Iyini isilawuli sesigaba semoto
Isilawuli sesigaba sezimoto yidivayisi eshintsha isikhathi sevalvu ngokulungisa i-Angle yesigaba futhi isetshenziswa kakhulu ukuthuthukisa ukusebenza kwenjini. Umsebenzi wayo oyinhloko ukulungisa isikhathi sokuvula nokuvala kwamavalvu ngokuya ngesivinini nomthwalo wenjini, ngaleyo ndlela kuthuthukiswe ukukhishwa kwamandla kanye nokonga uphethiloli.
Isakhiwo kanye nomgomo wokusebenza
Isilawuli sesigaba ngokuvamile sakhiwe umzimba womlawuli wesigaba, i-sprocket ye-camshaft, i-motor, njll., kanti isigaba se-camshaft silungiswa ngohlelo lwe-hydraulic noma i-motor drive. Isibonelo, isilawuli sesigaba sikagesi sixhuma i-camshaft ne-sprocket ngendlela yokushintsha isivinini esine-axis ezintathu, kanti imoto iqhuba ukulungiswa komehluko wesigaba ukuze kufezwe ukulungiswa okuguquguqukayo kwesikhathi se-valve.
Izimo eziyinhloko zohlelo lokusebenza
Isetshenziswa kakhulu ezinhlelweni zesikhathi zama-valve eziguquguqukayo (njenge-VVT), ezihlanganisa izidingo zezimo zokusebenza ezahlukene zenjini. Isibonelo, umlawuli wesigaba sokungenisa angathuthukisa ukusebenza kahle kokushisa, kuyilapho umlawuli wesigaba sokukhipha umoya anganciphisa ukuphazamiseka kwegesi yokukhipha umoya.
Ama-modulators esigaba sezimoto asetshenziswa kakhulu ukushintsha amapharamitha wesekethe ye-resonant ngokushintsha isignali, okubangela ukushintsha kwesigaba esignalini yesithwali ukuze kwakheke igagasi eliguquliwe ngesigaba. Asetshenziswa kakhulu ekuguquleni isignali kanye nokudlulisa izinhlelo zamandla.
Umsebenzi oyinhloko
Ukuguqulwa kwesiginali ye-Youdaoplaceholder0 : Ngokulungisa amapharamitha anjengokungenela kanye nomthamo wesekethe ye-resonant, isigaba sesiginali yenkampani siyashintshwa ukuze kufezwe ukuguqulwa kwesigaba sesiginali.
Ukulawula isekethe ye-Youdaoplaceholder0 : Kusetshenziswa ezinhlelweni zamandla ukulawula ukuzinza kwe-voltage, isibonelo, ukugcina i-voltage yokukhipha yejeneretha cishe ngenani elilinganiselwe (njenge-14V) ukuqinisekisa ukusebenza okuvamile kwemishini kagesi.
Umsebenzi wokuvikela we-Youdaoplaceholder0 : Uma kutholakala ukushaja okuningi noma kwenzeka ukugeleza okuphambene, isekethe inqanyulwa ngokushesha ukuvimbela ukushaja ngokweqile kwebhethri noma ukulimala kwemishini.
Umehluko kumlawuli wezimoto
Abalawuli besigaba bagxila ekucutshungulweni kwesignali kanye nokulawulwa kwesekethe, kuyilapho abalawuli bezimoto bezinikele kakhulu ekuzinzeni kwamandla kagesi kanye nokuvikelwa kokushisa ngokweqile ezinhlelweni zamandla. Izimo zokusetshenziswa kwalokhu okubili zihlukile, kodwa zombili zihilela ukulawulwa kwamapharamitha esekethe kanye nezindlela zokuvikela.
Umgomo wokusebenza womlawuli wesigaba sezimoto usekelwe kakhulu ohlelweni lwe-hydraulic noma i-motor drive. Ngokulungisa indawo ehlobene phakathi kwe-camshaft ne-crankshaft, isikhathi se-valve (okungukuthi, isikhathi lapho ama-valve evuleka futhi evalwa) siyashintshwa.
Umgomo wama-hydraulic phase modulators
Thatha uhlelo lwe-OCV VVT olufakwe eceleni njengesibonelo. Izingxenye zalo eziyinhloko yi-phase regulator kanye ne-oil control valve (OCV). I-phase regulator ilungisa indawo ehlobene phakathi kwe-camshaft sprocket kanye ne-rotor ngegumbi le-hydraulic, kanti i-oil control valve ilawula ingcindezi ye-hydraulic ngokwezimo zokusebenza kwenjini. Uma umthwalo uphansi, vala i-intake valve kusengaphambili; uma umthwalo uphezulu, yeka ukuvala i-intake valve ukuze uthuthukise ukuphuma kwamandla.
Umgomo womlawuli wesigaba sikagesi
Umlawuli wesigaba sikagesi usebenzisa isakhiwo esinama-axis amathathu: i-axis yokuqala ixhunywe ku-camshaft, i-axis yesibili iqhutshwa yimoto, kanti i-axis yesithathu ixhunywe ku-sprocket. Imoto ifinyelela ukulawulwa kwesigaba ngokulungisa umehluko wejubane. Lapho i-Angle yesikhathi esihle ilungisiwe, ama-axis amathathu ajikeleza ngokuvumelana. Lapho ilungisa isigaba, imoto ishayela ishaft ukuze isheshise noma yehle.
Zombili izinhlobo zidinga izinzwa ukuqapha izikhundla ze-crankshaft kanye ne-camshaft, nokulawula izenzo ze-actuator nge-ECU.
Amaphutha kumlawuli wemoto (ngokuvamile abhekisela kumlawuli wejenereyitha) angaholela ku-voltage engajwayelekile, ukuqala okunzima kanye nezinye izinkinga. Lokhu okulandelayo yizibonakaliso nezimbangela ezithile:
Izenzakalo ezivamile
I-anomaly ye-voltage ye-Youdaoplaceholder0
Ukukhiqizwa kwamandla ngokweqile kungaholela ekushajweni ngokweqile kwebhethri, kanti i-voltage kungenzeka idlule i-14V, okusheshisa ukuguga kwebhethri futhi kubangele nomonakalo. Uma ukukhiqizwa kwamandla kunganele, i-voltage ingaba ngaphansi kwe-10V, okuholela ekuqalisweni okunzima kanye nokusheshisa okubuthakathaka.
Amaphutha ahlobene nebhethri le-Youdaoplaceholder0
Uma isibani sesibonakaliso sebhethri singajwayelekile (sihlala sivuliwe noma sikhanya), impilo yebhethri izofinyezwa. Ezimweni ezimbi kakhulu, ingase ingakwazi ukugcina ugesi.
Ukusebenza kwenjini ye-Youdaoplaceholder0 kwehla
Uma injini inyakaza, isheshisa kancane noma imisa ngqo, idinga ukuhlolwa nokulungiswa ngesikhathi.
Imbangela yokungasebenzi kahle
Ukuguquguquka kwamandla kagesi e-Youdaoplaceholder0
I-voltage yokukhipha engazinzile yejeneretha (njengokushintshashintsha kwejubane lenjini kadizili kanye nezinguquko ezinkulu emthwalweni) kubangela ukuthi umlawuli alungise njalo, okusheshisa ukuguga kwezingxenye.
Umthwalo we-Youdaoplaceholder0 Oweqile kakhulu womshini
Ukusebenza kokulayisha ngokweqile isikhathi eside (njengokungasebenzi noma ukuvuza kukawoyela endaweni yejeneretha) kwandisa umthwalo wokusebenza womlawuli.
Ukuguga kwengxenye ye-Youdaoplaceholder0
Ama-transistor angaphakathi omlawuli (njenge-FET, ama-transistor aseDarlington) ayaphuka noma avuleke, okuholela ekulahlekelweni kwamandla okulawula.
