Iphampu Yokujova Isibaseli Esicindezela Kakhulu 131017951 Yenjini 403A 104A-44TG2 1006TAG1A

Kunezinhlobo ezintathu zamasekethe okulawula iphampu kaphethiloli: Isekethe yokulawula iphampu kaphethiloli elawulwa yi-ECU, isekethe yokulawula iphampu kaphethiloli eshintshwayo, kanye nesekethe yokulawula iphampu kaphethiloli enokulawula isivinini.

I-1.ECU elawulwa yi-oil pump control circuit

(1) Uma inkinobho yokushisa ivuliwe, okwamanje igeleza ikhoyili edluliselwe phambili, othintana nabo bavaliwe, futhi amandla okunikezwa kwamandla ku-EFI.

(2) Lapho injini iqalwa, itheminali yokuqala (ST) yeswishi yokuthungela ixhunyiwe, futhi ikhoyili L2 ku-relay ye-circuit breaker inikwa amandla, okwenza ukumunca ukuvala othintana nabo be-relay breaker. Ukunikezwa kwamandla kunikezwa kupompo likaphethiloli, futhi iphampu yamafutha iyasetshenziswa.

(3) Uma injini isiqalile, inzwa yesivinini izofaka isignali yesivinini senjini engu-Ne ku-ECU. Ngalesi sikhathi, i-transistor VT ku-ECU ivuliwe, futhi i-coil L1 ku-relay breaker relay inikezwa amandla, ukuze othintana nabo baqhubeke behlala bevaliwe, futhi iphampu yamafutha iyaqhubeka nokusebenza.

(4) Lapho injini iyeka ukusebenza, i-VT iyanqanyulwa, okuxhunywana naye kwe-circuit breaker relay kuyanqanyulwa, ulayini wokuphakela amandla wepompo likaphethiloli uyaphazamiseka, futhi iphampu yamafutha iyayeka ukusebenza.

2. Isifunda sokulawula iphampu yamafutha eshintshwayo

(1) Vula inkinobho yokushisa, othintana nabo abakhulu abadluliswayo bavaliwe, futhi ukunikezwa kwamandla kunikeza amandla ohlelweni lwe-EFI.

(2) Uma uqala, inkinobho yokuthungela ixhunywe kutheminali ye-ST, ikhoyili ye-relay ye-circuit breaker L2 inikwe amandla, izixhumanisi zokudlulisa i-circuit breaker ziyavalwa, futhi iphampu yamafutha iqala ukusebenza.

(3) Injini iyasebenza, futhi umoya ofakwe enjinini ugeleza ngemitha yokugeleza komoya. Ipuleti lokulinganisa kumitha yokugeleza komoya liyazungeza, livula iswishi yepompo likaphethiloli, futhi ikhoyili L1 yerelay ye-circuit breaker iqala ukunikwa amandla.

3. Isifunda sokulawula iphampu yamafutha ngokulawula isivinini

(1) Lapho injini isebenza ngesivinini esiphansi noma esiphakathi nendawo ukuya komthwalo omncane, i-transistor ku-ECU iyavulwa, futhi ikhoyili yesilawuli sephampu yesibaseli inikwe amandla, okubangela ukuthi ukuthintana B kuvalwe. Ngenxa ye-resistor ebekwe ochungechungeni ngesekethe, iphampu yamafutha isebenza ngesivinini esiphansi.

(2) Uma injini isebenza ngesivinini esikhulu nomthwalo osindayo, i-transistor ku-ECU iyanqanyulwa futhi ukuxhumana no-A kuvaliwe. Iphampu kaphethiloli ixhunywe ngqo kugesi futhi isebenza ngesivinini esikhulu.
