Inzwa yomgwaqo engalungile kanye ne-adsorber yemoto - iyini futhi isebenza kanjani

Ngokufika kwezinjini zokujova, inani elibalulekile lezinzwa lengeziwe ukuze kuthuthukiswe amandla nokusebenza kwemvelo. Kulesi sihloko, sizothinta inzwa yomgwaqo engavamile eyaziwa kancane futhi sikhulume nge-absorber - ukuthi iyini nokuthi kungani idingeka. 

Yini i-DND?

Inzwa yomgwaqo enolaka iyithuluzi elincane elicisha okwesikhashana uhlelo lokuxilonga izinjini okwesikhashana ukuze i-Check Engine ingakhonjiswa njalo kuphaneli yensimbi ngesikhathi sokudubula kabi. Inzwa inomsebenzi wokuvikela. Ezinjinini ezinesilinganiso semvelo se-Euro-3 nangaphezulu, uhlelo lokubhoda kufanele lusabele ngokushesha lapho kufakwa iphutha, ngoba lokhu kudlula kakhulu amazinga okuphuma kwegesi. Ngokwesilinganiso, kufika ku-100 misfires ngemijikelezo yokusebenza eyi-4, ngakho-ke imboni yezimoto yanamuhla sekuyisikhathi eside iqale ukukhathalela ukwethulwa kwezifo ezibucayi ezitholakala ebhodini.

Ngokuvamile, inzwa yomgwaqo enolaka iyadingeka ukuthola nokuthola ukunyakaza komzimba okunamandla okuthinta ngqo ukusebenza kwenjini.

Yini isikhangiso?

Ngemuva kokwethulwa kwamazinga obuthi e-EURO-1, kwavela isidingo sokulawulwa okuphelele kokukhishwa kwegesi emkhathini, kanye nokulawulwa kokuhwamuka kukaphethiloli. Uhlelo lwe-adsorption aluvumeli umhwamuko kaphethiloli ungene emkhathini, ngaleyo ndlela ukhulule umshayeli nabagibeli ngephunga likaphethiloli, ngaleyo ndlela kwandise ubungani bezemvelo namazinga okuphepha emlilweni.

Ku-adsorber uqobo kunekhabhoni eyenziwe yasebenza emunca zonke izinto eziyingozi lapho injini ingasebenzi. Uhlelo lubizwa nge-EVAP futhi lusebenza kanjena:

• ekugcineni kokusebenza kwenjini, kuqhamuka imiphunga ethangini likaphethiloli, elikhuphukela entanyeni yokugcwalisa uphethiloli futhi lithambekele ngaphandle, lidale ukucindezelwa okuyingozi ngokweqile ethangini;
• kunikezwa isihlukanisi eduze kwentamo, esihlukanisa uketshezi kumhwamuko, ogeleza ngamapayipi akhethekile ubuyele ethangini ngendlela kaphethiloli okhuphuka;
• okusele kwemiphunga, isihlukanisi esingazange sikwazi ukubhekana nayo, faka i-adsorber, futhi ngemuva kokuqalisa injini nge-valve yokungenisa umoya, umusi kaphethiloli ungena ezinhlakeni eziningi zokudla, bese ungena kumasilinda wenjini.

Isebenza kanjani indlela yokuhlola i-misfire?

Noma iyiphi injini yomjovo inesistimu yokuzixilonga yomlilo ngokungafanele. Inzwa yesikhundla se-crankshaft ifakiwe eduze ne-crankshaft pulley, okuyisici se-electromagnetic esifundeka ijubane nokuzinza kokujikeleza kwe-pulley, futhi kunikeze izinhlayiya kwiyunithi yokulawula injini. 

Uma inzwa ithola ukujikeleza okungazinzile, ukuhlola okungafani kahle kwenziwa ngokushesha, ngemuva kwalokho kungavela "Iphutha lenjini" kuphaneli yensimbi, futhi lapho isithwebuli sokuxilonga sixhunywe, kuzovela umlando we-misfire embikweni.

Isebenza kanjani inzwa yomgwaqo enolaka?

Inzwa, kuye ngezici zokuklama zemoto, ivamise ukufakwa kulungu lohlangothi lwangaphambili, ingaphinda ibekwe kuhlaka noma into yokumiswa. Umsebenzi wayo usekelwe kumgomo wesici se-piezoelectric - ama-impulses kagesi akhiqizwa ngesikhathi sokuguqulwa. Ngendlela, umgomo wokusebenza ufana nenzwa yokungqongqoza. 

Uma ukusonteka kwento ye-piezoelectric kudlula izinga elivunyelwe, lapho kukhishwa inzwa isayinda ngokuhamba emgwaqweni ongalingani. 

Kungani ngidinga inzwa yomgwaqo enokhahlo?

Lapho ushayela emgwaqeni ongalingani, kungavela isimo lapho isondo liphuka khona kancane emfuleni, okwamanje okuholela ekuguqukeni kokujikeleza kwe-crankshaft. Ngenxa yenzwa yokujikeleza ye-crankshaft yokunemba okuphezulu, ukuphambuka okuncane kutholwa ngokushesha njengephutha le-misfire.

Ngenxa yobukhona be-DND, ukuqapha amaphutha okuqhubekayo kumisiwe okwesikhashana, futhi ezimotweni zesimanje, ukuthungela kugudluzelwa ekubambezelweni, ngokushisa okukhulu kwekhwalithi yengxube. 

Inzwa yomgwaqo enolaka ivele nini ezimotweni?

Lapho nje abenzi bezimoto beqala ukucabangisisa ngemvelo, kwethulwa amazinga e-Euro. Ngo-1995, kwamukelwa inkambiso ye-Euro-2, ebophezela ukuhlomisa imoto nge-catalyst, ngokulandelana, nezinzwa zokuthola umoya-mpilo emagesi aqeda amandla. Ngalesi sikhathi, zonke izimoto bezihlonyiswe izinzwa zomgwaqo ezinzima.

Umqondo ngemuva kokuqaliswa kwe-DND ulula: uphethiloli ongashiswanga uqeda ngokushesha isiguquli se-ceramic catalytic. Ngakho-ke, ukulungiswa kwamaphutha akuvumela ukuthi umise ukunikezwa kwamafutha kusilinda lapho ingxube ingakavuthanga khona, okukuvumela ukuthi ulondoloze i-catalyst emiphumeleni eyingozi.

Uma ama-misfires alungiswa ngokungahleliwe, kumasilinda ahlukene, i-Check Engine izokwazisa ngalokhu - kunengqondo ukwenza ukuxilongwa kwekhompyutha yemoto.

Uma ama-misfires ahlobene nokusebenza kwenzwa yomgwaqo engalungile, isibani esiyisixwayiso ngeke sikhanyise.

isiphetho

Ngakho-ke, inzwa yomgwaqo engalungile kanye ne-adsorber yizici ezibalulekile ohlelweni oluyinkimbinkimbi lwenjini yangaphakathi yomlilo. Ukusebenza kwenzwa yomgwaqo engalungile kukuvumela ukuthi ugweme ukufundwa okungamanga ekudunyisweni, futhi ukhiphe izinto eziyingozi kancane emkhathini, futhi, i-adsorber ayikhathaleli imvelo kuphela, kodwa futhi nempilo yomshayeli nabagibeli. .

Imibuzo nezimpendulo:

Itholakala kuphi inzwa yomgwaqo? Kuya ngemodeli yemoto. Kulabo abafakwe uhlelo lwe-ABS, le nzwa ingase ingabi khona (isistimu ngokwayo yenza umsebenzi wayo). Uma lolu hlelo lungatholakali, khona-ke inzwa izofakwa endaweni yesondo langaphambili elingakwesokudla, isibonelo, ku-fender.
