氣門挺桿簡介

氣門挺桿。氣門挺桿的作用如下：

1、為了保證氣門關閉嚴密，會在氣門桿端與氣門驅動件之間留有適當的間隙，稱為氣門間隙；

2、若氣門間隙調整不當就會使發動機運行不正常的，過大會影響氣門的開啟量，氣門升程減少引起進氣不足，排氣不徹底，過小會引起氣門關閉不嚴引起漏氣，造成動力下降；

3、所以為了避免氣門間隙調整不當引起的麻煩，一般高速發動機上都會使用可自行調整氣門間隙的液力挺桿。

汽車(che)的(de)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)相當于汽車(che)的(de)(de)心臟。發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)故(gu)障也(ye)是困擾車(che)友的(de)(de)問題(ti)，氣(qi)(qi)(qi)(qi)(qi)門(men)(men)挺(ting)(ting)(ting)桿(gan)(gan)(gan)是發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)的(de)(de)重要(yao)部件。接下來(lai)就讓典邦給大(da)家(jia)介紹(shao)一下氣(qi)(qi)(qi)(qi)(qi)門(men)(men)挺(ting)(ting)(ting)桿(gan)(gan)(gan)的(de)(de)作用(yong)吧！氣(qi)(qi)(qi)(qi)(qi)門(men)(men)挺(ting)(ting)(ting)桿(gan)(gan)(gan)的(de)(de)功能，氣(qi)(qi)(qi)(qi)(qi)門(men)(men)挺(ting)(ting)(ting)桿(gan)(gan)(gan)簡介-功能也(ye)是用(yong)于推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)(qi)(qi)門(men)(men)打開(kai)(kai)的(de)(de)裝置(zhi)(zhi)。因為(wei)早(zao)期發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)中使用(yong)的(de)(de)這種(zhong)裝置(zhi)(zhi)形(xing)狀像一根細桿(gan)(gan)(gan)，所以(yi)被(bei)稱(cheng)為(wei)氣(qi)(qi)(qi)(qi)(qi)門(men)(men)挺(ting)(ting)(ting)桿(gan)(gan)(gan)。它(ta)的(de)(de)主要(yao)功能是將凸輪的(de)(de)旋轉運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉化為(wei)往復運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。但(dan)這種(zhong)結構的(de)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)凸輪軸一般(ban)不布(bu)置(zhi)(zhi)在(zai)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)頂(ding)(ding)部。隨著現代(dai)汽車(che)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)技術的(de)(de)發(fa)(fa)展，越來(lai)越多的(de)(de)汽車(che)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)采用(yong)頂(ding)(ding)置(zhi)(zhi)凸輪軸結構，其中傳統的(de)(de)長氣(qi)(qi)(qi)(qi)(qi)門(men)(men)挺(ting)(ting)(ting)柱(zhu)(zhu)基本取(qu)消，取(qu)而代(dai)之的(de)(de)是由凸輪軸驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)更加(jia)緊湊的(de)(de)液(ye)(ye)壓(ya)挺(ting)(ting)(ting)柱(zhu)(zhu)，或者凸輪軸直接驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)(qi)(qi)門(men)(men)搖(yao)臂來(lai)控制氣(qi)(qi)(qi)(qi)(qi)門(men)(men)的(de)(de)開(kai)(kai)閉。液(ye)(ye)壓(ya)杠(gang)桿(gan)(gan)(gan)主要(yao)由柱(zhu)(zhu)塞、單向(xiang)閥(fa)(fa)和單向(xiang)閥(fa)(fa)彈(dan)(dan)簧組(zu)成(cheng)(cheng)。液(ye)(ye)壓(ya)桿(gan)(gan)(gan)始終與凸輪軸接觸，并且無間隙(xi)運行。在(zai)挺(ting)(ting)(ting)桿(gan)(gan)(gan)內部，液(ye)(ye)壓(ya)用(yong)于調(diao)整間隙(xi)。液(ye)(ye)壓(ya)挺(ting)(ting)(ting)柱(zhu)(zhu)主要(yao)由柱(zhu)(zhu)塞、單向(xiang)閥(fa)(fa)和單向(xiang)閥(fa)(fa)彈(dan)(dan)簧組(zu)成(cheng)(cheng)。止回閥(fa)(fa)用(yong)于儲存或釋放油。通過改變挺(ting)(ting)(ting)柱(zhu)(zhu)腔內的(de)(de)油壓(ya)，可(ke)以(yi)改變液(ye)(ye)壓(ya)挺(ting)(ting)(ting)柱(zhu)(zhu)的(de)(de)工(gong)作長度，從(cong)而自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)調(diao)整氣(qi)(qi)(qi)(qi)(qi)門(men)(men)間隙(xi)。

雪鐵龍C3簡介

據(ju)了解，雪(xue)鐵龍(long)C3是(shi)一款(kuan)小型轎車(che)(che)，它(ta)的原型車(che)(che)是(shi)1998年(nian)巴黎車(che)(che)展的雪(xue)鐵龍(long)C3概(gai)念車(che)(che)，在C3的外型和大眾的甲殼蟲很有(you)點相似，車(che)(che)身非常圓潤。C3的外型的設(she)計(ji)風(feng)格延續(xu)了法國的浪漫和前衛風(feng)格，式(shi)樣非常新穎，有(you)個性，
