Abstract:
An internal combustion engine including at least one engine cylinder, said cylinder including a cylinder cavity with first and second cylinder heads which are interconnected by a cylinder wall, a piston member which is slidably moveable within said cylinder cavity between a first and a second extreme positions which are intermediate said first and second cylinder heads, such that said piston member partitions said cavity into a first combustion chamber and a second combustion chamber which alternatively combust when said engine is in normal operation, said piston member being connected with a power transmission member extending from said piston member to outside said cylinder cavity, and a slidable diaphram member disposed in each said combustion chamber and partitioning said combustion chamber into a first compartment with one end being a cylinder head and a second compartment with one end being said piston, said first and second compartments being generally not mutually communicable except at a specific position of said diaphragm member at which position combustible gas in said first compartment will be transferred to said second compartment during normal engine operations.
