Supplemental Fuel Mixing for Universal Diesel Engine Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conversion kits for diesel engines to use supplemental fuels like natural gas are engine-specific, making them complex to install, difficult to tune, and potentially damaging due to unfamiliarity with specific designs, limiting their versatility and usability.
Innovation Solution
A universal supplemental fuel system for compression-ignition engines that includes a fuel mixer with a Venturi nozzle, positioned within the air supply system, which generates a vacuum signal to draw supplemental fuel into the engine's combustion chamber, mixing it with primary fuel, allowing for efficient and flexible use of gaseous fuels across various engine types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engine-specific conversion kits are used, then the kit can be designed to match a specific engine, but the complexity of installation and tuning increases due to lack of familiarity with specific designs
Solution Approach 1:
The patent applies universality by designing a conversion kit with a universal adapter assembly that can be adapted to multiple different engine types and configurations. The adapter assembly includes standardized components that can interface with various engine models, eliminating the need for completely different kits for each engine type while maintaining proper fuel delivery and mixing ratios.
2Adaptability or versatility
If universal supplemental fuel system is implemented, then adaptability to different engine types improves, but manufacturing precision requirements increase to ensure proper mixing ratios
Solution Approach 1:
The patent incorporates feedback mechanisms through sensors that monitor fuel flow rates, air flow rates, and mixing ratios in real-time. The system uses this feedback data to automatically adjust the fuel delivery and mixing processes, ensuring precise fuel-air ratios are maintained across different engine types without requiring complex manual calibration for each application.
3Device complexity
If supplemental fuel is drawn via vacuum signal, then the system simplifies fuel delivery mechanism, but the fuel delivery becomes dependent on engine operating conditions
Solution Approach 1:
The patent applies self-service by designing a fuel delivery system that automatically regulates its own operation based on engine conditions. The vacuum signal from the engine intake manifold automatically controls the fuel flow rate, and the system includes self-adjusting mechanisms that maintain proper fuel delivery across varying engine speeds and loads without requiring external intervention or complex control systems.

Function Achieved in This Case
The system reduces primary fuel consumption, lowers fuel costs, improves engine performance, and simplifies installation by providing a universal solution compatible with multiple engine designs, eliminating the need for engine-specific conversion kits.
Implementation Method 1
The nozzle passage is configured to receive air flowing through the conduit and generate a vacuum signal at the second inlet as the air flowing through the conduit flows through the nozzle passage

AI summary
A supplemental fuel system includes a supplemental fuel tank, an electronic valve, a voltage sensor, and a controller. The supplemental fuel tank is configured to store a supplemental fuel configured to supplement a primary fuel used by an engine. The electronic valve is configured to be positioned between the supplemental fuel tank and an air supply system for the engine. The voltage sensor is configured to acquire voltage data from a power supply indicative of a voltage of the power supply. The power supply is configured to receive power from an alternator driven by the engine. The controller is configured to control the electronic valve such that the electronic valve is (i) closed in response to the voltage being less than a voltage threshold and (ii) open or openable in response to the voltage being greater than the voltage threshold.
