Umsebenzi wenzwa yoxinzelelo lwemoto
Imisebenzi ephambili ye-automotive air intake sensor sensor ibandakanya le miba ilandelayo:
Ukubonelela ngesignali yomthwalo we-injini : Inzwa yoxinzelelo lwe-intake inikezela ngesignali yomthwalo we-injini kwi-ECU (iyunithi yokulawula injini) ngokulinganisa utshintsho loxinzelelo kwi-manifold intake. Le miqondiso inceda i-ECU ilawule ngokuchanekileyo ububanzi benaliti ye-pulse kunye nokuvulwa kwe-throttle ukuze kuphuculwe ukusebenza kwe-injini kunye noqoqosho lwamafutha.
Lawula inaliti yamafutha kunye nexesha lokutshisa : Iinzwa ziguqula utshintsho loxinzelelo kwindawo eninzi yokuthatha ibe ziimpawu zombane ze-ECU ukulungisa inaliti yamafutha kunye ne-Angle yexesha lokutshisa. Xa umthwalo we-injini usanda, uxinzelelo kwi-intake manifold luyancipha, isibonakaliso sokuphuma kwenzwa siyenyuka, kwaye i-ECU yonyusa inani le-injection ye-fuel kunye nokulibazisa i-Angle yokutshisa kwangaphambili. Ngaphandle koko, inaliti yamafutha iya kuncitshiswa kwaye ukutshisa kuya kuba phambili.
Lungisa ixesha lokuvula i-valve yokungena kunye ne-injection ye-fuel : Kwi-injini enenkqubo yokulawula i-valve ye-elektroniki, i-sensor yoxinzelelo lwe-intake ibona utshintsho loxinzelelo kumbhobho wokuthatha kwaye ibale ngokuchanekileyo umthamo womoya kwi-cylinder nganye ukulungelelanisa ixesha lokuvula i-valve yokungena kunye nomthamo we-injection ye-fuel. Oku kunceda ukuphucula ukusebenza kakuhle kunye nokukhutshwa kwamandla enjini.
khusela i-injini : Inzwa yoxinzelelo lwe-intake inokubona iimeko ezingaqhelekanga zokusebenza ze-injini, ezinjengokutshintsha koxinzelelo olungaqhelekanga, kunye nokuthumela imiqondiso kwinkqubo yokulawula ukukhusela injini. Oku kunceda ukuthintela umonakalo we-injini ngenxa yokugcwala okanye eminye imiba.
Umgaqo wokuSebenza : Isivamvo soxinzelelo lokuthatha sihlala siqhagamshelwa kwi-intake manifold ngetyhubhu yevacuum kwaye iziva utshintsho lwevacuum kwindawo eninzi yokuthatha. Njengoko isantya se-injini kunye nomthwalo utshintsha, uxinzelelo kwi-intake manifold luya kutshintsha, kwaye ukuchasana ngaphakathi kwe-sensor kuya kutshintsha ngokufanelekileyo, ngaloo ndlela kuphuma umqondiso wombane. Lo mqondiso ufunyenwe yi-ECU kwaye isetyenziselwa ukulungelelanisa inaliti yamafutha kunye nexesha lokutshisa.
Impembelelo yempazamo : Ukuba i-sensor yoxinzelelo lwe-intake yonakalisiwe, inokukhokelela kwisantya esingazinzanga esingasebenziyo, ukukhawuleza obuthathaka, ubunzima ekuqaliseni, ukunyuka kokusetyenziswa kwamafutha kunye nezinye iingxaki zesithuthi. Ngexesha elifanayo, ukukhanya kwe-injini kuya kukhanya, kwaye ikhowudi yephutha ehambelana nayo iya kugcinwa.
Ngoko ke, ukuhlolwa rhoqo kunye nokugcinwa kwenzwa yoxinzelelo lokuthatha kubalulekile ukuqinisekisa ukusebenza okuqhelekileyo kwesithuthi.
I-Manifold Absolute Pressure Sensor (MAP) licandelo elibalulekileyo kwi-injini yemoto ebeka esweni utshintsho loxinzelelo kwi-manifold yokuthatha kwaye iguqule olu tshintsho lube yimiqondiso yombane yolawulo oluchanekileyo yiyunithi yolawulo lwe-elektroniki ye-injini (ECU). Isivamvo soxinzelelo lwe-intake sidityaniswe kuninzi lokuthatha ngetyhubhu yevacuum kwaye sinokuluva utshintsho lwevacuum kwindlela yokuthatha. Ngesantya se-injini esahlukileyo kunye nomthwalo, ukuchasana ngaphakathi kwenzwa kuya kutshintsha, okuya kuguqulwa kube ngumqondiso we-voltage ye-ECU ukulungisa inani le-injection ye-fuel kunye nexesha lokucima.
Umgaqo wokusebenza
Umgaqo wokusebenza we-sensor yoxinzelelo lwe-intake isekelwe kwinguqu yokuchasana ebangelwa utshintsho loxinzelelo. Thatha i-varistor type inlet inlet sensor njengomzekelo, icandelo layo eliphambili yi-silicon diaphragm eyenziwe ngempembelelo ye-piezoresistive ye-semiconductor. Xa uxinzelelo lwe-manifold intake lusebenza kwi-silicon diaphragm, i-diaphragm iya kuguqulwa, ibangele utshintsho kwixabiso layo lokumelana. Olu tshintsho luguqulwa lube ngumqondiso wombane, okhuliswe kwaye udluliselwe kwi-ECU. Ngokusekwe kumbane wophawu olufunyenweyo, iECU ilawula ngokuchanekileyo inaliti yamafutha esisiseko ukuze ihambelane neemfuno ezahlukeneyo zokuqhuba.
Iintlobo kunye nezicelo
Zininzi iindidi zezivamvo zoxinzelelo lokuthatha, ezo ziqhelekileyo zii-semiconductor varistor, ivacuum bellows kunye ne-capacitive. Phakathi kwabo, i-semiconductor varistor isetyenziswa ngokubanzi kwi-D-type injection system ngenxa yeenzuzo zayo zokuphendula ngokukhawuleza, ukuchaneka okuphezulu, ubungakanani obuncinci kunye nofakelo oluguquguqukayo. I-sensor ye-capacitive isebenzisa i-diaphragm ukwenza into enobunzima boxinzelelo kunye nexabiso le-capacitance eguquguqukayo, kwaye iguqula utshintsho loxinzelelo lube ngumqondiso wombane ngokulinganisa isiphaluka.
Ukugcinwa kunye nokuxilongwa kweempazamo
Ukuxilongwa kwesiphoso senzwa yoxinzelelo lokuthatha ngokuqhelekileyo kubandakanya ukujonga ukuba isignali yayo yokuphuma ingaphakathi koluhlu oluqhelekileyo. Ukuba isignali yokukhupha inzwa ayiqhelekanga, ukusebenza kwe-injini kunokuthotywa okanye ukungazinzi. Ngexesha lokugcinwa, jonga rhoqo uqhagamshelo kunye nokutywinwa kwenzwa ukuqinisekisa ukuba isebenza ngokufanelekileyo.
