Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reciprocating engines rely on combustion for drive energy, producing exhaust gases and requiring complex valve operations that can lead to contamination and maintenance challenges.
Innovation Solution
A reciprocating piston engine with double piston cylinders and dual circuit arrangement, utilizing the pressure of a flowing medium to drive the engine without combustion, with synchronized inlet and outlet valves to manage work volume changes efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If combustion is used to generate drive energy, then power output is improved, but exhaust gases are produced and maintenance complexity increases
Solution Approach 1:
The invention extracts and eliminates the combustion process from the engine system, replacing it with a mechanical compression-expansion cycle using inert gas. This removes the source of exhaust gases while maintaining the fundamental reciprocating motion that generates power.
Solution Approach 2:
The patent introduces an inert gas (such as nitrogen or carbon dioxide) into the combustion chamber, replacing the combustible air-fuel mixture. This inert atmosphere prevents combustion and exhaust gas formation while still allowing the gas to be compressed and expanded to drive the piston.
2Power
If combustion is used to generate drive energy, then power output is improved, but device complexity and maintenance needs increase
Solution Approach 1:
The invention removes the combustion process and associated complex valve timing mechanisms from the engine. By using simple inlet and outlet valves that operate based on piston position rather than complex camshaft timing, the device complexity is reduced while maintaining power generation capability.
3Volume of moving object
If inlet valve is not opened in each work phase, then work volume increases, but medium flow and drive energy are reduced
Solution Approach 1:
The invention dynamically adjusts the inlet valve opening based on piston position and pressure differential. The inlet valve opens when the piston moves downward creating a pressure differential, allowing medium to enter the work volume, and closes when the piston moves upward. This dynamic operation optimizes both work volume and drive energy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The engine operates efficiently using inert media, reducing maintenance needs and eliminating exhaust gases, while maintaining performance without combustion.
Implementation Method 1
The drive energy of the operating engine results from the pressure with which the medium flows through the open inlet valve or open inlet valves that are allocated to the open inlet valve

AI summary
The present invention relates to a working engine that comprises a working volume or plurality of working volumes. The working volume(s) are each assigned one or more inlet valves and one or more outlet valves. The inlet valve(s) are connected to a supply line arrangement that supplies a medium. The inlet valve(s) are arranged so that when an inlet valve is open, the medium is supplied to the working volume assigned to the inlet valve. The outlet valve(s) are connected to a discharge line arrangement. In the working phase of increasing the working volume(s), the inlet valve(s) associated with the working volume(s) are open and the outlet valve(s) associated with the working volume(s) are closed. In the working phase of reducing the working volume(s), the outlet valve(s) associated with the working volume(s) are open and the inlet valve(s) associated with the working volume(s) are closed.
