Abstract
An internal combustion engine may include an engine block, a cylinder defining a combustion chamber, and a piston in the cylinder. The piston may travel in a first stroke from one end to an opposite end of the cylinder, and may be sized relative to the cylinder to enable an expansion stroke portion of the first stroke while the piston travels under gas expansion pressure, and a momentum stroke portion of the first stroke for the remainder of the first stroke following the expansion stroke portion. A piston rod portion may be connected to the piston and extend from a location within the combustion chamber to an area external to the cylinder. A recess in the piston rod portion may form a passageway to continuously communicate gas flow between the combustion chamber and the area external to the cylinder when the piston is in the momentum stroke portion.
