Modular Fuel Supply Element With Integrated Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel supply systems for internal combustion piston engines lack serviceability and flexibility, particularly in the removal and maintenance of fuel admission valves, which are often complex and require separate handling.
Innovation Solution
A fuel supply element with a T-shaped design featuring a bottom portion attached to the cylinder head and a top portion with fastening parts, where the fuel admission valve is integrated and removable as a single unit, allowing for improved serviceability and leak detection through fluid gaps, and a double-walled configuration for enhanced sealing and detection of leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fuel admission valve is fixed separately to the cylinder head surface, then the valve can be positioned correctly, but the serviceability and ease of removal are poor requiring separate handling
Solution Approach 1:
The patent combines the fuel admission valve element with the fuel supply element into a single integrated unit. The valve element is attached to the bottom portion of the fuel supply element, creating a unified component that can be installed and removed together, eliminating the need for separate handling of the valve during maintenance operations.
Solution Approach 2:
The fuel supply system is divided into modular components: the fuel supply element with integrated valve, intermediate channel portions, and top portions. This segmentation allows the valve-containing unit to be easily detached and replaced as a single module, improving serviceability while maintaining functional integrity.
2Ease of repair
If the fuel supply system uses separate components for fuel supply and valve control, then each component can be optimized independently, but the overall system requires more parts and is harder to maintain
Solution Approach 1:
The fuel admission valve element is integrated with the fuel supply element, reducing the total number of separate parts. This merging maintains the ability to optimize each functional aspect while eliminating the need for multiple discrete components that would require separate maintenance procedures.
3Ease of operation
If the fuel supply element is designed as a single integrated unit, then serviceability is improved, but the manufacturing complexity increases
Solution Approach 1:
The fuel supply element is designed with a bottom portion and a top portion that can be manufactured separately and then assembled. The valve element is attached to the bottom portion, which can be produced as a modular unit. This segmentation allows each component to be manufactured using optimized processes before final assembly, reducing overall manufacturing complexity while maintaining the integrated design benefits.
