Izinyathelo zokuphepha zokushintsha isembozo segumbi lama-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 ingaphakathi lesembozo segumbi le-valve eligugile futhi lonakele: indawo ebomvu yesembozo segumbi le-valve esisusiwe yonakele futhi yawa, okuholele ekushiseni okukhulu kwamafutha. Bheka izembozo ezimbili ezintsha zegumbi le-valve 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 kuglue engakwesokunxele sengxenye yomkhiqizo kanye neglue engakwesokudla sesembozo segumbi le-valve yokuqala. Ngakho-ke uma ufuna ukushintsha, vele ushintshe izingxenye zokuqala.
Okwesithathu, ukushintshwa kwezinyathelo zokuphepha zesembozo segumbi le-valve le-1.6T Abagibeli abaningi bahlangabezane nokuvuza kwamafutha esembozo segumbi le-valve noma ukuguga kwe-valve embozweni wegumbi le-valve izinkinga zikawoyela ezishisayo. Ngemva kokuthi ukushintshwa kungazange kuxazulule inkinga, empeleni, yizizathu ezintathu, khumbula amaphuzu amathathu alandelayo, ukufaka 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 iphutha lokuklama.
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.
Ukuze sifingqe inkinga yokusha kwamafutha okubangelwa isembozo segumbi lama-valve sezimoto zomthetho, naka amaphuzu amabili: okokuqala, shintsha isembozo segumbi lama-valve sokuqala, bese kuthi okwesibili, thola izindawo zokuhlola zobungcweti, njengezitolo ezikhethekile zomthetho kanye nezitolo ze-Sunshine Artisans. Amafutha avuthayo abangelwa isembozo segumbi lama-valve angaba ngamalitha angu-4000 kuya kwangu-600, kungenzeka. Isigaba sokuqala asisibi kakhulu ukusetshenziswa kwelitha lamafutha ngamakhilomitha angu-4000, isigaba sakamuva sonakaliswe ngokuphelele ukusetshenziswa kwamafutha ngamakhilomitha ayi-1000 amakhulu.
