Iyini i-Automotive turbocharger control
Indlela yokulawula ye-automobile turbocharger ibonakala ikakhulukazi ngohlelo lokulawula ukucindezela kwegesi ephumayo elawulwa nge-electronic turbocharger. Uhlelo lwakhiwe i-valve yokusiza i-solenoid yokucindezela, i-actuator yomoya, i-bypass valve kanye ne-supercharger. Ukulawulwa kwengcindezi ye-booster yesistimu kubonakala ngokuvula nokuvalwa kwe-valve ye-bypass: lapho i-valve ye-bypass ivaliwe, cishe yonke igesi yokukhipha igeleza nge-booster, futhi ingcindezi ye-booster iyanda; Lapho i-valve ye-bypass ivuliwe, ingxenye yegesi yokukhipha igesi ikhishwa ngokuqondile ngesiteshi se-bypass, futhi umfutho we-booster uyancipha.
Ukuvulwa nokuvalwa kwe-valve ye-bypass kufinyelelwa yi-ECU (Iyunithi yokulawula ye-elekthronikhi) ngokulawula i-valve ye-solenoid yokunciphisa ukucindezela kanye ne-actuator yomoya. I-ECU ilawula umfutho we-boost ngokuya ngengcindezi ye-manifold yokuthatha, futhi i-valve ye-bypass ivulwa ngesivinini esikhulu nomthwalo omkhulu ukugwema umthwalo oweqile wemishini nokushisa wenjini ngesivinini esikhulu. Ngaphezu kwalokho, amanye amamodeli aphinde asebenzise isistimu yokulawula iluphu evaliwe, ngokusebenzisa inzwa yesikhundla ukondla imiphumela yangempela yokubulawa ku-ECU, ulungise ngokuya ngokuphambuka, ukuze ulawule ngokunembe kakhudlwana i-torque yenjini.
Isimiso sokusebenza se-turbocharger ukushayela i-turbine ngegesi yokukhipha injini ekhishwa yinjini, bese ucindezela umoya owuthathayo ukuze uthuthukise ukuminyana komoya, ngaleyo ndlela kuthuthukiswe ukusebenza kahle komlilo namandla okukhipha. I-Turbocharger isebenzisa umfutho we-inertia wegesi yokukhipha umoya ekhishwa injini ukuze iphushe i-turbine egumbini le-turbine, ishayela isixhumi se-coaxial ukuze sicindezele umoya kusilinda, ikhuphule umfutho kanye nokuminyana komoya, futhi ngaleyo ndlela ikhulise amandla okukhipha enjini.
Imisebenzi esemqoka yama-turbocharger ezimoto ihlanganisa lezi zici ezilandelayo:
Khulisa amandla enjini kanye ne-torque : Ama-Turbocharger anyusa inani lomoya ongena kusilinda, okwenza injini ikwazi ukujova uphethiloli owengeziwe endaweni efanayo, ngaleyo ndlela andise amandla enjini kanye netorque. Ngokuvamile, ama-turbocharger angakhuphula amandla amakhulu enjini ngo-20% kuya ku-40%, kanye ne-torque ephezulu ngo-30% kuya ku-50%.
Nciphisa ukusetshenziswa kukaphethiloli kanye nokukhipha umoya : Ama-Turbocharger anciphisa ukusetshenziswa kukaphethiloli kanye nokukhipha umoya ngokuthuthukisa amandla omlilo enjini kanye nokwenza ngcono ukusebenza kahle kokushisa. Ngokukhethekile, i-turbocharger inganciphisa ukusetshenziswa kukaphethiloli kwenjini ngo-5% kuya ku-10%, futhi ukukhishwa kwamagesi ayingozi njenge-CO, HC ne-NOx nakho kuyehliswa ngokufanayo.
Ukonga uphethiloli okuthuthukisiwe : Izinjini ezinama-turbocharger zivutha kangcono, zonga u-3% kuya ku-5% kaphethiloli. Ngaphezu kwalokho, ama-turbocharger athuthukisa izici zokufanisa injini nezici zokuphendula zesikhashana ukuze kuthuthukiswe ukonga kukaphethiloli.
Thuthukisa ukuguquguquka kwenjini nokuthembeka : I-Turbocharger ingenza injini ibe ezindaweni eziphakeme ezihlukene, amazinga okushisa nezimo zokulayisha ukuze igcine ukusebenza okungcono nokuzinza, ukugwema amandla enjini angaphansi, ukushaya, ukushisa ngokweqile nezinye izinkinga. Ngesikhathi esifanayo, ama-turbocharger anganweba futhi impilo yenjini futhi ehlise izinga lokuhluleka.
umsebenzi wesinxephezelo sethafa : endaweni yethafa, ngenxa yomoya omncane, ukusebenza kwezinjini ezijwayelekile kuzothinteka futhi amandla azoncishiswa. I-turbocharger ingavala ngempumelelo ukulahleka kwamandla okubangelwa umoya omncane ngokukhuphula ukuminyana kokuthatha.
