Abstract
A reciprocating piston engine wherein the movement of a piston within the combustion chamber creates vortices in the fluid within the chamber and wherein the orientation of the vortices is more normal to the axis of movement of the piston than parallel to the axis of movement of the piston. The vortices may be created by a device for attachment to the crown of a piston or by the configuration of the crown of the piston. The vortices may be created by a plurality of vanes extending outwardly from the center of the piston to the periphery thereof.
Claims36
An internal combustion engine having a piston reciprocatingly slidable within a combustion chamber along the sliding axis thereof (a) to compress for combustion a fluid mixture including oxygen and a combustible fuel, and (b) to provide driving power in response to the combustion of the fluid mixture within the chamber,
- wherein the surface of the piston in contact with the fluid mixture causes vortices in a substantial portion of the fluid mixture as the piston moves within the chamber,
- and wherein the orientation of one or more of the vortices created within the fluid mixture relative to the direction of movement of the piston is more lateral than axial.
In an internal combustion engine having a piston reciprocatingly slidable within a combustion chamber along the sliding axis thereof (a) to compress for combustion a fluid mixture including oxygen and a combustible fuel, and (b) to provide driving power in response to the combustion of the fluid mixture within the chamber,
- the improvement wherein the surface of the piston in contact with the fluid mixture includes a plurality of vanes extending from the piston generally axially of the chamber and extending generally from the center of the piston outwardly toward the periphery thereof,
- each of said vanes having two walls extending generally axially from the piston to a connecting surface at the distal end of the vanes, and
- the slope relative to the sliding axis of the piston of one of said walls being greater than the slope of the other of said walls.
A device for attachment to the crown of a piston reciprocatingly carried in the combustion chamber of a reciprocating piston engine, said device comprising an aerodynamic structure for causing vortices in a substantial portion of the fluid contained in said chamber during reciprocation of the piston, the orientation of the vortices being more orthogonal to the axis of piston movement than parallel to the axis of piston movement.
A device for attachment to the crown of a piston in a reciprocating piston engine, said device comprising a central portion and a plurality of vanes extending outwardly from said central portion toward the periphery of the piston crown, each of said vanes comprising two walls extending from the crown in the direction of movement of the piston and a connecting surface connecting said walls at the distal ends thereof the slope relative to the direction of movement of the piston of one of said walls being greater than the slope of the other of said walls.
A method of generating combustion enhancing turbulence in the fluid within a combustion chamber of a reciprocating piston engine, said method comprising the step of creating vortices in a substantial portion of the fluid as the piston reciprocates through the chamber having an orientation that is more orthogonal than parallel to the reciprocating axis of the piston.
A method of generating combustion enhancing turbulence in the fuel mixture in the combustion chamber of a reciprocating piston internal combustion engine including the step of creating flow in the fuel air mixture by the movement of the piston, wherein a substantial portion of the flow comprises one or more vortices having an orientation more normal to the direction of movement of the piston than parallel the direction of movement of the piston.
