I-catalysis yezindlela ezintathu.
I-Tree-way catalysis ibhekisela ekuguqulweni kwamagesi ayingozi afana ne-CO, i-HC ne-NOx kusukela ekukhishweni kwemoto ibe yi-carbon dioxide engenabungozi, amanzi ne-nitrogen ngokusebenzisa i-oxidation nokunciphisa. Ingxenye yenkampani ye-catalyst yezindlela ezintathu iyingcezu ye-porous ceramic material, efakwe kwipayipi ekhethekile yokukhipha. Ibizwa ngokuthi umthwali ngoba ayihlanganyeli ekuphenduleni kwe-catalytic ngokwayo, kodwa imbozwe ngendwangu yezinsimbi eziyigugu njenge-platinum, i-rhodium, i-palladium kanye nomhlaba ongavamile. Kuyidivayisi ebaluleke kakhulu yokuhlanza yangaphandle efakwe ohlelweni lokukhipha umoya wezimoto.
Isimiso sokusebenza sesiguquli se-catalytic sezindlela ezintathu sithi: uma umoya wezimoto onezinga lokushisa eliphezulu udlula kudivayisi yokuhlanza, isihlanzi esiguquli sendlela ezintathu sizothuthukisa umsebenzi wamagesi amathathu CO, ama-hydrocarbon kanye ne-NOx, futhi sikhuthaze. ukuze ibhekane nokusabela okuthile kwamakhemikhali okunciphisa i-oxidation, lapho i-CO ifakwe i-CO oxid yaba igesi ye-carbon dioxide engenambala engenabuthi ezingeni lokushisa eliphezulu; Ama-hydrocarbon afakwa emanzini (H2O) kanye ne-carbon dioxide emazingeni okushisa aphezulu; I-NOx yehliselwa ku-nitrogen nomoya-mpilo. Amagesi amathathu ayingozi aba amagesi angenabungozi, ukuze isisi sezimoto sihlanzeke. Uma sicabanga ukuthi kusekhona umoya-mpilo otholakalayo, isilinganiso sikaphethiloli womoya sinengqondo.
Ngenxa yokuthi uphethiloli uqukethe isulfure, i-phosphorus kanye ne-ejenti ye-antiknock ye-MMT iqukethe i-manganese, lezi zingxenye zamakhemikhali zizokwakha ama-chemical complexes endaweni yenzwa yomoya-mpilo nangaphakathi kwesiguquli se-catalytic yezindlela ezintathu ngegesi yokukhipha umoya ekhishwa ngemva kokusha. Ngaphezu kwalokho, ngenxa yemikhuba emibi yokushayela yomshayeli, noma ukushayela isikhathi eside emigwaqweni eminyene, injini ivamise ukuba sesimweni sokusha esingaphelele, okuzokwenza ukunqwabelana kwekhabhoni kusizwa komoyampilo kanye nesiguquli se-catalytic sendlela ezintathu. Ngaphezu kwalokho, izindawo eziningi zezwe zisebenzisa uphethiloli we-ethanol, onomphumela oqinile wokuhlanza, uzohlanza ukungcola ekamelweni elivuthayo kodwa awukwazi ukubola nokushisa, ngakho-ke ngokuphuma kwegesi yokukhipha, lokhu kungcola kuzophinde kufakwe endaweni yokushisa. indawo engaphezulu yenzwa ye-oxygen kanye nesiguquli se-catalytic sezindlela ezintathu. Kungenxa yezici eziningi ukuthi ngemva kokuba imoto ishayelwa isikhathi esithile, ngaphezu kokunqwabelana kwekhabhoni ku-valve yokungenisa kanye negumbi elivuthayo, kuzophinde kubangele inzwa ye-oxygen kanye nokwehluleka kobuthi bezindlela ezintathu, lezi ezintathu. -indlela yokuvinjwa kwe-catalyst kanye ne-valve ye-EGR ivinjwe yi-sediment nokunye ukwehluleka, okuholela ekusebenzeni okungavamile kwenjini, okuholela ekwenyukeni kokusetshenziswa kukaphethiloli, ukwehla kwamandla kanye nokukhipha amandla okudlula izinga.
Ukunakekelwa kwenjini okuvamile kukhawulelwe ekunakekeleni okuyisisekelo kwesistimu yokuthambisa, isistimu yokuthatha kanye nesistimu yokuphakela uphethiloli, kodwa ayikwazi ukuhlangabezana nezidingo eziphelele zokulungiswa kwesistimu yesimanje yokuthambisa injini, isistimu yokuthatha, isistimu yokuphakela uphethiloli kanye nesistimu yokukhipha umoya, ikakhulukazi izidingo zokunakekela. yesistimu yokulawula ukungcola. Ngakho-ke, ngisho noma imoto igcinwa ngokujwayelekile isikhathi eside, kunzima ukugwema izinkinga ezingenhla.
Ekuphenduleni ukwehluleka okunjalo, izinyathelo ezithathwa amabhizinisi okunakekela ngokuvamile ziwukuba esikhundleni sezinzwa ze-oxygen kanye neziguquli ze-catalytic zezindlela ezintathu, kodwa ngenxa yenkinga yezindleko zokushintshwa, izingxabano phakathi kwamabhizinisi okunakekela kanye namakhasimende ziyaqhubeka. Ikakhulukazi, lezo zinzwa ze-oksijini kanye nama-catalysts wezindlela ezintathu ezingazange zithathelwe indawo impilo yazo ewusizo zivame ukugxila ezingxabano, futhi amakhasimende amaningi aze athi inkinga yikhwalithi yemoto.
Ukuze kuxazululwe leli khanda elibuhlungu futhi kube nzima ukuxazulula inkinga yamabhizinisi okukhiqiza izimoto, amabhizinisi okunakekela, iminyango yokuphatha ukugcinwa kwemvelo kanye neminyango yokuvikela imvelo, izikhungo zocwaningo lwesayensi ezifanele ziye zacwaninga futhi zaklama isethi entsha yezindlela zokunakekela injini kanye nobuchwepheshe bokukhubazeka izindlela zendabuko zokulungisa injini.
Okuqukethwe kwalobu buchwepheshe obusha yilokhu: lapho kwenziwa ukunakekelwa okuvamile kwamakhasimende, ngaphezu kokufaka uwoyela kanye nokugcinwa kwezihlungi ezintathu, ukuhlanzwa nokugcinwa kwesiguquli se-catalytic sendlela ezintathu siyengezwa. Izici zayo zobuchwepheshe yilezi: Inhlanganisela ye-Organic "Yokuhlolwa kwesistimu yokulawula igesi yokukhipha igesi kanye nezinto zokulungiswa" kanye nezindlela zendabuko zokulungisa injini ezijwayelekile zokwenza izindlela zokulungisa ezijwayelekile zenjini azikwazi ukuhlangabezana nezidingo zokukhubazeka kokulungiswa kwenjini yesimanje, Isixazululo se-passive to inkinga yokusebenza okungavamile kohlelo lokulawula ukungcola kwenjini yokuvikela imvelo izoshintshwa ibe ukuvimbela okusebenzayo kokusebenza okungavamile kohlelo lokulawula ukungcola kwenjini yokuvikela imvelo.
1, uma kunomonakalo wemishini, ukushisa okushisayo, imayela elingaphezu kwamakhilomitha angama-200,000, ubuthi bomthofu, umphumela wokuhlanza awumkhulu.
2, njengenjini ephakathi nendawo yokuhlanza, nqamula ngokushesha ipayipi lokuxhuma injini nemishini, bese uvala i-valve yokugeleza. Qalisa kabusha injini, ayinyakazi, ingaxhunywa futhi futhi ilungiswe.
3, hlola ukuthi ingxube ifanelekile yini ukuze uqinisekise ukuthi uketshezi lungadonswa endaweni yokufaka inkungu.
I-4, ukuhlanza izingxenye ezintathu kufanele kuhlanzwe ngemuva kwe-throttle, i-fuel nozzle kanye negumbi lomlilo.
5, phakathi nenqubo yokuhlanza, isivinini sokungenzi lutho akufanele sibe phezulu kakhulu ukugwema ukushisisa ngokweqile kwesiguquli se-catalytic esinezindlela ezintathu.
6, ungawehli uketshezi lokuhlanza kupende wemoto.
7, indawo yokusebenza kude nomthombo womlilo, yenza umsebenzi omuhle wezinyathelo zomlilo.
