單側(cè)極與多側(cè)極點(diǎn)火電極，傳統(tǒng)單側(cè)極點(diǎn)火電極有一個明顯的缺點(diǎn)，即側(cè)電極蓋住了中心電極。當(dāng)兩極間高壓放電時，火花間隙處的混合氣將吸收火花熱量并因電離被啟動而形成“火核”。火核形成的場所一般在接近側(cè)電極處，熱量將較多地被側(cè)電極吸收，即電極的“消焰作用”，它減少了火花能量，降低了跳火性能。于是，在上世紀(jì)20年代，出現(xiàn)了三側(cè)極點(diǎn)火電極。與單側(cè)極相比，多側(cè)極的火花間隙由多個側(cè)電極的斷面（沖成圓孔）和中心電極的圓柱面構(gòu)成，這種旁置式的火花間隙消除了側(cè)電極蓋住中心電極的缺點(diǎn)，增加了火花的“可達(dá)性”，火花能量較大，較容易深入汽缸內(nèi)部，有助于改善混合氣燃燒狀況并減少廢氣排放。由于多側(cè)極提供了多個跳火通道，因而延長了使用壽命，提高了點(diǎn)火的可靠性。這里必須指出，放電的瞬間只能是一條通道跳火，不可能多側(cè)極同時跳火。高速攝影的放電過程證明了這一點(diǎn)

點(diǎn)火電極是工業(yè)燃燒器、汽車發(fā)動機(jī)等點(diǎn)火系統(tǒng)中的一個主要元件，點(diǎn)火電極的作用是把點(diǎn)火線圈產(chǎn)生的高壓電引入發(fā)動機(jī)汽缸，在點(diǎn)火電極電極的間隙之間產(chǎn)生火花點(diǎn)燃混合氣。點(diǎn)火電極壽命應(yīng)該是多久？通常而言，電阻點(diǎn)火電極的壽命為2萬公里，鉑金點(diǎn)火電極的壽命為4萬公里，而銥金工業(yè)點(diǎn)火電極的壽命則能達(dá)到6至8萬公里。如果發(fā)現(xiàn)車輛耗油量增大時，可以考慮是否換個點(diǎn)火電極，一般修理廠會建議兩三萬公里就更換，因?yàn)檫@時點(diǎn)火電極雖然沒有完全損壞，但效能有所下降。 </p> <p> <br /> </p> <p> <br /> </p><p> 點(diǎn)火電極采用鈦金屬表層處理，鋁金屬鋼針、高溫防裂95陶瓷材料，適應(yīng)1500度以上的長期燃燒及帶風(fēng)力磨損的條件下不損壞、變形、氧化。點(diǎn)火電極絕緣體組件應(yīng)能耐受工頻(50Hz)電壓2200vV(有效值)，歷時30s的試驗(yàn)。材料：點(diǎn)火電極中心電極和側(cè)電極的導(dǎo)電性能取決于電極與混合氣接觸情況，所以，電極對抗腐蝕性的要求極高。同時，燃燒時的溫度極高，電極材料對耐熱性要求高。因此，許多點(diǎn)火電極采用鎳錳合金。為提高耐熱性能，也有的點(diǎn)火電極采用鎳包銅的材料。銅制墊圈除起導(dǎo)熱性能外，也起密封作用。絕緣體用高氧化鋁陶瓷制成

點(diǎn)火電極雖然只是一個小零件，但它卻極其重要，沒有它發(fā)動機(jī)會動彈不得。由于汽油的燃點(diǎn)較高(約400度左右)，因而需要使用強(qiáng)制點(diǎn)火方式點(diǎn)燃混合氣。當(dāng)活塞到達(dá)壓縮行程上止點(diǎn)時，點(diǎn)火線圈的低壓線圈內(nèi)就會有一個脈沖電流通過，低壓線圈的脈沖電流通過時，就會在點(diǎn)火線圈的高壓線圈內(nèi)產(chǎn)生一個很高的脈沖電壓，這個很高的電壓如有一個適當(dāng)?shù)亩丝谶M(jìn)行釋放，這個端口就會產(chǎn)生一個很強(qiáng)的高壓火花，點(diǎn)火電極就是這個我們所要的端口。當(dāng)點(diǎn)火電極在活塞壓縮行程將要到達(dá)上止點(diǎn)時，適時的放出高壓火花，就會點(diǎn)燃活塞燃燒室內(nèi)的燃油混合氣體，產(chǎn)生高壓氣體，推動活塞下行作功，使發(fā)動機(jī)正常工作，當(dāng)然這個點(diǎn)火時間一定要準(zhǔn)確，火花要足以點(diǎn)燃燃油混合氣體，保證發(fā)動機(jī)連續(xù)工作。
