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(dòng)機(jī)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(diǎn)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(diǎn)火能量就越大。但如果超出了點(diǎn)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(diǎn)火能量，反而由于電壓不足，造成火花塞丟火，同時(shí)，點(diǎn)火線圈由于長時(shí)間處于超負(fù)荷運(yùn)行，造成點(diǎn)火線圈負(fù)荷過大而發(fā)熱，使內(nèi)部短路或斷路損壞，大部分的點(diǎn)火線圈設(shè)計(jì)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(diǎn)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(diǎn)燃混合氣的熱量不夠，造成不完全燃燒，使發(fā)動(dòng)機(jī)的動(dòng)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(diǎn)火線圈電壓冗余量不夠，反而會(huì)使點(diǎn)火不充分。廣東NGK雙銥金火花塞套裝火花塞從燃燒室導(dǎo)出熱量的速度高，火花塞的工作溫度越低，這樣的火花塞稱為冷型火花塞。</p><div

1、選用的火花塞外形尺寸必須與原車的完全一致，包括火花塞長度、螺紋的尺寸、電極的形狀與長度，等等。這樣才能保證火花塞正確的安裝到位，不會(huì)與氣門、活塞等發(fā)生運(yùn)動(dòng)干涉，同時(shí)確保各氣缸燃燒室的火焰中心在同一位置；另外同一臺(tái)發(fā)動(dòng)機(jī)上的火花塞電極材料也必須完全相同，不同的電極材料會(huì)影響火花塞的使用壽命，發(fā)火性能也有差異，會(huì)導(dǎo)致各氣缸點(diǎn)火性能不平衡。</p><p style="text-indent:25px">不同的火花塞擁有著不同的技術(shù)優(yōu)點(diǎn)，影響著汽車的駕駛性和安全性，只有深知不同品牌材質(zhì)間的火花塞性能特點(diǎn)，才能為愛車選擇正確的產(chǎn)品?；鸹ㄈ狞c(diǎn)火性能是指通過火花塞給混合氣點(diǎn)火使其燃燒的性能，火花間隙之間從點(diǎn)火到混合氣的燃燒過程?；鸹ㄈ麩嶂凳窃趺椿厥?？火花塞必須散掉來自燃燒氣體的熱量，熱值就是指其散熱的程度。低功率小排量不容易產(chǎn)生過熱的發(fā)動(dòng)機(jī)用熱型。高功率或者渦輪增壓容易產(chǎn)生過熱的發(fā)動(dòng)機(jī)用冷型。更換火花塞的周期？即使正確使用，由于火花塞是消耗品，也需要定期進(jìn)行檢測和更換，不同材質(zhì)的火花塞使用壽命也不同，鎳合金2-3萬，單鉑金3-4萬，單銥金4-5萬，雙鉑金6-8萬，銥鉑金6-8萬，雙銥金8-10萬。熱值越高，表示火花塞的吸熱與散熱平衡能力越強(qiáng)。</p><div

style="text-indent:25px">如何正確選擇火花塞的熱值。這一點(diǎn)是很多人不理解或者忽略的，其實(shí)火花塞的熱值非常重要，它表示的是火花塞絕緣體裙部吸熱與散熱的平衡能力。熱值越高，表示火花塞的吸熱與散熱平衡能力越強(qiáng)，火花塞從燃燒室導(dǎo)出熱量的速度高，火花塞的工作溫度越低，這樣的火花塞稱為冷型火花塞；相反，熱值越低，表示火花塞的吸熱與散熱平衡能力越差，火花塞從燃燒室導(dǎo)出熱量的速度低，火花塞的工作溫度越高，這樣的火花塞稱為熱型火花塞。一般在火花塞的型號(hào)中專門有一個(gè)數(shù)字來表示火花塞的熱值，不過不同品牌的火花塞標(biāo)識(shí)方法不同，沒有一個(gè)統(tǒng)一的標(biāo)準(zhǔn)。比如說常見的博世火花塞，它是以數(shù)字2~10來表示熱值，數(shù)字越大熱值越高；而NGK火花塞是以數(shù)字2~11來表示熱值，數(shù)字越大表示熱值越低；其它的比如電裝的火花塞，它是以數(shù)字9~35來表示熱值，數(shù)字越大表示熱值越低。單銥金火花塞使用壽命為4-5萬公里。湖北NGK雙鉑金火花塞店鋪</p><p

style="text-indent:25px">更換火花塞時(shí)必須有**的工具，并且要正確使用，這對于我們普通的車主來說就已經(jīng)很困難了?；鸹ㄈ鹦逗桶惭b時(shí)，必須使用扭力扳手，按規(guī)定的力矩扭緊，過松會(huì)導(dǎo)致火花塞漏氣，過緊會(huì)損傷缸蓋，甚至導(dǎo)致螺紋滑牙，那麻煩可就大了。另外對于有些采用分電器的車型來說，我們還要記住缸線的順序，如果缸線錯(cuò)亂是打不著火的。還有就是在更換過程中的一些小細(xì)節(jié)，比如如何防止異物掉入氣缸，如何防止火花塞電極受損，等等，都需要一定的經(jīng)驗(yàn)才行。所以，我是不建議車主自己更換火花塞的，去修理廠其實(shí)也用不了多少錢。廣東NGK雙銥金火花塞套裝</p></p><br
