Likuphi VVTI valve futhi kanjani ukuhlola?

VVTI - bakhula "Toyota" simiso variable valve isikhathi. Uma sihumusha le isifinyezo kusuka olimini lwesiNgisi livela kwelesiLatini, lesi simiso unesibopho esigabeni bokusungula offset. Manje izinjini yesimanje Japanese abafake izindlela isizukulwane sesibili. A VVTI kuqala efakwe izimoto kusukela ngo-1996. Uhlelo kuyinto emikhonweni kanye VVTI valve akhethekile. Kugcine ukhonza njengelungu inzwa.

Uhlelo kudivayisi umphini VVTI imoto "Toyota"

I element siqukethe umzimba. Engxenyeni yangaphandle kukhona Solenoid control. Yena unesibopho ukuhamba valve. Futhi, amalungiselelo kukhona uphawu izindandatho Isixhumi ngoba inzwa.

Isimiso jikelele ukusebenza ohlelweni

Inkosi iyunithi kule isikhathi ohlelweni offset - bamba VVTI. Ngokuzenzakalelayo, onjiniyela injini baklame isigaba umphini ukuvulwa ukuze bathole traction ezinhle ngesikhathi revs ongaphakeme injini. Njengoba ijubane ikhula, uwoyela ingcindezi, ngenxa ukunikela VVTI valve. "Toyota Camry" futhi 2.4-litre yayo injini ugijima on isimiso esifanayo.

Uma lokhu valve ivulekile, le camshaft sizophenduka at endaweni ethile mayelana isondo lokugijimisa indiphi elenzelwe into esindayo. I Cams ku kushaft kuthiwa ilolongwe ngokukhethekile itheku valve eyovulwa kancane ngaphambili inqubo turning isici. Ngakho, ngemva kwesikhathi ivaliwe. Lokhu kumele kube nendlela engcono kakhulu yokubuyela nomthelela emandleni ne torque yenjini at revs okusezingeni eliphezulu.

Ukusebenza okuningiliziwe

Main ukulawula indlela kohlelo (futhi lokhu bamba) efakwe kwi injini camshaft isondo lokugijimisa indiphi elenzelwe into esindayo kushaft. Ezezindlu ixhunywe inkanyezi noma isondo lokugijimisa indiphi elenzelwe into esindayo toothed. Rotor ixhunyiwe ngqo camshaft. Amafutha kusukela uhlelo Lubrication ihlinzekwa komunye noma bobabili izinhlangothi Rotor ngamunye Lobe phezu elihlangana, abangela camshaft ukujikisa. Lapho injini akasebenzisi, uhlelo usetha ngokuzenzakalela esiphezulu ukubambezeleka engeli. Bona sihambisana ukuvulwa ngasekupheleni kanye nokuvala valve eyanele. Lapho imoto iqalisiwe, umthamo kawoyela engaqinile ngokwanele ukuba akwazi ukuvula VVTI valve. Ukuze kungabikho muntu ophathwa uthuthumele ohlelweni, Rotor ixhunywe bamba izindlu pin okuyinto lapho igrisi ingcindezi luyanda uzobe wakhama by amafutha.

ukusebenza System ilawulwa valve akhethekile. On isiginali kusuka ECU, uzibuthe kagesi usebenzisa plunger iqala ukuhambisa spool, kanjalo ngokuvumela amafutha omunye isiqondiso. Lapho imoto is sinqamukile, spool uhamba nge entwasahlobo ukuze usethe esiphezulu ukubambezeleka engela. Ukushintshanisa camshaft ngumuntu engela ezithile, uwoyela ngaphansi kwengcindezi ophakeme valve ihlinzekwa komunye uhlangothi iyizingxenye Rotor. Ngesikhathi esifanayo kwasivulela sokukhipha umgodi ekhethekile. Itholakala ngakolunye uhlangothi isigcebe sembali. Uma ikhompyutha bazokubona ukuthi camshaft iphendukiswa-engeli oyifunayo, iziteshi isondo lokugijimisa indiphi elenzelwe into esindayo kuyendlulela futhi uyonikwa okwengeziwe zigcinwe kulesi sikhundla.

izimpawu ejwayelekile zezinkinga VVTI uhlelo

Ngakho, uhlelo udinga ukushintsha isigaba ukusebenza isikhathi. Uma kukhona noma iyiphi inkinga-ke imoto ngeke bakwazi ukusebenza ngokujwayelekile esicini esisodwa noma ngaphezulu yokusebenza izindlela. Kukhona izimpawu eziningana ukuthi uzokutshela iphutha.

Ngakho, imoto akaphinde asibalele kokungenzi lutho ezingeni elifanayo. Lokhu kusikisela ukuthi VVTI valve ayisebenzi njengoba kufanele. Futhi ngezinkinga ezihlukahlukene ohlelweni khona oyothi "okusithiyayo" yenjini. Ngokuvamile, lapho izinkinga isigaba ushintsho indlela akunakwenzeka ukusebenzisa motor ngesivinini aphansi. Enye yezinkinga nge valve angakhuluma iphutha P1349. Uma kushiswa amandla Iyunithi yesivinini kokungenzi lutho okusezingeni eliphezulu, imoto hhayi ukuhamba.

izimbangela ukwehluleka valve

Ziyini izimbangela eziyinhloko zalokhu of valve Iphutha alikho ngempela lukhulu. ezimbili ezenzeka avame kungathiwa. Ngakho, VVTI valve ongahlabeki ngenxa yokuthi kukhona amakhefu e kwekhoyili. Kulokhu, element ngeke bakwazi ukuphendula kahle ukuze voltage yokudlulisela. Fault ukuhlola kwenziwa kalula ngokuhlola ikhoyili wokulinganisa ukumelana ikhoyili inzwa.

Eyesibili yokuthi VVTI umphini (Toyota) ayisebenzi kahle noma bengasebenzi nhlobo - it is wenza umcimbi in isitokwe. Imbangela Jamming ingaba ukungcola evamile nje iye efunde ngokuhamba kwesikhathi esiteshini. Kungenzeka futhi, zikhubazekile uphawu gum ngaphakathi valve. Kulokhu, ukubuyisela indlela silula - nje ukuhlanza udoti ngaphandle. Lokhu kungenziwa ngokusebenzisa sifakwe emanzini noma isici steeping e uketshezi ekhethekile.

Indlela ukuhlanza valve?

Izinkinga eziningi ingelapheka ngosizo inzwa yokuhlanza. Okokuqala udinga ukuthola VVTI valve. Kuphi lokhu kuba khona isici kungabonakala isithombe ngezansi. Yena azungeza esithombeni.

Ukuze ahlukanisa inzwa sisuswa ikhava plastic amandla iyunithi. Khona-ke ukhipha ikhava sensimbi, okuyinto elungisa generator. valve oyifunayo zizobonakala ngaphansi ikhava. Njengoba kubalulekile unqamule isokhethi kagesi uyasikrufulula umshudo. Iphutha lapha kunzima kakhulu ukuvimbela - omunye umshudo lapha kuphela. Khona-ke VVTI 1NZ umphini kungaba zisuswe. Kodwa musa donsa isixhumi le njongo. He is Friend kakhulu inzwa. Futhi ukukhwezwa kwalo indandatho iraba uphawu.

Nokuhlanzwa engenziwa nge uketshezi for yokuhlanza carburetors. Ukuhlanza ngokuphelele uhlelo, futhi ususe isihlungi. Le nto ngaphansi valve - it is a stub lapho kukhona umgodi ukuze iheksagoni. Lemifanekiso futhi kufanele zihlanzwe lolu ketshezi. Phela imisebenzi kungaba kuphela babuthane oda reverse, bese ufake ibhande generator, hhayi uphumule Kulokhu e valve uqobo.

Indlela hlola valve VVTI?

Hlola ukuthi valve silula. Ukuze wenze lokhu, le inzwa yanikezwa voltage 12 V. oxhumana Kumele kukhunjulwe ukuthi ukugcina isici abakwazi ukuphila isikhathi eside, ngoba asikwazi ukusebenza ngaphansi kwalezizimo isikhathi eside kangaka. Ngesikhathi ashukumisayo induku kubuyiswe ngaphakathi. Umbonisi kuzovula uma kuziwa emuva.

Uma induku idluliswa kalula, valve kuyinto ukusebenza ngokugcwele. Idinga kuphela iphume, amafutha kungenziwa eziqhutshwa. Uma kungaphumeleli njengoba kufanele, khona-ke ukusiza ukulungisa noma esikhundleni the VVTI valve.

Independent valve ukulungisa

Okokuqala ahlukanisa zokulawula ibha generator. Khona-ke ukususa iziqobosho bonnet yokuvala. Lokhu kuzovula ukufinyelela generator umshudo Axial. Okulandelayo baphotha ibhawudo ebamba valve ngokwayo, bese uyalikhipha. Ngemva lemifanekiso okungukuthi ekhishiwe. Uma kungxenye yokugcina kanye valve ingcolile ke lezi izingxenye bahlanza. Ukulungisa iwukuba kanye Lubrication. Ungase futhi esikhundleni indandatho uphawu. ukulungisa Ukungaphathwa akunakwenzeka. Uma into kungasebenzi, kuba lula futhi eshibhile ukufaka esikhundleni salo esisha.

Self VVTI valve esikhundleni

Okuvamise ekuhlanzeni Lubrication alinikezi elamukelekile, futhi umbuzo esikhundleni ephelele izingxenye. Ngaphezu kwalokho, abaningi abanikazi imoto ngemva esikhundleni ukuzisholo kwazo ukuthi umshini waqala ukusebenza ngcono futhi petrol kwehle.

Ukuze uqale, ukususa zokulawula ibha generator. Khona-ke ukususa iziqobosho bonnet Ilokhi futhi afinyelele generator umshudo. umshudo Otkraivayut ukuthi udinga valve yomngcwabo. elementi Old kungenziwa kukhishwe kulahlwe, futhi elidala ubeke endaweni entsha. Khona-ke ukusonta umshudo kanye imoto kungenziwa eziqhutshwa.

isiphetho

izimoto anamuhla kokubili okuhle nokubi. Ziyakwazi okubi ukuthi akuwona wonke ukusebenza ezihambisana ukulungiselwa kanye nokugcinwa, engenziwa ngokuzimela. Kodwa nansi indawo valve ngezandla zakho ongenza, futhi lokhu a plus elikhulu umenzi Japanese.
