Yintoni umsebenzi weplagi yesenzi sobushushu bamanzi emotweni
I-sensor yobushushu bamanzi emoto (isensor yobushushu bamanzi) idlala indima ebalulekileyo emotweni, iindima eziphambili ziquka ezi zilandelayo:
Ukuchonga ubushushu be-coolant: Iplagi yesenzi sobushushu bamanzi inoxanduva lokulinganisa ubushushu be-coolant ngexesha langempela, nto leyo ibalulekileyo kwinkqubo yokufudumeza ngexesha lokuqala kokubanda. Ijonga utshintsho lobushushu ukuze ilawule isantya sefeni xa kuyimfuneko kwaye ide ichaphazele nokuseta isantya sokungenzi nto ukuze isebenze kakuhle kwaye isebenzise kakuhle ipetroli.
Ukulungiswa kwe-fuel injection : Ngokubona ubushushu be-coolant, iplagi yesenzi sobushushu bamanzi inika isignali yokulungisa inkqubo ye-fuel injection ukuqinisekisa ukufakwa kwe-fuel ngokuchanekileyo, kuthintelwe ubushushu bokutsha obuphezulu kakhulu okanye obuphantsi kakhulu, ngaloo ndlela kukhusela injini kwaye kuphuculwe ukonga kwe-fuel .
Bonisa ulwazi lobushushu bamanzi: Ibonelela ngokufundwa kwangethuba kwegeyiji yobushushu bamanzi yesithuthi ukuze umqhubi akwazi ukuqonda imeko yokusebenza kwenjini aze athathe amanyathelo ngexesha elifanelekileyo ukugcina ukusebenza kakuhle.
Ukulungiswa kwexesha lokutsha: isignali yobushushu be-coolant efunyenwe yiplagi yesenzi sobushushu bamanzi iya kusetyenziselwa ukulungisa ixesha lokutsha ukuqinisekisa imeko yokusebenza engcono kakhulu yenjini kumaqondo obushushu ahlukeneyo.
Umgaqo osebenzayo weplagi yokuva ubushushu bamanzi usekelwe kwiimpawu zayo zangaphakathi ze-thermistor. Ixabiso lokumelana le-thermistor liyatshintsha ngobushushu, kwaye iplagi yesenzi sobushushu bamanzi iguqula olu tshintsho lube yisignali yombane kwaye iyithumele kwiyunithi yolawulo lwe-elektroniki (ECU). I-ECU ilungisa ixesha lokujova, ixesha lokutsha kunye nolawulo lwefeni ngokwesignali efunyenweyo, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lwenjini .
Iintlobo ezahlukeneyo zeeplagi zokuva ubushushu bamanzi ziquka intambo enye, intambo ezimbini, intambo ezintathu kunye nentambo ezine. Zahlukile kuyilo kunye nomsebenzi kwaye zihlala zifakelwa kwiindawo ezibalulekileyo zenkqubo yokupholisa, njengakufutshane nentloko yesilinda, ibhloko kunye ne-thermostat.
Xa iplagi yesenzi sobushushu bamanzi emoto yonakele, kuya kuvela ezi mpawu zilandelayo:
Isilumkiso sephaneli yesixhobo: Xa iplagi yesenzi sobushushu bamanzi inempazamo, isalathisi esifanelekileyo kwiphaneli yesixhobo sinokukhazimla okanye siqhubeke nokukhanya njengesilumkiso senkqubo.
Ukufundwa kobushushu obungaqhelekanga : Ubushushu obuboniswa kwi-thermometer abuhambelani nobushushu bokwenyani. Ngenxa yoko, isalathisi se-thermometer sisenokungashukumi okanye singakhombisi kwindawo ephezulu yobushushu.
Ubunzima bokuqalisa ngokubanda: Ngexesha lokuqalisa ukubanda, i-ECU ayikwazi ukubonelela ngolwazi oluchanekileyo loxinzelelo lomxube ngenxa yokuba isensa ayichazi kakuhle imeko yokuqalisa okushushu, nto leyo eyenza ukuqala kokubanda kube nzima.
Ukwanda kokusetyenziswa kwepetroli kunye nesantya esingaguqukiyo sokungaqhubi kakuhle: Izinzwa ezingalunganga zinokuchaphazela ulawulo lwe-ECU lokujova ipetroli kunye nexesha lokutsha, okubangela ukwanda kokusetyenziswa kwepetroli kunye nesantya esingaguqukiyo sokungaqhubi kakuhle.
Ukuhla kokusebenza kwesantya: nokuba i-throttle epheleleyo, isantya senjini asinakonyuswa, nto leyo ebonisa ukungabikho kwamandla okucacileyo.
Umgaqo wokusebenza kunye nokubaluleka kweplagi yesenzi sobushushu bamanzi: ngokujonga ubushushu bamanzi apholisayo enjinini, ulwazi lobushushu luguqulwa lube sisignali yombane kunye nemveliso eya kwiyunithi yolawulo lwe-elektroniki, ukuze kulawulwe ngokuchanekileyo ubungakanani bokufakwa kwepetroli, ixesha lokutsha kunye nezinye iiparameter ezibalulekileyo. Ikwachaphazela ukusebenza kwezinto ezifana nevalvu yokulawula engasebenziyo ukuqinisekisa ukusebenza okuqhelekileyo kwenjini.
Indlela yokujonga nokutshintsha: Sebenzisa i-multimeter ukuvavanya isenzi sobushushu bamanzi. Fudumeza isenzi kwaye ujonge utshintsho lokumelana ukuze ubone ukuba ilungile okanye ayilunganga. Ukongeza, ukusebenzisa isixhobo sokuchonga iimpazamo ukujonga ukuba kukho ikhowudi yempazamo kwimeko yokubanda kukwayindlela esebenzayo yokufumanisa. Nje ukuba impazamo ifunyenwe, kufuneka itshintshwe ngexesha ukuqinisekisa ukusebenza okuqhelekileyo kwenjini.
