Sensa yamsewu yovuta ndi adsorber yamagalimoto - ndi chiyani ndipo amagwira ntchito bwanji

Kubwera kwa injini za jakisoni, masensa ambiri awonjezedwa kuti apititse patsogolo mphamvu komanso magwiridwe antchito a chilengedwe. M'nkhaniyi, tikhudza kachipangizo kakang'ono kamene kamadziwika bwino ndikulankhula za chotsitsa - chomwe chiri komanso chifukwa chake chikufunikira. 

Kodi DND ndi chiyani?

Chojambulira cha mseu ndi kachipangizo kakang'ono kamene kamazimitsa makina opangira injini kuti Check Engine isamawonetseke nthawi zonse pa desibodi nthawi yolakwika. Chojambuliracho chimakhala ndi ntchito yoteteza. Pa ma injini omwe ali ndiyezo wa chilengedwe cha Euro-3 komanso pamwambapa, omwe akuyenera kulowa mgululi ayenera kuchitapo kanthu nthawi yomweyo akadzawonongeka, chifukwa izi zimapitilira miyezo yotulutsa mpweya. Pafupifupi, zolakwika zinayi zimachitika pazaka 100 zogwirira ntchito, chifukwa chake makampani amakono agalimoto ayamba kale kudera nkhawa za kukhazikitsidwa kwa matenda ozindikira omwe ali mgalimoto.

Mwambiri, sensa yokhotakhota imafunika kuti izindikire ndikuwona kugwedezeka kwamphamvu komwe kumakhudza magwiridwe antchito a injini.

Kodi adsorber ndi chiyani?

Pambuyo pa kukhazikitsidwa kwa miyezo ya poizoni ya EURO-1, panafunika kuwongolera kwakukulu kotulutsa mpweya m'mlengalenga, komanso kuwongolera kutuluka kwa mafuta. Makina otsatsira mafuta salola kuti mpweya wa mafuta ulowe mumlengalenga, potero umathandizira driver ndi okwera kununkhira kwa mafuta, potero kumawonjezera kuyanjana kwachilengedwe komanso miyezo yachitetezo chamoto.

Mu adsorber palokha pamakhala mpweya wokhazikika womwe umayamwa zinthu zonse zovulaza pomwe injini siyimayendetsa. Njirayi imatchedwa EVAP ndipo imagwira ntchito motere:

• kumapeto kwa ntchito ya injini, nthunzi imatuluka mu thanki yamafuta, yomwe imakwera ndi khosi lodzaza mafuta ndikukhala panja, ndikupanga kupsinjika kowopsa mu thankiyo;
• olekanitsa amaperekedwa pafupi ndi khosi, lomwe limalekanitsa madziwo ndi nthunzi, yomwe imadutsa m'mipope yapadera kubwerera mu thankiyo ngati mafuta condensate;
• nthunzi zotsalira, zomwe olekanitsawo sanathe kulimbana nazo, zimalowa mu adsorber, ndipo atayamba injini kudzera mu valavu yampweya, nthunzi ya mafuta imalowa m'malo ochulukirapo, kenako ndikumagetsi a injini.

Kodi makina oyang'anira misfire amagwira ntchito bwanji?

Injini iliyonse ya jekeseni imakhala ndi njira yodziyesera yokhayokha kuti ipse. Chojambulira cha crankshaft chimayikidwa pafupi ndi crankshaft pulley, chomwe ndi chinthu chamagetsi chamagetsi chomwe chimawerenga kuthamanga ndi kukhazikika kwa kasinthasintha ka pulley, ndipo chimapereka maginito oyang'anira injini. 

Ngati sensa itazindikira kusinthasintha kosakhazikika, kuwunika kosasunthika kumachitika nthawi yomweyo, pambuyo pake "cholakwika cha Injini" chitha kuwoneka pagulu lazida, ndipo sikani yolumikizira ikalumikizidwa, mbiri yoyipa idzawonekera mu lipotilo.

Kodi sensa yokhotakhota imagwira ntchito bwanji?

Sensa, kutengera mawonekedwe agalimoto, nthawi zambiri imayikidwa kutsogolo kwa membala wakutsogolo, imathanso kukhala pa chimango kapena kuyimitsidwa. Ntchito yake imachokera pa mfundo ya piezoelectric element - mphamvu zamagetsi zimapangidwira panthawi yosinthika. Mwa njira, mfundo yogwirira ntchito ikufanana ndi sensor yogogoda. 

Ngati mapangidwe a piezoelectric element apitilira mulingo wololedwa, ndiye kuti pakatulutsira kachipangizo kamayimba kayendedwe ka msewu wosagwirizana. 

Chifukwa chiyani ndikufunika chojambulira chamisewu choyipa?

Mukamayendetsa pamsewu wosagwirizana, pakhoza kukhala vuto lomwe gudumu limaphwanya pang'ono, lomwe pakadali pano limabweretsa kusintha kosinthasintha kwa crankshaft. Chifukwa cha kachipangizo kazitsulo kosalala kwambiri, kupatuka pang'ono kumawoneka ngati cholakwika pamoto.

Chifukwa chakupezeka kwa DND, kuwunika zolakwika kosalekeza kumayimitsidwa kwakanthawi, ndipo pamagalimoto amakono kwambiri, kuyatsa kumasunthira kuchedwa, chifukwa cha kuyatsa kwapamwamba kwambiri kwa chisakanizocho. 

Ndi liti ndipo ndichifukwa chiyani sensa yamisewu yoyipa idawonekera pamagalimoto?

Makina opanga magalimoto atangolingalira mozama za chilengedwe, miyezo ya Euro idayambitsidwa. Mu 1995, kukhazikitsidwa kwa Euro-2, komwe kumapangitsa kuti galimoto ikhale ndi chothandizira, motsatana, ndi masensa kuti azindikire mpweya m'mafuta otulutsa utsi. Pakadali pano, magalimoto onse anali ndi masensa oyipa amisewu.

Malingaliro oyambitsa kukhazikitsidwa kwa DND ndiosavuta: mafuta osayaka amawononga mwachangu chosinthira cha ceramic. Chifukwa chake, kukonza zolakwika kumakupatsani mwayi wosiya mafuta mu silinda momwe chisakanizocho sichinayatseke, chomwe chimakupatsani mwayi wopulumutsa chothandizira ku zovuta zina.

Ngati kupsa mtima kumakonzedwa mwachisawawa, mu masilindala osiyanasiyana, Injini Yoyang'ana ikukudziwitsani za izi - ndizomveka kupanga diagnostics zamakompyuta agalimoto.

Ngati zolakwikazo zikugwirizana ndi ntchito ya rough road sensor, nyali yochenjeza siyaka.

Pomaliza

Chifukwa chake, sensa yamsewu yoyipa ndi adsorber ndi zinthu zofunika kwambiri mu dongosolo lovuta la injini yoyaka moto. Kugwira ntchito kwa sensa yamsewu yoyipa kumakupatsani mwayi wopewa kuwerengera zabodza pamoto, komanso kutulutsa zinthu zochepa zovulaza mumlengalenga, komanso, adsorber sikuti amangosamalira chilengedwe, komanso thanzi la dalaivala ndi okwera. .

Mafunso ndi Mayankho:

Kodi rough road sensor ili kuti? Zimatengera mtundu wagalimoto. Pokhala ndi dongosolo la ABS, sensa iyi ikhoza kukhala (dongosolo lokha limagwira ntchito yake). Ngati dongosololi silikupezeka, ndiye kuti sensa imayikidwa m'dera la gudumu lakumanja lakumanja, mwachitsanzo, pamapiko.
