Abstract

See full text

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.
