Waqtigan xaadirka ah, waxaa jira laba nooc oo waaweyn oo matoorada baabuurta ah: mishiinnada birta ah iyo matoorada aluminiumka ah. Hadaba labadan matoor keebaa ugu fiican in la isticmaalo? Waa maxay farqiga u dhexeeya labada matoor? Dhab ahaantii, ku dhawaad dhammaan qalabka madaxa dhululubada mishiinka waxay ka samaysan yihiin aluminium, sababtoo ah madaxyada aluminiumku waxay leeyihiin waxqabadka ugu fiican ee kuleylka. Madaxa dhululubada mishiinka birta kabka ah dhab ahaantii waa aluminium aluminium ah, laakiin block-ga dhululubada waa bir.
Marka la barbardhigo mishiinka aluminium-ka oo dhan, baloogga cilinder-ka ee mishiinka kabka-birta waxa uu leeyahay awood kulayl xoog badan, kaas oo aad ugu habboon kordhinta awoodda mishiinka. Tusaale ahaan, iyada oo la raacayo saamaynta turbocharging, mishiinka kabka birta ah ee 1.5L ayaa dhab ahaantii gaari kara baahida koronto ee 2.0L; halka mishiinka aluminiumka ah oo dhan aanu buuxin karin shuruudahan. Hadda, kaliya dhowr baabuur oo heer sare ah ayaa isticmaala matoorka aluminiumka ah.
Intaa waxaa dheer, dhammaan mishiinnada aluminiumku waxay u nugul yihiin fal-celinta kiimikada ee biyaha inta lagu jiro shaqada, iyo iska caabbinta daxalka ayaa aad uga yar kuwa dhoobada birta ah, iyo xoogga aluminiumka aluminiumku aad ayuu uga hooseeyaa kuwa dhoobada birta ah. Sidaa darteed, asal ahaan dhammaan matoorada turbocharged waa blocks bir ah. Waxaa xusid mudan in baloogga dhululubo ee kabka ah uu sidoo kale leeyahay awoodda wax ka beddelka ee matoorka jirka aluminium uusan lahayn.
Taas bedelkeeda, faa'iidada ugu weyn ee dhammaan matoorada aluminiumka ah waa in isla goobta, miisaanka dhammaan matoorada aluminiumku uu ka fudud yahay 20kg marka loo eego matoorada birta ah. Intaa waxaa dheer, saameynta kuleylka kuleylka ee dhammaan aluminiumka aluminiumku aad ayuu uga fiican yahay mashiinka birta, taas oo hagaajin karta waxtarka shaqada ee matoorka iyo caawinta kordhinta nolosha adeegga matoorka.
Waqtigan xaadirka ah, ku dhawaad dhammaan piston-yada matoorada waxay ka samaysan yihiin aluminium aluminium ah. Haddii qalabka gidaarka dhululubada uu sidoo kale yahay dhammaan aluminium, isku-dhafka isku-dhafka u dhexeeya aluminium iyo aluminium ayaa aad u weyn, taas oo saameyn doonta waxqabadka mishiinka. Tani waa sababta xadhkaha birta ah ee birta ah ay had iyo jeer ugu xidhan yihiin jidhka dhululubada ee dhammaan matoorada aluminiumka ah.
Dhab ahaantii, marka la soo koobo, dhammaan mishiinnada aluminiumku waxay leeyihiin sifooyin sifooyin fudud, miisaan fudud, iyo kuleylka wanaagsan. Faa'iidooyinka matoorada birta ah waxay ka muuqdaan caabbinta cadaadiska sare, caabbinta heerkulka sare, caabbinta daxalka, caabbinta qallafsan iyo kharash yar.
