Inzwa yokucindezela okuninginingi yokungenisa.
Isakhiwo senzwa yokucindezela okuningi kwe-Intake
Ngenxa yokuthi kukhona isekethe ye-amplifier ngaphakathi kwe-manifold pressure sensor, idinga izintambo ezintathu zomugqa wamandla, umugqa womhlaba kanye nomugqa wokukhipha isignali, ezinamatheminali amathathu kumatheminali okuxhuma, ngokulandelana, i-power terminal (Vcc), i-ground terminal (E) kanye ne-signal output terminal (PIM), kanti amatheminali amathathu axhunywe kwi-control computer ECU ngesixhumi sentambo kanye nentambo.
Ukuze kuncishiswe ukudlidliza kwezingxenye zangaphakathi ze-elekthronikhi ze-incano manifold pressure sensor, imvamisa ifakwa endaweni lapho ukudlidliza kwemoto kuncane khona, futhi kungaphezu komoya oyinhloko wokungenisa ukuvimbela igesi evela ku-incano manifold ukuthi ingangeni ku-pressure sensor. Ngaphezu kwalokho, i-incano manifold pressure sensor yamukela ingcindezi yepayipi lokungenisa elivela ngezansi ukuvimbela ingxenye yokuzwa isignali ukuthi ingonakaliswa, ngakho-ke igesi yepayipi lokungenisa eliqoqwe ku-incano manifold eduze kwe-throttle ngethubhu yerabha lifinyelelwa livela ekugcineni okuphansi kwe-incano manifold pressure sensor.
Ukutholwa kwe-Monomer
1. Ukuhlolwa kokubukeka
Uma ubuka, mane uthole ipayipi lerabha elivela ku-intake manifold eduze kokuphela kwe-throttle ukuze uthole i-manifold pressure sensor emotweni. Okokuqala, uma i-ignition lock ivaliwe, hlola ukuthi isixhumi sentambo se-intake manifold pressure sensor sixhunywe kahle nokuthi ipayipi lerabha livaliwe. Bese uqala injini ukuze ubone ukuthi ipayipi lerabha alivalwanga kahle futhi alivuzanga yini.
2. Ukuhlolwa kwezinsimbi
(1) VULA iswishi yokushisa (VULA), bese uhlola inani le-voltage phakathi kwe-terminal Vcc kanye ne-E2 nge-DC voltage stop ye-multimeter (DCV-20). Inani le-voltage yinani le-voltage yokunikezwa kwamandla elengezwe yi-ECU ku-sensor yokucindezela okuningi. Inani elijwayelekile kufanele libe: Phakathi kuka-4.5 no-5.5V, uma inani lingalungile, kufanele uhlole i-voltage yebhethri noma ukuxhumana phakathi kwezintambo, ngezinye izikhathi inkinga ingaba naku-ECU yekhompyutha yokulawula.
(2) VULA iswishi yokushisa (Isikhundla SOKUVULA), bese udonsa ipayipi lerabha le-vacuum kusuka ku-input manifold pressure sensor, ukuze intake ye-input manifold pressure sensor ixhunywe emoyeni, bese uhlola isignali ye-terminal output voltage (inani le-voltage phakathi kwe-PIM kanye ne-ground wire E2), inani elijwayelekile lingu: Phakathi kuka-3.3 no-3.9V, uma i-output voltage iphezulu kakhulu noma iphansi kakhulu, ikhombisa ukuthi i-input manifold pressure sensor inephutha futhi kufanele ishintshwe.
(3) VULA iswishi yokushisa (indawo YOKUVULA), susa ipayipi lerabha le-vacuum ku-input manifold pressure sensor, faka ingcindezi ehlukile engemihle (izinga le-vacuum) ekungeneni kwe-manifold pressure sensor ngephampu ye-vacuum ephathwayo, bese uhlola inani le-voltage phakathi kwesignali ye-voltage yokudlulisa i-wiring terminal PIM kanye nentambo yomhlabathi E2 ngenkathi usebenzisa ingcindezi. Inani le-voltage kufanele likhuphuke ngokuhambisana nokukhula kwengcindezi engemihle esetshenzisiwe, ngaphandle kwalokho, kubonisa ukuthi isekethe yokuthola isignali ku-sensor inephutha futhi kufanele ishintshwe.
Itholakala kuphi inzwa yokucindezela ye-input manifold?
Inzwa yokucindezela ye-input manifold iyinzwa efakwe epayipini legesi le-input manifold, lapho izintambo ezintathu, enye ingama-volts ama-5, enye ingama-volts ama-5 omzila wokubuya, okungukuthi, umugqa ongemuhle, kanti enye iwumugqa wesiginali we-Ecu.
Inzwa yokucindezela ye-incase manifold iwuhlobo lwenzwa olubaluleke kakhulu ku-Type D, okungukuthi, izinhlelo zokujova uphethiloli wejubane, ezidlala indima yokuguqula ushintsho lokucindezela ku-incase manifold lube isignali ye-voltage.
Ikhompyutha yokulawula (i-ECU) inquma inani lomoya ongena kwisilinda ngokusekelwe kulesi siginali kanye nesivinini senjini (isiginali enikezwa yinzwa yesivinini senjini efakwe ku-distributor).
Inzwa yokucindezela kokungenisa ithola ukucindezela okuphelele kwe-manifold yokungenisa ngemuva kwefindo nevalvu, futhi ithola ushintsho lokucindezela okuphelele ku-manifold ngokuya ngesivinini senjini kanye nomthwalo.
Bese iguqulwa ibe yi-voltage yesiginali bese ithunyelwa kusilawuli se-elekthronikhi (i-ECU), esilawula inani eliyisisekelo lokujova uphethiloli ngokuya ngobukhulu balo voltage yesiginali.
