Valve kufefetedza kuti crankcase magasi kwemarudzi mudziyo musimboti oparesheni

Nepo injini ndiyo anokudzwa kwete chete nokuda chiutsi magasi. vanhu vashoma vanoziva pamusoro crankcase. In yepazasi chikamu injini vaunganidza mafuta mhute, mafuta uye mvura. kuwanda kwavo Zvinoipisisa uye destabilizes injini basa. Kubvisa zvinhu izvi motokari mamiriro inopiwa crankcase kufefetedza vharafu. Touareg ari vakapakata navo zvakare. Chii chaikosha ichi uye kuti inoshanda sei? Mhinduro mimwe mibvunzo iyi uye vazhinji uchaverenga mu nyaya yedu nhasi.

mamiriro

Cherechedza kuti crankcase kufefetedza gadziriro rinoshandiswa kwenguva refu. Musimboti basa rake riri nyore - mukati injini zvakabatana kuti chiutsi zhinji ine hosipaipi. Pasi pokudzora kwomudzimu Vacuum mauto vaunganidza mumafuta muinjini uye mvura vapor vanobviswa kunyika yaunodya turakiti.

On motokari BMW crankcase kufefetedza vharuvhu akaronga kuti magasi kufamba mune mirayiridzo imwe chete.

mhando

Kune mhando mbiri idzi nehurongwa:

• Open.
• Kuvharwa.

Yokutanga mhando yakashandiswa pamusoro injini vakwegura. Pakanga kuitwa kufefetedza pachifunhiro charo lifters kuburikidza zvinoyerera nenyere. magasi All vakanga kupukunyuka kunze injini mupanda. The hurongwa raiva basa, saka mukupera 70s yemotokari vagadziri vakatanga kushandisa namahwindo vharuvhu kufefetedza kuti crankcase magasi. "Opel" ndozvakaitikawo. Zvakanakira ino ndeinotevera:

• It akazoita pachiyero choutsi kuti mhepo.
• The Injini havana kunzwa "nenzara" uye akatsiga chero kumhanya, achipa zvaida huru.
• Achidzikisa kumanikidzwa mukati crankcase. Izvi zvakabatsira kuti dzimwe zviwanikwa zvisimbiso gaskets (mu pachena hurongwa vanongotevera Mabhuku eBraille).

Also kusiyaniswa mhando mavharuvhu gasi nzira yokubudisa kupinda yaunodya zvawanda. Pane kuramba-aibuda vharafu kufefetedza kuti crankcase magasi uye vanomanikidzwa mhando. On motokari "Volga" pamwe injini ZMZ-peturu mhute nzira yokubudisa 402 rikaenda kuburikidza gobvu mafuta nenyere. Akabatana vharuvhu chifukidziro pamwe kabhureta. The zvichiguma magasi vanopiwa zvakananga vakapinda yaunodya siyana pasina kukanganisa vaiitawo mugove huni mhepo nezvakasanganiswa.

mudziyo

Zvino motokari inoshandiswa kufefetedza vharafu crankcase membrane. Inoitwa zvinotevera zvinhu:

• Kufukidza.
• Hwidibiro.
• Dzorera chitubu.
• Housing.

In yokupedzisira pane 2 nechimwe. Chimwe ndechokuti vachigovera crankcase magasi, wechipiri - rokubviswa.

Ungazviita sei?

The mashandiro chiito kunobva uchishandisa pfungwa. Saka muffled injini vharuvhu pasi simba kudzoka kwematsutso chakafukidzwa pedyo membrane. Kana mumuchina idling, kuti diaphragm chinokunda muchirimo simba (sezvo yakaumbwa muna Vacuum ino) uye mugove gasi anopinda Inlet zvawanda. Uyezve, havana pamwe nemafuta-mhepo muvhenganiswa mukamuri afterburned uye outputted kune mhepo. At aimhanya zvinopfuura chimwe namazana mashanu mugero vakasununguka chose diaphragm. Saka, nokurohwa-ne magasi kupinda Inlet zvawo. Nemhaka Kamudzira, havazokwanisi kukwanisa kudzokera kupinda crankcase.

How kuongorora

Sezvo kushanda crankcase kufefetedza vharafu anotanga kuzadza. Zvisinei, izvi hazvirevi kuti chinhu yakarega kushanda uye anofanira kutsiviwa. Kuongorora kana chakaremara crankcase kufefetedza vharafu, zviri akochonorwa kubva injini zhinji uye Chiso chinopenya mune rimwe divi. On the basa mashandiro mhepo negwara kuti asunungurwa mune vhoriyamu duku.

Pane imwe nzira sei kuona kufefetedza vharuvhu kuti crankcase magasi. Nokuti ichi uye otanga injini iri akochonorwa kubva Inlet chubhu, pashure wopedzisa kusunungura kiramba payo. Uyezve, napagumwe roruoko rinoshandisirwa chakakodzera. Zvakakodzera vharafu, inofanira kuomerera. Izvi zvinoratidza kuti pane Vacuum munyika.

Vamwe chirwere uye mamiriro ezvinhu injini pachayo iri vharuvhu. Saka, pakati hosipaipi uye Inlet zhinji maronda läpinäkyvä mafuta Sefa (a carburetor akatasva injini). Kwapera nguva uchava mafuta uye chin'ai. Kana Sefa wakasviba kuti 100-150 makiromita rokutanga, ipapo injini kutadza boka humburumbira-pisitoni. Kunyange hurongwa yakagadzirirwa riparadzirwe zvinokuvadza kuburikidza vharuvhu haafaniri kufamba tsvina yakawanda yakadaro pfupi.

zvinogoneka pazvitadzo

Kana hurongwa haisi Vacuum uye magasi usaswedera kupinda yaunodya siyana, chikonzero - mumwe maviri:

• Vainyeperwa crankcase kufefetedza vharafu.
• Paiva blockage ari hosipaipi hurongwa.

Mukupera nyaya, chikuru chinokonzera dambudziko iri kusakara boka pisitoni. Zvinokosha pakuongorora compression ari sepombi. Uyewo tarisa itsvedzerere marin'i. Kana vari anongoremberera kana "akarara pasi" mafuta vachapinda hurongwa zvizhinji. Kuitika zakoksovka hoses. Pamwe ichi vharafu Kamudzira pacharo raputsika. Fani iyi sei nengozi? Kana hurongwa havagoni zvakanaka kupomba gasi, vachavaka kuvaka dzimwe nzvimbo, uye pasi zvikuru. Saka, havana nepavaigona gaskets uye zvisimbiso. The Injini rakarasika vaise, zviri kusagadzikana idling.

Kana compression rakarurama uye hoses havasi tsinga, vharuvhu pachayo mhosva. Pakadaro, sezvachiri zvakakwana kutsiva itsva.

mutengo

How zvikuru anoita vharuvhu kuti kufefetedza crankcase magasi? "BMW" riri vakashongedzerwa aine mudziyo nokuda 2-2,5 zviuru rubles. On motokari "Ford Focus" chinhu ichi kunokosha mumwe nehafu chiuru rubles. On the zvipfuwo tumabhodhoro netumidziyo vharuvhu haasi munopfuura chiuru.

How kutsiva nemaoko ako?

Ngatikurukurei sei kuchinja basa chinhu vakazvimiririra Somuenzaniso, injini "BMW" M-54. Saka, kutanga unofanira kuwana kurova-rova kufefetedza kuti crankcase magasi. Riri pamberi injini, pasi kudya zvawanda. Svika nayo, kubvisa regulator usimbe uye zvemagetsi throttle. Zvivanakire, anogona kubviswa uye kudya kuzhinji pacharo (asi kwete).

Zvino patsanura kuti hosipaipi kubva vharuvhu mutsigiro nomudonzvo, kusvina pacharo nechokunze maatomu akafanana. Installation mumwe mudziyo mutsva nekwekupedzesera. Kuti vave vakachengeteka, hoses vose wakaiswa pamwe okusungisa.

mhedziso

Saka isu afunga kuti vharuvhu unoshanda uye kufefetedza kuti crankcase magasi. In nokushanda motokari vanofanira nguva nenguva ongorora mamiriro raiva pedyo nebundu iri. Pashure pezvose, kana vharuvhu blockages vanogona "kuwana" yokutsiva zvisimbiso uye gaskets. Ichi mamwe mari mari uye nguva. Onawo kuti kana paiva tsinga hosipaipi, pakuchenesa chete hazvizi shoma. Kana uine nezvinetso pisitoni, chin'ai achiumbwa pezvizuva. Kuchovha aine atadze kushanda zvakanaka kwakadaro haisi inokurudzirwa. Handiti, kwokudzvinyirira iri crankcase kanoverengeka kupfuura dzose. Zvakakosha kuongorora injini compression, uye kana zvichiita - hurumende mafuta marin'i.
