Dual Fuel Engine Control Assembly Simplifying Valve and Choke Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual fuel internal combustion engines have complex and inefficient operations for fuel selection, choke adjustment, and flameout control, leading to potential risks such as fuel leaks and engine damage due to independent control of fuel valves and choke systems.
Innovation Solution
A combination control assembly with a dial and turntable system that simplifies the operation by rotating the dial to control both fuel valves and the choke simultaneously, using a disk body, shift lever, and rotating parts to manage fuel flow and air intake, while an indicator panel and biasing spring ensure safe engine shutdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fuel valves and choke systems are controlled independently, then each component can be adjusted separately, but the operation becomes complex and increases the risk of fuel leaks and engine damage
Solution Approach 1:
The patent combines multiple independent control functions (fuel valve control and choke adjustment) into a single integrated control assembly. The control assembly includes a first control component for fuel valves and a second control component for choke, both integrated into one unit that simplifies user operation while maintaining functional separation for safety
Solution Approach 2:
The control assembly serves multiple functions simultaneously - it controls both the fuel valves and the choke system through a unified interface. This multi-functional design allows a single control mechanism to manage different aspects of fuel delivery and air intake, reducing operational complexity
2Ease of operation
If multiple control components are integrated into one assembly, then operation is simplified, but the device structure becomes more complex
Solution Approach 1:
The control assembly is segmented into distinct functional components - a first control component for fuel valves and a second control component for choke - that are integrated but remain functionally separate. This segmentation allows for simplified operation while managing structural complexity through modular design
3Reliability
If fuel valves are not properly controlled, then operation is simpler, but fuel leaks and fire hazards increase
Solution Approach 1:
The control assembly incorporates preliminary safety measures by designing the fuel valve control to prevent improper operation before hazards can occur. The integrated design ensures that fuel valves are properly controlled during normal operation and can be quickly shut off in emergency situations, preventing fuel leaks and fire hazards
