Pulagi yoyatsira injini ya dizilo
Pali mitundu yosiyanasiyana ya ma plug owunikira, ndipo pakadali pano omwe amagwiritsidwa ntchito kwambiri ndi atatu awa: wamba; Mtundu wotsika wa preheater. Pulagi yowunikira imakulungidwa pakhoma lililonse la chipinda choyaka moto cha injini. Nyumba ya glow plug ili ndi coil yotsutsa glow plug yomwe imayikidwa mu chubu. Mphamvu imadutsa mu coil yotsutsa, zomwe zimapangitsa chubu kutentha. Chubucho chili ndi malo akuluakulu ndipo chingapangitse mphamvu zambiri zotentha. Mkati mwa chubucho muli zinthu zoteteza kuti coil yotsutsa isakhudze khoma lamkati la chubu chifukwa cha kugwedezeka. Chifukwa cha magetsi osiyanasiyana a batri (12V kapena 24V) ndi chipangizo chotenthetsera chomwe chimagwiritsidwa ntchito, magetsi oyesedwa a ma plug owunikira osiyanasiyana nawonso ndi osiyana. Chifukwa chake, onetsetsani kuti mwagwiritsa ntchito mtundu woyenera wa ma plug owunikira. Kugwiritsa ntchito ma plug owunikira olakwika kungayambitse kuyaka msanga kapena kutentha kosakwanira.
Mu injini zambiri za dizilo, ma plug owunikira olamulidwa ndi kutentha amagwiritsidwa ntchito. Mtundu uwu wa plug yowunikira uli ndi heater coil, yomwe kwenikweni imakhala ndi ma coil atatu, blocking coil, equalizing coil ndi rapid heating coil, ndipo ma coil atatuwa amalumikizidwa motsatizana. Pamene magetsi adutsa kudzera mu glow plug, kutentha kwa rapid heating coil yomwe ili kumapeto kwa glow plug kumakwera koyamba, zomwe zimapangitsa kuti glow plug itenthe kwambiri. Popeza kukana kwa equalizing coil ndi blocking coil kumawonjezeka kwambiri pamene kutentha kwa heating coil kumawonjezeka, mphamvu yamagetsi kudzera mu heating coil imachepa moyenerera. Umu ndi momwe glow plug imalamulira kutentha kwake. Ma plug ena owunikira alibe equalizing coils omwe adayikidwa chifukwa cha kukwera kwawo kwa kutentha. Ma plug owunikira olamulidwa ndi kutentha omwe amagwiritsidwa ntchito mu super glow plugs atsopano safuna masensa amagetsi, zomwe zimapangitsa kuti makina otenthetsera ayambe kusinthasintha. [2]
Chowunikira chowunikira chowunikira mtundu wa preheater chosinthira
Chipangizo chowunikira cha mtundu wa glow plug monitor chimakhala ndi ma glow plug, ma glow plug monitor, ma glow plug relay ndi zinthu zina. Chowunikira cha glow plug chomwe chili pa dashboard chimawonekera pamene ma glow plugs ali otentha.
Chowunikira cha glow plug chimayikidwa pa chida chowunikira momwe plug yowala imatenthetsera. Chowunikira cha glow chimakhala ndi chowunikira cholumikizidwa ku gwero lomwelo lamagetsi. Ndipo chowunikira cha glow chikasanduka chofiira, chowunikira ichi chimasandukanso chofiira nthawi yomweyo (nthawi zambiri, chowunikira cha glow plug chiyenera kuyaka chofiira kwa masekondi 15 mpaka 20 pambuyo poti magetsi ayatsidwa). Zowunikira zingapo za glow plug zimalumikizidwa nthawi imodzi. Chifukwa chake, ngati chimodzi mwa zowunikira za glow chatsekedwa, chowunikira cha glow plug chidzasanduka chofiira kale kuposa masiku onse. Kumbali ina, ngati chowunikira cha glow chatsegulidwa, zimatenga nthawi yayitali kuti chowunikira cha glow plug chiyake chofiira. Kutenthetsa chowunikira cha glow plug kwa nthawi yayitali kuposa nthawi yomwe yatchulidwa kudzawononga chowunikira cha glow plug.
Cholumikizira cha glow plug chimaletsa mphamvu zambiri kuti zisadutse mu chosinthira choyambira ndipo chimaonetsetsa kuti kutsika kwa magetsi chifukwa cha chowunikira cha glow plug sikukhudza ma glow plug. Cholumikizira cha glow plug chimakhala ndi ma relay awiri: pamene chosinthira choyambira chili pamalo a G (preheat), mphamvu imodzi yolumikizira kudzera mu chowunikira cha glow plug kupita ku glow plug; pamene chosinthira chili pamalo a START (start), cholumikizira china. Cholumikizira chimapereka mphamvu mwachindunji ku glow plug popanda kudutsa mu chowunikira cha glow plug. Izi zimaletsa glow plug kukhudzidwa ndi kutsika kwa magetsi chifukwa cha kukana kwa chowunikira cha glow plug panthawi yoyambitsa.
