PCT No. PCT/BR93/00041 Sec. 371 Date Jun. 23, 1995 Sec. 102(e) Date Jun. 23, 1995 PCT Filed Oct. 29, 1993 PCT Pub. No. WO94/15088 PCT Pub. Date Jul. 7, 1995Piston with a reinforcing insert, presenting a top face (11) with a recessed combustion chamber (12) provided with a lateral peripheral wall, defined by the annular insert (20), which presents an internal end face (24) with a radial extension (d1) that is substantially smaller than the radial extension (d2) of the opposite external end face (22) of the annular insert (20). The radial thickness of the insert (20) varies along the profile of its external peripheral face (23), in order to maintain a value necessary to meet the requirements of structural reinforcement of the piston (10), at the region where the insert (20) is applied.
