ʻO kekahi o nā mea koʻikoʻi, ʻo ia ka valve needle a me ke kino valve needle i hana ʻia me ke kila hili kiʻekiʻe (ʻike nui ʻia ʻo ka nozzle wahie injection a i ʻole ke poʻo hoʻoheheʻe wahie), ua kapa ʻia lāua ʻelua ʻo ka needle valve couple. Ke hana ka injector, ke kiʻekiʻe kiʻekiʻe mīkini diesel aila mai ka injection pump e komo i ka injector ma o ka paipu hui, a laila e komo i ka annular kiʻekiʻe puʻe aila keʻena ma ka waena o ka nila valve kino ma o ka aila inlet channel ma ke kino injector. Hoʻohana ka ʻaila ʻaila ma luna o ka cone kaomi o ka valve needle a hoʻokumu i kahi pahu axial i luna ma luna o ka valve needle. Ke ʻoi aku ka ʻoi aku o ka hoʻopaʻa ʻana ma mua o ka paʻi paʻa ʻana o ka pūnāwai hoʻoponopono kaomi a me ka ikaika friction ma waena o ka lua o ka nila (he liʻiliʻi loa ia). E hoʻoneʻe ʻia ka ʻili o ka nila i luna, ua wehe ʻia ka cone sealing o ka ʻaoʻao haʻahaʻa o ka valve needle mai ke apo conical o ke kino valve needle, a wehe ʻia ka lua injection, i hoʻokomo ʻia ka wahie diesel i loko o ke keʻena kuni. kaomi kiʻekiʻe. I ka pau ana o ka pauma wahie i ka hoolako ana i ka aila, e emi koke ana ke kaomi ana o ka aila ki'eki'e, a e ho'i mai ka pahu kui i ka manawa ma lalo o ka hana a ka puna hooponopono kaomi e pani i ka lua jet. Nui ka helu o nā puka o ka orifice injector (maʻamau 1 ~ 8), liʻiliʻi ke anawaena o ka orifice (maʻamau 0.2 ~ 0.8mm), kiʻekiʻe ke kaomi injection (maʻamau 17 ~ 22MPa), ʻo ka hiki ke hoʻomaʻemaʻe ponoʻī. ʻilihune (maʻalahi ka orifice e hōʻiliʻili i ke kalapona a me ka plug), a ʻoi aku ka maikaʻi o ka kānana diesel. He kūpono ia no ke keʻena hoʻoheheʻe injection pololei e koi ai i ka maikaʻi spray kiʻekiʻe. No ka la'ana, he 0.32mm ka anawaena o ka 5-hole i ho'ohana 'ia ma CA6110-2 diesel engine a he 17.2MPa.
