Uyini umphumela wephedi yekhava ye-valve yegumbi elivuzayo?
Izinyathelo zokuphepha zokushintshwa kwekhava ye-valve:
Okokuqala, qiniseka ukuthi usebenzisa isembozo sokuqala segumbi le-valve
Ukushintsha ikhava yokuqala yegumbi le-valve kuzoxazulula inkinga. Igumbi lokuqala le-valve ye-Peugeot Citroen lenziwe yi-Mega, futhi lena ingxenye yenombolo yayo. Kunezimpahla eziningi ezifanayo emakethe, futhi ikhwalithi engu-95% ingamanzi kakhulu, uma ungenakho ukuthengwa kwesiteshi okuthembekile, amathuba okuthenga ikhava yegumbi le-valve elihambisanayo afinyelela ku-95%. Uma usuthole isembozo sevalvu evundlile, maningi amathuba okuthi akulungile ukusisebenzisa, futhi ziningi izinto eziyingozi zokuphepha, njengokuthi injini ibambe ihora lonke, ikhava yevalvu ayivuzi, injini igibela umqansa, i-accelerator iyacindezelwa, uma i-negative pressure inkulu, uwoyela uzovuza ku-pad ye-valve. Uma uwoyela wenjini ekhabetheni unzima kakhulu, ugeleza ufika exhaust eningi ngezansi, futhi kulula ukubangela umlilo wenjini ngaphansi kwezinga lokushisa eliphakeme elingaphezu kwama-degree angu-400 endaweni yokukhipha umoya, futhi izingozi ezingase zibe khona zokuphepha zinkulu. Abanye abantu bashintsha ikhava ye-aluminium alloy, ikhava ye-aluminium alloy akuyona ifektri yokuqala ayilungile ukuyisebenzisa, ngoba uma i-valve ifakiwe, ipulasitiki ishubile, i-aluminium alloy ayinamandla amancane, futhi isenzakalo sokuvuza kwamafutha kuzokwenzeka isikhathi esithile. Yiqiniso, imboni yokuqala iyingxubevange ye-aluminium, kufanele siguqule isivalo sokuqala se-aluminium ingxubevange, imboni yokuqala iyipulasitiki, kufanele sishintshe isivalo sokuqala sepulasitiki.
Okwesibili, indlela yokuhlonza isembozo sokuqala segumbi le-valve
Kunzima kakhulu ukuhlukanisa kuphela ngokubheka ikhava yegumbi le-valve. Okokuqala, bheka isimo sangaphakathi sesembozo segumbi le-valve esigugile futhi sonakaliswa: indawo ebomvu yekhava yegumbi le-valve elisusiwe lonakele futhi lawa, okuholele ekushisweni kukawoyela okubi kakhulu. Bheka amakamelo amabili ama-valve amasha amboza indlela yokuhlukanisa phakathi kokuhle nokubi, indlela elula yokuqhathanisa iglu emithungweni, ingcina ezingxenyeni zomkhiqizo, kanye nemithungo efektri yokuqala i-Meijia. I-glue seams yezingxenye zomkhiqizo zinzima, zibonakala ngeso lenyama, futhi i-glue yezingxenye zangempela ifana kakhulu futhi ihlanzekile. I-glue ocingweni ngaphansi kwesivalo samafutha nayo ihluke kakhulu ku-glue kwesokunxele sengxenye yomkhiqizo kanye ne-glue kwesokudla sekhava yegumbi le-valve yasekuqaleni. Ngakho uma ufuna ukushintsha, vele ushintshe izingxenye zangempela. Okwesithathu, ukushintshwa kwezinyathelo zokuphepha zekhava yegumbi le-valve engu-1.6T Abagibeli abaningi bahlangabezane nekhava yegumbi le-valve ukuvuza kwamafutha noma ukuguga kwe-valve egumbini le-valve lekhava yegumbi lezinkinga ze-oyela ezivuthayo. Ngemva esikhundleni akazange ukuxazulula inkinga, eqinisweni, kuba izizathu ezintathu, khumbula amaphuzu amathathu alandelayo, esikhundleni ikhava valve ekamelweni akusho detente. Okokuqala, isembozo sokuqala segumbi le-valve, okuyisici esibalulekile; Iphuzu lesibili, ngemva kokuvula ikhava yegumbi le-valve, isikhathi sokupholisa kufanele sanele, iphuzu lesithathu, ngokusho kwe-torque evamile, ukuze kufakwe izikulufa, inqobo nje uma amaphuzu amathathu angenhla, kungaba yisixazululo esihle senkinga, inkinga yekhava yegumbi le-valve ayiyona iphutha lokuklama.
Okwesine, sinaka kakhulu inani lokucindezela elibi
Ingcindezi engeyinhle yenjini engu-1.6T ayijwayelekile kubantu abaningi, futhi sizokunikeza leli nani namuhla ukuze kube lula ukuhlolwa kokushiswa kukawoyela esikhathini esizayo. Okokuqala, kukhona ithuluzi lokuhlola inani elibi lokucindezela, emva kwemoto eshisayo, thola inani elibi lokucindezela, faka umkhawulo owodwa we-hose echwebeni lokugcwalisa le-gauge yamafutha, bese ubeka omunye umkhawulo njengeyunithi ye-mbar, ungaqala ukuhlola. I-1.6T inani elivamile elizungeze i-35 kukhona ushintsho oluncane, uma ngaphansi kwe-25 ngokusobala izoqala ukudla amafutha, ngalesi sikhathi ukusetshenziswa kwezindlela zendabuko zokuvula i-cap yamafutha ikhiphe i-gauge yamafutha ayibonwa, cishe ingaba eduze namakhilomitha angu-3000-4000 ilitha lokusetshenziswa kwamafutha. Uma ingaphansi kuka-12, kuzoba nokusetshenziswa kukawoyela okusobala okungavamile, futhi ukusetshenziswa kwelitha lamafutha amakhilomitha angamakhulu ambalwa noma amakhilomitha ayinkulungwane kuyinto evamile. Ikakhulukazi lapho isembozo sokuqala segumbi le-valve siguga, ukusetshenziswa kukawoyela ekushayeleni ngesivinini esiphansi edolobheni akubonakali, futhi ukusetshenziswa kukawoyela ekushayeleni ngesivinini esikhulu kuzoba sobala.
