ABSTRACT:
A piston for diesel engines is made of a toughness-increasing aluminium alloy containing copper, nickel, silicon, magnesium, iron and manganese. The use of this material, which can conventionally be chill-cast, and by implying special dimensions, provides a piston which, despite its relatively light construction, provides the utmost security against cracking in the stressed regions, e.g. the piston boss or the combustion chamber recess.
