I-catalysis enezindlela ezintathu.
I-catalysis enezindlela ezintathu ibhekisela ekuguqulweni kwamagesi ayingozi njenge-CO, i-HC kanye ne-NOx kusuka ekukhishweni kwemoto kube yi-carbon dioxide engenangozi, amanzi kanye ne-nitrogen ngokusebenzisa i-oxidation kanye nokunciphisa. Ingxenye yokuthwala ye-catalyst enezindlela ezintathu iyingcezu yezinto ze-ceramic ezinezimbobo, ezifakwe epayipini elikhethekile lokukhipha umoya. Ibizwa ngokuthi i-catalyst ngoba ayihlanganyeli ekusabeleni kwe-catalytic ngokwayo, kodwa imbozwe ngesembozo sezinsimbi eziyigugu njenge-platinum, i-rhodium, i-palladium kanye ne-rare earths. Yidivayisi yokuhlanza yangaphandle ebaluleke kakhulu efakwe ohlelweni lokukhipha umoya lwezimoto.
Isimiso sokusebenza se-catalytic converter enezindlela ezintathu yile: lapho i-exhaust yemoto eshisa kakhulu idlula kudivayisi yokuhlanza, i-purifier ku-catalytic converter enezindlela ezintathu izothuthukisa umsebenzi wamagesi amathathu i-CO, ama-hydrocarbon kanye ne-NOx, futhi iyikhuthaze ukuthi ibhekane nokusabela kwamakhemikhali okunciphisa i-oxidation, lapho i-CO i-oxidized ibe yigesi ye-carbon dioxide engenambala, engenabo ubuthi ekushiseni okuphezulu; Ama-hydrocarbon a-oxidized abe ngamanzi (H2O) kanye ne-carbon dioxide ekushiseni okuphezulu; i-NOx incishiswa ibe yi-nitrogen kanye ne-oxygen. Amagesi amathathu ayingozi aba amagesi angenangozi, ukuze i-exhaust yemoto ihlanzwe. Uma kuwukuthi kusekhona i-oxygen etholakalayo, isilinganiso somoya-fuel sinengqondo.
Ngenxa yokuthi uphethiloli uqukethe i-sulfur, i-phosphorus kanye ne-antiknock agent MMT iqukethe i-manganese, lezi zingxenye zamakhemikhali zizokwakha ama-chemical complexes ebusweni be-oxygen sensor kanye nangaphakathi kwe-three-way catalytic converter enegesi yokukhipha umoya ekhishwa ngemva kokusha. Ngaphezu kwalokho, ngenxa yemikhuba emibi yokushayela yomshayeli, noma ukushayela isikhathi eside emigwaqweni eminyene, injini ivame ukuba sesimweni sokusha esingaphelele, okuzokwakha ukuqongelela kwekhabhoni ku-oxygen sensor kanye ne-three-way catalytic converter. Ngaphezu kwalokho, izindawo eziningi zezwe zisebenzisa uphethiloli we-ethanol, onomphumela wokuhlanza onamandla, uzohlanza ukungcola ekamelweni lokusha kodwa awukwazi ukubola nokusha, ngakho-ke ngokukhishwa kwegesi yokukhipha umoya, lokhu kungcola kuzobekwa futhi ebusweni be-oxygen sensor kanye ne-three-way catalytic converter. Kungenxa yezici eziningi ukuthi ngemva kokuba imoto ishayelwe isikhathi esithile, ngaphezu kokuqongelela kwekhabhoni ku-valve yokungenisa kanye negumbi lokushisa, kuzophinde kubangele ukwehluleka kwe-sensor ye-oxygen kanye nokwehluleka kobuthi be-catalyst obunezindlela ezintathu, ukuvimba kwe-catalyst enezindlela ezintathu kanye ne-valve ye-EGR evinjiwe yi-sediment kanye nokunye ukwehluleka, okuholela ekusebenzeni okungajwayelekile kwenjini, okuholela ekusetshenzisweni kukaphethiloli okwandisiwe, ukwehla kwamandla kanye nokukhishwa kwegesi okungaphezu kwesilinganiso.
Ukugcinwa kwenjini okuvamile kwendabuko kunqunyelwe ekugcinweni okuyisisekelo kohlelo lokugcoba, uhlelo lokungenisa kanye nohlelo lokuphakelwa kukaphethiloli, kodwa akukwazi ukuhlangabezana nezidingo zokugcinwa eziphelele zohlelo lwesimanje lokugcoba injini, uhlelo lokungenisa, uhlelo lokuphakelwa kukaphethiloli kanye nohlelo lokukhipha uphethiloli, ikakhulukazi izidingo zokugcinwa kohlelo lokulawula ukukhishwa komoya. Ngakho-ke, noma ngabe imoto igcinwa ijwayelekile isikhathi eside, kunzima ukugwema izinkinga ezingenhla.
Ukuphendula ukwehluleka okunjalo, izinyathelo ezithathwa amabhizinisi okulungisa ngokuvamile ukufaka esikhundleni sezinzwa ze-oxygen kanye nama-catalytic converters anezindlela ezintathu, kodwa ngenxa yenkinga yezindleko zokufaka esikhundleni, izingxabano phakathi kwamabhizinisi okulungisa kanye namakhasimende ziyaqhubeka. Ikakhulukazi, lawo ma-oxygen sensor kanye nama-catalyst anezindlela ezintathu angazange athathelwe indawo isikhathi sawo sokusebenza ngokuvamile yiwona agxile ezingxabanweni, futhi amakhasimende amaningi aze athi inkinga ibangelwa yikhwalithi yemoto.
Ukuze kuxazululwe le nkinga enzima yokuxazulula inkinga yamabhizinisi okukhiqiza izimoto, amabhizinisi okulungisa, iminyango yokuphatha ukugcinwa kanye neminyango yokuvikela imvelo, izikhungo zocwaningo lwesayensi ezifanele zicwaninge futhi zaklama isethi entsha yezindlela nobuchwepheshe bokulungisa injini ukuze kutholakale amaphutha ezindlela zokulungisa injini zendabuko.
Okuqukethwe kwalobu buchwepheshe obusha yilokhu: lapho kwenziwa ukulungiswa okuvamile kwamakhasimende, ngaphezu kokushintsha uwoyela nokugcinwa kwezihlungi ezintathu, kufakwe ukuhlanza nokugcinwa kwe-catalytic converter enezindlela ezintathu. Izici zayo zobuchwepheshe yilezi: Inhlanganisela ye-organic "yokuhlolwa kwezinto zokulawula igesi yokukhipha imoto" kanye nezindlela zokulungisa ezivamile zenjini ukuze kulungiswe izindlela zendabuko zokulungisa ezivamile zenjini azikwazi ukuhlangabezana nezidingo zeziphambeko zesimanje zokulungisa injini, Isixazululo esingenzi lutho senkinga yokusebenza okungavamile kohlelo lokulawula ukukhishwa kwenjini yokuvikela imvelo sizoshintshwa sibe ukuvimbela okusebenzayo kokusebenza okungavamile kohlelo lokulawula ukukhishwa kwenjini yokuvikela imvelo.
1, uma kukhona umonakalo womshini, ukushisa okushisayo, ibanga elingaphezu kwamakhilomitha angu-200,000, ubuthi be-lead, umphumela wokuhlanza awukhulu.
2, njengenjini phakathi nokuhlanza, nqamula ngokushesha ipayipi lokuxhuma injini nemishini, bese uvala ivalvu yokugeleza. Qala kabusha injini, ingavimbeki, ingaxhunywa kabusha futhi ilungiswe.
3, hlola ukuthi ukuhlushwa kwengxube kufaneleka yini ukuqinisekisa ukuthi uketshezi lungaphefumulwa endaweni yokungena yenkungu.
