Claims15
An apparatus comprising:
- a cylinder having at least one combustion chamber and a squish area having a non-zero squish angle disposed at or around a base of the at least one combustion chamber;
- wherein the at least one combustion chamber comprises a paraboloidal cavity;
- wherein the cylinder has a squish ratio greater than or equal to 0.5;
- and
- wherein the cylinder is adapted to position an electrode of a sparkplug at a focal point of the paraboloidal cavity.

- a cylinder having at least one combustion chamber and a squish area having a non-zero squish angle disposed at or around a base of the at least one combustion chamber;
- wherein the at least one combustion chamber comprises a paraboloidal cavity;
- wherein the cylinder is adapted to position an electrode of a sparkplug at or near a focal point of the paraboloidal cavity;
- at least one piston having a piston top comprising a volumetrically-enhanced portion that extends into the paraboloidal cavity when the piston is at top dead center;
- wherein the cylinder includes a cylinder body and a cylinder head;
- wherein the cylinder head comprises the at least one combustion chamber and a sparkplug port;
- wherein the sparkplug port is offset from the centerline of the cylinder;
- and wherein an axis of symmetry of the paraboloidal cavity coincides with a centerline of the cylinder or a center of the piston top.
