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?？量痰?，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，河南路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞經(jīng)銷商、溫度高，火花塞要承受巨大的壓力沖擊和溫度變化，河南路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞經(jīng)銷商，這就對它的機械強度提出了很高的要求；此外，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，河南路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞經(jīng)銷商，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，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。根據(jù)車主手冊上規(guī)定的保養(yǎng)周期進行更換火花塞。河南路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞經(jīng)銷商</p><div

style="text-indent:25px">針對針雙銥金火花塞：市面上在售的火花塞中針對針結(jié)構(gòu)雙銥金火花塞屬于綜合性能比較好的一款了，其中心電極和側(cè)電極都采用了銥金材質(zhì)，而且側(cè)電極采用了突出設(shè)計，側(cè)電極則做的非常細，這樣就能更好的達到電極頂部放電的效果，而且針對針的結(jié)構(gòu)給火焰核留有的空間很大，更利于火花的行成，因此這種火花塞點火性能非常好，部分增壓發(fā)動機的車型都開始大量的配備此種火花塞，其正常壽命可以達到10萬公里，價格隨之也更高，通常在100元以上，還有一點就是現(xiàn)在缸內(nèi)直噴技術(shù)的應(yīng)用對火花塞的損耗比較大，匹配缸內(nèi)直噴技術(shù)的車型工廠建議的更換里程通常為4-6萬。北京摩托車火花塞商家推薦單銥金火花塞使用壽命為4-5萬公里。</p><div

style="text-indent:25px">火花塞熱值，通俗的表達就是火花塞裙體（包裹中心電極的部位）的溫度大小，一般都是用阿拉伯數(shù)字表示。例如：博世編號F8DCOR中的數(shù)字8，要特別說明的是這個“8”不是指8度，而是指用“8”表示的一個溫度范圍值。由于汽油在發(fā)動機中不可能完全燃燒，會有少量的碳粉沉積，這些碳粉會沉積在火花塞的中心電極和側(cè)電極上，積累到一定程度會嚴重影響火花塞的正常工作。但如果火花塞上的溫度足夠高，這些碳粉就會自己燃燒了，我們把這個碳粉自己燃燒的溫度范圍就稱為該款發(fā)動機適合的火花塞熱值。</p><p style="text-indent:25px">在實際的工作中，火花塞還是有一定損耗的，也有一定的使用壽命。導致火花塞損耗主要有以下幾個因素： 1、火花塞的工作條件非常惡劣，它要周期性的受到1500~3000°C高溫燃氣加熱以及50~60°C的進氣冷卻，還要受到高達3~5MPa周期性氣體壓力的沖擊，這樣會導致火花塞產(chǎn)生機械疲勞，進而導致機械強度以及絕緣性能的下降，嚴重時甚至會導致火花塞破裂、斷裂，因此必須在火花塞機械強度下降到允許使用的程度之前，將其更換掉；然而不少車主的火花塞常常出現(xiàn)這樣那樣的問題，達不到其正常使用壽命。那么，你又是否知道為什么火花塞這么容易壞呢?情況一：當火花塞上出現(xiàn)油性沉積物時，就表明潤滑油已進入燃燒室內(nèi)。情況二：火花塞電極和內(nèi)部有黑色煤煙層，通常表明氣缸內(nèi)混合氣體過濃?；鸹ㄈ薀g狀態(tài)：火花塞頂端有燒蝕或是破壞、電極出現(xiàn)熔化、燒蝕現(xiàn)象都表明火花塞已經(jīng)毀壞。所以，在更換過程中，車主可以檢查火花塞燒蝕的癥象以及顏色的變化，從而進一步分析車子哪里出現(xiàn)問題了。熱值越低，表示火花塞的吸熱與散熱平衡能力越差。</p><div

style="text-indent:25px">普通火花塞的壽命為2萬公里，鉑金火花塞壽命約4萬公里，而銥金火花塞的壽命則能達到6至8萬公里。隨著現(xiàn)在直噴發(fā)動機的普及，車主在享受高效燃燒的同時，也意識到了發(fā)動機運轉(zhuǎn)對于汽油標號、機油和火花塞要求的提高。為了保持良好的燃燒，火花塞的更換周期明顯要比自然吸氣發(fā)動機縮短，普遍要求20000公里時就進行更換。發(fā)動機的運轉(zhuǎn)過程中，氣缸內(nèi)的工作是非常劇烈的，火花塞是燃燒過程中非常重要的一個部件。進入氣缸內(nèi)部的空氣，在被活塞高度壓縮后，只有在噴油嘴噴油和火花塞點火之后才能燃燒，繼而產(chǎn)生動力。火花塞的每次點火都會有上萬伏的電壓擊穿兩極之間的氣體，產(chǎn)生電弧，點燃混合氣。有電弧產(chǎn)生就會消耗火花塞兩極的金屬，火花塞兩極之間的距離是有極限的，超過了極限距離的火花塞就必須要更換;再一個就是火花塞的中心極是有白金層的，一旦這個金屬層消耗殆盡，也是要更換的，不然會導致點火不良導致油耗增大、動力表現(xiàn)衰弱。電裝的火花塞，它是以數(shù)字9~35來表示熱值。北京摩托車火花塞商家推薦</p><p

style="text-indent:25px">燃燒過熱的火花塞絕緣體裙端呈灼白狀，電極過早燒蝕。產(chǎn)生此狀的原因是，點火時間過早，燃油噴射過晚，導致的冷卻條件差；還有的可能是使用了低辛烷值汽油、混合氣太稀、火花塞不匹配點火位置在缸內(nèi)微長、以及火花塞的熱值過高、火花塞未正確安裝導致無法正常散熱、發(fā)動機冷卻系統(tǒng)故障造成發(fā)動機異常高溫等原因。解決辦法就火花塞而言，更換熱值較低的火花塞。錳鉛中毒的火花塞：絕緣體裙體和電極被燒熔。導致的原因是汽油中添加了含有錳、鉛等元素的高熔點氧化物。當汽車連續(xù)高速行駛，這些錳鉛氧化物不會被火花塞裙體的溫度分解排出缸內(nèi)，而是會沉積在火花塞上，由于錳鉛等氧化物的熱導性差，燃油不能使其降低溫度，而汽車的連續(xù)高速行駛使這些氧化物匯聚能量，溫度遠遠超出火花塞電極材料的熔點，使火花塞的電極熔化而失效，常出現(xiàn)于高速長途后，這種現(xiàn)象不屬于火花塞的質(zhì)量問題，應(yīng)教育車主避免隨意添加劣質(zhì)汽油添加劑。河南路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞經(jīng)銷商</p><p
