Izimpawu Zochungechunge Lwesikhathi Olunephutha noma Elinephutha

Izimpawu ezijwayelekile zeketango lesikhathi elibi zifaka ukungasebenzi kahle kwenjini, ukushefa kwensimbi emafutheni, nokugigigitheka kwenjini uma ingenzi lutho.

Selokhu kwavela injini yomlilo yangaphakathi, kusele eyodwa engashintshi - bonke banochungechunge lwesikhathi noma ibhande lesikhathi. Izinjini eziningi ezinkulu ezishintshayo zineketanga lesikhathi kunebhande lesikhathi. Iketango litholakala ngaphambili enjinini futhi lixhunywe kusethi yamagiya namapulley ashayela izinto eziningi zemishini, okuhlanganisa i-crankshaft necamshaft. Ukuze injini yakho iqale, uchungechunge lwezikhathi kufanele lujikeleze kahle emagiyeni ngaphandle kokungabaza. Nakuba iketango lesikhathi lenziwe ngensimbi, lingaphansi kokugqoka futhi lingaphuka uma lingashintshwa ngokuvumelana nezincomo zomenzi.

Uchungechunge lwezikhathi lwakhiwe uchungechunge lwezixhumanisi zamaketango afana nalawo atholakala ochungechungeni lwamabhayisikili. Izixhumanisi zigijima kuma-sprocket anamazinyo atholakala ekugcineni kwe-crankshaft ne-camshaft, anesibopho sokuvula nokuvala ama-valve ekhanda lesilinda namapiston anyakazayo kanye nezinduku zokuxhuma ekamelweni elivuthayo. Iketango lesikhathi linganwebeka futhi liguge ngokuhamba kwesikhathi, okuholela ekubambeni isikhathi kwenjini okungalungile nezimpawu eziningi eziyisixwayiso.

Uhlu olungezansi kunezimpawu ezi-5 zeketango lesikhathi eligugile. Uma ubona noma yiziphi zalezi zimpawu eziyisixwayiso, kuwumqondo omuhle ukuthinta umakhenikha wendawo ngokushesha ngangokunokwenzeka ukuze uthole imbangela yangempela futhi wenze ukulungisa okufanele uma kunesidingo.

1. Injini ayidubuli kahle noma ayisebenzi kahle

Kunezindlela ezimbili zokufinyelela isikhathi se-valve enjinini yangaphakathi evuthayo. Eyokuqala indlela enezigaba ezimbili, ehlanganisa ukuxhumana okuqondile kwe-crankshaft egiyeni le-camshaft. Le ndlela isetshenziswa ezinhlotsheni eziningi zemishini esindayo namaloli amakhulu. Indlela yokubala isikhathi ivame kakhulu ezimotweni zabathengi nasezinjinini ezisebenza kahle kakhulu. Ngokuhamba kwesikhathi, uchungechunge lwezikhathi lunganwebeka, okungabangela ukuthi igiya liphuthelwe kukhamera noma ku-crankshaft. Lokhu kubangela ukungahambi kahle kwesikhathi kwenjini futhi kuvame ukuholela ekushayweni kabi. Injini ingase ingasebenzi kahle futhi ingabi namandla okusheshisa.

Uma lesi simo senzeka, uchungechunge lwezikhathi luyolimala kakhulu futhi ludinga ukushintshwa ngokushesha ngangokunokwenzeka. Uma iketango lesikhathi liphuka, ukugingqika kwensimbi okuxekethile ngaphakathi kwenjini kungabangela ukulimala okukhulu kwenjini.

Bonke abakhiqizi bezimoto batusa ukushintsha uwoyela wenjini futhi bahlunge njalo ngamamayela ayi-3,000 kuya ku-5,000. Ngokuhamba kwesikhathi, amafutha aqala ukuhlukana njengoba eshisa futhi evezwa kumakhemikhali emvelo atholakala kuphethiloli. Uma iketango lesikhathi liqala ukuguga, izingcezu zensimbi ezincane zingagqashula iketango bese zingena epanini likawoyela. Lapho ushintsha uwoyela wakho futhi umakhenikha ekutshela ukuthi kwakukhona izingcezu zensimbi emafutheni akhanyisiwe noma okokuhlunga, lokho kuwuphawu oluhle lokuthi uchungechunge lwakho lwesikhathi luqala ukwehluleka.

Ama-metal chips nawo avame ukubonakala ngokuguga okunzima kuma-valve ekhanda le-cylinder, izibambi, ama-retainers nezinye izinsimbi zekhanda lesilinda. Kubalulekile ukuthi umakhenikha noma uchwepheshe ahlole inkinga futhi enze ukulungisa okufanele ngokushesha okukhulu.

3. Injini ayiqali noma ayisebenzi

Uchungechunge lwesikhathi oluvulekile luzobangela ukuthi injini ingaqali noma yehluleke ngenkathi ushayela. Uma ibhande selivele liphukile, injini ngeke ibe nokucindezelwa okwanele ukuze iqale. Uma iphuka noma ibhampa ngenkathi ushayela, ama-pistons azolimala ngokuthintana nama-valve. Ama-valve ngokwawo azogoba futhi akwazi ukucekela phansi injini. Uma ibhande lishibilika ngenxa yokuthi liyaxega, liyakwazi ukuxega futhi kulimaze nezinye izingxenye zenjini. Uma injini yakho ingaqali noma iqala ukusebenza kabi, okubonisa ukuthi kungenzeka ukuthi iyehluleka, yiba nesheke lokukhanda umakhenikha eliqinisekisiwe.

4. Hlola ukuthi ilambu lenjini livuliwe yini

Ukukhanya kwe-Check Engine kungakhanya ngezizathu ezahlukahlukene, esinye sazo esingaba ukwehluleka kweketango lesikhathi. Ikhompuyutha yemoto izobonisa izibani eziyisixwayiso okudingeka zihlolwe futhi ziskenwe amakhodi enkathazo ukuze kutholwe umthombo wenkinga. Isibani senjini yokuhlola singakhanya lapho ikhompuyutha esebhodini ithola okuthile okungalungile ngohlelo olukhipha umoya kanye nokusebenza kwenjini. Iketanga lesikhathi eleluliwe linomthelela ekwehliseni ukusebenza kwenjini kanye nokwanda kwekhabhoni ngokubangela ukukhanya kwenjini yokuhlola ukuthi kukhanye futhi kugcine i-DTC. Umakhenikha uzodinga ukuthi ahlole ikhodi futhi ahlele noma yikuphi ukulungiswa okudingekayo.

5. Injini iyakhenceza uma ingenzi lutho

Imisindo engajwayelekile futhi iyisixwayiso esivamile senkinga ngaphakathi kwenjini yakho. Ngaphansi kwezimo ezijwayelekile, injini kufanele yenze umsindo oshelelayo, onganyakazi okhombisa ukuthi konke kusebenza ngendlela efanele. Nokho, lapho uchungechunge lwezikhathi luxega, lungabangela ukundindizela ngaphakathi enjinini, okuzobangela umsindo okhencezayo lapho injini isamile. Ngaso sonke isikhathi uma uzwa umuntu engqongqoza, kusho ukuthi kukhona okuxegayo futhi okudinga ukulungiswa ngaphambi kokuba kuphuke.

Iketanga lesikhathi liyingxenye ebalulekile yanoma iyiphi injini, futhi ngaphandle kwalo, imoto yakho iba yize. Uma uchungechunge lwezikhathi luphuka ngenkathi ushayela, kungase kubangele ukulimala okukhulu kwenjini emotweni yakho. Indlela engcono kakhulu yokunciphisa amathuba okulimala okukhulu kwenjini iwukuba nomakhenikha ochwepheshile esikhundleni sochungechunge lwezikhathi uma ubona noma yiziphi izimpawu eziyisixwayiso ezibalwe ngenhla. Ngokukhuthala nangokuqapha, ungonga izinkulungwane zamadola futhi wandise kakhulu impilo yenjini yakho.
