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.

1. A reciprocating rotary or straight piston engine for providing an approximately 180° or unidirectional power stroke, the rotary or straight piston respectively comprising
A first piston on a central shaft or tied by external rods to a second piston for reciprocating movement within a cylinder housing, the housing having first, second, third and fourth chambers, each chamber adapted to be in a compressed state when the piston substantially covers the chamber and an expanded state when the piston does not cover the cavity, first and second expanded chambers being dedicated to one of exhaust and compression functions and third and fourth compressed chambers being dedicated to one of intake and ignition in the power stroke, the first piston and second piston moving together, the first and second pistons having a reciprocating motion and the four chambers being dedicated to intake, exhaust, ignition and compression in each of four strokes of a four stroke cycle.
