Fuel Vapor Processor Regulator for Stable Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel vapor processors lack a regulator to control the volume of fuel vapor containing gas supplied to the separation membrane, leading to inconsistent fuel vapor concentration and potential air pollution when large volumes of fuel vapor are processed, causing fuel vapor to escape into the atmosphere and disrupting the fuel-air ratio in engines.
Innovation Solution
Incorporating a regulator to control the volume of fuel vapor containing gas supplied to the separator, which stabilizes the separation ability and maintains a predetermined fuel vapor density in the diluted gas, preventing excessive fuel vapor from accumulating near the air communicating port and ensuring constant fuel vapor density when introduced into the canister or released into the atmosphere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the volume of fuel vapor containing gas supplied to the separation membrane increases, then the productivity of fuel vapor processing increases, but the separation performance deteriorates and fuel vapor concentration becomes inconsistent
Solution Approach 1:
The patent introduces a regulator to control and adjust the flow rate parameters of fuel vapor containing gas supplied to the separation membrane. By dynamically adjusting the flow rate parameter within an optimal range, the system maintains consistent separation performance while accommodating varying fuel vapor generation conditions, thus resolving the contradiction between processing volume and concentration consistency.
2Device complexity
If no regulator is provided to control the gas volume supplied to the separator, then the device complexity is reduced, but the reliability of separation performance deteriorates
Solution Approach 1:
The regulator acts as an intermediary device between the fuel tank and the separation membrane. It mediates the flow of fuel vapor containing gas, ensuring that the volume supplied to the separator remains within the optimal range for consistent separation performance. This intermediary component enhances reliability without significantly complicating the overall system structure.
3Productivity
If large volume of fuel vapor is supplied to the separation membrane, then the productivity increases, but harmful factors increase as fuel vapor escapes into the atmosphere
Solution Approach 1:
The system employs feedback control where the regulator adjusts the flow rate of fuel vapor containing gas based on the separation membrane's performance characteristics. This feedback mechanism ensures that the supplied gas volume remains within the optimal separation range, preventing excessive fuel vapor from bypassing the separator and escaping into the atmosphere, thus maintaining high productivity while eliminating harmful emissions.

AI summary
A fuel vapor processor has a fuel tank configured to reserve fuel, a canister containing adsorbent capable of adsorbing fuel vapor vaporized in the fuel tank, a separator receiving a fuel vapor containing gas from the fuel tank, a regulator controlling the volume of the fuel vapor containing gas supplied to the separator, and a suction unit capable of removing the fuel vapor from the canister. The separator selectively passes the fuel vapor therethrough in order to divide the fuel vapor containing gas into a first gas mainly containing the fuel vapor and a second gas having a fuel vapor density lower than the first gas. The suction unit suctions the first gas from the separator in order to return the first gas into the fuel tank. The second gas is introduced into the canister or is released into the atmosphere.
