怎樣判斷火花塞該換了
拆下(xia)火(huo)花(hua)塞(sai)觀(guan)(guan)察,根據(ju)以下(xia)的外觀(guan)(guan)顏色(se)觀(guan)(guan)察判斷火(huo)花(hua)塞(sai)的使用狀況:
如果是赤褐色或鐵銹色,表明火花塞正常;如果(guo)是漬油狀,表明火花塞間隙(xi)失調或供油過多,高壓線(xian)短(duan)路或斷(duan)路;如(ru)果是煙熏過的黑(hei)色(se),表明火花塞冷熱型(xing)選錯或混(hun)合(he)氣濃,機油(you)上竄;如(ru)果在頂(ding)端(duan)處與電極間有沉積(ji)(ji)物(wu)(wu),沉積(ji)(ji)物(wu)(wu)是(shi)油(you)性物(wu)(wu)時,證(zheng)明氣(qi)缸竄機油(you),與火(huo)(huo)花塞無關;如(ru)果沉積(ji)(ji)物(wu)(wu)是(shi)黑色時則(ze)說明火(huo)(huo)花塞積(ji)(ji)碳而旁(pang)路;沉積(ji)(ji)物(wu)(wu)為(wei)灰色則(ze)是(shi)因為(wei)汽油(you)中添(tian)加劑覆蓋了電極而導(dao)致的缺火(huo)(huo);如(ru)果(guo)火(huo)花塞嚴重燒(shao)蝕,頂(ding)端出現起疤(ba)、黑色紋路、破裂(lie)、電極熔化等現象,這就表明火(huo)花塞已(yi)經損(sun)壞,必(bi)須(xu)立即更換。
火花塞選購
在選擇火花(hua)(hua)塞(sai)時,必(bi)須保(bao)證舊火花(hua)(hua)塞(sai)與(yu)新火花(hua)(hua)塞(sai)的尺寸(cun)一致(zhi)。火花(hua)(hua)塞(sai)的尺寸(cun)會印在裙部陶瓷(ci)絕緣(yuan)體上(shang),只要(yao)保(bao)證新老火花(hua)(hua)塞(sai)的尺寸(cun)數字和字母一致(zhi)即可。
至于品牌選擇就因人而異了,同等價位之間的競品其實差距不是很大,選擇你喜歡并且有售后保障的火花塞品牌即可。
