Inzwa yokuhamba komoya - enye yeenzwa ezibalulekileyo ze-injini ye-EFI.
Ukulawulwa kwe-elektroniki kwe-injini yepetroli yokutofa ukuze ufumane eyona ngxubevange yomxube phantsi kweemeko ezahlukeneyo zokusebenza, kuyafuneka ukulinganisa ngokuchanekileyo ubungakanani bomoya obufakwe enjini ngalo lonke ixesha, eyona siseko siphambili sokubala kwe-ECU (ulawulo) lwamafutha. isitofu. Ukuba i-sensor yokuhamba komoya okanye umgca uyasilela, i-ECU ayikwazi ukufumana umqondiso ochanekileyo wegesi, ayikwazi ukulawula inani lenaliti ngokuqhelekileyo, eya kubangela ukuba umxube ube mkhulu kakhulu okanye uncinci kakhulu, ukuze injini ingasebenzi ngokuqhelekileyo. . Kukho iintlobo ezininzi ze-air flow sensors zokulawula i-electronic system injection ye-petroli, kwaye i-sensors ye-airflow eqhelekileyo inokwahlulwa ibe yi-blade (iphiko) uhlobo, uhlobo oluphambili, uhlobo locingo olushushu, uhlobo lwefilimu eshushu, uhlobo lwe-Karman vortex njalo njalo.
Iintlobo ze-5 zeempazamo zenzwa yokuhamba komoya
Isivamvo sokuhamba komoya sisixhobo esiphambili kwinkqubo yolawulo lweenjini zemoto, ukungaphumeleli kwayo kuya kukhokelela ekuthotyweni kokusebenza kwe-injini, ukonyuka kokusetyenziswa kwamafutha, kunye nokuchaphazela ukhuseleko lwesithuthi. Iimpazamo ezintlanu eziqhelekileyo zezivamvo zokuhamba komoya kunye nokubonakaliswa kwazo zezi zilandelayo:
Ukuhamba komoya okungaqhelekanga kunye namandla ombane: oku kunokukhokelela kwisantya esingazinzanga sokungenzi nto, isantya esibuthathaka, ukwanda kokusetyenziswa kwamafutha kunye nezinye iingxaki.
Umbane opheleleyo wokuhamba komoya uphezulu kakhulu okanye uphantsi kakhulu : Oku kubonisa ukuba inzwa ayinakulinganisa ukuhamba ngokuchanekileyo, okunokuchaphazela ukusebenza kwe-injini.
Umxube werhasi obhityileyo kakhulu okanye ongqindilili kakhulu : Oku kunokukhokelela ekubeni injini ingasebenzi kakuhle, isantya esisezantsi isantya, ukusetyenziswa kwepetroli okwandisiweyo kunye nombhobho ongaqhelekanga.
Uphawu olungachanekanga, ukuphazamiseka komqondiso okanye ukungazinzi komqondiso : Ezi ngxaki zinokukhokelela kwinaliti yamafutha eninzi kakhulu okanye encinci kakhulu, echaphazela ukusebenza kwe-injini okuqhelekileyo.
Ukuba into yokucoca umoya ayitshintshwanga ixesha elide okanye ukusetyenziswa kwento ephantsi yokucoca, iya kukhokelela ekuqokeleleni uthuli ngaphakathi kwenzwa yokuhamba komoya, echaphazela ukuchaneka kwayo kunye nobomi benkonzo.
Ukuxilonga nokusombulula ezi mpazamo, ezi ndlela zilandelayo zinokuthathwa:
Ukulinganisa idatha yombane ophumayo we-injini esebenzayo: kwimeko yokungenzi nto ye-injini, umbane wesignali oguquguqukayo wesiphelo somqondiso weplagi kufuneka ube phakathi kwe-0.8 kunye ne-4V; Xa ukukhawuleza kumthwalo opheleleyo, umqondiso we-voltage kufuneka usondele kwi-4V.
Sebenzisa i-multimeter ukuvavanya i-voltage ephumayo ye-sensor : ixabiso eliqhelekileyo lombane kufuneka libe yi-5V, unokuvavanya impendulo ngokuvuthela umoya kwi-sensor.
Khupha iplagi yamandla yenzwa yokuqukuqela komoya xa injini isebenza : gweba ukuba isivamvo sisebenza ngokuqhelekileyo ngokujonga utshintsho lwenjini.
Sebenzisa isixhobo sokufumanisa impazamo ukufunda ikhowudi yempazamo: kwaye uphathe isiphene ngokwekhowudi yempazamo ebonisiweyo.
Ukuba i-sensor ye-air flow ifunyanwe iphosakele, kufuneka ilungiswe okanye itshintshwe ngexesha ukuphepha impembelelo enkulu ekusebenzeni kweenjini.
Indlela yokulungisa inzwa yomoya
Iindlela zokulungisa izinzwa zokuhamba komoya ziquka ukuhlolwa kunye nokucoca, ukutshintshwa kwenzwa, ukulungiswa kweendawo ezonakalisiweyo kunye nokuhlolwa okupheleleyo. ...
Jonga kwaye ucoce inzwa yokuqukuqela komoya : jonga rhoqo ukuba intambo yoqhagamshelo yenzwa yokuhamba komoya ikhululekile okanye yonakele. Ukuba kukho nayiphi na ingxaki efunyenweyo, yilungise okanye uyibuyisele kwangethuba. Ngexesha elifanayo, ukucoca inzwa yokuhamba komoya kunokuphucula ngokufanelekileyo ukuchaneka kwayo. Sebenzisa isixhobo esikhethekileyo sokususa inzwa, uyicoce ngesicoci esinamandla okucoca, sisule sicoceke emva kokucoca kwaye emva koko uyifake.
Tshintsha isivamvo sokuhamba komoya : Ukuba isivamvo sokuhamba komoya ngokwaso asiphumeleli, kufuneka kutshintshwe inzwa entsha. Oku kuhlala kubandakanya ukususa inzwa yoqobo kunye nokufaka entsha.
Lungisa iindawo ezonakeleyo : Ukuba ucingo olushushu okanye olushushu lufile lwenzwa yokuqukuqela komoya lutshisiwe, lwaqhekeka, okanye lumdaka, kufuneka ubuyisele indawo enempazamo. Oku kunokubandakanya ukutshintsha iingcingo ezishushu, ukubumba okushushu, okanye ukucoca umphezulu woluvo ukususa ukwakhiwa kothuli kunye nokungcola.
Ukuhlolwa okupheleleyo : Ukuba kukho ingxaki ngemitha yokuhamba komoya, kungcono ukuba uhlolwe ngokupheleleyo, njengoko ingxaki inokubandakanya imiba yenkqubo enzima ngakumbi. Ukuba kukho ingxaki ngemitha yokuhamba komoya, ukulungiswa akunakuthembeka njengokutshintsha indawo entsha ehambelana nayo.
Ngamafutshane, isivamvo sokuhamba komoya sibalulekile ekusebenzeni okuqhelekileyo kwe-injini, kwaye kufuneka kujongwane nayo ngexesha xa kukho ukusilela ekuqinisekiseni ukuba ukusebenza kwe-injini kunye nokukhutshwayo kuyahlangabezana nemigangatho.
