E ho'āʻo i nā ʻenekini Mercedes hou: Mahele III - Petrol

Hoʻomau mākou i ka moʻo no nā ʻōnaehana loea kiʻekiʻe i ka laulā o nā anakuhi

ʻO ka ʻenekini petrol hou ʻeono-ʻenekini hou M 256

Kaha pū ka M256 iā Mercedes-Benz i ka hoʻi ʻana i ka lālani kumu o nā paukū ʻeono. I kekahi mau makahiki i hala aku nei, ua hoʻololi ʻia nā ʻāpana ea ʻeono-paukū M272 KE35 me ka ʻume i nā manifold komo (KE-kanaleinspritzung) i ka manawa like me ka huina ma waena o nā lālani paukū o 90 kekelē a me M276 DE 35 me ka hoʻopili pololei (DE-direkteinspritzung ) me kahi kihi o 60 i noi ʻia mai nā ʻenekini Pentastar o Chrysler. ʻO ka hope o nā ʻāpana ʻelua i makemake nui ʻia ʻo M276 DELA30 me ka hoʻolālā V6, me kahi neʻe ʻana o ʻekolu liters a koi ikaika ʻia me nā turbocharger ʻelua. ʻOiai ʻo ka ʻōpio pili o ka hope, e pani ʻo Mercedes iā ia me ka ʻenekini ʻeono-paukū M 256, i hoʻolako mua ʻia me ka ʻōnaehana uila 48-volt. ʻO ka hana nui o ka hope ke hoʻokau i ka compressor mīkini uila e hoʻopiha ana i ka turbocharger (e like me ka ʻenekini 4.0 TDI a Audi) - ʻo ia ka hopena mua ma ka ʻāpana ʻaila. ʻO ke kumuwaiwai ka Integrated Starter Generator (ISG), hoʻonoho ʻia ma kahi o ka flywheel a me ka pakuhi lithium-ion. I ka manawa like, hoʻokani pū ka ISG i ke ʻano o kekahi mea o ka ʻōnaehana hybrid, akā me ka uila i ʻoi aku ka haʻahaʻa ma mua o nā hāʻina like i hala.

ʻO ka ʻoiaʻiʻo, ʻoi aku ka nui o ka mea hoʻohui o ka mīkini ponoʻī a ua hoʻolālā ʻia ma ke ʻano he ʻāpana o ia mea mai ka hoʻomaka ʻana o ka hana hoʻomohala ʻana i ke kaʻa. Me kona 15kW o ka mana a me 220Nm o ka torque, kōkua ka ISG i ka hoʻopuka ʻana i ka wikiwiki wikiwiki a me ka torque kiʻekiʻe mua, me ka supercharger uila i ʻōlelo ʻia ma mua, hiki i 70rpm i 000ms. Eia kekahi, hoʻihoʻi ka ʻōnaehana i ka ikehu i ka wā o ka braking, e ʻae i ka neʻe ʻana o ka wikiwiki me ka mana uila wale nō a me ka hana ʻana o ka ʻenekini ma kahi ʻoi aku ka maikaʻi me ka haʻahaʻa kiʻekiʻe, ʻoi aku ka nui o ka wehe throttle a i ʻole ka hoʻohana ʻana i ka pākaukau ma ke ʻano o ka hoʻouka ʻana. Me ka lako mana 300 volt he mau mea kūʻai nui hoʻi e like me ka paila wai a me ka compressor o ka air conditioner. Mahalo i kēia mau mea a pau, ʻaʻole pono ka M 48 i kahi mīkini peripheral e hoʻokele i ka generator, ʻaʻole hoʻi i ka mea hoʻomaka, no laila e hoʻokuʻu ana i kahi ākea ma waho. Noho ʻia ka hope e ka ʻōnaehana hoʻopihapiha hoʻopihapiha me kahi ʻōnaehana paʻakikī o nā ʻea ea e hoʻopuni ana i ka mīkini. E hoʻolauna ʻia ka M256 hou i ka makahiki aʻe i ka S-Class hou.

Mahalo i ka ISG, mālama ʻia ka mea hoʻomaka waho a me ka generator, e hōʻemi ana i ka lōʻihi o ka mīkini. ʻO ka hoʻolālā maikaʻi loa me ka hoʻokaʻawale ʻana o nā ʻōnaehana intake a me nā ʻōnaehana hoʻopau e hiki ai ke hoʻonohonoho kokoke i ka catalyst a me ka ʻōnaehana hou no ka hoʻomaʻemaʻe ʻana i nā ʻāpana paʻa (hoʻohana ʻia i nā mīkini diesel wale nō). I kona mana mua, he mana ka mīkini hou a hiki i ke ki'eki'e o nā mīkini ewalu cylinder i kēia manawa me kona 408 hp. a me 500 Nm, me ka 15 pakeneka ho'ēmi i ka wahie hoʻohana a me ka hoʻokuʻu 'ana i ka hoʻohālikelike 'ia i ka M276 DELA 30. Me kona neʻe 'ana o 500 cc no ka cylinder, ka hou waeia i ka mea maikaʻi loa, a e like me BMW 'enekinia, displacement e like me ka mea o ka. ʻelua lita o ka ʻenekini diesel i hoʻolauna ʻia i ka makahiki i hala a me ka ʻenekini ʻaila ʻehā pahu hou ʻelua lita.

ʻO ka ʻenekini 4.0 hou hou, ʻoi aku ka liʻiliʻi akā ʻoi aku ka ikaika

I ka hōʻike ʻana i ka hana a kāna hui i ke ʻano o ka M 176 hou, ua kamaʻilio ke poʻo o ke keʻena ʻenehana ʻewalu paukū ʻoloka, ʻo Thomas Ramsteiner, me ka hoʻopā o ka haʻaheo. "ʻO kā mākou hana ka paʻakikī loa. Pono mākou e hana i ʻenekini ʻewalu paukū i hiki ke komo ma lalo o ka pale o ka C-Class. ʻO ka pilikia, ʻo nā hoa hana e hoʻomohala ana i nā ʻenekini ʻehā a ʻeono-ʻenekini he nui ka manawa e hoʻolālā maikaʻi ai i nā mea e like me ka lawe ʻana a me nā ʻōnaehana hoʻopau a me ka ʻoluʻolu o ka ea. Pono mākou e hakakā me kēlā me kēia kenimika cubic. Ua hoʻokau mākou i nā turbocharger ma loko o nā paukūʻoloka a me nā mea hoʻoulu ea i mua o lākou. Ma muli o ka hōʻiliʻili o ka wela, hoʻomau mākou i ka holo o coolant a hoʻomau i nā pā ma hope o ka pau ʻana o ka ʻenekini. I mea e pale ai i nā ʻenekini, nā insulated exhaust a me nā turbocharger i insulated thermally. "

He ʻoi aku ka liʻiliʻi o ka M 176 ma mua o ka M 278 (4,6 lita) a he derivative o nā ʻāpana AMG M 177 (Mercedes C63 AMG) a me M 178 (AMG GT) me nā huahana i ka laulā o 462 hp. a hiki i 612 hp ʻAʻole e like me ka mea hope, i hōʻuluʻulu ʻia ma ke kumu hoʻokahi kanaka-hoʻokahi-engine ma Affalterbach, ʻoi aku ka laulā o ka M 176, hōʻuluʻulu ʻia ma Stuttgart-Untertürkheim a loaʻa iā ia ka mana mana o 476 hp, kiʻekiʻe torque o 700 Nm a e pau i ka 10 pakeneka emi wahie. ʻAʻohe mea liʻiliʻi, ma muli o ka hiki ke hoʻopau i ʻehā o nā cylinders ʻewalu ma kahi haʻahaʻa ʻenehana. Hana ʻia ka hope me ke kōkua o ka CAMTRONIC variable valve timing system, kahi e hoʻololi ai ka hana o nā cylinders ʻehā i ke ʻano o ka ukana ʻoi aku ka nui me kahi kīwaha ākea ākea. ʻEwalu mea hoʻokele e hoʻoneʻe axially i nā mea me nā kāmela i pau ka wehe ʻana o nā kiwi o ʻehā o lākou. Hana ʻia ke ʻano hana ʻehā-cylinder i nā mode rev mai 900 a 3250 rpm, akā inā makemake ʻia ka mana hou aʻe, hoʻololi ia i loko o nā milliseconds.

ʻO ka pendulum centrifugal kūikawā ma ka huila lele ka hana o ka hoʻohaʻahaʻa ʻana i nā pūʻali haʻalulu ʻehā i ka hana 8-cylinder a me nā pūʻali haʻalulu lua i ka hana 4-cylinder. Hoʻomaikaʻi ʻia ka maikaʻi Thermodynamic e ka hui ʻana o ka biturbo charging a me ka hoʻokō pololei ʻana me kahi injector kūloko (e nānā i ka pahu) a me ka uhi NANOSLIDE. Hāʻawi ia i nā inikini he nui no ka hui ʻana maikaʻi, a ua hana ʻia ka mīkini paʻa paʻa i nā alumini alumini a kū i ke kaomi o 140 bar.

ʻEhā-ʻenekini petrol M 264 me ka pōʻaiapuni ʻo Miller

ʻO ka petrol hou ʻehā mau paukū turbocharger mai ka hanauna ʻenekini like me ka M 256 a he ʻano like kona paukūʻolokaʻa. Wahi a Nico Ramsperger mai ka ʻenekini ʻehā paukūʻolokaʻa, hoʻokumu ʻia ia i ka M 274 hou loa, a mākou i kamaʻilio mua ai. I ka inoa o ka wikiwiki o ka ʻenekini, hoʻohana ʻia kahi turbocharger mokulele lua, e like me ka AMG M M 133, a ʻoi aku ka mana o ka lita ma kahi o 136 hp / l. E like me ka nui o M 256, hoʻohana ia i kahi ʻōnaehana lako 48-volt, akā ʻokoʻa ia mea he kūwaho, kāʻei ʻia a hana ʻia ma ke ʻano he generator hoʻomaka, e kōkua ana i ke kaʻa e hoʻomaka a hoʻonui a ʻae i ka hoʻololi maʻalahi o ka pae hana. Hāʻawi ka ʻōnaehana hoʻokaʻawale kinoea hoʻololi i ka hana ma kā mākou pōʻai ʻo Miller.
