Izingxenye zokudluliswa kwesistimu yesikhathi zihlukaniswe zaba izinhlobo ezimbili: uchungechunge lwesikhathi nebhande lesikhathi, okuyizingxenye ezibalulekile zesitimela samavalvu enjini futhi zihlobene nesiphetho esiyinhloko senjini. Uma kunenkinga ebhandeni lesikhathi noma ochungechungeni lwezikhathi, lokho kuzodala ukungasebenzi kahle enjinini, futhi kudale nokuthi ichithwe yonke injini.
Abanikazi bezimoto abaningi bazi kuphela ukubaluleka kwazo zombili, kodwa abazi ukuthi yini umehluko phakathi kwe-timing chain ne-timing belt. Iluphi uhlobo lokudlulisela olungcono? Ingabe idinga ukushintshwa, futhi kangaki? Umhleli olandelayo uzokhuluma nawe.

1. Ibhande lesikhathi
Amabhande esikhathi ngokuvamile enziwa ngerabha, azoguga noma aguge ngokwanda kwesikhathi sokusebenza kwenjini. Ngakho-ke, ibhande lesikhathi kanye nezesekeli zalo ngokuvamile lidinga ukushintshwa ngemva kwesikhathi esithile senjini efakwe ibhande lesikhathi.
Kuzo zonke izinjini, ibhande lesikhathi alivunyelwe neze ukugxuma noma ukuphuka. Uma kwenzeka ukweqa izinyo, injini ngeke isebenze ngokujwayelekile, futhi kuzoba nokungenzi kahle okungazinzile, ukusheshisa okungekuhle noma ukungakwazi ukushaya imoto. Uma ibhande lesikhathi liphukile, injini izomisa ngokushesha, futhi injini ye-valve eminingi izophinde ibangele ama-piston. Ukugoba i-valve ephezulu kuzodala ukuthi injini ichitheke ngqo.
2. Uchungechunge lwezikhathi
Iketango lesikhathi ngokuvamile lenziwa ngezinto ezixubile. Igcotshwa ngamafutha aphilayo ngaphakathi enjinini. Impilo yesevisi ngokombono ingafinyelela ekugcineni kwezinsalela zemoto. Kodwa-ke, empeleni, i-chain tensioner nayo inempilo evamile yokugqoka. Sekusondele isikhathi sokuhlola nokufaka esikhundleni se-tensioner. Intengo yezingxenye ngokwemvelo incane kakhulu uma iqhathaniswa nekhithi yebhande lesikhathi.
3.Yikuphi okungcono, iketango lesikhathi noma ibhande lesikhathi?
Ibhande lesikhathi linobuhle bomsindo ophansi, ukumelana nokudlulisa okuphansi, amandla enjini amahle nokusebenza kokusheshisa, nokushintshwa okulula, kodwa kulula ukuguga, izinga lokuhluleka liphezulu uma kuqhathaniswa, futhi izindleko zokulilungisa ziphezulu.
Izinzuzo zochungechunge lwesikhathi ukuphila kwesevisi ende nezinga lokuhluleka eliphansi. Kunjalo, futhi inobubi bomsindo omkhulu ojikelezayo, ukusetshenziswa kukaphethiloli okuthe ukukhuphuka, kanye nokusebenza okuncishisiwe. Yiqiniso, ngokuthuthukiswa kobuchwepheshe, ukushiyeka kochungechunge lwezikhathi kuyathuthuka kancane kancane, futhi ngokusho kwentuthuko yamanje, uchungechunge lwesikhathi luzosetshenziswa kakhulu.
Kufanele kushintshwe kangaki uchungechunge lwesikhathi nebhande lesikhathi kushintshwe?

Izimoto ezisebenzisa amabhande esikhathi kufanele zishintshwe ngokuqinile ngokuhambisana nomjikelezo wokubuyisela. Ngokuvamile, kufanele zishintshwe lapho imoto isihambe amakhilomitha angu-60,000 kuya ku-100,000. Umjikelezo othize wokushintsha imoto kufanele usekelwe ebhukwini lokulungisa imoto.
Ngaphezu kwebhande, i-tensioner ne-idler kumele ishintshwe, kanti ezinye izimoto zibuye zibe namaphampu amanzi. Iphuzu liwukuthi izindleko zabasebenzi nazo ziphezulu. Uma ingashintshwa ngesikhathi, uma iphukile, izingxenye eziningi zizolimala. Amavalvu, ama-piston, izinduku zokuxhuma, njll. zingalimala, futhi izindleko zokuyilungisa zizoba phezulu.
Uchungechunge lwezikhathi alukhathazeki kakhulu. Izimoto eziningi ngeke zibe nankinga ngisho zingashintshwanga. Ngeke iphuke, futhi idinga ukushintshwa kuphela uma ihluleka. Umjikelezo omude wokushintsha kuyinzuzo enkulu yeketango, enganciphisa izindleko zomnikazi wemoto.
Kodwa futhi inobubi. Uma isibalo samakhilomitha senyuswa, iketango lizokwelulwa bese kuba nomsindo omkhulu kakhulu. Uma ufuna ukufaka esikhundleni seketango, izindleko ziphezulu kakhulu, futhi zibiza izinkulungwane ezimbalwa zamayuan ngesikhathi. I-chain tensioner yamanye amamodeli nayo izophuka, futhi iketango lizokwenza umsindo noma ngisho namazinyo eqe lapho ephukile. Uma amazinyo eseqiwe, isikhathi sidinga ukuhlelwa kabusha, futhi izindleko zabasebenzi ziphezulu. Ngakho-ke, uma iketango lingahluleki, alinakukhathazeka kakhulu. Uma ihluleka, izindleko zokuyilungisa ziba phezulu, kodwa imoto ye-timing chain ayivamisile ukwehluleka.

Amazwi okuphetha
Ngokuvamile, izinzuzo zamaketanga esikhathi ziphakeme kunamabhande esikhathi. Manje izimoto eziningi zisebenzisa amaketanga esikhathi, okusindisa ukukhathazeka futhi kunciphisa izindleko zezimoto kubanikazi bezimoto. Kodwa uma imoto yakho isebenzisa ibhande lesikhathi, ungakhohlwa ukulihlola nokulishintsha ngesikhathi!
