Yintoni i-chopper yeemoto?
I-automotive phase shifter, edla ngokubhekisa kwi-actuator kwi-variable valve timing system (VVT), ikwaziwa ngokuba yi-camshaft phase regulator okanye i-timing regulator. Ayisosixhobo esizimeleyo "se-phase shifter" kodwa sisixhobo esiphambili senkqubo ye-valve ye-injini, esinoxanduva lokulungisa ngokuguquguqukayo amaxesha okuvula nokuvala kwee-intake okanye ii-exhaust valves ngokusekelwe kwisantya se-injini, umthwalo, kunye nezinye iimeko zokusebenza, ukuze kuphuculwe umbane ophumayo, ukonga amafutha, kunye nokusebenza kokukhupha umbane.
Umsebenzi wayo oyintloko kukutshintsha i-engile yesigaba esihambelanayo phakathi kwe-camshaft kunye ne-crankshaft, ngaloo ndlela ifezekisa ixesha levalvu eliguquguqukayo eliqhubekayo. Ixesha levalvu elizinzileyo lendabuko alinakuziqhelanisa nazo zonke iimeko zokusebenza, ngelixa i-phase shifter inokufezekisa "uhlengahlengiso olukrelekrele":
Ngesantya esiphantsi kunye nemithwalo ephantsi: Qhubeka uvuleka kwevalvu yokungenisa ukuze wonyuse umthamo wokungenisa, wonyuse i-torque kunye nobuthambileyo.
Ngesantya esiphezulu kunye nemithwalo ephezulu: Libazisa ukuvalwa kwevalvu yokungenisa, usebenzise ithuba lesiphumo se-inertia yokungenisa ukuphucula ukusebenza kakuhle kokutshaja kunye nokuphucula ukuphuma kwamandla.
Iintlobo kunye nemigaqo yokusebenza ye-phase shifter
I-Hydraulic phase shifter (eqhelekileyo)
Iqhutywa luxinzelelo lweoyile yenjini ngokusebenzisa iirotor zangaphakathi zohlobo lweblade okanye ezimile okwebhloko, zitshintsha indawo ephakathi kwe-camshaft kunye nevili letyathanga. Ivalvu yokulawula ioyile (i-OCV) ilawula isekethe yeoyile ngokomyalelo we-ECU ukuze kufezekiswe ixesha elibekiweyo okanye elilibazisekileyo.
Ulwakhiwo: Luquka i-stator, i-rotor, igumbi le-hydraulic, i-lock pin, kunye ne-return spring, njl.
Imida: Isantya sohlengahlengiso kunye nokuchaneka kuyachaphazeleka luxinzelelo kunye nobushushu beoyile yenjini, kwaye ngokuqhelekileyo kunokulungiswa kuphela ukusuka "kwisigaba sokuqala" kwicala elinye.
I-Electric phase shifter (iteknoloji entsha)
Iqhutywa ngqo yimoto, ilungelelanisa umahluko wesantya sokujikeleza phakathi kwe-camshaft, ivili letyathanga, kunye nemoto ngesakhiwo somatshini esinee-axis ezintathu ukuze kufezekiswe uhlengahlengiso lwesigaba oluchanekileyo nolukhawulezayo.
Iingenelo: Impendulo ekhawulezayo, ukuchaneka okuphezulu kolawulo, akuchaphazeleki ziimeko zeoyile yenjini, kunye nokuzivumelanisa nezimo okunamandla.
Iingxaki: Ibiza kakhulu kune-hydraulic type, okwangoku isetyenziswa kakhulu kwizithuthi ezikumgangatho ophezulu.
Ukungaqondani okuqhelekileyo kuyacaciswa
I-Phase shifter ≠ phase sensor: I-phase sensor (njenge-camshaft position sensor) "liliso" elibona izikhundla zevalvu, ngelixa i-phase shifter "lisandla" esenza uhlengahlengiso.
I-Phase shifter ≠ frequency converter okanye i-signal modulator: Ezinye izinto ezingezizo iimoto zikhankanya "i-phase shifter" ebhekisa kuhlengahlengiso lwe-electronic signal phase, olungadibaniyo nolwakhiwo lwe-mechanical yenjini.
I-chopper yeemoto yenye yeendlela eziphambili zeenjini zanamhlanje zokufezekisa ukusebenza kakuhle, ukhuseleko lokusingqongileyo, kunye nokusebenza okuphezulu. Iphucula ngokuguquguqukayo ixesha lokuvulwa nokuvalwa kwevalvu, ivumela injini ukuba "iphefumle" kakuhle phantsi kweemeko ezahlukeneyo zokusebenza. Okwangoku, uhlobo oluqhelekileyo yi-hydraulic, ngelixa uhlobo lombane luba ngumkhwa wexesha elizayo.
Igama elithi "chopper" kwicandelo leemoto lisenokuba ligama elingafanelekanga. Esihlala sithetha ngalo yi-generator regulator (ekwaziwa ngokuba yi-voltage regulator), eyiyona nto iphambili kwinkqubo yokutshaja yesithuthi kwaye inoxanduva lokuzinzisa i-voltage output ye-generator. Ukuba ayiphumeleli, iya kuchaphazela ngqo umbane kunye nokusebenza kwesithuthi.
Nazi iimpawu eziqhelekileyo, izizathu, kunye nezisombululo zeempazamo kumlawuli wejenereyitha yeemoto:
Ingxaki Ephambili:
- Isibane sesalathisi sebhetri esingaqhelekanga: Isibane sesibonakaliso sebhetri (sokutshaja) kwideshibhodi sihlala sivuliwe okanye sikhanya, esiluphawu lwesilumkiso oluthe ngqo, olubonisa ukuba inkqubo yokutshaja ayisebenzi kakuhle.
- I-voltage yebhetri engaqhelekanga:
- Umbane ophantsi (ngaphantsi kwe-12V): Ubangela ukutshaja kwebhetri okunganelanga, okubangela ubunzima ekuqaliseni imoto, izibane zemoto ezifipheleyo, ukusebenza okungaqhelekanga kwezixhobo ze-elektroniki, kwanokucima injini ngequbuliso ngexesha lokuqhuba.
- Umbane ophezulu (ngaphezulu kwe-14.5V): Ubangela ukutshaja kakhulu kwebhetri, ukukhawulezisa ukusetyenziswa kwe-electrolyte ngaphakathi kwebhetri, ukudumba, umonakalo, kwaye kwiimeko ezinzima, kunokubangela umngcipheko wokuqhuma kwebhetri.
- Ukusebenza kwesithuthi okunciphileyo: Ngenxa yombane ongazinzile, kunokubangela ukusebenza okungaqhelekanga kweyunithi yokulawula injini (ECU), okubangela ukushukuma kwenjini, ukukhawulezisa okunganelanga, isantya esingazinzanga, kwanokucima injini ngequbuliso.
- Ukungasebenzi kakuhle kwezixhobo zombane: Izibane zezithuthi, iinkqubo zesandi, iifestile, njl.njl., zinokuba nokusebenza okwethutyana, ukukhanya okungaqhelekanga, okanye umonakalo othe ngqo ngenxa yombane ongaguqukiyo.
Izizathu Eziqhelekileyo Zeziphene:
- Ukusilela kwezixhobo ze-elektroniki zangaphakathi: Ii-transistors ze-field-effect (ii-FET) okanye ii-transistors zaseDarlington ezingaphakathi kwi-regulator zinokwaphuka okanye zivuleke ngenxa ye-overvoltage, ubushushu obugqithisileyo, okanye ukuguga, nto leyo ebangela ukungazinzi kwe-voltage (nokuba iphezulu kakhulu okanye iphantsi kakhulu).
- Izinto ezisingqongileyo: Amaqondo obushushu aphezulu kwindawo yenjini, ukufuma, kunye nokuqhuba ixesha elide kwiindlela ezinamaqhuqhuva kuyakhawulezisa ukuguga komlawuli.
- Ukuguquguquka kweVolthi kwijenereyitha: Xa i-voltage yokukhupha ijenereyitha ingazinzanga okanye umthwalo utshintshatshintsha kakhulu, wonyusa umthwalo kwisilawuli, nto leyo ebangela ukuba sisebenze rhoqo kwaye sinokonakalisa.
- Iingxaki zocingo: Iiplagi zokudibanisa ezikhululekileyo nezidlakadlaka, okanye imigca yoqhagamshelo ephukileyo nefutshane nayo inokuthintela umlawuli ekusebenzeni kakuhle.
Iindlela zokuxilonga kunye nezisombululo:
- Isigwebo sokuqala: Okokuqala, jonga imeko yesibane sesalathisi sokutshaja kwideshibhodi uze ulinganise i-voltage phakathi kwee-terminals zebhetri nge-multimeter (ngelixa injini isebenza). I-voltage eqhelekileyo kufuneka ibe phakathi kwe-13.8V kunye ne-14.5V. Ukuba i-voltage iphantsi kakhulu okanye iphezulu kakhulu, ngokubanzi kunokugqitywa ukuba umlawuli okanye ijenereyitha inempazamo.
- Ukuxilongwa kobuchwephesha: Kucetyiswa ukuba undwendwele ivenkile yokulungisa iimoto yobungcali. Iingcali ziza kusebenzisa izixhobo ezizodwa zokuxilonga ukuze zifunde iikhowudi zeempazamo kwaye zenze uhlolo olupheleleyo lwejenereyitha, umlawuli, kunye nesekethe yokutshaja yonke ukuze zifumane ngokuchanekileyo indawo yeempazamo.
- Isicwangciso sokulungisa:
- Buyisela umlawuli endaweni yakhe: Kubalawuli be-elektroniki, ukuba umonakalo uqinisekisiwe, ukuwutshintsha ngokuthe ngqo sesona sisombululo sikhawulezayo nesithembekileyo.
- Jonga iingcingo: Ngaphambi kokuba ufake isilawuli endaweni yaso, qiniseka ukuba imigca yoqhagamshelo kunye neeplagi zikwimeko entle ukuze kuthintelwe ukuba inxalenye entsha yonakale ngenxa yeengxaki zengcingo.
- Jonga ijenereyitha: Ngamanye amaxesha, iimpazamo kwijenereyitha ngokwayo (ezifana neebhrashi, izinto zokulungisa) nazo zinokubonakala njengeengxaki zokulawula, ngoko ke kufuneka zijongwe kunye.
Nceda uqaphele: "I-electronic chopper" ekhankanyiweyo kwi-intanethi idla ngokusetyenziswa kwiimoto zombane okanye iidrone kwaye yinxalenye eyahlukileyo ngokupheleleyo kwi-automotive generator regulator. Kukwakho "ne-regulator" kwinkqubo yomoya opholileyo yesithuthi, kodwa umsebenzi wayo kukulawula ukuvulwa nokuvalwa kwe-air vents, kwaye ayinxulumananga nenkqubo yokutshaja. Ukuqinisekisa ukhuseleko lokuqhuba, ukuba kukho naziphi na iimpawu ezingasentla, nceda wenze uhlolo lobuchwephesha ngoko nangoko. Musa ukuqhuba nesithuthi esineengxaki.
