Ntchito yayikulu

1.Kuti mupeze kuchuluka kwa kuyeretsa mpweya wotulutsa mpweya komanso kuchepetsa zigawo za (CO) carbon monoxide, (HC) hydrocarbons ndi (NOx) nitrogen oxides mu mpweya wotulutsa mpweya, magalimoto a EFI ayenera kugwiritsa ntchito njira zitatu zosinthira catalytic. Komabe, kuti mugwiritse ntchito bwino chosinthira chothandizira chanjira zitatu, ndikofunikira kuwongolera molondola chiŵerengero chamafuta a mpweya kuti nthawi zonse chizikhala pafupi ndi chiŵerengero cha mpweya-mafuta. Chothandizira nthawi zambiri chimayikidwa pakati pa manifold otopetsa ndi muffler. Sensa ya okosijeni imakhala ndi mawonekedwe kuti mphamvu zake zotulutsa zimasintha mwadzidzidzi pafupi ndi chiŵerengero chamafuta a mpweya (14.7: 1). Khalidweli limagwiritsidwa ntchito pozindikira kuchuluka kwa okosijeni mu gasi wotopa ndikubwezeretsanso ku kompyuta kuti muwongolere kuchuluka kwamafuta a mpweya. Pamene chiŵerengero chenicheni cha mpweya-mafuta chikukhala chapamwamba, kuchuluka kwa mpweya mu mpweya wotuluka kumawonjezeka ndipo kachipangizo ka oxygen kumadziwitsa ECU za chikhalidwe chowonda cha osakaniza (mphamvu yaing'ono ya electromotive: O volts). Pamene chiŵerengero cha mpweya-mafuta ndi otsika kuposa theoretical mpweya-mafuta chiŵerengero, ndende ya okosijeni mu mpweya mpweya amachepetsa, ndi dziko kachipangizo mpweya (yaikulu electromotive mphamvu: 1 volt) amadziwitsidwa kompyuta ECU.

2.ECU imaweruza ngati chiŵerengero cha mpweya-mafuta ndi otsika kapena apamwamba malinga ndi kusiyana kwa mphamvu ya electromotive kuchokera ku sensa ya okosijeni, ndikuwongolera nthawi ya jekeseni wa mafuta moyenerera. Komabe, ngati chopatsira okosijeni chili ndi vuto ndipo mphamvu ya electromotive yotulutsa ndi yachilendo, makompyuta a ECU sangathe kuwongolera molondola kuchuluka kwamafuta a mpweya. Chifukwa chake, sensa ya okosijeni imathanso kupanga cholakwika cha chiŵerengero chamafuta a mpweya chifukwa cha kuvala kwa makina ndi mbali zina za dongosolo la EFI. Titha kunena kuti ndiye sensa yokhayo "yanzeru" mu dongosolo la EFI.

3. Ntchito ya sensa ndiyo kudziwa ngati pali mpweya wochuluka mu mpweya wotuluka mu injini pambuyo pa kuyaka, ndiko kuti, mpweya wa okosijeni, ndikusintha zomwe zili ndi mpweya kukhala chizindikiro chamagetsi ndikuzitumiza ku kompyuta ya injini, kuti injiniyo imatha kuzindikira kuwongolera kotsekeka ndi mpweya wowonjezera ngati cholinga; Onetsetsani kuti chosinthira chothandizira chanjira zitatu chimakhala ndi mphamvu yosinthira kwambiri ma hydrocarbon (HC), mpweya wa carbon monoxide (CO) ndi ma nitrogen oxides (NOX) mu gasi wotulutsa mpweya, ndikusintha ndikuyeretsa kwambiri zowononga zomwe zatulutsidwa.

Chiyambi chakugwiritsa ntchito

Masensa okosijeni amagwiritsidwa ntchito kwambiri mumafuta, makampani opanga mankhwala, malasha, zitsulo, kupanga mapepala, chitetezo chamoto, kayendetsedwe ka tauni, mankhwala, magalimoto, kuyang'anira umuna wa gasi ndi mafakitale ena.
