HOOLAHA HUA

I ka makahiki 2001, ua hoʻomaka ka ʻenekini diesel 2.5-lita ma nā minibus H-1 a me Starex. Ma mua o kēia, ua hana ʻo Hyundai-Kia i nā clones Mitsubishi 4D56, a ʻokoʻa loa ka ʻenekini hou: ʻaʻole ia he ʻenekini vortex-chamber diesel, akā he hui hou loa me kahi ʻōnaehana Common Rail. Aia kahi poloka hao no 4 cylinders, he poʻo alumini 16-valve me nā mea hoʻokiʻekiʻe hydraulic, kahi hoʻokele manawa ʻekolu kaulahao nani, kahi intercooler a, ʻoiaʻiʻo, he poloka o nā kumu kaulike.

I ka huina, he ekolu mau hanauna o ia mau engine diesel, no ka EURO 3, 4 a me 5.

1. ʻO ka hanauna mua o ka hui i hoʻolako ʻia me kahi ʻōnaehana Bosch Common Rail me ke kaomi a hiki i ka 1360 bar, kahi turbine Garrett GT1752LS a hoʻomohala i 116 - 140 hp, a me 314 - 343 Nm o ka torque.

2. Ua hoʻokomo ʻia ka lua o ka hanauna i ka makahiki 2006, me kahi ʻōnaehana 1600 bar Bosch CR a me BorgWarner BV43 variable geometry turbine, hoʻonui ka mana i 170 hp a me 392 Nm.

3. Ua puka mai ke kolu o ka hanauna ma 2011, eia kekahi CR Delphi okoa ma 1800 bar a me ka MHI TD03L4 turbine. Ua hoʻohaʻahaʻa ʻia ka lākiō kōmike mai 17.7 a 16.4, ua mau ka mana, a ua hoʻonui ʻia ka torque i 441 Nm.

Ua hoʻokomo ʻia ka ʻenekini ma:

Hyundai Starex 1 (A1) ma 2001 – 2007;

Nā hemahema o ka mīkini Hyundai D4CB

I ka makahiki 2008 a me 2009, ua hoʻololi ʻia ka ʻenekini ma lalo o ka palapala hōʻoia: ua haki ke koʻokoʻo hoʻohui ma muli o nā kī kīnā ʻole. I nā ʻenekini ma hope o ka makahiki 2011 me Common Rail Delphi, hoʻokele pinepine ka pahu wahie i nā ʻāpana.

ʻO ka hemahema kaulana loa o kēia ʻenekini diesel, ʻo ia ka pau ʻana o nā mea holoi keleawe ma lalo o nā nozzles, kahi e alakaʻi ai i ka coking wikiwiki o ka mīkini me nā hopena kaumaha loa.

ʻO kekahi pilikia maʻamau me ia ʻano kaʻa kaʻa ʻaila. Manaʻo ʻia e nānā i kēlā me kēia manawa a i ʻole i manaʻo ʻole hiki ke hoʻohuli i nā laina laina.

ʻO ka mīkini hoʻoili kinoea he ʻekolu mau kaulahao a ʻo ka nāwaliwali loa ma ʻaneʻi ʻo ia ka mea haʻahaʻa, ka mea e hoʻohuli ai i ka pauma aila a me nā mea kaulike. Me kona haki ʻana, ua haki pū ke kaulahao manawa nui.

ʻO nā laina crankshaft, nā mea hoʻokiʻekiʻe hydraulic, ka ʻōnaehana hoʻokele vacuum a me ka ʻōnaehana hoʻololi geometry turbocharger a me ka valve EGR ʻaʻohe kumu kiʻekiʻe loa ma aneʻi.
