A farkon inji shi kamar haka: daga crankcase sauki ƙarshe tube, samar da gas a cikin yanayi da kuma ƙazantar da shi. Amma da dokoki a kan a saki gas daga motocin mai tsanani tsaurara. Saboda haka, crankcase iska tsarin da aka ɓullo da ƙ da masana'antun.

The manufa inji na mataki

A cikin irin a cikin abin da tsarin da aka sani a wannan lokacin, ba kawai gas ake jefarwa cikin yanayi. Ana aika zuwa ga mota ta cikin bututu janye daga sump, da sauran karshen wanda aka haɗa da ci da yawa. Daga can gas an directed a cikin konewa jam'iyya. A flash batu na su ƙone da sauran part aka sallami ta hanyar wani shaye inji. Sai kawai karamin rabo daga wadannan gas sake shiga cikin crankcase. Tun da aiwatar faruwa ba tare da katsewa.

Nau'in sump recirculation tsarin

Akwai iri biyu na tsarin:

• waje.
• rufaffiyar.

A cikin farko idan, kamar yadda aka ambata da farko, da gas ta sallami zuwa sararin sama kawai. A karo na biyu da ake sucked cikin ci wuriyar. An Rufe crankcase iska tsarin: Vaz da kuma "Lada", BMW da "Mercedes", da Japan da kuma jama'ar {asar Amirka ne, yafi amfani a halin yanzu.

Bugu da kari, a rufe tsarin ne samuwa tare da AC ko DC halin yanzu. Nau'i na farko shi ne m na tsakaita more daidai da recirculation sump. Yana dabam dangane da adadin masu shigowa gas.

A saman SEPARATOR ne crankcase iska tsarin da ciki da man - da reflector. Its aiki ne don ya saki gas daga mai barbashi. PCV mai SEPARATOR yana da wani kanti zuwa wuriyar. A al'ada aiki da engine crankcase m wasu injin ya kamata faruwa. A bawul iya aiki a uku embodiments.

Tilasta crankcase iska tsarin: bawul

Bari mu bincika a ta aice duk uku daga cikin wadannan zažužžukan.

1. Domin da maƙura aka kafa ta low matsa lamba 500 zuwa 700 mbar. crankcase iska tsarin, wannan ba zai tsaya. Kuma da fistan karkashin mataki na injin, rufe bawul.
2. Idan maƙura ne cikakken bude, da matsa lamba akwai daidaita yanayi ko mafi girma. Bayan kai 500-700 mbar fistan rufe bawul ga nassi na gas.
3. A cikin tsakiyar matsayi da aka bayar da al'ada matsa lamba fistan.

Idan bawul aikin kiwata tambayoyi, shi ne mai sauki duba serviceability. Don wannan karshen, idling a wuyansa, wanda aka cika da mai, sanya a takardar da takarda. Idan an saukar da tashe tare da motsi na da diaphragm, bawul din ne serviceable.

Al'ada aiki za a iya tabbatar da su ta wata hanyar. A rago yanayin, cire iska tiyo da kuma rufe yatsa kamata jin tsotsa.

Matsa lamba rage bawul

Idan mota aiki a high gudu, da ci da yawa matsa lamba ne akwai, cewa yana da darajar daidaita da na yanayi, ko kuma ya wuce shi. A wannan yanayin, da crankcase gas samun daina. Idan mashiga ruwa yana mai turbocharger, da wuri zai zama ma manyan kuma ya zama balance.

Don wannan karshen, shi na samar da wani matsin lamba rage bawul, wanda aiki a ci da yawa a lokacin da bawul yana buɗewa. Inji kunshi wani membrane da kuma bazara da aka saka a cikin roba mahalli, a cikin abin da akwai mashiga ruwa da kanti kayan aiki.

Aiki matsa lamba rage bawul

A al'ada low-matsa lamba spring aka ɗora Kwatancen. A membrane ne tãyar da gas sun shige da yardar kaina.

Karkashin rage matsa lamba, da diaphragm aka saukar da rufe kanti da spring mataki. Sa'an nan da gas fara don motsawa ta cikin detour - tashar tare da calibrated bude.

Abin baƙin ciki, mukaddashin gaskiya ma a hannu daya, da crankcase iska tsarin halitta matsala tare da sauran. Fitowa daga cikin pallet, da gas kama da lubricating gaɓũɓuwa, haka gurbata da ci tsarin. Bugu da ƙari kuma, suna ajiye a saman na fita tashoshi, da kuma cikakken bayani na maimaita bawul. Wannan take kaiwa zuwa takaita na tashar kuma zai iya sa malfunctions a cikin allura. Idan Iris ne matsattse, da mai amfani zai kara. Sa'an nan wajibi ne a canza bawul.

Har ila yau kada ka manta game da wasu muhimman bayanai, da kuma lokacin da za a canza crankcase iska tiyo - wannan mafi yawa ana yi a tare da recirculating bawuloli. In ba haka ba, shi fasa da kuma karya.

Don kauce wa m gyare-gyare, shi wajibi ne don kula da kunno kai spots a kan engine like, da kara amfani da habaka da lubricating ruwa da kuma m aiki na engine. Idan lokacin ya fitar da wani sabis, matsalar za a warware a cikin toho, har sai da ta bai sa gwaji lalacewar da naúrar.
