Kuyini ukulawula i-turbocharger yezimoto
Indlela yokulawula i-turbocharger yemoto isetshenziswa kakhulu uhlelo lokulawula ingcindezi ye-turbocharger elawulwa ngogesi. Uhlelo lwakhiwe nge-valve ye-solenoid yokukhulula ingcindezi, i-actuator ye-pneumatic, i-valve ye-bypass kanye ne-supercharger. Ukulawulwa kwengcindezi ye-booster yesistimu kutholakala ngokuvula nokuvala i-valve ye-bypass: lapho i-bypass valve ivaliwe, cishe yonke igesi yokukhipha igesi igeleza nge-booster, futhi ingcindezi ye-booster iyakhuphuka; Lapho i-bypass valve ivulwa, ingxenye yegesi yokukhipha igesi ikhishwa ngqo ngesiteshi se-bypass, futhi ingcindezi ye-booster iyancipha.
Ukuvulwa nokuvalwa kwevalvu ye-bypass kufezwa yi-ECU (i-Electronic control Unit) ngokulawula ivalvu ye-solenoid yokukhulula ingcindezi kanye ne-pneumatic actuator . I-ECU ilawula ingcindezi yokukhulisa ngokwengcindezi ye-input manifold, kanti ivalvu ye-bypass ivulwa ngesivinini esikhulu kanye nomthwalo omkhulu ukuze kugwenywe umthwalo oweqile wemishini nokushisa wenjini ngesivinini esikhulu. Ngaphezu kwalokho, amanye amamodeli asebenzisa nohlelo lokulawula oluvaliwe, ngokusebenzisa inzwa yesikhundla ukuze anikeze imiphumela yokusebenza yangempela ku-ECU, alungise ngokwendlela yokuphambuka, ukuze alawule ngokunembile i-torque yenjini .
Umgomo osebenzayo we-turbocharger ukushayela i-turbine ngegesi yokukhipha ekhishwa yinjini, bese ucindezela umoya wokungenisa ukuze kuthuthukiswe ubuningi bomoya, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokushisa kanye namandla okukhipha. I-Turbocharger isebenzisa i-inertia impulse yegesi yokukhipha ekhishwa yinjini ukuze icindezele i-turbine ekamelweni le-turbine, iqhube i-coaxial impeller ukuze icindezele umoya ungene kwisilinda, ikhuphule ingcindezi kanye nobuningi bomoya, futhi ngaleyo ndlela ikhuphule amandla okukhipha enjini.
Imisebenzi eyinhloko yama-turbocharger ezimoto ifaka phakathi izici ezilandelayo:
Khulisa amandla enjini kanye ne-torque: Ama-turbocharger andisa inani lomoya ongena kwisilinda, okwenza injini ikwazi ukufaka uphethiloli omningi ngesikhathi esifanayo, ngaleyo ndlela ikhulisa amandla enjini kanye ne-torque. Ngokuvamile, ama-turbocharger angandisa amandla aphezulu enjini ngo-20% kuya ku-40%, kanye ne-torque ephezulu ngo-30% kuya ku-50%.
Nciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi: Ama-Turbocharger anciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi ngokuthuthukisa ukusebenza kahle kokushisa kwenjini kanye nokuthuthukisa ukusebenza kahle kokushisa. Ngokukhethekile, i-turbocharger inganciphisa ukusetshenziswa kukaphethiloli kwenjini ngo-5% kuya ku-10%, kanti ukukhishwa kwamagesi ayingozi njenge-CO, i-HC kanye ne-NOx nakho kuncishiswe ngokufanayo.
Ukonga uphethiloli okuthuthukisiwe: Izinjini ezine-turbocharger zishisa kangcono, zonga u-3% kuya ku-5% kaphethiloli. Ngaphezu kwalokho, ama-turbocharger athuthukisa izici zokufanisa injini kanye nezici zokuphendula zesikhashana ukuze konga uphethiloli okuthuthukisiwe.
Thuthukisa ukuzivumelanisa nezimo kwenjini kanye nokuthembeka kwayo: I-Turbocharger ingenza injini ibe semazingeni aphezulu ahlukene, amazinga okushisa kanye nezimo zomthwalo ukuze igcine ukusebenza okungcono kanye nokuqina, ukugwema amandla angaphansi kwenjini, ukungqongqoza, ukushisa ngokweqile kanye nezinye izinkinga. Ngesikhathi esifanayo, ama-turbocharger angandisa nokuphila kwenjini futhi anciphise izinga lokwehluleka.
Umsebenzi wokunciphisa i-plateau: endaweni ye-plateau, ngenxa yomoya omncane, ukusebenza kwezinjini ezijwayelekile kuzothinteka futhi amandla azoncishiswa. I-turbocharger ingakwazi ukuvala ngempumelelo ukulahlekelwa kwamandla okubangelwa umoya omncane ngokwandisa ubuningi bokungenisa.
