Umsebenzi we-valve yokulawula uwoyela.
Umsebenzi oyinhloko wevalvu yokulawula uwoyela ukukhawulela ingcindezi ephezulu yesistimu yokugcoba ukuvimbela ingcindezi enkulu ekulimazeni izingxenye zesistimu yokugcoba nokugwema ukuvuza kwamafutha. Ivalvu yokulawula uwoyela iqinisekisa ukusebenza okuvamile kwesistimu yokugcoba injini ngokulungisa ingcindezi yamafutha. Ngokuvamile ifakwe ku- isiteshi samafutha esiphumayo sepompo yamafutha ukuze kuqashwe futhi kulawulwe ngempumelelo ingcindezi yamafutha. Uma ivalvu yokulawula uwoyela yehluleka, ingabangela ukuthi imoto ime ngesikhathi sokushayela, futhi ingcindezi yamafutha izokhuphuka ngendlela engavamile, okuzothinta ukusebenza okuvamile kwemoto.
Umgomo wokusebenza wevalvu yokulawula uwoyela uhilela ukuhlanganiswa komzimba wevalvu kanye nokuhlanganiswa kwe-actuator, okusebenza ndawonye ukuze kufezwe ukulawulwa kokucindezela uwoyela. Kuhlelo lwesikhathi sevalvu eguquguqukayo, ivalvu yokulawula uwoyela ikhetha izifunda ezahlukene zamafutha ukuze ixhumane nesilawuli se-VVT ngokwemiyalelo yokulawula ye-ECU yenjini, ukuze ihlale isikhathi eside noma igcine lezi zimo ezintathu zokusebenza ezahlukene. Le ndlela yokulawula iqinisekisa ukuthi ivalvu iyavula futhi ivale ngesikhathi esifanele, ngaleyo ndlela ithuthukise ukusebenza kwenjini.
Ngaphezu kwalokho, uwoyela, uwoyela wenjini, udlala indima ebalulekile ekunciphiseni ukugcotshwa kwenjini nokuguga, ukupholisa nokupholisa okusizayo , ukuvimbela ukuvuza kokuvala , ukuvimbela ukugqwala nokuvimbela ukugqwala , ukuvimbela ukushaqeka njalo njalo. Kwaziwa ngokuthi "igazi" lemoto. Umsebenzi wevalvu yokulawula uwoyela ukulawula nokuvimbela ingcindezi yohlelo lokugcotshwa kwenjini ukuthi ingabi phezulu kakhulu ukuvikela injini ekulimaleni.
Ivalvu yokulawula uwoyela iphukile
Ukusebenza kokwehluleka kwe-valve yokulawula uwoyela kuhlanganisa kakhulu:
Imoto ingase ime ngokuzumayo ngesikhathi ishayela, okubangelwa ukuthi i-valve yokulawula uwoyela ayikwazi ukulungisa ingcindezi kawoyela ngokujwayelekile, okuholela ekunganele kokugcotshwa kwenjini.
Umfutho kawoyela uphakeme ngendlela engavamile, uma umfutho kawoyela uphakeme kakhulu, kuzoholela engxubeni ejiyile kakhulu, intuthu emnyama evela epayipini lokukhipha umoya, kanye namandla anganele emoto. Ngaphezu kwalokho, umfutho kawoyela ophezulu kakhulu ungabangela nokuthi umfutho kawoyela ube phansi kakhulu noma ungakwazi ngisho nokuma, ngaleyo ndlela kwandiswe ukusetshenziswa kukaphethiloli.
Uwoyela uzosha, okuholela ekusetshenzisweni kukaphethiloli okwandisiwe, ukukhishwa komoya ngokweqile, isivinini esingazinzile sokungenzi lutho, okwandisa izingozi ezifihliwe zemoto nokwandisa umthwalo wezomnotho. Ukushisa uwoyela kuzophinde kuholele ekuqongeleleni okukhulu kwekhabhoni ekamelweni lokushisa injini, ukusheshisa okubuthakathaka, isivinini esihamba kancane, amandla anganele kanye neminye imiphumela emibi.
Umonakalo wevalvu yokulawula uwoyela ubangele ukuzamazama kwenjini, ukwehluleka ukukhanya kuvuliwe. Ikhodi yephutha lokukhipha ingaba yisekethe evulekile yevalvu yokulawula i-VVT, isekethe emfushane eya phansi, noma isekethe emfushane eya ku-electrode enhle. Ngaphansi kwezimo ezivamile, i-waveform ye-voltage yokukhipha ye-terminal kufanele ibe isignali ye-pulse enkulu kakhulu kunesignali enhle, futhi uma i-waveform ingalungile, izobangela ukwehluleka kwenjini.
Ngakho-ke, uma umonakalo wevalvu yokulawula uwoyela utholakala, kufanele welashwe ngokushesha ukuze kugwenywe imiphumela emibi kakhulu.
Iyiphi imiphumela ephuka yivalvu yokulawula uwoyela emotweni?
I-valve yokulawula uwoyela ephukile ingaholela ochungechungeni lwemiphumela emibi, okuhlanganisa ukushiswa uwoyela, ukusetshenziswa kukaphethiloli okwandisiwe, ukukhishwa komoya okweqile, isivinini esingazinzile sokungenzi lutho, kanye namandla anganele.
Ukushiswa kwamafutha: Ukwehluleka kwevalvu yokulawula uwoyela kuzoholela ekushisweni kwamafutha, okuzobangela ukugcotshwa okunganele kwenjini, kukhulise ukuguguleka kwenjini, ngisho nokwehluleka.
Ukusetshenziswa kukaphethiloli okwenyukile: Ukushiswa kukaphethiloli kuzoholela ekwandeni kokusetshenziswa kukaphethiloli enjinini, okuzokwandisa ukusetshenziswa kukaphethiloli emotweni.
Ukukhishwa kwegesi ngokweqile: ukushiswa kwamafutha kuzoholela ekukhishweni kwegesi ngokweqile, okubangela ukungcola emvelweni.
Ukungazinzi kokunyakaza kwenjini: Ukwehluleka kwevalvu yokulawula uwoyela kuzoholela ekungazinzini kokunyakaza kwenjini, imoto izozamazama nezinye izinto lapho ishayela.
Amandla anganele: Ukwehluleka kwevalvu yokulawula uwoyela kuzoholela emandleni enjini anganele, futhi kuzoba nezinkinga ezifana nokusheshisa okubuthakathaka lapho imoto ishayela.
Imoto ingama: Uma ivalvu yokulawula uwoyela iphukile, imoto ingama ngenkathi ishayela.
Ukwanda kwekhabhoni yegumbi lokushiswa kwenjini: Uwoyela ovuthayo uzoholela ekwandeni kwekhabhoni yegumbi lokushiswa kwenjini, ukusheshisa okubuthakathaka, isivinini esihamba kancane.
Ukwanda komthwalo wezomnotho: Ukushisa uwoyela kuzokwandisa umthwalo wezomnotho wemoto, ngoba kudingeka izindleko ezengeziwe zikaphethiloli kanye nokulungisa.
Kuthinta ukusebenza okuvamile kwenjini: ivalvu yokulawula uwoyela iphukile, okuzokwenza ukuthi ingcindezi yohlelo lokugcoba injini ibe phezulu kakhulu, ngaleyo ndlela kuthinte ukusebenza okuvamile kwenjini.
Umsebenzi oyinhloko wevalvu yokulawula uwoyela ukulawula nokuvimbela ingcindezi yohlelo lokugcoba injini ukuthi ingabi phezulu kakhulu. Ngakho-ke, lapho ivalvu yokulawula uwoyela yehluleka, idinga ukwelashwa ngesikhathi ukuze kugwenywe umonakalo enjinini.
