Umsebenzi we-sensor yoxinzelelo lokungenisa iimoto
Jonga uxinzelelo oluninzi lokungenisa
I-input pressure sensor iqhagamshelwe kwi-input manifold nge-vacuum tube ukuze ibone utshintsho olupheleleyo loxinzelelo kwi-input manifold engasemva kwevalvu ye-throttle ngexesha langempela. Olu tshintsho loxinzelelo lunxulumene kakhulu nesantya kunye nomthwalo wenjini, kwaye ii-sensors ziguqula olu tshintsho loomatshini lube ziimpawu zombane ezithunyelwa kwi-ECU.
Lungiselela i-fuel injection
Ngokusekelwe kwisignali yoxinzelelo enikwa yi-sensor, i-ECU ibala ngokuchanekileyo ubungakanani bepetroli efunekayo yinjini. Xa umthwalo wenjini unyuka, uxinzelelo lwe-intake manifold luyehla, isignali yokukhupha i-sensor iyanda, kwaye i-ECU inyusa umthamo we-injection fuel ngokufanelekileyo. Ngaphandle koko, iya kuncipha. Olu hlengahlengiso oluguquguqukayo luqinisekisa ukusebenza kakuhle kwenjini phantsi kweemeko ezahlukeneyo zokusebenza.
Ixesha lokulawula ukutsha
Isixhobo sokuvavanya uxinzelelo lokungenisa ikwanceda i-ECU ukuba ilungise ixesha lokutsha. Xa umthwalo wenjini unyuka, i-Angle ye-inflating advance iya kulibaziseka ngokufanelekileyo. Xa umthwalo uncitshisiwe, i-Angle ye-inflating advance iya kutsha. Olu hlengahlengiso lunceda ukuphucula ukusebenza kwamandla enjini kunye nokonga amafutha.
Ukubalwa kokuhamba komoya okuncedisayo
Kwinkqubo yokufaka amafutha yohlobo lwe-D, i-input pressure sensor isetyenziswa kunye ne-air flow meter ukulinganisa umthamo wokungenisa ngokungathanga ngqo, ngaloo ndlela kubalwa ukuhamba komoya ngokuchanekileyo. Lo msebenzi wokubambisana uphucula ngakumbi i-fuel injection kunye nokusebenza kwenjini.
Ukufunyanwa nokukhuselwa kwempazamo
I-intake pressure sensor iyakwazi ukubona utshintsho olungaqhelekanga kuxinzelelo kwi-intake manifold, njengokuvaleka okanye ukuvuza, kwaye ithumele imiqondiso kwi-ECU. Oku kunceda ukubona ukungasebenzi kakuhle kwenjini ngexesha kwaye kuthathe amanyathelo okuzikhusela ukuze kuthintelwe umonakalo ongakumbi.
Iintlobo kunye nemigaqo yokusebenza
Iisensa zoxinzelelo lokungenisa umoya eziqhelekileyo ziquka iintlobo ze-varistor kunye ne-capacitive. Isensa ye-varistor itshintsha ukumelana ngokuguqulwa kwe-silicon diaphragm kwaye ikhuphe isignali yombane. Isensa ye-capacitive itshintsha ixabiso le-capacitance ngokuguqulwa kwe-diaphragm kwaye ikhuphe isignali ye-pulse. Zombini ezi sensa zisetyenziswa kakhulu kwizithuthi zanamhlanje ngenxa yokuchaneka kwazo okuphezulu kunye nokuphendula ngokukhawuleza.
Shwankathela
Isenzi soxinzelelo lokungenisa umoya yenye yezona zinto ziphambili kwinkqubo yokulawula injini yeemoto, indima yaso ayipheleli nje ekujongeni uxinzelelo, kodwa ikwabandakanyeka ekufakweni kwepetroli, ixesha lokutsha, ukubalwa kokuhamba komoya kunye nokuchongwa kweempazamo. Ngokulawula ngokuchanekileyo ezi parameters, izisenzi ziphucula kakhulu ukusebenza kwenjini, ukonga amafutha kunye nokukhutshwa komoya.
I-sensor yoxinzelelo lokungenisa iimoto (i-sensor yoxinzelelo lokungenisa) yenye yezona zinto ziphambili kwinkqubo yokufaka amafutha, ukusilela kwayo kuya kubangela ukuba iyunithi yokulawula injini (ECU) ingakwazi ukulungisa ngokuchanekileyo umlinganiselo womoya-fuel. Ezi zilandelayo ziimpawu eziphambili kunye nezizathu zempazamo:
Ukubonakaliswa kweempawu eziphambili
Ubunzima okanye ukungakwazi ukuqalisa injini
Imiqondiso yenzwa engaqhelekanga iya kubangela ukuba i-ECU ingabalanga ubungakanani obuchanekileyo bokufakwa kwepetroli, nto leyo echaphazela ngokuthe ngqo ukutsha kunye nokufakwa kwepetroli.
Ukuba umgca wesenzi wombane waphukile okanye ufutshane, i-ECU inokulahlekelwa ngokupheleleyo yidatha yoxinzelelo lokungenisa, nto leyo ekhokelela ekusileleni kokuqala.
Ukuphuma kwamandla okungaqhelekanga
ukukhawulezisa okungekho semgangathweni okanye ukuhla kwamandla: i-sensor ayikwazi ukulungisa isignali ngokutshintsha kweqondo lokukhupha umoya, kwaye i-ECU ibala kakubi indlela umoya ongenayo ngayo, nto leyo ebangela ukuphambuka kobungakanani bokufakwa kweoyile.
isantya esingaguqukiyo sokungaqhubi kakuhle : Xa umxube utyebile kakhulu okanye ubhityile kakhulu, injini isenokushukuma okanye itshintshe isantya.
ukungaqheleki kokutsha
Umsi omnyama ovela kumbhobho wokukhupha umoya: umxube utyebile kakhulu ukuba ungabangela ukutsha okungaphelelanga, okubonakala rhoqo ekukhawuleziseni ngokukhawuleza.
Ukufudumala kombhobho wokungenisa: Xa umxube ubhityile kakhulu, igesi engatshiyo iyavutha kumbhobho wokungenisa.
Uhlu lwezizathu zempazamo
Isensor ngokwayo
I-internal strain gauge okanye i-circuit failure (umz. i-semiconductor strain gauge failure).
I-voltage yesignali yesiphumo idlula uluhlu oluqhelekileyo (njengokushukuma kwe-voltage).
ukusilela okunxulumeneyo kwangaphandle
Umbhobho wevacuum uvaliwe okanye uyavuza, nto leyo echaphazela ukudluliselwa koxinzelelo.
Ukufakwa okungafanelekanga kweringi yokutywina kukhokelela ekuvalekeni kwendawo yokungena koxinzelelo (ukuguqulwa kwesignali ngexesha loxinzelelo).
Ingcebiso yokuxilonga
Uvavanyo lwangaphambili
Jonga ukuba isibane sempazamo sivuliwe na (ezinye iimodeli ziya kuqalisa ikhowudi yempazamo ye-OBD).
Jonga uqhagamshelo lwepayipi ye-vacuum kunye ne-sensor wiring harness.
Uvavanyo lobuchwephesha
Sebenzisa uxilongo ukuze ufunde imithombo yedatha yexesha langempela kwaye uthelekise amaxabiso aqhelekileyo oxinzelelo.
Vavanya ukuba i-voltage ye-sensor output iyahluka na ngokwe-throttle open.
Icebiso: Ukuba ezi mpawu zingasentla zihamba neekhowudi zempazamo (ezifana ne-P0105/P0106), i-sensor kunye neesekethe ezinxulumene nayo kufuneka zihlolwe kuqala. Ukungahoywa kwexesha elide kunokubangela umonakalo kwi-catalytic converter yeendlela ezintathu okanye ukwanda okukhulu kokusetyenziswa kwepetroli.
