Umsebenzi wevalvu yokulawula isenzi sesigaba se-camshaft yemoto
Indima ephambili yevalvu yokulawula isenzi se-camshaft phase kukulawula ukungena kunye nokufuduka kwenjini, ngaloo ndlela kuphucula ukusebenza kwenjini kunye noqoqosho lwamafutha . Ngokukodwa, ivalvu yokulawula ichaphazela ixesha lokuvula nokuvala kwevalvu ngokutshintsha i-Angle yesigaba se-camshaft, nto leyo echaphazela umthamo wokungenisa kunye nokukhupha injini. Lo mgaqo unokunceda injini ukuba ifezekise ukusebenza kakuhle komlilo kunye nokonga phantsi kweemeko ezahlukeneyo zokusebenza .
Umgaqo wokusebenza
Iivalvu zokulawula i-sensor phase ye-Camshaft zihlala zisebenza nabalawuli be-camshaft phase. Xa i-sensor ibona imeko yokusebenza kwenjini, isignali idluliselwa kwi-ECU (iyunithi yolawulo lwe-elektroniki), kwaye i-ECU ilungisa indawo yevalvu yokulawula ngokwezi mpawu, ngaloo ndlela itshintsha i-Angle yesigaba se-camshaft. Le nkqubo yenziwa nge-hydraulic okanye ngombane, enokwahluka ngokuxhomekeke kwimodeli kunye noyilo .
Isiphumo sempazamo
Ukuba ivalvu yokulawula i-camshaft phase sensor iyasilela, inokukhokelela ekusebenzeni okuphantsi kwenjini, ukusetyenziswa kwepetroli okwandileyo, kunye nokukhutshwa komoya okubi ngakumbi. Umzekelo, ukuba ivalvu yokulawula ayilungisi i-Angle yesigaba ngokuchanekileyo, inokubangela ukuba ivalvu ingasebenzi kakuhle, ichaphazele ukusebenza kakuhle kokutsha, okubangela ukuba amandla angaphantsi kwamandla kunye nokusetyenziswa kwepetroli okwandileyo.
Ingcebiso yolondolozo
Ukuqinisekisa ukusebenza okuqhelekileyo kwevalvu yokulawula isenzi se-camshaft phase, kuyacetyiswa ukuba ujonge kwaye ugcine iindawo ezifanelekileyo rhoqo. Oku kuquka ukujonga umgangatho weoyile yenkqubo ye-hydraulic, ukucoca okanye ukutshintsha izihluzi ezivalekileyo, kunye nokujonga rhoqo uqhagamshelo lombane. Ukongeza, kuphephe ukuqhuba imoto ixesha elide kwiindawo ezinzima ukunciphisa umonakalo kwivalvu yokulawula .
Iimpawu zokungaphumeleli kwevalvu yokulawula i-sensor yesigaba se-camshaft yemoto ziquka:
Ubunzima okanye ukungakwazi ukuqala: I-ECU ayikwazi ukufumana isignali yendawo ye-camshaft, nto leyo ebangela ukudideka ngexesha lokutsha, kwaye kunzima ukuyiqalisa injini.
ukujitha kwenjini okanye ukuhla kwamandla: impazamo yexesha lokutsha okubangela ukutsha okunganelanga, injini inokujitha ngamaxesha athile, ukukhawulezisa okubuthathaka.
ukusetyenziswa kwepetroli okwandileyo, ukukhutshwa kwepetroli okubi ngakumbi: I-ECU ingangena "kwimo yongxamiseko", isebenzisa iiparameter zokujova ezizinzileyo, nto leyo ekhokelela ekuwohlokeni kokusetyenziswa kwepetroli kunye nokukhutshwa kwepetroli okugqithisileyo.
Isibane sempazamo sivuliwe: inkqubo yokuxilonga ekwibhodi (i-OBD) ibona isignali yenzwa engaqhelekanga kwaye iqalise ikhowudi yempazamo (umz. P0340).
ukungazinzi okanye ukungahlali kakuhle: Xa isignali yesenzwa iphazamisekile, i-ECU isenokungakwazi ukugcina isantya esiqhelekileyo sokungazinzi, nto leyo ebangela ukuba injini ingazinzi ngequbuliso.
Amandla akhutshwayo alinganiselweyo: Ezinye iimodeli zinciphisa amandla enjini ukukhusela inkqubo.
Izizathu zokungaphumeleli zingabandakanya:
Isensor ngokwayo yonakele: ukuguga kwezixhobo ze-elektroniki zangaphakathi, ukungasebenzi kakuhle kwezixhobo ze-magnetic induction, i-short circuit okanye i-open circuit.
Ukusilela kwesekethe okanye iplagi: iplagi iyanyibilika okanye ikhululekile, ihanjisi igugile, ifinyeziwe okanye yaphukile (umz. bubushushu okanye ziimpuku).
Ukungena kokungcola kwesensor okanye ioyile: inkunkuma yodaka okanye yesinyithi inamathele kumphezulu wesensor, nto leyo echaphazela ukuqokelelwa kwesignali.
Ingxaki yokufakela: ukususwa okungafanelekanga kwesensor (umzekelo, umgama phakathi kwesensor kunye negiya ye-camshaft ukude kakhulu), izikrufu zokulungisa ezikhululekileyo.
Ezinye iingxaki ezinxulumene noko: ukungalingani kwebhanti yexesha/itsheyini, ukungaphumeleli kwesenzi sendawo ye-crankshaft, ukungaphumeleli kwe-ECU, okanye ukuphazamiseka kwe-electromagnetic.
Iindlela zokuvavanya nokulungisa ziquka:
Funda ikhowudi yempazamo: Sebenzisa isixhobo sokuxilonga se-OBD ukuze ufunde ikhowudi yempazamo (efana ne-P0340) kwaye uqinisekise ukuba yimpazamo yesenzwa ye-camshaft.
Jonga iingcingo zesensor kunye neplagi: khangela ukuba iplagi ikhululekile, idlakadlaka, intambo yokubopha ayonakali, lungisa okanye utshintshe ukuba kuyimfuneko.
Isensor ecocekileyo: Susa isensor kwaye ususe ioyile yomphezulu okanye inkunkuma ngesicoci sekhaburetha (uqaphele ukunqanda umonakalo emzimbeni).
Linganisa ukumelana kwenzwa okanye isignali: Sebenzisa i-multimeter ukuvavanya ukuba ukumelana kwenzwa kuyahlangabezana na nomgangatho omiselweyo ngesandla; Sebenzisa i-oscilloscope ukujonga ukuba imo ye-signal waveform iqhelekile na.
Tshintsha i-sensor: ukuba kuqinisekisiwe ukuba i-sensor yonakele, tshintsha iindawo zokuqala okanye ezithembekileyo zophawu (qaphela ukuvuleka kunye ne-torque ngexesha lokufakwa).
Jonga inkqubo yexesha: ukuba impazamo inxulumene nexesha (njengokutsiba amazinyo ebhanti yexesha), kufuneka uphinde uhlolisise uphawu lwexesha.
Cima ikhowudi yempazamo uze uyiqhube : sula ikhowudi yempazamo emva kokulungiswa, uze wenze uvavanyo lwendlela ukuze ubone ukuba impazamo isusiwe ngokupheleleyo .
