Internal combustion engine
First Claim
1. 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.

Abstract
An internal combustion engine including at least one engine cylinder, the cylinder includes a cylinder cavity with first and second cylinder heads which are interconnected by a cylinder wall, the cylinder further includes a piston member which is slidably movement within the cylinder cavity and between a first and a second extreme position intermediate between the first and second cylinder heads, the piston member partitions the cavity into a first and a second combustion chambers which are in alternate combustion when in normal engine operation. This engine cylinder configuration substantially increases the usable cylinder volume to enhance efficiency and reduces the weight to power ratio.

- 1. 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.
- 9. 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, said cylinder further including a piston member which is slidably moveable within said cylinder cavity between first and 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, said diaphram member including a spacer separating a cylinder head and the corresponding piston surface of a combustion chamber, thereby defining the minimum volume of said combustion chamber, said diaphram member including a base and a wall surrounding said base, said wall axially extending away from said base and said cylinder head adjacent said base such that the axial extension of said wall defines the minimum axial clearance of said combustion chamber containing said diaphram member.
- 12. 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, said cylinder further including a piston member which is slidably moveable within said cylinder cavity between first and 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 including a bifurcated pair of legs protruding out of said cylinder, said bifurcated legs being connected with a rotary power transmission member which converts the translational movements of said bifurcated legs into rotary movements of said rotary member.

15. An internal combustion engine including at least an engine cylinder, said engine cylinder including a hollow cylinder room enclosed by a cylinder wall and a first and a second cylinder heads at the ends of said cylinder room,
said engine cylinder further including a piston having a first and a second piston surfaces, said piston being disposed within said cylinder room and partitioning said cylinder room into a first and a second combustion chambers, wherein said first combustion chamber is formed by co-operation of said first piston surface and said first cylinder head and said second combustion chamber is formed by co-operation of said second piston surface and said second cylinder head, said piston being movable between a first and a second piston positions between said cylinder heads and being connected with a power transmission link which extends from one of said piston surfaces towards the corresponding opposing cylinder head and exits from said cylinder room at said corresponding opposing cylinder head to extend outside said cylinder room, said first and second piston positions corresponding respectively to said first and second combustion chambers at their minimum chamber volumes, such that, during engine operations, a complete cycle of reciprocating movements of said piston from one starting position back to that starting position corresponds to a complete engine combustion cycle in both said first and second combustion chambers.
