Description

本発明は、内燃機関に用いられる燃焼ガス排出用排気具に関し、より詳しくは、自動車の排気ガスの排出経路に設けられる消音器のテールパイプに空気の流れを用いて排気逆流を抑止し、バックプレッシャーを低減して排気ガスを迅速に排出させて燃費と出力向上に有用な自動車用排気具に関する。   The present invention relates to an exhaust device for exhausting combustion gas used in an internal combustion engine. More specifically, the present invention relates to an exhaust device for suppressing exhaust gas backflow by using an air flow in a tail pipe of a silencer provided in an exhaust gas exhaust path of an automobile. The present invention relates to an exhaust device for an automobile that is useful for improving fuel efficiency and output by reducing exhaust pressure and exhausting gas quickly.

周知の通り、内燃機関を用いる自動車においては、吸入、圧縮、爆発、排気の４行程によって動力が得られる。   As is well known, in an automobile using an internal combustion engine, power is obtained by four strokes of suction, compression, explosion, and exhaust.

前記機関の行程のうち、空気（吸、排気）の流れを説明すると、吸入過程でエアークリーナ、スロットル弁などを通過する際には比較的に大きな抵抗なしに流入が行われる。   The flow of air (intake and exhaust) in the stroke of the engine will be described. When the air passes through the air cleaner, the throttle valve, etc., the inflow is performed without a relatively large resistance.

しかしながら、排気過程では排気マニホールド、触媒を用いる空気浄化装置及び消音器などを経てテールパイプに排気されることにより、排気の流れに相当な抵抗が発生する。   However, in the exhaust process, exhaust gas is exhausted to the tail pipe through an exhaust manifold, an air purification device using a catalyst, a silencer, and the like, thereby generating a considerable resistance to the exhaust flow.

前記機関のシリンダから消音器のテールパイプまで排出される過程において、排気マニホールドでは機関の４行程中に吸気弁と排気弁とが瞬間的に同時に開放される、いわゆる弁オーバーラップが発生する時期があり、この過程で排出されたガスがシリンダ内に再び流入する現象が発生しながら瞬間的に排気マニホールド内には真空状態が形成され、これにより、排気ガスの排出を妨げる１次バックプレッシャーが形成される。   In the process of discharging from the engine cylinder to the silencer tail pipe, the exhaust manifold has a timing when a so-called valve overlap occurs, in which the intake valve and the exhaust valve are instantaneously opened simultaneously during the four strokes of the engine. There is a phenomenon that the gas discharged in this process flows into the cylinder again, and a vacuum state is instantaneously formed in the exhaust manifold, thereby forming a primary back pressure that prevents the exhaust gas from being discharged. Is done.

また、空気浄化器である３次元触媒装置ではハニカム状の排気ガス浄化器の微細な通気孔を経由しながら排気ガスの流速が顕著に減少し、２次的なバックプレッシャーが形成され、消音器に流入すれば、多段に区画された仕切りを回って吸音されるとき、３次バックプレッシャーが形成される。   Further, in the three-dimensional catalyst device that is an air purifier, the exhaust gas flow rate is remarkably reduced through the fine ventilation holes of the honeycomb-shaped exhaust gas purifier, and a secondary back pressure is formed. If it flows in, the third back pressure is formed when sound is absorbed around the multi-partitioned partitions.

このような排気過程で排気ガスは、３〜５Ｋｇ／ｃｍ３の圧力と６００℃程度の温度で排気されて消音器が必ず必要であり、消音器は大体排気量の１５〜２０倍の容積に設計され、このような消音器は空気抵抗によって機関の燃焼ガスが円滑に排出されず、出力の５〜１０％が減少してしまうという不具合がある。 In such an exhaust process, the exhaust gas is exhausted at a pressure of 3 to 5 kg / cm 3 and a temperature of about 600 ° C., and a silencer is absolutely necessary. The silencer has a volume approximately 15 to 20 times the displacement Designed, such a silencer has a problem that the combustion gas of the engine is not smoothly discharged due to air resistance, and 5 to 10% of the output is reduced.

従って、前記排気ガスを円滑に排出させるだけでも機関の出力向上と燃費を改善できることが分かる。   Therefore, it can be seen that the engine output can be improved and the fuel consumption can be improved simply by exhausting the exhaust gas smoothly.

前記のように、排気ガスの排出を円滑にするために従来も多様な提案が公知されている。   As described above, various proposals have been conventionally known in order to smoothly discharge exhaust gas.

下記の特許文献１は、空気の流れを用いた自動車の排気筒を提案しており、これは自動車の走行による空気の流れを用いて流線形の排気具本体をテールパイプに結合して流線形の本体を通り過ぎる空気の流速に応じて低圧地域が形成されるようにし、この低圧によって排気ガスが急速に吸い出されながら、排気を助けるようになっている。   The following Patent Document 1 proposes an automobile exhaust pipe using an air flow, which is connected to a tailpipe using a stream of air generated by running of the automobile to connect the tail pipe to the streamline. A low pressure region is formed according to the flow velocity of the air passing through the main body of the gas, and the exhaust gas is sucked out rapidly by this low pressure to assist the exhaust.

しかしながら、このような流線形の排気具本体を自動車に取り付けるには構造的に巨大かつ複雑であるという短所があり、停止又は低速走行時には速い空気の流れを誘導できず、狭い排気通路のみではむしろ排気を妨げるという問題があり、実用性は低い。   However, there is a disadvantage that it is structurally huge and complicated to attach such a streamlined exhaust body to an automobile, and it is not possible to induce a fast air flow when stopping or running at low speed, but rather only with a narrow exhaust passage There is a problem of hindering exhaust, and its practicality is low.

また、下記の特許文献２の渦流発生装置を有するメインサイレンサのテールパイプによれば、テールパイプの中間に渦流用翼を排気ガスによって回動するように設けたものであって、排気ガスによって翼が回転しながら、渦流が発生して排気するように提案しているが、これはむしろ排気ガスの流れを妨害する抵抗を提供するので、実質的に使用し難いという問題がある。   Further, according to the tail pipe of the main silencer having the vortex generator of Patent Document 2 below, the vortex wing is provided in the middle of the tail pipe so as to be rotated by the exhaust gas. However, it is proposed that the vortex flow is generated and exhausted while rotating, but this provides a resistance to disturb the flow of the exhaust gas, so that it is substantially difficult to use.

下記の特許文献３の自動車排気ガス排出装置によれば、テールパイプの終端にボルトで取り付けられるパイプを設け、パイプの内周縁に渦流形成用翼を放射状に多数形成してなるものであって、排気ガスを渦流させて排出効率を改善するために提案されたが、このように単に排気ガスを渦流させるだけでは急速かつ円滑に排気させるには不十分であり、結果的には、バックプレッシャー力で自然排気されることに加えて、流体の渦流が排気を部分的に助ける程度の極僅かな効果が得られる程度に過ぎず、効率は極めて低い。   According to the automobile exhaust gas discharge device of Patent Document 3 below, a pipe attached with a bolt is provided at the end of the tail pipe, and a large number of vortex forming blades are radially formed on the inner peripheral edge of the pipe, Although it has been proposed to improve exhaust efficiency by swirling the exhaust gas, simply swirling the exhaust gas in this way is insufficient to exhaust quickly and smoothly, and as a result, the back pressure force In addition to being naturally evacuated, the efficiency is very low, with only a negligible effect that the vortex of the fluid partially assists the evacuation.

更に、下記の特許文献４の渦流を用いた排気ガス排出装置によれば、排気ガス経路に形成されている消音器の前方のパイプに外部空気を流入させ、渦流を形成するベーンを有する渦流発生ダクトを形成し、スロットル弁の開放量に比例して開度が調節される弁が内設されているサブダクトを含んでなる。   Furthermore, according to the exhaust gas exhaust apparatus using the vortex flow described in Patent Document 4 below, eddy current generation having a vane that forms a vortex by letting external air flow into the pipe in front of the silencer formed in the exhaust gas path. It includes a sub duct in which a duct is formed and a valve whose opening degree is adjusted in proportion to the opening amount of the throttle valve is provided.

しかしながら、これは排気騷音を除去するための消音器の前段パイプに外気が流入するダクトを形成するので、排気騷音がこのダクトに漏れ出て騷音が大きく発生し、加速時には弁が大きく開放されて排気騷音が更に大きく発生するという不具合があり、排気ガスが、消音器の内部に比べて空気抵抗の弱いサブダクトに排出されるので、流入空気が抵抗を受けて実用化し難いという問題がある。   However, this forms a duct through which the outside air flows into the front pipe of the silencer for removing the exhaust noise, so that the exhaust noise leaks into this duct and a large noise is generated, and the valve is large during acceleration. There is a problem that exhaust noise is generated even more when it is opened, and exhaust gas is exhausted to a sub duct with a lower air resistance compared to the inside of the silencer, so that the inflow air receives resistance and is difficult to put into practical use. There is.

更に、前記従来技術は外気が消音器の流入口側に流入されるようにすることによって、消音器内部における空気抵抗はそのまま存在するので、排気を速やかに行うのに有用でないだけでなく、機関のスロットル弁と連動する外気調節用ダンパを構成するため、設備構造及び施設が複雑になるという問題が生じ、外気が流入して消音器を経由するようになるので、消音器内部に外気に含まれている異物（粉塵、砂など）が沈積して消音器の機能を低下させるという短所がある。   Furthermore, since the conventional technology allows outside air to flow into the inlet side of the silencer, the air resistance in the silencer exists as it is. Since the damper for adjusting the outside air that works with the throttle valve of the system is constructed, there is a problem that the equipment structure and facilities become complicated, and the outside air flows in and goes through the silencer, so it is included in the outside air inside the silencer There is a disadvantage that the foreign matter (dust, sand, etc.) that has been deposited accumulates and the function of the silencer is lowered.

本発明者は、前記問題点を解決するために、下記の特許文献５の自動車用排気具を提案した。   In order to solve the above-mentioned problems, the present inventor has proposed an automobile exhaust device of Patent Document 5 below.

前記特許は自動車の走行による外気を拡開したラッパ管に集めて排気用テールパイプの排気圧を高めることで、流速を速やかにする構造をなしている。   The patent has a structure that speeds up the flow rate by collecting the outside air from the traveling of the automobile in an expanded trumpet and increasing the exhaust pressure of the exhaust tailpipe.

即ち、外部空気をラッパ管に集めて小さな断面積を通過する空気圧が増加することにより、排気パイプの排出ガスが迅速に排出されるようになっている。   That is, the exhaust gas from the exhaust pipe is quickly discharged by increasing the air pressure passing through the small cross-sectional area by collecting the external air in the trumpet.

このような先願発明は、排気流速の増加を実現して出力と燃費の向上にある程度メリットはあったものの、これらの提案も停車中であるか、低速で走行する場合にはその効果が多少不十分である。   Although this prior invention has some advantages in improving the output and fuel consumption by increasing the exhaust flow velocity, these proposals are also somewhat effective when stopped or running at low speed. It is insufficient.

また、本発明者は下記の特許文献６でテールパイプに一端を切り欠いて内向きに折り曲げた固定ベーンを離間して２箇所に設けて速い排気気流を形成し、オーバーラップ時に逆流入する外気を前記ベーンに排出するようになり、エンジンの出力を増大できるように提案したほか、特許文献７を通じて自動車の消音器終端のテールパイプに一端を切り欠いて内向きに折り曲げた第１、２固定ベーン１、２を設け、互いに一定距離だけ離間し、対向するようになされ、前記第１、２固定ベーンを取り囲んで第１、２固定ベーンが相互連通し、大気と密閉する管体３からなる循環排気具を結合して消音器の排気終端に速い空気の流れを誘発させるように提案するなど多数の排気具に関する発明を行った。   In addition, in the following Patent Document 6, the present inventor forms a quick exhaust airflow by separating fixed vanes that are notched at one end of the tail pipe and bent inward to form a fast exhaust airflow, and the outside air that flows back in the overlap state. In order to increase the engine output, the first and second fixings in which the tail pipe at the end of the silencer of the automobile is notched and bent inward through Patent Document 7 are proposed. The vanes 1 and 2 are provided, are spaced apart from each other by a predetermined distance, and are opposed to each other. The pipes 3 surround the first and second fixed vanes, and the first and second fixed vanes communicate with each other and are sealed with the atmosphere. Inventions related to a number of exhaust devices such as a proposal to induce a fast air flow at the exhaust end of a silencer by connecting a circulation exhaust device have been made.

本発明は前述したような従来技術の有する問題点と、本発明者の先出願技術を改良して効率を増大させるためになされたものであって、以下のような目的を有する。   The present invention has been made in order to increase the efficiency by improving the problems of the prior art as described above and the prior application technique of the present inventor, and has the following objects.

本発明の目的は、消音器のテールパイプを介して排出される排気ガスがベンチュリ現象により排気速度を高め、流入した外気を循環排出させて排気速度を加速させ、排気ガスの排出を迅速に行えるようにした自動車用排気具を提供することにある。   The object of the present invention is to exhaust the exhaust gas exhausted through the tail pipe of the silencer to increase the exhaust speed by the venturi phenomenon, to circulate and exhaust the inflowing outside air to accelerate the exhaust speed, and to quickly exhaust the exhaust gas. An object of the present invention is to provide an exhaust device for an automobile.

また、本発明の他の目的は、排気ガスの排出は迅速に行われるようにし、逆流する排気ガスをテールパイプから大気に循環排出させることにより、排気ガスが機関に再び流入したり、バックプレッシャーとして作用したりする不具合を解消してエンジンの出力増大を達成できるようにした自動車用排気具を提供することにある。   Another object of the present invention is to exhaust the exhaust gas quickly, and to circulate and exhaust the exhaust gas flowing backward from the tail pipe to the atmosphere, so that the exhaust gas flows back into the engine or back pressure. It is an object of the present invention to provide an exhaust device for an automobile which can solve the problem of acting as an engine and achieve an increase in engine output.

本発明の更に他の目的は、堅固な構造をなすことにより、耐久性が顕著に増大し、既存の消音器の構造を変更することなく、適用が可能であり、互換性の優れた自動車用排気具を提供することにある。   Still another object of the present invention is to increase the durability remarkably by making a rigid structure, and can be applied without changing the structure of an existing silencer, and has excellent compatibility. It is to provide an exhaust device.

本発明の更に別の目的は、排気ガスの逆流を極減させてカーボンなどの燃焼残留物の堆積を低減させることで、エンジンの寿命を延ばすと共に、高価な煤煙浄化装置など排気系統の多様な部品をクリーンに保って寿命を増大させる自動車用排気具を提供することにある。   Still another object of the present invention is to reduce the backflow of exhaust gas and reduce the accumulation of combustion residues such as carbon, thereby extending the life of the engine and various exhaust systems such as an expensive soot purifier. It is an object of the present invention to provide an automotive exhaust that keeps parts clean and increases life.

前記目的を達成するための本発明は、自動車の排気ガスの流れを改善するために消音器のテールパイプに嵌合する排気具であって、延長管体として、その排気流入端には流速増大のためのベンチュリ管路を形成する延長管体と、前記ベンチュリ管路の内側に延長突出した外気排出ノズルと、管体の排気排出終端には外気の流入を誘導する逆流進入口と、前記逆流進入口と外気排出ノズルとが連通するようにチャンバを限定するよう前記延長管体に取り付けられたカバーを含む。したがって、排気終端で速い空気の流れと逆流流入を抑止して排気を改善するので、出力が向上する。   In order to achieve the above object, the present invention provides an exhaust device fitted to a tail pipe of a silencer in order to improve an exhaust gas flow of an automobile, and has an increased flow velocity at its exhaust inflow end as an extension tube. An extension tube forming a venturi conduit for the tube, an outside air discharge nozzle extending and projecting to the inside of the venturi conduit, a reverse flow inlet for inducing the inflow of outside air at the exhaust discharge end of the tube, and the reverse flow A cover attached to the extension tube to limit the chamber so that the inlet and the outside air discharge nozzle communicate with each other. Therefore, the exhaust is improved by suppressing the fast air flow and the reverse flow inflow at the exhaust end, and the output is improved.

本発明によれば、排気ガスが排出される消音器のテールパイプに付加的に循環排気具を別途形成して結合するので、既存の排気系統を大きく設計変更することなく、簡単に取り付けることができ、排出される排気ガスがベンチュリ現象により速く排出されると共に逆流流入する外気が逆気流として流入することを遮断し、チャンバ内部に受け入れられて循環排出するので、排気系統のバックプレッシャーを抑止して排気効率を改善し、エンジンの出力を高めるという効果を奏する。また、構造的に外気排出ノズルと逆流進入口の設計を可変的に形成してチャンバ内部の低圧設計を容易にし、簡単かつ堅固な構造をなすことにより、耐久性が顕著に増大し、既存の消音器の構造を変更することなく、適用が可能であり、互換性に優れていると共に、排気ガスの逆流を極減させてカーボンなどの燃焼残留物の堆積を低減させてエンジンの寿命を延ばし、高価な煤煙浄化装置など排気系統の多様な部品をクリーンに保って寿命を増大させるなどの様々な効果を有する。なお、本発明の主な説明は自動車の排気具を対象にしているが、内燃機関を使う全ての消音器のテールパイプに適用可能である。   According to the present invention, since the circulation exhaust tool is additionally formed and coupled to the tail pipe of the silencer from which exhaust gas is exhausted, it can be easily attached without changing the design of the existing exhaust system. The exhaust gas is exhausted quickly due to the venturi phenomenon, and the outside air that flows back in is blocked from flowing in as a back air flow, and is received inside the chamber and circulated and exhausted, so the back pressure of the exhaust system is suppressed. This has the effect of improving exhaust efficiency and increasing engine output. In addition, the design of the outside air discharge nozzle and the reverse flow inlet is variably formed to facilitate the low pressure design inside the chamber, and the simple and robust structure makes the durability significantly increased. It can be applied without changing the structure of the silencer, has excellent compatibility, and minimizes exhaust gas backflow to reduce the accumulation of combustion residues such as carbon, thereby extending the life of the engine. It has various effects such as keeping various parts of the exhaust system clean, such as an expensive soot purifier, and increasing the service life. Although the main description of the present invention is directed to an automobile exhaust, it can be applied to the tail pipes of all silencers that use an internal combustion engine.

以下、添付する図面を参照して詳細に説明する。   Hereinafter, a detailed description will be given with reference to the accompanying drawings.

添付する図２〜図４には本発明の基本的な実施形態が示されている。   2 to 4 of the accompanying drawings show basic embodiments of the present invention.

自動車の消音器終端のテールパイプに嵌合する延長管体１０からなり、前記管体の排気流入端には流速の増大のための管径が狭いベンチュリ管路２０を形成し、前記ベンチュリ管路２０の内側に管路から延長突出した外気排出ノズル３０を形成し、管体の排気排出終端には外気の流入を誘導する逆流進入口４０を形成して前記逆流進入口４０と外気排出ノズル３０とが連通するようにチャンバ５２を限定するよう延長管体１０に取り付けられたカバー５０を形成し、循環排気具１００をなす。   It comprises an extension tube 10 fitted to a tail pipe at the end of a silencer of an automobile, and a venturi pipe 20 having a narrow pipe diameter for increasing the flow velocity is formed at the exhaust inflow end of the pipe. An outside air discharge nozzle 30 extending from the pipe line is formed on the inside of the pipe 20, and a backflow inlet 40 for inducing the inflow of outside air is formed at the exhaust discharge end of the tube body. A cover 50 attached to the extension tube 10 is formed so as to limit the chamber 52 so as to communicate with each other.

一方、本発明は、図５に示すように、前記ベンチュリ管路２０の内径に両端が拡張した第２ベンチュリ管路２２を更に形成し、前記外気排出ノズル３０を長く延ばして前記第２ベンチュリ管路２２内にノズル端部を連通し、管路２２はベンチュリ管路２０の中心に前記ノズル３０によって支持するように形成する。   On the other hand, in the present invention, as shown in FIG. 5, a second venturi pipe 22 having both ends expanded on the inner diameter of the venturi pipe 20 is further formed, and the outside air discharge nozzle 30 is extended to extend the second venturi pipe. A nozzle end is communicated with the passage 22, and the conduit 22 is formed so as to be supported by the nozzle 30 at the center of the venturi conduit 20.

前記管体１０からベンチュリ管路２０内に延長形成した外気排出ノズル３０は排気方向に傾斜するように形成し、ノズルはチャンバ５２側から排出終端に向かうほど、次第に狭くなるように傾斜面の管体からなる。   An outside air discharge nozzle 30 extending from the tube body 10 into the venturi pipe line 20 is formed so as to be inclined in the exhaust direction, and the nozzle is inclined so that the nozzle gradually becomes narrower from the chamber 52 side toward the discharge end. Consists of the body.

また、前記外気排出ノズル３０は、好ましくは、２〜４本のうち選択的に形成してなることもできる(図３参照）。   In addition, the outside air discharge nozzle 30 may preferably be formed selectively from 2 to 4 (see FIG. 3).

Yes (see FIG. 4).

図示していない符号１６は、消音器のテールパイプに管結合するために形成したスリットを示すものである。   Reference numeral 16 (not shown) indicates a slit formed for pipe connection to the tail pipe of the silencer.

前述したような技術構成を有する本発明の作用について以下で更に具体的に説明する。   The operation of the present invention having the technical configuration as described above will be described more specifically below.

前記本発明の循環排気具１００は、図６に示すように、通常の消音器６０テールパイプの外側の周囲に嵌め込み、クランプなどで固定結合して設置を容易にする。   As shown in FIG. 6, the circulating exhaust device 100 of the present invention is fitted around the outside of a normal silencer 60 tail pipe and fixedly coupled with a clamp or the like to facilitate installation.

エンジンの駆動により通常の過程を通じて排出される排気ガスが消音器に流入すれば、消音器６０の膨脹室で消音がなされた後、排出される。   If exhaust gas exhausted through a normal process by driving the engine flows into the silencer, the exhaust is silenced in the expansion chamber of the silencer 60 and then exhausted.

排出される排気ガスは、図７に示すように、本発明の循環排気具１００の管体１０に流入しながら、管体の狭くなった管径を有するベンチュリ管路２０で速い流速で進みながら、排気速度を高めるとともに、ベンチュリ管路２０内に延びた外気排出ノズル３０を介してチャンバ５２内の外気を引き込んで排気ガスと共に排出させてチャンバの内部には瞬間的な低圧が形成され、排気がなされた後に逆気流は低圧を形成した逆流進入口４０に吸い込まれる。   As shown in FIG. 7, the exhaust gas discharged flows into the tube body 10 of the circulating exhaust device 100 of the present invention and proceeds at a high flow velocity in the Venturi pipeline 20 having a narrow tube diameter. In addition to increasing the exhaust speed, the outside air in the chamber 52 is drawn through the outside air discharge nozzle 30 extending into the venturi pipe 20 and is discharged together with the exhaust gas, and an instantaneous low pressure is formed inside the chamber. Then, the backflow is sucked into the backflow inlet 40 that forms a low pressure.

これにより、逆気流はエンジン方向に作用せずに、循環排気具のチャンバ５２を介して再び排気されるサイクルで、前述したように、ベンチュリ管路に引き込まれて排出される過程が非常に速やかに繰り返されて発生する。   Thus, in the cycle in which the reverse airflow does not act in the engine direction and is exhausted again through the chamber 52 of the circulating exhaust device, the process of being drawn into the venturi conduit and exhausted as described above is very quick. Repeatedly occurs.

従って、負圧波を伴って排出されていた排気ガスは逆気流の負圧波が循環排気具によって除去されることで、バックプレッシャーを除去する作用をなす。   Therefore, the exhaust gas discharged with the negative pressure wave has a function of removing the back pressure by removing the negative pressure wave of the reverse airflow by the circulating exhaust tool.

ここで、吸気と排気が１秒当たりに数十回〜百数十回繰り返されるエンジンの駆動過程を見ると、排気ガスも排出と停止が数十〜百数十回繰り返されて発生するようになり、このとき、排気系統には正圧と負圧が繰り返されて起き、排気慣性を有する排出ガスは排気系統に負圧がかかる過程で外気の逆流入が発生し、この逆流入する気流がバックプレッシャーとして作用してエンジンの出力を低下させる副作用を伴っていたが、本発明は排気が瞬間的に停止した状態で排気慣性が作用する時点でチャンバ５２の内部は低圧を形成するようになって外気は相対的に低圧をなし、流入抵抗の小さな逆流進入口４０に流入が行われるので、排気系統に作用していた逆流によるバックプレッシャーを除去する。   Here, looking at the engine driving process in which intake and exhaust are repeated dozens to hundreds of times per second, exhaust gas is generated such that exhaust and exhaust are repeated dozens to hundreds and dozens of times. At this time, the positive and negative pressures are repeatedly generated in the exhaust system, and the exhaust gas having the exhaust inertia generates a reverse inflow of outside air in the process of applying a negative pressure to the exhaust system. Although it has a side effect of reducing the engine output by acting as a back pressure, the present invention forms a low pressure inside the chamber 52 when the exhaust inertia acts in a state where the exhaust stops instantaneously. Since the outside air has a relatively low pressure and flows into the backflow inlet 40 having a small inflow resistance, the back pressure due to the backflow acting on the exhaust system is removed.

従って、排気ガスが排出される消音器パイプへの排気ガスの排出は、更に急速に行われ、同時にエンジンのオーバーラップ時の排気ガスの逆気流は前記循環排気具１００で吸入と排出の循環がなされ、すぐに再排出されるので、逆流による排気流れの妨害が防止され、排気が円滑に行われるので、出力が増大し、燃料の低減効果と共に、排気系統に残留する燃焼異物の排出が円滑になされて排気系統の装備を保護し、寿命を長く延ばすことができるように作用する。   Accordingly, exhaust gas is exhausted more rapidly into the silencer pipe from which exhaust gas is exhausted. At the same time, the reverse exhaust airflow during the overlap of the engine is circulated between the intake and exhaust by the circulating exhaust device 100. Since the exhaust is immediately re-discharged, the exhaust flow is prevented from being obstructed by the back flow, and the exhaust is smoothly performed. Therefore, the output is increased, the fuel is reduced, and the combustion foreign matter remaining in the exhaust system is smoothly discharged. This protects the equipment of the exhaust system and acts to extend the service life.

前記のような構造による作用をなす本発明は、図５に示すように、変形実施されることもできる。   As shown in FIG. 5, the present invention having the above-described structure can be modified.

即ち、図５に示すような発明によれば、前述したベンチュリ管路２０とチャンバ５２の循環作用は同一であり、ベンチュリ管路２０の内径部分に第２ベンチュリ管路２２を更に付加して第２ベンチュリ管路２２を介して外気排出ノズル３０の外気循環排出をなし、ベンチュリ管路２０の速い流速に加えて更に速い排気流速を得る（図８参照）。   That is, according to the invention as shown in FIG. 5, the circulation action of the venturi conduit 20 and the chamber 52 described above is the same, and the second venturi conduit 22 is further added to the inner diameter portion of the venturi conduit 20. 2. The outside air discharge nozzle 30 is circulated and discharged through the two venturi line 22 to obtain a higher exhaust flow rate in addition to the fast flow rate of the venturi line 20 (see FIG. 8).

前記外気排出ノズル３０は、チャンバ５２側の流入端に比べて排出ノズル終端側に向かうほど、次第に狭くなるように傾斜面の管体をなすことによって、排気加速度を高める作用をする一方、排気ガスの進行方向に傾斜するように形成して排気の流れに抵抗を低減させるように作用する。   The outside air discharge nozzle 30 has a function of increasing exhaust acceleration by forming a tube body having an inclined surface so as to become gradually narrower toward the end of the discharge nozzle as compared to the inflow end on the chamber 52 side. It is formed so as to incline in the traveling direction of the gas, and acts to reduce the resistance to the flow of exhaust.

また、逆流進入口４０は循環排気具の最終端に位置するようにして流入する外気が排気ガスの排出管路内に流入することを最大限に抑止する作用をし、逆流進入口４０はチャンバ５２の内部が外気排出ノズル３０を通じて一時的な低圧状態を形成するように開口部の面積を選択的に調節して設計することができ、図示のように、２箇所又は２〜４箇所程度に同心円に沿って分散形成できる。   The reverse flow inlet 40 is located at the final end of the circulation exhaust tool, and acts to suppress the inflow of outside air into the exhaust gas discharge pipe as much as possible. 52 can be designed by selectively adjusting the area of the opening so that a temporary low pressure state is formed through the outside air discharge nozzle 30, as shown in FIG. It can be distributed along concentric circles.

前記技術の構成によって排気速度を加速して迅速に排出し、排気系統に作用するバックプレッシャーを循環排出する本発明は、図９に示すように、製作の容易性のために変形実施されることもできる。   As shown in FIG. 9, the present invention in which the exhaust velocity is accelerated and exhausted quickly by the above-described configuration and the back pressure acting on the exhaust system is circulated and exhausted is modified for ease of manufacturing as shown in FIG. You can also.

即ち、前記エンジのン排気ガスが排出される管体を流入側の第１管体１２と排出側の第２管体１４とに分離形成して、前記第１管体１２の一端にベンチュリ管路を形成するように狭い管路で形成したベンディング部１２ａを形成し、前記第２管体１４の一端にもベンディング部１４ａを形成してベンディング部１２a、１４ａを互いに対向させてカバー５２によって固定結合して狭い直径を有するベンディング部１２a、１４ａがベンチュリ管路として機能するとともに、リング状の外気排出ノズルを兼ねるようになっている。   In other words, a tube body from which the engine exhaust gas is discharged is separated into an inflow side first tube body 12 and an exhaust side second tube body 14, and a venturi tube is formed at one end of the first tube body 12. A bending part 12a formed by a narrow pipe line is formed so as to form a path, a bending part 14a is also formed at one end of the second tubular body 14, and the bending parts 12a and 14a are opposed to each other and fixed by a cover 52. The bending portions 12a and 14a having a narrow diameter by being combined function as a venturi conduit and also serve as a ring-shaped outside air discharge nozzle.

これは、外気排出ノズルをベンチュリ管路内に容易に製作できるという長所を有し、作用は前述した本発明の基本的な実施形態と同一であることが分かる。   This has the advantage that the outside air discharge nozzle can be easily manufactured in the Venturi line, and it can be seen that the operation is the same as the basic embodiment of the present invention described above.

前記分離形成した第１、２管体１２、１４は、構造的な堅固さを考慮して小幅な連結板１５を管体外径に放射状に溶接して形成することができる。   The first and second tubular bodies 12 and 14 formed separately can be formed by radially welding small connecting plates 15 to the outer diameter of the tubular body in consideration of structural rigidity.

前記のように、エンジンの排気ガスの流速を速くして迅速な排気を行うベンチュリ構造とベンチュリ管路の内部にチャンバ内部が低圧室を形成するように外気排出ノズルと逆流進入口を形成した排気具の構造は、特許請求の範囲に記載した技術により多様に設計されることができ、前記技術の要旨を含む変更が本発明の請求範囲に含まれることは明らかである。   As described above, the venturi structure that performs quick exhaust by increasing the flow rate of the exhaust gas of the engine and the exhaust in which the outside air discharge nozzle and the reverse flow inlet are formed so that the inside of the chamber forms a low-pressure chamber inside the venturi pipe It is apparent that the structure of the tool can be designed in various ways by the technology described in the claims, and modifications including the gist of the technology are included in the claims of the present invention.

一方、本発明の主な説明は自動車の排気具を対象にしたが、内燃機関を用いるあらゆる消音器のテールパイプへの適用が可能である。   On the other hand, although the main description of the present invention is directed to an automobile exhaust device, it can be applied to the tail pipe of any silencer using an internal combustion engine.
