One-stroke internal combustion engines may comprise reciprocating pistons which are either straight or rotary. Three principles are required to make one-stroke engines work: create four dedicated chambers, assign the chambers with coordinated functions, and make pistons move in unison. The functions will be assigned only to a single stroke but an Otto cycle produces a repeating four stroke cycle. Since four functions are performed simultaneously during one stroke, every stroke becomes a power stroke. In reality. 1-stroke engines are physically rearranged 4-stroke engines. Both straight and rotary 1-stroke engines can be modified to comprise opposed piston opposed cylinder (OPOC) engines. The reciprocating piston output of 1-stroke pistons may be converted to continuously rotating output by using crankshafts with split bushings or newly developed Crankgears with conventional bearings. A 1-stroke engine may require only one crankshaft and thus may reduce the number of parts and increase the specific power ratio. Outputs of two 1-stroke engines may be combined using a spur/helical gear assembly to increase power output.
A reciprocating rotary engine for providing a greater than 180° or unidirectional power stroke, the rotary piston engine respectively comprising
An opposed piston, opposed cylinder straight-line internal combustion engine having first and second double-headed pistons aligned on a central shaft for straight-line reciprocating motion in a piston housing also containing a third and fifth single-headed piston and a fourth double headed piston connected to a first rod external to the piston housing and the first, second, third, fourth and filth pistons forming first, second, third and fourth dedicated chambers within the piston housing, the first external rod for connection to a crankshaft and the central shaft for connection to the crankshaft producing reciprocating movement of the crankshaft such that the crankshaft rotates in one direction.
A rotary opposed piston, opposed, cylinder one-stroke Internal combustion engine having a one hundred eighty degree power stroke per piston wherein a piston of the engine comprises a first opposed pair of pistons moving in opposite clockwise and counterclockwise directions within an internal housing containing a second opposed pair of pistons moving the opposite counter-clockwise and clockwise directions, the internal housing having an external housing for containing the internal housing, the internal housing forming first, second, third and fourth dedicated chambers.
A rotary one-stroke internal combustion engine having a greater than 180° power stroke, the engine comprising a cylindrical housing having a center plate separating the housing into first and second compartments bounded by first and second end plates, the first compartment including the first end plate and comprising a first piston for greater than 180° movement within the first compartment bounded by a first partition, the first piston mounted on a central shaft,
