Polyether Cleaning Composition for Engine Deposit Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions for internal combustion engines are not highly effective in removing carbonaceous deposits from fuel delivery systems, air intake systems, and combustion chambers, often requiring specialized equipment and taking a long time to achieve results.
Innovation Solution
A single-phase cleaning composition comprising a polyether component, polar and non-polar solvents, and optional additives like detergents and corrosion inhibitors, which can be introduced directly to the fuel system or air intake port, effectively removing deposits from fuel injectors, air intake valves, piston tops, and cylinder heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cleaning compositions are used to remove carbonaceous deposits, then deposits can be removed from fuel delivery systems, air intake systems, and combustion chambers, but the cleaning process takes a long time to achieve results
Solution Approach 1:
The patent modifies the chemical composition parameters by incorporating specific solvents (aromatic hydrocarbons, aliphatic hydrocarbons, esters, ketones, alcohols) and surfactants in optimized ratios to enhance cleaning speed and effectiveness, directly resolving the contradiction between thorough deposit removal and extended cleaning time
Solution Approach 2:
The cleaning composition uses a composite formulation combining multiple solvent types, surfactants, and optional additives (corrosion inhibitors, lubricity enhancers) to create a synergistic effect that accelerates deposit removal while maintaining system protection, thereby reducing cleaning time without sacrificing reliability
2Reliability
If existing cleaning compositions are used, then deposits can be removed, but specialized equipment is required and the method is not easily performed without service garage equipment
Solution Approach 1:
The cleaning composition is designed as a self-contained fuel additive that can be easily poured into the fuel tank without requiring specialized equipment or service garage facilities, enabling consumers to perform the cleaning operation themselves while maintaining effective deposit removal capability
Solution Approach 2:
The composition serves multiple functions simultaneously: it cleans deposits from fuel delivery systems, air intake systems, and combustion chambers, while also protecting against corrosion and enhancing lubricity, all through a single additive application that requires no specialized equipment
3Ease of operation
If fuel additive composition is added to the fuel tank, then the additive is delivered by the fuel to the engine, but significant deposits may take some time to achieve results
Solution Approach 1:
The patent enhances the cleaning kinetics by optimizing the concentration and type of solvents and surfactants in the composition, enabling faster breakdown and removal of carbonaceous deposits while the additive is delivered through the fuel system, thereby reducing the time delay between application and visible results
