整体球墨铸铁活塞正引起四冲程活塞式柴油机制造厂的兴趣。特别在高功率和使用重油运转情况下尤为引人重视。最初,用于内燃机活塞的材料是灰铸铁。后来,铝硅合金显示出许多优点,除个别特殊者外,已普遍用铝硅合金代替铸铁作为所有尺寸的活塞式发动机的活塞材料。作为特例,在通用汽车645系列二冲程柴油机组合活塞上仍使用高强度的可锻铸铁;同样,B＆W、Mirrl- The overall ductile iron piston is attracting the interest of four-stroke piston-type diesel engine manufacturers. Especially in the high-power and heavy oil operation is particularly attractive. Initially, the material for the internal combustion engine piston is gray cast iron. Later, aluminum-silicon alloys showed many advantages. Aluminum-silicon alloys were commonly used instead of cast iron as the piston material for piston engines of all sizes, except for a few special ones. As a special case, high-strength malleable cast iron is still used on GM’s 645 series two-stroke diesel piston; similarly, B & W, Mirrl-
