Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid fuels for combustion engines face challenges in achieving efficient fuel consumption, reducing greenhouse gas emissions, and maintaining operational integrity, with many additives either ineffective or causing adverse effects.
Innovation Solution
Incorporating ethyl cellulose powder into liquid fuels, particularly gasoline, enhances combustion efficiency by increasing oxygen content and improving mixture stability, leading to more complete combustion and reduced emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional liquid fuels are used in combustion engines, then the engines can operate and generate power, but fuel efficiency is insufficient and greenhouse gas emissions are high
Solution Approach 1:
The patent changes the chemical composition parameters of the fuel by adding ethyl cellulose powder (0.01-0.5 g per gallon of gasoline), which modifies the combustion characteristics to improve fuel efficiency and reduce emissions. This parameter change approach directly addresses the contradiction by altering the fuel's oxygen content and combustion properties.
Solution Approach 2:
The patent creates a composite fuel system by combining conventional liquid gasoline with ethyl cellulose powder additive. This composite approach integrates the energy-dense gasoline with the oxygen-rich cellulose derivative, achieving both maintained power generation and improved combustion efficiency with reduced harmful emissions.
2Productivity
If fuel additives are introduced to improve combustion efficiency, then fuel efficiency may increase, but the additives can be corrosive or cause adverse effects on engine operation
Solution Approach 1:
The patent employs ethyl cellulose powder as a consumable additive that is mixed with fuel and consumed during combustion. This disposable approach allows the additive to perform its function of improving combustion efficiency without requiring long-term durability or resistance to engine conditions, as it is burned along with the fuel.
Solution Approach 2:
The patent carefully controls the concentration parameter of the ethyl cellulose additive (0.01-0.5 g per gallon) to optimize fuel efficiency improvement while maintaining engine reliability. This parameter optimization ensures the additive provides benefit without causing corrosive effects or operational adverse effects.

AI summary
Disclosed are fuel additives and methods for making and using the same. A fuel additive can ethyl cellulose. A mass of ethyl cellulose in powder form can be mixed with or into a volume of a petrochemical, such as gasoline, in liquid form. The ethyl cellulose powder may at least partially dissolve in the liquid petrochemical. Heat may be applied to improve dissolution of the ethyl cellulose in the liquid petrochemical. The ethyl cellulose/gasoline fuel mixture produced therefrom can be combusted in a combustion engine, such as a small combustion engine. Combustion testing shows that the ethyl cellulose/gasoline fuel mixture exhibits greater than about 150% increase in fuel efficiency relative to gasoline alone. Other additives and stabilizers can be added to stabilize the mixture.
