style="text-indent:25px">火花塞電極間隙就是指側(cè)電極和中心電極之間的距離。不同發(fā)動機需要的間隙不同，汽車火花塞間隙從0.6mm到1.6mm不等，具體是由點火線圈產(chǎn)生的高壓冗余量決定的。一般情況下，間隙越大，電弧越長，點火能量就越大。但如果超出了點火線圈產(chǎn)生的冗余量，就事得其反，不僅不能提高火花塞的點火能量，反而由于電壓不足，造成火花塞丟火，同時，點火線圈由于長時間處于超負荷運行，造成點火線圈負荷過大而發(fā)熱，使內(nèi)部短路或斷路損壞，大部分的點火線圈設(shè)計壽命是30萬公里以上，不正確使用火花塞，使得其提前退休，是很多修理廠點火線圈退貨多的主要原因。但火花塞間隙過小也不好，不能充分施放高壓電，點燃混合氣的熱量不夠，造成不完全燃燒，使發(fā)動機的動力不能充分釋放。在正常情況下，火花塞的壽命就是由火花塞的間隙決定的，過大間隙需要的擊穿電壓過大，點火線圈電壓冗余量不夠，反而會使點火不充分。</p><p 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(biāo)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(dǎo)致點火不良導(dǎo)致油耗增大、動力表現(xiàn)衰弱。火花塞電極還會受到汽油和機油的污染。</p><div

NGK火花塞給混合氣點火，具有打火機的作用。為起打火機的作用，火花塞要在非常苛刻的條件下工作。發(fā)動機的點火流程：發(fā)動機吸入空氣與汽油混合-混合氣體壓縮-火花塞點燃混合氣體-混合氣體爆發(fā)能量轉(zhuǎn)化成動能，期間火花塞承受的電壓可以達到20000v-30000v，電極材料還要承受混合氣體燃燒后生成物（Pb、P、S化合物等）的腐蝕，還要經(jīng)受混合氣體吸入時冷區(qū)狀態(tài)溫度（常溫狀態(tài)）到氣體燃燒后高溫狀態(tài)過程中2000-2500攝氏度的反復(fù)溫度變化。廣東寶馬X1
