Description
本創作係有關一種排氣管結構改良,尤指一種可同時增加扭力輸出及降低排氣噪音之排氣管結構設計。This creation relates to an improved exhaust pipe structure, especially an exhaust pipe structure design that simultaneously increases torque output and reduces exhaust noise.
按,隨著汽機車產業篷勃發展,使得汽機車的普及率愈來愈高,是一種使用相當方便的交通工具,然而在競爭激烈的汽機車市場中,若欲獲得消費者的青睞,不僅須具備有獨特之設計性,提升產品性能外,同時降低生產成本,提供產品價格優勢亦是一大因素。就排氣管而言,其主要有兩個作用,一是將引擎燃燒過後所排放的廢氣排出車外,並於排放廢氣的同時產生一返回汽缸的壓力即回壓,而為引擎排氣行程提供適當的環境,讓汽缸內混合氣能夠達到完全燃燒,二是利用消音器將排氣震波產生噪音降至可容許的限度。因此,車輛動力結構中,排氣系統佔有重要地位。According to the development of the automobile and motorcycle industry, the popularity of steam locomotives is getting higher and higher. It is a very convenient means of transportation. However, in the highly competitive automobile locomotive market, if you want to gain the favor of consumers, not only It is necessary to have a unique design to improve product performance, while reducing production costs, and providing product price advantage is also a major factor. As far as the exhaust pipe is concerned, it mainly has two functions. One is that the exhaust gas discharged after the engine is burned out of the vehicle, and the pressure of the returning cylinder, that is, the back pressure, is generated while the exhaust gas is exhausted, and the engine exhaust stroke is provided. The proper environment allows the internal combustion of the cylinder to achieve complete combustion. The second is to use a silencer to reduce the noise generated by the exhaust shock to an allowable limit. Therefore, the exhaust system occupies an important position in the vehicle power structure.
再者,由於排氣管回壓的強弱,關係著引擎動力的輸出,若回壓過強則會造成廢氣無法完全排出汽缸,使廢氣與混合氣一起燃燒,降低燃燒效率妨礙引擎轉速的上升;反之,若回壓過弱則會使混合氣燃燒不完全,而引響引擎動力輸出造成扭力不足。而一般排氣管回壓的設計,大都於消音器內部設置許多隔板,並利用隔板阻擋住廢氣衝出,此等設計不僅成本較高,且往往造成回壓過大,仍不理想。故,如何設計一種既簡易 又可以調配出最適當且穩定的排氣管回壓結構,為引擎排氣行程提供最佳的環境,乃有其市場之需求,更係消費者企盼的新型產品,亦係相關業者努力研發突破之目標。Furthermore, due to the strength of the back pressure of the exhaust pipe, it is related to the output of the engine power. If the back pressure is too strong, the exhaust gas cannot be completely exhausted from the cylinder, so that the exhaust gas is burned together with the mixed gas, and the combustion efficiency is lowered to hinder the increase of the engine speed; Conversely, if the back pressure is too weak, the mixture will not burn completely, and the engine power output will cause insufficient torque. In general, the design of the exhaust pipe back pressure is mostly provided with a plurality of partitions inside the muffler, and the baffles are blocked by the baffles. These designs are not only costly, but often cause excessive back pressure, which is still not ideal. Therefore, how to design a simple It can also allocate the most appropriate and stable exhaust pipe back pressure structure to provide the best environment for the engine exhaust stroke. It has the needs of the market, and is also a new type of product that consumers are looking forward to. The goal.
有鑑於此,本創作人針對上述目標,乃潛心研思、設計組製,期能開發出一種構造簡單、實用且具市場競爭力優勢之排氣管結構改良,以提供消費大眾使用,為本創作所欲研創之創作動機者。In view of this, the creators have focused on the above objectives, and have developed a design system that can be used to provide consumers with a simple, practical, and competitive market advantage. The creative motive of the creative research institute.
本創作之主要目的,在於提供一種能利用膨脹氣室之設計,使流經之廢氣形成氣體渦流現象,以有效降低排氣噪音及增加引擎扭力輸出之排氣管結構改良。The main purpose of this creation is to provide an exhaust pipe structure that can utilize the design of the expansion chamber to form a gas vortex phenomenon through the exhaust gas to effectively reduce exhaust noise and increase the output of the engine torque.
本創作之另一目的,在於提供一種整體結構設計簡單、容易生產製造之排氣管結構,具有價格之優勢,能提升產品市場之競爭力。Another object of the present invention is to provide an exhaust pipe structure which is simple in design and easy to manufacture and has the advantage of price, and can enhance the competitiveness of the product market.
為達上述之目的,本創作係於排氣管前端所設之進氣前管之管段間,對應的導接有一管徑較大之膨脹氣室設計,俾使引擎所排放之廢氣經此膨脹氣室後再導入消音器,最後由尾管排出,而該廢氣流經該膨脹氣室時則會形成一氣體渦流現象;因此,可透過此渦流所產生之擾動氣體吸收廢氣中的氣音,進而有效的降低排氣噪音,同時亦能使氣室中氣壓升高而產生適當的回壓,讓汽缸內混合氣能夠達到完全燃燒,有效提昇引擎扭力的輸出。In order to achieve the above purpose, the creation is between the pipe sections of the front inlet pipe provided at the front end of the exhaust pipe, and the corresponding guide has a design of an expansion chamber having a large diameter, so that the exhaust gas discharged from the engine is expanded by this. After the gas chamber is introduced into the muffler, and finally discharged from the tail pipe, the exhaust gas flows through the expansion gas chamber to form a gas vortex phenomenon; therefore, the disturbing gas generated by the vortex can absorb the gas sound in the exhaust gas. In addition, the exhaust noise is effectively reduced, and the air pressure in the air chamber is raised to generate an appropriate back pressure, so that the air-fuel mixture in the cylinder can achieve complete combustion, thereby effectively increasing the output of the engine torque.
如上所述之排氣管結構,其中於膨脹氣室內部更設有一隔板,且該隔板上分佈設有複數氣孔。The exhaust pipe structure as described above, wherein a partition is further disposed inside the expansion gas chamber, and a plurality of air holes are disposed on the partition.

The structure of the exhaust pipe 1 is improved. The structure of the exhaust pipe 1 is roughly the same as the conventional structure. An intake pipe 10 is provided at the front section. The front end of the tube 10 is provided with a joint 11 for connecting the exhaust gas to the engine, and the rear end of the front duct 10 is connected with a muffler 20, and the other end of the muffler 20 is connected with a tail pipe 30; The feature of the present invention is mainly that in the improved creation, the corresponding guide between the pipe sections of the intake front pipe 10 has a large diameter expansion chamber 12 .
使用時,當引擎運轉所排放之廢氣導入進氣前管10後,廢氣流經該膨脹氣室12時,氣體會產生迅速膨脹擴散之變化,進而形成一氣體渦流現象(如第2圖所示),藉此,即可透過此渦流現象,使膨脹氣室12中氣壓升高而產生適當的回壓,讓汽缸內混合氣能夠達到完全燃燒,故能有效提昇引擎扭力的輸出,令引擎性能發揮至最大功效。再者,由於渦流的擾動可吸收部份氣音。因此,本創作亦兼具有降低排氣噪音的效果。In use, when the exhaust gas discharged from the engine is introduced into the intake front pipe 10, the exhaust gas flows through the expansion gas chamber 12, and the gas undergoes a rapid expansion and diffusion change, thereby forming a gas vortex phenomenon (as shown in FIG. 2). By this, the vortex phenomenon can be used to increase the air pressure in the expansion chamber 12 to generate an appropriate back pressure, so that the mixture in the cylinder can achieve complete combustion, so that the output of the engine torque can be effectively improved, and the engine performance can be improved. Play to the fullest effect. Furthermore, some of the air sounds can be absorbed due to the disturbance of the eddy current. Therefore, this creation also has the effect of reducing exhaust noise.

In another embodiment of the present invention, in the embodiment, a partition 13 is further disposed in the expansion plenum 12 provided in the intake front pipe 10 so that The expansion chamber 12 is divided into two front and rear air chambers, and a plurality of air holes 14 for turbulent flow of gas are distributed on the partition plate 13, whereby the expansion air chamber 12 can be used to form a gas vortex into the exhaust gas. Phenomenon, and at the same time, due to the arrangement of the partition plate 13, the gas in the ventilating phenomenon is gradually passed through the air hole 14 in the partition plate, thereby blocking the time course of the air flow through the expansion air chamber 12, so that the gas pressure in the air chamber is further increased, that is, increased. The back pressure value in the exhaust pipe 1 allows the engine to generate higher torque values at low speeds.
