I-Diesel Injector Fuel Injector 0445120053 Bosch for Man Truck Diesel Engine

Kunezindlela eziningana zokuhlola ukusebenza komjovo. Ake sizibhale ngokulandelana ngenkomba enemininingwane ye-algorithm yezenzo.

1. Ukuhlola ngokulinganisa ukumelana
Ungahlola ama-injection ngaphandle kokuwakhipha usebenzisa i-multimeter. Ukuze uqalise, hlola ukuthi yimaphi ama-injection afakwe emotweni yakho - i-impedance ephezulu noma ephansi (ukumelana nogesi). Le datha izodingeka ukuze kwenziwe ukuxilongwa okunembile. Ukuze uhlole ama-injection ngomhloli ngaphandle kokuwakhipha enjinini yangaphakathi evuthayo, udinga ukunamathela kuhlelo olulandelayo:

2. Ukulinganisa ukumelana kwe-injector winding
(1) khipha izintambo ezinamandla kagesi kuma-injection;
setha i-multimeter kumodi yokulinganisa ukumelana nokufakwa (ohmmeter) ebangeni ukusuka ku-0 kuye ku-200 ohms (kuye ngokuthi imingcele yezobuchwepheshe yedivayisi, umkhawulo ongaphezulu ungahluka, okubaluleke kakhulu, ukuze i-ohmmeter ingakhombisa inani lokumelana amashumi amaningana ama-ohms);
(2) cisha umlilo futhi ukhiphe itheminali enegethivu ebhethrini;
nqamula isixhumi sikagesi ku-injector etholwayo (imvamisa, ngenxa yalokhu, isiqeshana sokukhweza esitholakala kumzimba webhulokhi sinqanyuliwe);
xhuma imikhondo yokuhlola yomhloli kumkhondo womjovo futhi ulinganise.
Ama-impedans ama-injection aphezulu anokumelana nokufakwa ngaphakathi kwe-11…17 Ohm, kanye ne-impedance ephansi — 2…5 Ohm.

Uma inani lokumelana nokufakwa okulinganiselwe lihluka kakhulu kunani elishiwo, lokhu kubonisa ukuthi umjovo unephutha. Ngakho-ke, i-nozzle kufanele ihlakazwe futhi kuhlolwe kabanzi.

Khumbula ukuthi lapho uhlola ama-injection nge-multimeter, udinga ukuxilonga wonke amadivaysi ngamunye ngamunye! Ngakho ungabheka ukuthi yimuphi umjovo ongasebenzi.
Kubalulekile ukwazi ukuthi i-voltage eya kuma-injection avela ku-ECU inikezwa ngefomu le-pulsed, hhayi eliqhubekayo. Ngakho-ke, akunconywa ukukala ukumelana ne-ohmmeter kuphela, kodwa futhi ukuthatha i-oscillogram ye-impulse voltage transfer usebenzisa i-oscilloscope, ukuze ubone ukuthi iyiphi i-voltage ephezulu edingekayo. Umhloli uzokukhombisa amanani amaphakathi kuphela.
