Ntchito ya sensa ya okosijeni m'magalimoto
Ntchito yaikulu ya sensa ya okosijeni yamagalimoto ndikuwunika kuchuluka kwa okosijeni mu mpweya wotulutsa utsi ndikubwezera chidziwitsocho ku unit yowongolera injini (ECU) kuti ikwaniritse bwino chiŵerengero cha mpweya ndi mafuta, kukonza mafuta osawononga komanso kuchepetsa mpweya woipa.
Youdaoplaceholder0 Core function
Youdaoplaceholder0 kuyang'anira kuchuluka kwa mpweya wotulutsa mpweya : Sensor ya mpweya imazindikira kuchuluka kwa mpweya mu mpweya wotulutsa mpweya kudzera mu chinthu chodziwika bwino cha ceramic, imasintha kuchuluka kwa mpweya kukhala chizindikiro cha magetsi ndikuchitumiza ku ECU kuti ikwaniritse kulamulira kotsekedwa.
Youdaoplaceholder0 Konzani chiŵerengero cha mpweya ndi mafuta : Mwa kusintha kuchuluka kwa mafuta omwe amalowa mu injini nthawi yeniyeni, onetsetsani kuti injini ikugwira ntchito motsatira chiŵerengero cha mpweya ndi mafuta (14.7:1), motero kumawonjezera mphamvu yotulutsa ndi kuyaka bwino.
Ntchito yeniyeni ya ndi
Youdaoplaceholder0 Pre-oxygen sensor : Ili patsogolo pa chosinthira mphamvu cha njira zitatu, imayang'anira mwachindunji kuchuluka kwa mpweya mu mpweya wotulutsa utsi pambuyo poyaka, kupereka deta yeniyeni pa kuchuluka kwa chisakanizocho ku ECU.
Youdaoplaceholder0 Sensa ya mpweya wotsatira mpweya : Yopezeka pambuyo pa chosinthira mpweya cha njira zitatu, imazindikira kuchuluka kwa mpweya wotuluka mu utsi woyeretsedwa. Poyerekeza deta ndi ya sensa ya pre-oxygen, zitha kudziwika ngati chosinthira mpweya cha njira zitatu chalephera.
Youdaoplaceholder0 kufunika
Youdaoplaceholder0 Chepetsani kugwiritsa ntchito mafuta : Kuwongolera bwino kuchuluka kwa mpweya ndi mafuta kungachepetse kutayika kwa mafuta, ndipo kugwiritsa ntchito mafuta kungawonjezere ndi 10% mpaka 20% pakagwa vuto.
Youdaoplaceholder0 kuteteza chilengedwe ndi kuchepetsa utsi woipa : Chepetsani zinthu zoipitsa monga HC, CO, ndi NOx mu mpweya wotulutsa utsi kudzera mu kuyaka kwathunthu kuti mukwaniritse miyezo ya utsi woipa.
Chitetezo cha Youdaoplaceholder0 cha chosinthira mphamvu cha njira zitatu : Chiŵerengero chosazolowereka cha mpweya ndi mafuta chingapangitse chosinthira mphamvu kutentha kwambiri kapena kutsekeka. Chowunikira mpweya chingateteze ntchito yake mwanjira ina.
Kulephera kugwira ntchito bwino kwa sensa ya okosijeni m'galimoto kungayambitse mavuto monga kuchepa kwa magwiridwe antchito a injini, kuchuluka kwa mafuta omwe amagwiritsidwa ntchito komanso kutulutsa utsi wambiri. Kuzindikira matenda ndikofunikira musanayeretse kapena kusintha.
Youdaoplaceholder0 Zizindikiro zachikale za zolakwika
Youdaoplaceholder0 Kusakhazikika kwa mphamvu zamagetsi: kuchedwa kwa liwiro, kugwedezeka kosagwira ntchito, mphamvu yosakwanira yokwera, kugwiritsa ntchito mafuta kungawonjezere ndi 15%-30%.
Chenjezo la Youdaoplaceholder0 la kutulutsidwa kwa mpweya: Kuwala kwa injini kumakhalabe koyaka nthawi zonse. Pa nthawi yoyesa mpweya wotulutsa utsi, zinthu zoipitsa monga CO/HC zimapitirira muyezo ndi nthawi 3 mpaka 4. Chiwopsezo cholephera kuwunika pachaka n'chokwera.
Youdaoplaceholder0 Zizindikiro zochenjeza : Utsi wakuda wochokera mu chitoliro chotulutsa utsi, utsi wabuluu panthawi yozizira, ndi phokoso losazolowereka m'chipinda cha injini.
Youdaoplaceholder0 njira yodziwira matenda ndi kukonza
Youdaoplaceholder0 Chitsimikizo cha cholakwika .
Gwiritsani ntchito chida chodziwira matenda a OBD kuti muwerenge khodi yolakwika (nthawi zambiri mndandanda wa P0130-P0134).
Yang'anani ngati chizindikiro cha magetsi cha sensa ya okosijeni chimasinthasintha bwino mkati mwa 0.1-0.9V (nthawi zambiri nthawi 5-8 pa sekondi).
Ndondomeko yokonza ya Youdaoplaceholder0: sankhani .
Kuti muchepetse mpweya woipa, mutha kuyesa kuviika mu chotsukira chapadera (pa mitundu yotenthetsera, chotsukiracho chiyenera kuchotsedwa).
Kukalamba kapena kuwonongeka kumafuna kusinthidwa. Ndikofunikira kusankha zida kuchokera ku makampani monga Bosch ndi NGK.
Njira zosinthira za Youdaoplaceholder0 .
Chotsani malo olumikizira batire kuti mupewe ma circuit afupikitsa.
Gwiritsani ntchito wrench yapadera kuti muchotse (poperani chomasula ngati pakufunika).
Mphamvu yoyika iyenera kuyendetsedwa mkati mwa 30 mpaka 50N·m.
Pambuyo posintha, ECU iyenera kubwezeretsedwanso ndipo mayeso ayenera kuchitika.
Youdaoplaceholder0 zodzitetezera
Youdaoplaceholder0 Chitetezo cha ntchito : Ntchito iyenera kuchitika injini ikazizira bwino kuti isapse ndi kuwonongeka kwa zigawo zake.
Youdaoplaceholder0 Kufananiza kwa chitsanzo : Mafotokozedwe a mawonekedwe a mitundu yosiyanasiyana amatha kusiyana. Ndikofunikira kutsimikizira nambala yoyambirira ya fakitale (mwachitsanzo, masensa a Volkswagen EA888 ndi nsanja ya Toyota TNGA sasinthasintha).
Youdaoplaceholder0 Msampha wokonza : 65% ya zolakwika zinapezeka molakwika ngati mavuto ndi chosinthira cha catalytic cha njira zitatu. Ndikofunikira kuchita kutsimikizira kwa cross-validation kudzera mu data flow.
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.
