Makina Ang'onoang'ono A injini ya Mafuta a Gasoline
Injini imayendera kwenikweni mpweya, pafupifupi magawo 14 a mpweya kupita ku imodzi ya mafuta.Choncho, ntchito ya dongosolo la mafuta ndikuyamba kusakaniza, mpweya ndi mafuta molingana bwino ndikuzipereka ku chipinda choyaka moto.Carburetor ndiye gawo lofunikira.Zimasakaniza mafuta ndi mpweya, ndipo m'mainjini ang'onoang'ono, zimakhalanso ndi mpope wamafuta, womwe umatulutsa mafuta kuchokera ku tanki ndikuupereka ku carburetor.
Makina ang'onoang'ono a injini ya carburetor ndi osavuta kupanga, osavuta ndiye kuti, ngati mumazolowera magalimoto.Ngati mumatha kuyendetsa njira yanu kudzera mumayendedwe a injini ndi zoyatsira, mutha kumvetsetsanso carburetion.
Yambani poganiza za atomizer yamafuta onunkhira.Mumafinya babu ndipo mafuta onunkhira amatuluka.Ngati mbaleyo ili ndi mafuta, mumapeza kusakaniza kwa mpweya ndi mafuta.Atomizer imawoneka yosavuta, koma mwina simunaganizepo za momwe imagwirira ntchito, kotero ngati phindu la kuphunzira za injini zazing'ono zamagesi, mutha kumvetsetsanso boudoir iyi yofunika.
Ndi atomizer, kufinya babu kumapangitsa mpweya kudzera mu chubu chopingasa, chomwe chikuwonetsedwa mu 1-17.Izi zimapanga malo otsika kwambiri pa jeti ya chubu cholumikizira chomwe chimafikira kumafuta onunkhira.Popeza mpweya wa mu botolo la atomizer palokha umakhala ndi mphamvu ya mpweya wabwino (mapaundi 14.7 pa sikweya inchi pamlingo wa nyanja, kucheperako pamalo okwera), amakakamiza mafuta onunkhiritsa kukwera mu chubu kupita kumtunda wapansi.Kenako mpweyawo umanyamula madonthowo ndi kuwatulutsa ngati utsi.
Izi ndi zomwe carburetor ikunena.Koma m’malo mwa mafuta onunkhira, jeti yake imanyamula mafuta a petulo.M’malo mouzira mpweya kudutsa nsonga ya jetiyo pogwiritsa ntchito babu, kaburetayo ali ndi silinda yooneka bwino kwambiri yotchedwa air horn imene injiniyo imagwiritsa ntchito vacuum, monga mmene zilili pa 1-18.
Injini yozungulira iwiri imagwiritsa ntchito vacuum yomwe imapangidwa mu crankcase pomwe pisitoni ikukwera.Vutoli limatsegula valavu ya bango ndikukokera mpweya kuchokera ku nyanga ya mpweya wa carburetor kuti apange malo otsika kwambiri.Mpweya wakunja ukamathamangira kuti mudzaze chotsekeracho, umapanga malo apadera ocheperako pang'ono kuzungulira nsonga ya jeti, kutulutsa mafuta ngati madontho omwe
Amapita ku Crankcase
Injini yozungulira inayi imagwiritsa ntchito vacuum yomwe imapangidwa mu silinda pamene pisitoni ikutsika.M'malo mothamangira mu crankcase, kusakaniza kwamafuta a mpweya kumapita mwachindunji mu silinda pamene valavu yolowetsa imatsegulidwa.Kupatula kusiyana kumeneku, njira yoperekera mafuta ku injini ziwirizi ndiyofanana.Kuthamanga kwa mpweya kudzera mu carburetor kumatsimikizira kuchuluka kwa mafuta a mpweya omwe injini idzalandira.Kuti zimenezi zisamayende bwino, pamakhala mbale yozungulira yotchedwa throttle, yomwe imakhondekera pakati pa nyanga ya mpweya.
Mukayendetsa chiwongolero (kapena kupondapo gasi m'galimoto) mumayendetsa mbale yozungulira kuti ikhale yoyima kuti mulole kusakanikirana kwakukulu kwa mpweya ndi mpweya.
Ndikofunikiranso kumvetsetsa momwe mafuta amafikira ku carburetor komanso momwe amayendera mu jet.Kwa makina ang'onoang'ono omwe amagwira ntchitozi ndi zigawo zazikulu zosuntha mu carburetor ndipo zimalephera.Zigawozi ziyenera kugwira ntchito moyenera, kapena mwina pali mavuto awiri:
1) Mafuta ochepa amalowa mu silinda, ndipo injini imafa ndi njala ndikuyima.
2) Kapena mafuta ochulukirapo amalowa, zomwe zimapangitsa injini kusefukira ndikuyima.(Kuchuluka koyenera kwa chisakanizo chophulika ndi chopapatiza.)
Tanki yamafuta imasunga mafuta.Ndipo m'mapangidwe osavuta amayikidwa pamwamba pa carburetor ndikulumikizidwa ndi chubu.Mafuta amayenda ndi mphamvu yokoka kuchokera ku thanki kupita ku carburetor, yomwe ili ndi mbale yaying'ono yosungiramo kuti injiniyo isaperekedwe kwa mphindi imodzi.Dongosololi limagwira ntchito bwino kwa makina otchetcha am'nyumba ndi owuzira.
Mapangidwe enanso ofunikira, mwina osavuta kwambiri, ndi choyatsira chonyamula, chowonetsedwa mu 1-19.Carburetor iyi imakhala ndi jeti, singano yosinthika yosinthika yomwe imalowera mkati mwake (kuti asinthe kayendedwe ka mafuta), kugunda, kutsamwitsa, nyanga ya mpweya, ndi mapaipi oyamwa amodzi kapena awiri (“mapaipi akumwa”) omwe amalowa mkati. thanki ya gasi.Mpweya wa nyanga ya mpweya wa carburetor umayamwa udzu kudzera mu jet kupita ku nyanga ya mpweya.
M'ma mowers ambiri ndi zowulutsira, komabe, chakudya champhamvu yokoka sichitheka chifukwa thanki ya gasi silingakwezedwe mokwanira, ndipo kunyamula kosavuta sikumapereka mphamvu yamafuta kuti injini igwire ntchito bwino pa liwiro lililonse. zinthu izi zovuta kupopa mafuta ndi makina metering ntchito.Zonsezi zimamangidwa mu ma carburetor pamainjini ang'onoang'ono omwe mungakhale nawo 011 chotchetcha kapena chowuzira.Mu macheka a unyolo, momveka bwino, mitundu yosiyanasiyana yogwirira ntchito imapangitsa kuti dongosolo la chakudya champhamvu yokoka likhale losathandiza.Ndipo kuti apereke mafuta abwino m'mikhalidwe yonse, kuyimitsa kosavuta sikungakhalenso kwabwino.
Pampu ya pa-carburetor ndi kachidutswa ka pulasitiki kosinthika kamene kamadulidwa ma Hap awiri ooneka ngati C omwe amasunthira mmwamba ndi pansi poyankha kuphulika kwa vacuum mu injini.Amaphimba ndi kuvumbula njira kuchokera ku tanki yamafuta ndi makina operekera mafuta a carburetor, komwe mafuta amayikidwa mu nyanga ya mpweya.M'ma carburetor ena, kuthamanga kwa crankcase ndi vacuum zimangosuntha kachidutswa kakang'ono, komwe kamatsegula ndikukakamiza kutseka kolowera ndi valavu yamtundu wa mpira.Kapangidwe kameneka kamakhala ndi mpira wachitsulo womwe umapangidwa mwapadera kuti ulowe mu ndimeyo.Mpira ukasunthidwa mbali imodzi;imasindikiza njirayo;ikasunthidwa mwanjira ina, mafuta amatha Momwe adadutsa.
Mafuta akakhala mu carburetor, imodzi mwa njira ziwiri imagwiritsidwa ntchito poyang'anira kusungirako ndi metering.Pa makina otchetcha ndi owuzirira ambiri, amagwiritsa ntchito njira yoyandama, mofanana ndi yomwe ili m’thanki yachimbudzi.Monga momwe zasonyezedwera mu L-20, Hoat yokhotakhota yokhala ndi mkono wowonetsera imatsika pamene mlingo wa mafuta mu mbale ya carburetor uli wochepa, kulola singano ya tapered kuchoka pampando wake, ndikutsegula njira yopita ku mbale.Mafuta amalowa bwanji, kupangitsa Kutentha kukwera.Hoat ikafika pamlingo womwe wasankhidwa, imakankhira singano pampando wake, ndikutseka mafuta Momwe.The Hoat imatsimikizira kupezeka kokwanira ndipo ndegeyo imachokera ku mbale ya Hoat yofunikira.
Pa macheka a unyolo Hoat systenl sangagwire ntchito, chifukwa tcheni chimagwiritsidwa ntchito pamakona osiyanasiyana kuti Hoat sangasunge mbale yodzaza bwino nthawi zonse.M'malo mwake, pali mapangidwe a Hoatless omwe amagwiritsidwa ntchito, okhala ndi diaphragm yomwe imasuntha valavu ya singano.Pamene crankcase imapanga vacmmi, imakoka diaphragm ya carburetor;Izi zimapanga vacuum yomwe imakokanso singano pampando wake, kulola mafuta kupita Momwemo kudzera mu jeti kupita ku nyanga ya mpweya, kusakanikirana ndi mpweya wodutsa.Monga tawonera mu L-21, ma diaphragms amatha kugwira ntchito m'njira zambiri.Onaninso l-22 mpaka l-25.
