ʻO ke ʻano a me ke kumu o ka injector

ʻO ka injector wahie he mea kikoʻī me ka pololei machining kiʻekiʻe, 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 i ka injector wahie 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 hookuke i ka armature , Ke neʻe nei ke kui kui, wehe ka nila, 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 mau uea, hoʻokahi uea ka mana lako, e hoʻolako ana i ka uila 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 injection, ka uila mana wae 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.
