Oxygen-Enriched Combustion for Internal Combustion Engine Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion engines face inefficiencies and emissions challenges when operating with traditional fuels, and there is a need for alternative fuels and oxygen-enriched combustion methods to improve performance and reduce environmental impact.
Innovation Solution
The method involves providing an oxygen-containing gas with greater than 22 volume percent oxygen and combining it with alternative fuels such as methanol, ethanol, or butanol to form a combustible mixture, which is then used to operate an internal combustion engine. This can include enriching ambient air with oxygen or using stored oxygen-enriched gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fuels are used in internal combustion engines, then the engine can operate with conventional fuel systems, but efficiency and emissions performance are insufficient
Solution Approach 1:
The patent applies oxygen-enriched air (greater than 22 volume percent oxygen) to accelerate combustion of alternative fuels in the internal combustion engine. This strong oxidant approach improves combustion efficiency and reduces harmful emissions by ensuring more complete oxidation of the fuel, directly addressing the contradiction between engine efficiency and emissions performance
Solution Approach 2:
The patent changes the oxygen concentration parameter in the combustion air from conventional levels (approximately 21% oxygen) to enriched levels (greater than 22 volume percent oxygen). This parameter change enables more efficient combustion of alternative fuels while reducing emissions, resolving the technical contradiction
2Object-generated harmful factors
If alternative fuels are used to reduce emissions, then environmental impact is reduced, but combustion efficiency may decrease
Solution Approach 1:
By providing oxygen-enriched air to the engine, the patent ensures that alternative fuels burn more completely and efficiently. The increased oxygen availability compensates for any combustion inefficiencies inherent in alternative fuels, maintaining productivity while achieving reduced emissions
3Productivity
If oxygen-enriched air is provided to improve combustion, then combustion efficiency increases, but system complexity increases
Solution Approach 1:
The patent introduces an oxygen enrichment system as an intermediary component between the ambient air and the engine combustion chamber. This mediator (oxygen-enriched air) enables improved combustion efficiency while the system design integrates this complexity in a manageable way through controlled oxygen addition
