Kagawo makina carburetor udindo kusakaniza petulo ndi mpweya mu mlingo woyenera ndi kupereka osakaniza izi masilindala. Ngakhale samagwiritsidwa ntchito m'magalimoto atsopano, ma carburetor amapereka mafuta kumainjini agalimoto iliyonse, kuyambira pamagalimoto othamanga mpaka magalimoto apamwamba kwambiri. Amagwiritsidwa ntchito ku NASCAR mpaka 2012 ndipo ambiri okonda magalimoto akale amagwiritsa ntchito magalimoto opangidwa ndi carbureti tsiku lililonse. Ndi ambiri okonda diehard, carburetors ayenera kupereka chinachake chapadera kwa iwo amene amakonda magalimoto.

Kodi carburetor imagwira ntchito bwanji?

Carburetor amagwiritsa ntchito vacuum yomwe imapangidwa ndi injini kuti ipereke mpweya ndi mafuta kumasilinda. Dongosololi lakhala likugwiritsidwa ntchito kwa nthawi yayitali chifukwa cha kuphweka kwake. kupuma imatha kutsegula ndi kutseka, kulola mpweya wochuluka kapena wochepa kulowa mu injini. Mpweya uwu umadutsa pa khomo lopapatiza lotchedwa ntchito. Vacuum ndi zotsatira za mpweya wofunikira kuti injini isagwire ntchito.

Kuti mudziwe momwe venturi imagwirira ntchito, lingalirani mtsinje womwe umayenda bwino. Mtsinje uwu umayenda mothamanga kwambiri ndipo kuya kwake kumakhala kosasintha konsekonse. Ngati pali kagawo kakang'ono mumtsinjewu, madziwo amayenera kuthamanga kuti voliyumu yomweyi idutse pakuya komweko. Mtsinje ukangobwerera m'lifupi mwake pambuyo pa botolo, madzi amayesabe kusunga liwiro lomwelo. Izi zimapangitsa madzi othamanga kwambiri kumbali yakutali ya botolo kuti akope madzi oyandikira botolo, kupanga vacuum.

Chifukwa cha chubu cha venturi, pali vacuum yokwanira mkati mwa carburetor kotero kuti mpweya wodutsamo nthawi zonse umakoka mpweya kuchokera ku carburetor. jeti. Jeti ili mkati mwa chubu cha Venturi ndipo ndi dzenje lomwe mafuta amalowamo chipinda choyandama akhoza kusakanikirana ndi mpweya musanalowe m'masilinda. Chipinda choyandama chimakhala ndi mafuta pang'ono ngati chosungira ndipo chimalola mafuta kuyenda mosavuta ku jet ngati pakufunika. Pamene valve yotsekemera imatsegulidwa, mpweya wochuluka umalowetsedwa mu injini, kubweretsa mafuta ochulukirapo, zomwe zimawonjezera mphamvu ya injini.

Vuto lalikulu ndi kapangidwe kameneka ndikuti mpweya uyenera kukhala wotseguka kuti injini ipeze mafuta. Mphuno imatsekedwa popanda ntchito, choncho ndege yopanda ntchito amalola mafuta pang'ono kulowa m'masilinda kuti injini isayime. Zina zing'onozing'ono ndi monga mpweya wochuluka wotuluka mu chipinda (zipinda zoyandama).

Mu mafuta dongosolo

Ma carburettor apangidwa mosiyanasiyana komanso kukula kwake kwazaka zambiri. Mainjini ang'onoang'ono atha kugwiritsa ntchito kabureta imodzi yokha ya nozzle kuti apereke mafuta ku injini, pomwe ma injini akulu amatha kugwiritsa ntchito ma nozzles khumi ndi awiri kuti asayende. Chubu chomwe chili ndi venturi ndi jet chimatchedwa mbiya, ngakhale kuti mawuwa nthawi zambiri amagwiritsidwa ntchito pokhudzana ndi ma carburetors ambiri.

M'mbuyomu, ma carburetor okhala ndi mipiringidzo yambiri akhala mwayi waukulu wamagalimoto okhala ndi zosankha monga masinthidwe a 4- kapena 6-cylinder. Migoloyo ikachuluka, m’pamenenso mpweya ndi mafuta ochuluka zimalowa m’masilindawo. Ma injini ena adagwiritsanso ntchito ma carburetor angapo.

Magalimoto amasewera nthawi zambiri ankachokera ku fakitale yokhala ndi carburetor imodzi pa silinda, zomwe zidakhumudwitsa amakanika awo. Zonsezi zinkayenera kukonzedwa payekhapayekha, ndipo zopangira magetsi (zomwe nthawi zambiri zimachita ku Italy) zinali zokhudzidwa kwambiri ndi zolakwika zilizonse. Iwo ankafunanso kukonzedwa nthawi zambiri. Ichi ndi chifukwa chachikulu jekeseni mafuta poyamba otchuka mu magalimoto masewera.

Kodi ma carburetor onse apita kuti?

Kuyambira m'ma 1980, opanga akhala akuchotsa ma carburetor mokomera jekeseni wamafuta. Onsewa amagwira ntchito yofanana, koma ma injini amakono ovuta adangosintha kuchokera ku ma carburetor kuti alowe m'malo ndi jakisoni wamafuta olondola (komanso osinthika). Pali zifukwa zingapo zochitira izi:

• Jakisoni wamafuta amatha kupereka mafuta mwachindunji ku silinda, ngakhale thupi lopumira nthawi zina limagwiritsidwa ntchito kulola jekeseni imodzi kapena ziwiri kuti zipereke mafuta kumasilinda angapo.

• Idling ndizovuta ndi carburetor, koma zosavuta kwambiri ndi majekeseni amafuta. Izi ndichifukwa choti jekeseni wamafuta amatha kungowonjezera mafuta pang'ono ku injini kuti ipitilize kugwira ntchito pomwe carburetor ili ndi chiwopsezo chotsekedwa osagwira ntchito. Jet yopanda ntchito ndiyofunikira kuti injini ya carburetor isayime pamene throttle yatsekedwa.

• Jekeseni wamafuta ndi wolondola kwambiri ndipo amadya mafuta ochepa. Chifukwa cha izi, mpweya wa gasi umakhala wocheperako panthawi yobaya mafuta, choncho mwayi woyaka moto umachepa.

Ngakhale zitatha, ma carburetor amapanga gawo lalikulu la mbiri yamagalimoto ndipo amagwira ntchito mwamakina komanso mwanzeru. Pogwira ntchito ndi injini zama carbureted, okonda atha kupeza chidziwitso chogwira ntchito cha momwe mpweya ndi mafuta zimaperekedwa ku injini kuti iyatse ndi kuyendetsa.
