Yintoni i-sensor ye-camshaft yemoto
I-Youdaoplaceholder0 I-automotive camshaft position sensor (CPS) sisixhobo esisetyenziselwa ukubona indawo kunye ne-Engela ye-camshaft, enika imiqondiso kwi-ECU (iYunithi yoLawulo lweNjini) ukulawula iiparameter zenjini eziphambili ezifana nexesha lokutsha, ixesha lokujova ipetroli, kunye nolawulo lokuqhushumba.
Umsebenzi oyintloko
Indawo yecylinder: Ngokubona indawo ye-camshaft, i-compression top dead center (BTDC) ye-piston yesilinda yokuqala imiselwa ukuba ifikelele ekufakweni kwepetroli ngokuchanekileyo kunye nolawulo lokutsha.
Isignali ehambelanayo: Njengesignali yokulawula ephambili yolawulo lokutsha, iqinisekisa ukuba isilinda nganye yenjini isebenza ngokulandelelana.
Umgaqo wokusebenza
Ukuveliswa kwesignali: Isensor ine-light-emitting diode (LED) kunye ne-phototransistor ngaphakathi. Ngemingxunya yokudlulisa ukukhanya kunye neendawo ezithintela ukukhanya kwidiski yesignali, imiqondiso ye-pulse ephezulu nephantsi iveliswa ngokutshintshiselana.
Uhlobo lwesignali
Isignali ye-Ne: Ibonisa indawo ye-crankshaft kwaye ivelisa ii-pulses ezingama-360 ngokujikeleza ngakunye.
Isignali ye-G: Ibonisa indawo ye-camshaft, ivelisa ii-pulses ezi-6 ngokujikeleza ngakunye (ezihambelana ne-120° crankshaft rotation Angle).
Iindidi eziqhelekileyo
Uhlobo lwe-Photoelectric: Ukusebenzisa izinto ezibonisa ukukhanya ukuze kubonwe imingxunya yokudlulisa ukukhanya kwidiski yesignali.
Uhlobo lokungenisa iMagnetic: Lwahlulwe ngohlobo lweHall (isignali ye-amplitude esisigxina) kunye nohlobo lwe-magnetoelectric (ububanzi buyahluka ngokwesantya sokujikeleza).
Impembelelo yempazamo
Iimpawu zempazamo: Inokubangela ukuba injini ingaqalisi, amandla anciphe, ukusetyenziswa kwepetroli kwande okanye kunqonqoze.
Iimodeli eziqhelekileyo: Umzekelo, i-Audi Q5 ka-2015 ixhotyiswe ngee-camshafts ezimbini kwaye ifuna ii-sensors ezimbini zokujonga ngokwahlukeneyo.
Xa i-sensor ye-camshaft yemoto ingasebenzi kakuhle, iimpawu ezinje ngobunzima bokuqalisa, amandla aphantsi, ukusetyenziswa kwepetroli okwandileyo, ukungcangcazela komzimba, kunye nesibane sokulumkisa esikhanyayo zihlala zisenzeka. Oku kubonakala ngolu hlobo lulandelayo:
I-Youdaoplaceholder0 Ukuqalisa okungaqhelekanga : Injini ayivuthi okanye kunzima ukuyiqalisa. Kungathatha imizamo emininzi ukuze iphumelele. Oku kunokwenzeka kwiimeko ezibandayo nezishushu zenjini.
Ingxaki yokukhupha amandla e-Youdaoplaceholder0: ukukhawulezisa okungenamandla, impendulo ecothayo ye-throttle, kunye nokungabikho kwamandla okubonakalayo ngexesha lokuqhuba, nokuba kuhamba nokungcangcazela komzimba.
I-Youdaoplaceholder0 Ukuwohloka koqoqosho lwepetroli : Ukusetyenziswa kwepetroli kunyuke kakhulu ngenxa yokungakwazi kwe-ECU ukulawula ngokuchanekileyo umthamo wokufakwa kwepetroli, nto leyo ebangele ukutsha kwepetroli okungaphelelanga.
I-Youdaoplaceholder0 Ukusebenza okungazinzanga : Isantya senjini asizinzanga kwaye ukungcangcazela kubonakala xa ingasebenzi. Ukungcangcazela kuyaqina xa umthwalo uphezulu. Ezinye izithuthi zinokuba nengxaki yokuqhuba okanye ukuma ngequbuliso xa zifudumala.
I-Youdaoplaceholder0 Isilumkiso sempazamo: Isibane sempazamo yenjini kwideshibhodi (ezifana neekhowudi zempazamo ze-OBD P0340-P0344) sihlala sivuliwe rhoqo, nto leyo ebonisa ukuba inkqubo ifumene isignali engaqhelekanga.
Ukuba kuvela ezi mpawu zingasentla, kucetyiswa ukuba injini ihlolwe kwaye ilungiswe ngexesha elifanelekileyo ukuthintela ukuguguleka okuqhubekayo kwenjini.
Emva kokuba isivamvo sendawo ye-camshaft singasebenzi kakuhle, imoto ayikwazi ukusebenza ngendlela eqhelekileyo. Ukuqhuba ngenkani kunokubangela umonakalo omkhulu kwinjini kunye neengozi ezinokubakho zokhuseleko ezifana nokuma ngelixa uqhuba. Kufuneka ukulungiswa ngokukhawuleza.
Impembelelo yeziphene kumthamo wokuqhuba
I-sensor yendawo ye-camshaft yinxalenye ephambili yenkqubo yolawulo lwenjini, enoxanduva lokubonelela ngemiqondiso yesigaba se-camshaft kwi-ECU (iYunithi yoLawulo lwe-Electronic) ukulawula ngokuchanekileyo ulandelelwano lokutsha, ixesha lokufakwa kwepetroli, kunye nokunciphisa ukudubula. Nje ukuba yonakele, i-ECU ayinakukwazi ukubona ngokuchanekileyo indawo yesilinda, nto leyo ekhokelela ekubeni ulawulo lwenjini lungaphumeleli kwaye imoto ingakwazi ukugcina ukusebenza okuqhelekileyo. Ibonakala ngokukodwa ngolu hlobo:
Isibambi sendawo seYoudao0 Kunzima ukuqala okanye ukungakwazi ukuqala: Emva kokusilela kwesivamvo, i-ECU kufuneka ixhomekeke kwisignali yendawo ye-crankshaft ukuze igqibe ngokungathanga ngqo indawo ye-camshaft, nto leyo ebangela ukulibaziseka kokuvumelanisa ukutsha kunye nokufakwa kwepetroli. Ngexesha lokuqala okubandayo, kusenokufuneka imizamo emininzi okanye ukungaphumeleli ngokupheleleyo kunokwenzeka.
Ukuma ngequbuliso kwenjini ngexesha lokuqhuba: Ingakumbi phantsi kweemeko ezishushu okanye ezinomthwalo omninzi, injini isenokucima ngequbuliso ngenxa yokuphazamiseka kolawulo, nto leyo eyonyusa umngcipheko weengozi.
I-Youdaoplaceholder0 Umbane okhutshwayo kancinci: I-ECU iza kungena kwimo yokukhusela iimpazamo (imo yokuqhwalela), inciphise isantya sesithuthi (esifana ne-80km/h) kwaye ikhubaze eminye imisebenzi, nto leyo ekhokelela ekukhawuleziseni okubuthathaka kunye nobunzima bokunyuka amathambeka.
Iimpawu eziqhelekileyo ezibangelwa kukungasebenzi kakuhle
Emva kokuba i-sensor yendawo ye-camshaft yonakele, imoto iya kubonisa ngoko nangoko ezi zinto zilandelayo, eziqinisekisa ngakumbi ukuba akunakwenzeka ukuqhuba:
I-Youdaoplaceholder0 Isantya esingazinzanga sokungaqhubi kakuhle kunye nokushukuma okukhulu : I-ECU iyasilela ukulungelelanisa ixesha lokuvulwa nokuvalwa kwevalvu, nto leyo ebangela ukungalingani phakathi komthamo wokungenisa kunye nokukhupha umoya. Injini ikwimeko efana "nesilinda esingekhoyo", kunye nokuguquguquka okukhulu kwisantya sokujikeleza.
I-Youdaoplaceholder0 Ukuwohloka kokusetyenziswa kwepetroli: Ixesha elingachanekanga lokufakwa kwepetroli likhokelela ekutshisweni okungaphelelanga, okunyusa ukusetyenziswa kwepetroli nge-10% ukuya kwi-15%, kwaye umsi omnyama ungaphuma kumbhobho wokukhupha umoya ngaxeshanye.
Isibane sempazamo sihlala sivuliwe: ideshibhodi iya kubonisa isilumkiso sempazamo yenjini (esifana nekhowudi P0011 okanye P0340), esibonisa ingxaki yenkqubo.
Umngcipheko wokuqhuba ngenkani
Ukuba ukungasebenzi kakuhle akunanzwa kwaye imoto iyaqhubeka nokuqhuba, iziphumo ezilandelayo ezibi zinokwenzeka
Umonakalo woomatshini wenjini ye-Youdaoplaceholder0 : Ixesha elingalunganga lokutsha linokubangela ukugoba okanye ukuguquka kwe-crankshaft. Ukusebenza ixesha elide kunokonakalisa izinto eziphambili ezifana neepiston kunye neentonga zokudibanisa, nto leyo enyusa kakhulu iindleko zokulungisa.
Ukusilela kwenkqubo yokukhupha umbane ye-Youdaoplaceholder0: Ukutsha okungaphelelanga kubangela ukukhutshwa okugqithisileyo kwe-CO kunye ne-HC, okunokuthi kuvale i-catalytic converter eneendlela ezintathu kwaye kwaphule imigaqo yokhuseleko lokusingqongileyo.
Ingozi zokhuseleko zeYoudaoplaceholder0 ziyanda: Ukuma okanye ukuphazamiseka kwamandla ngelixa uqhuba kunokuchaphazela ngokuthe ngqo iinkqubo ezifana ne-brake assist kunye ne-steering assist, nto leyo ebeka umngcipheko kukhuseleko lokuqhuba.
