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, indawo yokugcina amandla (Vcc. ), itheminali yaphansi (E) kanye netheminali yokukhipha isignali (PIM), kanye namatheminali amathathu axhunywe kukhompyutha yokulawula i-ECU ngesixhumi sezintambo nocingo.
Ukuze kuncishiswe ukudlidliza kwezingxenye ze-elekthronikhi zangaphakathi zenzwa yokucindezela okuningana edonsayo, ivamise ukufakwa endaweni lapho ukudlidliza kwemoto kukuncane uma kuqhathaniswa, nangaphezulu kwephayiphu yomoya yokungenisa umoya ukuze kuvinjelwe igesi evela kubuningi bokungena ekuhlaseleni. inzwa yokucindezela. Ukwengeza, inzwa yengcindezi ehlukahlukene yokwamukela yamukela ingcindezi yepayipi elingenayo elisuka ngezansi ukuze kuvinjwe ingxenye yenzwa yesiginali ukuthi ingangcoli, ngakho-ke igesi yepayipi lokungenisa eliqoqwe ku-multifold intake eduze kwe-throttle ngeshubhu lerabha lifinyelelwa kusukela ekugcineni okuphansi kwe- inzwa yengcindezi eminingi.
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.
(2) VULA iswishi yokuthungela (isikhundla), bese udonsa ipayipi lerabha yevacuum kusuka kunzwa yokucindezela ehlukahlukene, ukuze ukuthathwa kwenzwa yokucindezela okuningana edonsayo kuxhumeke emkhathini, bese uvivinya isignali ye-voltage ephumayo yokugcina ( inani le-voltage phakathi kwe-PIM nentambo yaphansi engu-E2), inani elivamile lithi: Phakathi kuka-3.3 no-3.9V, uma i-voltage ephumayo iphezulu kakhulu noma iphansi kakhulu, kubonisa ukuthi inzwa yokucindezela okuningana yokungenisa inephutha futhi kufanele ishintshwe.
(3) VULA iswishi yokuthungela (VULA indawo), khipha ipayipi lerabha evacuum kunzwa yokucindezela ehlukahlukene, faka ingcindezi ehlukile engalungile (i-vacuum degree) ekungeneni kwenzwa yokucindezela okuhlukahlukene ngepompo yokuvala ephathwayo, bese uvivinya inani le-voltage phakathi kwesignali ye-voltage yokudlulisa izintambo ze-PIM kanye nentambo yaphansi engu-E2 ngenkathi ifaka ukucindezela. 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-5 volts, enye i-5 volts yomzila wokubuya, okungukuthi, umugqa ongalungile, kanti enye isignali. umugqa 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.
