Abstract:
A piston for an internal combustion engine including a piston body (20). The piston body (20) defines a first cooling chamber (46) that is sealed closed and contains a first cooling medium (48) other than air. During operation of the piston, the first cooling medium (48) extracts heat from the surrounding regions of the piston body (20) to cool the piston body (20). The piston body (20) also defines a second cooling chamber (50) adjacent to the first cooling chamber (46). A cooling oil (51) is projected into the second cooling chamber (50) and against the portion of the piston body (20) separating the first and second cooling chambers (46, 50) to extract heat from the first cooling medium (48). The cooling oil (51) is redirected within the second cooling chamber (50) to extract additional heat from the first cooling medium (48) or directly from the piston body (20).
