Denso wahie injector

(1) E hoʻomau i ka hoʻohana ʻana a me ka hoʻomaikaʻi ʻana i ka ʻōnaehana orifice control e hōʻemi hou i ka wā hoʻoheheʻe wahie. Hoʻohālikelike ʻia me G4S, hoʻomaikaʻi ʻo G4.5S i nā hiʻohiʻona hydraulic transient o ka valve ala ʻelua i ka wā e wehe ʻia ai ka orifice mana hoʻoneʻe, i hiki ai ke kaomi i loko o ke keʻena hoʻomalu a mālama i kahi pae haʻahaʻa, i hiki ke wikiwiki i ka valve needle aʻe. pani ʻia. hāmama. Ua manaʻo ʻia hiki ke hiki i ka 0.1ms i ka wā e hiki mai ana ka wahie injection interval o G4.5S, a ʻo ka hā o ka piezoelectric injector G4P ʻaʻole hiki ke ʻike i ka wā ʻole wahie.
(2) E ho'ēmi i ka puka nozzle anawaena o ka wahie injector a hoʻomaikaʻi i ke ʻano o ka puka nozzle, a laila e hoʻomaikaʻi ai i ka diffusibility o ka spray. I mea e hoʻokō ai i ka diffusion kiʻekiʻe a me ke komo haʻahaʻa ma ke kaomi kaʻa haʻahaʻa haʻahaʻa, a i ka manawa like e hoʻokō ai i ke komo ikaika like ʻana i ke kaomi kaʻa kaʻa kiʻekiʻe e like me nā injectors wahie maʻamau, ua hoʻomohala ʻo Denso Corporation i kahi nozzle me kahi lākiō o 0.1x0.8 mm. ʻO ka puka pōkole a i ʻole ka nozzle ʻano kūikawā (CDS, Controlled Diffusive Spray Nozzle) e hoʻokō i ka hopena diffusion i makemake ʻia.
(3) E hoʻomaikaʻi i ka hana i-art e ʻike i ka ʻike o ka pre-injection a me ka nui o ka injection injection. I ka manawa like, hiki ke loaʻa ka hoʻololi ʻana o ka wikiwiki kani ma ke ana ʻana i ka pae o ka nalu kaomi ma hope o ka pau ʻana o ka injection, i loaʻa ai ka nui o ka wahie. A laila, loaʻa ka viscosity kinematic ma o ka pilina i ʻike ʻia ma waena o ka helu n-cetane o ka wahie a me ka pilina ma waena o ka density a me ka viscosity dynamic, i ʻike ai i ka hoʻoponopono ʻana i ke kahe kahe o ka wahie i hoʻokomo ʻia, etc.
