背景技术
通常,汽车通过气缸吸入与空气按适当比例混合的燃料并进行压缩之后,利用连杆和曲柄来将通过点火的膨胀发生的直线运动变换为具有扭矩的旋转运动,并借助上述驱动力行驶。
无论所喷射的燃料为汽油或柴油,上述汽车的引擎以能够使燃料顺畅地燃烧的方式通过过滤器净化从空气过滤器吸入的空气之后,使空气与喷射的燃料自然混合并通过气化器或喷射器进行喷射,从而获得可使汽车移动的动力。
因上述燃料的点火而发生的燃料气体通过引擎的排气歧管聚集在一个地方之后,在通过催化转化器的过程中,因一氧化碳和碳氢及氮化物等催化剂而被还原,在上述还原的状态下,通过管道向子消音器流入的燃烧气体通过具有多个隔膜的消音器并减少排出噪音,并向外部排出燃烧气体。
但是,如上所述,燃烧气体所通过的排气管简单呈圆形直管,从而,随着排出阻抗直接作用于排气管内部,很难期待燃烧气体的顺畅排出,由此导致输出阻抗和燃料比增大及引擎自身输出丧失等问题。
如上所述,在排气装置中,燃烧气体的顺畅排出力对如汽车的输出和引擎的燃油经济比等的汽车的性能产生极为重要的影响,以往排气装置的排气管呈简单直管形,由此,仅执行向外部引导从燃烧室排出的燃烧气体的作用,因此,为了提高引擎输出,只有需要倍加燃烧气体的排出力才能得到改善。
并且,向排气管的内部***弹簧形态的钢线来在排气管的内部引起回流现象,通过排气管内部的燃烧气体碰撞以紧贴于排气管内部面的状态***的钢线并借助弹簧回流,因此仅发生极为微弱的回流现象,通过线圈弹簧的中心部的燃烧气体在没有回流现象的情况下直接流动,且碰撞钢线回流流动和直接通过中心部的两个流动相互妨碍,由此,上述流速变得相当慢,且无法在排气管内部整体发生旺盛的回流现象,由此上述效果微不足道。
发明内容
(一)要解决的技术问题
对此,本发明的安装于以往汽车引擎的吸入配管或排气配管的流速增大装置解决如下问题,气体的回流流动不明确且不旺盛,从而导致燃料的混合及排气气体的排出不顺畅,且其安装并不简单。
(二)技术方案
即,本发明的引擎配管流速增大装置包括:内侧回流流动部,包括流速增大管体和回流引导槽,上述流速增大管体由具有弹力的板材弯曲成管体,以使内径以沿着气体的流动方向逐渐变窄,上述回流引导槽在流速增大管体的内部面弯曲而成,使得向上述流速增大管体的内部流入的空气回流流动,上述内侧回流流动部以等间距排列而成;气体流入引导部,使回流引导槽在向上述内侧回流流动部的气体流入部侧向气体流入部侧延伸形成,以便引导气体的回流流入并使回流引导长度极大化;外侧回流流动部,由在流速增大管体的外部面弯曲而成的回流引导槽形成,并以等间距排列而成,以便引导上述内侧回流流动部之间的未向流速增大管体的内部流入的气体在流速增大管体的外部面回流流动,引导上述外部面的空气从流速增大管体的气体流动排出方向的端部向中心部流动;离心回流引导切开部,在上述外侧回流流动部的气体流动方向的端部侧,使通过外侧回流流动部回流流动,并具有离心力的气体不以与内侧回流流动部的气体碰撞的方式以离心回流流动;以及管体结合板,切开上述气体流入引导部的端部的中央来向外侧弯曲,从而与安装配管的凸缘部啮合紧固。
(三)有益效果
因此,本发明包括内侧回流流动部,上述内侧回流流动部包括在流速增大管体的内部面弯曲而成的回流引导槽,以便能够使向流速增大管体内部流入的空气回流流动,上述内侧回流流动部以等间距排列而成,并包括气体流入引导部,使回流引导槽在上述内侧回流流动部的气体流入部侧向气体流入部侧延伸而成以便引导气体的回流流动并使回流引导长度极大化,由此,使气体明确并旺盛地向内侧回流流动部回流流动,并包括外侧回流流动部,上述外侧回流流动部由在流速增大管体的外部面弯曲成的回流引导槽形成,并以等间距排列形成,以便引导上述内侧回流流动部之间的未向流速增大管体内部流入的气体在流速增大管体的外部面回流流动,引导上述外部面的空气从气体流动排出方向的端部向中心部流动,由此,未向由放大缩小管形成的流速增大管体的内部流入的气体通过形成于内侧回流流动部之间的流速增大管体的外部面的外侧回流流动部回流流动来使气体的流动阻抗最小化,并使气体的回流流动在流速增大管体的内外面均匀且明确,并包括离心回流引导切开部,用于引导离心回流运动,以便在上述外侧回流流动部的气体流动方向的端部侧,使通过外侧回流流动部回流流动并具有离心力的气体以不与内侧回流流动部的气体碰撞的方式以离心回流流动,由此,通过内侧回流流动部流动的气体在沿着外侧回流流动部流动的气体的回流流动结束之前在外部离心回流流动,由此不会相互碰撞,从而,在没有气体的涡流损失的情况下,使气体的流动变得顺畅,并包括管体结合板,切开上述气体流入引导部的端部中央并向外侧弯曲,从而与安装配管的凸缘部啮合紧固,由此,可明确、简单并坚固地固定于需要安装的配管。

并且,若在上述内侧回流流动部10之间形成外侧回流流动部20,则未向由放大缩小管形成的流速增大管体100的内部流入的气体通过形成于内侧回流流动部10之间的流速增大管体100的外部面的外侧回流流动部20回流流动,由此使气体的流动阻抗最小化,并在流速增大管体100的内外面,使气体的回流流动均匀且明确。
并且,若在上述内侧回流流动部10形成离心回流引导切开部12,则通过内侧回流流动部10流动的气体在沿着外侧回流流动部20流动的气体的回流流动完成之前在外部离心回流流动,由此相互不会碰撞,从而,在没有气体的涡流损失的情况下,上述流动变得顺畅。
并且,本发明包括切开上述气体流入引导部11的端部的中央并向外部弯曲,从而使安装配管的凸缘部啮合紧固的管体结合板,由此,明确、简单且坚固地安装于需要安装的配管。
