Ayini amabhande esikhathi namaketanga esikhathi futhi ahluke kanjani komunye nomunye? Hhayi-ke, impendulo elula ibhande elilodwa kanye neketango. Yiqiniso, lena akuyona impendulo ewusizo kakhulu. Futhi ufuna ukwazi kahle ukuthi benzani, ngakho-ke ake siqale ngenkulumo encane mayelana nesikhathi senjini, okuyisizathu sokuthi imoto yakho idinga ibhande noma iketango.

Okuyisisekelo kokusebenza kwesikhathi kwenjini

Izimoto eziningi namuhla zinenjini kaphethiloli enemivimbo emine. Lokhu kungenxa yokuthi inqubo yokusha ine-stroke ethathayo, i-compression stroke, i-stroke yamandla, kanye ne-exhaust stroke. Phakathi nomjikelezo wemivimbo emine, i-camshaft iphenduka kanye futhi i-crankshaft iphenduka kabili. Ubudlelwano phakathi kokujikeleza kwe-camshaft kanye ne-crankshaft bubizwa ngokuthi "isikhathi somshini". Yilokhu okulawula ukunyakaza kwamapiston namavalvu ngaphakathi kwamasilinda enjini yakho. Ama-valve adinga ukuvuleka ngesikhathi esiqondile kanye nama-piston, futhi uma engavuli, injini ngeke isebenze kahle, uma kwenzeka.

amabhande esikhathi

Maphakathi nawo-1960s, uPontiac wakha injini ye-inline-six okwakuyimoto yokuqala eyakhiwe eMelika ukuba ibe nebhande lesikhathi senjoloba. Phambilini, cishe zonke izinjini ezinemivimbo ezine zazifakwe uchungechunge lwesikhathi. Inzuzo yebhande ukuthi ithule kakhulu. Zihlala isikhathi eside, kodwa ziyaguga. Iningi labakhiqizi bezimoto batusa ukushintshwa kwebhande lesikhathi njalo ngamamayela angu-60,000-100,000. Njengoba usuwazi umsebenzi webhande lesikhathi, cishe asikho isidingo sokukutshela ukuthi awusoze waba nomphumela omuhle uma ugcina ngokugqashula ibhande lesikhathi.

Ibhande lesikhathi lihamba ochungechungeni lwama-pulley lapho kugxunyekwa khona izinsimbi zamabhande. Njengoba ungakwazi ukuqagela egameni, umsebenzi we-tensioner webhande ukugcina ibhande eliqinile ngaso sonke isikhathi. Ngokuvamile ziguga ngesikhathi esifanayo nebhande futhi zishintshwa kanye nokushintshwa kwebhande. Abakhiqizi abaningi kanye noomakhenikha nabo batusa ukuthi kushintshwe iphampu yamanzi. Lokhu kungenxa yokuthi iphampu yamanzi ivamise ukuba neminyaka efanayo futhi ivamise ukuguga ngesikhathi esifanayo.

Amaketanga esikhathi

Amaketanga esikhathi asebenza ngenjongo efanayo njengebhande, kodwa ngokuvamile ahlala isikhathi eside. Abanye abakhiqizi bathembisa ukuyishintsha ngezikhathi ezithile, abanye bathi izohlala isikhathi eside njengemoto uqobo.

Iketanga lesikhathi lifana neketango lebhayisikili futhi, njengoba ungalindela, linomsindo kunebhande. Enye inkinga ngamaketango ezikhathi ukuthi uma ephuka, ngokuvamile enza umonakalo omkhulu kunebhande eliphukile. Akukhona ukuthi sithi ibhande lesikhathi eliphukile ngeke likubangele izinkinga - lizokwenza njalo. Kodwa ngebhande eliphukile, umuntu angavele alungise amakhanda. Iketango eliphukile kungenzeka lidale umonakalo, okwenza ukwakhiwa kabusha kwenjini kushibhe kunokulungisa ozodinga.

I-timing chain nayo inama-tensioner ayibambayo, kodwa ngokungafani nama-tensioner amabhande, ama-timing chain tensioners alawulwa umfutho kawoyela wenjini. Ngakho-ke uma umfutho kawoyela wehla kakhulu nganoma yisiphi isizathu, ama-tensioners azohluleka, isikhathi sizoshintsha futhi iketango lizohluleka ngendlela emangalisayo. Amaketanga anenzuzo yokuthi awahlangene nepompo yamanzi, ngakho-ke ngokuvamile awudingi ukufaka esikhundleni sepompo ngesikhathi esifanayo ushintsha iketango.

Izinjini zokuphazamiseka

Ayikho ingxoxo yamabhande esikhathi namaketanga esikhathi engaqedwa ngaphandle kwamagama ambalwa mayelana nezinjini zokuphazamiseka. Enjinini yokuphazamiseka, ama-valve nama-piston ahlala endaweni efanayo kusilinda, kodwa hhayi ngesikhathi esifanayo. Lolu hlobo lwenjini olusebenza kahle kakhulu, kodwa uma unganakile ngokulungiswa kwayo, ungangena enkingeni. Uma ibhande lakho lesikhathi liphuka, amavalvu namapiston angagcina esesilinda ngesikhathi esifanayo. Cishe asikho isidingo sokukutshela ukuthi lokho kungaba kubi ngempela. Enjinini engaphazamisi, ibhande lingase linqamuke futhi lingabangeli monakalo wangaphakathi ngoba ama-piston nama-valve awakaze abe endaweni eyodwa.

Ngakho-ke, wazi kanjani ukuthi imoto yakho inenjini ephihliwe noma injini engaxutshwe nalutho? Cishe uzodinga ukuxhumana nomthengisi wakho noma umakhenikha.

Kwenzekani lapho ibhande lesikhathi noma iketango lilimele?

Ngokulungiswa okufanele, akunakwenzeka ukuthi uzoba nezinkinga ngebhande lesikhathi noma uchungechunge lwesikhathi. Kodwa uma lokhu kwenzeka, njengoba sesishilo kakade, awukho umphumela omuhle. Pho kwenzakalani ngempela?

Ibhande lesikhathi livamise ukuphuka uma uqala noma umisa injini. Lokhu kungenxa yokuthi kungalesi sikhathi lapho ukushuba kwebhande kusezingeni eliphezulu. Uma unenjini engenayo imfuhlumfuhlu, ngokuvamile ungakwazi ukuphuma ngokufaka ikhithi yebhande lesikhathi. Uma kuyinjini yokuphazamiseka, cishe kuzoba nomonakalo othile. Kungakanani kuzoncika ejubaneni lenjini ngesikhathi ibhande liphonswa. Uma lokhu kwenzeka ekuvaleleni noma ekuqaliseni, cishe uzogcina usunamavalvu agobile kanye/noma iziqondiso eziphukile zamavalvu. Kodwa-ke, uma iqala ukusebenza nge-RPM ephezulu, ama-valve cishe azophuka, agxume azungeze amasilinda, agobe izinti zokuxhuma futhi acekele phansi ipiston. Khona-ke, njengoba i-piston iphuka, izinduku zokuxhuma ziqala ukubhoboza izimbobo epanini likawoyela nesilinda, ekugcineni zihlukanise injini. Uma ucabanga ukuthi lokhu kuzwakala sengathi ukulungisa akunakwenzeka, uqinisile.

Manje mayelana neketango lesikhathi. Uma iketango ligqamuka ngesivinini esiphansi, lingase livele lishelele futhi lingalimazi. Uvele ufake ikhithi ye-timing chain futhi usuqedile. Uma iphuka noma iphuka nge-RPM ephezulu, izobhubhisa cishe yonke into ehlangana nayo. Ukulungisa kungase kwenzeke, kodwa kuzobiza.

Ukunakekela Okufanelekile

Ukunakekela kubalulekile. Uma umkhiqizi wemoto yakho encoma ukuthi ulishintshe ibhande noma iketango lakho njalo, kwenze lokho. Ukuyiyeka kuyingozi kakhulu futhi, kuye ngeminyaka yemoto yakho, kungase kuphumele ekuyilungiseni okubize ngaphezu kwenani langempela lemoto. Uma uthenge imoto esetshenzisiwe futhi ungaqiniseki ukuthi izingxenye zesikhathi zike zahlolwa yini, cela umakhenikha ahlole imoto.
