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.
Claims21
(canceled)
The piston of claim 11, further comprising a closure element positioned over an opening defined by the space, the closure means operable to close the space opening after the insertion of the coolant container in the space.
The piston of claim 11, wherein after insertion into the space, the coolant container is fixed in its position in the space.
The piston claim 11, wherein the coolant container further comprises an elongate and cylindrical body.
The piston of claim 11, wherein the coolant container is cast into the piston.
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, wherein at least one space is formed in the piston, into which at least one space a coolant is introduced, the method comprising:
- installing the coolant into a coolant container;
- and
- installing the coolant container into the at least one space in the piston.
A combustion engine piston comprising:
- an upper part having a ring zone;
- a piston skirt connected to the upper part;
- a space defined by the piston;
- and
- a coolant container operable to first receive and house a coolant, the coolant container and received coolant positioned in the space.
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 method comprising:
- forming a plurality of cooling spaces in the piston, 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.
