Isistimu Yenjini Yamafutha Enjini Encane Encane
Injini isebenza ngokuyinhloko emoyeni, cishe izingxenye ezingu-14 zomoya ziye kwenye kaphethiloli.Ngakho-ke, umsebenzi wesistimu kaphethiloli, owokuqala ukuxuba, umoya kanye nophethiloli ngezilinganiso ezifanele bese ukuletha ekamelweni elivuthayo.I-carburetor iyisici esiyinhloko.Ixuba uphethiloli nomoya, kanti kwezinye izinjini ezincane, iphinde ibe nephampu kaphethiloli, edonsa uphethiloli ethangini bese iwahambisa ku-carburetor.
I-carburetor yenjini ejwayelekile iyiklamo elula, elula okungukuthi, uma ujwayele ama-carburetor ezimoto.Uma ukwazile ukuhamba ngendlela yakho ngokusebenzisa injini nokusebenza kwesistimu yokuthungela, noma kunjalo, ungayiqonda i-carburetion futhi.
Qala ngokucabanga nge-atomizer yamakha.Ukhama isibani bese kuphuma isifutho sesiqholo.Uma isitsha sinophethiloli, ubuzothola ingxube yesifutho yomoya namaconsi kaphethiloli.I-atomizer ibukeka ilula, kodwa cishe awuzange ucabange ukuthi isebenza kanjani, ngakho-ke njengenzuzo enqenqemeni yokufunda ngezinjini ezincane zegesi, ungase futhi uqonde le boudoir ebalulekile.
Nge-atomizer, ukukhama isibani kuphoqa umoya ngeshubhu evundlile, ekhonjiswe ku-1-17.Lokhu kudala indawo enengcindezi ephansi phezu kwejethi yeshubhu elixhumayo elidlulela phansi kumakha.Njengoba umoya osebhodleleni le-atomizer ngokwawo umfutho womoya ovamile (amakhilogremu angu-14.7 ngeyintshi yesikwele ngayinye ezingeni lolwandle, kancane kancane endaweni ephakeme kakhulu), uphoqelela amakha ukuba akhuphuke eshubhuni aye engcindezini ephansi.Khona-ke umfudlana womoya uthatha amaconsi bese uwakhipha njengesifutho.
Lokhu empeleni imayelana ne-carburetor.Kodwa esikhundleni seziqholo, indiza yayo ithwala uphethiloli.Esikhundleni sokuphephetha umoya udlule ichopho lendiza ngegilobhu, i-carburetor inosilinda omise okukhethekile okuthiwa i-air horn lapho injini ifaka khona i-vacuum, njengaku-1-18.
Injini enemijikelezo emibili isebenzisa i-vacuum edalwe ku-crankcase lapho ipiston iphakama.Leyo vacuum idonsa ivalve yomhlanga futhi idonse umoya ophondweni lomoya we-carburetor ukuze kwakhiwe indawo enengcindezi ephansi lapho.Njengoba umoya ongaphandle ugijima ugcwalisa indawo engenalutho, udala indawo ekhethekile encane yokucindezela okuphansi eduze kwesihloko sendiza, ukhipha uphethiloli ngendlela yamaconsi
Ingena kuCrankcase
Injini enemijikelezo emine isebenzisa ivacuum edalwe kusilinda lapho ipiston yehla.Esikhundleni sokugeleza ku-crankcase, ingxube yamafutha omoya ingena ngqo kusilinda lapho i-valve yokudonsa ivuleka.Ngaphandle kwalo mehluko, indlela yokuphakela uphethiloli kulezi zinjini ezimbili iyafana.Ukugeleza komoya ku-carburetor kunquma inani lengxube yamafutha omoya injini ezowamukela.Ukuze ulawule lokho kugeleza, kunepuleti eliyindilinga elibizwa ngokuthi i-throttle, elilenga phakathi nendawo yophondo lomoya.
Uma usebenzisa isilawuli se-throttle (noma unyathela i-pedal yegesi emotweni) uzungeza ipuleti eliyindilinga liye endaweni eqondile ukuze uvumele ukugeleza okuphezulu kwengxube yamafutha omoya.
Kubalulekile futhi ukuqonda ukuthi uphethiloli ufika kanjani ku-carburetor nokuthi ubalwa kanjani kujethi.Izindlela ezincane ezenza le misebenzi ziyizingxenye ezibalulekile ezihambayo ku-carburetor futhi zingaphansi kokwehluleka.Lezi zingxenye kufanele zisebenze kahle, noma kungenjalo kuzovela enye yezinkinga ezimbili:
1) Uphethiloli omncane kakhulu uzongena kusilinda, futhi injini izobulawa indlala futhi ima.
2) Noma uphethiloli omningi uzongena, okubangele ukuthi injini igcwale bese ima.(Inani elifanele lengxube eqhumayo likubanga elincane.)
Ithangi likaphethiloli ligcina uphethiloli.Futhi ekusetheni okulula kakhulu kufakwe ngaphezu kwe-carburetor futhi ixhunywe kuyo ngeshubhu.Amafutha ageleza ngamandla adonsela phansi esuka ethangini aye ku-carburetor, enesitsha esincane esingagcina esanele ukugcina injini inikezwa mhlawumbe umzuzu owodwa.Lolu hlelo lusebenza kahle kumamower ohlobo lwasendlini kanye nama-blower.
Omunye umklamo oyisisekelo, mhlawumbe olula kakhulu, i-suction lift carburetor, ekhonjiswe ku-1-19.Le carburetor iqukethe ijethi, inaliti ecibilikayo eshintshashintshayo exhuma kuyo (ukulungisa ukugeleza kukaphethiloli), i-throttle, ukuklinywa, uphondo lomoya, kanye nepayipi elilodwa noma amabili okudonsa (“izitsha zokuphuza zikaphethiloli”) ezehlela phansi. ithangi likaphethiloli.I-vacuum ophondweni lomoya we-carburetor lumunca uphethiloli wotshani ngejethi ukuya ophondweni lomoya.
Kodwa-ke, kuma-mowers amaningi nama-blower, amandla adonsela phansi akwenzeki ngoba ithangi legesi alikwazi ukukhwezwa phezulu ngokwanele, futhi i-suction lift elula ayinikezi isilawuli sikaphethiloli ukuze injini isebenze kahle kuzo zonke isivinini. lezi zimo eziyinkimbinkimbi kakhulu zokupompa uphethiloli kanye nezinhlelo zamamitha zisetshenziswa.Zombili lezi zakhiwe kuma-carburetor ezinjinini ezincane okungenzeka ube nazo 011 umshini wokugunda noma i-blower yakho.Ku-chainsaha, ngokusobala, ama-engeli ahlukahlukene okusebenza enza uhlelo lokuphakelayo kwamandla adonsela phansi lungasebenzi.Futhi ukunikeza uphethiloli omuhle ngaphansi kwazo zonke izimo, i-suction lift elula nayo ngeke ibe yinhle kakhulu.
Iphampu ye-on-carburetor ucezu lwepulasitiki oluguquguqukayo okusikwa kulo ama-Hap amabili amise okuka-C ahamba phansi naphezulu ukuphendula ama-vacuum enjinini.Zimboza futhi zembule amaphaseji asuka ethangini likaphethiloli kanye nesistimu yokulethwa kukaphethiloli ye-carburetor, lapho uphethiloli ubalwa ngophondo lomoya.Kwamanye ama-carburetor, ingcindezi ye-crankcase kanye ne-vacuum imane inyakaze i-diaphragm yocezu olulodwa, edonsa ivuleke futhi iphoqelele i-valve yohlobo lwe-outlet ne-outlet evaliwe.Lo mklamo uqukethe ibhola lensimbi elifakwe ephasejini elimise okukhethekile.Uma ibhola ligudluzwa indlela eyodwa;ivala indlela;uma igudluzwa ngenye indlela, uphethiloli ungadlula kanjani.
Uma uphethiloli usukwi-carburetor, enye yezindlela ezimbili isetshenziswa ukulawula isitoreji kanye nemitha.Emashini amaningi okugunda nama- blower, kusetshenziswa uhlelo lokuntanta, olufana nalolo olusohlwini lwethange lendlu yangasese.Njengoba kuboniswe ku-l-20, i-Hoat enehingiwe enengalo evezayo iyehla lapho izinga likaphethiloli endishini ye-carburetor liphansi, livumela inaliti ecijile ukuthi iphume esihlalweni sayo, ivule indlela eya endishini.Uphethiloli ungaphakathi, okwenza Ukushisa kukhuphuke.Uma iHoat ifika ezingeni elimisiwe, iphusha inaliti ibuyele esihlalweni sayo, ivale uphethiloli Kanjani.I-Hoat iqinisekisa ukutholakala okwanele futhi indiza idonsa esitsheni se-Hoat ngokudingekayo.
Kumasaha e-chain i-Hoat systenl ngeke isebenze, ngoba i-chain saw isetshenziswa ema-engeli amaningi ahlukene kangangokuthi iHoat ngeke igcine isitsha sigcwaliswe kahle ngaso sonke isikhathi.Esikhundleni salokho, kunemiklamo ye-Hoatless esetshenziswayo, equkethe i-diaphragm ehambisa i-valve yenaliti ecijile.Lapho i-crankcase idala i-vacmmi, idonsa i-carburetor diaphragm;lokhu kudala i-vacuum ephinde ikhiphe inaliti esihlalweni sayo, ivumele uphethiloli ukuthi udlule kanjani ngendiza iye ophondweni lomoya, uhlangane nomoya oshayayo.Njengoba kukhonjisiwe ku-l-21, ama-diaphragm angasebenza ngezindlela eziningi.Futhi bheka u-l-22 kuye ku-l-25.
