style="text-indent:25px">在實(shí)際的工作中，天津博世雙鉑金火花塞套裝，火花塞還是有一定損耗的，也有一定的使用壽命。導(dǎo)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?xì)饧訜嵋约?0~60°C的進(jìn)氣冷卻，還要受到高達(dá)3~5MPa周期性氣體壓力的沖擊，這樣會導(dǎo)致火花塞產(chǎn)生機(jī)械疲勞，進(jìn)而導(dǎo)致機(jī)械強(qiáng)度以及絕緣性能的下降，嚴(yán)重時甚至?xí)?dǎo)致火花塞破裂、斷裂，因此必須在火花塞機(jī)械強(qiáng)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(dá)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(dāng)火花塞上出現(xiàn)油性沉積物時，就表明潤滑油已進(jìn)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，天津博世雙鉑金火花塞套裝，天津博世雙鉑金火花塞套裝。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(jìn)一步分析車子哪里出現(xiàn)問題了。單鉑金火花塞指的是中心電極帶有鉑金材質(zhì)的火花塞。天津博世雙鉑金火花塞套裝</p><div

style="text-indent:25px">火花塞的作用及工作原理火花塞是汽油發(fā)動機(jī)上極為重要的一個零部件，它的作用是把高壓線圈和高壓導(dǎo)線送來的脈沖高壓電放電，擊穿火花塞兩電極間空氣，產(chǎn)生電火花引燃?xì)飧變?nèi)的混合氣體，使其燃燒膨脹做功。它是由電極、螺紋以及絕緣體這三部分組成的一個不可分解的整體，一般都安裝的氣缸蓋上，電極部分伸入到燃燒室中點(diǎn)火做功。一般汽油發(fā)動機(jī)都是每缸有一個火花塞，個別發(fā)動機(jī)上安裝兩個火花塞（比如飛度）。由于火花塞直接影響發(fā)動機(jī)的燃燒狀態(tài)，所以人們把它比作發(fā)動機(jī)的心臟。天津博世雙鉑金火花塞套裝劣質(zhì)汽油或者添加劑也會導(dǎo)致火花塞陶瓷體的污損。</p><div

style="text-indent:25px">如何更換火花塞？大家在修理廠看修理工換火花塞非常快，就以為這是一項非常簡單的作業(yè)。事實(shí)并非如此，換火花塞是非常有技術(shù)含量的。姑且不說有些車型的火花塞非常隱蔽，非專業(yè)人士都找不到，并且拆卸難度極高，換幾個火花塞用小半天的時間也是正常的。就是非常直觀可見的火花塞，更換也不是那么容易的。現(xiàn)在隨著發(fā)動機(jī)技術(shù)的不斷提高，結(jié)構(gòu)也越來越復(fù)雜，拆卸火花塞的流程也就非常麻煩，通常都要拆卸進(jìn)氣歧管后才能拆卸火花塞。還有就是有些車型的火花塞的形狀變得越來越細(xì)，越來越長，對安裝扭矩的要求也非常高。還有就是有些車型火花塞與氣缸位置不是垂直的，需要萬向扳手拆能拆卸，如果用扳手垂直旋轉(zhuǎn)則會導(dǎo)致受力偏差，陶瓷體出現(xiàn)破裂。</p><p style="text-indent:25px">火花塞熱值，通俗的表達(dá)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?dāng)?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(jī)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(yán)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(jī)適合的火花塞熱值。奧迪發(fā)動機(jī)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。</p><div

style="text-indent:25px">判斷火花塞是否應(yīng)該更換還可以利用設(shè)備進(jìn)行檢測，用示波器觀察點(diǎn)火系統(tǒng)工作情況，查看各氣缸火花塞點(diǎn)火電壓數(shù)值。如果各氣缸點(diǎn)火電壓高度一致，點(diǎn)火震蕩曲線一致，并且都在標(biāo)準(zhǔn)范圍內(nèi)，說明火花塞技術(shù)狀況良好，不需要更換；如果各氣缸點(diǎn)火電壓不均，或者點(diǎn)火曲線形狀不同，說明點(diǎn)火系統(tǒng)有故障，此時就需要檢查火花塞，如果接近更換周期直接更換。至于說如何選擇與更換火花塞，選擇什么品牌和級別的火花塞？簡單直白的方法就是先看原車火花塞型號和品牌，如果原車火花塞級別比較低還可以選擇升級款的型號來提升點(diǎn)火性能?；鸹ㄈ霈F(xiàn)電暈痕跡后并非是漏氣，對火花塞性能沒有影響。福建NGK雙鉑金火花塞店鋪</p><p
