Ingqikithi yokuqukethwe: I-lightweight yenjini ayiyona nje kuphela indlela ebalulekile yokonga amandla emoto kanye nokunciphisa ukungcola, kodwa futhi enye yezinjongo ezilandelwa ukuthuthukiswa kwezimoto.I-lightweight yenjini ngokuyinhloko iyisilinda esiyisilinda.Kunezindlela ezimbili eziyinhloko zokukhanyisa ibhulokhi yesilinda: enye iwukukhetha ingxubevange ye-aluminium enomthamo ophansi wezinto ezibonakalayo, kanti enye iwukunciphisa ukujiya kodonga.Ngokuvamile impahla iyi-vermicular cast iron noma i-ductile iron.Kodwa-ke, insimbi empunga isasetshenziswa kabanzi kusukela kusilinda esisodwa kuya kumasilinda aqondile angama-2-6, kanye namasilinda e-V6 ne-V8;Ngisho ne-cylinder block yenjini enkulu ye-marine diesel yenziwe nge-grey cast iron.Lokhu kungenxa yokuthi i-grey cast iron cylinder block ine: izindleko eziphansi zokukhiqiza uma ziqhathaniswa ne-cast cast aluminium alloy cylinder block;Ukumelana nokuzamazama okuhle kakhulu, umphumela wawo we-anestic (ukungqubuzana kwangaphakathi) mkhulu kakhulu kunowe-aluminium alloy, mkhulu nakakhulu kunalowo wensimbi ne-ductile iron.I-Flake graphite cast iron ine-conductivity enhle yokushisa kanye nokuzwela kwenotshi encane.Ama-cylinder blocks we-hm479q, M12, jl1.8t nezinye izinjini zezimoto ezikhiqizwe inkampani yethu enziwe nge-HT250 ne-HT300.Ama-cylinder block castings ahlangabezana nezinga lekhwalithi yomkhiqizo atholwe ngokusakazwa okuqondile kanye nenqubo yomjovo ophansi, ingxubevange ephansi ye-CE kanye ne-Sr Si inoculant.
