Ukuqapha Ukuqina Kwenjini: Ukuhlaziywa Komsebenzi Nephutha Kwevalvu Yokulawula Uwoyela Wenjini
Ohlelweni lokusebenza olunembile lwenjini yemoto, yize ivalvu yokulawula uwoyela wenjini ingase ibonakale ingabalulekile, ingenye yezingxenye eziyinhloko eziqinisekisa ukusebenza okuvamile kwenjini. Ifana "nomphathi wokucindezela" wenjini, elawula buthule ukucindezela uwoyela kohlelo lokugcoba futhi ibeka isisekelo esiqinile sokusebenza kahle kwenjini. Uma yehluleka, ngeke nje ithinte ukusebenza kwemoto kodwa futhi ingabangela umonakalo ongenakulungiseka enjinini.
I-Valve Yokulawula Uwoyela Wenjini: "Umlawuli Wokucindezela" Wesistimu Yokugcoba Injini
I-valve yokulawula uwoyela wenjini, eyaziwa nangokuthi i-valve yokulawula ukucindezela uwoyela wenjini, umthwalo wayo oyinhloko ukulawula ngokunembile ukucindezela uwoyela wesistimu yokugcoba injini, ukuqinisekisa ukuthi ingxenye ngayinye yokugcoba ingathola ukuhlinzekwa okufanele kwamafutha enjini. Ngesikhathi sokusebenza kwenjini, iphampu kawoyela izocindezela uwoyela wenjini futhi iyilethe ezingxenyeni ezahlukene zokungqubuzana, kuyilapho i-valve yokulawula uwoyela wenjini isebenza njenge-valve ehlakaniphile, iqapha njalo izinguquko zokucindezela uwoyela: lapho ukucindezela uwoyela kuphezulu kakhulu, ivula isiteshi ukuze ivumele amanye amafutha enjini ukuthi ageleze abuyele ephampu kawoyela ukuze kugwenywe ukulimala kwezingxenye zendlela kawoyela ngenxa yokucindezela okukhulu; lapho ukucindezela uwoyela kuphansi kakhulu, ivala isiteshi sokubuya, igcina ukucindezela uwoyela okudingekayo ukuqinisekisa izidingo zokugcoba zengxenye ngayinye yenjini.
Ngaphezu kokulawula ingcindezi kawoyela, ivalvu yokulawula uwoyela wenjini idlala indima eningi ekusebenzeni kahle kwenjini. Ingavimbela ingcindezi enkulu ohlelweni lokugcoba, igweme ukuvuza kukawoyela noma ukulimala kwezingxenye. Kuhlelo lwesikhathi esiguquguqukayo, ivalvu yokulawula uwoyela wenjini ingalungisa ngokuhlakanipha ngokwejubane lenjini kanye nokuvulwa kwe-throttle, iqinisekise ukuthi injini ingafinyelela ukungena kahle kanye nokukhipha umoya ngesivinini esiphezulu nesiphansi, ithuthukise ukusebenza kwamandla kanye nokonga uphethiloli. Ngaphezu kwalokho, ingcindezi kawoyela ezinzile inganciphisa ukungqubuzana kwangaphakathi enjinini, inciphise ukusetshenziswa kukaphethiloli, futhi ithuthukise ngokungaqondile ukusebenza kahle kwemoto.
Ukwenzeka Kwephutha: Ukubonakaliswa Okuvamile Kokwehluleka Kwevalvu Yokulawula Uwoyela Wenjini
Uma i-valve yokulawula uwoyela wenjini yehluleka, izobangela uchungechunge lwezimpikiswano zamaketanga, okuthinta ngqo ukusebenza okuvamile kwenjini. Izimpawu ezivamile zamaphutha zifaka phakathi lezi zinhlobo ezilandelayo:
Umfutho Kawoyela Ongajwayelekile kanye Nokwehla Kwamandla Lapho umfutho kawoyela uphezulu kakhulu, uzokwenza ingxube ibe nothile kakhulu, intuthu emnyama iphume epayipini lokukhipha umoya, kanye namandla enjini ehle kakhulu. Ezimweni ezimbi kakhulu, ingase yehluleke ngisho nokuthola umfutho kawoyela ojwayelekile. Lapho umfutho kawoyela uphansi kakhulu, uzobangela ukugcotshwa kwenjini okunganele, ukwanda kokungqubuzana kwangaphakathi, okungeke nje kwandise umsindo wenjini kodwa futhi kuzoholela ekunciphiseni kwamandla, ukusheshisa okubi, ngisho nokuvala injini ngokuzumayo ngesikhathi sokushayela.
Ukusetshenziswa Kawoyela Okungajwayelekile kanye Nomonakalo Wezingxenye Amaphutha ku-valve yokulawula uwoyela wenjini azobangela ukungalingani ekuhlinzekweni kukawoyela, okuholela ekwandeni kokusetshenziswa kukawoyela okungavamile, okungagcini nje ngokwandisa izindleko zemoto kodwa futhi okungase kubangele ukusha kukawoyela wenjini. Ukusetshenziswa kukawoyela okungavamile isikhathi eside kuzolimaza nenzwa yomoya-mpilo, okubangela ukuthi ingasebenzi kahle ngaphambi kwesikhathi futhi kuthinte ukuqapha ukukhishwa kwenjini, okuholela ekukhishweni komoya-mpilo okungaphezu kwesilinganiso.
Isexwayiso Sezinsimbi Nobunzima Bokuqala Uma ingcindezi kawoyela ihlala ingajwayelekile, isibani sesixwayiso sengcindezi kawoyela kudeshibhodi yemoto sizokhanya, sixwayise umshayeli ukuthi ahlole isikhathi. Ezinye izimoto zingase zibe nobunzima bokuqalisa, noma ngabe iqala, injini ingase icime ngokushesha futhi yehluleke ukusebenza ngendlela evamile.
Ukuvimbela Izinkinga Ngaphambi Kokuthi Zenzeke: Ukugcinwa Nokusabela Kwephutha Kwevalvu Yokulawula Uwoyela Wenjini
Ukuze kugwenywe ukulahlekelwa okubangelwa ukwehluleka kwevalvu yokulawula uwoyela wenjini, ukulungiswa njalo nokulungiswa ngesikhathi kubalulekile. Abanikazi kufanele bahlole njalo isimo sokusebenza kwevalvu yokulawula uwoyela wenjini, besebenzisa imishini yobungcweti ukuthola ukuthi ingcindezi kawoyela ingaphakathi kwesilinganiso esijwayelekile, futhi banake nokubuka izimpawu ezingavamile ngesikhathi sokusebenza kwemoto.
Ngokuphathelene nokutholakala kwamaphutha, uma ingcindezi kawoyela ingajwayelekile, isinyathelo sokuqala kufanele kube ukuhlola ukuthi ipulaki yevalvu yokulawula uwoyela wenjini iqinile yini, ukuthi kukhona ukugqwala noma ukuguquka, futhi kuhlolwe nokunikezwa kwamandla kagesi kwevalvu kagesi ukuqinisekisa ukuthi ijwayelekile (ngaphezu kwama-volts angu-12), ukuze kunqunywe ukuthi kungenzeka yini ukuthi isekethe inqamuke noma ivuleke. Uma ivalvu yokulawula uwoyela wenjini iqinisekisiwe ukuthi yonakele, kufanele ithathelwe indawo izingxenye zasefektri zokuqala ukuze kugwenywe amaphutha esibili abangelwa ukusebenzisa izingxenye ezingaphansi.
Ngaphezu kwalokho, ukusebenzisa uwoyela wenjini osezingeni eliphezulu nokushintsha njalo isihlungi samafutha kunganciphisa ukuguguleka kwevalvu yokulawula uwoyela wenjini ngenxa yokungcola, kwandise impilo yayo yokusebenza. Kumavalvu okulawula uwoyela avinjiwe ngama-carbon deposits noma ukungcola, ukuhlanza kobungcweti kungenziwa kusetshenziswa imishini yokuhlanza ye-ultrasonic. Amagagasi omthelela kanye nama-micro jets kungahlanza ngokuphelele ama-pores amancane kanye nemifantu, kubuyisele imisebenzi yawo evamile. Isiphetho
Nakuba ivalvu yokulawula uwoyela incane, iyisikhungo esiyinhloko sohlelo lokugcoba lwenjini. Ukusebenza kwayo okuzinzile kuthinta ngqo isikhathi sokuphila kwenjini kanye nokusebenza kwemoto. Njengomnikazi wemoto, umuntu akufanele nje aqonde indima yayo ebalulekile kodwa futhi kufanele aqaphele izimpawu zamaphutha angaba khona. Ngokulungiswa njalo nokulungiswa ngesikhathi, vumela lo "mphathi wokucindezela" ahlale esesimweni esihle kakhulu, eqinisekisa ukusebenza kahle kwenjini.
