style="text-indent:25px">如果我們能把火花塞拆下來，那就更容易判斷了。火花塞的正常狀態(tài)是：電極部分呈灰白色，灰黃色或淺棕色，電極間隙大約在0.8~1.1mm之間。如果拆下來的火花塞上面沾滿了油污，或者電極燒蝕嚴(yán)重、間隙過大、腐蝕變形、雜質(zhì)沉積等，或者絕緣體破損等，這樣的火花塞就需要更換了。不過如果火花塞上只是積碳較多，但電極沒有問題，這樣的火花塞是可以清洗后繼續(xù)使用的。還有一種是火花塞上面有一圈電暈，很多修理工說它是漏氣了，必須換火花塞，但事實(shí)并非如此，它是由于高壓電與機(jī)油分子共同作用產(chǎn)生的，對(duì)火花塞的性能沒有任何影響。</p><p style="text-indent:25px">火花塞是發(fā)動(dòng)機(jī)上的一個(gè)重要零部件，被稱作“發(fā)動(dòng)機(jī)的心臟”，它性能的好壞直接影響發(fā)動(dòng)機(jī)的工作狀況。同時(shí)火花塞也是一個(gè)消耗品，需要定期更換。它的價(jià)格也不便宜，從幾十元一個(gè)到上百元一個(gè)的都有，一個(gè)普通的四缸發(fā)動(dòng)機(jī)，換一次火花塞工時(shí)費(fèi)加上備件錢至少要好幾百塊錢，放誰身上都挺心疼的。這就讓我們這些車主非常糾結(jié)了：換早了浪費(fèi)，換晚了又怕傷害發(fā)動(dòng)機(jī)。那么如何在適合的時(shí)機(jī)更換火花塞呢？家用車如何判斷是否需要更換火花塞呢？下面老侯來給大家分析一下這個(gè)問題?；鸹ㄈ趯?shí)際使用中還是會(huì)不停的損耗的。</p><div

style="text-indent:25px">不同材質(zhì)火花塞的使用壽命：1、鎳銅合金火花塞，此種材質(zhì)火花塞價(jià)格低廉，大概價(jià)格在10元左右一支，屬于基本型的產(chǎn)品，電極材質(zhì)是“鎳銅合金”，中心電極大概2.5毫米，因其材質(zhì)使用中損耗較快，經(jīng)濟(jì)壽命大概在2-3萬萬公里。這里說的經(jīng)濟(jì)壽命是指在火花塞的綜合點(diǎn)火性能下降幅度較大的時(shí)間點(diǎn)之前，并非此種材質(zhì)火花塞到了3萬公里就損換不能使用，只是如果繼續(xù)使用后火花塞電極損耗過大后點(diǎn)火間隙會(huì)變大，點(diǎn)火性能隨之降低，過大的點(diǎn)火間隙同時(shí)需要點(diǎn)火線圈提供更高的點(diǎn)火電壓，一但點(diǎn)火電壓超過線圈的負(fù)荷就會(huì)造成損耗。還有就是火花塞點(diǎn)火性能下降會(huì)增加油耗及點(diǎn)火成功率，出現(xiàn)車子啟動(dòng)困難，經(jīng)常熄火的狀況。NGK火花塞是以數(shù)字2~11來表示熱值。江蘇捷豹XE

style="text-indent:25px">至于火花塞更換周期也有比較特殊的情況，那就是奧迪汽車的火花塞更換周期只有短短的兩萬公里。這個(gè)更換周期是所有車型中屬于非常短的，它使用鉑金、銥金類的火花塞，但是使用壽命卻比銅鎳火花塞都要短，這究竟是為什么呢？這主要是因?yàn)?，奧迪發(fā)動(dòng)機(jī)的工作條件是非?？量痰?，它使用的是渦輪增壓缸內(nèi)直噴發(fā)動(dòng)機(jī)，做功時(shí)氣缸內(nèi)壓力大、溫度高，火花塞要承受巨大的壓力沖擊和溫度變化，這就對(duì)它的機(jī)械強(qiáng)度提出了很高的要求；此外，奧迪的火花塞每一個(gè)工作循環(huán)點(diǎn)火兩次，而不合適一次，這樣兩萬公里就相當(dāng)于其他車型的四萬公里；還有就是奧迪發(fā)動(dòng)機(jī)采用分層燃燒技術(shù)，在火花塞附近可燃混合氣濃度高、、燃燒快，對(duì)火花塞的損耗也就更大。車企實(shí)驗(yàn)發(fā)現(xiàn)，火花塞在兩萬公里之后性能就出現(xiàn)了下降，因此，為了保證奧迪發(fā)動(dòng)機(jī)性能的穩(wěn)定可靠、動(dòng)力充分發(fā)揮，就規(guī)定兩萬公里更換火花塞。現(xiàn)在有很多奧迪4s店規(guī)定，如果兩萬公里不更換火花塞，視為自動(dòng)脫保。江蘇捷豹XE
