Isixhobo Sokubona Ubushushu Bamanzi Enjinini: Umlindi Wobushushu Benjini Nokuchongwa Kweziphene
Kwinkqubo yokusebenza ngokuchanekileyo kwenjini yemoto, isenzi sobushushu bamanzi sisebenza njengomkhuseli othuleyo wobushushu, sihlala sijonga ubushushu be-coolant yenjini kwaye sikhusela ukusebenza okuzinzileyo kwenjini. Nangona incinci ngobukhulu, idlala indima engenakutshintshwa kulawulo lokusebenza kwenjini kunye nokuqinisekisa ukonga amafutha. Xa isenzi sobushushu bamanzi singasebenzi kakuhle, siya kuzisa iingozi ezininzi ezinokubakho ekusebenzeni kwesithuthi, nto leyo efuna umnini ukuba ayibone aze ayiphathe ngexesha.
Umsebenzi oPhambili weSensor yoBushushu bamanzi eNjini
I-sensor yobushushu bamanzi, eyaziwa ngokuba yi-sensor yobushushu bamanzi, iguqula utshintsho lobushushu lwe-coolant lube ziimpawu zombane ngokusebenzisa izinto zayo zangaphakathi ze-thermistor kwaye izithumele kwiyunithi yolawulo lwesithuthi ukuze kufezekiswe ulawulo oluchanekileyo lwenjini. Imisebenzi yayo ephambili ibonakala kakhulu kwezi zinto zilandelayo:
Okokuqala, ijonga ubushushu be-coolant ngexesha langempela ukuqinisekisa ubushushu obusebenzayo obuzinzileyo benjini. Kuphela xa injini isebenza ngaphakathi komgangatho wobushushu ofanelekileyo apho inokuthi isebenze ngokufanelekileyo. I-sensor yobushushu bamanzi inokubamba utshintsho lobushushu be-coolant ngexesha langempela. Ngexesha lokuqala kokubanda, iya kudlulisela isignali yobushushu obuphantsi kwiyunithi yolawulo, kwaye iyunithi yolawulo iya kulungisa isantya sefeni kwaye yonyuse isantya sokungaqhubi ukuze ikhawulezise inkqubo yokufudumeza injini, ivumele injini ukuba ingene kwimeko yokusebenza efanelekileyo ngokukhawuleza; xa ubushushu benjini buphezulu kakhulu, iya kubangela ifeni ukuba isebenze ngesantya esiphezulu ukuze ipholise injini ngokukhawuleza, ithintele ukuguguleka okukhawulezileyo kunye nokonakala kwezinto ngenxa yobushushu obugqithisileyo.
Okwesibini, ilungisa ixesha lokufakwa kwepetroli kunye nexesha lokutsha, iphucula ukonga kwamafutha kunye nokusebenza kwamandla. Isignali yobushushu edluliselwa sisivamvo sobushushu bamanzi sisalathiso esibalulekileyo kwinkqubo yokufaka ipetroli kunye nenkqubo yokutsha. Kwiindawo ezibandayo, injini ifuna umxube otyebileyo ukuze iqale kakuhle. Isivamvo sobushushu bamanzi siya kubuyisela isignali yobushushu obuphantsi kwiyunithi yolawulo, kwaye iyunithi yolawulo iya kunyusa umthamo wokufakwa kwepetroli kwaye inyuse ngokufanelekileyo i-engile yokuqhubela phambili yokutsha ukuqinisekisa ukuba injini iqala kakuhle; xa injini ifikelela kubushushu obuqhelekileyo bokusebenza, iya kukhuthaza iyunithi yolawulo ukuba ilungise umthamo wokufakwa kwepetroli kunye nexesha lokutsha, okuvumela ukutsha okupheleleyo kwamafutha, okungaphuculi kuphela ukonga kwamafutha kodwa kuqinisekisa nokukhupha amandla enjini.
Okokugqibela, inika idatha yegeyiji yobushushu bamanzi, ivumela umnini ukuba ajonge imeko yenjini ngexesha langempela. Isenzi sobushushu bamanzi siya kudlulisela ngokulandelelana isignali yobushushu ejongwe ngexesha langempela kwigeyiji yobushushu bamanzi kwideshibhodi yesithuthi. Ngokujonga ukufundwa kwegeyiji yobushushu bamanzi, umnini angaqonda ngokuzenzekelayo ubushushu obusebenzayo benjini. Xa kukho ukungaqheleki kobushushu bamanzi, umnini angathatha amanyathelo ngokukhawuleza aze amise imoto ukuze ihlolwe ukuze aphephe iimpazamo ezinkulu ezibangelwa kukushisa kakhulu okanye ukupholisa injini.
Iimpazamo eziqhelekileyo kunye nokusombulula iingxaki zeSensor yoBushushu bamanzi enjini
Njengenxalenye ye-elektroniki, isenzi sobushushu bamanzi sinokungasebenzi kakuhle ngenxa yokwaluphala, iimpazamo zesekethe, okanye ungcoliseko ngexesha lokusetyenziswa ixesha elide, nto leyo echaphazela ukusebenza kwesithuthi okuqhelekileyo. Iindlela eziqhelekileyo zokubonakalisa iimpazamo kunye neendlela zokusombulula iingxaki zezi zilandelayo:
Ukungaqheleki kwegeyiji yobushushu bamanzi kwideshibhodi Le yeyona nto ibonakalayo yokusilela kwesenzi sobushushu bamanzi. Xa isekethe yangaphakathi yesenzi sobushushu bamanzi inqanyuliwe, ayinakudlulisela isignali yobushushu kwiyunithi yolawulo, kwaye isalathisi sobushushu bamanzi siya kuhlala sikwi-"0", nokuba injini ifikelela kubushushu obuqhelekileyo, iya kuhlala ingatshintshanga; ngelixa xa isenzi sifutshane, ukumelana kuyehla kakhulu, kwaye iyunithi yolawulo iya kugweba injini ngempazamo njengeshushu kakhulu, isalathisi sobushushu bamanzi siya kufikelela ngqo kwindawo ebomvu ephezulu, kwaye kwangaxeshanye, isibane sesilumkiso sobushushu bamanzi siya kuvulwa. Kule meko, umnini unokuqala ajonge ukuba uqhagamshelo lwentambo yesenzi sobushushu bamanzi lukhululekile okanye lunyibilikisiwe. Ukuba intambo iqhelekile, kusenokwenzeka ukuba isenzi sobushushu bamanzi sonakele, kwaye kufuneka kutshintshwe.
Ubunzima ekuqaliseni injini ebandayo kunye nokungaqhubi kakuhle. Xa uqalisa injini ebandayo, ukuba isenzi sobushushu bamanzi sinengxaki kwaye siphendula isignali yobushushu bokufudumala, iyunithi yokulawula iya kubonelela ngomxube omncinci ngokwemeko yokufudumeza, nto leyo ebangela ukuba injini ibe nobunzima ekuqaliseni ngenxa yomxube omncinci. Ukongeza, isenzi sobushushu bamanzi esinengxaki siya kubangela ukungaqhubi kakuhle, xa injini ebandayo ichaza ubushushu obuphezulu ngendlela engafanelekanga, isantya sokungaqhubi kakuhle siya kwehla kakhulu, kwaye injini iya kunyikima ngokubonakalayo; Ukuba imoto ichaza ubushushu obuphantsi ngexesha lokufudumeza, isantya sokungaqhubi kakuhle siya kunyuka kwaye ingxolo iya kwanda. Xa kwenzeka impazamo enjalo, umnini angasebenzisa i-multimeter ukubona utshintsho lokuxhathisa kwesenzi sobushushu bamanzi. Ngokufudumeza isenzi sobushushu ngesixhobo sombane sokumisa iinwele, ukuba ixabiso lokuxhathisa alitshintshi, oko kubonisa ukuba isenzi sonakele kwaye kufuneka sitshintshwe ngexesha.
Ukonyuka kokusetyenziswa kwepetroli kunye nokwehla kwamandla kubangelwa kukungasebenzi kakuhle kwesensa yobushushu bamanzi. Oku kunokukhokelela ekuphambukeni kulawulo lweyunithi yolawulo lomthamo wokujova ipetroli. Umzekelo, xa isensa ichaza gwenxa isignali yobushushu obuphantsi, iyunithi yolawulo iya kunyusa rhoqo umthamo wokujova ipetroli, nto leyo ebangela inkunkuma yepetroli kunye nokwanda okukhulu kokusetyenziswa kwepetroli; kwangaxeshanye, isignali engalunganga iya kuchaphazela nexesha lokutsha, ibangele ukungoneli kwamandla enjini kunye nokukhawulezisa okubuthathaka. Ukuba umnini uqaphela ukuba ukusetyenziswa kwepetroli kuye kwanda ngequbuliso ngendlela engaqondakaliyo kwaye amandla ehlile kutshanje, emva kokukhupha izinto ezifana noxinzelelo lwamatayara kunye nemikhwa yokuqhuba, kufuneka baqwalasele ukuba kunokwenzeka ukuba isensa yobushushu bamanzi ingasebenzi kwaye bayivavanye ngokukhawuleza kwivenkile yokulungisa yobungcali.
Iplagi yenzwa yobushushu bamanzi yemoto yinxalenye ebalulekileyo yokusebenza kwenjini okuqhelekileyo. Ukusebenza kwayo ngokuchanekileyo kuqinisekisa ukusebenza okuzinzileyo kwenjini phantsi kweemeko ezahlukeneyo zokusebenza. Xa usebenzisa imoto imihla ngemihla, abanini bemoto kufuneka banikele ingqalelo esondeleyo ekufundweni kwegeyiji yobushushu bamanzi, imeko yokuqala, kunye notshintsho ekusetyenzisweni kwepetroli. Ukuba kukho naziphi na iingxaki ezifunyenweyo, kufuneka bajonge ngokukhawuleza ukuba iplagi yenzwa yobushushu bamanzi ayisebenzi kakuhle na. Ukugcinwa rhoqo kobuchwephesha kwesithuthi kunokwandisa ubomi benkonzo yeplagi yenzwa yobushushu bamanzi, ukugcina injini ikwimeko elungileyo yokusebenza kunye nokubonelela ngesiqinisekiso esithembekileyo sokhuseleko lokuqhuba kunye namava okuqhuba.
