Umsebenzi we-valve yokulawula uwoyela.
Umsebenzi oyinhloko we-valve yokulawula uwoyela ukukhawulela ukucindezela okukhulu kwesistimu yokugcoba ukuvimbela ukucindezela okukhulu ekulimazeni izingxenye zesistimu yokugcoba nokugwema ukuvela kokuvuza kwamafutha. I-valve yokulawula uwoyela iqinisekisa ukusebenza okuvamile kwesistimu yokugcoba injini ngokulungisa ukucindezela kwamafutha. Ivamise ukufakwa kumzila kawoyela ophumayo wephampu kawoyela ukuze uqaphe ngempumelelo futhi ulawule ukucindezelwa kukawoyela. Uma i-valve yokulawula uwoyela ihluleka, ingabangela imoto ukuthi ime ngesikhathi sokushayela, futhi umfutho kawoyela uzokhuphuka ngendlela engavamile, okuzophazamisa ukusebenza okuvamile kwemoto.
Umgomo wokusebenza wevalvu yokulawula uwoyela uhlanganisa ukuhlanganiswa komzimba we-valve kanye nomhlangano we-actuator, okusebenza ndawonye ukuze kuzuzwe ukulawulwa komfutho kawoyela. Ohlelweni lwesikhathi lwe-valve eguquguqukayo, ivalvu yokulawula uwoyela ikhetha amasekhethi kawoyela ahlukene ukuze axhumane nesilawuli se-VVT ngokwemiyalo yokulawula ye-ECU yenjini, ukuze kube kusenesikhathi, kubambezeleke noma kugcinwe lezi zimo ezintathu ezihlukene zokusebenza. Le ndlela yokulawula iqinisekisa ukuthi i-valve iyavuleka futhi ivaleke ngesikhathi esifanele, ngaleyo ndlela ithuthukise ukusebenza kwenjini.
Ngaphezu kwalokho, uwoyela, uwoyela wenjini, udlala indima ebalulekile ekugcotshisweni kwenjini nasekunciphiseni ukugqokwa, ukupholisa okuyisizayo nokupholisa , ukuvimbela ukuvuza kokuvalwa, ukuvimbela ukugqwala nokuvimbela ukugqwala , ukushaqeka njalonjalo. Yaziwa ngokuthi "igazi" lemoto. Umsebenzi wevalvu yokulawula uwoyela ukulawula nokuvimbela umfutho wesistimu yokugcobisa injini ukuthi ungabi phezulu kakhulu ukuvikela injini ekulimaleni.
I-valve yokulawula uwoyela iphukile
Ukusebenza kokwehluleka kwe-valve yokulawula uwoyela ikakhulukazi kuhlanganisa:
Imoto ingase ime kungazelelwe ngesikhathi sokushayela, okubangelwa i-valve yokulawula uwoyela ayikwazi ukulungisa umfutho kawoyela ngendlela evamile, okuholela ekugcobeni kwenjini okwanele.
Umfutho kawoyela uphezulu ngendlela engavamile, uma umfutho kawoyela uphezulu kakhulu, kuzoholela ekuhlanganiseni okukhulu kakhulu, intuthu emnyama evela epayipini le-exhaust, namandla emoto anganele. Ukwengeza, umfutho kawoyela ophakeme kakhulu ungase futhi ubangele umfutho kawoyela ukuba ube phansi kakhulu noma ungakwazi ngisho nokusungula, ngaleyo ndlela kwandise ukusetshenziswa kukaphethiloli.
Amafutha azoshisa, okuzoholela ekusetshenzisweni kukaphethiloli okwenyukayo, ukukhishwa kwegesi ngokweqile, isivinini esingazinzile sokungenzi lutho, ukuthuthukisa izingozi ezifihliwe zemoto nokwandisa umthwalo wezomnotho. Uwoyela ovuthayo uzophinde uholele ekwandeni kwekhabhoni eqoqweni lomlilo wenjini, ukusheshisa okubuthakathaka, isivinini esiphansi, amandla anganele kanye neminye imiphumela emibi.
Ukulimala kwevalvu yokulawula uwoyela kubangele ukuzamazama kwenjini, ukukhanya kokwehluleka kukhanyise. Ikhodi yephutha okukhiphayo ingase ibe isifunda esivulekile se-valve ye-solenoid yokulawula i-VVT, isifunda esifushane phansi, noma isifunda esifushane ku-electrode enhle. Ngaphansi kwezimo ezijwayelekile, i-voltage waveform yetheminali kufanele ibe isignali ye-pulse enkulu kakhulu kunesiginali evumayo, futhi uma i-waveform ingalungile, izobangela ukwehluleka kwenjini.
Ngakho-ke, uma umonakalo we-valve yokulawula uwoyela usutholakele, kufanele uphathwe ngokushesha ukuze ugweme imiphumela emibi kakhulu.
Ivalvu yokulawula uwoyela iphuka muphi umphumela emotweni
I-valve yokulawula uwoyela ephukile ingaholela ochungechungeni lwemiphumela emibi, okuhlanganisa ukushiswa kwamafutha, ukwanda kokusetshenziswa kukaphethiloli, ukukhishwa kwe-exhaust ngokweqile, isivinini sokungenzi lutho esingazinzile, namandla anganele.
Ukushiswa kukawoyela: Ukwehluleka kwevalvu yokulawula uwoyela kuzoholela ekushisweni kukawoyela, okuzobangela ukugcwala kwenjini okunganele, kubhebhethekise ukuguga kwenjini, ngisho nokwehluleka.
Ukwenyuka kokusetshenziswa kukaphethiloli: Ukushiswa kukawoyela kuzoholela ekwenyukeni kokusetshenziswa kukaphethiloli wenjini, okuzokwandisa ukusetshenziswa kukaphethiloli wemoto.
Ukukhishwa kwegesi ngokweqile: ukushiswa kukawoyela kuzoholela ekukhishweni kwegesi ngokweqile, okubangela ukungcoliswa kwemvelo.
Ukungaqini kahle kwe-idling: Ukwehluleka kwevalvu yokulawula uwoyela kuzoholela ekungaqini kahle kwenjini, imoto izozamazama nezinye izinto lapho ushayela.
Amandla anganele: Ukwehluleka kwe-valve yokulawula uwoyela kuzoholela emandleni enjini anganele, futhi kuzoba nezinkinga ezifana nokusheshisa okubuthakathaka lapho imoto ishayela.
Imoto ingase ime: Uma i-valve yokulawula uwoyela iphukile, imoto ingase ime ngenkathi ishayela.
Ukwenyuka kwekhabhoni yegumbi lomlilo wenjini: Ukushisa uwoyela kuzoholela ekwandeni kwekhabhoni yegumbi lomlilo lenjini, ukusheshisa okubuthakathaka, isivinini esincane.
Ukwanda komthwalo wezomnotho: Ukushisa uwoyela kuzokwandisa umthwalo wezomnotho wemoto, ngoba kudingeka izindleko ezengeziwe zikaphethiloli nezokulungisa.
Kuthinta ukusebenza okuvamile kwenjini: i-valve yokulawula uwoyela iphukile, okuzokwenza ukuthi ukucindezela kwesistimu yokugcoba injini kube phezulu kakhulu, ngaleyo ndlela kuthinte ukusebenza okuvamile kwenjini.
Umsebenzi oyinhloko we-valve yokulawula uwoyela ukulawula nokuvimbela ukucindezela kwesistimu yokugcoba injini ukuba ibe phezulu kakhulu. Ngakho-ke, lapho i-valve yokulawula uwoyela ihluleka, idinga ukwelashwa kusenesikhathi ukugwema ukulimala enjinini.
Sicela usishayele uma udinga such imikhiqizo.
