Chilankhulo
Ntchito ya spark plug ndikuyatsa. Silinda ikafika pakatikati pakufa, petulo imatha kuwotchedwa kuti ipange mphamvu poyatsira spark plug. Choncho, mphamvu yoyatsira moto ya spark plug, imakhala bwino. Ngati mphamvu yoyaka moto ya spark plug ndi yoyipa, nthawi yoyenera kuyatsa idzaphonya, zomwe zimapangitsa kuti mafuta asatenthedwe, ndipo mafuta oyaka sagwiritsidwa ntchito mokwanira. Kumverera mwachidziwitso ndikuti mphamvu ya galimotoyo ndi yosauka, mafuta ogwiritsidwa ntchito ndi aakulu, ndipo padzakhala kuchuluka kwa carbon deposits zosaoneka. Kusintha ma spark plugs ndichinthu chokonza nthawi zonse ndipo chimafunika kusinthidwa pafupipafupi, ndiye ndi ma kilomita angati omwe akuyenera kusinthidwa? Ndi zizindikiro zotani za galimoto yomwe ikufunika kusinthidwa?

Pali pafupifupi ma kilomita. Ma spark plugs wamba ayenera kusinthidwa pamtunda wa makilomita pafupifupi 40,000, ndipo mapulagi a platinamu ayenera kusinthidwa kukhala makilomita 80,000 mpaka 100,000. Ndikokwanira kutsatira chiwerengero cha makilomita pansi pa ntchito yachibadwa ya galimoto. Pali mabuku ambiri okonza omwe amalimbikitsa mtunda wocheperako kuposa ma kilomita awa. Ma spark plug wamba amafunikira kusinthidwa pamtunda wa makilomita 30,000. Mutha kuwonjezera kuchuluka kwa ma kilomita moyenerera, chifukwa magalimoto ambiri amakhala ndi ntchito yabwino yoyatsira ma spark plugs okhala ndi makilomita 30,000. Chifukwa chimene wopanga amapempha kuti asinthe mofulumira ndi chifukwa chakuti galimoto ya 30,000-km ikadali yatsopano, ndipo m'pofunika kusunga galimotoyo kuti ikhale yabwino kwambiri kuti galimotoyo ikhale ndi mbiri yabwino.
Makilomita omwe ali pamwambawa ndi ogwiritsira ntchito bwino galimoto. Ngati galimotoyo ndi yachiwawa komanso yachiwawa, kapena nthawi zambiri imagwiritsidwa ntchito kukoka katundu ndi anthu, iyenera kusinthidwa pasadakhale. Kuphatikiza pa izi, ndizofala kuti spark plug imalephera. Madalaivala ambiri akale sasintha spark plug kwa nthawi yayitali, ndipo sasintha pomwe chiŵerengero cha makilomita chafika. Iyi ndi njira yolakwika yosamalira galimoto. Ngakhale spark plug sidasweka, mphamvu ndi kugwiritsa ntchito mafuta zimakhudzidwa mphamvu yakuyatsa ikatsika. Zimangotsika pang'ono tsiku ndi tsiku, ndipo kusintha kumachedwa kwambiri ndipo sindikuzindikira.
Ngati imodzi mwa spark plugs yathyoledwa, chodabwitsa ndi chakuti injini imagwedezeka kwambiri ndipo kuthamanga kwake kumakhala kofooka. Chifukwa pali silinda imodzi yochepa yoti igwire ntchito, mwachibadwa ntchitoyo siili bwino ndipo mphamvu imatsika. Ngati pali choyesa makompyuta, ndizosavuta kuzindikira kuti silinda iti yomwe sikugwira ntchito. Ngati palibe choyesa pakompyuta, mutha kutulutsa mizere ya silinda imodzi ndi imodzi kuti muyese. Pambuyo potulutsa mzere wa silinda ya silinda inayake, ngati kugwedezeka kuli koopsa, zikutanthauza kuti spark plug ya silinda iyi sinasweka. Ngati kuuma kwa jitter sikusintha, zikutanthauza kuti spark plug ya silinda iyi yathyoka, ndipo mutha kuyigawa kuti iwunikenso.
Spark plug yathyoka isanafikire kuchuluka kwa ma kilomita kuti ilowe m'malo. Nthawi zambiri, imodzi yokha yowonongeka ingasinthidwe. Ngati ili pafupi ndi kuchuluka kwa makilomita oti alowe m'malo, tikulimbikitsidwa kuti musinthe onse. Mwachitsanzo, ma spark plugs ayenera kusinthidwa kukhala makilomita 100,000. Ngati imodzi yathyoledwa pamtunda wa makilomita 80,000, tikulimbikitsidwa kuti musinthe onse. Ngati imodzi yathyoledwa pamtunda wa makilomita 60,000, mutha kungosintha imodzi. Palibe mulingo wapamtunda wotsimikizira ngati zonse ziyenera kusinthidwa. Pankhani imodzi yosweka, plugs imodzi kapena ziwiri ziyenera kuchotsedwa kuti ziwone. Ngati kutentha kwamoto kuli bwino ndipo kusiyana kwake si kwakukulu, palibe chifukwa chosinthira, ndiye kodi mapulagi onse a spark amafunika kusinthidwa? Kusintha kuyenera kufufuzidwa kaye.
Chochitika chodziwika kuti spark plug iyenera kusinthidwa ndikuti injini imagwedezeka, liwiro lopanda ntchito silikhazikika, kuyatsa sikwabwino, kugwiritsa ntchito mafuta kumawonjezeka, ndipo mphamvu imachepa. Izi zikachitika, spark plug yafikanso pakusintha, ndipo kuganizira koyamba ndikulowetsa spark plug. Chotsani spark plug ndikuweruza momwe silinda imayaka poyang'ana ma elekitirodi a spark plug. Ngati electrode ndi yoyera komanso yofiirira, zikutanthauza kuti kuyaka kuli bwino. Ngati pali mpweya wa carbon pa electrode, ndi wakuda, zomwe zimasonyeza kuti kuyaka kwa silinda sikuli bwino. Kuphatikiza pa spark plug kuti ilowe m'malo, komanso kuti muwone ngati pali zolakwika zina. Palinso mulingo wina woweruza ngati m'malo. Onani kusiyana kwa electrode. Ngati kusiyana kukukulirakulira, kumafunika kusinthidwa. Koma choyamba, muyenera kudziwa kukula kwa kusiyana kwa electrode ya spark plug yatsopano. Mutha kudziwa ngati ikukula pambuyo pofananiza.
