Abstract: An engine includes at least one cylinder bore having a cylinder wall and a piston positioned within the cylinder bore, and adapted for reciprocal movement therein. At least one piston sleeve is positioned within the cylinder bore, radially between the piston and the cylinder wall. The piston sleeve extends around the piston, and is adapted for reciprocal movement therein. The piston and the piston sleeve are able to move independently of one another. A stop selectively secures the piston sleeve stationary within the cylinder adjacent a top portion of the cylinder. When the stop is de-activated, the piston and the piston sleeve move together within the cylinder, and when the stop is activated, the piston sleeve is secured adjacent the top portion of the cylinder and the piston moves reciprocally within the piston sleeve.
