Example

[0033] As illustrated in FIGS. 1-3, the engine has a pair of rotors 21, 22 with pistons 23, 24 which are spaced circumferentially of the rotors and disposed within a toroidal chamber or cylinder 26. The pistons on the two rotors are interposed between each other around the cylinder, with chambers 27 being formed between successive pistons on the two rotors. As discussed more fully hereinafter, the two rotors turn alternately and in stepwise fashion, with the pistons on one rotor remaining substantially stationary while the pistons on the other advance. Chambers 27 vary in volume as the pistons advance, with the chambers on the back sides of the moving pistons increasing in volume and the chambers on the front sides decreasing. With the alternating movement of the rotors, chambers which increase in volume during one step will decrease during the next.

[0034] Fuel is introduced into the chambers through intake ports 28, and spent gases are expelled through exhaust ports 29. The ports ...

Abstract

Internal combustion engine and method in which pistons on different rotors move relative to each other to form chambers of variable volume in a toroidal cylinder. The pistons move in stepwise fashion, with the pistons on one rotor travelling a predetermined distance while the pistons on the other rotor remain substantially stationary. Fuel is drawn into a chamber as one of the pistons defining the chamber moves away from the other, and then compressed as the second piston moves toward the first. Combustion of the fuel drives the first piston away from the second, and the spent gases are then expelled from the chamber by the second piston moving again toward the first. An output shaft is connected to the rotors in such manner that the shaft rotates continuously while the rotors and pistons move in their stepwise fashion.

Description

CROSS-REFERENCE TO APPLICATIONS [0001] This is a continuation of Ser. No. 10 / 852,915, filed May 24, 2006, which was a division of Ser. No. 10 / 108,186, filed Mar. 26, 2002, now U.S. Pat. No. 6,739,307.BACKGROUND OF THE INVENTION [0002] 1. Field of Invention [0003] This invention pertains generally to machines such as engines, pumps, and the like and, more particularly, to a positive displacement internal combustion engine and method. [0004] 2. Related Art [0005] For more than a century, internal combustion engines have been relied upon a principal source of power in a variety of applications. Of those engines, the most widely used are the reciprocating piston engines which are found in automobiles and other forms of transportation, as well as in a variety of industrial and consumer applications. Such engines can be built in a variety of sizes, depending upon the power requirements of a particular application, ranging from a single cylinder up to 32 cylinders or more. Other types of i...
