I-SOHC (i-camshaft enye ye-injini) ayifane isetyenziswe kwiimodeli zokusebenza eziqhelekileyo zokufuduka kwimarike, kuba isantya esisetyenziswa ngokuqhelekileyo sezithuthuthu siphezulu.

Ulwakhiwo lwe-SOHC lulula kunelo lwe-DOHC, kodwa nangona ine-camshaft enye kuphela, kufuneka idluliselwe kwiivalvu ezine ngeengalo ezimbini ze-valve rocker ukulawula ukuvulwa kunye nokuvala iivalve.

inzuzo:

Ngenxa yokuba kukho i-camshaft enye kuphela, eqhutywa ngokuthe ngqo yi-gear ye-timing, i-injini ayichatshazelwa kancinci kukumelana nokujikeleza kwe-camshaft xa isantya sinyuka, kwaye inokugqiba ukukhutshwa kwenxalenye yesantya esiphantsi ngokukhawuleza.Iindleko zokuyilungisa ziphantsi, isakhiwo silula, kwaye amafutha anoqoqosho kwiindlela ezisetyenziswa ngokuqhelekileyo ezinesantya esiphantsi.

Izinto ezingeloncedo:

Kwizantya eziphezulu, ngenxa yokwaluka kwengalo yevalve rocker, kukho izinto ezininzi ezibuyiselanayo ezivelisa inertia.Ngoko ke, ukulawulwa kwe-valve ngesantya esiphezulu kunokungabikho uzinzo kunye nokuchaneka, kwaye kunokubakho ukungcangcazela okungadingekile okanye ingxolo.

I-DOHC

Njengoko igama lisitsho, i-DOHC ngokwendalo iqhuba ii-camshafts ezimbini.Ngenxa yokuba ii-camshafts ezimbini, i-camshafts inokujikeleza kwaye icinezele i-valve ngokuthe ngqo.Akukho siphakathi sengalo yevalve rocker, kodwa ifuna amatyathanga exesha elide okanye amabhanti ukuqhuba.

inzuzo:

Ukuthetha ngokwesakhiwo, ukuzinza kunye nokuchaneka kwe-ventilation ephezulu yokujikeleza kwe-injini kungcono, okulungele ukwandisa ukusebenza kwe-injini.Ngenxa yokungabikho kwezinto ezininzi eziphindaphindayo kunye nemidiya yokuhambisa, ulawulo lokungcangcazela lungcono.Ukusetyenziswa kweekhamera ezimbini ezizimeleyo kuvumela ukusetyenziswa kwegumbi lokutsha eline-V, kwaye i-angle ye-valve inokuthi iguquguquke ngakumbi ekuyilweni.Iplagi ye-spark inokufakwa kumbindi wegumbi lokutsha, yenza igalelo elithile ekutshiseni ngokupheleleyo okufanayo.

Izinto ezingeloncedo:

Ngenxa yesidingo sokuqhuba iikhamera ezimbini, kuya kubakho ilahleko yetorque kuluhlu lwesantya esisezantsi se-injini.Ngenxa yobume bayo obunzima, iindleko zokugcina kunye nokulungiswa kunye nobunzima buphezulu kunezo ze-SOHC.

Kwii-injini ezinkulu zokufuduswa, uninzi lwee-injini zisebenzisa i-DOHC kuba ulwakhiwo lunokwenza ngcono umgangatho wokuqhuba weenjini ezinkulu zokufuduswa, kunye nokusebenza kwamandla omnye we-injini yokufuduswa komelele, kwaye umlinganiselo welahleko we-torsion ephantsi uya kuba mncinci.

Njengeemoto, ukuba iimoto ezincinci zasekhaya ezineemoto ezincinci zokufuduka zixhotyiswe nge-DOHC, kungcono ukucinezela iindleko kunye nokuphucula ukusebenza kweendleko kunokusebenzisa i-SOHC ngokuzinzileyo ukuphucula amava omsebenzisi.

Nangona kunjalo, kufuneka kugxininiswe ukuba iimoto ze-DOHC azinayo i-torque ephantsi, kwaye iimoto ze-SOHC azinayo i-torque ephantsi eyomeleleyo.Isaxhomekeke kwisethingi yohlengahlengiso lwamanye amacandelo enjini.Izakhiwo ezibini zichaphazela kuphela amandla okusebenza kwenjini kunye noqoqosho lwamafutha kunye nomgangatho phantsi kweemeko ezithile zokusebenza.
