One-stroke internal combustion engine

摘要

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.

主权项

1. An internal combustion engine having four power strokes of a four stroke Otto cycle, the internal combustion engine comprising:
a piston assembly of four single-headed pistons for driving a crankshaft, each single-headed piston mounted in a respective cylindrical housing having an end plate, each end plate and each corresponding single-headed piston having a central shaft mounted for reciprocating motion with the other three single-headed pistons to drive the crankshaft, the crankshaft being coupled to an output shaft for rotational movement through one hundred eighty degrees with each power stroke of the four piston assembly, the four pistons being numbered one, two, four and three in order along the crankshaft, the first and third single-headed pistons one and three being located opposite to the second and fourth single-headed pistons two and four, the first and third single-headed pistons one and three being mounted on an opposite side of the crankshaft and the second and fourth single-headed pistons two and four being mounted adjacent to one another and on an opposite side of the crankshaft from the first and third single-headed pistons one and three, the cylindrical housings defining respective, alternatively expandable and compressible chambers between the end plates of the cylindrical housings and the respective first through fourth pistons of the piston assembly such that when first and third chambers of the housings of the first and third pistons are expanded, the second and fourth chambers of the housings of the second and fourth pistons are compressed; and the first, second, third and fourth chambers respectively being sequentially ignited in four power strokes of a repeating Otto cycle.
