Gyaran injin. Menene mafi kyawun abin yi?
Mahimmin hanyar
Soot da adibas mai mai da ke daidaitawa akan rukunin piston yana haifar da sakamako mara kyau.
- Rage motsi na matsawa da zoben goge mai. Wannan ita ce babbar matsala. Abin da ake kira "coke" a cikin mutane yana toshe ramukan piston a ƙarƙashin zobba, makullin zobe da tashoshin mai. Wannan yana haifar da raguwar matsawa, ƙara yawan amfani da mai don sharar gida, kuma gabaɗaya zai haɓaka lalacewa na rukunin Silinda-piston (CPG).
- Matsakaicin matsi yana canzawa. Akwai lokuta lokacin da kauri na coke ɓawon burodi a saman saman piston ya kai 2-3 mm. Kuma wannan mahimmanci ne mai mahimmanci, wanda ke ƙara yawan matsawa a cikin silinda. Tare da karuwa a cikin rabon matsawa, yuwuwar fashewar man fetur yana ƙaruwa tare da duk sakamakon da ya biyo baya.
- Ƙarfin canjin zafi yana raguwa. Adadin Coke akan kambin piston da a cikin tashoshi na zobe suna lalata canjin zafi. Piston yayi zafi saboda yana yin sanyi sosai akan bugun bugun lokacin da wani sabon sashe na iska ya shiga cikin silinda. Bugu da ƙari, ƙananan zafi yana canjawa wuri ta hanyar zobe zuwa layin silinda. Kuma idan injin yana da matsala game da tsarin sanyaya, ko da ɗan zafi zai iya haifar da nakasar zafi ko ƙonewar piston.
- Yana ƙara yuwuwar matosai masu haske. Ƙaƙƙarfan hydrocarbons a cikin mazugi na thermal na walƙiya kuma a saman fistan sun zama zafi kuma suna samun ikon kunna cakuda man-iska har sai tartsatsi ya bayyana.
Don cire tsayayyen adibas mai mai daga sassan CPG, an ƙirƙiri kayan aiki na musamman: decoking. Akwai hanyoyi guda uku don isar da decarbonizers zuwa rukunin piston:
- kudaden da aka zuba kai tsaye a cikin ɗakunan piston ta hanyar rijiyoyin kyandir;
- mahadi da aka kara da man fetur;
- decarbonizers da aka gauraye da man fetur.
Akwai decarbonizers, yin amfani da abin da aka yarda da kai tsaye da kuma ta man fetur da lubricants.
Wane magani ya fi kyau?
Wace hanya ce mafi kyau don lalata injin? Yi la'akari da wasu shahararrun kayan aikin da ake amfani da su don wannan dalili.
- Dimexid (ko dimethyl sulfoxide). Da farko dai, maganin ya samo aikace-aikacensa a fagen gyarawa da kuma kula da injunan konewa na ciki. Dimexide yana rushe rarrabuwa da kyau. Ana zuba duka biyu kai tsaye a cikin silinda ta rijiyoyin kyandir ko ramukan bututun ƙarfe, kuma a cikin man injin. Wani lokaci ana amfani da shi azaman ƙara mai. Dimethyl sulfoxide za a iya amfani da shi kawai bayan cikakken nazarin tambaya: shin wannan kayan aiki ya dace da injin ku na musamman. Wannan abun da ke tattare da sinadarai ne. Bugu da ƙari, sludge, yana sauƙaƙe fenti, wanda a cikin wasu injuna yana fentin saman ciki na toshe, pallet da wasu sassa. Duk da haka, rikitarwa na aikace-aikacen da kuma buƙatar yin nazari mai zurfi game da batun yana biya tare da inganci da ƙananan farashi. A ka'ida, wannan ita ce hanya mafi arha don yin ado.
- Hado. Wannan masana'anta yana samar da nau'ikan abubuwa guda uku don tsaftace sassan CPG:
- "Anticox" - hanya mafi sauƙi kuma mafi arha kai tsaye (zuba cikin cylinders);
- Decarbonizer Verylube - shima ana amfani dashi kai tsaye;
- Total Flush - yana tsaftace tsarin mai gaba ɗaya, gami da sassan CPG.
Xado decarbonizing abun da ke ciki sun tabbatar da kansu da kyau. A matsakaicin farashi na kasuwa, duk waɗannan takalmin gyaran kafa aƙalla ba su da amfani, kuma kusan duk masu ababen hawa suna lura da tasirin amfani da su.
- Lavr. Hakanan yana samar da nau'ikan injin decarbonizer da yawa. Abubuwan da aka fi amfani da su na aikin kai tsaye ML202 da ML. Hakanan akwai zaɓin kumfa "Express" don tsaftacewa da sauri. An kiyasta ingancin kowane hanya a cikin mahallin masu ababen hawa a matsayin matsakaici.
- Abubuwan da ake buƙata na decarbonizer Fenom 611N. Kayan aiki mara tsada wanda ke jure wa ƙananan adibas kawai. Ana amfani da shi musamman don rigakafi.
- Wynns Konewa Chamber Cleaner. A zahiri an fassara shi azaman "mai tsaftace ɗakin konewa". Kudinsa kusan iri ɗaya ne da Lavr kuma yana aiki tare da inganci kwatankwacin abun da ke cikin gida. Ba kasafai ake samun su a kasuwannin Rasha ba.
Daga cikin sinadarai na mota don decarbonization, dangane da ingantaccen aiki, wata doka mai sauƙi ta shafi: mafi tsada samfurin, da sauri da kuma yadda ya kamata ya kawar da ajiyar sludge daga sassan CPG. Sabili da haka, lokacin zabar, yana da mahimmanci don tantance ƙimar gurɓataccen pistons kuma, bisa ga wannan ma'auni, zaɓi abun da ake so.
