Gradient Design: Lub piston yas nta ib txheej denser alloy nrog silicon hais, ua zoo li lub tsho khuam insulating.
Microstructure: Cov txheej txheem tshwj xeeb casting tsim ib lub vaj huam sib luag honeycomb, uas ua rau lub thermal expansion coefficient 40% qis dua li txhuas txhuas.
Kev kho deg: Cov yeeb yaj kiab anodized ua zoo li cov txheej txheem ceramic, txo kev sib txhuam thiab tiv thaiv corrosion.
