ʻO ka mea hoʻoheheʻe Diesel injector wahie 095000-5361 Denso injector no Isuzu

ʻO ka ʻelima ka ʻike mana injector wahie. Wehe i ka pahu uea o ka mea hoʻoheheʻe wahie, e hoʻā i ka laka hoʻāla, hoʻololi i ka multimeter i ka pae voli DC, e ana i ka voluma ma ke kaula uea, e hoʻopili i ke plug me ke alakaʻi hōʻike ʻulaʻula o ka multimeter e hoʻopā i nā pine ʻelua o ka e hoʻopili i kēlā me kēia, a e hoʻopili i ke alakaʻi hoʻāʻo ʻeleʻele ʻē aʻe i ka pūpū engine , a ʻo nā voltages he 12V (ka uila uila i kēlā manawa) a me OV. Inā he OV lākou a pau, e hōʻike ana he pilikia me ka mana o ka wahie injector, a pono e nānā ʻia ka pahu fuse kūpono a me nā mea uila.
ʻO ke ono ka nānā ʻana i ke kaapuni hoʻomalu injector. Wehe i ka wahie injector uea plug, e ho'ā i ka ignition laka, ke 'ulaʻula ho'āʻo alakaʻi o ka multimeter ua pili i na pine elua o ka plug pakahi, aʻeleʻele 'ē aʻe ke alakaʻi i pili i ka engine hihia, nā voltages he 12V a me 0V. pakahi, e imi i ka 0V pine a Mark ia, o keia ka injector mana kaapuni. E hoʻohui i ka pahu uea o ka wahie injector, e hoʻā i ka ignition laka, a ana i ka uila ma waena o ka wahie injector mana laina a me ka engine hihia, e pono e oi aku mamua o 10.5V. ʻO kekahi ʻano hana ʻē aʻe, ʻo ia ka hoʻāʻo ʻana me ka peni hoʻāʻo uila kaʻa, nona nā diodes ʻelua kukui, e wehe i ka plug injector uea wahie, e hoʻohui i nā pine ʻelua o ka peni hoʻāʻo kaʻa i nā pine plug, a hoʻohana i ka mea hoʻomaka e huki E hoʻomaka i ka ʻenekini. , E nānā i nā diodes, pono e ho'omālamalama nā LED i kahi'ē a'e, e hō'ike ana he mea ma'amau ka hō'ailona mana.
ʻO ka ʻehiku ʻo ka ʻike ʻana i ka hōʻailona wahie. E nānā i ka laula o ka pulupulu hoʻoheheʻe wahie me ke kōkua ʻana o kahi mea hana hōʻoia hewa a i ʻole kahi oscilloscope. Ma lalo o nā kūlana maʻamau, ʻo 2 ~ 10mS ka laula o ka pulse injection o ka mīkini. ʻO ka maʻamau, ua māhele ʻia ka ʻike ʻana i ʻehā mau pae, ʻo kekahi ka pae idling; ʻo ka ʻē aʻe ka pae haʻahaʻa liʻiliʻi a waena; ʻo ke kolu ka pae haʻahaʻa kaumaha. ʻO kēia mau ʻanuʻu ʻekolu e nānā i ka kūlike o kēlā me kēia hōʻailona hoʻoheheʻe wahie cylinder. ʻO ka hā o ka ʻoki wahie o ka hahau. Ke pani koke ka enekini i ka throttle i ka mama kiʻekiʻe, pono e hoʻopau ka injector wahie no ka manawa pōkole, a ʻo 0mS ka laulā o ka wahie i loko o kahi manawa pōkole.
