Nā palapala noiʻi o nā turbocharger

I ka honua, ʻo ka pahuhopu nui ka hoʻomaikaʻi ʻana i ka ʻoihana wahie me ka ʻole o nā ʻālana e pili ana i nā pae hana ʻē aʻe. Ma kahi hana mua, hōʻike ʻia kahi haʻawina hoʻohālikelike vaned diffuser e hiki ke hoʻomaikaʻi maikaʻi i nā wahi hana kūpono i ke kumu kūʻai o ka laulā palapala ʻāina. ʻO ka hoʻoholo ʻana mai nā hopena i hoʻolālā ʻia nā geometries ʻekolu me ka paʻakikī e pili ana i nā diffuser vaned. Hōʻike nā hualoaʻa mai ke kahua hoʻāʻo kinoea wela a me ka rig hoʻāʻo ʻenekini e hiki i nā ʻōnaehana āpau ke hoʻonui i ka pono o ka compressor a pēlā e hoʻomaikaʻi ai i ka hoʻokele wahie ma ka pae hoʻokele nui o nā mīkini kaumaha.

Hōʻike ʻia nā pilikia hou e ka pono no ka lōʻihi kiʻekiʻe, ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana transient maikaʻi o ka mīkini. No laila, ʻo ka hoʻolālā ʻana o ka ʻōnaehana compressor he hoʻololi mau ia ma waena o ka pono kiʻekiʻe, kahi ākea palapala ākea, haʻahaʻa haʻahaʻa o ka impeller a me ka lōʻihi kiʻekiʻe e alakaʻi ana i nā pae compressor me nā poho aerodynamic koʻikoʻi i ke kaʻa kaʻa nui o nā kaʻa lōʻihi. ka emi ana o ka wahie. ʻO ka hoʻoholo ʻana i kēia pilikia koʻikoʻi o ka hoʻolālā compressor ma ka hoʻokomo ʻana i kahi geometry variable hiki ke alakaʻi i ka hōʻemi ʻana i nā kumukūʻai āpau o ke kuleana ʻo ia ka wahi kūʻai mua e pili ana i nā mīkini hana kaumaha. Ma waho aʻe o nā valve recirculation i hoʻohana ʻia i nā turbocharger kaʻa kaʻa, ʻaʻole i loaʻa i nā mea hoʻoheheʻe me nā geometry ʻano like ʻole i ko lākou ala i ka hana hana ʻoiai ua hana ʻia ka noiʻi hohonu ma kēia kahua.

Ua hoʻomohala ʻia ʻekolu mau compressors me ka pahuhopu o ka hoʻomaikaʻi ʻana i ka hoʻokele waiwai o nā ʻenekini koʻikoʻi ma ke kahua kaʻa nui me ka ʻole o ka deteriorations e pili ana i ka mana helu, ka piko kiʻekiʻe, ke kūpaʻa a me ka lōʻihi. Ma kahi hana mua, ua loaʻa nā koi o ka mīkini e pili ana i ka pae compressor a ʻike ʻia nā wahi hana compressor kūpono loa. ʻO ke kaʻa kaʻa nui o nā kaʻa kaʻa lōʻihi e pili ana i nā wahi hana ma nā ratio kaomi kiʻekiʻe a me nā kahe haʻahaʻa haʻahaʻa. ʻO nā poho aerodynamic ma muli o nā kihi kahe nui loa i ka diffuser vaneless e pāʻani i kahi kuleana nui i kēia pae hana.
