Ubungakanani obuncinci beSixokelelwano se-Fuel injini yepetroli
I-injini isebenza kakhulu emoyeni, malunga neendawo ezili-14 zomoya ukuya kwenye yepetroli.Umsebenzi wenkqubo yamafutha, ngoko ke, kukuqala ukuxuba, umoya kunye nepetroli ngokwemilinganiselo efanelekileyo kwaye emva koko uyihambise kwigumbi lokutshisa.I-carburetor yinxalenye ephambili.Ixuba i-fuel kunye nomoya, kwaye kwezinye iinjini ezincinci, iphinda ifake ipompo ye-fuel, ekhupha i-fuel kwi-tank kwaye inikezele kwi-carburetor.
I-injini encinci ye-carburetor yoyilo olulula, olula oko kukuthi, ukuba uqhele i-carburetors yeemoto.Ukuba ukwazile ukuhamba ngendlela yakho nge-injini kunye nokusebenza kwenkqubo yokutshisa, nangona kunjalo, unokuqonda i-carburetion nayo.
Qala ngokucinga ngeatomizer yesiqholo.Ukhama ibhalbhu kwaye kuphume isitshizi sesiqholo.Ukuba isitya sinepetroli, uya kufumana umxube wokutshiza womoya namathontsi epetroli.I-atomizer ibonakala ilula, kodwa mhlawumbi awuzange ucinge malunga nendlela esebenza ngayo, ngoko njengenzuzo yokufunda malunga neenjini zegesi ezincinci, unokuyiqonda le boudoir ebalulekileyo.
Nge-atomizer, ukucudisa ibhalbhu kunyanzela umoya ngombhobho othe tye, oboniswe kwi-1-17.Oku kudala indawo yoxinzelelo oluphantsi phezu kwejethi yetyhubhu edibanisayo eya ezantsi kwisiqholo.Kuba umoya okwibhotile yeatomizer ngokwawo ukuxinzelelo lomoya oluqhelekileyo (14.7 pounds per square intshi kumphakamo wolwandle, kancinci kancinci kwindawo ephezulu), inyanzela isiqholo sinyuse ityhubhu ukuya kuxinzelelo olusezantsi.Emva koko umsinga womoya uthabatha amathontsi uze uwakhuphe njengesitshizi.
Le yeyona nto imalunga ne-carburetor.Kodwa endaweni yesiqholo, ijethi yayo ithwala ipetroli.Kunokuba ivuthele umoya udlule kwincam yejethi ngeglowubhu, i-carburetor inombhobho owenziwe ngokukhethekileyo obizwa ngokuba luphondo lomoya apho injini ifaka ivacuum, njengaku-1-18.
Injini yemijikelo emibini isebenzisa ivacuum eyenziwe kwikhrankcase xa ipiston iphakama.Olo vacuum lutsala luvule ivalve yengcongolo kwaye lutsale umoya ovela kwiphondo lomoya le-carburetor ukwenza indawo yoxinzelelo oluphantsi apho.Njengoko umoya wangaphandle ugxalathelana ukuzalisa ivacuum, idala indawo ekhethekileyo yoxinzelelo olusezantsi olujikeleze incam yejethi, ikhupha amafutha ngendlela yamathontsi athe wona.
Iqhubela kwiCrankcase
I-injini ye-four-cycle isebenzisa i-vacuum eyenziwe kwi-cylinder xa ipiston isihla.Endaweni yokuba uqukuqelele kwikhrankcase, umxube wamafutha omoya uya ngqo kwi-cylinder xa ivalve yokungena ivula.Ngaphandle kolu mahluko, indlela yokubonelela ngesibaso kwezi njini zimbini iyafana.Ukuhamba komoya kwi-carburetor kugqiba inani lomxube we-air-fuel injini eya kuyifumana.Ukulawula oko kuqukuqela, kukho ipleyiti esazinge ebizwa ngokuba yi-throttle, ejinga kumbindi wephondo lomoya.
Xa usebenzisa i-throttle control (okanye unyathela kwipedali yerhasi emotweni) ujikela ipleyiti esetyhula kwindawo ethe nkqo ukuvumela ukuhamba komxube wamafutha omoya aphezulu.
Kwakhona kubalulekile ukuqonda indlela amafutha afika ngayo kwi-carburetor kunye nokuba ibalwa njani kwijethi.Iindlela ezincinci ezenza le misebenzi zingundoqo ezihamba phambili kwi-carburetor kwaye ziphantsi kokusilela.La malungu kufuneka asebenze ngokufanelekileyo, okanye mhlawumbi enye yeengxaki ezimbini iya kwenzeka:
I-1)I-fuel encinci kakhulu iya kungena kwi-cylinder, kwaye injini iya kulamba kwaye ime.
2) Okanye amafutha amaninzi kakhulu aya kungena, abangele ukuba injini iphuphume kwaye emva koko ima.(Ixabiso elifanelekileyo lomxube oqhumayo likuluhlu olumxinwa.)
Iitanki yamafutha yindlu yepetroli.Kwaye kwi-setups elula ifakwe ngaphezu kwe-carburetor kwaye ixhunywe kuyo ngombhobho.Amafutha aqukuqela ngomxhuzulane ukusuka kwitanki ukuya kwi-carburetor, enesitya esincinci sokugcina ngokwaneleyo ukugcina injini inikezelwe mhlawumbi umzuzu.Le nkqubo isebenza kakuhle kwiimowers zodidi lwasekhaya kunye nee blowers.
Olunye uyilo olusisiseko, mhlawumbi olulula, luyi-suction lift carburetor, eboniswe kwi-1-19.Le carburetor iquka ijethi, inaliti elungelelanisiweyo ephothiweyo ephosela kuyo (ukulungelelanisa ukuhamba kwepetroli), ikhephu, ukukrwitsha, iphondo lomoya, kunye nombhobho wokufunxa omnye okanye emibini (“iindiza ‘zokusela”) eziphumela ezantsi ukuya kutsho. itanki yerhasi.Ivacuum ekwiphondo lomoya le-carburetor ifunxa amafutha endiza ngejethi ukuya kwiphondo lomoya.
Kwiimowers ezininzi kunye nezivuthela, nangona kunjalo, ukutya kwe-gravity akunakwenzeka ngenxa yokuba itanki yegesi ayikwazi ukunyuswa ngokwaneleyo, kwaye ukunyuswa okulula akuboneleli kulawulo lwamafutha ukuze injini isebenze kakuhle kuzo zonke izantya. ezi meko zinzima ngakumbi zokumpompa amafutha kunye neenkqubo zokubala zisetyenziswa.Ezi zombini zakhiwe kwii-carburetors kwii-injini ezincinci onokuthi ube nazo 011 umatshini wakho wokugunda okanye i-blower.Kwisarha yekhonkco, ngokucacileyo, ii-engile ezahlukeneyo zokusebenza zenza inkqubo yokutya yomxhuzulane ingasebenzi.Kwaye ukubonelela ngesibaso esilungileyo phantsi kwazo zonke iimeko, ukunyuswa kokufunxa okulula akunakuba kuhle kakhulu.
Impompo ye-on-carburetor liqhekeza leplastiki elibhetyebhetye ekusikwe kuyo iiHaps ezimbini ezinobume be-C ezihamba zinyuka zisihla ngokuphendula kukubetha kwevacuum enjinini.Bagquma kwaye batyhile iipaseji kwitanki yamafutha kunye nenkqubo yokuhanjiswa kwepetroli ye-carburetor, apho i-fuel ibalwa kwiphondo lomoya.Kwezinye i-carburetors, uxinzelelo lwecrankcase kunye ne-vacuum zihambisa nje i-diaphragm eneqhekeza elinye, elitsala livuleke kwaye linyanzelise ukuvala ukungena kunye nevalve yohlobo lwebhola.Olu lwakhiwo lubandakanya ibhola yentsimbi kwi-fit-shaped-shaped-threaded threaded in the passage.Xa ibhola ishukunyiswa kwicala elinye;itywina isithuba;xa ishukunyiswa ngenye indlela, isibaso sinokudlula njani.
Emva kokuba i-fuel ikwi-carburetor, enye yeendlela ezimbini zisetyenziselwa ukulawula ukugcinwa kunye nokulinganisa.Kwinkoliso yeematshini zokucheba nezokuvuthela, kusetyenziswa inkqubo yokudada edadayo, kanye njengaleyo idweliswe kwitanki yendlu yangasese.Njengoko kubonisiwe kwi-l-20, i-Hoat ene-hinged ene-projecting arm yehla xa inqanaba le-fuel kwisitya se-carburetor liphantsi, livumela inaliti ene-tapered ukuba iphume esihlalweni sayo, ivule indlela eya kwisitya.Isibaso singena njani, sibangela ukuba uBushushu bunyuke.Xa iHoat ifikelela kwinqanaba elichongiweyo, ityhala inaliti emva kwesitulo sayo, ivala amafutha Indlela.I-Hoat iqinisekisa ukubonelela okwaneleyo kwaye ijethi itsalwa kwisitya seHoat ngokuyimfuneko.
Kwi-chainsaws ye-Hoat systenl ayiyi kusebenza, kuba i-chain saw isetyenziswe kwii-angles ezininzi ezahlukeneyo kangangokuba iHoat ayiyi kugcina isitya sizaliswe ngokufanelekileyo ngamaxesha onke.Endaweni yoko, kukho uyilo lwe-Hoatless olusebenzayo, olune-diaphragm ehambisa ivalve yenaliti ene tapered.Xa i-crankcase idala i-vacmmi, idonsa i-carburetor diaphragm;oku kudala ivacuum ephinda itsale inaliti kwisitulo sayo, ivumela isibaso ukuba Indlela ngejethi ukuya kuphondo lomoya, ukuxubana nomoya ohlaselayo.Njengoko kubonisiwe kwi-l-21, i-diaphragms inokusebenza ngeendlela ezininzi.Kwakhona bona u-l-22 ukuya ku-l-25.
