Yintoni i-sensor ye-camshaft yemoto
I-automotive camshaft sensor (ekwaziwa ngokuba yi-synchronous signal sensor) sisixhobo esisetyenziselwa ukubona indawo kunye ne-Engela ye-camshaft, ebonelela ngesignali ephambili yokulawula ukutsha kwi-ECU ukuqinisekisa ukusebenza kakuhle nokuzinzileyo kwenjini.
Umsebenzi oyintloko
I-Youdaoplaceholder0 Chonga ucalucalulo lwesilinda kunye nendawo esikuyo: Ngokubona indawo ye-camshaft ngexesha langempela, inceda i-ECU ukuba ichonge ngokuchanekileyo iziko eliphezulu elifileyo lokucinezelwa kwepiston yesilinda yokuqala, ifezekise ulawulo lokufaka amafutha ngokulandelelana, uhlengahlengiso lwexesha lokutsha kunye nolawulo lokuqhushumba.
I-Youdaoplaceholder0 Igalelo lesiginali kwi-ECU: Guqula i-Angle eguquguqukayo ye-camshaft ibe yigalelo lesiginali yombane kwi-ECU, esebenza njengesiseko solawulo esiphambili sokutsha kunye nokufakwa kwepetroli.
Indawo yokufakelwa
Ihlala ifakelwa kwisiphelo esingaphambili sekhava ye-camshaft (njengesiphelo esingaphambili se-camshaft yokungenisa enguNombolo 1 yenjini yeToyota K3-VE), kwaye kwezinye iimodeli, ifakwe ngaphakathi kwimpompo yeoyile enoxinzelelo oluphezulu okanye kwi-distributor.
Uhlobo kunye nomgaqo wokusebenza
Isebenzisa isakhiwo semagnethi-electric. Ngokubona utshintsho kumbane obangelwa lutshintsho lwemagnethi xa i-CAM ijikeleza, iyiguqula ibe yisignali yendawo. Umzekelo, inzwa yemagnethi-electric enezikhonkwane ezintathu yenjini yeToyota K3-VE ikhupha imiqondiso yepulse nge-time pin (emele ii-angles ze-crank ezingama-60°, 180°, kunye ne-360°).
Iimpawu eziphambili ze-sensor ye-camshaft engasebenzi kakuhle emotweni ziquka ubunzima bokuqalisa, isantya esingazinziyo sokungaqhubi kakuhle, ukusetyenziswa kwepetroli okwandisiweyo, izibane ze-fault ezikhanyisiweyo, ukukhawulezisa okubuthathaka kunye nokushukuma komzimba. Ezi mpawu zibangelwa kukungakwazi kwe-sensor ukuhambisa ngokuchanekileyo imiqondiso yendawo ye-camshaft kwi-ECU, okukhokelela kwiingxaki kwiinkqubo zokutsha kunye nokufakwa kwepetroli.
Iimpawu eziphambili zezi
Ubunzima bokuqalisa okanye ukungakwazi ukuqala: Ulandelelwano lokutsha luphazamisekile, injini kunzima ukuyiqalisa, kwaye inokuma ngequbuliso xa ifudumala.
I-Youdaoplaceholder0 Isantya esingazinzanga sokungashukumi kunye nokushukuma komzimba wesithuthi : I-ECU ifumana imiqondiso engalawulekiyo, nto leyo ebangela utshintsho olukhulu kwisantya sokungashukumi kunye nokushukuma okungaqhelekanga kwesithuthi.
I-Youdaoplaceholder0 Ukwanda okukhulu kokusetyenziswa kwepetroli: Inkqubo yokufaka ipetroli isebenza ngokungalungelelananga, nto leyo ebangela ukutsha kwepetroli okungaphelelanga kunye nokwanda kokusetyenziswa kwepetroli.
I-Youdaoplaceholder0 Ukukhawulezisa okubuthathaka kunye nokuqhuba ngokuxhamazela : I-ECU iyasilela ukulawula ngokuchanekileyo ukufakwa kwamafutha kunye nokutsha, nto leyo ebangela umbane othambileyo kunye nokukhawulezisa okucothayo okanye okuxhamazelayo.
Isibane sempazamo sihlala sivuliwe: inkqubo ye-OBD ibona into engaqhelekanga ize iqalise isibane sempazamo yenjini (ezifana neekhowudi zempazamo ze-P0340-P0344).
I-Youdaoplaceholder0 Ukonakala kwenjini okukhawulezileyo : Ukungasebenzi kakuhle kwexesha elide kunokukhokelela ekutshisweni okungaphelelanga kwaye kuqinise ukubola kwenjini yangaphakathi.
Impembelelo enokubakho ye-Youdaoplaceholder0
Iziphene zinokubangela ukonakala kokukhutshwa komoya, ukunqongophala kwamandla (indlela yokuqhwalela), okanye ukuma ngexesha lokuqhuba. Ulondolozo olukhawulezileyo luyadingeka ukuthintela umonakalo wenjini.
I-sensor ye-camshaft yeemoto ifuna ukucocwa okujoliswe kuko ngokusekelwe kwiimeko zokusetyenziswa. Xa kukho ukwehla kwamandla, ukusetyenziswa kwepetroli okungaqhelekanga okanye iikhowudi zempazamo, ukucoca kunokubuyisela ngokufanelekileyo ukusebenza kwe-sensor. Ukuba akukho ziphazamiso, ukucoca rhoqo akufuneki.
Ukuzimisela kwe-Youdaoplaceholder0 ngemfuneko yokucoca
I-Youdaoplaceholder0 kufuneka icocwe :
Injini ifumene izinto ezingaqhelekanga ezifana nobunzima bokuqalisa, ukuphazamiseka kwamandla, kunye nokunyuka okukhulu kokusetyenziswa kwepetroli (umzekelo, kwimeko yeBMW, ukusetyenziswa kwepetroli kwehle ukusuka kwi-12.8L ukuya kwi-8.2L/100km).
I-ECU ibona iikhowudi zeempazamo ezinxulumene nesensor yendawo ye-camshaft (ezifana ne-P0340/P0341).
I-oyile emdaka okanye ii-iron filings ezinamathele kumphezulu we-sensor (ukuba ubukhulu bungaphezulu kwe-0.3mm, kufuneka ziphathwe).
Iimeko ze-Youdaoplaceholder0 apho kungekho mfuneko yokucoca:
Isensor isongelwe kwiscreen sesihluzo esidityanisiweyo kwaye ihlanjwa rhoqo ngeoyile yenjini (njengoko yenzelwe kwezinye iimodeli zezithuthi).
Xa ilungiswa rhoqo, injini isebenza kakuhle ngaphandle kwekhowudi yeziphene.
Isikhokelo sokusebenza ngokucoca sobuchwephesha seYoudaoplaceholder0
Amanqaku aphambili e-Youdaoplaceholder0 okuqhaqha nokuhlanganisa :
Sebenzisa isingxobo se-10mm uze usijikelezise ngasemva ngama-30° ukuze uvuleke. Yishukumise kancinci ukuze uthintele ukuba izinto ezitsala umbane zingawi.
Nqamla isiphelo sebhetri esingalunganga ukuthintela i-short circuit.
Iinkcukacha zokucoca ze-Youdaoplaceholder0 :
Futha isicoci sekhabharetha kwi-engile engama-45°, ugxile ekucoceni izithuba zerotor (ingadluli kwimizuzu emi-2).
Kwimibala engapheliyo, sebenzisa ibrashi ethambileyo kunye nesicoci se-elektroniki ukuze ukhuhle kancinci.
Iikhrayitheriya zokwamkelwa ze-Youdaoplaceholder0 :
Umjikelo womsebenzi wamaza esikwere afunyenwe yi-oscilloscope kufuneka ube phakathi kwe-45% kunye ne-55%.
Emva kokufaka kwakhona, ikhowudi yempazamo kufuneka icocwe kwaye isatifikethi sovavanyo lwesekethe siqhagamshelwe.
Ingcebiso yomjikelo wolondolozo we-Youdaoplaceholder0:
Ukucoca okuthintelweyo kwe-Youdaoplaceholder0:
Jonga ngokulandelelana rhoqo emva kweekhilomitha ezingama-60,000 okanye xa ibhanti yexesha itshintshiwe.
Izithuthi ebezisebenzisa ioyile yenjini ekumgangatho ophantsi ixesha elide kufuneka zihlolwe zifinyezwe ziye kwiikhilomitha ezingama-30,000.
Ulondolozo lwemihla ngemihla lwe-Youdaoplaceholder0:
Jonga ukuba iplagi yesensa iyavuza na ngalo lonke ixesha utshintsha ioyile yenjini.
Gcina indawo yenjini icocekile kwaye uphephe ukutshiza ngqo imipu yamanzi enoxinzelelo oluphezulu kwindawo yesensa.
