Isku dhafka magnesium iyo aluminium - saameyntee la helay?

Sidii hore loo sheegay, dhismuhu wuxuu ku salaysan yahay baloog ka samaysan isku-dhafka magnesium-aluminium. Xidhiidhka noocan oo kale ah ayaa loo isticmaalay sababtoo ah sifooyinka ugu horreeya ee alaabta la sheegay. 

Waxay leedahay miisaan hoose, si kastaba ha ahaatee, waxay u nugul tahay daxalka waxayna waxyeelleyn kartaa heerkulka sare. Taasi waa sababta loogu daray aluminium, taas oo aad ugu adkaysanaysa arrimahan. Guryaha qaboojiyaha waxay ka samaysan yihiin aluminium, oo daboolaya dibadda. 

Xalalka naqshadeynta ee mooto N52

Naqshadeeyayaashu waxay go'aansadeen inay isticmaalaan kontoroolka koontaroolka elektarooniga ah iyo wakhtiga beddelka valve - nidaamka waxaa loo yaqaanaa laba-VANOS. Cutubyo ka xoog badan ayaa sidoo kale lagu qalabeeyay saddex heer oo kala duwan oo dhererka qaadashada ah - DISA iyo nidaamka Valvetronic.

Alusil waxaa loo isticmaali jiray xargaha dhululubada. Waa aluminium-silicon daawaha hypereutectic. Qaab dhismeedka aan dabada lahayn ee maaddadu waxay haysaa saliid waana dusha sare ee ku habboon. Alusil waxa uu bedelay Nikasil oo hore loo isticmaali jiray, kaas oo sidoo kale meesha ka saaray dhibaatooyinka daxalka marka la isticmaalayo shidaal baaruud ah. 

Naqshadeeyayaashu waxay kaloo isticmaaleen kaamiro godan si ay u yareeyaan miisaanka, iyo sidoo kale bamka biyaha korontada ku shaqeeya iyo bamka saliida barokaca ee doorsooma. Matoorka N52 waxa uu ku rakiban yahay nidaamka xakamaynta ee Siemens MSV70 DME.

Cilada matoorka n52

Cutubka waxa loo arkaa mid guulaystay. Tani ma khusayso moodooyinka lix-dhululubo ee lagu rakibay 328i iyo 525i, kuwaas oo dib loo soo celiyay sababtoo ah cilad naqshadeed oo soo noqnoqotay taasoo keentay wareeg gaaban oo ah kuleyliyaha hawo-mareenka. 

Dhanka kale, dhibaatooyinka caadiga ah waxaa ka mid ah fashilka nidaamka VANOS, qalabeeyayaasha waalka biyaha, ama bamka biyaha oo xumaada ama waxyeelo soo gaarto heerkulbeegga. Isticmaalayaashu waxay sidoo kale fiiro gaar ah uyeeleen daboolka waalka daadanaya, guryaha shaandhada saliidda, ama shaqo la'aanta aan sinnayn.
