Solution Overview
Problem
Existing combustion engines face challenges in optimizing cylinder pressure while minimizing the release of unburned fluids and maintaining energy efficiency, leading to environmental and fuel waste issues.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If stroke volume and/or distance are increased to increase cylinder output, then power output is improved, but cylinder mass increases reducing overall economy
Solution Approach 1:
The patent applies the dynamics principle by making the cylinder occupying structure movable rather than fixed. The insertion rod is advanced into and retracted from the cylinder bore dynamically during different strokes, allowing the system to optimize power output during expansion while minimizing displacement during compression, thereby avoiding the need for permanently enlarged cylinder dimensions.
Solution Approach 2:
The patent implements periodic action by cyclically advancing the insertion rod during compression strokes and retracting it during expansion strokes. This periodic movement allows the cylinder to achieve high power output when needed while maintaining a compact form factor during other phases of the cycle, resolving the contradiction between power and mass.
2Stress or pressure
If throttle method is used to slow down vehicle by releasing non-completely burned fluid, then pressure is released acting on piston, but unburned fluid is wasted and pollution increases
Solution Approach 1:
The patent converts the harmful effect of high cylinder pressure during expansion into a beneficial force by using it to drive the insertion rod forward during compression strokes. The pressure that would normally be wasted is instead harnessed to move the occupying structure, which then aids in compressing the fluid more effectively on the return stroke, turning a potential harm into a useful function.
Solution Approach 2:
The patent recovers energy and fluid that would otherwise be discarded. By using the expansion pressure to advance the insertion rod and by controlling fluid pathways, the system recovers what would normally be wasted unburned fluid and converts expansion pressure into mechanical work for moving the occupying structure.
3Quantity of substance
If direct injection engine methods are used to satisfy environmental requirements, then fluid intake is controlled, but unburned exhaust builds up and may leak backward
Solution Approach 1:
The patent uses dynamic adjustment of the cylinder occupying structure to control fluid pathways. The insertion rod's position is varied during different strokes to dynamically open or close pathways for unburned exhaust, preventing buildup and backward leakage while maintaining control over fluid intake quantities.

AI summary
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.
