Ifanele Volvo iloli fuel umfutho inzwa 21634024

Ukutholwa kwenzwa ye-automobile throttle position with switch output.

(1) Isakhiwo nomjikelezo

Inzwa ye-Throttle position ne-on-off output ibizwa nangokuthi i-throttle switch. Inamapheya amabili othintana naye, okungukuthi i-idle contact (IDL) kanye nomthwalo ogcwele wokuxhumana (PSW). I-cam coaxial ene-throttle valve ilawula ukuvulwa nokuvalwa koxhumana nabo ababili bokushintshwa. Lapho i-throttle valve isendaweni evalekile ngokugcwele, i-IDL yokuxhumana engenzi lutho iyavalwa, futhi i-ECU inqume ukuthi injini isesimweni sokungenzi lutho ngokuhambisana nesignali yokuvala ye-idle switch, ukuze kulawulwe umthamo womjovo kaphethiloli ngokuya izidingo zesimo sokungenzi lutho sokusebenza; Lapho i-valve ye-throttle ivuliwe, othintana naye ongenzi lutho uvuliwe, futhi i-ECU ilawula umjovo kaphethiloli ngaphansi kwesimo soguquko kusukela ngesivinini esingenzi lutho ukuya ekulayisheni ukukhanya ngokusho kwalesi siginali; Othintana naye ogcwele umthwalo uhlala evulekile ebangeni ukusuka endaweni evaliwe ngokuphelele ye-throttle kuya ekuvuleni okuphakathi nendawo nokuncane. Lapho i-throttle ivulwa nge-engeli ethile (i-55 ye-Toyota 1G-EU), othintana naye ogcwele umthwalo uqala ukuvala, ukuthumela isignali yokuthi injini isesimweni sokusebenza komthwalo ogcwele ku-ECU, futhi i-ECU yenza ukunothisa komthwalo ogcwele. lawula ngokwalesi siginali. Inzwa ye-Throttle position ene-switch output yohlelo lokulawula ngogesi lweToyota 1G-EU injini.

(2) Hlola futhi ulungise inzwa yokuma kwe-throttle ngokukhipha okuvuliwe.

① Hlola ukuqhubeka phakathi kwamatheminali ebhasi.

Vula iswishi yokushisa ibe yindawo ethi "VALIWE", khipha isixhumi senzwa ye-throttle position, bese ufaka igeji yogqinsi enogqinsi olufanele phakathi kwesikulufu somkhawulo we-throttle kanye nelever yomkhawulo; Linganisa ukuqhubeka kokuthintana okungenzi lutho nokuxhumana okugcwele komthwalo kusixhumi senzwa ye-throttle position nge-multimeter Ω.

Uma i-throttle valve ivaliwe ngokugcwele, i-IDL yokuxhumana engenzi lutho kufanele ivulwe; Uma i-throttle valve ivuliwe ngokugcwele noma icishe ivuleke ngokugcwele, i-PSW yokuxhumana nomthwalo ogcwele kufanele ivulwe; Kwezinye izikhala, bobabili oxhumana nabo akumele bashayele. Imininingwane iboniswa kuThebula 1. Uma kungenjalo, lungisa noma shintsha inzwa yokuma kwe-throttle.
