Iyini isimiso somsebenzi wophawu lwamafutha e-valve yemoto?
I-valve yenjini iwuphawu olubalulekile lokuvala injini. Umsebenzi walo oyinhloko ukuvimbela uwoyela wenjini ukuthi ungangeni ku-input manifold, ipayipi lokukhipha umoya, kanye negumbi lokushisa, kanye nokuvimbela ukuvuza kwegesi exubile kanye namagesi okukhipha umoya, ngaleyo ndlela kuqinisekiswe ukusebenza kokuvala kanye nokusebenza okuvamile kwengaphakathi lenjini.
Isimiso sokusebenza sincike kakhulu ekwakhiweni kwesakhiwo okuyingqayizivele kanye nezakhiwo zezinto ezibonakalayo. Imininingwane imi kanje:
Indlela yokuvala: I-valve oil seal ifakwe eduze kwesiqu se-valve futhi isekelwa uhlaka lwangaphandle ukuqinisekisa ukuthi i-oil seal ayiguquguquki ngaphansi kokushisa okuphezulu kanye nokucindezela okuphezulu; ingxenye ye-radial ifakwe isiphethu esiziqinisayo noma ucingo lwensimbi, olungahlala lunamathele ebusweni besiqu se-valve, lwakha uphawu oluguquguqukayo. Ngisho nangesikhathi sokuvulwa nokuvalwa njalo kwe-valve, ingavimbela ngempumelelo ukuvuza kwamafutha enjini eceleni kwesiqu.
Izakhiwo zezinto: Umzimba oyinhloko wesivalo sikawoyela uvame ukwenziwa nge-fluororubber, enezakhiwo ezinhle kakhulu zokumelana nokushisa okuphezulu kanye nokumelana nokugqwala kukawoyela, futhi ingagcina ukuqina nokusebenza kokuvala endaweni yenjini enamazinga okushisa afinyelela ku-degrees Celsius angamakhulu amaningana, imelane nokuguguleka kwamakhemikhali kawoyela wenjini.
Inqubo yokusebenza: Uma ivalvu ivaliwe, uphawu lukawoyela lwevalvu luba sesimweni sokuvalwa, okuvimbela uwoyela wenjini ekamelweni levalvu ukuthi ugelezele phansi ungene ekamelweni lokushisa noma ukhuphuke ungene emapayipini okungenisa kanye nawokukhipha umoya; lapho ivalvu ivuleka, uphawu lukawoyela luhamba nevalvu, kodwa luthembele esakhiweni esiziqinisayo ukuze luqhubeke nokunamathela, luqinisekisa ukuthi uphawu aluphazanyiswa.
Uma uphawu lwe-valve oil luguga noma lonakele, uwoyela wenjini uzongena ekamelweni lokushisa bese ushiswa, okubangela izinkinga ezifana nokushisa uwoyela wenjini, intuthu eluhlaza okwesibhakabhaka evela epayipini lokukhipha umoya, ukwanda kwe-carbon deposits, kanye namandla anciphile. Ngakho-ke, ukuhlolwa njalo kanye nokufakwa kwe-valve oil oil seals ngesikhathi esifanele kubaluleke kakhulu ekugcineni ukusebenza kanye nokuphila kwesikhathi senjini.
Ukwehluleka kophawu lwamafutha e-valve yenjini kubhekisela ekugugeni, ekulimaleni, noma ekwehlulekeni kophawu lwamafutha e-valve, okubangela ukuba uwoyela wenjini ungene ekamelweni lokushisa futhi uhlanganyele enqubweni yokusha, ngaleyo ndlela kubangele uchungechunge lwezimo ezingavamile. Nakuba uphawu lwamafutha e-valve luncane, umsebenzi walo ubalulekile. Uma lonakele, luzothinta ngqo ukusebenza kwenjini kanye nesikhathi sokuphila kwayo.
Izimpawu eziyinhloko zokwehluleka kokuvalwa kwe-valve oil
Intuthu eluhlaza okwesibhakabhaka evela emthonjeni wokukhipha umoya: Lolu uphawu oluvame kakhulu. Lapho injini iqala, ingasebenzi, noma ishesha ngokuzumayo, ipayipi lokukhipha umoya lizoqhubeka nokukhipha umusi oluhlaza okwesibhakabhaka, okuyisici sokusha okungaphelele kukawoyela wenjini.
Ukusetshenziswa kukawoyela okusheshiswe ngendlela engajwayelekile: Ngaphandle kokuvuza okusobala, izinga likawoyela lehla kakhulu esikhathini esifushane (njengangaphakathi kwamakhilomitha ayizinkulungwane ezimbalwa), futhi uwoyela wenjini udinga ukugcwaliswa njalo.
Amadiphozithi amakhulu ekhabhoni kuma-spark plugs: Ngemva kokuba uwoyela wenjini ungene ekamelweni lokushisa, uzokwakha amadiphozithi amnyama, anamafutha ekhabhoni kuma-electrode e-spark plug, okubangela ukushaqeka okubi kanye nokuqala kokuzamazama kwenjini, ukungahlaliseki kahle, noma ukulahlekelwa amandla.
Amandla enjini ancishisiwe, ukusheshisa okubuthakathaka: Ngenxa yokusebenza kokuvala kwesilinda okuncishisiwe, ukucindezela okwanele kokucindezela, kanye nokusebenza kahle kokushisa okuncishisiwe, imoto izobonisa ukusheshisa okuhamba kancane kanye nokukhipha amandla okunganele.
Amabala kawoyela noma umswakama endaweni yokukhipha uphethiloli: Izinsalela ezifana namafutha noma amamaki amanzi angabonakala endaweni yokukhipha uphethiloli, ehambisana nephunga elimnandi likawoyela wenjini.
Intuthu eluhlaza okwesibhakabhaka esobala kakhulu ngesikhathi sokuqala kokubanda: Ngemva kokuguga kokuvalwa kwe-valve oil, uwoyela wenjini uzongena kumhlahlandlela we-valve lapho imoto ipakwe ebusuku, futhi ukuvuza kuba kukhulu uma injini ibanda. Isici sentuthu eluhlaza okwesibhakabhaka sivelele kakhulu.
Izimbangela ezivamile zokwehluleka kophawu lwe-valve uwoyela
Ukuguga kwemvelo: I-valve oil seal ivame ukwenziwa nge-fluororubber noma i-silicone rubber. Ivezwa ekushiseni okuphezulu kanye nokucindezela okuphezulu isikhathi eside, futhi i-raber izoqina, iqhekeke, futhi ilahlekelwe ukuqina, okuholela ekuhlulekeni kokuvala.
Ukuguguleka kwekhabhoni: Ukusetshenziswa isikhathi eside kukawoyela wenjini ongemuhle noma ukushayela ibanga elifushane njalo kungakha kalula amadiphozithi ekhabhoni kumhlahlandlela wevalvu, kugqoke umlomo wesivalo sikawoyela.
Ukuhlanganiswa okungafanele: Uma ushintsha, uma kungekho mathuluzi akhethekile asetshenziswayo, indlela yokufaka ayilungile, noma kungekho uwoyela wenjini ogcotshwe, kulula ukudala umonakalo ku-oyela.
Ukushisa ngokweqile kwenjini noma ukugcotshwa okubi: Izinga lokushisa eliphezulu lisheshisa ukuguga kwerabha, futhi uwoyela wenjini osezingeni eliphansi noma isekethe kawoyela evinjiwe nakho kungabangela ngokungaqondile ukuthi uphawu lukawoyela luhluleke.
Ungabhekana kanjani nokwehluleka kophawu lwe-valve oil?
I-valve oil seal ayikwazi ukulungiswa futhi kufanele ishintshwe.
Isu lokufaka esikhundleni:
Uma konakala izivalo zikawoyela zamavalvu angu-1-2 kuphela, isembozo samavalvu singashiywa singaphazanyiswa, futhi umoya ocindezelekile ungafakwa ngembobo ye-spark plug ukuze ubambe ivalvu, bese kusetshenziswa amathuluzi akhethekile ukuze kufakwe okunye.
Uma amasilinda amathathu noma ngaphezulu enephutha, noma injini ibilokhu iqhutshwa isikhathi eside (njengamakhilomitha angaphezu kuka-100,000), kunconywa ukuqaqa isembozo se-valve sonke, ukufaka esikhundleni zonke izivalo zikawoyela ze-valve ngokulinganayo, nokugwema ukulungiswa njalo esikhathini esifushane.
Izinyathelo zokufaka esikhundleni:
Sebenzisa izingxenye zokuqala noma ezisezingeni eliphezulu (izinto ze-silicone ezinconywayo, ukumelana nokushisa okungcono).
Inqubo yokufaka esikhundleni idinga imishini nobuchwepheshe bochwepheshe. Kunconywa ukuthi isetshenziswe yisitolo sokulungisa esivamile ukuze kugwenywe ukungcola okungene enjinini noma ukufakwa okungafanele okubangela umonakalo wesibili.
Ngemva kokushintsha, kunconywa ukuthi kwenziwe ukuhlanza ikhabhoni yenjini ukuze kubuyiselwe ukuhlanzeka kwegumbi lokushisa kanye nokusebenza kwamandla.
Iziphakamiso zokuvimbela
Shintsha njalo uwoyela wenjini owenziwe ngokuphelele osezingeni eliphezulu bese ushintsha isihlungi samafutha ngokuya ngomjikelezo onconyiwe ngumenzi.
Gwema ukushayela ibanga elifushane isikhathi eside kanye nokungahlali njalo, okuvumela injini ukuthi ifudumale ngokugcwele, okusiza ukunciphisa ukufakwa kwekhabhoni.
Qaphela ukubheka isimo semoto. Uma uthola ukukhishwa okungajwayelekile komoya noma ukusetshenziswa kukawoyela okusheshayo, hlola ngokushesha.
Isikhathi esijwayelekile senkonzo yesivalo sikawoyela we-valve ngokuvamile siphakathi kwamakhilomitha angu-80,000 no-150,000, kodwa sithinteka kakhulu yindawo yemoto kanye nemikhuba yokulungisa. Uma imoto isondela kuleli mayela, kunconywa ukuthi uyihlole ngenkuthalo ngesikhathi sokulungisa.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
