Chii chinonzi mota crankcase system?

Crankcase gasi system

Iyo crankcase kufefetedza system kana crankcase gasi system yakagadzirirwa kudzikisira kuburitsa kwezvinhu zvinokuvadza kubva kune crankcase kuenda mudenga. Kana injini ichimhanya, gasi rekudzimisa rinogona kupukunyuka kubva kumakamuri emoto mune crankcase. Iyo crankcase zvakare ine mafuta, peturu uye chiutsi. Pamwe chete ivo vanonzi kufema-nemweya. Iko kuunganidzwa kwe crankcase magasi kunokanganisa chivakwa uye kuumbwa kweinjini yemafuta, uye kunoparadza simbi injini zvikamu. Injini dzemazuva ano dzinoshandisa yakamanikidzwa crankcase kufefetedza system. Iyo crankcase yekufefetera system kubva kune akasiyana vagadziri uye akasiyana mainjini anogona kunge aine akasiyana magadzirirwo. Nekudaro, zvinotevera zvinotevera zvimiro zvechimiro zveiyi sisitimu zvinomira pachena: chiparadzanisi chemafuta, crankcase kufefetedza uye mweya yemhepo. Muparadzanisi wemafuta unodzivirira mhute yemafuta kuti isapinda mukamuri yemoto yeinjini, nokudaro ichideredza kuumbwa kwesipo.

Ongororo yegasi kadhi system

Siyanisa pakati pema labyrinth nema cyclical nzira dzekuparadzanisa oiri nemweya. Injini dzemazuva ano dzakashongedzerwa nesanganiswa yekuparadzanisa mafuta. Mune labyrinth mafuta separator, kufamba kwe crankcase kunodzikira, zvichikonzera madonhwe makuru emafuta kugara pamadziro uye kupinda mujini crankcase. A centrifugal oiri separator inopa kumwe kuparadzaniswa kwemafuta kubva ku crankcase magasi. Kufuridza nemweya unopfuura nepakati pekuparadzanisa mafuta kunotenderera. Mafuta emafuta ari pasi pekuita kwesimba re centrifugal anogara pamadziro eanopatsanura mafuta opinda mugirafu. Kudzivirira kusagadzikana mune crankcase, labyrinth-mhando inotanga kudzikamisa inoshandiswa mushure mekuparadzanisa oiri centrifugal. Uku ndiko kupatsanurwa kwekupedzisira kwemafuta nemweya. Crankcase kufefetedza system.

Crankcase gasi system mashandiro

Iyo crankcase yemhepo vharuvhu inoshandiswa kugadzirisa kumanikidza kweye crankcase magasi anopinda mune yakawanda yekudyira. Iine vharuvhu diki, yakavhurika. Kana paine kuyerera kwakakosha mune iyo inopinda, vharuvhu inovhara. Iyo crankcase yekufefetedza system inoenderana nekushandiswa kwevhavha inoitika mune yakawanda yekudyara yeinjini. Kana yakadzvanywa, magasi anobviswa mu crankcase. Muchiparadzanisi chemafuta, magasi crankcase anonatswa kubva kumafuta. Iwo magasi anobva aendeswa kuburikidza nemajekiseni kuenda kune yakawanda yekudyira, kwaanosanganiswa nemhepo uye kupiswa mumakamuri emoto. Kune turbocharged injini dzinopihwa crankcase yekufefetera yekudzora kudzora. Peturu pombi yekudzosa system. Iyo evaporative emission kudzora system yakagadzirirwa kudzivirira kuburitswa kwemafuta epeturu mumhepo.

Iripi crankcase system rinoshandiswa

Mhepo inoputika inogadzirwa kana peturu ichidziya mutangi remafuta kana kana kumanikidzwa kwemhepo kuchinge kwadzikira. Mafuta emafuta epeturu anoungana muhurongwa kana injini yatanga, inoratidzwa mune yakawanda yekudya uye kupisa mukati meinjini. Iyo sisitimu inoshandiswa pane ese mamodheru emhando dzemafuta epeturu. Iyo peturu mhute yekudzoreredza system inosanganisa iyo yemarasha adsorber. Solenoid vharafu yekuchenesa nekubatanidza mapaipi. Hwaro hwesisitimu dhizaini ndeye adsorber iyo inounganidza huni hwepeturu kubva mutangi remafuta. Iyo adsorber yakazadzwa neyakaomeswa kabhoni granules, ayo anonanga uye anochengeta peturu mhute. Iyo adsorber ine matatu ekunze kubatana: iyo peturu tangi. Kubudikidza naro, mafuta emafuta anopinda mu adsorber kuburikidza nekudyiwa kwakawanda pamwe nemhepo. Kubudikidza nefirita yemhepo kana vharuvhu yekudyira yakasarudzika.

Crankcase gasi system dhayagiramu

Inogadzira kusiyanisa kumanikidza kunodiwa pakuchenesa. Peturu pombi yekudzoreredza dhayagiramu. Kuburitswa kweye adsorber kubva kune yakaunganidzwa peturu mhute inoitwa nekuchenesa (kumutsidzira). Iyo EVAP solenoid vharuvhu inosanganisirwa muEvAP system kudzora maitiro ekumutsiridza. Iyo vharuvhu ndiyo inosimudzira yeinjini manejimendi system uye iri mune pombi inobatanidza mudziyo kune yakawanda yekudyira. Mudziyo unonatswa pasi peimwe injini mashandiro ezvinhu (injini kumhanya, mutoro). Hapana kuchenesa kunoitwa nekumhanyisa zvisina basa kana neinjini inotonhora. Paunenge uchishanda neyemagetsi control unit, iyo solenoid vharafu inovhura.

Crankcase gasi musimboti

Mafuta emafuta epeturu ari mu adsorber anopihwa nevhavha kune yakawanda yekudyira. Dzinotumirwa kune dzakawanda uye dzinopiswa mumakamuri emagetsi einjini. Huwandu hwepeturu mhute inopinda inodzorwa nevhavha yekuvhura nguva. Panguva imwecheteyo, injini inochengetedza yakaringana mweya / mafuta chiyero. Muma turbo engines, hapana vacuum inogadzirwa mukudyiwa kwakawanda kana iyo turbocharger iri kumhanya. Nekudaro, imwe yekuwedzera-nzira vharuvhu inosanganisirwa muEVAP system, iyo inogoneswa uye inotumira huni dzemafuta kana mudziyo wacho uchinge waputirwa mune yakawanda yekudyira kana mune iyo compressor inlet iri pasi pesisitoni kumanikidzwa.

Mibvunzo nemhinduro:

Sei crankcase magasi achionekwa? Nekuda kwekupfeka kweboka repiston. Kana o-mhete yapera, compression inosvina mamwe magasi mu crankcase. Mune injini dzemazuva ano, iyo EGR system inotungamira magasi akadaro kune mushure mekupisa muhumburumbira.

Nzira yekutarisa crankcase magasi nenzira kwayo? Kuonekwa kwemafuta emafuta mumhepo sefa, zvisimbiso zvemafuta uye panosangana chivharo chevhavha, mitsara yemafuta inooneka, mitsetse yemafuta pamutsipa wekuzadza uye pachivharo chevhavha, utsi hwebhuruu kubva pakubuda.

Sei crankcase ventilation ichidikanwa? Iyi sisitimu inoderedza kubuda kwezvinhu zvinokuvadza (musanganiswa wemafuta, gasi rekupedza uye mafuta asina kupiswa mumhepo) nekuda kwekutsva kwavo mumasilinda.
