  • Piston and process for its manufacture
    Patent number: 4291614
    Abstract: An internal combustion engine piston is fitted with bushes between its piston pin and the cross bore in the piston. The diameters of the piston pin and the piston cross bore are dimensioned independently of each other to meet the requirements imposed upon them, which allows the piston pin to be dimensioned only to such size as is required to withstand the bending stress imposed by the connecting rod, thus permitting the size of the piston pin and the reciprocating mass to be reduced in relation to conventional practice.
