Faka inzwa yengcindezi eminingi.
Faka isakhiwo senzwa yokucindezela okuningi
Ngenxa yokuthi kunesekhethi ye-amplifier ngaphakathi kwenzwa yokucindezela okuhlukahlukene, idinga ingqikithi yezintambo ezintathu zolayini wamandla, ulayini ophansi kanye nolayini ophumayo wesiginali, nawo onamatheminali amathathu kumatheminali ezintambo, ngokulandelana, i-power terminal (Vcc), i-ground terminal (E) kanye nesiginali ephumayo (PIM), kanye namatheminali amathathu axhunywe kusixhumi sekhompyutha se-ECU nesixhumi socingo.
Ukuze kuncishiswe ukudlidliza kwezingxenye ze-elekthronikhi zangaphakathi zenzwa yokucindezela okuningana, ngokuvamile ifakwa endaweni lapho ukudlidliza kwemoto kukuncane uma kuqhathaniswa, nangaphezulu kwendawo eyinhloko yomoya ongenisayo ukuze kuvinjelwe igesi ephuma ku-multifold intake ukuthi ihlasele inzwa yokucindezela. Ngaphezu kwalokho, inzwa yengcindezi ehlukahlukene yokwamukela yamukela ingcindezi yepayipi elingenayo elisuka ngezansi ukuze kuvinjwe ingxenye yenzwa yesignali ukuthi ingangcoli, ngakho igesi yepayipi elingenisayo eliqoqwe ku-multifold intake eduze ne-throttle ngeshubhu yerabha ifinyelelwa kusukela ekugcineni okuphansi kwenzwa yokucindezela okuhlukahlukene.
Ukutholwa kwe-Monomer
1. Ukuhlolwa kokubukeka
Uma ubuka, vele uthole ipayipi lerabha elisuka endaweni eningi edonsayo eduze komkhawulo we-throttle ukuze uthole inzwa yokucindezela ehlukahlukene emotweni. Okokuqala, uma ikhiya yokuthungela ivaliwe, hlola ukuthi isixhumi sentambo yenzwa yokucindezela okuningana ixhumeke kahle futhi ipayipi lerabha livaliwe. Bese uqala injini ukuze ubone ukuthi ipayipi lerabha alivalwanga ngokuqinile futhi liyavuza
2. Ukuhlolwa kwezinsimbi
(1) VULA inkinobho yokushisa (VULA), bese uhlola inani likagesi phakathi kwetheminali i-Vcc ne-E2 ngesitobhu sikagesi se-DC se-multimeter (DCV-20). Inani le-voltage yinani lamandla kagesi elingezwe yi-ECU kunzwa yokucindezela okuhlukahlukene. Inani elivamile kufanele libe: Phakathi kuka-4.5 no-5.5V, uma inani lingalungile, kufanele uhlole i-voltage yebhethri noma uxhumano phakathi kwezintambo, ngezinye izikhathi inkinga ingase ibe kukhompyutha yokulawula i-ECU.
+ inzwa yokucindezela okuningana inephutha futhi kufanele ishintshwe.
(3) VULA iswishi yokuthungela (VULA indawo), susa ipayipi lerabha evalekile enzwa yokucindezela ehlukahlukene, faka ingcindezi ehlukile ehlukile (i-vacuum degree) lapho ubamba khona inzwa yokucindezela ehlukahlukene ngepompo yevacuum ephathwa ngesandla, bese uhlola inani likagesi phakathi kwe-PIM yesignali ye-wiring yokudlulisa izintambo kanye nentambo yaphansi engu-E2 ngenkathi usebenzisa ingcindezi. Inani le-voltage kufanele likhuphuke ngokuhambisana nokukhula kokucindezela okungalungile okusetshenzisiwe, ngaphandle kwalokho, kubonisa ukuthi isifunda sokuthola isignali kunzwa sinephutha futhi kufanele sishintshwe.
Itholakala kuphi inzwa yengcindezi eningi?
Inzwa ye-pressure manifold intake inzwa efakwe epayipini legesi lokungenisa, lapho izintambo ezintathu, enye i-volts engu-5, enye i-volts engu-5 yomzila wokubuya, okungukuthi, umugqa ongalungile, kanti enye iwumugqa wesiginali we-Ecu.
Inzwa yokucindezela okuningana iwuhlobo olubaluleke kakhulu lwenzwa ku-Type D, okungukuthi, amasistimu omjovo kaphethiloli we-velocity density, edlala indima yokuguqula ukuguqulwa kwengcindezi ku-multifold intake ibe isignali kagesi.
Ikhompuyutha yokulawula (ECU) inquma inani lomoya ongena kusilinda ngokusekelwe kule signali kanye nesivinini senjini (isiginali enikezwe inzwa yesivinini senjini efakwe kumsabalalisi).
Inzwa yokucindezela oyithathayo ithola ukucindezela okuphelele kwe-manifold edonsayo ngemuva kwefindo nevalvu, futhi ithola ukuguqulwa kokucindezela okuphelele ku-manifold ngokuya ngesivinini nomthwalo wenjini.
Ibe isiguqulelwa kugesi wesignali bese ithunyelwa kusilawuli se-electronic (ECU), esilawula inani eliyisisekelo lomjovo kaphethiloli ngokuya ngosayizi wale voltage yesignali.
