Umsebenzi wenzwa yoxinzelelo lwemoto
Ukubeka iliso kuxinzelelo oluphindaphindiweyo
Inzwa yoxinzelelo lokuthatha iqhagamshelwe kwi-intake manifold ngokusebenzisa ityhubhu yokufunxa ukufumanisa utshintsho olupheleleyo loxinzelelo kwi-manifold intake emva kwevalve ye-throttle ngexesha langempela. Olu tshintsho loxinzelelo luhambelana ngokusondeleyo kunye nesantya kunye nomthwalo we-injini, kwaye ii-sensor ziguqula ezi zinguqu zemishini kwiimpawu zombane ezithunyelwa kwi-ECU.
Lungiselela inaliti yamafutha
Ngokusekelwe kwisignali yoxinzelelo olunikezwa yinzwa, i-ECU ibala ngokuchanekileyo inani lamafutha afunwa yi-injini. Xa umthwalo we-injini usanda, uxinzelelo lwe-intake manifold luyancipha, i-sensor output signal iyanda, kwaye i-ECU yonyusa umthamo we-injection ye-fuel ngokufanelekileyo. Ngaphandle koko, iya kuncipha. Olu lungelelaniso oluguquguqukayo luqinisekisa ukusebenza kakuhle kwe-injini phantsi kweemeko ezahlukeneyo zokusebenza.
Lawula ixesha lokucima
Inzwa yoxinzelelo lokuthatha iphinda incede i-ECU ilungise ixesha lokutshisa. Xa umthwalo we-injini usanda, i-engile yokulayita kwangaphambili iya kulibaziseka ngokufanelekileyo. Xa umthwalo uncitshisiwe, i-Angle yokutshisa kwangaphambili iya phambili. Olu hlengahlengiso lunceda ukuphucula ukusebenza kwamandla enjini kunye noqoqosho lwamafutha.
Ubalo lokuhamba komoya oluncedisayo
Kwinkqubo ye-injection ye-fuel ye-Type D, i-sensor yoxinzelelo lwe-intake isetyenziswe ngokubambisana nemitha yokuhamba komoya ukulinganisa umthamo wokungena ngokungathanga ngqo, ngaloo ndlela ubala ukuhamba komoya ngokuchanekileyo. Lo msebenzi wentsebenziswano uqhubela phambili ukongeza ukutofa kwamafutha kunye nokusebenza kwe-injini.
Ukufunyanwa kwempazamo kunye nokhuseleko
I-sensor yoxinzelelo lwe-intake iyakwazi ukubona utshintsho olungaqhelekanga kwi-manifold intake, njengama-clogs okanye ukuvuza, kunye nokuthumela iimpawu kwi-ECU. Oku kunceda ukubona ukusilela kwe-injini ngexesha kwaye uthathe amanyathelo okukhusela ukuphepha umonakalo ongakumbi.
Iintlobo kunye nemigaqo yokusebenza
Izinzwa zoxinzelelo oluqhelekileyo lokuthatha ziquka i-varistor kunye neentlobo ze-capacitive. I-sensor ye-varistor itshintsha ukuchasana ngokuguqulwa kwe-silicon diaphragm kwaye ikhupha umqondiso wombane. I-sensor ye-capacitive itshintsha ixabiso le-capacitance ngokusebenzisa i-deformation ye-diaphragm kunye neziphumo zesignali ye-pulse. Zombini izinzwa zisetyenziswa ngokubanzi kwizithuthi zanamhlanje ngokuchaneka kwazo okuphezulu kunye nokuphendula ngokukhawuleza.
Shwankathela
Inzwa yoxinzelelo lwe-intake yenye yezona zinto ziphambili zenkqubo yokulawula injini yemoto, indima yayo ayipheleli nje ekubekeni iliso kuxinzelelo, kodwa ikwabandakanyeka kwi-injection yepetroli, ixesha lokutshisa, ukubala ukuhamba komoya kunye nokufumanisa impazamo. Ngokulawula ngokuchanekileyo ezi parameters, abenzi boluvo baphucula kakhulu ukusebenza kwe-injini, uqoqosho lwamafutha kunye nokukhutshwa.
I-Automotive intake sensor sensor (i-intake pressure sensor) yenye yezinto eziphambili zenkqubo ye-injection ye-fuel, ukungaphumeleli kwayo kuya kubangela ukuba iyunithi yokulawula injini (ECU) ayikwazi ukulungelelanisa ngokuchanekileyo umlinganiselo we-air-fuel. Ezi zilandelayo zezona mpawu ziphambili kunye noonobangela bempazamo:
Iimpawu eziphambili zokubonisa
Ubunzima okanye ukungakwazi ukuqalisa injini
Iimpawu zesivamvo esingaqhelekanga ziya kubangela ukuba i-ECU ingaphumeleli ukubala isixa esichanekileyo sokutofa amafutha, okuchaphazela ngokuthe ngqo ukutshisa kunye nenaliti yamafutha.
Ukuba umgca we-sensor uphukile okanye ufutshane, i-ECU inokulahlekelwa ngokupheleleyo kwidatha yokunyanzeliswa kokuthatha, okubangela ukuhluleka kokuqala.
Ukukhutshwa kwamandla okungaqhelekanga
Ukukhawuleza okungahambi kakuhle okanye ukuhla kwamandla : inzwa ayikwazi ukulungelelanisa isignali kunye nokutshintsha kweqondo le-vacuum, kwaye i-ECU ibala kakubi ukungena komoya, okubangelwa ukuphambuka kobuninzi benaliti yeoli.
isantya esingaqhelekanga sokungenzi nto : Xa umxube ungqindilili kakhulu okanye ubhityile kakhulu, i-injini inokungcangcazela okanye isantya sokuguquguquka.
ukutshisa okungaqhelekanga
Umsi omnyama ophuma kumbhobho wokukhupha : umxube ungqindilili kakhulu ukuba ubangele ukutsha okungaphelelanga, okubonwa ngokukhawulezileyo ngokukhawuleza.
Ubushushu bombhobho wokuthatha : Xa umxube ubhityile kakhulu, irhasi engatshiyo iyatshisa kumbhobho wokuthatha.
Ukuhlelwa kwesizathu esinempazamo
Inzwa ngokwayo
Igeyiji yoxinzelelo lwangaphakathi okanye ukusilela kwesekethe (umzekelo, ukusilela kwegeyiji yoxinzelelo lwesemiconductor).
Umbane wesiginali yemveliso udlula uluhlu oluqhelekileyo (olufana ne-voltage drift).
ukusilela okunxulumene nangaphandle
I-vacuum hose ivaliwe okanye ivuza, echaphazela ukuhanjiswa koxinzelelo.
Ukufakwa ngokungafanelekanga kwendandatho yesitywina kukhokelela ekuthinteleni i-inlet yoxinzelelo (ukuguqulwa kwesignali ngexesha loxinzelelo).
Isiphakamiso sokuxilonga
Uviwo lokuqala
Qaphela ukuba isibane sempazamo sivuliwe (ezinye iimodeli ziya kubangela ikhowudi yempazamo ye-OBD).
Jonga udibaniso lombhobho wokufutha kunye nentambo yokubopha iingcingo zoluvo.
Uvavanyo lobuchwephesha
Sebenzisa i-diagnostics ukufunda imijelo yedatha yexesha langempela kwaye uthelekise amaxabiso oxinzelelo oluqhelekileyo.
Vavanya ukuba ingaba i-voltage ye-sensor output iyahluka ngokuvuleka kwe-throttle.
ingcebiso : Ukuba ezi mpawu zingentla zikhatshwa ziikhowudi eziphosakeleyo (ezifana ne-P0105/P0106), inzwa kunye neesekethe ezinxulumene nazo kufuneka zihlolwe kuqala. Ukungahoywa kwexesha elide kunokubangela umonakalo kwi-converter ye-catalytic yeendlela ezintathu okanye ukunyuka okukhulu kokusetyenziswa kwamafutha.
