Okwangoku, kukho iintlobo ezimbini eziphambili zeenjini zeemoto: iinjini zentsimbi kunye neenjini ze-aluminiyam. Ke yeyiphi kwezi njini zimbini zempahla eyona ilungileyo ukuzisebenzisa? Yintoni umahluko phakathi kweenjini ezimbini? Enyanisweni, phantse zonke izixhobo zentloko ye-injini ye-cylinder zenziwe nge-aluminiyam, kuba iintloko ze-aluminium ze-cylinder zineyona ndlela ingcono yokuchitha ubushushu. Intloko ye-cylinder ye-injini yentsimbi eneneni yi-aluminium alloy, kodwa ibhloko ye-cylinder yintsimbi.
Xa kuthelekiswa ne-injini ye-aluminiyam yonke, ibhloko ye-cylinder ye-injini ye-cast-iron inomthamo oqinileyo womthwalo we-thermal, ovumela ngakumbi ukwandisa amandla e-injini. Ngokomzekelo, phantsi kwempembelelo ye-turbocharging, i-1.5L yokufuduka kwe-injini ye-iron inokufikelela ngokwenene kwi-2.0L imfuneko yamandla okufuduswa; ngelixa i-injini ye-aluminiyam yonke ayinakuhlangabezana nemfuneko enjalo. Okwangoku, kuphela iimoto ezimbalwa eziphezulu zisebenzisa i-injini ye-aluminium yonke.
Ukongeza, zonke ii-injini ze-aluminiyam ziqhelene nokusabela kweekhemikhali ngamanzi ngexesha lomsebenzi, kwaye ukuxhathisa kwazo kuncinci kakhulu kuneesilinda zentsimbi, kwaye amandla eesilinda ze-aluminium angaphantsi kakhulu kuneesilinda zentsimbi. Ke ngoko, zonke ii-injini ze-turbocharged zineebhloko zentsimbi. Kuyafaneleka ukukhankanya ukuba ibhloko ye-cylinder yentsimbi etyhidiweyo inamandla okuguqula ukuba i-injini yomzimba we-aluminium ayinayo.
Ngokwahlukileyo koko, eyona nzuzo inkulu kuzo zonke ii-injini ze-aluminiyam kukuba kwindawo enye, ubunzima beenjini ze-aluminiyam bumalunga ne-20kg bukhaphukhaphu kunobo beenjini zentsimbi. Ukongezelela, umphumo wokutshatyalaliswa kobushushu be-injini ye-aluminium yonke ingcono kakhulu kune-injini ye-iron-iron, enokuphucula ukusebenza kakuhle kwe-injini kunye nokunceda ukwandisa ubomi benkonzo ye-injini.
Okwangoku, phantse zonke iipistons ze-injini zenziwe nge-aluminium alloy. Ukuba i-cylinder wall material nayo yonke i-aluminium, i-coefficient of friction phakathi kwe-aluminium kunye ne-aluminium inkulu kakhulu, eya kuchaphazela ukusebenza kwe-injini. Kungenxa yoko le nto ii-injini zentsimbi zihlala zifakwe kwi-cylinder body of all-aluminium engines.
Enyanisweni, isishwankathelo, i-injini ye-aluminiyam yonke ineempawu zokucutshungulwa lula, ubunzima obulula, kunye nokuchithwa kakuhle kobushushu. Iingenelo zeenjini zentsimbi zibonakaliswa kukumelana noxinzelelo oluphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-corrosion, ukumelana ne-deformation kunye neendleko eziphantsi.
