Isebenza njani umsebenzi wokuphelisa umsebenzi?
Umgaqo wokuSebenza womlawuli weSigaba sokuphelisa ikakhulu ikakhulu kukufakelwa kwentwasahlobo yentwasahlobo, isikhokelo se-torque siphikisana ne-torique sangaphambili seCamshaft, ukuqinisekisa ukuba uMlawuli weSigaba sokuSebenzisa unokubuya rhoqo. Ukusebenza kwe-injini, ngokutshintsha okuqhubekayo kwemeko yokusebenza, inqanaba leCamshaft kufuneka lihlengahlengiswe ngokuqhubekayo, kwaye intwasahlobo ibuyise ijikeleze ngokuchaseneyo nohlengahlengiso lwesigaba. Le ntshukumo inokukhokelela ekutyeshekeni kwentwasahlobo yentwasahlobo, ke iyimfuneko ukuvavanya eyona nto iphambili eveliswe yintwasahlobo yentwasahlobo xa usebenza ukhuseleko lwentwasahlobo.
Umgaqo wokuSebenza owenziwayo weSigaba sokuphelisa iSigaba sokuphelisa ukwabandakanya inqaku lesigaba se-Injini, oko kukuthi, ixesha lokuvula kunye nokuvala kunye nexesha lokuvula kunye nokuvula i-inlet kunye neevalves ze-inlet kunye ne-valves ezifanekiwe yi-crankseshaft engle. The valve phase is usually represented by a circular diagram of the crank Angle relative to the top and bottom dead center crank positions, which can be seen as the process of inhaling and exhaling the human body. Umsebenzi ophambili wendlela ye-valve kukuvula kwaye uvale i-inlet kunye ne-valves ye-cllind nganye ngokwexesha elithile, ukuze uqonde yonke inkqubo yokunikezelwa kwe-injini.
Kwizicelo ezithile zobugcisa ezingakumbi, ezinjengetekhnoloji ye-VTEC, ngokulungelelanisa ukutshintshwa kwenkqubo yolawulo lwe-elektroniki, kungakwazi ukutshintshelwa kwe-carve ezihamba ngesantya esiphezulu kunye nesantya esiphezulu, ukuze siziqhelanise neemfuno ze-enjini yokusebenza. Umgaqo wokuSebenza ye-VTEC kukuba xa i-injini iguqulwa kwisantya esincinci ukuya kwisantya esiphezulu, ikhompyutheni ye-elektroniki ngokuchanekayo ngokujikeleza i-tudrine, kwaye iqhubela phambili kwi-tudrine encinci yokufezekisa ixesha lokuhlengahlengiswa kwe-valve. Le teknoloji iphucula ngokufanelekileyo ukusebenza ngempumelelo, ukunyusa iziphumo zamandla, kwaye kuncitshiswe ukusetyenziswa kwamafutha kunye nokukhupha.
Ithini indima yomlawuli wokuphelisa iSigaba?
Owona msebenzi ophambili kumlawuli wokuphelisa umlawuli kukulungelelanisa isigaba seCamshaft ngokweenguqu kwiimeko zokusebenza, ukuze uhlengahlengise i-injini yokufumana i-injini, kwaye uphucule ukusebenza ngempumelelo kwe-injini, kwaye unyuse amandla enjini.
UMlawuli weSigaba sokuSebenzisa uphume kwimpumelelo ye-injini ngomgaqo wayo wokusebenza. Isicelo esisebenzayo, xa i-injini ivaliwe, uMlawuli weSigaba seSigaba seSigaba esimnandi, kwaye uMlawuli weSigaba sokuphelisa ukwisikhundla esiphezulu. I-injini yaseCamshaft ijikeleza kwicala le-lag phantsi kwesenzo sokuthengisa i-Torque. NgoMlawuli weSigaba sokuphelisa, isikhundla sayo sokuqala sikwindawo ephezulu kakhulu, ngoko ke i-camshaft tourque kufuneka yoyiswe ukuba ibuyele kwindawo yokuqala xa injini imisiwe. Ukwenzela ukuba uMlawuli weSigaba sokuSebenzisa ukubuyela ngesiqhelo, intwasahlobo ibuyiselwa kuyo, kwaye isikhokelo sayo seTyque siphikisana nesikhokelo se-camshaft. Xa i-injini iyasebenza, ngokutshintsha okuqhubekayo kwemeko yokusebenza, inqanaba leCamshaft kufuneka lihlengahlengiswe ngokuqhubekayo, kwaye intwasahlobo ibuyela ngokuchaseneyo nohlengahlengiso lwesigaba. Lo msebenzi unceda ukukhetha ukusebenza kwe-iji, kubandakanya namandla, itota kwaye inciphise ukukhutshwa okuyingozi.
Ukongeza, uyilo kunye nokusetyenziswa kwee-subergans zoMlawuli weSigaba sokuSebenzisayo nako kubandakanya ukuthotyelwa kwemigaqo ye-Injini yokuphuma. Umlawuli weSigaba seCamshaft usetyenziswe ngokubanzi kwi-injini ye-petroli kunye nommiselo oqingqiweyo wemoto yokuphuma kwemoto. Ngokuhlengahlengiswa ngokuqhubekayo i-valve ngaphezulu kwe-vallap, umlawuli weSigaba seCamshaft unokutshintsha kwaye alawule ngempumelelo igesi yokunyuka kwamaxabiso e-injini, ngaloo ndlela ukuphuculwa kwe-injini yokusebenza.
