Izici zenqubo：in-line, four-cylinder, enezikhala zomjovo ezomile. Ubukhulu be-wal ye-core ye-jacket yamanzi ye-cylinder block buncane (4mm endaweni ethile), futhi i-sand core kulula ukuyiguqula, okwenza kube lula ukuholela ekungazinzi kobukhulu be-wal ye-cylinder hole. Inqubo yokuphonsa, i-water jacket core ihlale ihlanganiswe ne-parallel core heads phezulu kwe-cylinder ukuze kuqinise ukujula nokuvikela i-sand core ekuguqulweni. Ngaphezu kwalokho, inqubo yokuhlanganisa i-core eyodwa iyasetshenziswa, okungukuthi, i-water jacket core ne-tappet core zihlanganiswa ku-main core assembly ngaphambi kokufaka i-dip-coating, kulandelwa i-dip-coating eyodwa. Kuwo wonke umjikelezo wokukhiqiza, i-robot isetshenziswa ekwenzeni i-core, ekuhlanganiseni i-core, ekufakeni i-dip-coating nasekufakeni i-core, ukuze kuqinisekiswe ukunemba kwesikhala se-sand core, ukuze kuqinisekiswe ubukhulu be-wal ye-cylinder hole nokuthuthukisa ukunemba kwezilinganiso zokuphonsa.
