id="z7htbzx" class="box"><p><p style="text-indent:25px">至于火花塞更換周期也有比較特殊的情況，那就是奧迪汽車的火花塞更換周期只有短短的兩萬公里。這個更換周期是所有車型中屬于非常短的，它使用鉑金、銥金類的火花塞，但是使用壽命卻比銅鎳火花塞都要短，這究竟是為什么呢？這主要是因為，奧迪發(fā)動機的工作條件是非常苛刻的，它使用的是渦輪增壓缸內(nèi)直噴發(fā)動機，做功時氣缸內(nèi)壓力大，遼寧德國進口貴金屬火花塞質(zhì)量、溫度高，火花塞要承受巨大的壓力沖擊和溫度變化，這就對它的機械強度提出了很高的要求；此外，遼寧德國進口貴金屬火花塞質(zhì)量，奧迪的火花塞每一個工作循環(huán)點火兩次，而不合適一次，這樣兩萬公里就相當(dāng)于其他車型的四萬公里；還有就是奧迪發(fā)動機采用分層燃燒技術(shù)，在火花塞附近可燃混合氣濃度高、、燃燒快，對火花塞的損耗也就更大。車企實驗發(fā)現(xiàn)，火花塞在兩萬公里之后性能就出現(xiàn)了下降，因此，遼寧德國進口貴金屬火花塞質(zhì)量，為了保證奧迪發(fā)動機性能的穩(wěn)定可靠、動力充分發(fā)揮，就規(guī)定兩萬公里更換火花塞?，F(xiàn)在有很多奧迪4s店規(guī)定，如果兩萬公里不更換火花塞，視為自動脫保。雙鉑金火花塞是指火花塞的中心電極和側(cè)電極都采用了鉑金材質(zhì)。遼寧德國進口貴金屬火花塞質(zhì)量</p><div

style="text-indent:25px">如果我們能把火花塞拆下來，那就更容易判斷了?；鸹ㄈ恼顟B(tài)是：電極部分呈灰白色，灰黃色或淺棕色，電極間隙大約在0.8~1.1mm之間。如果拆下來的火花塞上面沾滿了油污，或者電極燒蝕嚴(yán)重、間隙過大、腐蝕變形、雜質(zhì)沉積等，或者絕緣體破損等，這樣的火花塞就需要更換了。不過如果火花塞上只是積碳較多，但電極沒有問題，這樣的火花塞是可以清洗后繼續(xù)使用的。還有一種是火花塞上面有一圈電暈，很多修理工說它是漏氣了，必須換火花塞，但事實并非如此，它是由于高壓電與機油分子共同作用產(chǎn)生的，對火花塞的性能沒有任何影響。天津博世雙鉑金火花塞性能根據(jù)車主手冊上規(guī)定的保養(yǎng)周期進行更換火花塞。</p><div

style="text-indent:25px">如何判斷火花塞是否需要更換？由于發(fā)動機燃燒室內(nèi)部的環(huán)境是非常惡劣的，高溫、高壓并且冷熱變化劇烈，火花塞在使用中會發(fā)生比如電極間隙增大、絕緣體絕緣強度下降等變化，所以它的點火性能會逐漸的下降，嚴(yán)重時甚至不能點火，這樣它就會對發(fā)動機性能造成很大的影響，此時的火花塞就需要更換了。一般汽車廠家都規(guī)定了一個建議的更換周期，大致在3~5萬公里之間，有些高性能的火花塞可以使用十萬公里以上，這就看廠家的具體規(guī)定了。但是并不是說火花塞到了規(guī)定的更換周期就不能用了，火花塞的性能衰減有一個過程，并不是突然就不行了。有些火花塞即使過了更換周期，發(fā)動機的性能還是沒有什么變化，這樣的火花塞也是可以繼續(xù)使用的；但也有些車型使用很短的時間，火花塞就不行了。</p><p style="text-indent:25px">隨著汽車的配置越來越高，對發(fā)動機輸出功率、火花塞的點火要求也越來越高，為提高火花塞的點火效率，設(shè)計者都選擇了大幅提高點火電壓的辦法火花塞的各種參數(shù)對點火性能尤為重要，曾經(jīng)的普通小方火花塞全部通用的時代已經(jīng)過去，從收集的市場反饋信息可以看出，還存在著很大一部分修理廠在車輛維修時對火花塞應(yīng)用與安裝技術(shù)沒有足夠的重視，更換火花塞后時常發(fā)生汽車發(fā)動機抖動、冒黑煙、動力不足、漏電、甚至有火花塞斷裂導(dǎo)致拉缸或頂缸現(xiàn)象，既使車主抱怨連天，又使自己搭料搭工還失去了客戶的信任。只有更深地了解火花塞各種參數(shù)表示的含義，才能幫助您做出正確判斷，減少火花塞引起的故障發(fā)生。雙銥金火花塞只指火花塞的中心電極和側(cè)電極都采用了貴金屬銥金材料。</p><div

style="text-indent:25px">一般功率高、壓縮比大的發(fā)動機選用熱值高的冷型火花塞；相反，功率低、壓縮比小的發(fā)動機選用熱值低的熱型火花塞；一般的家用轎車大多使用中等熱值的火花塞。不過，現(xiàn)在的很多發(fā)動機都采用了渦輪增壓、缸內(nèi)直噴、可變氣門正時與升程甚至可變壓縮比等新技術(shù)，所以火花塞的選用也不是完全遵循這樣的規(guī)律。一般汽車工程師會經(jīng)過嚴(yán)格的計算與實驗，才能確定火花塞的型號與熱值，所以我們在更換火花塞時必須選擇與原車熱值一樣的火花塞，不允許更改。更換火花塞時必須有**的工具，并且要正確使用。遼寧德國進口貴金屬火花塞質(zhì)量</p><p
