Thatha isivamvo soxinzelelo oluninzi.
Ukungenisa i-sensor yoxinzelelo oluninzi lwesakhiwo
Ngenxa yokuba kukho isiphaluka seamplifier ngaphakathi kwinzwa yoxinzelelo oluphindaphindiweyo, idinga iingcingo ezintathu ezipheleleyo zomgca wamandla, umgca ophantsi kunye nomgca wokuphuma kwesignali, ngokuhambelanayo uneetheminali ezintathu kwiitheminali zocingo, ngokulandelelana, i-terminal yamandla (Vcc), i-terminal yomhlaba (E) kunye ne-terminal ye-signal output (PIM), kwaye iitheminali ezintathu ziqhagamshelwe kwikhompyutheni yokulawula i-ECU kunye nentambo yocingo.
Ukuze kuncitshiswe ukungcangcazela kwamacandelo e-elektroniki angaphakathi kwi-sensor ye-intake manifold pressure sensor, idla ngokufakwa kwindawo apho ukungcangcazela kwesithuthi kuncinci, kwaye ngaphezu kwe-intake air main ukuthintela igesi kwi-intake manifold from invacing the sensor pressure. Ukongeza, isivamvo soxinzelelo esithathayo samkela uxinzelelo lombhobho wokuthatha ukusuka ngezantsi ukunqanda indawo yokuvalelwa komqondiso ukuba ingangcoliseki, ngoko ke irhasi yombhobho wokuthatha eqokelelwe kwi-intake manifold kufutshane ne-throttle ngokusebenzisa ityhubhu yerabha ifikeleleke ukusuka kwisiphelo esisezantsi senzwa yoxinzelelo oluninzi.
Ukufunyanwa kwe-Monomer
1. Ukuhlolwa kwembonakalo
Xa ujonga, fumana ngokulula i-hose yerabha ukusuka kwindawo yokuthatha kufutshane nesiphelo se-throttle ukuze ufumane isivamvo soxinzelelo oluphindaphindiweyo kwimoto. Okokuqala, ngesitshixo somlilo esivaliweyo, khangela ukuba i-intake manifold pressure sensor wire connector iqhagamshelwe kakuhle kwaye umbhobho werabha ucimile. Emva koko qala i-injini ukuze ubone ukuba ithumbu lerabha alivalwanga ncam kwaye liyavuza
2. Uvavanyo lwesixhobo
(1) Vula i-ignition switch (ON), kwaye uvavanye ixabiso lombane phakathi kwe-terminal Vcc kunye ne-E2 kunye ne-DC yokumisa i-voltage ye-multimeter (DCV-20). Ixabiso lombane lixabiso lombane lombane elidityaniswe yi-ECU kwi-sensor yoxinzelelo oluninzi. Ixabiso eliqhelekileyo kufuneka libe: Phakathi kwe-4.5 kunye ne-5.5V, ukuba ixabiso alilungile, kufuneka uhlolisise i-voltage yebhetri okanye uxhulumaniso phakathi kweengcingo, ngamanye amaxesha ingxaki ingaba nayo kwi-ECU yekhompyutha yokulawula.
(2) Vula iswitshi yokutshisa (kwindawo), kwaye utsale umbhobho werabha evacuum ukusuka kwisivamvo soxinzelelo se-intake manifold, ukuze ukuthathwa kwesivamvo soxinzelelo lwe-intake manifold iqhagamshelwe kwi-atmosfera, emva koko uvavanye isignali yombane we-terminal output (ixabiso lombane phakathi kwe-PIM kunye nocingo lomhlaba E2), ixabiso eliqhelekileyo li: Phakathi kwe-3.3 ne-3. Ukuthatha isivamvo soxinzelelo oluphindaphindeneyo kunempazamo kwaye kufuneka kutshintshwe.
3 Ixabiso le-voltage kufuneka linyuke ngokuhambelana nokukhula koxinzelelo olubi olusetyenzisiweyo, ngaphandle koko, kubonisa ukuba isiphaluka sokubona umqondiso kwi-sensor iphosakele kwaye kufuneka itshintshwe.
Sibekwe phi isivamvo soxinzelelo oluphindaphindayo?
I-sensor yoxinzelelo lwe-intake manifold intake inzwa efakwe kwi-intake manifold gas pipe, apho iingcingo ezintathu, enye i-5 volts, enye i-5 volts yendlela yokubuya, oko kukuthi, umgca ongalunganga, kunye nomnye umgca wesignali we-Ecu.
I-sensor yoxinzelelo lwe-intake manifold luhlobo olubaluleke kakhulu lwenzwa kuHlobo lwe-D, oko kukuthi, iisistim ze-injection ye-velocity density fuel injection, edlala indima yokuguqula utshintsho loxinzelelo kwi-manifold intake ibe ngumqondiso wombane.
Ikhomputha yokulawula (ECU) inquma inani lomoya ongena kwi-cylinder ngokusekelwe kulo mqondiso kunye nesantya se-injini (uphawu olunikezwa yi-injini yesantya efakwe kwi-distributor).
Isivamvo soxinzelelo lokuthatha sibona uxinzelelo olupheleleyo lwendlela yokungena emva kweqhina kunye nevalve, kwaye ibona utshintsho loxinzelelo olupheleleyo kwi-manifold ngokwesantya senjini kunye nomthwalo.
Emva koko iguqulwa ibe yivoltheji yomqondiso kwaye ithunyelwe kwisilawuli se-elektroniki (ECU), esilawula isixa esisisiseko sokutofa kwamafutha ngokobukhulu balo mbane wophawu.
