Sefa yemafuta
Iyo sefa yemafuta mumotokari chinhu chakakosha chehuti system inosefa zvimedu zvidiki zvengura uye guruva, uye zvakare inodzivirira kuti isapinda mumutsara wemafuta. Mukusavapo kwesefa uye ine nzvimbo shoma inoyerera mumutsara wemafuta, zvimedu zveguruva uye ngura zvinovhara system, kudzivirira kupihwa kwemafuta kune injini.
Iyo sefa system yakakamurwa kuita zvikamu zviviri zvekusefa. Nhanho huru uye yekutanga yekuchenesa mafuta ndeyekuchenesa kwakashata, iyo inobvisa zvidimbu zvakakura zvetsvina kubva mumafuta. Chikamu chechipiri chekuchenesa ndechekuchenesa mafuta, iyi sefa yakaiswa pakati petangi yemafuta uye injini inokubvumira kubvisa zvimedu zvidiki zvetsvina.
Mhando uye zvikamu zvemasefa
Zvichienderana nehurongwa hwemafuta, firita yakanaka inosarudzwa nekuda kwezvikonzero zvekuti sefa yega yega yega yega system inosiyana mukugadzira.
Naizvozvo, isu tine marudzi matatu emafirita zvichienderana nemafuta ekupa system:
- Carburetor;
- Jekiseni;
- Dhiziri.
Mafirita akakamurwawo muzvikamu zviviri: huru (iyo iri mumutsara wemafuta pachayo (semuenzaniso: gidhi mutangi), pamwe nekunyudza - inoiswa mutangi pamwe nepombi.
Iyo coarse mafuta sefa ndeye mesh sefa, pamwe neanoratidzira, mesh ine ndarira uye haitenderi zvidimbu zvakakura kupfuura 0,1 mm kupinda. Saka, sefa iyi inobvisa tsvina yakakura kubva mumafuta. Uye iyo sefa iyo pachayo inowanikwa mugirazi, iyo inosungirirwa nemhete diki uye peya yemabhoti. Paronite gasket inovhara mukaha pakati pegirazi nemuviri. Uye pasi pegirazi pane pacifier inokosha.
Saka, sefa inochenesa isati yapinda peturu. Zvakare, iyo sefa yemafuta inoshandisa vharafu yekudzikisa jekiseni, iyo inogadzirisa kumanikidza kwekushanda mumafuta system, zvese izvi zvinoiswa mukuwedzera kune yakananga jekiseni system. Uye mafuta akawandisa anogona kudzoserwa kutangi remafuta. Mudhiziri system, sefa inoshandiswa nenzira imwecheteyo, asi ine dhizaini yakasiyana.
Kana iyo sefa yemafuta ichizotsiviwa iwe pachako, iwe unofanirwa kutanga waona nzvimbo yesefa. By default zvichave:
- Pasi pepasi pemotokari;
- Mune tangi yemafuta (mesh mutangi);
- Injini yekamuri.
Iyo sefa yemafuta inogona kushandurwa nyore nyore pasina rubatsiro rwenyanzvi, asi kana iwe uchikahadzika kugona kwako, unogona kukumbira zano kubva kune vane ruzivo rwemotokari kana kubvunza nyanzvi. Uyewo, nyanzvi dzinoratidza kuti unofanira kuchinja mafuta sefa ose 25000 km. Asi zvakare zvinoenderana nemafuta aunoshandisa, kana mafuta ari emhando yakashata, saka chiito ichi chinokurudzirwa kuti chiitwe kakawanda.
Sefa Clogging Indicators
Zviratidzo zvikuru zvekuti sefa yakavharwa:
- Paunenge uchityaira uchikwidza, inokukwenya zvakanyanya;
- Kudonha kwakapinza kwesimba reinjini;
- Injini inowanzomira;
- Kuwedzera kushandiswa kwemafuta;
- Kurova mota uchityaira.
Kunyanya vatyairi vehupfumi vanoedza kubiridzira uye kugeza sefa nemvura vozoidzorera zvakare. Izvi hazvizoiti kuti hurongwa huve nyore, sezvo tsvina yakanyura mufibers ye mesh uye haisi nyore kuisuka. Asi mushure mekuchenesa kwakadaro, iyo sefa inorasikirwa nekubuda kwayo, izvo zvakatonyanya kuipa kumotokari.
Ichi chinhu chinoda chivimbo mumhando, saka tinokupa zano kuti ushandise zvikamu zvepakutanga chete, heano mamwe evagadziri vekutanga ezvikamu zveToyota: ACDelco, Motorcraft uye Fram.
Zvakakosha kushandura sefa chete mumhepo yakashama, utsi hwemafuta hune ngozi kune hutano uye hunogona kutungamirira kumoto, zvinokurudzirwa kugadzirira moto wemoto usati washanda. Usapfute kana kubatidza moto pedyo nemuchina. Tinokupa zano kuti ubvise bhatiri kuti udzivise sparks. Inokurudzirwawo kutarisa chiyero chekumanikidza muhurongwa.
Sefa kutsiva
Nekuda kwekuti mafirita akasiyana mukugadzira, iyo algorithm yekuvatsiva ichave yakasiyana. Zvisinei, somuenzaniso, motokari yakasarudzwa - Toyota Yaris. Chokutanga pane zvose, tinoderedza kudzvinyirira muhurongwa. Kuti tiite chiito ichi, tichabvisa fuse yepombi yemafuta, iyo iri pedyo negiya knob. Iyi nzira yakadzima pombi uye ikozvino tinogona kutanga injini. Mushure mekumirira 1-2 maminetsi, injini ichamira, iyo ichava chiratidzo chakajeka chekudonha kwekumanikidzwa muhuni. Zvino ngatiendei kuvhiri rekurudyi, uko kune sefa pachayo. Iri kurudyi, pedyo netangi remafuta. Sunungura pombi nekudzvanya marashi. Bvisa sefa yekare. Chenjerera paunenge uchiisa, museve uri pasefa unofanirwa kuenda munzira yekuyerera kwemafuta. Isu tinodzosera fuse yemafuta uye, kana zvichidikanwa, "vhenekera" mota. Nekuda kwekusaenzana mukudzvinyirirwa muhurongwa hwemafuta, mota haizotanga kekutanga, iwe unofanirwa kumirira imwe nguva kusvika kudzvanywa muhurongwa kwadzikama.
Ngationei kuti pakanga pasina sefa pamotokari dzechikuru uye mutyairi aifanira kuzvibatanidza. Mhosva yakajairika ndeye apo izvi zvakaitwa muchikamu chemutsara wekusveta, zvakananga pamberi pepombi yemafuta. Zvakakodzera kufunga nezve chokwadi chekuti kune mamodheru emazuva ano asina sefa, pamwe neayo akashongedzerwa jekiseni haana pombi. Semuenzaniso, Ford Focus neMondeo vaive vasina mafirita kubva pakutanga, uye chikwata ichi chakaiswa kunze kweRenault Logan makore mashanu apfuura. Kana uchida, iwe unogona kudzoreredza sisitimu iwe pachako, asi mumhando dzemazuva ano izvi hazvina basa: zvakaratidzwa zvine simba kuti grid inopera kanenge panguva imwe chete nepombi pachayo. Muchiitiko ichi, gungano rinofanira kuchinjwa zvachose, iro pacharo rinodhura rinodhura, pamwe chete rakaoma uye rinorwadza, sezvo pombi inowanzowanikwa munzvimbo isina kunaka, uye hapana tekinoroji hatch.
Kunyange paine mamodheru asina sefa, mamodheru anogona zvakare kuve neakasiyana sefa kuronga. Sefa inogona kunge iri kure; kana kuenda nekaturiji inotsiviwa, iyo inowanikwa zvakananga mupombi yemafuta. Mazano anobviswa nyore nyore chinhu chekubatanidza chemutsara wemafuta. Kuti uzvibvise, iwe unofanirwa kushandisa round-nose pliers.
