Isihlungi samafutha
Isihlungi sikaphethiloli ezimotweni siyingxenye ebalulekile yesistimu kaphethiloli ehlunga izinhlayiya ezincane zokugqwala nothuli, futhi futhi livimbele ukuthi lingangeni emgqeni wesistimu kaphethiloli. Uma kungabikho isihlungi kanye nendawo encane yokugeleza emgqeni kaphethiloli, izinhlayiya zothuli nokugqwala zivala uhlelo, zivimbela ukunikezwa kwamafutha enjini.
Isistimu yokuhlunga ihlukaniswe izigaba ezimbili zokuhlunga. Isigaba esiyinhloko nesokuqala sokuhlanza uphethiloli ukuhlanza okuqinile, okususa izinhlayiya ezinkulu zokungcola kuphethiloli. Isigaba sesibili sokuhlanza ukuhlanza uphethiloli omuhle, lesi sihlungi esifakwe phakathi kwe-tank fuel kanye nenjini ikuvumela ukuba ususe izinhlayiya ezincane zokungcola.
Izinhlobo nezigaba zezihlungi
Kuye ngesistimu kaphethiloli, isihlungi esihle sikhethwa ngenxa yezizathu zokuthi isihlungi ngasinye sesistimu ngayinye yamafutha sihlukile ekuklanyweni.
Ngakho-ke, sinezinhlobo ezintathu zokuhlunga ngokuya ngesistimu yokunikezela uphethiloli:
- I-Carburetor;
- Umjovo;
- Udizili.
Izihlungi nazo zihlukaniswe ngezigaba ezimbili: eziyinhloko (zitholakala kulayini kaphethiloli ngokwawo (isibonelo: igridi ethangini), kanye ne-submersible - zifakwe ethangini kanye nepompo.
Isihlungi sikaphethiloli esimahhadla siyisihlungi se-mesh, kanye nesibonisi, i-mesh iqukethe ithusi futhi ayivumeli izinhlayiya ezinkulu kuno-0,1 mm ukuthi zingene. Ngakho, lesi sihlungi sisusa ukungcola okukhulu kuphethiloli. Futhi isici sokuhlunga ngokwaso sitholakala engilazini, exhunywe ngendandatho encane kanye nama-bolts. I-paronite gasket ivala igebe phakathi kwengilazi nomzimba. Futhi ngaphansi kwengilazi kune-pacifier ekhethekile.
Ngakho, isihlungi siyahlanza ngaphambi kokuba uphethiloli ungene ohlelweni lukaphethiloli. Futhi, isihlungi sikaphethiloli sisebenzisa i-valve yokunciphisa umjovo, elawula ingcindezi yokusebenza ohlelweni lukaphethiloli, konke lokhu kufakwa ngaphezu kwesistimu yomjovo oqondile. Futhi uphethiloli oweqile ungaphindiselwa emuva ethangini likaphethiloli. Kuhlelo lukadizili, isihlungi sisetshenziswa ngendlela efanayo, kodwa sinomklamo ohlukile.
Uma isihlungi sikaphethiloli sizoshintshwa nguwe, okokuqala udinga ukunquma indawo yesihlungi. Ngokuzenzakalelayo kuzoba:
- Ngaphansi kwephansi lemoto;
- Ethangini likaphethiloli (i-mesh ethangini);
- Igumbi lenjini.
Isihlungi sikaphethiloli singashintshwa kalula ngaphandle kosizo lochwepheshe, kodwa uma ungabaza amakhono akho, ungacela iseluleko kubashayeli abanolwazi olunzulu noma ubuze ochwepheshe. Ongoti baphinde baveze ukuthi udinga ukushintsha isisefo sikaphethiloli njalo emuva kuka-25000 XNUMX km. Kodwa futhi kuncike kuphethiloli oyisebenzisayo, uma uphethiloli usezingeni eliphansi, khona-ke lesi senzo sinconywa ukuba senziwe kaningi.
Izinkomba zokuvala isihlungi
Izinkomba eziyinhloko zokuthi isihlungi sivalekile:
- Uma ushayela umqansa, kukudidizela kakhulu;
- Ukwehla okukhulu kwamandla enjini;
- Injini ivamise ukuma;
- Ukwenyuka kokusetshenziswa kukaphethiloli;
- Ukushayela imoto ngenkathi ushayela.
Ikakhulukazi abashayeli abanomnotho bazama ukukopela futhi bageze isihlungi ngamanzi bese besibuyisela emuva. Lokhu ngeke kube lula inqubo, njengoba ukungcola kungena emithanjeni ye-mesh futhi akulula ukuyigeza. Kodwa ngemva kokuhlanza okunjalo, isihlungi silahlekelwa ukuphuma kwayo, okubi nakakhulu emotweni.
Lesi sici sidinga ukuzethemba ngekhwalithi, ngakho-ke sikweluleka ukuthi usebenzise izingxenye zangempela kuphela, nansi abanye abakhiqizi bokuqala bezingxenye zeToyota: ACDelco, Motorcraft kanye neFram.
Kufanelekile ukushintsha isihlungi kuphela emoyeni ovulekile, imfucumfucu iyingozi empilweni futhi ingaholela emlilweni, kunconywa ukulungiselela isicishamlilo ngaphambi komsebenzi. Ungabhemi noma ubase umlilo eduze komshini. Sikweluleka ukuthi unqamule ibhethri ukuze ugweme izinhlansi. Kubuye kunconywe ukuqapha izinga lokucindezela ohlelweni.
Ishintsha isihlungi
Ngenxa yokuthi izihlungi zihlukile ekwakhiweni, i-algorithm yokufaka esikhundleni sazo izohluka. Nokho, isibonelo, kwakhethwa imoto - Toyota Yaris. Okokuqala, sinciphisa ingcindezi ohlelweni. Ukuze senze lesi senzo, sizosusa i-fuse fuse fuse, etholakala eduze kweknob yegiya. Le nqubo ivimbe iphampu futhi manje singakwazi ukuqala injini. Ngemuva kokulinda imizuzu engu-1-2, injini izomisa, okuzoba uphawu olucacile lokwehla kwengcindezi ohlelweni lukaphethiloli. Manje ake siqhubekele esondweni elingakwesokudla, lapho isihlungi ngokwaso sitholakala khona. Itholakala kwesokudla, eduze kwethangi likaphethiloli. Khipha iphampu ngokucindezela ama-latches. Khipha isihlungi esidala. Qaphela lapho ufaka, umcibisholo osesihlungini kufanele uhambe ngendlela yokugeleza kukaphethiloli. Sibuyisela i-fuse yamafutha futhi, uma kunesidingo, "khanyisa" imoto. Ngenxa yokungalingani kwengcindezi ohlelweni lukaphethiloli, imoto ngeke iqale okokuqala, udinga ukulinda isikhathi esithile kuze kube yilapho ukucindezela ohlelweni kuzinza.
Asiqaphele ukuthi lalingekho isisefo ezimotweni ezindala futhi kwakumele umshayeli azixhume ngokwakhe. Ikesi elijwayelekile yilapho lokhu kwenziwa esigabeni somugqa wokumunca, ngqo phambi kwepompo likaphethiloli. Kuyafaneleka ukucabangela iqiniso lokuthi kukhona amamodeli wesimanje ngaphandle kwesihlungi, kanye nalawo afakwe umjovo awanawo amaphampu. Njengesibonelo, iFord Focus neMondeo bezingenazo izihlungi zisuka nje, futhi le yunithi ayifakwanga kwaRenault Logan cishe eminyakeni emihlanu edlule. Uma uthanda, ungabuyisela uhlelo ngokwakho, kepha kumamodeli anamuhla lokhu akunandaba: kufakazelwe ngokunamandla ukuthi igridi iguga cishe ngasikhathi sinye nepompo uqobo. Kulesi simo, umhlangano kufanele ushintshwe ngokuphelele, okuyinto ngokwayo iyinjabulo ebiza kakhulu, futhi iyinkimbinkimbi futhi ibuhlungu, njengoba ipompo ngokuvamile itholakala endaweni engafaneleki, futhi ayikho i-hatch yezobuchwepheshe.
Nakuba kukhona amamodeli angenawo okokuhlunga, amamodeli angaba nokuhlelwa okuhlukile kwesihlungi. Isihlungi singaba kude; noma uhambe ne-cartridge eshintshwayo, etholakala ngqo empompini yamafutha. Amathiphu akhipheka kalula ayisici sokuxhuma kulayini kaphethiloli. Ukuze uwasuse, udinga ukusebenzisa i-round-nose pliers.
