Abstract
Disclosed is an internal combustion engine piston wherein at least one space is formed into which a coolant is installed. In one example, the coolant is first introduced into a coolant container and the coolant container is thereafter inserted into the at least one space in the piston. In one example, the coolant is an alkali metal consisting of sodium.
Claims20
A method for the production of a piston of a combustion engine, having an upper part with a ring zone and a piston skirt adjoining the upper part, the piston upper part and the skirt defining a central region, the method comprising:
- forming at least two elongated spaces obliquely positioned in the piston and aligned in a direction of the central region;
- installing the coolant into each of at least two coolant containers;
- and
- installing each of the at least two coolant containers into one of the at least two spaces in the piston.
A combustion engine piston comprising:
- an upper part having a ring zone;
- a piston skirt connected to the upper part, the piston upper part and skirt defining a central region;
- at least two elongated spaces defined by the piston, each elongated space is obliquely positioned and aligned in a direction of the central region;
- and
- at least two coolant containers operable to first receive and house a coolant, each of the at least two coolant containers and received coolant are respectively positioned in one of the at least two spaces.
A method for producing a combustion engine piston having an upper part including a ring zone, a piston skirt connected to the upper part, the upper part and the skirt defining a central region further defining a central region opening, the method comprising:
- forming a plurality of cooling spaces in the piston, each of the plurality of cooling spaces obliquely positioned and aligned in a direction of the central region opening, each of the plurality of cooling spaces defining an opening;
- installing a coolant in a plurality of coolant containers, the plurality of coolant containers separate and independent of the plurality of cooling spaces;
- sealingly closing the plurality of coolant containers preventing the coolant from exiting the plurality of coolant containers;
- installing the plurality of coolant containers including the coolant in respective of the plurality of cooling spaces;
- and
- preventing the coolant containers from exiting the cooling spaces.
