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(hào)F8DCOR中的數(shù)字8，要特別說明的是這個(gè)“8”不是指8度，而是指用“8”表示的一個(gè)溫度范圍值。由于汽油在發(fā)動(dòng)機(jī)中不可能完全燃燒，會(huì)有少量的碳粉沉積，這些碳粉會(huì)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(huì)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(huì)自己燃燒了，我們把這個(gè)碳粉自己燃燒的溫度范圍就稱為該款發(fā)動(dòng)機(jī)適合的火花塞熱值。為了保證發(fā)動(dòng)機(jī)安全可靠運(yùn)行以及保持其穩(wěn)定的性能，必須定期更換火花塞。</p><div

1、高壓電擊穿電極間的介質(zhì)產(chǎn)生電火花； 2、電弧高溫加熱混合氣后產(chǎn)生火焰核； 3、火焰核成長(zhǎng)變大； 4、火焰核點(diǎn)燃混合氣。整個(gè)放電過程是極其短暫的，大約只有千分之一秒。影響火花放電的因素很多，比如點(diǎn)火線圈提供的高壓電的大小、火花塞電極間隙、電極的形狀及材料、火花塞的絕緣狀況、可燃混合氣的濃度、發(fā)動(dòng)機(jī)壓縮比的高低，等等。熱值越高，表示火花塞的吸熱與散熱平衡能力越強(qiáng)。安徽路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞廠家</p><p style="text-indent:25px">單鉑金火花塞使用壽命為3-4萬公里。安徽路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞廠家</p><p style="text-indent:25px">如果火花塞的技術(shù)狀態(tài)良好，產(chǎn)生的電火花能量高，可燃混合氣就容易被點(diǎn)燃，并且燃燒更加迅速、充分，發(fā)動(dòng)機(jī)的動(dòng)力就能釋放；相反，如果火花塞技術(shù)狀態(tài)不好，產(chǎn)生的電火花能量低，甚至經(jīng)常出現(xiàn)斷火的情況，就會(huì)導(dǎo)致可燃混合氣點(diǎn)燃困難，即使點(diǎn)燃后由于初始能量小，后期的燃燒也比較緩慢，發(fā)動(dòng)機(jī)的動(dòng)力就會(huì)受到很大的限制。打一個(gè)比方來說，我們想要點(diǎn)燃一堆木柴，我們可以用火柴來點(diǎn)，也可以用火把來點(diǎn)。顯然，用火把比用火柴點(diǎn)更容易點(diǎn)燃，木柴燃燒的也更快。所以，火花塞點(diǎn)火時(shí)釋放出的能量的大小，直接決定可燃混合氣的燃燒狀態(tài)，進(jìn)而影響發(fā)動(dòng)機(jī)動(dòng)力性能。因此說，火花塞的性能高低，直接影響發(fā)動(dòng)機(jī)性能的好壞，火花塞對(duì)發(fā)動(dòng)機(jī)是極為重要的，被稱作“心臟中的心臟”。安徽路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞廠家</p><p
