Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fuel compositions for combustion engines inadequately oxidize fuels, leading to the production of toxic emissions such as carbon monoxide (CO) and unburnt hydrocarbons (HC), which pose health risks and environmental hazards, despite advancements in engine technology and catalysts.
Innovation Solution
A novel fuel additive comprising isopropanol (60-70 vol.-%), diesel or linseed oil (15-25 vol.-%), gasoline (10-20 vol.-%), and water (1-5 vol.-%), which, when mixed homogeneously, reduces toxic emissions when burned in combustion engines, particularly CO and HC, and can include urea for enhanced nitrogen oxide conversion.

Engineering Contradiction Analysis
1Productivity
If conventional diesel or gasoline is burnt in combustion engines, then energy is produced to propel vehicles, but toxic emissions such as carbon monoxide (CO) and unburnt hydrocarbons (HC) are generated due to inadequate oxidation
Solution Approach 1:
The patent applies composite materials by creating a fuel mixture composed of multiple components (isopropanol, diesel, gasoline, and water) in specific proportions. This composite fuel formulation enables more complete combustion compared to conventional single-component fuels, thereby reducing toxic emissions while maintaining energy production capability
Solution Approach 2:
The patent changes the chemical composition parameters of the fuel by incorporating isopropanol (60-70 vol.-%) and water (1-5 vol.-%) in specific concentrations. These parameter changes modify the combustion characteristics to achieve more complete oxidation, reducing CO and HC emissions while preserving sufficient energy output for vehicle propulsion
2Object-generated harmful factors
If catalysts are built in vehicles to reduce contaminants, then toxic emissions are reduced, but device complexity and cost increase
Solution Approach 1:
The patent extracts the emission reduction function from the catalyst system and transfers it to the fuel composition itself. By formulating a combustion-optimized fuel mixture, the invention achieves emission reduction through chemical composition rather than requiring additional catalytic devices, thereby simplifying the overall vehicle system
Solution Approach 2:
The fuel composition itself performs the emission reduction function through its optimized chemical composition and combustion characteristics. The fuel acts as its own treatment mechanism, eliminating the need for separate catalyst systems and reducing device complexity while maintaining effective reduction of toxic emissions
