Piston having a barrel of forged steel and a cooling channel |
摘要 |
A piston with a cooling channel having a basic piston barrel made from forged steel and a box-shaped shaft, bosses and boss supports and connecting walls between the boss supports as well as a combustion trough. The piston increases the rigidity of the ring part. To accomplish this, the piston has a wall extending all around above the boss bores. A structural component is welded in between the wall and the piston head and limits the cooling channel. This design increases the rigidity of the ring part in pistons.
