ʻO ke ʻano a me ke kumu o ka injector

ʻO ka injector wahie he mea kikoʻī me ka pololei machining kiʻekiʻe loa, e koi ana i kahi kahe kahe nui, ikaika anti-clogging a me nā mea hoʻohaumia, a me ka hana atomization maikaʻi. ʻO ke kumu hana o ka wahie injector ʻo ia ka loaʻa ʻana o ka hōʻailona pulse injection i hoʻouna ʻia e ka ECU e hoʻokele pololei i ka nui o ka wahie injection.
ʻO ka injector, ʻo ia ka valve solenoid, e hoʻomalu ʻia e ka ʻenekini mana. ʻO ka'enela ma lalo o ke kaomi o ka paipu hoʻolaha aila e komo i ka injector wahie, ma lalo o ka ikaika o ka pūnāwai hoʻihoʻi, ua paʻa ka valve needle, aʻaʻole hiki ke hoʻokomo i ka wahie; i ka ECU hoʻomalu i ka solenoid coil o ka wahie injector e e energized, ka magnetic kahua i hanaia e ka solenoid coil e hoʻolele i ka armature , Ke neʻe nei ke kui kui, wehe ke kui kui, a me ka wahie injector injects wahie. ʻO ka maʻamau, ʻo ka hāpai ʻana o ka valve needle injector ma kahi o 0.1mm.
Hōʻike ʻia ke kumumanaʻo o ke kaapuni injector hoʻokele wahie ma ka Figure 1. ʻO ka electromagnetic coil o ka wahie injector e alakaʻi i ʻelua uea, hoʻokahi uea ka mana lako, e hoʻolako ana i ka volta 12V ma hope o ka hoʻohuli ʻia ʻana o ke kī kī, a ʻo ka uea ʻē aʻe. ke kaapuni honua i hoʻomaluʻia e ka mana uila. I ka wa e pono ai ka wahie injector e wehe i ka wahie hoolele, ka uila uila ECU mana i ka grounding o keia laina ma o ka triode, a me ka uila e kahe ana ma ka electromagnetic coil, a me ka wahie injector wehe i ka wahie injection. ʻO kēlā me kēia manawa ke hoʻomalu nei ka ECU i ka flux magnetic o ka injector electromagnetic wire i kapa ʻia ʻo ka wahie injection pulse ākea, aia ma ka laulā o 2 ~ 10ms.
