Iyini imiphumela yephedi yokumboza igumbi le-valve elivuzayo?
Izinyathelo zokuphepha zokushintsha isembozo segumbi le-valve:
Okokuqala, qiniseka ukuthi usebenzisa isembozo segumbi le-valve sokuqala
Ukufaka isembozo segumbi le-valve lokuqala kuzoxazulula inkinga. Igumbi le-valve lokuqala le-Peugeot Citroen lenziwe yi-Mega, futhi lena yinombolo yalo. Kunezimpahla eziningi ezifanayo emakethe, futhi ikhwalithi engu-95% imanzi kakhulu, uma ungenayo isiteshi esithembekile sokuthenga, amathuba okuthenga isembozo segumbi le-valve elifanayo aphezulu njengo-95%. Uma usuthole isembozo se-valve esivundlile, kunethuba elikhulu lokuthi akukuhle ukusisebenzisa, futhi kunezingozi eziningi zokuphepha, njengokuthi injini ayisebenzi ihora lonke, isembozo se-valve asivuzi, injini ikhuphuka endaweni ethe shí, bese i-accelerator icindezelwa, lapho ingcindezi engemihle inkulu, uwoyela uzophuma ephepheni lesembozo se-valve. Uma uwoyela wenjini ekhabini unzima kakhulu, ugeleza uye ku-exhaust manifold engezansi, futhi kulula ukubangela umlilo wenjini ngaphansi kokushisa okuphezulu okungaphezu kwama-degrees angu-400 ku-exhaust manifold, futhi izingozi zokuphepha ezingaba khona zinkulu. Abanye abantu bashintsha isembozo se-aluminium alloy, isembozo se-aluminium alloy akuyona ifektri yokuqala asilungele ukusetshenziswa, ngoba uma i-valve ifakiwe, ipulasitiki iyaqina, i-aluminium alloy ayinciphisi kakhulu, futhi isimo sokuvuza kwamafutha sizokwenzeka isikhathi esithile. Vele, ifektri yokuqala iyi-aluminium alloy, kumele sishintshe isembozo se-aluminium alloy yokuqala, ifektri yokuqala iyipulasitiki, kumele sishintshe isembozo sepulasitiki sokuqala.
Okwesibili, indlela yokubona isembozo segumbi le-valve yokuqala
Kunzima kakhulu ukuhlukanisa ngokubheka isembozo segumbi le-valve kuphela. Okokuqala, bheka isimo sangaphakathi sesembozo segumbi le-valve esigugile futhi sonakele: indawo ebomvu yesembozo segumbi le-valve esisusiwe yonakele futhi yawa, okuholele ekushisweni okukhulu kwamafutha. Bheka izembozo zegumbi le-valve ezimbili ezintsha ukuthi ungahlukanisa kanjani phakathi kokuhle nokubi, indlela elula yokuqhathanisa iglue emithungweni, iglue ezingxenyeni zomkhiqizo, kanye nemithungo efektri yokuqala iMeijia. Imithungo yeglue yezingxenye zomkhiqizo ilukhuni, ibonakala ngamehlo enyama, futhi iglue yezingxenye zokuqala iyafana kakhulu futhi icocekile. Iglue esesivalweni ngaphansi kwesivalo samafutha nayo ihluke kakhulu kuneglue engakwesokunxele sengxenye yomkhiqizo kanye neglue engakwesokudla sesembozo segumbi le-valve yokuqala. Ngakho-ke uma ufuna ukushintsha, vele ushintshe izingxenye zokuqala. Okwesithathu, ukushintshwa kwezinyathelo zokuqapha zesembozo segumbi le-valve esingu-1.6T Abagibeli abaningi baye bahlangabezana nokuvuza kwamafutha esembozweni segumbi le-valve noma ukuguga kwezinkinga zamafutha asembozweni segumbi le-valve. Ngemva kokuba ukushintshwa kungazange kuxazulule inkinga, empeleni, yizizathu ezintathu, khumbula amaphuzu amathathu alandelayo, ukufaka esikhundleni isembozo segumbi le-valve akuvimbi. Okokuqala, isembozo segumbi le-valve sokuqala, okuyisici esibalulekile; Iphuzu lesibili, ngemva kokuvula isembozo segumbi le-valve, isikhathi sokupholisa kufanele sanele, iphuzu lesithathu, ngokusho kwe-torque ejwayelekile, ukuze kufakwe izikulufo, inqobo nje uma amaphuzu amathathu angenhla, angaba yisisombululo esihle senkinga, inkinga yesembozo segumbi le-valve akuyona inkinga yokuklama.
Okwesine, sinaka kakhulu inani lokucindezela elibi
Ukucindezela okungekuhle kwenjini engu-1.6T akujwayelekile kubantu abaningi, futhi sizokunikeza leli nani namuhla ukuze kube lula ukuhlola ukusha kukawoyela esikhathini esizayo. Okokuqala, kukhona ithuluzi lokuhlola inani lokucindezela okungekuhle, ngemva kwemoto eshisayo, ukuthola inani lokucindezela okungekuhle, ukufaka umkhawulo owodwa wepayipi echwebeni lokugcwalisa legeji kawoyela, bese usetha olunye uhlangothi njengeyunithi ye-mbar, ungaqala ukuhlola. Inani elijwayelekile elingu-1.6T cishe ku-35 kukhona ushintsho oluncane, uma ngaphansi kuka-25 kuzoqala ngokusobala ukudla uwoyela, ngalesi sikhathi ukusetshenziswa kwezindlela zendabuko zokuvula isivalo sikawoyela ukukhipha igeji kawoyela akubonwa, cishe kungaba cishe amakhilomitha angu-3000-4000 ilitha lokusetshenziswa kukawoyela. Uma kungaphansi kuka-12, kuzoba nokusetshenziswa kukawoyela okungavamile okusobala, futhi ukusetshenziswa kwelitha likawoyela amakhilomitha angamakhulu amaningana 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.
