Claims17
A method of making a cylinder, comprising:
- forming a cylinder comprising at least one combustion chamber having a paraboloidal cavity and a squish area having a non-zero squish angle disposed at or around a base of the at least one combustion chamber;
- adapting the cylinder to include a sparkplug port, whereby an electrode of a sparkplug may be positioned at or near a focal point of the paraboloidal cavity via the sparkplug port;
- providing a piston with a volumetrically-enhanced portion, wherein the volumetrically-enhanced portion is adapted to extend into the paraboloidal cavity when the piston is at top dead center;
- and
- placing the piston within the cylinder;
- wherein the cylinder has a squish ratio greater than or equal to 0.5.
