ABSTRACT:
A piston for an internal combustion engine including a crown, a skirt and bosses. The skirt has a circumferentially extending faucet rib in a lower portion of the skirt and reinforcing ribs which extend in a thrust and thrust-opposing direction of the piston from the bosses straight to the faucet rib. Reinforcing ribs increase the rigidity of piston in the thrust and thrust-opposing direction and suppress parmanent deformation of the skirt in the thrust and thrust-opposing direction, resulting in decreasing slapping sounds in a piston and cylinder structure without sticking of a piston with a cylinder bore.
