Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mixing water with fuel oil often result in reduced engine output, and existing catalysts may not function efficiently due to particle size limitations, potentially damaging engine components.
Innovation Solution
A water-mixed fuel for diesel engines comprising light oil, 0.2 to 1.0 wt% water, and 0.02 to 0.06 wt% titanium oxide powder with a particle size of 10 µm or less, where the titanium oxide powder acts as a catalyst to enhance combustion efficiency without damaging engine internals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If water is mixed into fuel oil, then combustion efficiency can be improved through catalytic reaction, but engine output is reduced due to water's inability to burn
Solution Approach 1:
The invention optimizes the water content parameter to a specific range (0.2-1.0 wt%) and catalyst concentration (0.02-0.06 wt%) to achieve the best balance between combustion efficiency improvement and engine output maintenance. This parameter optimization resolves the contradiction by finding the precise conditions where catalytic water combustion contributes positively without excessive energy loss.
Solution Approach 2:
The invention introduces titanium oxide powder as an intermediary catalyst that facilitates the combustion of water in the fuel mixture. This mediator enables water to participate in combustion reactions that would otherwise be inefficient, thereby improving overall combustion efficiency while minimizing the negative impact on engine output.
2Reliability
If metal oxide powder with large particle size is used as catalyst, then catalyst stability is improved, but catalytic efficiency decreases due to insufficient contact between water and catalyst
Solution Approach 1:
The invention changes the particle size parameter of the titanium oxide catalyst to a specific range (10 μm or less) that optimizes both catalytic efficiency and stability. This parameter adjustment ensures sufficient surface area for water-catalyst contact while maintaining adequate mechanical stability for engine operation.
3Loss of energy
If metal oxide powder with fine particle size is used as catalyst, then catalytic efficiency is improved through sufficient contact between water and catalyst, but engine components may be damaged due to powder abrasion
Solution Approach 1:
The invention optimizes the particle size parameter to 10 μm or less, which is fine enough to ensure sufficient water-catalyst contact for high catalytic efficiency but not so fine as to cause excessive abrasion damage to engine components. This optimized particle size range resolves the contradiction between catalytic efficiency and engine protection.
Solution Approach 2:
The invention uses a small concentration (0.02-0.06 wt%) of titanium oxide powder that can be consumed or degraded over time without causing significant harm to engine components. The low concentration and optimized particle size ensure that even if some powder causes abrasion, the overall damage is minimized while maintaining catalytic function.
4Loss of energy
If water content in fuel mixture is increased, then combustion efficiency is improved through more water-catalyst reaction, but engine output is reduced due to lower fuel energy density
Solution Approach 1:
The invention optimizes the water content parameter to a specific range (0.2-1.0 wt%) that maximizes the beneficial catalytic combustion effect while minimizing the negative impact on energy density. This parameter optimization resolves the contradiction by finding the precise water content where the net energy benefit is maximized.

AI summary
An object is to provide a water-mixed fuel in which a fuel oil and water are mixed, and a method for producing the same. The present invention is a water-mixed fuel oil which contains a fuel oil, water, and a metal oxide powder, and which is produced by mixing the fuel oil, water, and a metal oxide powder. With the water-mixed fuel oil, the metal oxide powder serves as a catalyst to reduce activation energy of the water, so that the water is eventually burned with the fuel oil, which enables the water to be used as energy.
