I-valve ye-EGR - kuyini futhi ngingayiqeda?

I-valve ye-EGR iyingxenye ethize kakhulu ngaphansi kwesivalo semoto abashayeli abavame ukuba nemizwa exubile ngayo. Kungani? Ngakolunye uhlangothi, kunesibopho sokulawula inani lamagesi okukhipha kanye nezinto eziyingozi kuwo, futhi ngakolunye uhlangothi, yingxenye evame ukuhluleka. Imvamisa, uma imoto iyintsha, intengo yokukhandwa kwayo izoba phezulu. Ngakho-ke, abanye abantu banquma ukuqeda uhlelo lwe-EGR ezimotweni zabo. Ingabe ilungile ngempela?

Uzofundani kulokhu okuthunyelwe?

• Iyini i-valve ye-exhaust gas recirculation?
• Isebenza kanjani?
• Ukususa, ukukhubaza, ukuphuphuthekisa i-EGR - kungani lezi zenzo zinganconywa?

Ngikhuluma nje

Ivalvu ye-EGR inesibopho sokunciphisa inani lamakhemikhali ayingozi akhishelwa emkhathini kanye namagesi akhipha umoya. Ngenxa yalokho, izimoto zethu zithobela izindinganiso zokukhishwa kwe-exhaust ezamukelwa ngokuvamile. Uma isistimu ye-EGR ihluleka, kufanele ihlanzwe noma ifakwe ivalve entsha. Kodwa-ke, akunconywa ukuyisusa, ukuyikhubaza noma ukuyiphuphuthekisa - lokhu kungumsebenzi ongekho emthethweni obangela izinga eliphansi lomoya kanye nokungcoliswa kwemvelo okwengeziwe.

Iyini i-valve ye-exhaust gas recirculation?

I-EGR (Exhaust Gas Recirculation) ngokwezwi nezwi isho i-Exhaust Gas Recirculation Valve. Ifakiwe ku-exhaust yenjini kaningifuthi omunye wemisebenzi yayo eyinhloko ngu ukuhlanzwa kwamagesi e-exhaust kusuka kumakhemikhali amakhemikhali e-carcinogenic - ama-hydrocarbons CH, ama-nitrogen oxides NOx kanye ne-carbon monoxide CO. Okuqukethwe kwalezi zinto kuncike ikakhulukazi ohlotsheni lwengxube yamafutha omoya avuthayo emakamelweni enjini:

• ukushisa ingxube ecebile (uphethiloli omningi, umoya-mpilo omncane) kwandisa ukuhlushwa kwama-hydrocarbons emagesini aphumayo;
• Ukushiswa okuthambile (umoya-mpilo omningi, uphethiloli ophansi) kwandisa ukugcwala kwama-nitrogen oxides ekukhishweni.

I-valve ye-EGR (i-EGR valve) iyimpendulo yokwanda kokungcoliswa kwemvelo kanye nekhwalithi yomoya ewohlokayo, engagcini nje endaweni ezungezile kuphela. Ukukhathazeka ngezimoto, futhi kuyazi ngobungozi, sekunesikhathi kugxile ekuhlinzekeni izixazululo zesimanje, ezisekela imvelo kanye nobuchwepheshe, obuthola ukusebenza okungokoqobo ezimotweni zethu. Phakathi kwazo singathola amasistimu afana neziguquli ze-catalytic, izihlungi ze-particle noma i-valve ye-EGR. Okwakamuva, ngokuphambene nenkolelo evamile, ayilimazi iyunithi yokushayela, okungukuthi, ayithinti kabi ukusebenza kwangempela kwemoto.

I-valve ye-EGR - isimiso sokusebenza

Umgomo wokusebenza kwe-valve yokukhipha i-EGR isekelwe kakhulu "Ukuphefumula" inani elithile legesi ephumayo libuyele enjinini. (ikakhulukazi, ekamelweni elivuthayo), okunciphisa ukukhululwa kwamakhemikhali ayingozi. Amagesi akhipha izinga lokushisa eliphezulu angena kabusha egunjini lomlilo ukusheshisa ukuhwamuka kukaphethiloli futhi ulungiselele kangcono ingxube... Ukujikeleza kabusha ngokuvamile kwenzeka lapho ingxube yamafutha omoya ithambile, okungukuthi, equkethe inani elikhulu lomoya-mpilo. I-flue gas ibe isithatha indawo ye-O2 (ekhona ngokweqile), enciphisa ukugcwala kwama-nitrogen oxides okukhulunywe ngawo ngaphambili. Ziphinde zithinte i-oxidation yalokho okubizwa ngokuthi amaketanga e-hydrocarbon "Aphukile".

I-exhaust gas recirculation systems ihlukaniswe yaba izinhlobo ezimbili eziyinhloko - zangaphakathi nangaphandle:

• Ukujikeleza kabusha kwegesi ephumayo yangaphakathi - kuhilela ukusetshenziswa kwezixazululo ezithuthukisiwe ohlelweni lwesikhathi, kufaka phakathi ukuvala ama-valve okukhiphayo kubambezelekile, futhi ngesikhathi esifanayo ama-valve okungena avuliwe. Ngakho, ingxenye yamagesi aphumayo isala ekamelweni elivuthayo. Uhlelo lwangaphakathi lusetshenziswa kumayunithi anesivinini esikhulu nanamandla aphezulu.
• Ukujikeleza kabusha kwegesi ephumayo yangaphandle - lokhu ngenye indlela i-EGR. Ilawulwa ikhompuyutha, nayo enesibopho senani leminye imingcele ebalulekile yokusebenza yemoto yokushayela. I-valve ye-exhaust gas recirculation iphumelela kakhulu kunesistimu yangaphakathi.

Ingabe i-EGR blinding kuwumkhuba onconyiwe?

I-valve yokukhipha igesi ephumayo, kanye nanoma iyiphi ingxenye ebhekele ukugeleza kwamagesi, ngokuhamba kwesikhathi kuyangcola. Ifaka amadiphozithi - amadiphozi kaphethiloli angashisiwe kanye nezinhlayiya zikawoyela, eziqina ngaphansi kwethonya lokushisa eliphezulu futhi zenze uqweqwe olunzima ukususa. Lena inqubo engenakugwemeka. Ngakho-ke, ngezikhathi ezithile kufanele senze ukuhlanzwa okuphelele kwe-valve ye-exhaust gas recirculation, okungcono uma kunezinkinga ngomsebenzi wayo ongasebenzi kahle - kuhl. ukwanda komlilo, isihlungi sezinhlayiyana esivalekile noma, ezimweni ezimbi kakhulu, ukucisha injini.

Ukuhlanzwa kwe-EGR nokushintshwa

Izinyathelo zesevisi ezigunyaziwe ezihlobene ne-valve yokukhipha igesi ephumayo kabusha ihlobene nokukhanda kwayo (ukuhlanza) noma ukushintshwa ngezwe. Nokho, ngenxa yemibono eyiphutha ngomthelela ongemuhle we-EGR emandleni enjini, abanye abashayeli nomakhenikha bancike kumaqhinga amathathu okulwa nobuciko. Lezi:

• ukususwa kwe-valve ye-recirculation yegesi yokukhipha - kuhlanganisa ukususwa kwesistimu ye-EGR kanye nokushintshwa kwalokho okubizwa ngokuthi i-bypassokuyinto, nakuba ifana ngokuklama, ayivumeli amagesi okukhipha amandla ukungena ohlelweni lokuthatha;
• ukuphuphuthekisa EGR - siqukethe ukuvalwa komshini kokudlula kwayoyini evimbela uhlelo lokusebenza;
• ukucishwa kwe-elekthronikhi kohlelo lokujikeleza kwegesi exhaust - kuqukethe ukuvala ukusebenza unomphela i-valve elawulwa ngogesi.

Lezi zenzo zibuye zidume ngenxa yentengo yazo - i-valve entsha ingabiza cishe ama-zloty angu-1000, futhi ngokuphuphuthekisa uhlelo lokuvuselela igesi ephumayo nokuyihlanza, sizokhokha cishe ama-zloty angu-200. Lapha, nokho, kufanelekile ukuthi ume isikhashana futhi ucabange yimiphi imiphumela emibi ye-valve ye-EGR evalekile.

Okokuqala, kunomthelela oyinhlekelele endaweni ezungezile. Izimoto ezinomshini ocishiwe noma oxhunywe igesi ephumayo ephumayo kabusha idlula ngokuphawulekayo amazinga okuvutha avumelekile. Okwesibili, kwenzeka ukuthi lapho i-valve ivuliwe, i-valve iphutha ohlelweni lokulawula, okuholela ekulahlekelweni kwamandla okushayela (Lokhu kuyiqiniso ikakhulukazi eminyakeni emisha). Futhi singabheka ukukhanya kwe-Check Engine noma inkomba eyazisa ngokungahambi kahle ohlelweni lokuhlanza igesi ephumayo. Okwesithathu, futhi okubaluleke kakhulu, akukho nesisodwa isenzo kulezi ezingenhla (ukususa, ukukhishwa, ukuphuphuthekisa) esisemthethweni. Uma ukuhlolwa komgwaqo kuveza ukuthi sishayela imoto ngaphandle kwesistimu ye-EGR (noma enepulaki) ngakho-ke asihlangabezani nezindinganiso zokukhipha umoya, sizifaka engozini. kuze kufike ku-PLN 5000... Siphinde sibe nesibopho sokususa imoto endleleni.
