Makina olowetsera mpweya wa crankcase kapena mpweya wa crankcase adapangidwa kuti achepetse kutulutsa kwa zinthu zoyipa kuchokera pa crankcase kupita mumlengalenga. Injini ikayamba kuthamanga, mpweya wotulutsa utsi umatha kutuluka m'zipinda zoyaka moto mu crankcase. Chophimbacho chimakhalanso ndi mafuta, mafuta ndi nthunzi. Pamodzi amatchedwa mpweya wophulika. Kudzikundikira kwa crankcase mpweya kumakhudza katundu ndi kapangidwe ka injini yamafuta, ndikuwononga magawo azitsulo zamagetsi. Makina amakono amagwiritsa ntchito mpweya wabwino. Makina opangira mpweya wa crankcase ochokera kwa opanga osiyanasiyana ndi injini zosiyanasiyana atha kukhala ndi mapangidwe osiyanasiyana. Komabe, zinthu zotsatirazi zikuluzikulu za dongosolo lino zikuwonekera: olekanitsa mafuta, kanyumba ka mpweya ndi mipweya ya mpweya. Chopatula mafuta chimalepheretsa nthunzi za mafuta kulowa mchipinda choyaka moto cha injini, potero amachepetsa kukhazikika kwa mwaye.

Chidule cha makina amafuta a gasi


Kusiyanitsa pakati pa njira yokhotakhota ndi yoyenda yolekanitsa mafuta ndi mpweya. Injini Modern okonzeka ndi olekanitsa mafuta pamodzi. Mu olekanitsa mafuta a labyrinth, mayendedwe a crankcase amachepetsedwa, ndikupangitsa madontho akulu amafuta kukhazikika pamakoma ndikulowa mu crankcase. Olekanitsa mafuta a centrifugal amapereka kupatukana kowonjezera kwamafuta ndi mpweya wama crankcase. Mpweya wopumira wopatulira mafuta umazungulira. Mafuta a mafuta omwe amatsogoleredwa ndi mphamvu ya centrifugal amakhala pamakoma a olekanitsa mafuta ndikulowa mu crankcase. Pofuna kupewa chisokonezo mu crankcase, labyrinth yoyambira yolimba imagwiritsidwa ntchito pambuyo poti olekanitsa mafuta a centrifugal. Uku ndiko kulekanitsa komaliza kwa mafuta ndi mpweya. Dongosolo Crankcase mpweya.

Ntchito ya crankcase gasi


Valavu yampweya wa crankcase imagwiritsidwa ntchito kuwongolera kuthamanga kwa mpweya wa crankcase womwe umalowa munthawi zambiri. Ndi valavu yaying'ono, ndi yotseguka. Ngati pali kutuluka kwakukulu polowera, valavu imatseka. Makina opangira mpweya wa crankcase amatengera kugwiritsa ntchito zingalowe zomwe zimapezeka pakudya kwa injini zambiri. Akasungunuka, mpweya umachotsedwa pa crankcase. Olekanitsa mafuta, magalasi a crankcase amayeretsedwa ndi mafuta. Mpweyawo umawongoleredwa kudzera mu jakisoni kupita kuzambiri, pomwe amaphatikizidwa ndi mpweya ndikuwotcha muzipinda zoyaka. Kwa injini za turbocharged, crankcase ventilation control imaperekedwa. Njira yochotsera nthunzi ya mafuta. Njira yowongolera mpweya yotulutsa evaporative yapangidwa kuti iteteze kutulutsa kwa nthunzi za mafuta mumlengalenga.

Zambiri pa mutuwo:
  Injini ya nkhonya: mitundu, chida ndi momwe amagwirira ntchito

Kodi crankcase system imagwiritsidwa ntchito kuti


Ma nthunzi amapangidwa mafuta akatenthedwa mu thanki yamafuta kapena kukakamizidwa kwamlengalenga kumachepa. Mpweya wa mafuta umadzipezera mu makina injini ikayamba, amawonetsedwa ndikudya kambiri ndikuwotchera mu injini. Njirayi imagwiritsidwa ntchito pamakina onse amakono a injini zamafuta. Njira yobwezeretsa nthunzi ya mafuta imaphatikiza wotsatsa wamakala. Solenoid valavu yoyeretsera ndi kulumikiza mapaipi. Maziko a kapangidwe kake ndi wotsatsa malonda yemwe amatenga nthunzi za mafuta kuchokera mu thanki yamafuta. Adsorber imadzazidwa ndi ma granules opangidwa ndi mpweya, omwe amayamwa mwachindunji ndikusunga mpweya wa mafuta. Adsorber ili ndi maulumikizano atatu akunja: thanki yamafuta. Kudzera mwa iyo, nthunzi zamafuta zimalowa mu adsorber kudzera pakudya kochulukirapo ndi mlengalenga. Kupyolera mu fyuluta ya mpweya kapena chovala chosiyana chodyera.

Chithunzi cha crankcase gasi


Amapanga kupanikizika kosiyanasiyana kofunikira pakutsuka. Chithunzithunzi chatsitsi la mafuta. Kutulutsa kwa adsorber kuchokera mumafuta amafuta omwe amasonkhanitsidwa kumachitika poyeretsa (kusinthika). Valavu yamagetsi ya EVAP imaphatikizidwa mu dongosolo la EVAP kuwongolera njira yobwezeretsanso. Valavu ndiyo yoyendetsa makina oyang'anira injini ndipo ili mu payipi yolumikiza chidebecho ndi zochulukirapo. Chidebecho chimatsukidwa pansi pamachitidwe ena a injini (kuthamanga kwa injini, katundu). Palibe kuyeretsa komwe kumachitika mwachangu kapena ndi injini yozizira. Mukamagwira ntchito yamagetsi yamagetsi, valavu yamagetsi imatseguka.

Mfundo ya crankcase gasi


Mpweya wa mafuta womwe umapezeka mu adsorber umaperekedwa ndi zingalowe m'malo osiyanasiyana. Amatumizidwa kambirimbiri kenako amawotcha muzipinda zoyaka moto za injini. Kuchuluka kwa nthunzi ya mafuta yolowera imayang'aniridwa ndi nthawi yotsegulira valavu. Nthawi yomweyo, injini imakhala ndi mpweya wabwino / mafuta. M'makina opanga ma turbo, palibe zingalowe zomwe zimapangidwa pambiri pokhapokha turbocharger ikuyenda. Chifukwa chake, valavu yowonjezerapo iwiri imaphatikizidwa mu dongosolo la EVAP, lomwe limatsegulidwa ndikutumiza nthunzi zamafuta pomwe chidebecho chimaponyedwa muzambiri kapena mu kompresa polowera pansi papanikizika ya piston.

Zambiri pa mutuwo:
  Kodi ndichifukwa chiyani liwiro loyenda likuwonetsa 200 km / h kapena kupitilira apo?

Mafunso ndi Mayankho:

Chifukwa chiyani mpweya wa crankcase umawoneka? Chifukwa cha kuvala kwa gulu la pistoni. O-mpheteyo akatha, kukanikiza kumafinya ena mwa mpweya mu crankcase. M'mainjini amakono, dongosolo la EGR limatsogolera mpweya woterewu kuti uwotche mu silinda.

Momwe mungayang'anire mpweya wa crankcase molondola? Mawonekedwe a madontho amafuta mu fyuluta ya mpweya, zisindikizo za mafuta ndi pamphambano za chivundikiro cha valve, mikwingwirima ya mafuta ikuwonekera, mikwingwirima ya mafuta pakhosi la filler ndi pa chivundikiro cha valve, utsi wa buluu kuchokera ku utsi.

Chifukwa chiyani mpweya wa crankcase uli wofunikira? Dongosololi limachepetsa kutulutsa kwazinthu zovulaza (kusakaniza kwamafuta, mpweya wotulutsa mpweya ndi mafuta osayaka mumlengalenga) chifukwa chakuwotcha kwawo m'masilinda.
