Flexible Fuel Sensor Housing with Bypass Passageway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible fuel vehicle systems face limitations in fuel volume flow due to tubing routing, which restricts fuel volume delivery to internal combustion engines during high-performance requirements, necessitating additional tubing that complicates the system.
Innovation Solution
A housing for a flexible fuel sensor with a first and second chamber and a bypass passageway allowing fuel to flow through and around the sensor, enabling larger volumes of fuel to pass through without additional tubing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fuel flows through the flexible fuel sensor via tubing, then the sensor can measure the ethanol-gasoline ratio, but the fuel volume flow is limited
Solution Approach 1:
The housing is divided into a first chamber and a second chamber, creating separate flow paths. The first chamber receives fuel through an inlet and directs it through the flexible fuel sensor, while the second chamber receives fuel through a bypass passageway that flows around the sensor. This segmentation allows simultaneous measurement and high-volume fuel delivery through parallel pathways.
Solution Approach 2:
The invention transitions from a single-dimensional linear flow through tubing to a two-dimensional parallel flow structure. By creating multiple chambers and passageways that operate simultaneously in parallel, the system increases fuel volume capacity while maintaining the measurement function, effectively adding a spatial dimension to the flow architecture.
2Quantity of substance
If additional tubing is used to bypass fuel around the sensor, then fuel volume flow increases, but the system becomes more complex
Solution Approach 1:
The invention merges the measurement function and the bypass function into a single integrated housing structure. The first chamber contains the sensor and its associated tubing, while the second chamber provides the bypass path, and both are combined within one housing that receives a single fuel source. This eliminates the need for separate external tubing to connect multiple components, reducing overall system complexity while maintaining high fuel volume flow capability.
Solution Approach 2:
The housing serves multiple functions simultaneously: it contains the flexible fuel sensor, provides fuel delivery pathways for both measurement and bypass, and manages the ethanol-gasoline ratio monitoring. By making the housing a multi-functional component that integrates several previously separate elements, the system achieves high fuel volume flow without proportionally increasing complexity.
