Abstract
Description
本創作係涉及一種汽車排氣管,尤指一種可改變排氣音量的排氣管。This creative department relates to an automobile exhaust pipe, especially an exhaust pipe which can change the exhaust volume.
擁有汽車一直是許多人的夢想,車輛改裝也是眾多的玩車人為了符合自己的個性或是為了創造出心中理想中的愛駒的一個手段,而在車輛改裝的項目中,改裝排氣管一直以來都是相對熱門的選項。為了在可以享受排氣管聲浪的情況下也同時做好噪音控管,許多人會在排氣管加裝變聲裝置(真空、電子閥門),使排氣管可以在郊區增加音量發出足夠響度的聲浪,而在市區則可以維持原本的低音量以確保不會造成他人困擾。Owning a car has always been the dream of many people. Vehicle modification is also a means for many gamers to meet their personalities or to create the ideal love horse in their hearts. In the project of vehicle modification, the modification of the exhaust pipe has always been It has been a relatively popular option since. In order to control the noise at the same time while enjoying the sound waves of the exhaust pipe, many people will install a sound changing device (vacuum, electronic valve) on the exhaust pipe, so that the exhaust pipe can increase the volume in the suburbs and emit enough loudness. Sound waves, while in the urban area can maintain the original low volume to ensure that it will not cause trouble to others.
請參閱圖9及圖10所示,現有技術中以變聲裝置(真空、電子閥門)改變排氣管音量的原理如下,首先一般的排氣管裝設有一消音器91,使氣體在通過時會先降低整體排器音量再流向外界;而增加排氣音量的方式,則是增加一條沒有流經消音器91的直通管92並使其直接連通引擎及外界,且以一三通管93來連通消音器91及直通管92,並且在直通管92與三通管93之間設置一閥門94來控制直通管92的流通與否,藉此當閥門94關閉時,氣體會因無法通過三通管93其中一端上的閥門94,所以轉向由另一端流向消音器91且被消音以維持原本的低排氣音量(如圖9所示);而當閥門94開啟時,氣體則直接通過閥門94並由直通管92排出並保有引擎原本的排氣音量,也就是相對的增加排氣音量(如圖10所示)。Please refer to FIGS. 9 and 10. In the prior art, the principle of changing the volume of the exhaust pipe with a sound changing device (vacuum, electronic valve) is as follows. First, the general exhaust pipe is equipped with a
然而,由於三通管93本身的結構,使得氣體在經過三通管93時不論流向為何,三通管93都會在氣體流向的側邊形成一個橫向空間,而該橫向空間對於流動的氣體則會形成一個亥姆霍茲共振腔,並且因為亥姆霍茲原理而使得在直通管92內流動的氣體的音量降低,所以即便是沒有流經消音器91,整體的排氣音量相較於引擎原本的排氣音量還是會有明顯的降低,也就是說三通管93的結構本身就會造成消音的效果,所以即便是藉由直通管92連通引擎直接排出至外界,但是相對於流經消音器91的排氣音量來說,整體音量提升的幅度較不理想,於是現有技術中的可改變音量的排氣管確實有待改良。However, due to the structure of the three-
此外,閥門94的轉軸係設於管路的正中央,這樣的設計也會阻擋氣流而進一步使排氣音量降低。In addition, the rotating shaft of the
有鑑於前述之現有技術的缺點及不足,本創作提供一種可變音量排氣管,其可克服亥姆霍茲共振腔所帶來的消音效果,使整體的排氣音量更進一步提升。In view of the aforementioned shortcomings and deficiencies of the prior art, this creation provides a variable volume exhaust pipe, which can overcome the silencing effect brought by the Helmholtz resonant cavity, and further improve the overall exhaust volume.
為達到上述的創作目的,本創作所採用的技術手段為設計一種可變音量排氣管,其中包含: 一交會空間; 一引擎管,其連接於該汽車引擎,且延伸至該交會空間; 一直通管,其連通至外界,且延伸至該交會空間; 一消音管,其延伸至該交會空間; 一三通閥,其位於該交會空間,且連接該引擎管、該直通管及該消音管,且該三通閥選擇性地使該引擎管連通該直通管及該消音管的其中之一,並同時封閉另一者; 一消音器,其連接該消音管,且該消音管藉由該消音器連通至外界。In order to achieve the above-mentioned creative purpose, the technical means adopted in this creation is to design a variable volume exhaust pipe, which includes: a meeting space; an engine pipe, which is connected to the car engine and extends to the meeting space; has been A through pipe, which communicates with the outside world and extends to the intersection space; a muffler pipe, which extends to the intersection space; and a three-way valve, which is located in the intersection space and connects the engine pipe, the straight pipe, and the muffler pipe , And the three-way valve selectively connects the engine pipe to one of the straight pipe and the muffler pipe, and at the same time closes the other; a muffler, which is connected to the muffler pipe, and the muffler pipe passes the The silencer communicates with the outside world.
本創作的優點在於,藉由在引擎管、直通管及消音管三者的交界處設置三通閥,並以三通閥選擇性的封閉連通於直通管的出口端或是連通於消音管的出口端,藉此即可以三通閥控制氣體是否流經消音器,進而改變排氣音量的大小;並且,在三通閥在開啟連通於直通管的出口端以增加排氣音量的同時,三通閥也會一併封閉連通於消音管的出口端,以避免如現有技術般於氣體流向的側邊形成一個橫向空間,本創作藉此在氣體流動的路徑上便不會因為三通管的結構而形成亥姆霍茲共振腔,進而可以克服亥姆霍茲原理所帶來的消音效果,使整體的排氣音量更進一步提升。The advantage of this creation is that by installing a three-way valve at the junction of the engine pipe, the straight pipe and the muffler pipe, and selectively closing the outlet port of the straight pipe or the muffler pipe with the three-way valve The outlet end, by which the three-way valve can control whether the gas flows through the silencer, thereby changing the size of the exhaust volume; and, while the three-way valve opens the outlet end connected to the straight pipe to increase the exhaust volume, the three The through valve will also close the outlet end of the muffler tube to avoid forming a lateral space on the side of the gas flow as in the prior art. This creation will not cause the gas to flow on the path of the three-way tube. The structure forms a Helmholtz resonant cavity, which can overcome the silencing effect brought by the Helmholtz principle and further increase the overall exhaust volume.

請參閱圖1所示,本創作之可變音量排氣管裝設於一汽車引擎A且包含有一交會空間10、一引擎管20、一直通管30、一消音管40、一三通閥50及一消音器60。Please refer to FIG. 1, the variable volume exhaust pipe of this creation is installed in a car engine A and includes an
引擎管20連接於汽車引擎A,且延伸至交會空間10;直通管30連通至外界,且延伸至交會空間10;消音管40連通至消音器60並藉由消音器60連通至外界,且消音管40延伸至交會空間10;也就是說,氣體由汽車引擎A排放至引擎管20後有兩種排氣路徑可以選擇,一種是流經連通至消音器60的消音管40並且被消音後再排放至外界;另一種則是流經直通管30且不經過消音即排放至外界;而引擎管20與兩種排氣路徑(也就是直通管30及消音管40)三者之間形成有一交會空間10。The
三通閥50位於交會空間10,且連接引擎管20、直通管30及消音管40,且三通閥50選擇性地使引擎管20連通直通管30及消音管40的其中之一,並同時封閉另一者;也就是說,引擎管20與兩種排氣路徑(也就是直通管30及消音管40)三者在延伸至交會空間10後皆連接至三通閥50,而三通閥50可以選擇引擎管20要連通至直通管30還是消音管40,並且使引擎管20在連通至直通管30的同時封閉引擎管20與消音管40之間的連通口,或是在使引擎管20在連通至消音管40的同時封閉引擎管20與直通管30之間的連通口。The three-

請參閱圖1、圖5及圖6所示,本創作在使用時經由外部裝置控制三通閥50的驅動元件53藉以使閥門52相對於三通管51轉動,並且以閥門52在選擇開啟其中一出口端512的同時關閉另一開口端512,藉此當想要低排氣音量時可以閥門52關閉三通閥50與直通管30的連通處,如此一來引擎排氣就會經由三通閥50流向消音管40並通過消音器60且被消音後再排放至外界;反之,若想要高排氣音量時,則以閥門52關閉三通閥50與消音管40的連通處,如此一來引擎排氣就會經由三通管50流向直通管30並且不經過任何消音處理直接排放至外界,並且,此時由於閥門52關閉了三通閥50與消音管40的連通處,所以三通管51在引擎氣體流向的側邊就不會形成有橫向空間,所以對於流動的氣體也不會形成亥姆霍茲共振腔,如此一來就可以克服亥姆霍茲原理所帶來的消音效果,使整體的排氣音量更進一步提升。Please refer to FIG. 1, FIG. 5 and FIG. 6, when the author uses the
