Opel 1,6 SIDI Turbo Ecotec ʻenekini (125 a me 147 kW)
ʻO ke kaʻa mua loa i loaʻa i ka ʻenekini 1,6 SIDI turbocharged direct injection ʻo ia ka Opel Cascada convertible. Wahi a ka mea hana kaʻa, pono kēia ʻenekini ke alakaʻi i kāna papa e pili ana i ka ʻai, ka hana a me ka moʻomeheu o ka hana.
ʻO ka mīkini ʻaila mua o Opel me ka hoʻoheheʻe ʻia ʻana o ka aila pololei ʻo ia ka 2,2 kW 114 ECOTEC ʻehā-cylinder engine i ka makahiki 2003 ma nā hiʻohiʻona Signum a me Vectra, i hoʻohana ʻia ma hope o ka Zafira. I ka makahiki 2007, ua loaʻa i ka Opel GT convertible ka mua 2,0-lita turbocharged ʻehā-cylinder direct injection engine me 194 kW. I hoʻokahi makahiki ma hope mai, ua hoʻomaka kēia mīkini e hoʻokomo i ka Insignia i ʻelua mau mana me ka mana o 162 kW a me 184 kW. Ua loaʻa i ka Astra OPC hou ka mana ikaika loa me ka mana o 206 kW. Ua hui ʻia nā ʻāpana ma Szentgotthard, Hungary.
ʻO ka 1,6 SIDI engine (spark ignition direct injection = spark ignition direct fuel injection) he cylinder displacement o 1598 cc. E ʻike a, ma kahi o ka injection pololei, ua lako pū me kahi ʻōnaehana hoʻomaka / hoʻōki. Loaʻa ka mīkini i ʻelua mau mana mana 1,6 Eco Turbo me 125 kW me ka torque kiʻekiʻe o 280 Nm a me 1,6 Performance Turbo me 147 kW a me ka torque kiʻekiʻe o 300 Nm. ʻO ka mana haʻahaʻa haʻahaʻa i hoʻopaʻa ʻia ma ke ʻano o ka hoʻohana ʻana i ka wahie, he kiʻekiʻe kiʻekiʻe ma nā haʻahaʻa haʻahaʻa a maʻalahi. Hoʻolālā ʻia ka mana ʻoi aku ka ikaika no nā kaʻa kaʻa ʻoi aku ka makaʻu ʻole i ka loaʻa ʻana o kā lākou makuakāne.
Aia ma ka puʻuwai o ka ʻenekini SIDI ECOTEC Turbo hou he pahu pahu hao hao hou loa e hiki ai ke kū i nā kaomi kiʻekiʻe a hiki i ka 130 bar. I mea e hōʻemi ai i ke kaumaha, hoʻohui ʻia kēia poloka hao me kahi pahu pahu alumini. Hana ʻia ka poloka mīkini me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe ʻana i ka paia lahilahi, e hiki ai ke hoʻohui pono i nā hana like ʻole a me nā mea i loko o ka hoʻolei ʻana, e hōʻemi ana i ka manawa hana. ʻO ka manaʻo o nā mea hoʻololi e maʻalahi ka hoʻohana ʻana i ka ʻenekini hou i nā pae hoʻohālike like ʻole. Hoʻolako pū ʻia nā ʻenekini me nā kumu kaulike, ʻo ia wale nō nā mea i kā lākou papa i kēia manawa. Aia ʻelua ʻāpana kaulike ma ka paia hope o ka poloka cylinder a hoʻokele ʻia e ke kaulahao. ʻO ke kumu o nā kumu hoʻololi kūʻē i ka hoʻopau ʻana i nā haʻalulu i hana ʻia i ka wā o ka hana ʻana o ka mīkini ʻehā-cylinder. ʻOkoʻa nā mana ʻo Eco Turbo a me Performance Turbo i nā piston i hoʻohana ʻia, ʻo ia hoʻi ke keʻena puhi ahi kūikawā i ke poʻo piston. ʻO ke apo piston mua he uhi PVD (Physical Vapor Deposition) e hōʻemi ana i nā poho friction.
Ma waho aʻe o ka hoʻololi ʻana i ka hoʻolālā ʻana, hoʻemi pū ka ʻōnaehana petrol injection in-cylinder i ka hoʻohana ʻana i ka wahie (ʻo ia hoʻi. Aia ka pulupulu a me ka injector i waenakonu o ke keʻena kuni i loko o ke poʻo cylinder e hōʻemi hou i ka nui o waho. Kōkua pū kēia hoʻolālā i ka hoʻomaikaʻi ʻana i ka lokahi a i ʻole ka waiho ʻana o ka hui. Hoʻokele ʻia ke kaʻaahi valve e kahi kaulahao hoʻopaʻa ʻole i ka mālama ʻana, hydraulically tensioned, a ʻo ka pulley rocker arm i loaʻa i ka hydraulic clearance.
Hoʻohana nā ʻenekini 1,6 SIDI i ka turbocharger i kūkulu pono ʻia i loko o ka manifold exhaust engine. Ua hōʻoia mua kēia hoʻolālā iā ia iho me nā ʻenekini Opel ʻē aʻe a ua maikaʻi ma ke ʻano o ka wāwae wāwae a me nā kumukūʻai hana no ka mea ʻoi aku ka maʻalahi i ka hoʻohālikelike ʻana i nā turbocharger Twin-Scroll i hoʻohana ʻia i nā ʻenekini nui aʻe. Hoʻolālā ʻia ka turbocharger no kēlā me kēia mana mana. Mahalo i ka hoʻolālā i hoʻolālā hou ʻia, hāʻawi ka ʻenekini i ka torque kiʻekiʻe a hiki i nā revs haʻahaʻa. Eia kekahi, ua hana ʻia ka hana no ka hoʻopau ʻana i ka walaʻau i makemake ʻole ʻia (whistling, pulsation, leo o ka ea e kahe ana a puni nā lau), me ka mahalo i nā resonator haʻahaʻa a me ke kiʻekiʻe, hoʻomaikaʻi i ka conductivity ea a me ke ʻano o nā ala komo. No ka hoʻopau ʻana i ka walaʻau o ka mīkini ponoʻī, ua hoʻololi ʻia ka paipu exhaust, a me ka uhi manifold valve ma ke poʻo cylinder, kahi i hoʻopili ʻia ai nā mea kaomi kūikawā a me nā sila e kū kūʻē i nā wela kiʻekiʻe o ka turbocharger pili.
