Enjene ea Mafura ea Diesel Injector 0445120053 Bosch for Man Truck Diesel Engine

Ho na le mekhoa e 'maloa ea ho hlahloba ts'ebetso ea ente. A re li thathamise ka tatellano ka pontšo e qaqileng ea algorithm ea liketso.

1. Ho hlahloba ka ho lekanya khanyetso
U ka hlahloba li-injection ntle le ho li tlosa u sebelisa multimeter. Ho qala, hlahloba hore na ke li-injection life tse kentsoeng koloing ea hau - e phahameng kapa e tlase impedance (ho hanyetsa motlakase). Lintlha tsena li tla hlokahala ho etsa tlhahlobo e nepahetseng. E le hore u hlahlobe li-injection ka tester ntle le ho li tlosa ho enjene ea motlakase e ka hare, u lokela ho khomarela moralo o latelang:

2. Ho lekanya khanyetso ea moea oa ente
(1) tlosa lithapo tse nang le motlakase o mongata ho liente;
seta multimeter ho mokhoa oa ho lekanya ho hanyetsa (ohmmeter) ho tloha ho 0 ho ea ho 200 ohms (ho itšetlehile ka lisebelisoa tsa theknoloji ea sesebelisoa, moeli o ka holimo o ka fapana, haholo-holo, e le hore ohmmeter e ka bontša boleng ba ho hanyetsa. mashome a 'maloa a ohm);
(2) tima lebone mme o tlose terminal e mpe ho betri;
khaola sehokelo sa motlakase ho ente e fumanoeng (hangata, bakeng sa sena, sekotwana se ntseng se hola se lutseng 'meleng oa block se tlosoa);
hokela liteko tsa liteko tsa tester ho li-injector lead le ho lekanya.
Li-injection tse phahameng tsa impedance li na le khanyetso ea insulation ka hare ho 11 ... 17 Ohm, le impedance e tlaase - 2 ... 5 Ohm.

Haeba boleng ba khanyetso bo lekantsoeng bo fapaneng bo fapane haholo le boleng bo boletsoeng, sena se bontša hore ente e fosahetse. Ka hona, molomo o tlameha ho qhaqha 'me ho lokela ho etsoa tlhahlobo e feletseng.

Hopola hore ha u hlahloba liente ka multimeter, u lokela ho hlahloba lisebelisoa tsohle ka bonngoe! Kahoo o ka hlahloba hore na ente e sa sebetseng ke efe.
Ke habohlokoa ho tseba hore motlakase ho li-injection tse tsoang ho ECU o fanoa ka mokhoa oa pulsed, eseng kamehla. Ka hona, ho kgothaletswa eseng feela ho lekanya khanyetso ka ohmmeter, empa hape le ho nka oscillogram ea phetisetso ea motlakase ea impulse ho sebelisa oscilloscope, e le hore u ka bona hore na ho hlokahala eng. Mohlahlobi o tla u bontša feela litekanyetso tse tloaelehileng.
