Kusho ukuthini uma imoto yami "ishisa" uwoyela?
Ukushiswa kwamafutha kuvame ukubangelwa ukuvuza kwamafutha okuvutha enjinini eshisayo noma ezingxenyeni zesistimu yokukhipha umoya. Lungisa ukuvuza kukawoyela ukuze uvimbele ukulungiswa kwezimoto okumba eqolo.
Amafutha enjini kufanele abe ngaphakathi enjinini. Ngezikhathi ezithile, izimpawu zikawoyela noma ama-gaskets angavuza ngenxa yokuguga ngokweqile noma ukuchayeka emazingeni okushisa aphezulu. Ukuvuza kukawoyela kusabalalisa uwoyela ngaphandle kwenjini futhi ngokuvamile kwezinye izingxenye zenjini ezishisa kakhulu. Lokhu kukhipha iphunga lamafutha avuthayo. Kodwa-ke, akwaziwa ukuthi ukushiswa kukawoyela kungabangelwa ukulimala kwezingxenye zenjini yangaphakathi. Uma ukuvuza kungaxilongwa kahle noma kungalungiswa, noma inkinga yangaphakathi yenjini ingaxazululeki, uwoyela owengeziwe uzovuza noma udle, okungase kudala isimo esiyingozi.
Kunezinto ezimbalwa okufanele uziqaphele ezizokusiza ukuthi ubone ukuvuza kukawoyela nokuthi yini okufanele uyenze ukuze ulungise inkinga ngaphambi kokuba idale umonakalo omkhulu wenjini noma isimo esiyingozi.
Ungazi kanjani ukuthi imoto yakho ishisa amafutha
Njengoba kuphawuliwe ngenhla, ukushiswa kukawoyela kungabangelwa ukuvuza kwamafutha noma ukulimala kwezingxenye zenjini yangaphakathi. Awufuni ukulinda kuze kube yilapho izinga likawoyela lehla kakhulu ukuze wazi ukuthi unenkinga, ngakho ukuze ulungise le nkinga, kufanele uqonde ukuthi ungabona kanjani ukuthi imoto yakho ishisa amafutha. Nazi izimpawu ezimbalwa ozozibona:
Uma unowoyela ovuzayo futhi uwoyela ovuzayo ushaya i-exhaust noma ezinye izinto ezishisayo, ngokuvamile ungahogela uwoyela ovuthayo ngaphambi kokuba ubone intuthu.
Ungase futhi ubone intuthu eluhlaza okotshani lapho injini isebenza. Uma ubona lokhu ngenkathi usheshisa, kungenzeka ukuthi izindandatho zakho ze-piston zonakele. Uma umusi uphuma ngesikhathi sokunciphisa, inkinga ngokuvamile ibangelwa iziqondiso ze-valve ezilimele emakhanda e-cylinder.
Yini eyenza amafutha ashise
Isizathu sokushisa uwoyela ukuthi uvuza lapho kufanele ube khona futhi usezicini ezishisayo ezifana ne-exhaust manifolds, amakhava amavalvu, noma ezinye izinhlelo zenjini. Njengoba imoto iguga, izingxenye ezihlukahlukene zingase ziguge futhi zehluleke ukuvaleka kahle ngowoyela. Amafutha ayaphuma athinte izingxenye zenjini eshisayo.
Njengoba kushiwo ngenhla, iphunga lamafutha ashisiwe lingabuye liphume epayipini lokukhipha umoya. Uma izindandatho ze-piston zonakalisiwe, ukushiswa kwamafutha kubangelwa ukuntuleka kokucindezela ekamelweni elivuthayo kanye namafutha amaningi angena ekamelweni elivuthayo. Lokhu futhi kuyimbangela yokushiswa kwamafutha uma iziqondiso ze-cylinder head valve zilimele.
Uma i-valve ye-crankcase ventilation (PCV) enhle igqokwa, iphinde ivumele uwoyela ukuthi ungene egumbini elivuthayo. I-valve ye-PCV engalungile noma egugile ivumela ingcindezi ukuba yakheke, ekhipha ama-gaskets aklanyelwe ukuvala uwoyela. I-valve esebenza kahle ikhipha amagesi ku-crankcase ukuvimbela ukunqwabelana kwengcindezi.
Ukushisa uwoyela kungaholela ezinkingeni ezinkulu, ezihlanganisa ukuhluleka kwenjini. Uma ubona inkinga ngemoto yakho, yihlole ngokushesha ngaphambi kokuba inkinga ibe yimbi kakhulu.
