ʻO Diesel Fuel Injector 456-3493 no ka Caterpillar C9.3 CAT Truck Engine Spare Parts

ʻO ka hoʻoheheʻe ʻana i loko o kahi injector diesel hana kiʻekiʻe - kahi hoʻokolohua a me ka noiʻi CFD (mahele 1)

ʻĀpana.

Ua hoʻohana ʻia kahi hui ʻana o ka simulation a me nā ʻenehana hoʻokolohua kūikawā no ka noiʻi ʻana i ka kahe transient a me ka cavitation phenomena o kahi mea hoʻomalu i loko o kahi injector diesel hana kiʻekiʻe. Ua kiʻi ʻia ka ʻano cavitation dynamic ma kahi ʻano hoʻohālike nui, a laila hoʻohana ʻia e hoʻomohala a hōʻoia i kahi kumu hoʻohālike CFD turbulence holomua me ka Large Eddy Simulation. Hoʻohana ʻia kēia mau ʻenehana i loko o Delphi e loaʻa ai ka ʻike a hoʻopaʻa i ka hana injector i ka nui maoli.

ʻO ka injector diesel ka mea koʻikoʻi loa i ka hoʻokō ʻana i ka hana ʻenekini premium me nā haʻahaʻa haʻahaʻa. No laila, pono e hoʻomalu ʻia nā injectors no nā mīkini hana kiʻekiʻe me ka pololei. ʻO ka hopena, pono e hoʻolālā a hana ʻia nā valve control hydraulic a me nā puka me ka pololei kiʻekiʻe, a ʻo ka hoʻomaopopo ʻana i kā lākou ʻano kumu e hāʻawi i kahi haʻawina koʻikoʻi i ka hoʻolālā a me ka hoʻoponopono maikaʻi. Hoʻohana ʻo Delphi i kahi hui o ka simulation a me nā ʻenehana hoʻokolohua kūikawā e noiʻi i nā ʻano kahe o kēia mau mea.

E like me nā mea hou a pau, kahi High Performance Diesel Injector ma lalo o ka hoʻomohala ʻana ma Delphi ke kumu o ka hana simulation. ʻO ka hoihoi nui i kēia pepa, ʻo ia nā noiʻi CFD o nā hana mana hydraulic.

He kumuhana kamaʻāina ka cavitation kahe i nā mea hana hoʻoheheʻe diesel; ʻO ka ʻike hoʻokolohua mua i hōʻike ʻia ʻaʻole hiki i ka hana hoʻohālikelike ʻo Reynolds-Averaged Navier-Stokes (RANS) ke hāʻawi i nā hopena kūpono no ka hana cavitation dynamic. No laila ma waho aʻe o ka hana CFD, ua kauoha ʻia nā hiʻohiʻona nui (LSM) o nā ʻāpana like ʻole o nā hana mana hydraulic. ʻO ka hoʻohana ʻana i nā hiʻohiʻona akaka o nā kiwi hoʻomalu a me nā puka i nā unahi i hoʻonui nui ʻia e hiki ai ke hoʻomaopopo i ka hana hydraulic [1] hiki ʻole ke hoʻokō me nā ʻenehana ʻē aʻe. He kūʻokoʻa kūʻokoʻa ka hana hydraulic ma nā unahi āpau e lilo i mea hana hoʻomohala [2].
