Kodi ntchito ya choyezera mpweya wa galimoto ndi yotani?
Yesani kuchuluka kwa mpweya wolowa ndikuwongolera momwe mafuta amalowetsedwa
Ntchito yaikulu ya choyezera mpweya wa galimoto ndi kuyeza mpweya wolowa mu injini ndikutumiza chizindikiro ku chipangizo chowongolera zamagetsi (ECU) kuti chiwongolere bwino kuchuluka kwa mafuta omwe amalowa, motero kukulitsa mphamvu ya kuyaka, kuchepetsa mpweya woipa, komanso kukulitsa magwiridwe antchito a mphamvu. Ntchito zinazake ndi izi:
- Kuwunika nthawi yeniyeni kuchuluka kwa mpweya wolowa: Pozindikira liwiro la mpweya pogwiritsa ntchito thermistor kapena vortex sensor, kuchuluka kwa mpweya kumasinthidwa kukhala chizindikiro chamagetsi (monga kusintha kwa kukana kapena chizindikiro cha pafupipafupi) kuti zitsimikizire kuti ECU yapeza deta yolondola.
- Kulamulira chiŵerengero cha mpweya ndi mafuta: ECU imasintha mphamvu ya mafuta potengera deta ya kayendedwe ka mpweya, kusunga chiŵerengero choyenera cha mpweya ndi mafuta (pafupifupi 14.7:1), kupewa kudzaza kwambiri (kumayambitsa kusonkhanitsa kwa kaboni ndi kugwiritsa ntchito mafuta mopitirira muyeso) kapena kuyaka mopitirira muyeso (kumabweretsa kutaya mphamvu).
- Kusintha momwe zinthu zimagwirira ntchito: Imayankha mwachangu (mkati mwa ma milliseconds) panthawi yogwira ntchito, kuthamanga, kapena kuchepa kwa liwiro, mwachitsanzo, kuwonjezera mafuta kuti awonjezere mphamvu panthawi yogwira ntchito komanso kusunga mpweya wokhazikika kuti injini isayime panthawi yogwira ntchito.
Zizindikiro zazikulu zikachitika kuti chipangizo choyezera mpweya mgalimoto sichikugwira ntchito bwino:
- Kusakhazikika kwa ntchito
- Kuthamanga kofooka
- Kuchuluka kwa mafuta omwe amagwiritsidwa ntchito
- Utsi wakuda wochokera mu chitoliro chotulutsa utsi
- Injini imayima kapena kugwedezeka nthawi ndi nthawi
- Mawonekedwe enieni:
Zizindikiro za vuto lalikulu
Choyezera mpweya chomwe chawonongeka chingayambitse kuzindikira kuchuluka kwa mpweya womwe ulowa, zomwe zimakhudza kuwongolera kwa mafuta ndipo zimayambitsa mavuto wamba:
- Kusakhazikika kwa injini: Injini imagwedezeka kwambiri ikagwira ntchito kapena ikathamanga pang'ono, ma RPM osinthasintha, komanso ngakhale kuyima (chifukwa cha kulephera kwa ECU kusintha molondola chiŵerengero cha kusakaniza).
- Kuthamanga pang'ono: Injini imayankha pang'onopang'ono ikaponda accelerator, zomwe zimapangitsa kuti zikhale zovuta kupitirira (makamaka pa liwiro lalikulu, monga pamene liwiro likupitirira 120 km/h ndipo RPM ikutsika).
- Kuchuluka kwa mafuta ogwiritsidwa ntchito molakwika: Kugwiritsa ntchito mafuta kumawonjezeka ndi 10%-15%, chifukwa cha kuwerengera kolakwika kwa kuchuluka kwa mafuta omwe amalowetsedwa, zomwe zimapangitsa kuti mafuta azichuluka kwambiri (kupangitsa kuti mpweya uchuluke komanso kuti mafuta azigwiritsidwa ntchito mopitirira muyeso) kapena kuti mafuta aziyaka pang'ono kwambiri (kupangitsa kuti magetsi achepe).
- Utsi wakuda wochokera mu chitoliro chotulutsa utsi: Kuyaka kosakwanira kumabweretsa utsi wakuda wambiri, womwe umaphatikizidwa ndi kuipitsidwa kwambiri kwa utsi wotulutsa utsi (utsi wa HC ukhoza kupitirira 500 ppm).
- Kuyima kapena kugwedezeka kwa injini nthawi ndi nthawi: Injini imagwedezeka mwadzidzidzi kapena kuyima ikayendetsa mofulumira kwambiri, ndipo imagwira ntchito bwino nthawi zonse (chifukwa cha kutulutsa kwa chizindikiro cha liwiro lalikulu kolakwika).
Zotsatira zina zogwirizana nazo
- Kuwala kwa chizindikiro cholakwika: Dashboard imayatsa chizindikiro cholakwika cha injini (monga "SERVICE ENGINE").
- Kuvuta kuyatsa injini: N'kovuta kuyatsa injini ikayamba kuzizira chifukwa chakuti ECU singathe kufanana ndi chiŵerengero choyenera cha mpweya ndi mafuta.
- Kuopsa kwa kuwonongeka kwa nthawi yayitali: Kulephera kugwira ntchito nthawi zonse kungapangitse injini kuwonongeka komanso kuchepetsa mphamvu ya kupsinjika kwa silinda.
Ngati zizindikiro zomwe zili pamwambapa zichitika, tikukulimbikitsani kuti zikonzedwe mwachangu kuti zisamawononge zinthu monga chosinthira magetsi cha njira zitatu.
Choyezera mpweya mgalimoto chimatha kutsukidwa, koma nthawi zambiri chimafunika kutsukidwa kokha ngati chadetsedwa kapena cholakwika.
Kuyeretsa
- Ikhoza kutsukidwa: Pamene mpweya kapena dothi lasonkhana pa masensa amkati a chipangizo choyezera mpweya, kuyeretsa kumatha kubwezeretsa kulondola kwake ndikuthetsa mavuto monga kusowa kwa mphamvu ya injini komanso kuchuluka kwa mafuta omwe amagwiritsidwa ntchito.
- Sikofunikira: Mu galimoto yosamalidwa bwino, choyezera mpweya nthawi zambiri chimakhala choyera ndipo sichifuna kutsukidwa nthawi zonse.
Njira zoyeretsera ndi zodzitetezera
- Malo ndi kusokoneza: Choyezera mpweya nthawi zambiri chimakhala pa fyuluta ya mpweya kumbuyo kwa chitoliro cholowera mpweya. Kusokoneza mpweya kumafuna kugwiritsa ntchito zida zaukadaulo kuti tipewe kuwonongeka.
- Ntchito yoyeretsa:
- Kuyeretsa kunja: Gwiritsani ntchito nsalu yosalukidwa yoviikidwa mu mowa kuti mupukute madontho a mafuta omwe ali pa chivundikirocho.
- Zosewerera mkati: Gwiritsani ntchito thonje loviikidwa mu mowa wa 95% kapena kuposerapo kapena zotsukira zamagetsi zapadera kuti mupukute pang'onopang'ono zosewerera waya/thermistor za platinamu. Musagwiritse ntchito zotsukira zowononga (monga zotsukira za carburetor).
- Kuyeretsa gridi: Gwiritsani ntchito burashi yofewa kuti muyeretse zinyalala zomwe zili pa gridi.
- Kuumitsa ndi kubwezeretsanso: Gwiritsani ntchito chowumitsira tsitsi kuti muumire bwino zinthuzo, kuonetsetsa kuti ziume bwino musanaziyikenso, ndipo samalani kuti mawaya alumikizane bwino.
- Mafotokozedwe aukadaulo:
- Kusankha zinthu zotsukira: Zinthu zotsukira zamagetsi zokha kapena ethanol yopanda madzi (kuchuluka kwa ≥ 95%) ndizololedwa. Gwiritsani ntchito mofatsa: Zigawo za sensa ndizosavuta. Mphamvu yopukuta iyenera kukhala yopepuka kuti isawonongeke.
Mukamaliza kuyiyika, yang'anani: Mukamaliza kuyeretsa, yatsani injini ndikuwona momwe ikuyendera. Ngati pali khodi yolakwika, chitani ECU adaptive learning.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
