Umahluko omkhulu phakathi kwentsimbi ephoswe kwibhloko yenjini kunye ne-aluminium alloy bubunzima kunye nomthamo. I-cast iron: Ayimelani namaqondo obushushu aphezulu kwaye ayiguquguquki lula. Emva kokuba injini yentsimbi ephoswe kwi-cast inxityiwe, kulula ukuyilungisa kwaye ixabiso liphantsi. I-aluminium alloy ilula, ishushu ngokukhawuleza, kwaye iinjini ze-aluminium ezikhaphukhaphu zinokunciphisa ubunzima benjini ngokwayo kwaye zifezekise iinjongo zokonga ipetroli. Izinto zeenjini ngoku zahlulwe kakhulu zibe ziintlobo ezimbini. Enye yi-aluminium alloy kwaye enye yi-cast iron. Iingenelo ze-aluminium alloy kukubaibhloko yesilindailula kwaye ivelisa ubushushu obungcono.
Eyona nzuzo inkulu yokusebenza okulula kukuguquguquka ngakumbi. Ngokwethiyori, ukuba ubunzima bulula, ukusetyenziswa kwepetroli kuya kuncitshiswa. Eyona nzuzo kuphela yeebhloko zesinyithi kukuba zinamandla ngakumbi. Ngamanye amazwi, kubanini beemoto abaneemfuno zokusebenza eziphezulu, ibhloko yenjini yesinyithi inokuhlaziywa endaweni ye-aluminium alloy. Ukusebenza kokupholisa kwe-aluminium alloy kulungile kakhulu, okungenakuthelekiswa nanto nge-cast iron. I-cast iron inokumelana okukhulu nokuguquguquka. I-cast iron inomthamo omkhulu wokuthwala umthwalo wobushushu, okungenakuthelekiswa nanto ngezinto ze-aluminium alloy.
Xa kuthelekiswa nentsimbi ephosiweyo, ixabiso eliphezulu lezinto eziluhlaza ze-aluminium alloy yeyona ngxaki inkulu. Ngokuphathelele amandla olwakhiwo, ukumelana nokugqwala kunye nokumelana nokuguguleka, i-aluminium ingaphantsi kunentsimbi ephosiweyo. Iingenelo zezinto zentsimbi ephosiweyo ziindleko eziphantsi, ixabiso eliphantsi, inkqubo yokuvelisa evuthiweyo, amandla esilinda kunye nokumelana nokuguguleka. Kwaye ukumelana nokugqwala kungcono kunokwe-aluminium alloy, kwaye inemveliso engcono yenjini. Iingxaki zezinto zentsimbi ephosiweyo kukuba umgca wemveliso yentsimbi ephosiweyo uhlala kwindawo enkulu, ungcolisa okusingqongileyo, iteknoloji yokucubungula iyinkimbinkimbi, ukusebenza kokusasazwa kobushushu kubi, kwaye ubunzima benjini bunzima kakhulu. Ngenxa yeenzuzo kunye neengxaki zombini Ngokuchaseneyo, ii-cylinders ezenziwe ngentsimbi ephosiweyo zingasetyenziswa ngokubanzi. Uninzi lweenjini zedizili zenziwe ngentsimbi ephosiweyo. Ezinye iinjini zeemoto eziphambili zinokusebenzisa izinto ze-aluminium alloy.
