Amafutha avuzayo ngaphansi kwesihlungi sikawoyela

Phakathi nokusebenza kwemoto, abashayeli abaningi baqaphela ukuvuza kwamafutha ngaphansi kwesisefo sikawoyela. Le nkinga ingaba efanele kokubili kubanikazi bezimoto ezindala ezinamamayela aphezulu, kanye nezinjini ezivuthayo zangaphakathi.

Esimweni sokuqala, amafutha ageleza azungeze isihlungi samafutha, ngoba ipompo yamafutha yesistimu yokugcoba ingase ingabi ne-valve yokunciphisa ingcindezi engavumeli ukucindezela ngokweqile ohlelweni. Ngokuvamile, inkinga izibonakalisa ngemva kokuqala okubandayo ebusika, lapho uwoyela ushuba ku-crankcase yeyunithi yamandla. Igrisi imane nje ayinaso isikhathi sokudlula esisefweni, okwenza ukuba amafutha akhishwe ngenkani.

Ngezinjini zanamuhla, ukuvuza ngenxa yalesi sizathu ngokuvamile akuvunyelwe, ngoba ukuba khona kwe-valve yokusiza ukucindezela ngokweqile ekwakhiweni kwezinhlelo zesimanje kuqeda lokhu okungenzeka. Ngenxa yalesi sizathu, ukuvuza kukawoyela ngaphansi kwezindlu zokuhlunga uwoyela kungasebenzi futhi kuba isizathu sokuxilonga iyunithi yamandla.

Kulesi sihloko, sizokhuluma ngokuthi kungani amafutha ephuma esihlungini samafutha, yini okufanele uyenze uma ukuvuza kwamafutha kutholakala ngaphansi kwekhava noma izindlu zokuhlunga uwoyela, nokuthi ungayilungisa kanjani.

Kungani uwoyela ugeleza usuka ngaphansi kwesihlungi samafutha

Okokuqala nje, uhlu lwezizathu zokuthi kungani ukuvuza kukawoyela endaweni yokuhlunga uwoyela luningi kakhulu. Ngokuvamile, umlandu ungumnikazi ngokwakhe, ongashintshi isihlungi samafutha isikhathi eside.

• Ukungcoliswa kwesihlungi samafutha ngaphansi kwezimo ezithile kungaholela eqinisweni lokuthi ukusebenza kuncipha kakhulu, i-lubricant empeleni ayidluli endaweni yokuhlunga. Ngesikhathi esifanayo, ukuze kuvikelwe uwoyela indlala injini, umklamo isihlungi ngokuvamile kuba ekhethekile bypass valve (ivumela uwoyela ukudlula isici lemifanekiso), kodwa akunakwenzeka ukuba akhiphe ukuthi kungenzeka ukwehluleka ngesikhathi ukusebenza kwayo.

Esimeni lapho ukuhlanzeka “nokusha” kwesihlungi kungangabazi, amaphutha enziwe ngesikhathi sokufakwa kwaso. Uma ukuvuza kwenzeka ngokushesha ngemva kokufaka isihlungi, kungenzeka ukuthi isihlungi asiqiniswanga ngokwanele noma indlu ayisontiwe (uma kuyisakhiwo esigoqekayo). Lokhu kubonisa isidingo sokuqiniswa. Le nqubo yenziwa ngesandla noma nge-extractor ekhethekile yepulasitiki.

Imfuneko ingabhekwa njengokungabikho komzamo lapho uphenduka, ngoba ukuvinjelwa kuholela ekuqhekekeni kwenjoloba yokuvala uphawu kanye nokuguqulwa kwendandatho yokuvala. Kulokhu, kuyadingeka ukufaka isihlungi esikhundleni esisha noma ukuxazulula inkinga ngokufaka uphawu olonakele.

Sengeza ukuthi kaningi ngesikhathi sokufakwa, abanikazi bezimoto kanye noomakhenikha bayakhohlwa ukugcoba i-o-ring endala yerabha endaweni yesihlungi samafutha ngamafutha enjini. Lokhu kuholela eqinisweni lokuthi ngemva kokukhulula isihlungi, singase sikhululeke, uphawu lungakhubazeka noma lubekwe lugwegwile.

Kunoma yikuphi, isihlungi sikawoyela kufanele sisuswe, ubuqotho bophawu buhlolwe, ibhande lenjoloba eligcotshiwe futhi kushintshwe isici sokuhlunga, kucatshangelwa izici ezingavamile zokufakwa kwayo. Kufanele futhi kukhunjulwe ukuthi isihlungi samafutha esingalungile singatholakala ngokuthengiswa. Esimweni esinjalo, izindlu ngokwazo zingase zibe nephutha, lapho kukhona ukuqhekeka, uphawu lungenziwa nge-rubber yekhwalithi ephansi, i-valve yokuhlunga ayisebenzi, njll.

Umfutho kawoyela wenjini ephezulu iyimbangela yesibili evame kakhulu yokuvuza kukawoyela eduze kwesihlungi sikawoyela. Ukwanda kwengcindezi ohlelweni lokuthambisa kungase kwenzeke ngenxa yezizathu eziningi, kusukela ekuqinisweni okuphawulekayo kwe-lubricant, okuhambisana namazinga kawoyela amaningi, kuya ekuhlulekeni okuthile kwemishini.

Ake siqale nge-valve yokudlula. I-valve eshiwo iyadingeka ukuze unciphise ukucindezela kwamafutha uma kwenzeka kudlula inani elishiwo. I-valve ingatholakala endaweni yesibambi sokuhlunga, kanye nasepompo lamafutha ngokwalo (kuye ngokuthi izici zokuklama). Ukuze uhlole, udinga ukufika ku-valve futhi uhlole ukusebenza kwayo.

Uma ibambeka endaweni evaliwe, i-elementi ayisebenzi. Kulokhu, idivayisi kufanele ihlanzwe futhi ihlanzwe. Ukuhlanza, uphethiloli, i-carburetor cleaner, i-parafini, njll. Sicela uqaphele ukuthi, njengoba umkhuba ubonisa, kungcono ukushintsha ama-valve uma kungenzeka, ikakhulukazi uma ucabangela intengo yayo engabizi kakhulu.

Esinye isizathu sokuvuza kwesihlungi sikawoyela inkinga ngezintambo zokufafa lapho isihlungi sijikijelwa khona. Uma izintambo zihlutshiwe noma zonakalisiwe, indlu yokuhlunga ayikwazi ukuqiniswa kahle ngesikhathi sokufakwa, futhi amafutha azophuma ngenxa yalokho. Esimweni esinjalo, kuyadingeka ukushintsha isesekeli noma ukusika intambo entsha.

Kumele futhi kuqashelwe ukuthi uma uwoyela ekhethiwe ngokungalungile, okungukuthi, uba uketshezi kakhulu noma i-viscous, khona-ke ukuvuza kuvame ukwenzeka endaweni yama-gaskets nezimpawu. Isihlungi sikawoyela asinjalo. I-lubricant kufanele ikhethwe ngokuhambisana nezidingo zomkhiqizi wemoto, futhi icabangele izici nezimo zokusebenza.

Sicela uqaphele ukuthi uma umshayeli ehlala esebenzisa uhlobo olufanayo lwamafutha, isihlungi asingcolile, kwakungekho izinguquko eziphawulekayo ezimweni zezulu, futhi akukho ukungasebenzi kahle kwenjini, khona-ke uwoyela wenjini-mbumbulu ungase ugcwale injini. Kuvela ukuthi amafutha asezingeni eliphansi awanazo izinto ezimenyezelwe, yingakho ukuvuza kuvela.

Indlela yokuphuma kulesi simo isobala: kuyadingeka ukuthi ushintshe isihlungi kanye ne-lubricant ngokushesha, futhi kungase kudingeke futhi ukuhlanza okwengeziwe kwesistimu yokugcoba injini. Ekugcineni, sengeza ukuthi ukuvaleka kwamapayipi ohlelo lokungenisa umoya we-crankcase kubangela ukunqwabelana kwamagesi ngaphakathi kwenjini evuthayo yangaphakathi, ukwanda kokucindezela ngaphakathi kwenjini nokuvuza kukawoyela ngokusebenzisa ama-gasket nama-seal. Isistimu yokungenisa umoya ye-crankcase eshiwo kufanele ihlolwe phakathi nenqubo yokuxilonga, futhi ihlanzwe ngezikhathi ezithile ngezinjongo zokuvimbela.

Indlela yokulungisa ukuvuza kwesihlungi samafutha

Ngakho-ke, ezimweni eziningi, kwanele ukugcwalisa uwoyela wekhwalithi ephezulu, ngokucabangela izincomo zomkhiqizi kanye nenkathi yonyaka, ukuze ushintshe kahle noma ufake isihlungi samafutha.

Ngamakhono ayisisekelo, kungenzeka ukuthi ubhekane nokuhlanza uhlelo lokungenisa umoya we-crankcase. Lokhu kusho ukuthi ezimweni eziningi, cishe wonke umshayeli egaraji angalungisa ukuvuza kwamafutha ngezandla zabo.

Ngokuqondene nokuqhekeka okuyinkimbinkimbi okwengeziwe, lokhu kuhlanganisa i-valve yokunciphisa ingcindezi enephutha kanye nezintambo ezilimele ekufakeni isihlungi sikawoyela. Eqinisweni, inkinga nge-valve ivame kakhulu, ngakho-ke ake sigxile ekuyihloleni ngokwehlukana.

Umsebenzi oyinhloko ukuhlola isiphethu se-valve, esitholakala ngaphansi kwepulaki. Nguye obhekene nokusebenza kwedivayisi, ukusebenza okuphelele kuzoxhomeka esimweni sentwasahlobo. Intwasahlobo eshiwo kufanele ikhishwe emkhonweni ukuze ihlolwe. Ukuklwebheka, imibimbi, ukugoqa nokunye ukukhubazeka akuvunyelwe. Futhi, intwasahlobo kufanele iqine, ingakhululeki.

Uma isiphethu sinwetshwa kalula ngesandla, lokhu kukhombisa ukuba buthakathaka kwalesi sici. Ngaphezu kwalokho, ubude obuphelele bentwasahlobo akufanele bukhule, okubonisa ukwelula. Ukuncipha kobude kubonisa ukuthi ingxenye yentwasahlobo iphukile. Kulesi simo, kuyadingeka futhi ukususa imfucumfucu esihlalweni se-valve. Ukuthola noma yikuphi ukukhubazeka entwasahlobo kuyisizathu sokuyishintsha.

Ake sibambe imiphumela

Njengoba ubona, kunezizathu eziningi zokuvuza kwamafutha endaweni yokuhlunga uwoyela. Kuyadingeka ukuhlola injini ohlelweni lokuxilonga ngezigaba, okungukuthi, ngokuqedwa. Ngokuhambisana nokufuna inkinga, ungakwazi ukukala ingcindezi ohlelweni lokuthambisa ngegeji ye-liquid pressure gauge, futhi ulinganise ukucindezelwa enjinini.

Ukuncipha kokucindezela kumasilinda kuzobonisa ukukhululwa okungenzeka kwamagesi avela ekamelweni elivuthayo kanye nokwanda kwengcindezi ku-crankcase. Ukufundwa kwegeji ye-fluid pressure kuzokusiza ukuthi ubone ngokushesha ukuchezuka kwengcindezi ohlelweni lokuthambisa, uma kukhona.

Okokugcina, sengeza ukuthi uma uwoyela ugeleza uphuma ngaphansi kwesihlungi sikawoyela ngesikhathi sokuqala noma i-lubricant igeleza njalo, injini isebenza kanye nokucindezela ohlelweni lokuthambisa kuyinto evamile, futhi isihlungi ngokwaso sifakwe kahle futhi silungiswe ngokuphephile. khona-ke isizathu singase sibe sekhwalithi ephansi yesihlungi ngokwaso. Kulesi simo, ngaphambi kokulungisa injini yomlilo yangaphakathi, kungcono ukuqala ukuguqula isihlungi sibe umkhiqizo oqinisekisiwe ovela kumkhiqizi owaziwayo.
