Yintoni umsebenzi weplagi yobushushu bamanzi emoto
Inzwa yobushushu bamanzi emoto (inzwa yobushushu bamanzi) idlala indima ephambili emotweni, iindima eziphambili ziquka oku kulandelayo:
Ukufunyaniswa kobushushu obupholileyo : Iplagi yesivamvo seqondo lobushushu bamanzi inoxanduva lokulinganisa ubushushu bexesha langempela lokupholisa, oluyimfuneko kwinkqubo yokufudumala ngexesha lokuqalisa kwengqele. Ibeka iliso kutshintsho lweqondo lobushushu ukuze ilawule isantya sefeni xa kuyimfuneko kwaye ide ibe nefuthe ekusekweni kwesantya sokungenzi nto ukuze isebenze kakuhle kunye nokusebenza kakuhle kwamafutha.
Ukulungiswa kwenaliti ye-Fuel : Ngokubona iqondo lobushushu elipholileyo, iplagi yenzwa yobushushu bamanzi ibonelela ngophawu lolungiso lwenkqubo yokutofa ngamafutha ukuze kuqinisekiswe inaliti yamafutha echanekileyo, ukuthintela ubushushu obuphezulu kakhulu okanye obuphantsi kakhulu, ngaloo ndlela ikhusela injini kunye nokuphucula uqoqosho lwamafutha.
Bonisa ulwazi lobushushu bamanzi : Ibonelela ngokufunda kwangexesha lokwenyani lokulinganisa ubushushu bamanzi esithuthi ukuze umqhubi aqonde imeko yokusebenza kwe-injini kwaye athathe inyathelo kwangexesha ukugcina ukusebenza kakuhle.
Ulungiso lwexesha lokutshisa : uphawu lweqondo lobushushu lokupholisa elifunyenwe yiplagi yesivamvo sobushushu bamanzi liya kusetyenziswa ukulungisa ixesha lokulayita ukuqinisekisa eyona meko ingcono yokusebenza kwenjini kumaqondo obushushu ahlukeneyo.
Umgaqo osebenzayo weplagi yokuva ubushushu bamanzi isekelwe kwiipropati zayo zangaphakathi ze-thermistor. Ixabiso lokumelana nokutshintsha kwe-thermistor kunye neqondo lokushisa, kwaye iplagi ye-sensor yeqondo lokushisa kwamanzi iguqula le nguqu ibe ngumqondiso wombane kwaye iyithumele kwiyunithi yokulawula i-electronic (ECU). I-ECU ihlengahlengisa ixesha lokutofa, ixesha lokutshisa kunye nolawulo lwabalandeli ngokwesiginali efunyenweyo, ngaloo ndlela iqonda ulawulo oluchanekileyo lwe-injini.
Iindidi ezahlukeneyo zeeplagi zokuva ubushushu bamanzi ziquka umgca omnye, ucingo olumbini, ucingo oluthathu kunye nocingo olune. Ziyahluka kuyilo kunye nomsebenzi kwaye zivame ukufakwa kwiindawo eziphambili zenkqubo yokupholisa, ezifana kufuphi nentloko ye-cylinder, ibhloko kunye ne-thermostat.
Xa iplagi yobushushu bamanzi emoto yonakele, ezi mpawu zilandelayo ziya kuvela:
Isilumkiso sepaneli yesixhobo : Xa iplagi yenzwa yobushushu bamanzi iphosakele, isalathisi esifanelekileyo kwipaneli yesixhobo sinokuqhwanyaza okanye siqhubeke nokukhanya njengesignali yesilumkiso senkqubo. ...
Ukufundwa kobushushu obungaqhelekanga : Iqondo lobushushu eliboniswe kwithemometha alihambelani neqondo lokwenene. Ngenxa yoko, isalathisi se-thermometer sinokungashukumi okanye sibhekise kwindawo ephezulu yobushushu. ...
Ubunzima bokuqalisa okubandayo : Ngexesha lokuqalisa okubandayo, i-ECU ayikwazi ukubonelela ngolwazi oluchanekileyo lokuxinanisa umxube ngenxa yesivamvo esichaza kakubi isimo sokuqala esishushu, esenza ukuba ukuqalisa okubandayo kube nzima.
Ukonyuka kokusetyenziswa kwepetroli kunye nesantya sokungasebenzi kakuhle : Izinzwa ezingalunganga zinokuchaphazela ulawulo lwe-ECU lwenaliti yamafutha kunye nexesha lokutshisa, okukhokelela ekonyukeni kokusetyenziswa kwepetroli kunye nesantya esingaqhelekanga sokungenzi nto.
Ukwehla kokusebenza kwe-Acceleration : nakwimeko ye-throttle epheleleyo, isantya se-injini asikwazi ukunyuswa, kubonisa ukungabikho kwamandla okucacileyo.
Umgaqo osebenzayo kunye nokubaluleka kweplagi yenzwa yokushisa kwamanzi: ngokubeka iliso kwiqondo lokushisa kwamanzi okupholisa injini, ulwazi lweqondo lokushisa luguqulwa lube ngumqondiso wombane kunye nokuphuma kwiyunithi yokulawula i-electronic control unit, ukwenzela ukulawula ngokuchanekileyo inani le-injection ye-fuel, ixesha lokucima kunye nezinye iiparitha eziphambili. Kwakhona kuchaphazela umsebenzi wamacandelo afana ne-valve yokulawula i-idle ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini. ...
Jonga kunye nendlela yokutshintsha : Sebenzisa i-multimeter ukuvavanya inzwa yobushushu bamanzi. Fudumeza inzwa kwaye ujonge utshintsho lokuchasana ukujonga ukuba kulungile okanye kubi. Ukongezelela, ukusetyenziswa kwesixhobo sokuxilongwa kwephutha ukujonga ukuba kukho ikhowudi yephutha kwimeko ebandayo nayo yindlela esebenzayo yokufumanisa. Xa impazamo ifunyenwe, kufuneka itshintshwe kwangethuba ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwe-injini.
