ʻO ka hoʻoheheʻe ʻia ʻana o ka pahu pahu pahu 0445120053 Bosch no ke kanaka Truck Diesel Engine

Nui nā ala e nānā ai i ka hana o ka injector. E papa inoa iā lākou me kahi kikoʻī kikoʻī o ka algorithm o nā hana.

1. Ke nānā ʻana ma ke ana ʻana i ke kūʻē
Hiki iā ʻoe ke nānā i nā injectors me ka ʻole e wehe iā lākou me ka hoʻohana ʻana i kahi multimeter. No ka hoʻomaka ʻana, e nānā i nā injectors i hoʻokomo ʻia ma kāu kaʻa - kiʻekiʻe a haʻahaʻa paha impedance (electrical resistance). Pono kēia ʻikepili no ka hana ʻana i kahi hōʻailona pololei. I mea e nānā ai i nā injectors me kahi mea hoʻāʻo me ka ʻole e wehe iā lākou mai ka mīkini hoʻoheheʻe kūloko, pono ʻoe e pili i kēia hoʻolālā:

2. Ana i ke kū'ē o ka injector wili
(1) wehe i nā uwea kiʻekiʻe-voltage mai nā injectors;
E hoʻonoho i ka multimeter i ke ʻano o ke ana ʻana i ke kūpaʻa insulation (ohmmeter) ma ka laulā mai 0 a 200 ohms (ma muli o nā ʻāpana ʻenehana o ka hāmeʻa, ʻokoʻa paha ka palena o luna, ʻo ka mea nui loa, i hiki ai i ka ohmmeter ke hōʻike i kahi waiwai kūʻē o he mau umi ohm);
(2) e hoʻopau i ka pahu ahi a wehe i ka pahu ʻino mai ka pākaukau;
e hoʻokaʻawale i ka mea hoʻopili uila ma ka injector e ʻike ʻia ana (ʻo ka mea maʻamau, no kēia, ʻoki ʻia ke kiʻi e kau ana ma ke kino poloka);
hoʻohui i nā alakaʻi hoʻāʻo o ka mea hōʻike i nā alakaʻi injector a ana.
Loaʻa i nā injectors impedance kiʻekiʻe ke kūpaʻa insulation i loko o 11…17 Ohm, a me ka impedance haʻahaʻa - 2…5 Ohm.

Inā ʻokoʻa loa ka waiwai o ke kūpaʻa insulation i ana ʻia mai ka waiwai i ʻōlelo ʻia, hōʻike kēia i ka hewa o ka injector. No laila, pono e wehe ʻia ka nozzle a pono e hana i kahi hōʻailona kikoʻī.

E hoʻomanaʻo i ka nānā ʻana i nā injectors me kahi multimeter, pono ʻoe e ʻike i nā mea āpau i kēlā me kēia! No laila hiki iā ʻoe ke nānā i ka injector ʻaʻole e hana.
He mea nui e ʻike i ka hāʻawi ʻia ʻana o ka volta i nā injectors mai ka ECU ma kahi ʻano pulsed, ʻaʻole ia he mea mau. No laila, ʻōlelo ʻia ʻaʻole e ana wale i ke kū'ē me ka ohmmeter, akā e lawe pū i kahi oscillogram o ka hoʻoili uila impulse e hoʻohana ana i kahi oscilloscope, no laila hiki iā ʻoe ke ʻike i ke ʻano o ka volta kiʻekiʻe. E hōʻike ka mea hōʻike iā ʻoe i nā waiwai maʻamau.
