Yintoni i-sensor ye-camshaft yemoto
I-Youdaoplaceholder0 I-Camshaft Position Sensor (CPS) sisixhobo esisetyenziselwa ukuqokelela imiqondiso yendawo ye-camshaft kwaye isetyenziswa kakhulu kwiinkqubo zolawulo lweenjini. Imisebenzi yaso ephambili ibandakanya ukufaka imiqondiso yendawo ye-camshaft kwiyunithi yolawulo lwe-elektroniki (ECU) ukumisela ixesha lokutsha kunye nexesha lokutsalwa kwepetroli, ukunceda i-ECU ichonge iziko elifileyo le-cylinder 1 compression top ukuze kufezekiswe ulawulo lokutsalwa kwepetroli olulandelelanayo, ulawulo lwexesha lokutshalwa kwepetroli kunye nolawulo lokucinywa kwepetroli .
Indawo yokufakela
I-sensor ye-camshaft idla ngokufakwa kwisiphelo esingaphambili sekhava ye-camshaft, ijonge ngqo phambili kwe-camshafts yokungenisa kunye neyokukhupha umoya. Olu fakelo luqinisekisa ukuba i-sensor ibamba ngokuchanekileyo isignali yendawo ye-camshaft ize iyithumele kwi-ECU.
Umgaqo wokusebenza
Iisensa zeCamshaft zisebenzisa i-magnetoelectric effect okanye i-Hall effect ukufumanisa indawo kunye nesantya sokujikeleza kwe-camshaft. Umzekelo, i-magnetoelectric camshaft position sensor ibala indawo kunye nesantya se-camshaft ngokufumanisa utshintsho kumbane obangelwe kwi-sensor coil eveliswa zizinto zemagnethi njengoko i-camshaft ijikeleza .
Indlela yokuchongwa kwempazamo
Xa uhlola isenzi se-camshaft, ungafumanisa ukuba sisebenza kakuhle na ngokukhupha iplagi yaso uze uvule iswitshi yokutsha, kunye nokusebenzisa ipeni yesibane sovavanyo ukuvavanya iingcingo ezintathu (intambo yamandla, intambo yesignali kunye nentambo yomhlaba). Ukuba i-voltage yesignali yahluka phakathi kwe-0 kunye ne-5 volts, isenzi sisebenza kakuhle. Ngaphandle koko, isenzi sinokonakala .
Ukungaphumeleli kwesensor ye-camshaft yemoto kubonakala kakhulu njengokuqala okunzima, isantya esingazinzanga sokungaqhubeki kakuhle, ukukhawulezisa okubuthathaka, ukusetyenziswa kwepetroli okwandisiweyo, ukukhanya kwempazamo okuhlala kuvuliwe, kunokukhatshwa kukushukuma kwenjini, ukuxhuzula, ukuma kwemoto eshushu, njl. Ezi mpawu zivela kwimiqondiso yesensor engaqhelekanga, ethintela i-ECU ekulawuleni ngokuchanekileyo ixesha lokutsha kunye nexesha lokufaka ipetroli, ngaloo ndlela ichaphazela ukusebenza kwenjini iyonke.
Iimpawu zokusilela kwe-Youdaoplaceholder0 Core
Ubunzima bokuqalisa: Ngenxa yokuphazamiseka kwexesha lokutsha, kungathatha imizamo emininzi ukuqala okanye ukungaphumeleli ukuqala konke konke. Kwezinye iimeko, ukujikeleza kwe-crankshaft reverse kunye ne-intake manifold backfire ziyaboniswa.
Ukungazinzi kwe-Youdaoplaceholder0 IDLE : Ukushukuma okungaqhelekanga kwenjini, ukuguquguquka okucacileyo kwisantya senjini, okufana nesilinda esingekhoyo, kwaye kwiimeko ezinzima kubangela imo yokuqhwalela.
I-Youdaoplaceholder0 Dynamic anomaly :
Ukukhawulezisa okubuthathaka kunye nokuphendula kancinci, imeko inokuba mandundu ngaphezu kwe-2500rpm
Kukho ukushukuma okucacileyo ngexesha lokuqhuba, ingakumbi xa uqhuba ngesantya esiphezulu okanye unciphisa isantya
Ukwehla koqoqosho lwe-Youdaoplaceholder0:
Ukusetyenziswa kwepetroli kunyuke nge-10%-30% ngenxa yokusilela kolawulo lomthamo wokufakwa kwepetroli
Ukukhupha umoya ongcolileyo kuyawohloka, umbhobho wokukhupha umoya uhlala unomsi omnyama
Isilumkiso sempazamo se-Youdaoplaceholder0: Isibane sempazamo yenjini sihlala sivuliwe, kwaye inkqubo ye-OBD idla ngokurekhoda ikhowudi yochungechunge lwe-P0340-P0344.
Iimpawu kunye neengozi ze-Youdaoplaceholder0
I-Youdaoplaceholder0 Injini eshushu iyama: Injini ingama ngequbuliso emva kokuba ifudumale kwaye kufuneka iqaliswe kwakhona ukuze isebenze
Ukuguguleka kwecandelo le-Youdaoplaceholder0: Ukungasebenzi kakuhle kwexesha elide kuya kukhawulezisa ukuguguleka kwezixhobo ezifana neepiston kunye neendonga zesilinda, nto leyo eya kunciphisa ubomi benjini.
I-Youdaoplaceholder0 Umngcipheko wokhuseleko: Ukuphazamiseka kwamandla okanye ukuthintelwa ngexesha lokuqhuba (indlela yokuqhwalela) kwandisa amathuba eengozi zequbuliso.
Izinzwa zesikhundla se-camshaft yezithuthi zihlala zimbini okanye ngaphezulu, kuxhomekeke kulwakhiwo lwenjini.
Inani lee-sensors zesikhundla se-camshaft kwiimoto liyahluka ngokuxhomekeke kuyilo lwenjini kunye neemfuno zokusebenza, kwaye lahlulwe ngokubanzi kwezi meko zimbini zilandelayo:
Uqwalaselo lwe-Youdaoplaceholder0 Single-sensor
Iqhele ukubonwa kwiinjini ezisisiseko okanye kwiinkqubo ezenza ulawulo lwexesha oluguquguqukayo kuphela kwiivalvu zokungenisa (ezifana nezinye iimodeli ezisebenzisa ubuchwepheshe beVVT). Iisensors zihlala zifakelwa kwisiphelo esingaphambili se-camshaft yokungenisa kwaye zisetyenziselwa ukubonelela ngesignali yokulawula ephambili yokulawula ukutsha kwi-ECU.
Umzekelo: Ezinye iimodeli zezithuthi zilungisa ixesha levalvu yokungenisa ngesenzi esinye kuphela, ngelixa ivalvu yokukhupha umoya ihlala ihleli.
Uqwalaselo lwe-Youdaoplaceholder0 Dual-sensor
Iqhele ukubonwa kwiinkqubo ezilawula ngaxeshanye ixesha eliguquguqukayo leevalvu zokungenisa kunye nezokukhupha umoya (ezifana netekhnoloji ye-VVT ezimbini). Ezi sensor zimbini zihambelana ngokulandelelana nee-camshaft zokungenisa kunye nezokukhupha umoya ukuze kufezekiswe uhlengahlengiso oluchanekileyo lwesigaba.
Umzekelo, injini yesizukulwana sesithathu se-EA888 isebenzisa ngokucacileyo izinzwa ezimbini (enye yokungenisa kunye nenye yokukhupha umoya).
Isishwankathelo samanqaku aphambili e-Youdaoplaceholder0:
Inani lee-sensors linxulumene nobunzima bobuchwephesha benjini. Iimodeli ezisisiseko zihlala zine-sensor enye, ngelixa iimodeli eziphezulu okanye ezisebenzayo zinamathuba amaninzi okusebenzisa ezimbini.
Ikwaziwa ngokuba yi-"synchronous signal sensor" okanye "Cylinder discrimination and Positioning device", umsebenzi ophambili wazo zombini kukudlulisela ulwazi lwesigaba se-camshaft kwi-ECU.
Indawo yokufakela kufuneka ihambelane ngqo nevili lesignali; kungenjalo, ukuqokelelwa kwedatha ngokuchanekileyo akunakufezekiswa.
