Inzwa yoxinzelelo lwe-Intake manifold.
Ulwakhiwo lwesenzi soxinzelelo lwe-Intake manifold
Ngenxa yokuba kukho isekethe ye-amplifier ngaphakathi kwe-manifold pressure sensor, ifuna iingcingo ezintathu zizonke zomgca wombane, umgca womhlaba kunye nomgca wokuphuma kwesignali, ezihambelanayo zineziphelo ezintathu kwiiphelo zocingo, ngokulandelelana, i-power terminal (Vcc), i-ground terminal (E) kunye ne-signal output terminal (PIM), kwaye ezi terminals zintathu ziqhagamshelwe kwi-control computer ECU nge-wire connector kunye ne-wire.
Ukuze kuncitshiswe ukungcangcazela kwezinto ze-elektroniki zangaphakathi ze-incano manifold pressure sensor, idla ngokufakwa kwindawo apho ukungcangcazela kwesithuthi kuncinci, kwaye ngaphezulu komoya ophambili wokungenisa ukuthintela igesi evela kwi-incano manifold ukuba ingangeni kwi-pressure sensor. Ukongeza, i-incano manifold pressure sensor yamkela uxinzelelo lombhobho wokungenisa umbane oluvela ngaphantsi ukuthintela inxalenye yokuva isignali ukuba ingonakaliswa, ngoko ke igesi yombhobho wokungenisa umbane eqokelelwe kwi-incano manifold kufutshane ne-throttle ngetyhubhu yerabha ifikelelwa ukusuka kwisiphelo esisezantsi se-incano manifold pressure sensor.
Ukufunyanwa kweMonomer
1. Ukuhlolwa kwenkangeleko
Xa ujonge, fumana nje ipayipi yerabha kwi-intake manifold kufutshane nesiphelo se-throttle ukuze ufumane i-manifold pressure sensor emotweni. Okokuqala, xa isitshixo sokukhanyisa sivaliwe, jonga ukuba isixhumi sentambo ye-intake manifold pressure sensor siqhagamshelwe kakuhle kwaye ipayipi yerabha icinyiwe. Emva koko qalisa injini ukuze ubone ukuba ipayipi yerabha ayivalwanga kakuhle kwaye ayivuzi.
2. Uvavanyo lwezixhobo
(1) Vula iswitshi yokutsha (VULIWE), kwaye uvavanye ixabiso le-voltage phakathi kwe-terminal Vcc kunye ne-E2 nge-DC voltage stop ye-multimeter (DCV-20). Ixabiso le-voltage lixabiso le-voltage yombane elongezwe yi-ECU kwi-manifold pressure sensor. Ixabiso eliqhelekileyo kufuneka libe: Phakathi kwe-4.5 kunye ne-5.5V, ukuba ixabiso alichanekanga, kufuneka ujonge i-voltage yebhetri okanye unxibelelwano phakathi kweentambo, ngamanye amaxesha ingxaki isenokuba kwi-ECU yekhompyutha yokulawula.
(2) Vula iswitshi yokutsha (isikhundla sokuVULA), uze utsale ipayipi yerabha ye-vacuum kwi-input manifold pressure sensor, ukuze i-intake ye-input manifold pressure sensor iqhagamshelwe emoyeni, uze uvavanye isignali ye-terminal output voltage (ixabiso le-voltage phakathi kwe-PIM kunye ne-ground wire E2), ixabiso eliqhelekileyo li: Phakathi kwe-3.3 kunye ne-3.9V, ukuba i-output voltage iphezulu kakhulu okanye iphantsi kakhulu, ibonisa ukuba i-input manifold pressure sensor inempazamo kwaye kufuneka itshintshwe.
(3) Vula iswitshi yokutsha (indawo yokuVULA), susa ipayipi yerabha ye-vacuum kwi-intake manifold pressure sensor, faka uxinzelelo olubi olwahlukileyo (i-vacuum degree) kwi-intake ye-manifold pressure sensor ngepompo ye-vacuum ephathwayo, kwaye uvavanye ixabiso le-voltage phakathi kwesignali ye-voltage transmission terminal ye-wiring PIM kunye ne-ground wire E2 ngelixa usebenzisa uxinzelelo. Ixabiso le-voltage kufuneka linyuke ngokuthe ngqo ngokukhula koxinzelelo olubi olusetyenzisiweyo, kungenjalo, kubonisa ukuba isekethe yokubona isignali kwi-sensor inempazamo kwaye kufuneka itshintshwe.
Iphi i-input manifold pressure sensor?
I-input manifold pressure sensor yi-sensor efakwe kumbhobho wegesi we-input manifold, apho iingcingo ezintathu, enye ye-volts ezi-5, enye ye-volts ezi-5 zendlela yokubuya, oko kukuthi, umgca ongalunganga, kwaye enye yi-signal line ye-Ecu.
I-input manifold pressure sensor luhlobo olubaluleke kakhulu lwe-sensor kuhlobo D, oko kukuthi, iinkqubo ze-velocity density fuel injection, ezidlala indima yokuguqula utshintsho loxinzelelo kwi-input manifold lube yisignali ye-voltage.
Ikhompyutha yokulawula (i-ECU) imisela ubungakanani bomoya ongena kwisilinda ngokusekelwe kolu phawu kunye nesantya senjini (uphawu olunikezelwa sisiva sesantya senjini esifakwe kumsasazi).
I-input pressure sensor ibona uxinzelelo olupheleleyo lwe-input manifold ngasemva kwe-knot kunye ne-valve, kwaye ibona utshintsho loxinzelelo olupheleleyo kwi-manifold ngokwesantya senjini kunye nomthwalo.
Emva koko iguqulwa ibe yi-voltage yesignali ize ithunyelwe kwi-electronic controller (ECU), elawula ubungakanani be-fuel injection esisiseko ngokobukhulu bale voltage yesignali.
