Umsebenzi we-automobile camshaft phase control valve
Indima ephambili yevalvu yokulawula i-sensor yesigaba se-camshaft kukulawula ukungena kunye nokufuduswa kwe-injini, ngaloo ndlela kuphucula ukusebenza kwe-injini kunye noqoqosho lwamafutha. Ngokukodwa, i-valve yokulawula ichaphazela ixesha lokuvula kunye nokuvala i-valve ngokutshintsha i-Angle yesigaba se-camshaft, echaphazela ukungeniswa kunye nokukhupha umthamo we-injini. Lo mmiselo unokunceda injini ukuba ifezekise eyona nto isebenzayo yokutsha kunye noqoqosho phantsi kweemeko ezahlukeneyo zokusebenza.
Umgaqo wokusebenza
Izivalo zokulawula i-sensor yesigaba se-Camshaft zihlala zisebenza kunye nabalawuli besigaba se-camshaft. Xa i-sensor ibona imeko yokusebenza ye-injini, isibonakaliso sithunyelwa kwi-ECU (iyunithi yokulawula i-electronic), kwaye i-ECU ilungisa indawo yevalve yokulawula ngokwale miqondiso, ngaloo ndlela iguqula i-Angle yesigaba se-camshaft. Le nkqubo yenziwa nokuba kunge-hydraulically okanye ngombane, enokwahluka ngokuxhomekeke kwimodeli kunye noyilo.
Isiphumo sempazamo
Ukuba i-valve yokulawula i-sensor yesigaba se-camshaft iyasilela, inokukhokelela ekunciphiseni ukusebenza kwe-injini, ukunyuka kokusetyenziswa kwepetroli, kunye nokunyuka kokukhutshwa kwezinto. Ngokomzekelo, ukuba i-valve yokulawula ayilungelelanisi i-Angle yesigaba ngokuchanekileyo, inokubangela ukuba ixesha le-valve lingachanekanga, elichaphazela ukusebenza kakuhle kokutsha, okukhokelela kumandla angaphantsi kunye nokwanda kokusetyenziswa kwe-fuel.
Isiphakamiso sesondlo
Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwe-valve yokulawula i-sensor yesigaba se-camshaft, kucetyiswa ukuba uhlolisise kwaye ugcine iindawo ezifanelekileyo rhoqo. Oku kubandakanya ukujonga umgangatho we-oyile ye-hydraulic system, ukucoca okanye ukubuyisela izihluzo ezivaliweyo, kunye nokujonga rhoqo ukudibanisa kombane. Ukongeza, kuphephe ukuqhuba isithuthi ixesha elide kwindawo enzima ukunciphisa umonakalo kwivalvu yokulawula.
Iimpawu zokungaphumeleli kwevalvu ye-automotive camshaft isigaba solawulo ikakhulu ziquka:
Ubunzima okanye ukungakwazi ukuqalisa : I-ECU ayikwazi ukufumana isignali yendawo yecamshaft, okukhokelela ekudidekeni kwexesha lokutshisa, kwaye injini kunzima ukuyiqalisa.
ijitha ye-injini okanye ukuhla kwamandla : Impazamo yexesha lokulayita ibangele ukutsha okungafanelekanga, i-injini inokuthi i-jitter okomzuzwana, isantya esibuthathaka.
ukonyuka kokusetyenziswa kwepetroli, ukukhutshwa kwezinto ezikhutshwa mandundu : I-ECU inokungena "kwimo yongxamiseko", isebenzisa iiparitha zenaliti ezisisigxina, ezikhokelela kuqoqosho oluphantsi lwepetroli kunye nokukhutshwa kombhobho ogqithisileyo.
Isibane sesiphoso sivuliwe : inkqubo yokuxilonga ekwibhodi (OBD) ibona isignali yenzwa engaqhelekanga kwaye ibangele ikhowudi yempazamo (umz. P0340) .
Ukuzinza okanye ukungazinzi kokungenzi nto : Xa isignali yenzwa iphazamiseka, i-ECU isenokungakwazi ukugcina isantya esiqhelekileyo sokungenzi nto, okukhokelela ekumeni ngequbuliso injini.
Imveliso yamandla elinganiselweyo : Ezinye iimodeli zinciphisa amandla e-injini ukukhusela inkqubo.
Izizathu zokusilela zinokubandakanya:
Isivamvo ngokwaso sonakaliswe : ukuguga kwamalungu e-elektroniki angaphakathi, ukusilela kwamacandelo okwenziwa ngumagnethi, isekethe emfutshane okanye isekethe evulekileyo.
Ukusilela kwesekethe okanye iplagi : iplagi ifakwe ioksijini okanye ikhululekile, iintambo zinxitywe, zifutshane okanye zaphukile (umzekelo bubushushu okanye ngeempuku).
Ukungcola kwenzwa okanye ukungena kwe-oyile : i-sludge okanye i-debris yetsimbi iqhotyoshelwe kumphezulu wenzwa, echaphazela ukuqokelelwa kwesignali.
Ingxaki yokufakela : Ukukhutshwa okungafanelekanga kwenzwa (umzekelo, umgama phakathi kwe-sensor kunye ne-camshaft gear ikude kakhulu), ukukhulula izikrufu zokulungisa.
Olunye ukusilela okuhambelanayo: ibhanti lexesha / ukungahambi kakuhle kwekhonkco, ukusilela kwesivamvo se-crankshaft, ukusilela kwe-ECU, okanye ukuphazamiseka kombane.
Uvavanyo kunye neendlela zokulungisa ziquka:
Funda ikhowudi yempazamo : Sebenzisa isixhobo sokuxilonga se-OBD ukufunda ikhowudi yempazamo (efana ne-P0340) kwaye uqinisekise ukuba ngaba yimpazamo yoluvo lwe-camshaft.
Qwalasela iingcingo zoluvo kunye neplagi yeplagi : khangela ukuba iplagi ikhululekile, idlekile, intambo yokubopha intambo ayonakaliswanga, lungisa okanye uyibuyisele ukuba kuyimfuneko.
Inzwa ecocekileyo : Susa inzwa kwaye ususe i-oyile engaphezulu okanye i-debris kunye ne-carburetor cleaner (ukunyamekela ukuphepha umonakalo womzimba) .
Ukulinganisa ukuxhathisa kwenzwa okanye umqondiso : Sebenzisa i-multimeter ukuvavanya ukuba i-sensor resistant idibana nomgangatho we-manual; Sebenzisa i-oscilloscope ukujonga ukuba i-waveform yomqondiso iqhelekile na.
Buyisela inzwa : ukuba kuqinisekisiwe ukuba inzwa yonakele, buyisela iindawo zoqobo okanye ezithembekileyo ze-brand (nikela ingqalelo kwi-clean kunye ne-torque ngexesha lofakelo).
Qwalasela isixokelelwano sexesha : ukuba impazamo inxulumene nexesha (elifana namazinyo okutsiba ibhanti lexesha), kufuneka uphinde ulufunde kwakhona uphawu lwexesha.
Coca ikhowudi yempazamo kwaye uyiqhube : cima ikhowudi yempazamo emva kokugcinwa, kwaye wenze uvavanyo lwendlela ukuze ubone ukuba impazamo isuswe ngokupheleleyo.
