Solution Overview

Problem

Existing gasoline additives face issues with stability and cost due to high water content requirements for improved combustion efficiency and emission reduction, leading to separation, corrosion, and blockages in fuel systems.

Innovation Solution

A microemulsion of modified bio-carbon, an anionic surfactant, water, and a modified vegetable oil, with a low water incorporation ratio, is used to create a stable and efficient gasoline efficacy promoter (GEP) that enhances combustion and reduces NOx emissions by micro-dissociation and ultrasonication processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If high water content is incorporated into fuel microemulsion to improve combustion efficiency and reduce emissions, then combustion efficiency increases and NOx emissions decrease, but microemulsion stability deteriorates causing separation and fuel system blockages

Engineering Contradiction:
Improvecombustion efficiencyVSAvoidmicroemulsion stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent changes the physical-chemical parameters of the microemulsion by using modified bio-carbon with specific surface area (500-2000 m²/g) and pore structure, combined with specific surfactant concentrations (1-10% by weight) and controlled water content (5-50% by weight). This parameter optimization allows achieving both high combustion efficiency and microemulsion stability without separation or blockages.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite microemulsion system combining modified bio-carbon, surfactants, water, and vegetable oil in specific proportions. This composite structure leverages the high surface area and porous nature of modified bio-carbon to stabilize water droplets while maintaining combustion performance, resolving the contradiction between efficiency and stability.

Inventive Principle:
Principle #40Composite materials

2Object-generated harmful factors

If high water content is used to reduce NOx emissions by 10%-50%, then emission reduction is achieved, but corrosion and bacterial growth in storage reservoirs increases

Engineering Contradiction:
ImproveNOx emission reductionVSAvoidcorrosion and bacterial growth
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent introduces modified bio-carbon as an intermediary substance that mediates between water and the fuel system. Its porous structure and high surface area allow it to stabilize water droplets, enabling NOx reduction while the bio-carbon itself acts as a barrier to corrosion and bacterial growth in storage reservoirs.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs modified bio-carbon, which can be derived from inexpensive agricultural waste, as a disposable additive that performs its function during combustion and then decomposes harmlessly, avoiding the need for expensive corrosion protection systems while enabling safe storage of water-containing fuel mixes.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Object-generated harmful factors

If water droplets are added to gasoline to reduce particulate emission by 20%-60%, then emission reduction is achieved, but ice crystal formation in cold weather causing frosting and blockage increases

Engineering Contradiction:
Improveparticulate emission reductionVSAvoidice crystal formation and blockage
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the physical parameters of water in the fuel system by incorporating it into a microemulsion stabilized by modified bio-carbon and surfactants. This changes the freezing behavior of water from forming large ice crystals to creating a stable emulsion that remains fluid at lower temperatures, reducing frosting and blockage while maintaining particulate emission reduction.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If large quantities of expensive emulsifying surfactants are used to achieve high water content microemulsion stability, then short term stability is improved, but cost increases making commercial applications unsuitable

Engineering Contradiction:
Improvemicroemulsion stabilityVSAvoidcommercial viability
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent replaces expensive synthetic surfactants with modified bio-carbon derived from inexpensive agricultural waste. The bio-carbon's porous structure and high surface area provide the necessary stabilization function at much lower cost, making commercial application viable while maintaining microemulsion stability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the cost parameter by using modified bio-carbon instead of conventional surfactants. The bio-carbon can be produced from low-cost feedstocks like agricultural waste, significantly reducing the cost of high water content microemulsions while maintaining stability, thereby enabling commercial viability.
