Ngabe uchungechunge lwezikhathi lusebenza kanjani?
Uchungechunge lwakho lwezikhathi lubaluleke kakhulu ekusebenzeni kwemoto yakho. Uma iphuka, imoto yakho ngeke iye ndawo futhi ungalimaza injini. Ngakho-ke, uchungechunge lwezikhathi lusebenza kanjani, futhi kwenzekani uma...
Uchungechunge lwakho lwezikhathi lubaluleke kakhulu ekusebenzeni kwemoto yakho. Uma iphuka, imoto yakho ngeke iye ndawo futhi ungalimaza injini. Ngakho-ke, uchungechunge lwezikhathi lusebenza kanjani futhi kwenzekani uma lwehluleka?
Okuyisisekelo
Zonke izinjini ze-piston zine-crankshaft kanye ne-camshaft. Ama-pistons aya phezulu naphansi, futhi i-crankshaft idlulisela amandla kuwo futhi iguqule lawo mandla abe ukunyakaza okujikelezayo. I-crankshaft bese ishayela i-camshaft ngeketango. Ngakolunye uhlangothi lwe-crankshaft kukhona ukudluliselwa, okubhekene nokushayela amasondo akho. I-camshaft ivula futhi ivale ama-valve okungenisa nawokukhipha. Ngesilinda ngasinye senjini, i-camshaft ivula i-valve yokungenisa, ivumela ingxube yomoya nophethiloli. Ibese ivula i-valve yokukhipha umoya ukuze kudedelwe amagesi kaphethiloli ashile. Amavalvu kufanele avuleke futhi avale ngezikhathi ezifanele. Le nqubo yaziwa ngokuthi isikhathi se-camshaft noma isikhathi se-valve.
Izindlela Zokuvumelanisa
Kunezindlela ezimbili zokufinyelela isikhathi se-valve. Eyokuqala iyindlela yamagiya amabili, futhi iyona ethembeke kakhulu. Igiya le-crankshaft livele lizibandakanye negiya le-camshaft. Lamagiya cishe awapheli futhi ajwayele ukusebenza kahle empilweni yenjini. Le ndlela isetshenziswa ezinhlotsheni eziningi zemishini esindayo namaloli amakhulu. Ibuye isetshenziswe kwezinye izimoto.
Indlela ye-timing chain ivame kakhulu ezimotweni, ikakhulukazi zeminyaka ethile. Izimoto eziningi zesimanje zifakelwe amabhande e-timing, nakuba ezinye zisenama-timing chain. Uchungechunge lwesikhathi lunganwebeka, olungathinta ukusebenza. Ukwengeza, ezinye izimoto zine-plastic camshaft sprockets ezingancibilika uma zishiswa ngokweqile. Khona-ke iketango liyeqa futhi injini iyama. Uma i-piston iphakama ngesikhathi esifanayo lapho i-valve ivuliwe ngokugcwele, i-valve ingase igobe futhi injini ingase ihluleke.
Ukunquma uchungechunge lwesikhathi olunephutha
Ngokuvamile uzoqaphela ezinye izimpawu ngaphambi kokuba uhlangane neketango lesikhathi eliphukile. Isignali ejwayeleke kakhulu umsindo okhencezayo ovela ngaphambili enjini, ikakhulukazi uma ishaya kancane. Izingcezu zepulasitiki emafutheni zingolunye uphawu lokuthi uchungechunge lwakho lwesikhathi lungase ludinge ukushintshwa. Uma uthola ipulasitiki emafutheni ngemuva kokushintshwa kwamafutha, i-cam sprocket cishe isilungele ukwehluleka. Uma lokhu kwenzeka, lezi zingcezu zingangena esikrinini sepompo likawoyela, okubangele ukuba imoto ilahlekelwe umfutho kawoyela. Futhi uma ingcindezi iba phansi kakhulu, ukwehluleka kochungechunge lwesikhathi cishe akunakugwenywa.
Into yokugcina oyifunayo ukuthi i-timing chain yakho ingaphumeleli ngoba ingadala umonakalo omkhulu enjinini yakho futhi kwesinye isikhathi iphinde iyibhubhise. Ngakho-ke qiniseka ukuthi uchungechunge lwakho lwesikhathi lusesimweni esihle, lalela futhi ubheke amacebo okuthi izinto zingase zingabi ngendlela okufanele zibe ngayo, bese ucela umakhenikha wakho ukuthi alishintshe uma kunesidingo.
