style="text-indent:25px">火花塞常見問題：當汽車出現(xiàn)熄火、提前點火、抖動、怠速不穩(wěn)等狀況時有可能是火花塞出現(xiàn)了一些棘手問題。1為什么說火花塞燃燒狀態(tài)非常重要？因為根據(jù)燃燒狀態(tài)（熏黑積碳、良好、過度燃燒），可以判斷火花塞的適合性和發(fā)動機的狀態(tài)，燃燒狀態(tài)隨火花塞受熱溫度而變化，可以從火花塞燃燒后的表現(xiàn)來做出推斷。2、火花塞過度燃燒會導(dǎo)致什么結(jié)果？火花塞過度燃燒會導(dǎo)致提前點火。過度燃燒時，發(fā)火部絕緣體表面變成白熾狀態(tài)，附著的熔渣（沉積物）呈斑點狀，如果過度燃燒程度嚴重會導(dǎo)致異常燃燒（提前點火）有可能損壞發(fā)動機。3、火花塞熏黑的原因？空燃比（A/F）過濃，電力系統(tǒng)不良（高電壓線龜裂，斷線）長時間怠速、連續(xù)低速運轉(zhuǎn)等，都可能導(dǎo)致火花塞熏黑，一旦火花塞點火部位附著有碳，天津路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞型號，點火線圈產(chǎn)生的高壓電就可能過積碳逃跑，天津路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞型號，天津路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞型號，導(dǎo)致熄火，行駛中出現(xiàn)故障及發(fā)動不良等現(xiàn)象。不同材質(zhì)火花塞的使用壽命也不相同。天津路虎發(fā)現(xiàn)神行/極光/發(fā)現(xiàn)4/攬勝火花塞型號</p><div

style="text-indent:25px">火花塞的點火性能是指什么？是通過火花塞給混合氣點火，燃燒的性能?；鸹ㄩg隙之間從點火到混合氣的燃燒過程，可以分為四個階段。一階段指在火花塞間隙間點火，第二階段是火炎核的行成，第三階段是火炎核的成長擴大，第四階段是點燃混合氣體，讓其燃燒。在整個過程中第三階段火花塞電極間（中心電極和側(cè)電極）的消減火炎作用（電極奪走火炎核的熱能）有可能將火炎核的火熄滅，造成點火失敗，因此需要確保此處消減火炎作用盡量減?。ɑ鹧缀说某砷L直接影響火花塞的點火性能），為了提高火花塞點火性能，NGK火花塞采取了一系列的方法，如在中心電極處設(shè)置了90度V字形切口（V字形切口中心電極火花塞），把中心電極做細（貴金屬火花塞），擴大點火間隙（大間隙火花塞），點火位置設(shè)定在燃燒室中心部位附近（突出型火花塞）。河北電裝鉑金火花塞店鋪單銥金火花塞使用壽命為4-5萬公里。</p><div

NGK火花塞給混合氣點火，具有打火機的作用。為起打火機的作用，火花塞要在非常苛刻的條件下工作。發(fā)動機的點火流程：發(fā)動機吸入空氣與汽油混合-混合氣體壓縮-火花塞點燃混合氣體-混合氣體爆發(fā)能量轉(zhuǎn)化成動能，期間火花塞承受的電壓可以達到20000v-30000v，電極材料還要承受混合氣體燃燒后生成物（Pb、P、S化合物等）的腐蝕，還要經(jīng)受混合氣體吸入時冷區(qū)狀態(tài)溫度（常溫狀態(tài)）到氣體燃燒后高溫狀態(tài)過程中2000-2500攝氏度的反復(fù)溫度變化。</p><p style="text-indent:25px">火花塞的熱值：決定火花塞熱值大小的是它的結(jié)構(gòu)，我們前面說的裙體對火花塞來說是個很重要的名詞，裙體與空氣接觸的面積就決定了火花塞的熱值。火花塞裙體部分與空氣接觸的面積越大，火花塞的散熱越好，火花塞本身的溫度就越低，即該火花塞熱值就越?。幌喾?，火花塞的裙體與空氣的接觸面積越小，火花塞的散熱就越差，火花塞本身的溫度就越高，即該火花塞的熱值就越大。需要注意的是，Champion和博世火花塞的表示方法是數(shù)字越小熱值越高，NGK和電裝的表示方法是數(shù)字越大熱值越高。劣質(zhì)汽油或者添加劑也會導(dǎo)致火花塞陶瓷體的污損。</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)火花塞價格低廉，大概價格在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)濟壽命大概在2-3萬萬公里。這里說的經(jīng)濟壽命是指在火花塞的綜合點火性能下降幅度較大的時間點之前，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火間隙會變大，點火性能隨之降低，過大的點火間隙同時需要點火線圈提供更高的點火電壓，一但點火電壓超過線圈的負荷就會造成損耗。還有就是火花塞點火性能下降會增加油耗及點火成功率，出現(xiàn)車子啟動困難，經(jīng)常熄火的狀況。判斷火花塞是否應(yīng)該更換還可以利用設(shè)備進行檢測。河南原廠配套火花塞廠家</p><p
