Abstract
Implementations are disclosed herein that relate to a cylinder occupying structure. An example provides a cylinder system comprising a mechanical cylinder including an internal space in which a fluid is introduced, and a piston configured for reciprocating motion in the internal space, and a cylinder occupying structure including an insertion rod acting as a second piston, wherein the insertion rod is variably inserted into, and retracted from, the internal space of the cylinder in correspondence with the reciprocating motion of the piston and where parts of the insertion rod and the piston may surround the combustion space, and where fluid compression and fluid combustion is conducted within separate spaces.
Claims27
A mechanical engine cylinder system, comprising:
- a cylinder including an internal space;
- an occupying structure;
- and a crankshaft piston;
- wherein the internal space of the cylinder is modified by the occupying structure, having dedicated compression and dedicated combustion spaces;
- wherein the occupying structure provides a surface interface with the dedicated compression space and wherein the occupying structure is responsive to a force application mechanism, and
- wherein the occupying structure completely contains within a cavity, a primary combustion space and a secondary combustion space, during an early stage of a power stroke, and
- wherein, the occupying structure has an edge, that separates the primary and secondary combustion spaces,
- wherein combustion pressure applied to the crankshaft piston is applied to a smaller surface area of the crankshaft piston during an early part of an expansion stroke and to a larger surface area of the crankshaft piston during a later part of an expansion stroke and wherein the force application mechanism is configured to apply a retracting force to the occupying structure during the expansion stroke, and
- wherein combustion pressure applied to occupying structure, applies a net-force to the occupying structure, in the direction of the crankshaft piston, during early part of an expansion stroke, and in the direction of camshaft during a later part of an expansion stroke,
- wherein surfaces of occupying structure, and crankshaft piston, are configured such that, a disengagement happens during an expansion stroke, between the occupying structure and crankshaft piston;
- and
- wherein the motion of occupying structure, during an early part of expansion stroke, creates a suction force of compression fluid into the dedicated compression space.
A method of introducing an occupying structure within a cylinder system,
- the system including a cylinder including an internal space, and the system including a crankshaft piston;
- the method comprising:
- modifying an internal space of a cylinder using the occupying structure such that pressure applied to the crankshaft piston is applied to a smaller surface area of the crankshaft piston during an early part of an expansion stroke and to a larger surface area of the crankshaft piston during a later part of the expansion stroke and wherein the occupying structure is responsive to a force application mechanism;
- and executing a pressure-increasing action within a cavity of the occupying structure to apply pressure to both the occupying structure and the crankshaft piston, such that, the occupying structure accelerates in the direction of the crankshaft during an early stage of power stroke, and in opposite direction during a later stage of power stroke, due to changing the direction of net force applied to occupying structure surfaces;
- wherein the occupying structure includes an elongated cylindrical body to be accommodated within the internal space, the elongated cylindrical body defines a first cavity of primary space and a second cavity of a secondary space;
- wherein the occupying structure competes with fluid in filling the space of displaced volume created by the motion of a crankshaft piston during an expansion stroke and wherein the force application mechanism is configured to apply an advancing force to the occupying structure during the expansion stroke;
- and
- wherein the occupying structure is introduced such that volume filled by the combustion fluid is smaller than the volume displaced by the crankshaft piston due to the occupying structure competing with combustion fluid for space within the cylinder.
