Thatha isivamvo soxinzelelo oluninzi.
Ukungenisa i-sensor yoxinzelelo oluninzi lwesakhiwo
Ngenxa yokuba kukho isiphaluka seamplifier ngaphakathi kweseva yoxinzelelo oluphindaphindiweyo, idinga iingcingo ezintathu ezipheleleyo zomgca wamandla, umgca osezantsi kunye nomgca wokuphuma komqondiso, ngokuhambelanayo uneetheminali ezintathu kwiitheminali zocingo, ngokulandelelana, i-terminal yamandla (Vcc. ), i-terminal yomhlaba (E) kunye ne-terminal output terminal (PIM), kunye ne-terminals ezintathu zixhunywe kwi-ECU yekhompyutheni yokulawula nge-wire connector kunye nocingo.
Ukuze kuncitshiswe ukungcangcazela kwamacandelo e-elektroniki angaphakathi kwi-sensor yoxinzelelo lwe-intake manifold manifold, idla ngokufakwa kwindawo apho ukungcangcazela kwesithuthi kuncinci, kwaye ngaphezulu kwesixhobo somoya esithathayo ukuthintela irhasi kwi-intake manifold ukuba ingangeni. inzwa yoxinzelelo. Ukongeza, isivamvo soxinzelelo esithathayo siyalwamkela uxinzelelo lombhobho wokuthatha ukusuka ngezantsi ukunqanda indawo yemvakalelo yomqondiso ukuba ingangcoliseki, ngoko ke irhasi yombhobho wokuthatha eqokelelwe kwi-intake manifold kufutshane ne-throttle ngokusebenzisa ityhubhu yerabha ifikeleleka ukusuka ekupheleni kwerabha. isivamvo soxinzelelo 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 ixabiso le-voltage phakathi kwe-PIM kunye ne-ground wire E2), ixabiso eliqhelekileyo: Phakathi kwe-3.3 kunye ne-3.9V, ukuba i-voltage ye-output iphezulu kakhulu okanye iphantsi kakhulu, ibonisa ukuba i-sensor ye-intake manifold pressure sensor iphosakele kwaye kufuneka itshintshwe.
(3) Vula iswitshi yokutshisa (kwindawo), susa umbhobho werabha evacuum kwisivamvo sevacuum yoxinzelelo, sebenzisa uxinzelelo olubi olwahlukileyo (iqondo levacuum) ekuthatheni isivamvo soxinzelelo oluninzi ngempompo yofutha ephathwayo, kwaye uvavanye ixabiso le-voltage phakathi kwe-wiring terminal transmission signal signal ye-PIM kunye nocingo oluphantsi lwe-E2 ngelixa usebenzisa uxinzelelo. 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?
Isivamvo soxinzelelo esithathayo sisiva esifakwe kumbhobho werhasi omninzi, apho iingcingo ezintathu, enye yeye-volts ezi-5, enye yeye-5 volts yendlela yokubuya, oko kukuthi, umgca ongalunganga, kwaye enye iluphawu. umgca 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.
