摘要： A rotating liner driving mechanism for converting existing engines castings to a rotating liner configuration (RLE) with minor changes to the engine or casting. A pulley is connected to the main accessory belt in the front of the engine and drives a shaft parallel to the crankshaft but external to the engine. Via a 90 degree gearbox, the driving rotation is turned about normal to the crankshaft and block deck face. This shaft drives a driving gear through a gear cover, which then drives one of the liners. Gears in the liner flanges propagate the rotation to all liners. An inline engine needs only one set of pulleys and driving mechanisms, but a V-engine may require two, one for each bank of cylinders. The driving pulley can have mechanisms included so that the gear ratio between crankshaft and rotating liners can be varied during engine operation.

摘要： A hybrid vehicle includes an internal combustion engine, an electric motor/generator and a battery. The drivetrain includes a planetary gear in which the engine is coupled to the sun gear, the motor/generator to the ring gear and the vehicle wheels to the carrier of the planetary. A controller switches the vehicle between electric, assist, charge and regenerative modes of operation and substantially decouples the engine speed from the vehicle speed, enabling the engine to operate at peak efficiency. Additional overdrives are included to enable the engine to operate at optimum speed in the various modes of operation.

摘要： An internal combustion engine is provided including at least one cylinder having a conventional valvetrain. The valvetrain consists of at least one camshaft, at least one intake poppet valve per cylinder activated by the camshaft and at least one exhaust valve per cylinder activated by the camshaft as well. Rotably disposed within the engine block is a rotatable cylinder liner which is supported from the block with at least two journal bearings. A piston is mounted in each liner for reciprocating movement therein. A connecting rod connects each piston to a crankshaft converting the reciprocating motion to crank rotation. The sleeve rotates with the objective of improving the lubrication conditions of the piston rings and piston. The reduction in friction coefficient between the piston rings and liner at certain portions of the cycle will result in significant frictional benefits. The motion of the liner will result in continuous fluid lubrication which results in severe reduction of piston ring and liner wear.

摘要： An improved sealing means for internal combustion engines comprising a combination of a metal primary sealing ring positioned substantially within a groove on the piston, and a compliant secondary sealing ring positioned in the groove behind the primary compression ring so that the compressed combustion gases force the compliant secondary sealing ring to form a seal between the groove and the primary sealing ring. In the preferred embodiment, the gapped ring is non-planar in order to provide effective sealing in a ported fixed-piston, rotating and translating cylinder engine such as the Deckard engine. Alternate embodiments include gapless rings with only a primary compression ring, and gapless rings with a compliant secondary sealing ring. An alternate embodiment is a single piece metal-capped compliant secondary sealing ring.
