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.
Claims17
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 such that 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 the expansion stroke;
- wherein the occupying structure is a movable structure relative to the cylinder, and wherein movement of the occupying structure is controlled by one or more forces applied by a force application mechanism;
- and
- wherein the force application mechanism is responsive to throttle position by way of throttle position sensors such that one or more forces applied to the occupying structure are dependent on throttle position.

A mechanical engine cylinder method using a system, the system comprising:
- a cylinder including an internal space in which fluid is introduced, and a crankshaft piston configured for reciprocating motion in the internal space;
- an occupying structure;
- and
- wherein the internal space of the cylinder is modified by the occupying structure by insertion of the occupying structure to displace a portion of the internal space, such that the occupying structure reduces a fluid intake, and such that 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 the expansion stroke;
- wherein the system is configured such that combustion occurs within a cavity of the occupying structure to apply combustion pressure to both the occupying structure and the crankshaft piston;
- wherein the occupying structure is a movable structure relative to the cylinder, and wherein movement of the occupying structure controlled by one or more forces applied by a force application mechanism;
- wherein the force application mechanism is responsive to throttle position by way of throttle position sensors such that one or more forces applied to the occupying structure are dependent on throttle position;
- wherein the system is configured to partially execute a compression stroke during the expansion stroke by applying a force to the occupying structure via the force application mechanism;
- wherein the system is configured to have an initial movement of the occupying structure drag combustion fluids and forces in the direction of the camshaft piston to absorb part of the engine vibration forces;
- wherein the occupying structure changes direction during the expansion stroke;
- wherein the system is configured to perform intake, compression, expansion, and exhaust functions within two strokes per combustion;
- the method comprising:
- actuating the crankshaft piston during an expansion stroke in a first direction;
- during the expansion stroke, advancing the cylinder occupying structure into the internal space of the cylinder in correspondence with motion of the crankshaft piston;
- actuating the crankshaft piston during a compression stroke in a second direction substantially opposite to the first direction;
- and
- during the compression stroke, retracting the occupying structure from the internal space of the cylinder in correspondence with the motion of the crankshaft piston;
