Usebenza njani umlomo wemoto
Umgaqo wokusebenza wenozzle yenaliti yamafutha emoto usekwe ikakhulu kwindlela yokulawula i-electromagnetic. Xa iyunithi yolawulo lwe-injini (ECU) inika umyalelo, ikhoyili esemlonyeni idala indawo enemagnethi, ethi itsalele phezulu kwivalve yenaliti kwaye ivumele ukuba kutshizwe amafutha ngombhobho. Emva kokuba i-ECU iyeke ukubonelela amandla kunye nentsimi yamagnetic iyanyamalala, i-valve yenaliti ivalwe kwakhona phantsi kwesenzo se-spring spring, kwaye inkqubo yokujova i-fuel iphelile.
Indlela yokulawula i-electromagnetic
Umbhobho wamafutha ulawulwa ngumgaqo we-electromagnetic. Ngokukodwa, xa i-ECU inika umyalelo, i-coil kwi-nozzle ivelisa intsimi yamagnetic, idonsa i-valve yenaliti, kwaye i-fuel ifafazwe nge-nozzle. Emva kokuba i-ECU iyeke ukunikezelwa kwamandla, i-magnetic field iyanyamalala, i-valve yenaliti ivaliwe phantsi kwesenzo se-spring spring, kwaye inkqubo ye-oil injection iphelile.
Inkqubo yokutofa amafutha
I-fuel nozzle i-atomize amafutha kuxinzelelo oluphezulu kwaye itshize ngokuchanekileyo kwi-cylinder ye-injini. Ngokweendlela zokutofa ezahlukeneyo, inokwahlulwa ibe yinaliti yombane enenqaku elinye kunye nenaliti yombane enamanqaku amaninzi. I-EFI ye-single-point yenzelwe ukunyusa i-injector kwindawo ye-carburetor, ngelixa i-EFI ye-multi-point ifakela i-injector enye kumbhobho wokungena we-cylinder nganye yokulawulwa kwe-injection ye-finer fuel.
Umbhobho wemoto, okwaziwa ngokuba yinaliti yesibaso, yinxalenye ebalulekileyo yenkqubo yokutofa kwe-injini yemoto. Umsebenzi wayo ophambili kukufaka i-petroli kwi-cylinder, ukuyixuba nomoya kwaye uyitshise ukuvelisa amandla. Isitofu se-fuel nozzle siqinisekisa ukusebenza okuqhelekileyo kwe-injini ngokulawula ixesha kunye nobungakanani benaliti yeoli. ...
Umgaqo wokusebenza we-nozzle uphunyezwa nge-valve ye-solenoid. Xa i-coil ye-electromagnetic yenziwe amandla, ukufunxa kuveliswa, ivalve yenaliti ifunxiwe, umngxuma wokutshiza uyavulwa, kwaye i-fuel itshizwe ngesantya esiphezulu kwisithuba se-annular phakathi kwenaliti ye-shaft kunye nomngxuma wokutshiza kwintloko yevalve yenaliti, eyenza inkungu, evumela ukuvutha ngokupheleleyo. Umthamo wenaliti yepetroli yombhobho wenaliti yamafutha ngumba obalulekileyo wokumisela umlinganiselo wamafutha omoya we-injini yemoto. Ukuba umbhobho wenaliti yamafutha uvalwe kukwanda kwekhabhoni, oko kuya kukhokelela kwijitha ye-injini kunye nokungonelanga kwamandla okuqhuba.
Ngoko ke, kuyimfuneko ukucoca umlomo rhoqo. Kwiimeko eziqhelekileyo, kucetyiswa ukuba kwimeko yesimo esihle sesithuthi kunye nekhwalithi ye-oyile efanelekileyo, i-oil nozzle kufuneka ihlambuluke yonke i-40,000-60,000 yeekhilomitha. Ukuba umbhobho wokutofa ufunyaniswe uvalekile, kufuneka ucocwe kwangethuba ukuthintela umonakalo omkhulu ngakumbi kwi-injini.
