EMIKINIA HOʻOPIʻI no: ʻEnekini Mercedes M270
HOOLAHA HUA
ʻO nā mīkini ʻenekini Mercedes M270 me ka nui o 1.6 a me 2.0 lita i hana ʻia mai 2011 a 2019 a hoʻokomo ʻia ma nā hiʻohiʻona me kahi mīkini transverse, e like me ka papa A a me ka papa B. ʻO nā ʻāpana like no nā kaʻa me kahi ʻenekini longitudinal ʻo index M274.
R4 Mercedes engines: M102, M111, M133, M139, M166, M200, M254, M260, M264, M266, M270, M271, M274, M282.
I ka makahiki 2011, ua hoʻomaka ʻia kahi pūʻulu hou o 1.6 a me 2.0 lita o ka mana ʻaila, i ʻokoʻa i ka piston stroke, a ua loaʻa i nā ʻenekini kekahi mau koho hoʻoikaika. ʻO ka hoʻolālā he mea hou loa ia: kahi pahu alumini 4-cylinder me nā lima lima hao a me ka lole hoʻoluʻu hāmama, kahi poʻo cylinder 16-valve alumini me nā mea hoʻokiʻekiʻe hydraulic, kahi ʻōnaehana hoʻoheheʻe wahie me nā piezo injectors, nā mea hoʻololi i nā pahu ʻelua, kahi IHI AL0070 a i ʻole IHI AL0071 turbocharger me ka ea intercooler a me ke kaulahao manawa. Eia kekahi, ʻo ka pauma aila hoʻololi hoʻololi a me ka thermostat uila.
Ua hoʻolako ʻia nā hoʻololi ʻenehana 1.6-lita me kahi ʻōnaehana hoʻokomo Camtronic, a ua loaʻa i nā mana 2.0-lita kahi ʻano hoʻohālikelike Lanchester e hōʻemi i nā haʻalulu.

Nā hemahema o ka mīkini Mercedes M270
I nā kaʻa a hiki i ka makahiki 2014, ua hāʻule koke nā regulators phase a hoʻomaka e haki, a laila ua hoʻonui ʻia a hoʻomaka ka pilikia ma hope, akā ʻaʻole naʻe i nalowale. ʻAʻohe kumu kiʻekiʻe o ke kaulahao manawa, hoʻololi pinepine ʻia i kēlā me kēia 100-150 tausani km.
Ma nā ʻenekini o kēia ʻohana, kaomi ʻia ka disk impulse ma luna o ka camshaft a neʻe mālie i kēlā me kēia hoʻomaka. ʻO ke kaulahao ʻōniʻoniʻo ʻoi aku ka wikiwiki o ke kaʻina hana. ʻO ia ke kumu i pilikia ai ka hoʻomaka ʻana o ka ʻenekini a hiki i ka pau ʻole.
I ka makahiki 2015, ua loaʻa i nā mana mana o kēia pūʻulu kahi firmware ʻē aʻe a lilo i ʻoi aku ka waiwai, akā ua kāhea ʻia ke hoʻololi ʻana i nā piston i luku ʻia ma muli o ka detonation ua ua koke. ʻO ka wahie haʻahaʻa haʻahaʻa e hōʻemi nui i ka waiwai o nā injectors piezo injection pololei.
Pono e nānā pono i ke ʻano o ka ʻōnaehana hoʻoluʻu o kēia ʻāpana, no ka mea ke alakaʻi wikiwiki nei ke poʻo cylinder ma aneʻi a mai kahi overheating lōʻihi. Hoʻonui ʻia kēia pilikia e ka loaʻa ʻole o ka thermostat hilinaʻi a me ka pā wai.
Loaʻa pinepine ʻia nā leaks ma muli o ka hewa o kahi pahu hoʻoheheʻe crankcase i hoʻopaʻa ʻia, a mai lalo hoʻi o ka pahu hoʻololi wela a i ʻole ma ka sila ʻaila crankshaft mua. Ma muli o ka haki ʻana o ka uwila, e kau ana ka valve displacement oil pump valve, e kahe pū ana nā paipu wahie, hopu ka turbine actuator, a hoʻopaʻa koke ka adsorber.
