Ukuphelelwa amandla ngemva kokukhipha i-catalyst - kungaba yini izizathu

Ingxenye ye-exhaust line ayinzima ukuyisika: ungayenza ngokwakho noma ezinsizeni zezimoto. E-Russia, isenzo esinjalo asithathwa njengesingekho emthethweni uma kufakwe iqembu elilodwa kuphela lama-lambda probes emotweni. Kodwa ngisho nesethi egcwele yezinzwa ze-oxygen, abahloli bezimoto ababonisi isithakazelo esengeziwe ku-catalyst.

Amagesi e-exhaust ayasha kusiguquli se-catalytic semoto. Ingxenye ebhekele ukuhlanzeka kwezisi ezingcolisa umoya emoyeni isuswa abashayeli abaningi. Amandla enjini kaphethiloli yangaphakathi (ICE) akhula ngokushesha, ukusetshenziswa kukaphethiloli kuyancipha. Kodwa lapha kuphakama inkinga. Umshayeli uyaqaphela: ngokushesha nje lapho i-catalyst isusiwe, kwavela intuthu epayipini lokukhipha umoya. Iyini imbangela yalesi simo, nendlela yokubuyisela uhlelo lokukhipha umoya esimweni esivamile - isihloko sengxoxo ezinkundleni zomshayeli.

Kungani imoto ibhema kakhulu ngemva kokukhipha ama-catalysts

I-Converter-neutralizer (i-catalyst, CT, "kat"), etholakala phakathi kwe-motor ne-muffler, yenziwa ngendlela yepayipi yensimbi enezinyosi ze-ceramic ngaphakathi. Lezi zokugcina zimbozwe ngezinsimbi ezihloniphekile (kaningi - i-platinum), okubangela izindleko eziphakeme zamakati.

Ukubhema ngemva kokususwa kwama-catalysts

Isici sifakwe phakathi kwamaqembu okuqala nesesibili sezinzwa ze-oxygen (i-lambda probes), elawula imingcele yamagesi okukhipha umoya: izinga lokushisa, okuqukethwe kokungcola okuyingozi. Amakhekheba oju adala ukumelana nokugeleza kwe-exhaust, ehlisa isivinini sawo. Ngalesi sikhathi, lapho kufafazwa kwamakhekheba ezinyosi, ukushiswa kwamagesi aphuma kumasilinda enjini kwenzeka. Njengomphumela wokusabela kwamakhemikhali (i-catalysis), ubuthi bezinto ezikhishwa ngaphandle buyancipha.

I-fuel afterburning system ibizwa nge-EGR, futhi ukufakwa kwayo ku-exhaust tract kudingwa yizinkambiso nezindinganiso zanamuhla - Euro 1-5.

Ngemuva kokukhipha i-CT ohlelweni lokukhipha umoya, okulandelayo kwenzeka:

• Kulindelwe inani elikhulu legesi, ngakho-ke intuthu enemibala enamandla iphuma ku-muffler.
• Injini ye-ECU, edidwe ulwazi oluhlanekezelwe oluvela kuzinzwa, inika umyalo wokucebisa noma ukuncika ingxube yesibaseli somoya wamasilinda enjini. Okubuye kuhambisane nentuthu.
• I-backpressure ekuhlanganiseni kwe-exhaust iyashintsha. Incishiswa ukwanda kokusetshenziswa kukawoyela. Ngakho-ke, isakhiwo sokuqeda siyahluka, futhi umshayeli ubona i-plum ngemuva kwemoto.

Uma ukubukeka kwentuthu kuthole ukulungisiswa okunengqondo, khona-ke umbala udinga ukubhekwana nawo ngokwehlukana.

Izinhlobonhlobo zentuthu ezivela epayipini lokukhipha umoya

Ngemuva kokukhipha i-kata, kuyadingeka ukulungisa "ubuchopho" bomshini - ukukhanyisa kabusha ikhompyutha. Uma ungenjalo, lindela "umsila" ngemibala elandelayo:

• Intuthu emnyama ikhombisa ukuthi le ngxube inothe kakhulu ngophethiloli, ongena kumasilinda. Njengoba ingenaso isikhathi sokushiswa, ingxenye yamafutha iphonswa emgqeni wokukhipha umoya. Lapha iphutha likuyunithi yokulawula injini ye-elekthronikhi. Ngemuva kokwenza i-firmware yekhwalithi ephezulu, uzosusa inkinga.
• Umbala oluhlaza okwesibhakabhaka noma ompunga-oluhlaza okwesibhakabhaka we-exhaust ubonisa amafutha amaningi epheshaneni. Inani eliningi le-lubricant livela ngenxa yokwanda kwengcindezi emuva ngemva kokususwa kwe-catalyst. Isixazululo senkinga ukufaka isibambisi somlilo esikhundleni sesici esinqunyiwe.
• Intuthu emhlophe evela epayipini lokukhipha umoya ngemva kokukhipha i-catalyst ivela ekungeneni kwesipholile ohlelweni. Nakuba i-CT ingase ingahlanganise lutho nayo: mhlawumbe iwukukhuphuka kwe-condensate.

Ukuze unqume ngokunembe kakhudlwana imbangela yomusi, udinga ukuqaphela ukuthi isiphi isivinini nesivinini okwenzeka ngaso: lapho uphinda futhi usheshisa imoto, ngokungenzi lutho.

Okufanele ukwenze uma imoto ibhema ngemva kokukhipha i-catalyst

Ingxenye ye-exhaust line ayinzima ukuyisika: ungayenza ngokwakho noma ezinsizeni zezimoto. AT

E-Russia, isenzo esinjalo asithathwa njengesingekho emthethweni uma kufakwe iqembu elilodwa kuphela lama-lambda probes emotweni.

Kodwa ngisho nesethi egcwele yezinzwa ze-oxygen, abahloli bezimoto ababonisi isithakazelo esengeziwe ku-catalyst.

Qeda intuthu

Kodwa-ke, udinga ukuqonda ukuthi ukususwa kwe-kata kuwukuphazamiseka okukhulu ekwakhiweni kwemoto. Lokhu kuhlanganisa ukubonakala kwezinkinga: intuthu yamathunzi ahlukene, iphunga elinamandla nemisindo engaphandle ngaphansi.

Ngemva kokususa into, thatha izinyathelo ezilandelayo:

1. Faka isivimbeli somlilo noma esinamandla esikhundleni se-neutralizer, engabizi kakhulu kune-catalyst. Lokhu kusebenza ezimweni lapho ukususwa kwengxenye kwakuyisilinganiso esidingekayo (isibonelo, ngemva kokuhlukana).
2. Lungiselela kabusha, noma kunalokho, khubaza, ama-lambda probe. Uma kungenjalo, iphutha le-Check Engine lizoba kuphaneli yezinsimbi, njengoba injini ihlale isebenza kumodi yesimo esiphuthumayo.
3. Lungisa uhlelo lwe-ECU lwenjini, layisha i-firmware entsha.

Izinzuzo zokunqamula i-catalyst zincane, kanti izinkinga zibaluleke kakhulu.
