Iyini inverter yemoto
I-automobile inverter iyithuluzi elisetshenziselwa ukulungisa indawo ehlobene phakathi kwe-camshaft yokudonsa kanye ne-crankshaft yenjini yemoto. Umsebenzi wayo oyinhloko ukulungisa isigaba se-camshaft ngokusebenzisa i-motor drive, ngaleyo ndlela kuthuthukisa ukusebenza nomnotho we-fuel injini.
Isimiso sokusebenza
Izilawuli zesigaba sezimoto zivame ukusebenzisa izilawuli zesigaba sikagesi, futhi ukwakheka kwazo kuhlanganisa indlela yokudlulisa yama-axis amathathu. Enye yezintambo ixhunywe ku-camshaft, enye i-shaft iqhutshwa yi-motor, kanti i-shaft yesithathu ixhunywe ku-sprocket ngokusebenzisa i-stator. Lesi sakhiwo esihlangene semishini senza i-camshaft, i-motor regulation motor kanye ne-sprocket zisebenze ngokubambisana. Uma kudingekile ukulungisa i-Angle yesikhathi, injini yenza isivinini sokujikeleza salezi zinhlangano ezintathu zifane. Lapho isigaba sidinga ukulungiswa, isivinini semoto sizoshesha noma sihambe kancane kunejubane le-stator ngokwezimo zokusebenza, ekugcineni silawule isikhathi sokuvula/ sokuvala i-valve .
Izinhlobo nezimo zohlelo lokusebenza
Ngokuyinhloko kunezinhlobo ezimbili zezilawuli zesigaba sezimoto: i-variable valve timing system (VVT) kanye ne-variable valve lift system (VVL). I-VVT ithuthukisa ukuphuma kwetorque nokonga kukaphethiloli ngokulungisa isikhathi sokuvuleka kwamavalvu okukhiphayo, kuyilapho i-VVL ithuthukisa ukuphuma kwamandla nokusebenza kahle kukaphethiloli ngokushintsha ukuphakamisa ama-valve. Lezi zinhlelo zisetshenziswa kakhulu ezinjini zesimanje zezimoto, ikakhulukazi kumamodeli anokusebenza okuphezulu kanye nezidingo ezisezingeni eliphezulu.
Ukugcinwa nokuxilongwa kwamaphutha
Ukuze kugcinwe isilawuli sesigaba semoto, kubaluleke kakhulu ukuhlola njalo isimo sokusebenza kwemoto kanye nokuqina kokuxhumeka kwemishini. Uma kutholakala ukuthi injini ayisebenzi kahle noma ukulungiswa kwesigaba akulungile, ukugcinwa okufika ngesikhathi noma ukushintshwa kwezingxenye ezifanele kufanele kwenziwe. Ngaphezu kwalokho, ukuhlanza nokugcinwa njalo kwesakhiwo semishini ukuze kuqinisekiswe ukusebenza kwayo kahle futhi kuyindlela ephumelelayo yokwandisa impilo yesevisi yomlawuli wesigaba. Mayelana ne-DIAGNOSIS yephutha, ukunemba KWE-MOTOR CURRENT, VOLTAGE kanye nokulawulwa kwesigaba kungatholwa ngamathuluzi okuxilonga angochwepheshe, thola futhi UXAZULULA izinkinga ngesikhathi .
Umsebenzi oyinhloko we-modulator yesigaba semoto ukusebenzisa isignali eguquliwe ukuze uguqule ngokuqondile imingcele ye-loop ye-resonant, ukuze kuthi lapho isignali yenkampani yenethiwekhi idlula iluphu ye-resonant, ukuguqulwa kwesigaba kukhiqizwa ukwenza i-wave modulation wave .
Ngokukhethekile, imoduli yesigaba sezimoto ifinyelela ukuguquguquka nokwehliswa kwesignali ngokushintsha amapharamitha wesekethe ezwakalayo ukuze ibe nomthelela ekushintsheni kwesigaba sesiginali.
Isimiso sokusebenza
Umgomo wokusebenza wesilawuli sesigaba sezimoto ubandakanya ukulungisa amasiginali namasekhethi anomsindo. Isignali eshintshiwe isetshenziselwa ukushintsha amapharamitha wesekethe ye-resonant, okwenza isignali yenkampani yenethiwekhi ishintshe isigaba lapho idlula kumjikelezo we-resonant futhi yakhe igagasi eliguquguqukayo lesigaba. Le nqubo ihilela ukuklanywa kwamasekhethi e-elekthronikhi nezindlela zokucubungula isignali ukuze kuqinisekiswe ukuthi imoduli yesigaba ingakwazi ukulawula ngokunembile izinguquko zesigaba sesiginali.
Izimo zohlelo lokusebenza
Amamojula wesigaba sezimoto asetshenziswa kakhulu ezinhlelweni zikagesi zezimoto, ikakhulukazi ezinhlelweni ezidinga ukulawulwa okunembile kwesigaba sesiginali. Isibonelo, ezinhlelweni zokuxhumana, i-modulator yesigaba ingasetshenziswa ukulungisa nokwehlisa amasignali ukuze kuqinisekiswe ukudluliswa okuzinzile kwamasignali. Kumayunithi okulawula ama-elekthronikhi ezimoto, ama-modulators wesigaba angasetshenziswa ukulawula ngokunembile amasiginali wezinzwa ezihlukahlukene nama-actuator, athuthukise ukuzinza nokuthembeka kwesistimu.
I-Youdaoplaceholder0 Ukwehluleka kwe-Automobile inverter kubonakala ikakhulukazi njengalezi zenzakalo ezilandelayo:
