Abstract: An engine has a crankshaft, rotating about a crankshaft axis of the engine. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of a four stroke cycle during a single rotation of the crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of the same four stroke cycle during the same rotation of the crankshaft. A ratio of cylinder volumes from BDC to TDC for either one of the expansion cylinder and compression cylinder is fixed at substantially 26 to 1 or greater.

Abstract: An internal combustion barrel engine includes an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines a longitudinal axis. A combustion cylinder and a guide cylinder are spaced apart and disposed on a common cylinder axis that is generally parallel to the central axis. The cylinders each have an inner end and an outer end, with the inner ends being closer to each other. The outer end of the combustion cylinder is closed. An intake system is operable to introduce a mixture of air and/or fuel into the combustion cylinder. A track is supported between the inner ends of the cylinders and has an undulating cam surface. The track is moveable such that the portion of the cam surface most directly between the cylinders undulates toward and away from the inner end of the combustion cylinder. A double-ended piston includes a combustion end disposed in the combustion cylinder so as to define a combustion chamber between the combustion end and the closed end of the combustion cylinder. A guide end is disposed in the guide cylinder. A midportion extends between the combustion end and the guide end and is in mechanical communication with the guide surface of the track. A variable compression ratio device is operable to move the track axially towards and away from the inner end of the combustion cylinder so as to adjust the compression ratio. Combustion occurs only in the combustion cylinder and does not occur in the guide cylinder.

Abstract: A method for decelerating an expansion piston of an engine is presented. The engine includes an expansion piston slidably received within an expansion cylinder and operatively connected to a crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of a four stroke cycle during a single rotation of the crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of the same four stroke cycle during the same rotation of the crankshaft. The method includes accelerating the expansion piston during the expansion stroke from the expansion piston's top dead center position, and decelerating the expansion piston during at least a portion of the expansion stroke crank angle interval between 0 degrees and 60 degrees after top dead center.

Abstract: An engine includes a crankshaft having a crank throw, the crankshaft rotating about a crankshaft axis. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of a four stroke cycle during a single rotation of the crankshaft. An expansion piston is slidably received within an expansion cylinder. A connecting rod is pivotally connected to the expansion piston. A mechanical linkage rotationally connects the crank throw to the connecting rod about a connecting rod/crank throw axis such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of the four stroke cycle during the same rotation of the crankshaft. A path is established by the mechanical linkage which the connecting rod/crank throw axis travels around the crankshaft axis. The distance between the connecting rod/crank throw axis and crankshaft axis at any point in the path defines an effective crank throw radius. The path includes a first transition region from a first effective crank throw radius to a second effective crank throw radius through which the connecting rod/crank throw axis passes during at least a portion of a combustion event in the expansion cylinder.
