Abstract
A piston ( ) particularly suited for heavy duty diesel engine applications includes upper and lower crown sections ( ) joined by a friction weld ( ) to define an annular ring belt ( ) formed with ring groves ( ) and having a lower end ( ) and an internal piston cooling chamber ( ). A pair of pin bosses ( ) depend from the ring belt ( ) and are formed as one piece with the lower crown section ( ). A skirt ( ) is also formed as one piece with the pin bosses ( ) and has an upper end ( ) that is spaced from the lower end ( ) of the ring belt ( ) to define a space ( ) therebetween which effectively uncouples the skirt ( ) from the ring belt ( ).
