Pre-Tank Fuel Filter for Particulate Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gasoline fueled vehicles are prone to fuel system failures due to particulates and impurities entering the fuel system, leading to inefficient performance, premature component wear, and costly repairs, with existing filtration systems requiring mechanical maintenance and being ineffective in preventing particulate entry.
Innovation Solution
A pre-tank fuel filtration system using a fine micron filter inserted into the fuel inlet of a vehicle's fuel tank to screen out particulates and impurities before they enter the fuel system, designed to meet or exceed manufacturer and regulatory specifications, with a removable and easy-to-install filter that extends the life of the fuel system components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-line fuel filtering is used within a vehicle, then particulates are filtered before reaching sensitive components, but the system requires mechanical maintenance and significant time and cost for consumers and fleet managers
Solution Approach 1:
The patent applies preliminary action by installing a fuel filter at the fuel inlet (pre-tank) position, filtering particulates before they enter the fuel tank and subsequent fuel system components. This proactive filtration approach prevents particulate accumulation in the fuel system, eliminating the need for complex in-line filters and reducing maintenance requirements while improving fuel system reliability
2Object-affected harmful factors
If existing in-line fuel filtering systems are used, then some particulate protection is provided, but the systems are not effective in preventing particulates from entering the fuel system and require significant maintenance
Solution Approach 1:
The patent extracts the fuel filtration function from the traditional in-line filter location and relocates it to the fuel inlet position. This separation allows the filter to be positioned where it can prevent particulate entry more effectively, while also being easily removable for maintenance without affecting the rest of the fuel system
Solution Approach 2:
The patent employs a simple, inexpensive mesh filter that can be easily replaced. The filter element is designed as a disposable or easily replaceable component made from affordable materials like mesh screen, eliminating the need for complex maintenance procedures associated with traditional in-line fuel filters
3Reliability
If fine micron filtration is implemented at the fuel inlet, then particulates are prevented from entering the fuel system, but the filter may require periodic replacement or cleaning
Solution Approach 1:
The patent utilizes porous mesh material for the filter element, which provides effective fine micron filtration while maintaining open structure that prevents clogging. The porous mesh allows fuel to pass through while trapping particulates, and its open structure enables easy cleaning or replacement without complex disassembly
Solution Approach 2:
The patent segments the fuel filtration function into a separate, standalone filter element that is independent from the fuel tank and fuel system components. This modular design allows the filter to be easily removed, replaced, or cleaned without affecting the rest of the fuel system, reducing overall system complexity
