Ukuhlola isimo sobuchwepheshe semoto ethengiwe, sivame ukukhohlwa ukuhlola ukusebenza kwe-catalytic converter. Khonamanjalo, kukhona abathengisi abaningi abangathembekile abahlinzeka ngezimoto ezineziguquli ezilimele noma ezingenazo i-catalytic.

Ukuhlola isimo sobuchwepheshe semoto ethengiwe, sivame ukukhohlwa ukuhlola ukusebenza kwe-catalytic converter. Khonamanjalo, kukhona abathengisi abaningi abangathembekile abahlinzeka ngezimoto ezineziguquli ezilimele noma ezingenazo i-catalytic. Uma ngesikhathi sokuhlolwa kwezobuchwepheshe kwemoto kuvela ukuthi le mishini inephutha, imoto ngeke ivunyelwe ukusebenza.

Akukho ukuxilonga okuphelele kwesimo se-catalyst kungenzeka ngokwethu, kufanele sisizakale ngomakhenika abaqeqeshiwe. Isithombe ngu-Robert Quiatek

I-catalyst iyimishini yemoto, okunzima ukuyihlola ngokwakho. Idivayisi ngokwayo inzima ukuyibona, itholakala ngaphansi kwemoto, ngokuvamile ifihliwe ngemuva komzimba. Kodwa-ke, lapho uthenga imoto esetshenzisiwe, kufanelekile ukuthatha isikhathi sokuhlola lesi sici semoto, njengoba ngokuvamile kubiza kakhulu ukulungisa. Isinyathelo sokuqala kungaba ukuhlola ukuthi isiguquli se-catalytic sifakiwe ngempela yini emotweni. Nokho, kufanele ungene esiteshini ukuze wenze njalo. Kwenzeka ukuthi kwezinye izimoto kufakwe ucezu lwethubhu esikhundleni se-catalytic converter. Awudingi ukuba umakhenikha onolwazi ukuze ubone "ukuguqulwa" okunjalo shazi. Yiqiniso, ukungabi khona kwe-catalyst akubandakanyi ithuba lokuhlangana kwayo okulandelayo, kodwa kuzodingeka sicabangele izindleko, ngokuvamile ezisukela kumakhulu ambalwa kuya kwezingu-2 zł.

Bheka isimo se-catalytic converter!

Ukulawula okuwusizo

Umonakalo we-Catalyst utholakala kalula kakhulu ngokulinganisa izinga lobuthi be-exhaust, kuchaza u-Wojciech Kulesza, umhloli we-PZMot onelayisensi. - Izimpawu zokungasebenzi kwayo ngokuvamile zibonakala ngesikhathi sokusebenza kwemoto. Ukuphelelwa amandla, umsindo omkhulu wenjini, noma izinkinga zokuqalisa kungaba izimpawu zokuthi isiguquli se-catalytic asisebenzi ngokugcwele.

Ukuze usebenze kahle, ukwakheka okuchazwe ngokuqinile kwengxube ye-fuel-air kuyadingeka. Isilinganiso esiphezulu somoya kuphethiloli ngu-14,75:1. Imishini yomjovo elawulwa ikhompuyutha kuphela enganikeza imithamo elinganiswe ngokunembile yengxube, ngakho-ke ama-catalysts afaneleka kangcono izimoto ezifakwe umjovo kaphethiloli kune-carburetor. Umsebenzi obalulekile wenziwa futhi i-lambda probe etholakala kusistimu yokukhipha umoya ngemuva kwe-catalyst. Ihlaziya ukwakheka kwamagesi aphumayo futhi ithumele amasignali kukhompuyutha yokulawula umjovo. Uma isiguquli se-catalytic sonakele, kunzima ukukubona ngeso lenyama. Nokho, ukulawulwa kwamagesi e-exhaust aphuma epayipini lokukhipha umoya kuzositshela okuningi. Isici esibaluleke kakhulu iphesenti le-carbon monoxide (CO) kumagesi aphumayo. Emotweni engenawo i-catalytic converter noma ene-catalyst eyonakele, isukela ku-1,5 kuya ku-4%. I-catalyst esebenzayo inciphisa lesi silinganiso siye cishe ku-0,03% noma sibe ngaphansi kancane.

Okuqukethwe kwezinye izinhlanganisela (ama-nitrogen oxides, ama-hydrocarbon kanye ne-carbon dioxide) kuwumphumela wenani le-CO. Ukuhlola okwenziwa esiteshini sokuxilonga kuzoveza noma yikuphi ukungahambi kahle okuvela, futhi iso eliqeqeshiwe likamakhenikha lizobona noma yimuphi umonakalo owenziwe yimishini.

“Uma uthenga imoto eke yasetshenziswa, kuyafaneleka futhi ukubuza umdayisi ukuthi imishini ike yashintshwa yini ngaphambilini,” kusho uWojciech Kulesza, umhloli we-PZMot onelayisensi. - Ama-catalysts anamuhla ahlala isikhathi eside, kodwa abakhiqizi abaningi batusa ukushintshwa ngemuva kwamakhilomitha ayizinkulungwane ezingu-120-150. Yiqiniso, ama-catalysts angahlala amakhilomitha angu-250 ngaphandle kokulimala, kodwa lapho unquma ukuthenga imoto ene-mileage ephezulu kumitha, kufanele acabangele ukuthi i-catalyst ingase idinge ukushintshwa ngenxa yokuguga.

Imithetho ebalulekile

Qaphela uphethiloli - ngisho nenani elincane likaphethiloli omthofu lingabhubhisa unomphela isiguquli se-catalytic. Kulula ukwenza iphutha, ikakhulukazi uma ufaka uphethiloli ku-canister.

Ungazami ukuqalisa imoto usebenzisa "ukuziqhenya" indlela.

Zama ukusebenzisa iziteshi zikaphethiloli eziqinisekisiwe lapho izinga likaphethiloli lihle. Uphethiloli ongcolile futhi wekhwalithi ephansi uholela ekuncibilikeni kwe-catalytic liner ngenxa yokushisa okuphezulu kokusebenza. Izinga lokushisa elilungile lokusebenza kwe-catalyst lilinganiselwa ku-600°C, ngophethiloli ongcolile lingafinyelela ku-900°C.

Hlola isimo se-spark plug njalo. Ukungabi bikho kwenhlansi kwelinye lamasilinda kuholela kuphethiloli ongashisiwe ongena exhaust system, ungcolise i-catalyst.

Ingalimala uma ishaya itshe, unqenqema, njll.

Akwenzeki ukupholisa ngokushesha i-catalyst, okwenzeka, isibonelo, lapho ushayela echibini elijulile.

Hlola ngaphambi kokuthenga

Wojciech Kulesza, onelayisensi ye-PZMot appraiser

- Ngaphambi kokuthenga imoto esetshenzisiwe, kufanelekile ukuhlola ukuthi ipayipi lokukhipha umoya libukeka kanjani. Uma inothuli kakhulu noma imbozwe insipho, lokhu kuwuphawu oluqinisekile lokuthi isistimu yokukhipha umoya, ikakhulukazi i-catalytic converter, ingase yehluleke. Kulula futhi ukuhlola ukuthi isiguquli se-catalytic sishintshiwe muva nje, kodwa lokhu kuvame ukudinga ukuthi imoto ingene esiteshini. Imishini emisha izodonsa amehlo ngokubukeka kwayo okusha kanye neshidi lensimbi elicwebezelayo, ngakho kulula ukuqhathanisa iziqinisekiso zomthengisi neqiniso. Sizophinde sihlole i-catalyst ukuthola izimpawu zokulimala kwemishini. Noma yikuphi ukuqhekeka noma ukugoba kungase kubonise ukuthi ishayiwe, futhi ukufakwa kwayo kobumba kungase kuqhekeke.
