Uyini umphumela wephedi yekhava ye-valve yegumbi elivuzayo?
01 Kuthinta ukuqina komoya kwenjini
Ukuvuza kwamafutha kuphedi yekhava yegumbi le-valve kungadala umonakalo ekumpintsheni komoya wenjini.Lapho ukuvuza kwamafutha kwenzeka, ingcindezi yokusebenza yenjini izovuza ukusuka lapho, okuzothinta ukuzinza kwenjini.Kukhona i-valve yokukhipha igesi ephumayo exhunywe ku-throttle valve ngaphakathi kwenjini, futhi ukuvuza komoya kuzophazamisa lolu hlelo, ngaleyo ndlela kuthinte ukuqina kokusebenza kwenjini.Ukwengeza, ukuvuza kukawoyela kuphedi yekhava yegumbi le-valve kungase kubangelwe ukuguga kwekhava yegumbi le-valve noma ukuvaleka kwevalvu yokungenisa umoya nge-crankcase.
02 Kuthinta ukukhishwa kokushisa kwenjini
Ukuvuza kwephedi yekhava ye-valve kunomthelela omubi emsebenzini wokukhipha ukushisa kwenjini.Ukuvuza kwamafutha kuzokwenza injini yehlise uwoyela ngaphakathi, okuzophazamisa umphumela wokupholisa injini.Ikakhulukazi ezinjinini ezine-turbocharged, izinkinga zokulahla ukushisa ngenxa yokuvuza kukawoyela zingandisa ingozi yokusha okuzenzakalelayo.Ngakho-ke, uma ikhava yegumbi le-valve itholakala ukuthi ivuza uwoyela, kufanele ilungiswe kusenesikhathi ukuze kugwenywe ukulimala kwenjini nezinye izingozi zokuphepha ezibangelwa ukungashabalali kahle kokushisa.
03 Kuthinta ukugcotshwa kwenjini
Ukuvuza kwamafutha okuvela kuphedi yekhava yegumbi le-valve kuzophazamisa ukugcotshwa kwenjini.Ngokukhethekile, uwoyela ovuzayo ungabangela ukugcotshwa okunganele kwegumbi le-valve.Uma lokhu kuntuleka kokugcoba kuqhubeka isikhathi eside, kuzodala ukuguga kwezingxenye, bese kulimaza injini.Ngakho-ke, kubaluleke kakhulu ukuxazulula inkinga yokuvuza kwamafutha ye-valve yekhava yegumbi ngesikhathi ukuze kuqinisekiswe ukugcotshwa okuvamile kwenjini futhi kwandise impilo yayo yesevisi.
04 Injini ilimele kakhulu ngenxa yokushoda kukawoyela
Ukulimala okukhulu kwamafutha enjini kungaholela ezinkingeni ezihlukahlukene, enye yazo ukuvuza kwe-valve chamber pad oil.Lolu hlobo lokuvuza kwamafutha alugcini nje ngokudala ukungcola kwenjini, kodwa futhi lungase luqale umlilo.Amafutha avuzayo azohlangana nothuli enze udaka, futhi lapho ehlangana nelangabi elivulekile, angase okhele injini, okubangele izingozi ezinkulu zokuphepha.Ngakho-ke, uma i-gasket yekhava yegumbi le-valve kutholakala ukuthi iwuwoyela ovuzayo, kufanele ilungiswe noma ishintshwe ngokushesha ukuze kugwenywe ukulimala okwengeziwe enjinini.
05 Amafutha avuthayo
Ukuvuza kukawoyela kuphedi yekhava yegumbi le-valve kungase kubangele ukushiswa kukawoyela.Lapho iphedi yekhava yegumbi le-valve ivuza uwoyela, uwoyela ungangena egumbini elivuthayo lenjini bese ushisa negesi exutshwe.Lokhu ngeke kunciphise ukusebenza kahle kwenjini kuphela, kodwa kungase kubangele nokulimala kwenjini.Ngaphezu kwalokho, uwoyela ovuthayo nawo unyusa ukusetshenziswa kukaphethiloli futhi ungase ukhiqize isikhutha esiyingozi.Ngakho-ke, uma i-gasket yekhava yegumbi le-valve itholakala ukuthi ivuza uwoyela, kufanele ilungiswe kusenesikhathi ukugwema ukulimala okwengeziwe.
06 Ukwehliswa ngokushesha komthamo kawoyela
Ukuvuza kwephedi yekhava yegumbi le-valve kungabangela ukulahlekelwa ngokushesha kwamafutha.Lokhu kungenxa yokuthi ukuvuza kukawoyela kusho ukuthi uwoyela uyavuza ngaphakathi enjinini uya ngaphandle, ngaleyo ndlela kuncipha umthamo wamafutha ngaphakathi enjinini.Uma inani likawoyela linganele, ukuthambisa nokupholisa kwenjini kuzoncipha, okungaholela ekulimaleni kwenjini.Ngakho-ke, uma i-gasket yekhava yegumbi le-valve itholakala ukuthi ivuza uwoyela, i-gasket kufanele ishintshwe ngokushesha ngangokunokwenzeka ukuze kugwenywe ukuncishiswa okwengeziwe komthamo kawoyela.
07 Ukuvuvukala kwehhanisi nepayipi
Ukuvuza kwe-gasket yekhava yegumbi le-valve kungase kubangele ukuvuvukala kwehhanisi nepayipi.Lokhu kungenxa yokuthi ukuchitheka kukawoyela kuvame ukuhambisana nokuvuza kukawoyela eduze kwenjini, okungase kuhlangane namahhanisi namapayipi ezintambo.Amafutha anemiphumela yokugcoba kanye ne-insulating, kodwa uwoyela omningi ungabangela ukuthi ihhanisi nepayipi livuvuke.Ukuvuvukala kungathinta ukusebenza kwamahhanisi namapayipi ezintambo, futhi kungase kubangele ngisho nokujikeleza okufushane noma ukuphuka, okungathinta ukusebenza okuvamile kwemoto.Ngakho-ke, ukuvuza kwekhava ye-valve ekamelweni akuyona nje inkinga yemishini, kodwa futhi kungase kuhilele izinkinga ngesistimu kagesi.
08 ukwehlisa ingcindezi yesilinda namandla abuthakathaka
Ukuvuza kwephedi yekhava yegumbi le-valve kuzobangela umfutho we-cylinder wehle, okuzokwenza amandla emoto abe buthaka.Umsebenzi oyinhloko we-valve cover pad ukuvala igumbi le-valve nokuvimbela ukuvuza kwamafutha.Lapho i-gasket ivuza amafutha, amafutha azongena ekamelweni elivuthayo, okuholela ekunciphiseni isilinganiso sokucindezela ku-cylinder.I-Compression ratio iyinkomba ebalulekile yokukala ukusebenza kwenjini, uma incishisiwe, ukusebenza kahle kwenjini nakho kuzokwehla.Ngakho-ke, ukusebenza okuguquguqukayo kwemoto kuzothinteka, kuboniswe ukusheshisa kancane, ubunzima bokukhuphuka nezinye izinkinga.
09 Zinuke endaweni yenjini
Ukuvuza kwamafutha okuvela kukhava ye-valve casing kungabangela iphunga elibi endaweni yenjini.Lokhu kungenxa yokuthi ukuvuza kukawoyela kuvame ukuhambisana nokuvuza kukawoyela, futhi uwoyela ujwayele ukukhiqiza iphunga elibi endaweni yokushisa ephezulu yenjini.Iphunga alithinti nje kuphela ulwazi lokushayela, lingabonisa futhi inkinga yemishini emotweni.Uma leli phunga litholakala, kunconywa ukuthi uhlole injini ngokushesha ngangokunokwenzeka ukuze ugweme ukwehluleka okukhulu kwemishini.
Sicela usishayele uma udinga imikhiqizo enjalo.
