I-Tensioner - Idivayisi yokulungisa i-tensioner yebhande lesikhathi kanye neketanga lesikhathi.
Isenzo se-tensioner.
Ngaphansi kokudluliselwa kwebhande lesikhathi noma uchungechunge lwesikhathi, i-camshaft iqhuba i-valve ukuthi ivuleke futhi ivale ngesikhathi esifanele, futhi iqedele izinqubo ezine zokungenisa, ukucindezela, ukusebenza kanye nokukhipha umoya nge-piston. Ngoba ibhande lesikhathi kanye nochungechunge lwesikhathi kuzogxuma lapho kusebenza ngesivinini esiphakathi nesiphezulu, futhi ibhande lesikhathi lizokhula futhi liguquguquke ngenxa yezinto ezibonakalayo namandla ebhande ekusetshenzisweni kwesikhathi eside, okuholela ekuthini isikhathi se-valve singanembile, okuholela ezindleleni zikaphethiloli zemoto, ubuthakathaka, ukungqongqoza kanye nokunye ukwehluleka. Uma amazinyo amaningi eqa ngoba i-valve ivuleke kusenesikhathi noma ivaliwe sekwephuzile kuzobangela umonakalo wokushayisana kwe-valve kanye ne-piston ephezulu enjinini.
Ukuze ibhande lesikhathi kanye neketanga lesikhathi kugcine izinga lokuqinisa elifanele, okungukuthi, hhayi ngenxa yamazinyo axegayo kakhulu futhi hhayi ngenxa yomonakalo oqinile kakhulu, kunesistimu ekhethekile yokuqinisa, equkethe i-tensioner kanye nesondo lokuqinisa noma i-guide rail. I-tensioner inikeza ingcindezi ebheke ebhandeni noma ku-chain, i-tensioner ixhumana ngqo nebhande lesikhathi, kanti i-guide rail ixhumana ngqo neketanga lesikhathi, futhi basebenzisa ingcindezi enikezwa yi-tensioner kuyo ngenkathi isebenza nebhande noma iketanga, ukuze balondoloze izinga elifanele le-tensioner.
Yiluphi uphawu oluzophulwa yi-tensioner yejeneretha yemoto
I-tensioner yejeneretha yemoto ephukile izoholela ekusetshenzisweni kukaphethiloli okwandisiwe, ukuntuleka kwamandla, ukungqongqoza, umsindo ongavamile wenjini kanye nezinye izimpawu.
I-tensioner iqondisa futhi iqinise ibhande lesikhathi noma uchungechunge lwesikhathi lwenjini, iqinisekisa ukuthi lezi zingxenye zihlala zisesimweni esihle kakhulu sokuqinisa. Uma i-tensioner yonakele, izokwenza ukuthi ibhande lesikhathi noma uchungechunge lukhululeke, okuzoholela ochungechungeni lwezinkinga. Okokuqala, ukusetshenziswa kukaphethiloli kuzokwanda ngoba uhlelo lwesikhathi ngeke lusebenze kahle, okuholela ekunciphiseni ukusebenza kahle kohlelo lwe-valve yenjini. Okwesibili, ukuntuleka kwamandla kungenxa yokuthi i-valve ne-piston kuyasebenzisana nenkinga, okuholela ekutheni amandla aphelele emoto abe buthaka. Ngaphezu kwalokho, kungenzeka futhi kube nomcimbi wokungqongqoza, okubangelwa ukuhlanganiswa okungafanele kwe-valve ne-piston ngesikhathi sokunyakaza. Okokugcina, umsindo wenjini ongajwayelekile uwuphawu olusobala, ngoba ukuxega kwebhande lesikhathi noma uchungechunge kuzobangela umsindo ongajwayelekile ngesikhathi sokusebenza.
Uma i-tensioner yonakele futhi ingashintshwa ngesikhathi, ingabangela izinkinga ezinkulu kakhulu. Injini ingase ixegezele, ibe nobunzima bokuvutha, noma yehluleke ukuqala ezimweni ezimbi kakhulu. Ngaphezu kwalokho, i-valve ingase ikhubazeke, okuholela ekulimaleni kwezingxenye zenjini. Uma i-tensioner yehluleka ngokuphelele, ingabangela ibhande ukuba lihluleke ukushayela kahle futhi ekugcineni ibangele ukuba imoto iphuke.
Ingabe umsindo ongavamile wesondo lokucindezela uyalimaza imoto?
Umsindo ongajwayelekile wesondo lokuqinisa uzolimaza imoto, futhi uma ungashintshwa ngesikhathi, uzoholela ezinkingeni zokuphepha kokushayela, njengokujikijela kwenjini, ubunzima bokusha, ngisho nokungakwazi ukushaya imoto. Lesi simo singase senzeke lapho isondo lokuqinisa linomsindo ongajwayelekile, ngakho-ke kuyadingeka ukufaka esikhundleni isondo lokuqinisa ngesikhathi. Uma kungaphathwa ngesikhathi, umsindo ongajwayelekile wesondo lokuqinisa ungaba nemiphumela emibi emotweni, njengokuguqulwa kwevalvu.
Isondo lokuqinisa liyingxenye ebalulekile yenjini, elawula ukuqina kwebhande lenjini ngokuxhuma injini kanye nebhokisi legiya ukuqinisekisa ukusebenza okuvamile kwenjini. Uma kunenkinga ngesondo lokuqinisa, injini inganyakaza, ubunzima bokusha kanye nezinye izimo, okuzothinta ukuphepha kokushayela. Ngakho-ke, kunconywa ukuthi kushintshwe isondo lokuqinisa ngesikhathi lapho kunomsindo ongajwayelekile ukuqinisekisa ukusebenza okuvamile kwemoto.
Umsindo ongajwayelekile wesondo lokucindezela ungabangela ukushukuma kwenjini, ngoba injini izothinteka yisondo lokucindezela ngesikhathi sokusebenza, okuholela ekusebenzeni okungazinzile. Ngaphezu kwalokho, umsindo ongajwayelekile wesondo lokuqinisa ungabangela nobunzima bokusha, okwenza imoto ingakwazi ukuqala ngendlela evamile. Uma kunenkinga ngesondo lokuqinisa, kungase kungenzeki ngisho nokushaya imoto. Ngakho-ke, umnikazi kufanele anake isimo sesondo lokuqinisa futhi alishintshe ngesikhathi.
Umthelela womsindo ongajwayelekile wesondo lokuqinisa emotweni awunakunakwa, uma ungashintshwa ngesikhathi, ungaholela ezinkingeni ezinkulu njengokuguqulwa kwevalvu. Umnikazi kufanele ahlole isimo sesondo lokucindezela njalo ukuqinisekisa ukusebenza okuvamile kwenjini. Uma kunomsindo ongajwayelekile, isondo lokukhulisa kufanele lishintshwa ngokushesha ukuze kugwenywe umonakalo owengeziwe enjinini. Ngamafuphi, umsindo ongajwayelekile wesondo lokuqinisa uzolimaza imoto futhi udinga ukuxazululwa ngesikhathi.
