Crankcase kufefetedza System: A mudziyo mifananidzo, uchishandisa misimboti

Panguva ino, pasinei kukurumidza kukura ruzivo kuti pave rakanamwa zvachose peya kukweshera zvikamu - humburumbira uye pisitoni zvindori - hazvibviri. Naizvozvo pakupedzisira uchingounganidza ari kushanda zvibereko combustion injini.

The sump crankcase magasi nomunyika pisitoni zvindori, izvo yakabatana sepombi zvakasiyana-siyana. Somugumisiro, kupisa chinobviswa kuipa kupfupiswa oupenyu lubricating emura achiumbwa uye kunyanya kumanikidzwa pamusoro ose chinogumbura chisimbiso. crankcase kufefetedza hurongwa kunodzivisa kunyanya crankcase nevezera.

Kugadzirwa namano

Pakutanga mashoko mashandiro rakanga sezvinotevera: kubva crankcase nyore mhedziso chubhu, uchibereka magasi mumhepo uye vaisvibise ndizvo. Asi mitemo iri nokubudiswa magasi motokari zvikuru akasungirirwa. Naizvozvo, kuti crankcase kufefetedza hurongwa yakazokudziridzwa nechomukati kubudikidza vagadziri.

Nhungamiro mashandiro chiito

Muchimiro umo hurongwa rinozivikanwa panguva, kwete chete magasi vari chaibwinya mumhepo. Vari akatumira injini kubudikidza chubhu vakabviswa sump, mumwe mugumo iyo zvakabatana ari kudya zvawanda. Kubva ipapo magasi tinotungamirirwa muimba combustion yomukati. The mbaravara Pfungwa wavo vakapisa uye chimwe chikamu chiri asunungurwa achishandisa chiutsi mashandiro. chiduku inorwara magasi aya chete zvakare anopinda crankcase. Sezvo muitiro kunoitika pasina kuvhiringidzwa.

Types sump recirculation hurongwa

Kune mhando mbiri nehurongwa:

• kunze;
• up.

Muchiitiko chokutanga, sezvarondedzerwa pakutanga, kuti magasi asunungurwa kuti mhepo nyore. In wechipiri vari vakanwa vakapinda yaunodya rukoronga. Closed crankcase kufefetedza maitiro: Vaz uye "vakanciq", BMW uye "Mercedes", Japan uye vokuAmerica dzinowanzotsigi- kushandiswa pari.

Uyezve, akadzivira hurongwa anowanikwa pamwe AC kana DC ano. Chokutanga mhando anokwanisa kudzora zvikuru zvakarurama recirculation sump. It dzinosiyana zvichienderana uwandu kuuya gasi.

mudziyo

Panguva pamusoro separator ndiwo crankcase kufefetedza maitiro uye mukati namafuta - the reflector. Basa racho kusunungura magasi kubva nezvimedu mafuta. PCV mafuta separator ane nzira yokubudisa kuna rukoronga. Chaiye oparesheni injini crankcase chenguva vamwe Vacuum ikaitika. The vharafu unogona kushanda nenzira embodiments matatu.

Kudzosera crankcase kufefetedza hurongwa: Valve

Ngatikurukurei muchidimbu zvose zvitatu izvi zvaramba.

1. Nokuti throttle chakaumbwa yakaderera kumanikidzwa 500 kusvika 700 mbar. crankcase kufefetedza gadziriro, ichi haingamiri. Zvino pisitoni pasi Zvakaitwa Vacuum, rinogumisa vharuvhu.
2. Kana throttle anonyatsokwanisa rakazaruka, kumanikidza pane akaenzana ratinoona kana yakatokura. Paaizosvika 500-700 mbar pisitoni anovhara vharuvhu nokuda kwemutemo magasi.
3. pakati nzvimbo inopiwa kwomuzvarirwo kumanikidzwa pisitoni.

Kana vharuvhu basa zvinomutsa mibvunzo, zviri nyore kuti tione serviceability. Kuti izvi zvidaro, idling pamutsipa, iyo yazara namafuta, akaisa papepa. Kana havachakoshesi uye akamutswa pamwe kwebasa diaphragm, vharuvhu riri basa.

Normal inoshanda inogona achasimbiswa nedzimwe nzira. In simbe nzira, bvisa kufefetedza hosipaipi uye kuvhara munwe vanofanira kunzwa kubvisa.

Pressure kuderedza vharafu

Kana injini unoshanda panguva dzakakwirira aimhanya, ari kudya zhinji kufurirwa aripo, kuti ane ukoshi akaenzana mumhepo kana akapfuudza izvozvo. Panyaya iyi, iyo crankcase magasi anowana refu. Kana Inlet ane turbocharger, kuti Vacuum uchakomborerwawo huru uye kuva nomwero.

Kuti izvi zvidaro, inopa nezvinodzvinyirira achidzikisa vharafu, izvo unoshanda yaunodya zhinji apo vharuvhu anovhura. Mashandiro ina Kamudzira uye tsime iri rakapinzwa mapurasitiki kwedzimba, umo mune Inlet uye nzira yokubudisa Fittings.

Basa nevezera kuderedza vharafu

Chaiye pasi-kumanikidzwa chitubu iri akatakura. The Kamudzira amutswa uye magasi hatichamuzivi pachena.

Under akaderedza kumanikidzwa, kuti diaphragm iri akatura uye anovhara nzira yokubudisa pamusoro chitubu chiito. Ipapo magasi vanotanga kufamba kubudikidza dhituwa - mugero ane calibrated buri.

Zvinosuruvarisa kuita zvakanaka kune rumwe rutivi, ari crankcase kufefetedza hurongwa pave dambudziko nevamwe. Vachibuda nhovo, ivo magasi akakunda uye lubricating nezvimedu, nokudaro kusvibisa nyika yaunodya hurongwa. Uyezve, vari rakachengetedzwa pamusoro hukawanika ari mbudo hova, uye mashoko ari Kuzvigadzira Patsva vharuvhu. Izvi zvinotungamirira aienda pamusoro gwara uye zvingakonzera malfunctions ari jekiseni. Kana maziso ari wavharwa, ari mafuta vapera kuchawedzera. Zvino zvakafanira kuchinja vharuvhu.

Uyewo usakanganwa pamusoro mamwe mashoko anokosha, uye nguva yokuchinja crankcase kufefetedza hosipaipi - ichi kunowanzoitwa pachiimbwa recirculating mavharuvhu. Zvikasadaro, makatsemuka uye hwatsvuka.

Kuti tidzivise anodhura kugadziridza, zvakakodzera kuteerera zvichiitika makwapa injini zvisimbiso, kuwedzera kudyiwa rinochiwedzera uye lubricating Urume uye kusagadzikana mudzimu injini. Kana nguva kutyaira kune basa centre, chinetso zvichapedzwa mu chipande, kusvikira iye haana kukonzera nouchapupu kuvadza chikwata.
