Ama-injector kaphethiloli - "Imimoya Kaphethiloli" Yenjini
Ohlelweni oluyinkimbinkimbi lwenjini yemoto, i-fuel injector idlala indima ebalulekile "njengomoya kaphethiloli", njengenye yezingxenye eziyinhloko zezinjini zokujova uphethiloli kagesi. Empeleni, iyi-valve elula ye-electromagnetic. Lapho i-coil ye-electromagnetic inikwe amandla, amandla okumunca akhiqizwayo azophakamisa i-valve yenaliti, avule i-nozzle, bese uphethiloli ufuthwa ngesivinini esikhulu ngesikhala esiphakathi kwekhanda lenaliti ne-nozzle, kwakha isimo esifana ne-mist, esibe sesixubana nomoya ukuze kufezwe izimo zokusha ezinhle kakhulu zenjini.
Ukunemba kokusebenza kwe-fuel injector kunquma ngqo ukusebenza kwenjini. Ngaphansi kwemiyalelo eqondile yeyunithi yokulawula kagesi yenjini (i-ECU), ifutha uphethiloli kusilinda ngezikhathi ezijwayelekile nangobuningi obuhleliwe ngokwesimo sokusebenza kwenjini. Kunezinhlobo ezimbili ngokuyinhloko zezindlela zokufutha uphethiloli: eyodwa iwukujova kwe-incase manifold, lapho i-fuel injector itholakala ku-incase manifold bese ifutha uphethiloli ku-incase manifold ukuze ixubane nomoya ngaphambi kokungena kusilinda; enye iwukujova ngqo kusilinda, lapho i-fuel injector ingena ngqo ngaphakathi kwesilinda bese ifutha uphethiloli ngokucindezela okuphezulu kusilinda. Nakuba lezi zindlela ezimbili zinezimiso ezifanayo zesakhiwo, i-direct injection fuel injector idinga ukumelana nokucindezela okuphezulu, ngokuvamile kusuka kumakhilogremu angu-24 kuya kwangu-200, kuyilapho ingcindezi ye-incase manifold injection ngokuvamile iphakathi kwamakhilogremu angu-2 no-8.
Ukujova uphethiloli ngendlela enembile kuyisiqinisekiso sokusebenza kahle kwenjini. I-fuel injector ilawula ivolumu yokujova uphethiloli kanye nesikhathi ukuqinisekisa ukuthi injini ingathola isilinganiso esifanele somoya-uphethiloli ngaphansi kwezimo zokusebenza ezahlukene, ngaleyo ndlela ifinyelele ibhalansi engcono kakhulu yokuphuma kwamandla, ukonga uphethiloli, kanye nokukhishwa komoya. Kungashiwo ukuthi isimo sokusebenza se-fuel injector sithinta ngqo ukusebenza kwamandla enjini, izinga lokusetshenziswa kukaphethiloli, kanye nekhwalithi yokuphuma komoya.
Ukwehluleka kwe-injector kaphethiloli - "Umbulali ongabonakali" wenjini
Njengoba ibanga lemoto likhula futhi indawo yokusetshenziswa ishintsha, ama-fuel injector nawo angabhekana nokwehluleka okuhlukahlukene, abe "umbulali ongabonakali" othinta ukusebenza kwenjini. Izimbangela zokwehluleka kwe-fuel injector ziyinkimbinkimbi futhi zihlobene kakhulu nekhwalithi kaphethiloli, imikhuba yokusebenzisa, kanye nokuguga kwezingxenye. Izinsini, ukungcola kuphethiloli, kanye nothuli olulethwa ngesikhathi sokugcina nokuthuthwa kuzoqongelela ngokuhamba kwesikhathi endaweni ye-fuel injector, kwakha ama-deposit. Lawa ma-deposit, uma eshiswa, azophenduka ama-hard carbon deposit, avimbe i-valve yenaliti kanye nezimbobo zama-valve ze-fuel injector. Ngaphezu kwalokho, ukuminyana kwezimoto zasemadolobheni kuvame ukubangela izimoto ukuthi zisebenze ngesivinini esiphansi futhi zingasebenzi, okuzophinde kusheshise ukwakheka nokuqongelela kwama-deposit.
Ukwehluleka kwe-fuel injector kuzobangela uchungechunge lwezimpawu ezisobala, kuxwayise i-车主 ukuthi inake. Uphawu lokuqala ukwehla kwamandla kanye nobunzima bokusheshisa. Lapho i-fuel injector ivalekile futhi ivolumu yokujova uphethiloli inganele, injini ayikwazi ukuthola uphethiloli owanele, futhi amandla azoncishiswa kakhulu ngokwemvelo, ikakhulukazi uma isheshisa ngokushesha, kuzokwenzeka ukubambezeleka okubonakalayo. Uphawu lwesibili ukwanda kokusetshenziswa kukaphethiloli okungavamile. I-atomization embi kaphethiloli izobangela ukusha okungaphelele kukaphethiloli, futhi injini izokwandisa ivolumu yokujova uphethiloli ukuze igcine amandla, okuholela ekwandeni okukhulu kokusetshenziswa kukaphethiloli.
Ukungenzi lutho nokunyakaza okungalingani nakho kuyizimpawu ezivamile. Ukuvaleka kwe-fuel injector noma i-atomization embi kuzobangela ukusatshalaliswa kukaphethiloli okungalingani ku-cylinder, kwandisa ukushintshashintsha komsebenzi wesilinda, futhi noma ngabe i-ECU yenza izinguquko, ayikwazi ukukhokhela ngokuphelele, ngaleyo ndlela ibangele ukuguquguquka kwesivinini sokungenzi lutho nokudlidliza kwemoto. Ngaphezu kwalokho, ukukhishwa okukhulu komoya ophumayo, ubunzima ekuqalisweni okubandayo, kanye nezibani zephutha lenjini ezikhanyisayo nakho kungaba izimpawu zokwehluleka kwe-fuel injector. Ukwehluleka okukhulu kwe-fuel injector nakho kungaholela ekuswelekeni kwesilinda senjini, ukuvalwa kwenjini okungazelelwe, kanye nezinye izinkinga ezinkulu ezithinta ukuphepha kokushayela.
Impendulo kanye nokuvimbela ukwehluleka kwe-fuel injector
Ukubhekana nokwehluleka kwe-fuel injector, izimpendulo ezifika ngesikhathi nezisebenzayo zibalulekile. Uma kuvela izimpawu ezingenhla, umnikazi angasebenzisa uhlelo lokuxilonga olusebhodini (i-OBD) kuqala ukuze afunde amakhodi amaphutha ukuze anqume imbangela yokwehluleka. Uma kuvinjelwa i-fuel injector encane, izithasiselo zikaphethiloli eziqukethe izingxenye ze-PEA zingasetshenziswa ekuhlanzeni. Ngokuvamile, ukuzisebenzisa izikhathi ezingu-2-3 kungancibilikisa futhi kususe amadiphozithi e-carbon ngempumelelo, kubuyisele i-fuel injector ekusebenzeni okuvamile.
Uma iphutha likhulu, njengevalvu yenaliti ebhajwe ku-injector kaphethiloli noma ikhoyili eshisiwe, kuyadingeka ukuya esitolo sokulungisa sochwepheshe ukuze silungiswe noma sishintshwe ngokushesha. Ngesikhathi senqubo yokulungisa, ochwepheshe abangochwepheshe bazosebenzisa imishini yobungcweti ukuhlanza, ukuhlola nokulungisa i-injector kaphethiloli ukuqinisekisa ukuthi ibuyela ekusebenzeni okuvamile.
Ukuvimbela ukwehluleka kwe-fuel injector kubaluleke kakhulu ekunakekelweni kwansuku zonke. Kunconywa ukuthi abanikazi bezimoto benze ukuhlolwa kwe-fuel injector kanye nokuhlanza kanye njalo ngamakhilomitha ayi-2-3 000. Uma imoto isebenzisa uphethiloli osezingeni eliphezulu futhi inakekelwa kahle, isikhathi singandiswa sibe ngamakhilomitha ayi-4-6 000. Ngesikhathi esifanayo, khetha isiteshi sikaphethiloli esithembekile ukuze wengeze uphethiloli osezingeni eliphezulu ukuze ugweme ukusebenzisa uphethiloli ongemuhle, okunganciphisa umonakalo we-fuel injector obangelwa ukungcola nezinsini kuphethiloli. Ngaphezu kwalokho, zama ukugwema ukungasebenzi isikhathi eside futhi unciphise ukuqala nokuyeka njalo ezimweni zethrafikhi zasemadolobheni, okunganciphisa ngempumelelo ukwakheka kwamadiphozithi e-carbon ku-fuel injector.
Ngamafuphi, i-fuel injector iyisici esibalulekile senjini, futhi umsebenzi wayo awukwazi ukushintshwa. Ukuqonda isimiso sokusebenza kanye nezimpawu zamaphutha ze-fuel injector, kanye nokuqonda impendulo efanele kanye nezindlela zokuvimbela, kungasiza abanikazi bezimoto ukuthola nokuxazulula izinkinga ngesikhathi, ukuqinisekisa ukuthi injini ihlala isesimweni esihle kakhulu sokusebenza futhi inikeze isivikelo esithembekile sokusebenza kwamandla emoto kanye nokuphepha kokushayela.
