Vehicle Fuel Tank Static Eliminator for Viscosity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity in vehicles affects the viscosity of lubricating oil or fuel, leading to deteriorated engine operating responses due to increased viscosity, and existing methods do not adequately address the specific effects and elimination of this static electricity.
Innovation Solution
A self-discharge type static eliminator is placed on the outside surface of the tank's bottom wall, which discharges positive charges into the air, effectively reducing static electricity in the lubricating oil or fuel flowing into the strainer, thereby lowering viscosity and improving engine response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle carries static electricity, then the lubricating oil or fuel is stored in the tank, but the viscosity of the lubricating oil or fuel rises and affects the operating response of the engine
Solution Approach 1:
A self-discharge type static eliminator is introduced as an intermediary device between the charged tank and the lubricating oil/fuel system. The static eliminator discharge electrode discharges positive charges to the air, eliminating static electricity from the lubricating oil or fuel before it reaches the strainer and engine, thereby resolving the viscosity increase problem without affecting the fuel storage function
Solution Approach 2:
The patent replaces mechanical or chemical methods of viscosity control with an electrical field-based approach. By using electrostatic discharge to eliminate static electricity, the system avoids mechanical agitation or chemical additives that could alter fuel properties, directly addressing the root cause of viscosity increase
2Reliability
If a self-discharge type static eliminator is placed on the tank bottom wall, then static electricity is eliminated from the lubricating oil or fuel, but the device complexity increases
Solution Approach 1:
The self-discharge type static eliminator is designed to operate autonomously without external power supply or control systems. The discharge electrode automatically discharges positive charges to the air based on the electrostatic potential difference, eliminating the need for complex control circuits, power sources, or monitoring systems while maintaining effective static electricity elimination
Solution Approach 2:
The static eliminator is positioned on the outside surface of the tank bottom wall, extracting the static electricity elimination function from the internal fuel system. This external placement simplifies the overall system structure by separating the static elimination function from the fuel storage and delivery components, avoiding interference with the strainer and pump operations

AI summary
In a tank which stores lubricating oil or fuel therein, a strainer for lubricating oil or fuel is arranged at the bottom portion of the inside of the tank. The tank and the lubricating oil or fuel which is stored in the tank carry a positive charge. A self-discharge type static eliminator is placed on the outer surface of the bottom floor of the tank which corresponds to the back side of the inside surface of the tank which faces the strainer to thereby eliminate static electricity from the lubricating oil or fuel which flows into the strainer by the self-discharge type static eliminator.
