Isitofu se-Diesel Injector ye-Fuel 0445120053 Bosch for Man Truck Diesel Injector

Kukho iindlela ezininzi zendlela yokukhangela ukusebenza kwe-injector. Masizidwelise ngokulandelelana kunye nenkcazo ecacileyo ye-algorithm yezenzo.

1. Ukuhlola ngokulinganisa ukuxhathisa
Unokujonga ii-injection ngaphandle kokususa usebenzisa i-multimeter. Ukuze uqalise, khangela ukuba zeziphi ii-injection ezifakwe kwimoto yakho - i-impedance ephezulu okanye ephantsi (ukuxhathisa umbane). Le datha iya kufuneka ukwenza ukuxilongwa ngokuchanekileyo. Ukuze ukhangele ii-injection kunye nomhloli ngaphandle kokuwasusa kwi-injini yokutsha yangaphakathi, kufuneka unamathele kwisicwangciso esilandelayo:

2. Ukulinganisa ukuchasana kwe-injector winding
(1) ukususa iingcingo ezinombane ophezulu kwii-injector;
seta i-multimeter kwindlela yokulinganisa ukuchasana kwe-insulation (ohmmeter) kuluhlu ukusuka kwi-0 ukuya ku-200 ohms (kuxhomekeke kwiiparamitha zobugcisa besixhobo, umda ophezulu unokwahluka, okona kubaluleke kakhulu, ukwenzela ukuba i-ohmmeter ingabonisa ixabiso lokumelana amashumi amaninzi ohm);
(2) cima into yokucima umlilo kwaye ususe i-terminal ekhatywayo ebhetrini;
qhawula umdibaniso wombane kwi-injector efunyaniswayo (ngokuqhelekileyo, kule nto, ikliphu yokunyuka efumaneka kumzimba webhlokhi ikhutshwe);
qhagamshela iintambo zovavanyo lomvavanyi kwi-injector lead kunye nokulinganisa.
Izitofu eziphezulu ze-impedance zine-insulation resistance ngaphakathi kwe-11 ... 17 Ohm, kunye ne-impedance ephantsi - 2 ... 5 Ohm.

Ukuba ixabiso le-insulation resistance resistance lihluke kakhulu kwixabiso elichaziweyo, oku kubonisa ukuba i-injector iphosakele. Ngokufanelekileyo, umlomo kufuneka uqhaqhe kwaye uxilongo olucacileyo kufuneka lwenziwe.

Khumbula ukuba xa ujonga ii-injection nge-multimeter, kufuneka uhlolisise zonke izixhobo nganye nganye! Ngoko unokujonga ukuba yeyiphi na isitofu esingasebenziyo.
Kubalulekile ukwazi ukuba i-voltage kwii-injection ezivela kwi-ECU inikezelwa kwifom ye-pulsed, kungekhona rhoqo. Ngoko ke, akukhuthazwa kuphela ukulinganisa ukuchasana ne-ohmmeter, kodwa kunye nokuthatha i-oscillogram yokudluliselwa kombane we-impulse usebenzisa i-oscilloscope, ngoko unokubona ukuba yiyiphi i-voltage ephezulu ethathayo. Umvavanyi uya kukubonisa kuphela amaxabiso aphakathi.
