Igwe mmanụ petrol isii nke ọhụrụ M 256

M256 na-akakwa akara nloghachi Mercedes-Benz na nhazi izizi isii nke ika ahụ. A afọ ole na ole gara aga, isii cylinder ikuku nkeji M272 KE35 na injection n'ime oriri manifolds (KE-kanaleinspritzung) na akụkụ n'etiti cylinder anoghi n'ulo oba nke 90 degrees na M276 DE 35 na kpọmkwem injection (DE-direkteinspritzung) na akụkụ nke A na-edochi ogo 60 n'otu oge ahụ, ụlọ ọrụ bụ isi nke a gbaziri site na injin Chrysler's Pentastar. Onye ga-anọchi nkeji abụọ a na-achọsi ike bụ M276 DELA30 nwere ihe owuwu V6, yana olu na-arụ ọrụ nke lita atọ ma manye jujujujujujujujujujujujuju abu abuo. N'agbanyeghị ndị ikwu na-eto eto nke ikpeazụ, Mercedes ga-anọchi ya na M 256 ogologo-isi engine, na mbụ na a 48-volt eletriki usoro. Isi ọrụ nke ikpeazụ bụ ịkwọ ụgbọ elu igwe eletriki eletrik na-agbakwunye turbocharger (na-eme ihe yiri nke engine 4.0 TDI nke Audi) - ihe ngwọta mbụ dị na mpaghara mmanụ ụgbọala. Ihe eji arụ ọrụ mmalite (ISG), nke etinyere n'ọnọdụ nke ụgbọ elu na batrị lithium-ion, na-eje ozi dị ka isi iyi ike. N'otu oge ahụ, ISG na-arụkwa ọrụ nke ihe mmewere nke sistemu ngwakọ, mana yana voltaji dị ala karịa ihe ngwọta yiri nke gara aga.

N'ezie, ọ bụ ihe dị mkpa nke engine n'onwe ya ma e mere ya dị ka akụkụ nke ya site na mmalite nke ọrụ mmepe na igwe kwụ otu ebe. Site na 15kW nke ike ya na 220Nm nke torque, ISG na-enyere aka na ngwangwa siri ike na oke ọkụ mbụ, yana nnukwu chaja eletrik e kwuru n'elu, na-eru 70rpm na 000ms. Na mgbakwunye, usoro ahụ na-enweta ike n'oge breeki, na-enye ohere ijegharị ọsọ ọsọ na ike eletrik naanị yana ịrụ ọrụ injin na mpaghara dị mma nke nwere ibu dị elu, n'otu n'otu oghere trotul ka ukwuu ma ọ bụ iji batrị dị ka ihe nkpuchi. Na a 300 volt ike ọkọnọ bụkwa nnukwu ndị na-azụ ahịa dị ka mgbapụta mmiri na compressor nke ikuku. N'ihi ihe a niile, M 48 adịghị mkpa usoro dị n'akụkụ iji kwọọ generator, ma ọ bụ ihe mmalite, nke na-ahapụ ohere na mpụta ya. Nke ikpeazụ a na-eji usoro ndochi mmanye na usoro mgbagwoju anya nke ikuku ikuku na-agba gburugburu engine. A ga-ewebata M256 ọhụrụ n'afọ ọzọ na klaasị ọhụrụ.

Ekele maka ISG, a na-echekwa mmalite na generator nke mpụga, nke na-ebelata ogologo engine. The kacha mma okirikiri nhọrọ ukwuu na nkewa nke oriri na iyuzucha usoro na-enye ohere maka a nso ndokwa nke catalyst na usoro ọhụrụ nke ihicha siri ike irighiri (eji ya mere naanị na mmanụ dizel engines).
