気口2に装着され、同様の作用効果を発揮する。特に、実施の形態3の車両排気管用燃費向上装置は、外筒部20及び装着部10の相互の連結のために、連結片31及び連結片33が、周方向に合計4箇所の角度位置で(等角度間隔で十字状となるよう)設けられるため、外筒部20及び装着部10の相互の連結をより強固かつ安定的に行うことができ、特に、ディーゼルエンジン車等の排気管1の振動の大きいものに装着した場合に、その装着安定性を向上し、予期しない離脱等の不具合を効果的に防止することができる。なお、追加の連結片33は、連結片31と90度隔てた位置に配置することが好ましいが、その他の角度位置に設けることも可能である。   The vehicle exhaust pipe fuel consumption improvement apparatus of the third embodiment configured as described above is mounted on the exhaust port 2 of the exhaust pipe 1 in the same manner as the vehicle exhaust pipe fuel consumption improvement apparatus of the second embodiment, and has the same effect. Demonstrate. In particular, in the fuel efficiency improving device for a vehicle exhaust pipe according to the third embodiment, the connecting piece 31 and the connecting piece 33 are provided at a total of four angular positions in the circumferential direction for mutual connection of the outer cylinder part 20 and the mounting part 10. Since the outer cylinder part 20 and the mounting part 10 can be connected to each other more firmly and stably, the exhaust pipe 1 of a diesel engine vehicle or the like can be connected. When mounted on a device with large vibrations, the mounting stability can be improved and problems such as unexpected detachment can be effectively prevented. In addition, although it is preferable to arrange | position the additional connection piece 33 in the position 90 degree apart from the connection piece 31, it is also possible to provide in another angular position.

実施の形態4
本発明の実施の形態4に係る車両排気管用燃費向上装置は、図14〜図16に示すように、実施の形態2の車両排気管用燃費向上装置において、外筒部20と基本的に同様の構成の外筒部50の上流側拡径部21の基端に連続して、更に、補助拡径部51を設けている。その他の構成は、基本的に、実施の形態2の車両排気管用燃費向上装置と同様である。詳細には、外筒部50の補助拡径部51は、上流側拡径部21の基端の外気導入口24から更に上流側に同軸状に延び、かつ、上流側拡径部21の縮径度合(テーパー角度)より若干小さい縮径度合(テーパー角度)の円錐台筒状をなしている。なお、補助拡径部51は、外筒部50の全周にわたって設けられる。これにより、補助拡径部51の基端の開口は、外気導入口24より大径の円形の拡大導入口52となっている。
Embodiment 4
The vehicle exhaust pipe fuel consumption improvement apparatus according to Embodiment 4 of the present invention is basically the same as the outer cylinder portion 20 in the vehicle exhaust pipe fuel consumption improvement apparatus of Embodiment 2 as shown in FIGS. An auxiliary enlarged diameter portion 51 is further provided continuously to the proximal end of the upstream enlarged diameter portion 21 of the outer cylinder portion 50 having the configuration. Other configurations are basically the same as those of the vehicle exhaust pipe fuel consumption improvement apparatus of the second embodiment. Specifically, the auxiliary enlarged diameter portion 51 of the outer cylinder portion 50 extends coaxially further from the outside air inlet 24 at the proximal end of the upstream enlarged diameter portion 21 to the upstream side, and the upstream enlarged diameter portion 21 is reduced. It has a truncated cone shape with a degree of diameter reduction (taper angle) slightly smaller than the degree of diameter (taper angle). The auxiliary enlarged diameter portion 51 is provided over the entire circumference of the outer cylinder portion 50. Thereby, the opening at the base end of the auxiliary enlarged diameter portion 51 is a circular enlarged introduction port 52 having a larger diameter than the outside air introduction port 24.

Demonstrate. In particular, in the fuel efficiency improving device for a vehicle exhaust pipe of the fourth embodiment, since the auxiliary diameter increasing portion 51 is provided on the base end side that is the outside air introduction side of the outer cylinder portion 50, the first auxiliary diameter increasing portion 51 having a larger diameter is used. The amount of outside air introduced into the air flow path can be dramatically increased, and the negative pressure of the second air flow path can be further increased (reduced pressure), and the exhaust efficiency of the exhaust gas from the exhaust pipe 1 can be increased. The fuel consumption can be further reduced and the fuel consumption can be further improved.

実施の形態5
本発明の実施の形態5に係る車両排気管用燃費向上装置は、図17に示すように、実施の形態4の車両排気管用燃費向上装置において、外筒部50の補助拡径部51を円周方向に2分割して下側補助拡径部51A及び上側補助拡径部51Bとしたものである。その他の構成は、基本的に、実施の形態4の車両排気管用燃費向上装置と同様である。詳細には、外筒部50の下側補助拡径部51Aは、上流側拡径部21の外気導入口24の下側(切欠部13と反対側の180度の範囲)に一体形成される一方、上側補助拡径部51Bは、上流側拡径部21の外気導入口24の上側(切欠部13側の180度の範囲)に着脱自在に取り付けられる。
Embodiment 5
As shown in FIG. 17, the vehicle exhaust pipe fuel consumption improvement apparatus according to Embodiment 5 of the present invention is the same as the vehicle exhaust pipe fuel consumption improvement apparatus of Embodiment 4 except that the auxiliary enlarged diameter portion 51 of the outer cylinder portion 50 is circumferentially arranged. The lower auxiliary enlarged diameter portion 51A and the upper auxiliary enlarged diameter portion 51B are divided into two in the direction. Other configurations are basically the same as those of the vehicle exhaust pipe fuel consumption improvement apparatus of the fourth embodiment. Specifically, the lower auxiliary enlarged diameter portion 51A of the outer cylinder portion 50 is integrally formed below the outside air introduction port 24 of the upstream enlarged diameter portion 21 (a range of 180 degrees opposite to the notch portion 13). On the other hand, the upper auxiliary enlarged diameter portion 51B is detachably attached to the upper side of the outside air introduction port 24 of the upstream enlarged diameter portion 21 (a range of 180 degrees on the notch 13 side).

上記のように構成した実施の形態5の車両排気管用燃費向上装置は、実施の形態2の車両排気管用燃費向上装置と同様にして、排気管1の排気口2に装着され、同様の作用効果を発揮する。特に、実施の形態5の車両排気管用燃費向上装置は、外筒部50に2分割した下側補助拡径部51A及び上側補助拡径部51Bを設けたため、車両の型によっては排気管1と車両の外部床面との間の隙間が狭小となる場合でも、上側補助拡径部51Bを外筒部50から取り外すことにより、排気管1に円滑かつ確実に装着することができ、同時に、下側補助拡径部51Aにより第1の空気流路内への外気の導入量を飛躍的に増大して、第2の空気流路の負圧を一層大きく(減圧)することができ、排気管1からの排気ガスの排気効率を一層向上してすることができ、燃料消費量を更に低減して燃費をより向上することができる。このため、排気管1と車両の外部床面との間の隙間が狭小となる車両の排気管1に装着する場合には、実施の形態5の車両排気管用燃費向上装置は、切欠部13が上側(車両の床面と対向する位置)にくるよう、装着部10を介して排気管1に装着する。なお、下側補助拡径部51Aと上側補助拡径部51Bは、それぞれ180度の角度範囲に設ける(その延設範囲を180度とする)以外にも、排気管1への装着が可能な限りにおいて、一方の角度範囲を他方の角度範囲より大きくしたり小さくしたりする(例えば、上側補助拡径部51Bを100度程度とし、下側補助拡径部51Aを260度程度とする)ことも可能である。下側補助拡径部51Aの角度範囲を大きくすれば、それだけ内部への外気導入量を増大することができる。   The vehicle exhaust pipe fuel consumption improvement apparatus of the fifth embodiment configured as described above is mounted on the exhaust port 2 of the exhaust pipe 1 in the same manner as the vehicle exhaust pipe fuel consumption improvement apparatus of the second embodiment. Demonstrate. In particular, the fuel efficiency improving device for a vehicle exhaust pipe according to the fifth embodiment is provided with the lower auxiliary enlarged diameter portion 51A and the upper auxiliary enlarged diameter portion 51B which are divided into two in the outer cylinder portion 50. Therefore, depending on the type of the vehicle, Even when the gap between the vehicle and the outer floor surface is narrow, by removing the upper auxiliary enlarged diameter portion 51B from the outer cylinder portion 50, the exhaust pipe 1 can be mounted smoothly and reliably, and at the same time, The amount of outside air introduced into the first air flow path can be dramatically increased by the side auxiliary enlarged diameter portion 51A, and the negative pressure of the second air flow path can be further increased (reduced pressure). The exhaust efficiency of the exhaust gas from 1 can be further improved, the fuel consumption can be further reduced, and the fuel consumption can be further improved. For this reason, in the case where the exhaust pipe 1 is mounted on the exhaust pipe 1 of the vehicle in which the gap between the exhaust pipe 1 and the outer floor surface of the vehicle is narrow, the notch portion 13 is provided in the vehicle exhaust pipe fuel efficiency improvement device of the fifth embodiment. The exhaust pipe 1 is mounted via the mounting portion 10 so as to be on the upper side (position facing the vehicle floor). The lower auxiliary enlarged diameter portion 51A and the upper auxiliary enlarged diameter portion 51B can be attached to the exhaust pipe 1 in addition to being provided in an angular range of 180 degrees (the extended range is 180 degrees). As long as one angle range is made larger or smaller than the other angle range (for example, the upper auxiliary enlarged portion 51B is set to about 100 degrees and the lower auxiliary enlarged portion 51A is set to about 260 degrees). Is also possible. If the angle range of the lower auxiliary enlarged diameter portion 51A is increased, the amount of outside air introduced into the interior can be increased accordingly.

ところで、本発明の車両排気管用燃費向上装置は、排気管1の温度上昇に対する耐熱性や排気ガス等による腐食防止等の観点からは、ステンレス鋼等の耐腐食板材乃至金属板材を曲げ加工、溶接加工等して形成することが好ましいが、上記のような構成とする限りにおいて、通常の鉄鋼材や樹脂材料等、任意の材料により形成することができる。また、装着部10による排気管1への取付方法も、排気管1に安定して取付可能な限りにおいて、上記以外の任意の方法を採用することができる。   By the way, the fuel efficiency improving device for a vehicle exhaust pipe according to the present invention bends and welds a corrosion-resistant plate material or a metal plate material such as stainless steel from the viewpoint of heat resistance against temperature rise of the exhaust pipe 1 and corrosion prevention by exhaust gas or the like. Although it is preferable to form by processing etc., as long as it is set as the above structures, it can form with arbitrary materials, such as a normal steel material and a resin material. Moreover, as long as the attachment part 10 can be attached to the exhaust pipe 1 as long as it can be stably attached to the exhaust pipe 1, any method other than the above can be adopted.
