Iyini i-inverter yemoto
I-inverter yemoto iyithuluzi elisetshenziselwa ukulungisa indawo ehlobene phakathi kwe-camshaft yokungenisa kanye ne-crankshaft yenjini yemoto. Umsebenzi wayo oyinhloko ukulungisa isigaba se-camshaft nge-motor drive, ngaleyo ndlela kuthuthukisa ukusebenza kanye nokonga uphethiloli wenjini.
Isimiso sokusebenza
Abalawuli besigaba sezimoto bavame ukusebenzisa abalawuli besigaba sikagesi, futhi isakhiwo sabo sihlanganisa indlela yokudlulisa ene-axis ezintathu. Enye yemishayo ixhunywe ku-camshaft, enye ishaft iqhutshwa yimoto, kanti ishaft yesithathu ixhunywe ku-sprocket nge-stator. Lesi sakhiwo esiqinile semishini senza i-camshaft, i-phase regulation motor kanye ne-sprocket zisebenze ngokubambisana. Uma kudingeka ukulungisa i-timing Angle, imoto yenza isivinini sokujikeleza salezi zinhlangothi ezintathu sifane. Uma isigaba sidinga ukulungiswa, isivinini semoto sizoshesha noma sihambe kancane kunesivinini se-stator ngokwezimo zokusebenza, ekugcineni silawule isikhathi sokuvula/sokuvala i-valve .
Izinhlobo kanye nezimo zohlelo lokusebenza
Kunezinhlobo ezimbili eziyinhloko zezilawuli zesigaba sezimoto: uhlelo lwesikhathi se-valve eguquguqukayo (i-VVT) kanye nohlelo lokuphakamisa i-valve eguquguqukayo (i-VVL). I-VVT ithuthukisa ukuphuma kwe-torque kanye nokonga uphethiloli ngokulungisa isikhathi sokuvuleka kwe-valve yokungenisa kanye neyokukhipha, kuyilapho i-VVL ithuthukisa ukuphuma kwamandla kanye nokusebenza kahle kukaphethiloli ngokushintsha ukuphakanyiswa kwe-valve . Lezi zinhlelo zisetshenziswa kabanzi ezinjinini zezimoto zesimanje, ikakhulukazi kumamodeli anezidingo zokusebenza okuphezulu kanye nokusebenza kahle okuphezulu.
Ukunakekelwa kanye nokuxilongwa kwamaphutha
Ukuze kugcinwe umlawuli wesigaba semoto, kubaluleke kakhulu ukuhlola njalo isimo sokusebenza kwemoto kanye nokuqina kokuxhumeka kwemishini. Uma kutholakala ukuthi imoto ayisebenzi kahle noma ukulungiswa kwesigaba akulungile, kufanele kwenziwe ukulungiswa noma ukushintshwa kwezingxenye ezifanele ngesikhathi. Ngaphezu kwalokho, ukuhlanza njalo nokugcinwa kwesakhiwo semishini ukuqinisekisa ukusebenza kwayo okubushelelezi nakho kuyindlela ephumelelayo yokwandisa impilo yenkonzo yomlawuli wesigaba. Ngokuphathelene nokuHlola iphutha, ukunemba kwe-MOTOR CURRENT, i-VOLTAGE kanye nokulawulwa kwesigaba kungatholakala ngamathuluzi ochwepheshe okuxilonga, ukuthola nokuxazulula izinkinga ngesikhathi .
Umsebenzi oyinhloko we-modulator yesigaba semoto ukusebenzisa isignali eguquliwe ukushintsha ngqo amapharamitha e-resonant loop, ukuze lapho isignali yenkampani idlula ku-resonant loop, kukhiqizwe ushintsho lwesigaba ukuze kwakheke igagasi le-phase modulation .
Ngokukhethekile, i-motor phase modulator ifinyelela ukuguqulwa kanye nokususwa kwesignali ngokushintsha amapharamitha wesekethe ye-resonant ukuze ithonye ushintsho lwesigaba sesignali.
Isimiso sokusebenza
Umgomo wokusebenza womlawuli wesigaba sezimoto uhilela ukuguqula izimpawu kanye nezifunda eziphendulayo. Isignali ephenduliwe isetshenziselwa ukushintsha amapharamitha wesekethe esiphendulayo, okwenza isignali yomthwali ishintshe isigaba lapho idlula esekethe esiphendulayo futhi yakhe igagasi eliphendulayo. Le nqubo ihilela ukwakheka kwezifunda zikagesi kanye namasu okucubungula izimpawu ukuqinisekisa ukuthi i-modulator yesigaba ingalawula ngokunembile izinguquko zesigaba sesignali.
Izimo zohlelo lokusebenza
Ama-modulators esigaba sezimoto asetshenziswa kabanzi ezinhlelweni ze-elekthronikhi zezimoto, ikakhulukazi ezinhlelweni ezidinga ukulawulwa okunembile kwesigaba sesignali. Isibonelo, ezinhlelweni zokuxhumana, i-modulator yesigaba ingasetshenziswa ukuguqula nokunciphisa izimpawu ukuqinisekisa ukudluliswa okuzinzile kwezibonakaliso. Kumayunithi okulawula kagesi ezimoto, ama-modulators esigaba angasetshenziswa ukulawula ngokunembile izimpawu zezinzwa nama-actuator ahlukahlukene, okuthuthukisa ukuzinza nokuthembeka kohlelo.
Ukwehluleka kwe-inverter yemoto ye-Youdaoplaceholder0 kubonakala kakhulu njengezimo ezilandelayo:
I-Youdaoplaceholder0 Voltage anomaly : I-transistor ye-field-effect noma i-transistor yaseDarlington engaphakathi kwe-inverter iyaphuka, okwenza ukuthi ugesi wokukhipha amandla ungalawuleki, i-voltage yokukhipha amandla ejeneretha ikhuphuke noma yehle ngendlela engavamile, kanye nebhethri ukuthi lishajwe ngokweqile noma lishajwe kancane .
I-Youdaoplaceholder0 Ukunciphisa ukusebenza kahle kokushaja : Ijeneretha yonakele, i-voltage yokukhipha iyehla, futhi ayikwazi ukushaja ibhethri kahle, okuholela ekutheni amandla ebhethri anganele .
