Abstract (en)
[origin: WO2008000347A2] The invention relates to a steel piston for internal combustion engines, comprising at least one piston upper part (12) provided with a combustion cavity (11) and an annular wall (5), and a piston lower part (13) provided with a connecting rod bearing (8). The steel piston is cast as a single component from a reduced-density steel alloy or a special steel alloy in the same material by means of a low-pressure casting method.
