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 ikhava yevalvu evundlile, maningi amathuba okuthi ingasebenzi kahle, futhi maningi ayingozi kwezokuphepha, njengokuthi injini ingasebenzi ihora lonke, ikhava yevalvu ayivuzi, injini igibela umqansa. , futhi i-accelerator icindezelwe, lapho ukucindezela okungalungile kukhulu, amafutha azophuma ku-valve cover pad. 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, isembozo se-aluminium ingxubevange akuyona imboni yokuqala ayilungile ukuyisebenzisa, ngoba uma i-valve ifakiwe, ipulasitiki iqinile, i-aluminium alloy ayiyona into encane, kanye nesimo sokuvuza kwamafutha. kuzokwenzeka isikhathi eside. 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, ngemuva kokuvula ikhava yegumbi le-valve, isikhathi sokupholisa kufanele sanele, iphuzu lesithathu, ngokusho kwe-torque evamile, ukuze kufakwe izikulufa, inqobo nje uma amaphuzu amathathu angenhla, angaba yisixazululo esihle inkinga, inkinga yekhava yegumbi le-valve ayilona 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, ngemuva kwemoto eshisayo, ukuthola inani elibi lokucindezela, faka umkhawulo owodwa wepayipi echwebeni lokugcwalisa le-gauge yamafutha, bese usetha omunye umkhawulo njengeyunithi ye-mbar, ungaqala ukuhlola. I-1.6T inani elijwayelekile elizungeze i-35 kukhona ushintsho oluncane, uma ngaphansi kuka-25 ngokusobala kuzoqala ukudla amafutha, ngalesi sikhathi ukusetshenziswa kwezindlela zendabuko zokuvula i-cap yamafutha khipha i-gauge yamafutha ayibonwa, cishe ingaba seduze 3000-4000 amakhilomitha ilitha ukusetshenziswa uwoyela. 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.
