One-stroke internal combustion engine


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.

Method and system for using the by-product of electrolysis


An engine system for generating hydrogen and oxygen, and a method using a by-product of electrolysis, for use in an internal combustion engine to improve efficiency and reduce emissions. The engine system has an electrolysis cell for generating hydrogen and oxygen by electrolysis of an aqueous solution, a battery as a source of power for providing electrical power to the electrolysis cell, and cooling system for maintaining the temperature of the electrolysis cell to reduce problems associated with overheating of the cell during electrolysis.
