ʻO ka hui pū ʻana o ka pahu hoʻoheheʻe ʻaila maʻamau F00VC01386 no nā Injectors 0445110387 & 0445110388

ʻO ka nānā ʻana o nā mokuʻāina transient o nā injectors CI engine me ka hoʻohana ʻana i nā ʻano optical(MĀhele 7)

No nā injectors ʻelua, ua manaʻo ʻia ka lohi o ka pane ʻana i ka mīkini a he 0.012 ms no ka piezo- a me 0.016 no ka injector solenoid.E like me ka hōʻailona kukui diode ma ke kiʻi like ma hope o ka hoʻomaka ʻana o kēlā me kēia ana, hiki ke ʻōlelo ʻia he kūpaʻa a hiki ke hana hou ʻia nā ana.Hōʻike ka Figure 5 i ka manawa pōkole no nā ʻano injectors ʻelua, e like me ka mea i ʻōlelo ʻia ma ke ʻano noiʻi.ʻO kēia manawa he 0.2 ms a me 0.3 ms no ka piezo- a me ka solenoid injector, kēlā me kēia.

Ma ka pakuhi no ka piezo-injector, ua hōʻike ʻia ke ʻano e wikiwiki ai i ka hoʻopiʻi ʻana me ke kaomi kiʻekiʻe i loko o ke keʻena.No Pinj = 60 MPa wale nō ka ʻokoʻa o kēia ʻano, akā hiki ke hoʻololi ʻia e nā kūlana maʻamau.Ke hana nei ka solenoid injector ma ke ʻano hou aʻe a ʻaʻole i hoʻololi koʻikoʻi ke kaomi hope i ka manawa lohi.I kēlā hihia, ʻo ke kaomi injection ka mea i wikiwiki i ka injection, ʻoiai ua ʻike mua ʻia no ka piezo-injector.ʻO ka mea kūpono e haʻi ʻia ʻo ia ka ʻoiaʻiʻo, ʻo nā hopena no ka solenoid injector mai Pinj ma luna o 60 MPa i ka nui o nā hihia he ʻokoʻa i ka ± 1 kiʻi wale nō, no laila ma ke ʻano o ke ana pololei ʻana pono lākou e mālama ʻia ʻaʻohe ʻokoʻa.ʻO Piezo-injector ma nā haʻahaʻa haʻahaʻa i loaʻa ka lohi haʻahaʻa ma mua o ka electro-injector, akā me ka piʻi ʻana o ke kaomi i hoʻohuli ʻia.Pono e hoʻomaopopo ʻia he hoʻolālā kahiko ka piezo-injector: ua hoʻololi ka electromagnetic injector i ka piezo-injector i nā hoʻolālā hana.

Hōʻike ʻia nā hopena o ka hoʻopaneʻe ʻana no ka lōʻihi a me ka lōʻihi o ka injection ma ka helu 6 a me ka helu 7.Hiki ke loiloi ʻia ka hana piezo-injector ma ke ʻano maʻamau.Ma ke kumu o ka hoʻohālikelike hopena, hiki ke ʻōlelo ʻia, ʻoi aku ka nui o ka mana o ke ea (back-pressure) i ka lohi a ʻo ka hopena o ke kaomi wahie he marginal.Loaʻa nā hopena like loa no nā injectors solenoid, akā i kēia hihia, ʻo ka hopena nui loa i ka hoʻopaneʻe ʻana i ka hoʻopaneʻe ʻana i ke kaomi wahie a ʻaʻole hiki ke hoʻololi ʻia ka mana o ke ea.
