ʻO ke kaomi kiʻekiʻe o ka wahie wai i ʻike ʻia e ka ʻōnaehana kaʻa maʻamau e koi i ka pololei kiʻekiʻe i ka wahie
ka nui i hāʻawi ʻia i loko o ke keʻena kuni e ka injector. I kēia manawa aia ʻelua ʻano nui o nā injectors
hoʻohana maʻamau ʻia no ka ʻenekini hoʻomāmā a me ka ʻenekini hoʻāla: electromagnetic a
piezoelectric. ʻOiai ʻoi aku ka haʻahaʻa o ke kaomi wahie hana ma nā ʻōnaehana injection gasoline
hoʻohālikelike i ka diesel wahie nenoai, akā, injector wehe manawa ua aneane like no na ano elua o
kūkulu hale. ʻO kēlā ʻoiaʻiʻo e hana like nā koi no nā mea hoʻokomo CI a me SI. Pono kēia mau mea hana
ʻike ʻia e ka pane wikiwiki ʻana i nā hōʻailona mana kūpono no ka hana wehe a pani ʻana.
ʻO Payri et al. [1] noiʻi i ka mana o ka ʻenehana electromagnetic a me ka piezoelectric ma
kaʻina hana hoʻoheheʻe no nā piezoelectric indirect-acting a me solenoid injectors. Ma kēlā ʻano hydraulic
ua hoʻomākaukau ʻia nā hiʻohiʻona no nā hoʻolālā ʻelua a laila hoʻohālikelike ʻia kekahi me kekahi. Ma kēia noiʻi ʻana ka
Ua hoʻohana ʻia ka hōʻailona o ka wahie ma muli o ke ʻano Bosch. Ua hōʻike ʻia nā hopena i loaʻa i ka hoʻokō wikiwiki ʻana o
hoʻohālikelike nā piezo-injectors i nā solenoid. ʻO ke ʻano o ka liʻiliʻi o kā lākou lohi hydraulic. ʻO ka
Ua hoʻonui ʻia nā ʻokoʻa me ka like ʻole o ke kaomi injection. Nānā lua mai
ʻO ia hoʻāʻo ʻo ia ka wikiwiki kahe o ka wahie no ka piezo-injector i hoʻohālikelike ʻia i ka hoʻolālā ʻē aʻe me nā mea like
anawaena puka.
Ua mālama ʻia nā noiʻi like e Yu et al. [2], akā, ma ia hihia, ua koho ʻia nā wahie no ka hoʻokolokolo ʻana
ʻaila hinu a me ka wahie diesel. Ma muli wale nō o nā hōʻailona hoʻomalu a me ka hoʻololi ʻana o ke kahe wahie mai ka injector
nozzle, ua loaʻa ka hoʻopaneʻe ʻana i ka manawa o ka wehe ʻana o ka uila. ʻO nā waiwai o kēia
ua kūʻokoʻa ka ʻokoʻa i ke kaomi injection (ma kēia hihia 60 a me 100 MPa) a me ka lohi
ʻO nā manawa he 0.45 ms no ka piezo- a me 0.55 ms no ka injector solenoid. Eia hou, kahe wikiwiki
mai ka injector nozzle no ka haʻahaʻa haʻahaʻa i ʻike ʻia. Hāʻawi kēlā ʻoiaʻiʻo i nā pōmaikaʻi nui i
ka hana ʻenekini puhi ahi e like me ka ʻoi aku ka maikaʻi o ka atomization a me ka evaporation o ka wahie. Ua hoʻohana nā mea kākau
