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(lái)說(shuō)，我們想要點(diǎn)燃一堆木柴，我們可以用火柴來(lái)點(diǎn)，也可以用火把來(lái)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(shuō)，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”。江西豐田花冠卡羅拉雷凌威馳火花塞店鋪銥鉑金火花塞是指火花塞的中心電極采用銥金，側(cè)電極采用鉑金材質(zhì)。</p><div

NGK火花塞從低速到高速，按照能把發(fā)動(dòng)機(jī)的功率全部發(fā)揮出來(lái)的思想進(jìn)行了設(shè)計(jì)。1、能夠承受更廣范圍的溫度區(qū)間，為了使大量熱量更快的散去，在中心電極上直到前端嵌入了銅芯，嵌入銅芯的構(gòu)造可以讓火花塞更耐燒耐積碳（嵌入銅芯的火花塞可以更好的散熱）。2、使用新型陶瓷的高氧化鋁陶瓷為絕緣體，此種陶瓷有更好的絕緣性、更好的導(dǎo)熱性（能防止過(guò)渡燃燒，提升抗沖擊性）、更好的機(jī)械強(qiáng)度及抗熱沖擊性（急冷急熱轉(zhuǎn)換）。3、使用特殊的粉末將絕緣體和主體金屬連接在一起，確保其具備良好的氣密性。4、良好的耐久性，通過(guò)對(duì)電極材質(zhì)的選擇可確保火花塞有良好的使用壽命。單鉑金火花塞使用壽命為3-4萬(wàn)公里。山西電裝鉑金火花塞性能</p><p
