Yenza ngokwakho esikhundleni se-piston izindandatho ku-VAZ 2107
Izinjini ze-VAZ 2107, kuhlanganise nazo zonke ezinye izinhlobo "zakudala", ziyakwazi ukugijima kuze kufike ku-300 km ngaphandle kokulungiswa okukhulu. Yiqiniso, akuwona wonke umnikazi okwazi ukuqapha imoto yakhe ngendlela yokufeza imiphumela enjalo, kodwa kufanelekile ukulwela lokhu.
Kodwa ngokuvamile abantu abaningi balungisa izinjini zabo kusenesikhathi. Lokhu kungenxa yokugqoka ngaphambi kwesikhathi kweqembu le-piston: izindonga zesilinda, izindandatho zepiston, kokubili i-oil scraper kanye namasongo okucindezela. Ukucindezela kulesi simo ngokuvamile kwehla kakhulu futhi kuwela ngaphansi kwe-atmospheres engu-10, yiqiniso, kuyadingeka ukulungisa injini. Leli bhukwana lizokuhamba ngenqubo yokushintsha izindandatho zepiston. Kodwa okokuqala udinga ukwenza izinyathelo zokulungiselela:
- Susa ku-cylinder head block
- Ukukhipha ithreyi lenjini
[colorbl style=”green-bl”]Khumbula ukuthi ukuze kube lula, lokhu kulungiswa kwe-VAZ 2107 kwenziwa emgodini. Kodwa uma uyilungisa ngokuphelele injini yomlilo yangaphakathi, ungakwazi ngisho nokukhipha injini ngaphansi kwesivalo.[/colorbl]
Lapho zonke izinyathelo zokulungiselela seziqediwe, ungaqala ukusebenza. Okokuqala, sikhulula amantongomane amabili avikela izigqoko zenduku yokuxhuma, futhi ngenxa yalokhu sidinga i-knob enekhanda le-14. Njengoba amantongomane efakwe nge-torque enkulu, kungase kudingeke ukwakha i-lever nge ipayipi.
Manje ungakwazi ukususa kalula ikhava bese uyibeka eceleni. Kodwa khumbula ukuthi ngesikhathi sokufakwa udinga ukubeka yonke into endaweni yayo, okungukuthi, ungaphambanisi izembozo zama-piston ahlukene!
Uma lokhu sekwenziwe, ungazama ukukhama i-piston ngaphandle ngokucindezela amabhawodi enduku yokuxhuma. Kodwa bheka ukuthi akukho ukuhlanekezela, okungukuthi, ukuthi induku yokuxhuma isesimweni esiqondile. Kungase kudingeke ukuthi uvule i-crankshaft kancane nge-pulley yayo ukwenza lokhu.
Ngokwami, ngesibonelo sami, ngingasho ukuthi kulula kakhulu ukukhama i-piston ngosizo lwebhulokhi yokhuni, ukuyibeka ngokumelene ne-bolt yenduku yokuxhuma. Ngemuva kwalokho, kufanele iphume kalula futhi iyikhiphe ngesandla kuze kube sekupheleni, njengoba kuboniswe esithombeni esingezansi:
Sisebenza ngokuqapha okukhulu, ekugcineni sisusa umhlangano wepiston ezindongeni zokuxhuma ngaphandle:
Okulandelayo, siqhubekela ngqo ekushintsheni izindandatho, uma kunesidingo. Ukuze wenze lokhu, vula kancane unqenqema lwendandatho yokucindezela ephezulu bese uyikhipha ekuhlanganyeleni kwe-groove, njengoba kukhonjisiwe ngezansi:
Ukuze uyikhulule ngokuphelele indandatho, kufanelekile ukuyikhipha ngokucophelela emseleni kumbuthano:
Amanye amasongo asuswa ngendlela efanayo. I-oil scraper ephansi kakhulu ingase igoqeke, ngakho khumbula lokhu. Okulandelayo, udinga ukukala igebe phakathi kwamaphethelo endandatho ngokuyifaka kusilinda:
Kuvunywa ngokujwayelekile ukuthi ubukhulu obuvunyelwe, okungukuthi, igebe elibucayi, akufanele libe ngaphezu kwe-1 mm. Futhi igebe elilungile lokusebenza ngu-0,25-0,45 mm. Uma, ngemva kokulinganisa, kwavela ukuthi amanani awavunyelwe ukusetshenziswa, izindandatho kufanele zishintshwe ngokushesha.
Ngaphambi kokufaka ama-pistons, ama-grooves ayo kufanele ahlanzwe ngokuphelele kumadiphozi ekhabhoni. Kungcono ukwenza lokhu ngendandatho endala, ilingana kahle nalokhu. Khona-ke ungakwazi ukufaka izindandatho ezintsha endaweni. Futhi uma ubuyisela ipiston kusilinda, qiniseka ukuthi ugcoba yonke into ngamafutha enjini, ungawugodli.
Amanani amasongo amahle ahlanganisa ngaphezu kwe-50 km angabiza okungenani ama-ruble angu-000. Kubalulekile ukuthi ngemva kokuhlanganisa injini ye-VAZ 1000, kuyadingeka ukuyiqhuba, okungenani i-2107 km yokuqala ukuze iqhube imoto ngemodi emnene.
