style="text-indent:25px">L型：較常見的氣缸布局形式目前，應(yīng)用較普遍的發(fā)動機氣缸布局是L型。尤其是在2.5L以下排量的發(fā)動機上。那么L型發(fā)動機是什么樣的結(jié)構(gòu)呢？一汽大眾高級工程師洪治平告訴記者：“顧名思義，L型布局的發(fā)動機所有氣缸均是按同一角度并排成一個平面，并且只使用了一個氣缸蓋，同時其缸體和曲軸的結(jié)構(gòu)也要相對簡單。具體來說，我們常見的大致有L3、L4、L5、L6型四款。這種布局發(fā)動機的優(yōu)勢在于尺寸緊湊，穩(wěn)定性高，低速扭矩特性好并且燃料消耗也較少，當然也意味著制造成本更低。此外，L型氣缸布局的發(fā)動機體積也比較緊湊，可以適應(yīng)更靈活的布局，也更加方便于布置增壓器類的裝置。其主要缺點在于發(fā)動機本身的功率較低，并不適合配備6缸以上的車型?！?/p><p style="text-indent:25px">壓縮系漏氣：由于磨損損壞、松動和錯位，使構(gòu)成壓縮系的零件間出現(xiàn)不應(yīng)有的間隙，不起密封作用，導(dǎo)致氣缸內(nèi)的空氣在壓縮過程中泄漏。（1）氣缸墊漏氣氣缸墊邊緣漏氣，致使壓縮和作功的行程時有氣體竄出。產(chǎn)生氣缸墊漏氣的原因有：氣缸蓋固定螺栓預(yù)緊力不足，或沒有按要求的擰緊順序分次均勻的擰緊；氣缸蓋和氣缸體接合平面翹曲；氣缸套凸出高度不夠，或相鄰兩缸凸出高度差過大，柴油機工作溫度過高而燒壞氣缸墊；壓縮比過高，使爆發(fā)壓力過大。（2）活塞環(huán)漏氣可在氣缸內(nèi)注入一些干凈的機油，若經(jīng)檢查氣缸壓力明顯提高，則說明活塞環(huán)密封不嚴，否則，說明氣缸壓力與活塞環(huán)無關(guān)，另外，還可以觀察柴油機工作時從加機油口排出的廢氣量多少來判斷。產(chǎn)生活塞環(huán)漏氣的原因：活塞、活塞環(huán)、氣缸磨損嚴重，配合間隙過大，活塞環(huán)彈力不足，折斷或被積炭卡死在環(huán)槽里不能活動，活塞環(huán)端間隙和邊間隙過大。當檢測值高于規(guī)定值10％以上時，表明氣缸內(nèi)可能有積水、積油，或燃燒室內(nèi)積碳過多。</p><div
