Yini i-valve uvemvane?

Uyini umphini wevemvane?
 

Enjinini yephethiloli yendabuko, i-valve mpintsha iyinto ebaluleke kakhulu ohlelweni lokungenisa umoya. Ngamanye amagama, ilawula inani lokuhamba komoya okungena egumbini lokushisa kwenjini yemoto.

Njengokwakhiwa, ivalvevemvane ilula. Siqukethe ikakhulukazi umzimba oyindilinga lapho kuneveluvemvane ("uvemvane") elizungeza i-eksisi nenzwa.

Iphi le valve futhi isebenza kanjani?
 

Njengoba umsebenzi oyinhloko we-valve ye-throttle ukulawula nokulawula inani lomoya ongena ekamelweni elivuthayo, kungaba khona indawo eyodwa kuphela - phakathi kwesihlungi somoya kanye nenqwaba yokungenisa.

Lapho i-pedator ye-accelerator icindezelekile, ipuleti ku-valve livuleka futhi livumela umoya ukungena egumbini lomlilo. Lapho isigwedlo sikhishwa, ipuleti liyavalwa futhi liminyanise umoya ogeleza ekamelweni lomlilo. Inani lomoya ohlanzekile i-valve elingena egumbini lomlilo lilawula ijubane lenjini, okusho ukuthi lilawula nejubane lemoto.

Izinhlobo nokusebenza kwe-valve mpintsha
 

Uhlobo lwe-valve lunqunywa ukwakheka kwalo, i-actuator nemodi yokusebenza. Ngokuya ngalezi zinto, singasho ukuthi kunezinhlobo ezimbili zamavalvu ovemvane: ezisebenza ngomshini nezikagesi.

Amaphayiphu wempintsha ane-mechanical drive
 

Izimoto ezindala zivame ukufakelwa ama-butterfly asebenza ngomshini. Isici esivelayo sale modi yokusebenza ukuthi i-accelerator pedal ixhunywe ngqo ku-valve ngentambo ekhethekile.

Imodi ye-valve eqhutshwa ngamandla kagesi imi kanje:

Lapho i-pedacator ye-accelerator icindezelekile, uhlelo lwe-levers nezintambo kuyasebenza okuvula i-valve. Ngenxa yalokho, umoya uqala ukungena ohlelweni bese wenza inhlanganisela yomoya kaphethiloli.

Uma kunikezwa umoya omningi, kunikezwa uphethiloli omningi futhi ijubane lemoto liyakhuphuka. Lapho ukukhishwa kwe-accelerator sekukhishwa, i-valve mpintsha iyavala ukuze kungene umoya ohlanzekile, okwenza injini yehlise ijubane emotweni.

Amaphayiphu walolu hlobo awagcini nje ngesimanje kuphela kunawomshini, kepha futhi anezimiso ezihlukile zokusebenza. Ngokungafani nama-valve womshini, ama-valve kagesi awadingi ukuxhumeka kwemishini esenzweni se-accelerator. Esikhundleni salokho, basebenzisa ukulawulwa kwe-elekthronikhi okuvumela ukulawula kokugeleza komoya okuzenzakalelayo ngokuphelele.

Izinkinga ezivame kakhulu ngamaveluvemvane
 

Njenganoma iyiphi ingxenye yemoto noma isistimu, i-valve mpintsha, noma ngabe iyimishini noma i-elekthronikhi, ingaguga. Ngenhlanhla, lokhu akuvamile ngoba lezi zingxenye ziqine kakhulu futhi zihlala isikhathi eside, futhi kungenzeka ukuthi akudingeki ukuthi ushintshe i-valve ngenkathi ushayela.

Kodwa-ke, kuyasiza ukwazi izimpawu eziyinhloko ezibonisa ukuthi i-throttle ayisebenzi kahle.

Ukungasebenzi kahle kwenjini
Amadiphozithi akheka ngaphakathi komzimba we-throttle (valvu) ngokuhamba kwesikhathi, okunganciphisa noma kuphazamise ukugeleza komoya omusha endaweni evuthayo. Uma lokhu kwenzeka, uphethiloli nomoya akukwazi ukuhlangana kahle, okubangela ukungalingani kuphethiloli - ingxube yomoya kanye nenjini ngeke kusebenze kahle.

Ama-Carbon deposits enza ngendlela efanayo nokungcola okunqwabelene. Zinqwabelana ezindongeni mpintsha futhi ziphazamise i-atomization yenhlanganisela yomoya-uphethiloli.

Inkinga yenzwa
Uma inzwa etholakala emzimbeni wempintsha ilimele, ithumela imininingwane engalungile kukhompyutha yemoto, okuholela ekuxubeni okungafanele komoya nophethiloli egumbini lomlilo.

I-rpm ephansi futhi ayisebenzi
Lapho i-throttle ivinjiwe noma igugile, esinye sezibonakaliso ezivame kakhulu zokungasebenzi kahle ukungakwazi ukusheshisa imoto. Akunandaba ukuthi uzama kanzima kangakanani, ijubane lemoto lizoba phakathi kuka-500 no-1000, futhi injini izodlidlizela kakhulu futhi ngamandla kakhulu kunakuqala.

Ukusetshenziswa okuphezulu kukaphethiloli
Uma ukusetshenziswa kukaphethiloli kwehla kungazelelwe futhi imoto ingasheshisi kahle, lokhu kungesinye isibonakaliso sokuthi kunenkinga ye-throttle.

Ngabe i-valve mpintsha ingalungiswa?
 

Eqinisweni, uma i-valve iphuka noma iphela, ayinakulungiswa futhi kufanele ithathelwe indawo entsha. Ngenhlanhla, iningi lezinkinga zalo lingaxazululwa kuphela ngokuhlanzwa. Abakhiqizi batusa ukuhlanzwa kwe-valve njalo ngamakhilomitha angama-30-40, noma ngabe ungakaqapheli noma yiziphi izimpawu esizibalile.

Ukuhlanza akunzima kangako, futhi uma unesikhathi, isifiso, namathuluzi ambalwa ayisisekelo, ungazenzela ngokwakho.

Ungayihlanza kanjani i-valve uvemvane?
 

Konke okudingayo ukuhlanza i-valve kungumuthi okhethekile wokuhlanza, ithawula kanye ne-screwdriver yekhanda eyisicaba. Uma besesandleni sakho, landela lezi zinyathelo:

Misa injini bese uthola ipayipi eliningi lokudla. Landela uze ufinyelele kubakaki eliyixhuma ku-mpintsha
Sebenzisa i-screwdriver ukukhulula uqinisa bese ususa ipayipi.
Uma kukhona amanye amapayipi, asuse
Ngaphambi kokufafaza i-valve ngensipho, thola ukuthi inzwa ikuphi futhi uqaphele ukuthi ungayifafazi.
Futha ngomuthi wokuhlanza bese ulinda imizuzu embalwa
Xhuma wonke amapayipi emzimbeni wempintsha.
Thatha idrayivu yokuhlola. Qala injini bese uzungeza indawo. Uma i-valve ihlanzwa kahle, injini kufanele ihambe kahle futhi intuthu ephuma ku-muffler kufanele ibe nombala ojwayelekile.
Ukuhlanza i-valve mpintsha

Uma kungenzeki okuguqukayo, kuzodingeka ukuthi ufake enye i-valve esikhundleni salo.

Ungayishintsha kanjani i-valve yovemvane?
 

Amathuluzi ozowadinga uma unquma ukufaka okunye kokuminyene wena: izisululifili, izigaxa, isethi yamawrensi nophintshisi.

Vele, kufanele uthenge i-valve entsha yovemvane ngaphambi kokuqala umsebenzi wokushintsha. Ungathola ukuthi kuyini ngokubheka ibhukwana lemoto yakho noma ngokubuza isitolo sezingxenye zezimoto lapho ungathanda ukuyithenga khona le ngxenye.

Into yokugcina oyidingayo izingubo zokuzivikela. Imvamisa, izingubo zomsebenzi ezintofontofo, izibuko kanye namagilavu ​​zanele ukuqinisekisa ukuphepha kwakho.

Izinyathelo zokufaka esikhundleni se-valve mpintsha
 

• Misa injini, thola i-valve mpintsha, bese unqamula zonke izintambo namapayipi axhunywe kuyo.
• Qiniseka ukuthi ucisha ukunzwa kwamandla kanye nokushisa komoya
• Yenza kungasebenzi inzwa yesimo sempintsha
• Susa wonke amabhawodi abamba umzimba wokugoqa
• Ngokuvamile kunezine zazo futhi zinamathisela umzimba wempintsha kokuphindaphindwayo kokudla.
• Uma uqaqa amabhawodi, uzobona futhi uphawu. Qaphela lokhu ngoba uzokusebenzisa uma ufaka i-valve entsha
• Susa isivalo esidala sokumpintsha bese uhlanza indawo kahle.
• Faka umzimba omusha we-valve. Qiniseka ukuthi uphawu lukhona, faka i-valve, uyivikele ngokuqinile kokuphindaphindwayo kokudla bese uqinisa amabhawodi.
• Xhuma zonke izinto ngokulandelana okuphindayo kokulayisha
• Esikhundleni valve mpintsha

Okubalulekile. Ngaphambi kokuzama ukufaka i-valve esikhundleni njengoba sikukhombisile, qiniseka ukuthi le miyalo ilungile kwimodeli yemoto yakho. Uma ukuthola kunzima ukufaka i-valve mpintsha ngokwakho, kungcono uxhumane nensizakalo ekhethekile, lapho izongena khona ngokushesha nangobuchwepheshe ngokuphelele.
