Kanjani ukuhlola amagesi valve crankcase?

Uma SVKG injini ayisebenzi kahle, kungaba ukuletha umnikazi imoto eziningi izinkinga. I yangaphakathi omlilo injini crankcase kwandisa amandla gas ingcindezi, ngenxa lapho uwoyela uyakhanywa kusukela ngaphansi gasket. Gaza uzobe ngifuna noma yikuphi ukuqhekeka ukuphumela phandle. Ngakho-ke, uwoyela ngeke futhi izogobhoza nezindlala. Ukuze ukuthi amagesi ungakwazi ukuphuma block injini, izimoto zanamuhla, okuthiwa ophoqelelwe ukupholisa hlobo. Lapha, by dilution amagesi kuthiwa ukusivumela indlela eyanele, bese ufaka ekamelweni amandla omlilo, lapho ishiswa. Kuyinto unesibopho le umphini crankcase amagesi. Ngezinye izikhathi kukhona amaphutha ahlukahlukene ezithinta nekusebenta powertrain.

Isikimu zakudala PCV

SVKG wahlela izinto kalula. Izimbotshana motor exhunywe kwi-ezininginingi eyanele. Ngenxa umphumela underpressure ephakama amagesi crankcase kuthiwa ukusivumela le ezininginingi eyanele. Ngemva zingena egumbini amandla omlilo. Into eyodwa kohlelo - valve ka crankcase amagesi. It is iqondiswe ku isiqondiso eyodwa kuphela, ngakho amagesi Ungahambisa kuphela kwelinye direction. Abakwazi ubuyele ku ngalo ingaphakathi imoto. Uhlelo igesi ukupholisa isimiso isinyathelo okusikhumbuza Breather, elitholakala ku PPC design nemoto amabhuloho. Nokho, uma hf ukudluliswa indlela ivuleka, kanjalo ukukhulula amagesi imvelo, khona-ke injini kubangelwa okukhipha osenyameni kungcono kakhulu emandleni iyunithi. Esinye isibonelo - injini ZMZ-24. Kwakuvamise SVKG evulekile. Amagesi angaya emkhathini ngepayipi, eyayiseSwitzerland kwesembozo somphongolo pusher. Kusukela ngo-1977, ukwakhiwa kwaleli kwesokunxele futhi waqala ukusebenzisa ophoqelelwe ukupholisa uhlelo. It yavalwa. Ngokusebenzisa hose ekhethekile wasuka isembozo valve injini, igesi ngaphansi carburetor. Ngenxa ukwethulwa izixazululo ukwehlisa kwekhabhoni imithi enobungozi endaweni ezungezile. It wakwazi sina ukunciphisa izinga ingcindezi ngaphakathi crankcase. Kungenzeka ukuxazulula izinkinga ngezimpawu extruded futhi gaskets. Injini engu esifushane umoya, kukhuphuke powertrains ukoma. Classical SVKG isikimu ubalula izinhlobo ezimbili zemali gas osenyameni izindlela - co-wamanje kanye ukususwa ngenkani. Isibonelo - uhlelo lokusebenza nganoma ZMZ-402. Lokhu injini ngokuqondile valve ikhava ezininginingi ngokusebenzisa igesi engenhla kukhishelwa endlini carburetor. Kukhona ipayipi aphansi. It yakhelwe sokukhipha KG ngokudlula carburetor ngqo ipheshana eyanele.

Valve ka crankcase umoya ovela umlando

Sesihlole nomqondo umsebenzi ophoqelelwe ukupholisa uhlelo. Njengoba kuphawulwe ngenhla, isakhiwo oyinhloko valve akhethekile, unesibopho kabusha amagesi. Le divayisi elula esiza ukunciphisa izinga izinto eziyingozi. Ngokokuqala ngqá mayelana isidingo sokuthatha lezi amadivayisi baqala ukukhuluma 70s. Kwakuphakathi nalesi sikhathi eseqala ukucabangisisa ngemvelo futhi mayelana nemiphumela elimazayo ukuthi babe amagesi qeda. Through isicelo of crankcase igesi recirculation umphini afterburned kule amasilinda. Njengoba ezingcolisa ehlukahlukene combusted, uwoyela nezinye izinto. Valve ka crankcase amagesi engaphezu kwengu-15 kakhulu sashintsha kaningi. Onjiniyela washintsha isimo sawo futhi isimiso wokusebenza. Ngonyaka lama-77 sisungule futhi isicelo isakhiwo mechanical ne counterpressure omuhle. iminyaka engu-2 kamuva, ngonyaka 79th, kuthiwa lathathelwa indawo valve mechanical, kodwa nge ingcindezi ezimbi. Esikhathini 88th saqala ukuqaliswa valve leyehlukene kanye solenoids ezintathu. C 90s ziye ngenkuthalo esetshenziswa amadivaysi ezehlukene nge solenoids ezimbili. Le ndlela yokwenza zingalawula ukugeleza igesi ngenxa esisodwa esikhulu futhi omunye imbobo encane. Lokhu kuqinisekisa ezintathu ukugeleza ezahlukene. Lo mklamo wazibonakalisa enokwethenjelwa kakhulu futhi yasetshenziswa ngempumelelo ngisho namuhla izimoto zanamuhla (isib, "Kia Sorento" umphini we crankcase amagesi).

Umgomo we operation

Lapho ingxube amafutha kanye umoya combusted egumbini ngamazinga ashisa kakhulu kakhulu, nitrogen ikhishwe. Ndawonye umoya-mpilo, kungaba akha izinto eziyingozi lapho umonakala ithonya imvelo. Lokhu nitrogen oxides. Ngaphansi kwezimo ezithile, ekamelweni omlilo lokushisa injini omlilo mkhulu ejwayelekile, ngenxa okuyinto lemali nitrogen oxides luyanda kakhulu. Iningi imizamo ukuze ifohle iye phansi block injini. Ukuze ukuthi ingcindezi engakhuli ezingeni esibucayi, kubalulekile ukuba emgodini. Kuze kube yileso sikhathi, kuze izinjini kwase akukakasetshenziswa uhlelo kabusha, amagesi, njengoba sekuphawuliwe kakade, uvela Breather crankcase. Ake sibheke indlela valve ka crankcase amagesi. Umgomo we operation silula. Kusekelwe umphumela cleaner ku ezininginingi eyanele. Ngale ndlela, ngo-cleaner transducer, uhamba valve shaft, kanjalo kokuvula idivayisi. Ngo izimoto zanamuhla ezimbili zama-amadivayisi asetshenziswa. Lokhu izinhlelo mechanical electronic. Futhi, electronic namanje lahlukaniswa izinhlobo - leyehlukene kanye komugqa. Leli bhokisi we beso cleaner block isilinda has port cleaner. Yena ihlanganyela carburetor noma mpintsha ukuba ekhoneni. Kuye onjani ukucindezeleka kwenzeka ezininginingi eyanele, i-beso yokucina ku inqubo kokuvula ukucindezela ku shift isigwedlo stepless. Lokhu yakha isignali ethize uvula valve ulwelwesi electronic. Lapho izinga isignali kwandisa, diaphragm uqala ukunyakaza phezulu ngokumelene amandla entwasahlobo lokuhambisa plunger. Ngenxa yalokhu, ngo-kuvulwa valve etholakala. Amagesi kungenzeka ungene ezininginingi eyanele. Uma injini is idling noma lapho izinga cleaner echibini lincane, plunger uvala. Amagesi ezininginingi ngeke akwenze.

Valve kudivayisi VCG

Ngo yesimanje omlilo yangaphakathi izinjini ngokuvamile zisebenzisa ulwelwesi uhlobo valve PCV. idivayisi wakhe ezinzima elula. I element siqukethe umzimba nge nokufakwa ezimbili. Omunye ungumbonisi lokondla umphakathi yesibili - ngokuchitha amagesi. Kukhona cap, diaphragm noma ulwelwesi kanye entwasahlobo ukubuya.

Izici okusebenzela kuyo PCV valve

Lo mklamo usebenza kanje. Lapho injini akasebenzisi, valve ngaphansi entwasahlobo osikweni crankcase gases "Audi A4 'uzovimbelwa ngenxa ulwelwesi. Lapho injini idling, cleaner ngenxa ulwelwesi uqala kancane kancane unqobe entwasahlobo. Ingxenye igesi kusukela injini engena i ezininginingi eyanele. Ngesivinini ulwelwesi ivuliwe ngokugcwele. Gaza matasa ngokugcwele ngalendoda.

Izinkinga ezivamile

Zonke izinkinga ezingase zenzeke nale divayisi zingahlukaniswa zibe izinhlobo ezimbili - ukuwohloka ezahlukene valve futhi odla. On kubo kuzoxoxwa ngezansi. Isikhathi esining impela sezizathu esenza ehluleka crankcase gas valve ( "Polo 1.4" - iyathinteka), angawodwa bafake engokwemvelo izingxenye nezingxenye eqenjini isilinda-piston. Uma amandla omlilo has a ababuthakathaka kokucindezelwa emakamelweni, kanye iringi uwoyela phezu piston kunesithembiso igrisi kanti ukucindezeleka igesi inyuka crankcase. Uhlelo ukupholisa akakwazi ukubhekana lesi simanga. Amafutha, umule kanye neminye imikhiqizo amandla omlilo ngokoqobo clog amapayipi kanye hoses, kanjalo kokuyekethisa ubuqotho ulwelwesi valve. Uma Imibhobho esemzimbeni baba avimbekile, futhi odla kohlelo ukupholisa, amagesi izozama ukuba basinde ngokuwela iyiphi indawo kungenzeka futhi uxhumano. Ngakho-ke, ukugeleza ngokusebenzisa izimpawu kanye gaskets isibambo uwoyela.

Kuxhunyiwe

Valve ka crankcase gases "Passat B3", njengawo wonke amanye zalolu hlobo, uthambekela odla. Lokhu kungaholela wenza umcimbi mshini. Phenomenon ngempela nomthelela ekusebenzeni injini. Uma valve is washaya i isikhundla evulekile, ke ngizamvusa ikhule ngesivinini kokungenzi lutho ngaphakathi abalulekile petrol. Engine idling iba engazinzile. Uma valve ka crankcase amagesi ( "Skoda Octavia" ngokuvamile yilesi) ubhajwe kule sikhundla avaliwe, ngaleso sikhathi kuyoba khona ukukhuphuka igesi ukugandeleleka crankcase. Ekubhekile konke ukuvuza uwoyela kwenzeke lwezimpawu kanye gaskets. Ngokuvamile lapho zinamaphutha kakhulu iphazamiseke uhlelo uwoyela.

Kanjani ukuhlola kudivayisi? indlela №1

Uma imoto waphawula izimpawu ezifanayo, kubalulekile ukuhlola valve PCV. Kunezindlela ezimbili ukuhlola. Uma ususa valve crankcase "Passat B3", ingashiswa yakhe okufanele kwenzeke kuphela kwelinye direction. Umoya ukubuya sihamba cishe akufanele. It bavunyelwe kuphela inani elincane ke, okungathatha indawo. Uma konke kuhamba kahle, khona-ke uhlelo luyasebenza.

indlela №2

Eyesibili inketho - kuyinto ukuhlola ku injini egijima. Ngenxa yale njongo valve linqamuka amapayipi we ezininginingi eyanele. Uma into engaphelele, khona-ke ngeke angakhishwa. It okungase kuthintwe, uma ubeka umunwe wakho inyunyana. Uyozizwa njengomhubi umunwe inamathela imbobo. Uma valve kuyinto crankcase okuyiphutha "Volkswagen Touareg" ke zichithe okwamanje ngeke.

Izici crankcase ukupholisa izinhlelo izimoto iqembu VAG

Blow by VAG izimoto unedivaysi eyinkimbinkimbi ehambisana. Uhlelo lusebenzisa omningi imininingwane kusuka epulasitikini futhi izingono zenjoloba. Phakathi kokusebenza wemoto coked hoses. Khona-ke ngeke ukusula zonke izinto. Ngaphambili kule ndaba, inkinga isixazululekile nje. Uhlelo ukupholisa ecaleni ukuze amboze valve uhlelo tube efakwe noma hose kanye amagesi adedelwa imvelo. Kodwa le ndlela has a lot of amaphutha. Gaza sina bangcolise indawo ezungezile, umshayeli nabagibeli emotweni, futhi, benza ukuphefumula. On izimoto zanamuhla ngakho akekho ayisekho abathintekayo, futhi uma ivimbekile ukuba VW umphini we crankcase amagesi, umnikazi kudingeka ukuhlanza lonke uhlelo. Amagesi crankcase ku izinjini amaqembu VAG zihlobene yini kusukela isembozo valve futhi block injini, okuyinto aboshelwe isihlukanisi wazalela (elise ohlangothini kwesokudla iyunithi). Idivayisi akuvumeli uwoyela i Imibhobho esemzimbeni e SVKG. Ukuze uthole ncamashi amagesi futhi akukho okunye. Ukuze isihlukanisi amafutha Ulungise tube plastic kanye phakathi tube futhi lokhu tube efakwe tee, futhi lapho valve itholakala. Kungaba usebenza izindlela ezintathu. Ngezinye ngomzuzu angomahlalela okusezingeni eliphezulu kuba avaliwe, futhi ivula lapho injini isebenza ngesivinini ophansi.

isiphetho

Njengoba kuboniswe, nekusebenta injini luncike isici esincane. Lapho ukusebenza asebenzayo wemoto kuyadingeka ukuqapha isimo valve futhi lonke uhlelo ukupholisa, futhi ukwazi ukubhekana kahle yokuhlanza kunesidingo.
