Description

用于机车引擎上盖的套管 技术领域
本发明是关于一种套管， 尤指一种用于机车引擎上盖的进 /排气道中， 并可减少污垢卡附于进 /排气道内周壁的套管。 背景技术
传统机车引擎上盖设有进 /排气道， 让油气经由进气道进入引擎中， 再 由排气道排出，藉由火星塞点火驱动该机车引擎运作，进而提供该机车动力， 其中，油气进气量的多少与引擎的马力大小相关，即进气量正比于引擎马力， 故油气进气量越大时， 机车的速度则越高。
然而， 上述油气为空气与燃油混合均匀的混合体， 而一般进 /排气道内 周壁面呈现凹凸不平， 所以当油气通过该进 /排气道时， 会有部分燃油沾附 于该进 /排气道的内壁面上， 日积月累下来， 卡附于内壁面的燃油会影响该 进 /排气道的口径大小， 进而降低油气的进 /排气量， 使得机车引擎的运作 效率降低， 另一般机车引擎上盖铸造成形毛胚时， 毛胚成型过程会产生收缩 变形， 导致该机车引擎上盖的进 /排气道的内容积控制不易， 如以后续加工 处理改善更加困难。
另外， 一般赛车所用的机车， 为了提升机车速度， 会藉由加大进 /排气 道口径的方式， 提高油气进入引擎的进 /排气量， 因此传统机车引擎进 /排 气道口径一旦加大后就无法缩小， 所以在调整进 /排气量容积的多少及角度 上要非常小心也很不容易。 发明的公开
本发明的主要目的在于提供一种用于机车引擎上盖的套管，希藉此设计， 改善习用机车引擎上盖的进 /排气道容易卡附油垢的缺点， 以及该进 /排气 道口径一旦变大则无法缩小的缺点。
为达成前述目的， 本发明所设计的用于机车引擎上盖的套管， 其包含二 片体， 该二片体都具有一圆弧段及一外凸段， 且该圆弧段的一侧边形成一凹 部， 该二片体相对连接， 且其内侧壁面都为一光滑面。
由上述可以得知， 本发明套管是组设于机车引擎上盖的进 /排气道中， 自该外凸段伸入该进 /排气道中， 以该套管的光滑内侧壁面取代该进 /排气 道的凹凸不平内侧壁面， 可以降低燃油卡附的机会， 提高进气量的稳定度， 并且该套管内壁面所卡附的油垢量己达影响油气进 /排气量时， 使用者不需 拆卸引擎上盖， 只需将进 /排气口连接管道拆下， 直接更换该套管即可， 另 可藉由控制开外凸段的弯弧角度达到控制进 /排气道内容积的目的， 此外， 若是使用者为了增加进 /排气量而加大进 /排气道口径时， 可以藉由组设该 套管于该进 /排气道中， 进而缩小该进 /排气道口径， 所以不同管壁厚度的 套管可以控制该进 I排气道的进 I排气容量， 因此可以弥补机车在进 I排气 道的改装设计， 故本发明套管可以改善机车引擎上盖的进 /排气道在使用上 的缺点， 且适合产业上的利用。 附图的简要说明

图 2为本发明用于机车引擎上盖的套管套组于进 /排气道的第二较佳实 施例的立体分解示意图。

请参看图 1所示， 为本发明用于机车引擎上盖的套管的一较佳实施例， 该套管是组设于机车引擎上盖 20的进 /排气道 21中， 其包含有二片体 10， 该二片体 10相对连接形成一内部具有一容置空间的套管， 该二片体 10都包 括有一圆弧段 11及一外凸段 12，且该圆弧段 11一侧端连接该外凸段 12， 并 于该圆弧段 11的一侧边凹设一凹部 13，且该二片体 10的内壁面都为一光滑 面， 可以减少通过该二片体 10的油气卡附于内侧壁面上， 该二片体 10外侧 壁对应并可贴合于进 /排气道 21 )的内壁面，其中该二外凸段 1随进气道 21 的角度调整。
请参看图 2及图 3所示， 该二片体 10都于其圆弧段 13自由端处设有朝 该容置空间外凸伸的凸部 14， 藉由凸部 14的设计， 增加该二片体 10拆卸、 组合的方便性。
请参看图 4所示， 该二片体 10分别以其外凸段 12伸入进 /排气道 21 的开口处，且该二片体 10的凸部 14卡抵于该进 /排气道 21开口处的侧面上, 凸出于该进 /排气道 21的侧面， 此时凸部 14兼具垫圈的功能。
又参看图 5所示， 该进 I排气道 21的开口处设有组接部 22并对应于该 二片体 10的凸部 14， 因此该管体 10伸入该进 I排气道 21时， 其凸部 14可 卡抵组接于该进 /排气道 21的组接部 22中，使得组设后的凸部 14不凸出于 该进 I排气道 21开口处的侧面。
使用者可以将本发明套管组设于机车引擎上盖 20的进 /排气道 21中， 自该外凸段 12处伸入该进 I排气道 21，并该套管的二片体 10可以为冲压成 型的构件， 且组设入该进 /排气道 21 时， 其外侧壁面贴合于该进 /排气道 21的内壁面， 若使用者在改装进 /排气道 21的口径后， 可以组设适合的套 管于进 /排气道 21中， 使得该进 /排气道 21回复至原来的口径， 或是可以 进一步缩小该进 I排气道 21口径，进而依使用者的需求来控制油气的进 I排
工业应用性
综上所述， 经由上述结构特征、 技术内容及操作使用上的详细说明， 可 清楚看出本发明设计特点在于： 本发明套管藉由该二片体内侧光滑壁面取代 该进 /排气道内侧的凹凸不平壁面， 使得通过套管的油气不容易沾附油污于 该套管上， 因此该进气量比较不会受到影响， 故可以维持稳定的进气量； 另 已加大口径的进 /排气道可以藉由组设本创作而进一步縮小其口径， 使进 / 排气量减少至所需的量， 故本发明用于机车引擎上盖的套管可以有效改善燃 油卡附于进 /排气道内侧壁的问题， 并可以改变进 /排气道口径大小以控制 油气的进气量， 使得进 /排气道的设计更具有灵活性； 另本创作套管的外凸 段的弯弧角度是可控制的， 因此可藉由外凸段达到有效控制进 /排气道内容 积的功用， 所以本发明套管有助于产业上的利用。
