Abstract: Engines and methods execute a high efficiency hybrid cycle, which is implemented in a volume within an engine. The cycle includes isochoric heat addition and over-expansion of the volume within the engine, wherein the volume is reduced in a compression portion of the cycle from a first quantity to a second quantity, the volume is held substantially constant at the second quantity during a heat addition portion of the cycle, and the volume is increased in an expansion portion of the cycle to a third quantity, the third quantity being larger than the first quantity.

Abstract: A seal assembly includes first and second seal elements configured to lie adjacent to one another with a lower portion of each one disposed in a groove and an upper portion of each one projecting above the groove. The groove has a length disposed transverse to the direction of relative motion of a housing and a moving member and is located in the housing. The seal elements are further configured so that a contact surface of the upper portion of each seal element abuts the moving member and configured to allow independent movement of each seal element relative to each other in a direction transverse to the groove length. The seal elements are shaped to define a lubrication channel therebetween that is configured to allow the passage of a lubricant therein so as to lubricate motion of the seal elements relative to each other and relative to the moving member.

Abstract: An improved internal combustion engine of the four-stroke variable volume type operates by refraining from introducing substantial fuel into the working medium during the compression stroke until substantially maximum pressure of the working medium has been reached and utilizing at least one of the following processes: (a) causing combustion of fuel under substantially constant volume conditions; and (b) causing the power stroke to provide a larger volume to combustion products than the compression stroke provides to the working medium. Related methods are also provided.
