Layton, Utah Patent of the Year – 2024/2025
American CNG LLC has been awarded the 2024/2025 Patent of the Year for its innovative approach to enhancing diesel engine efficiency. Their invention, detailed in U.S. Patent No. 11952969, titled ‘Supplemental fuel system for compression-ignition engine’, introduces a system that integrates supplemental fuels like compressed natural gas (CNG) into diesel engines, aiming to reduce emissions and improve performance.
American CNG’s system features a fuel mixer with a nozzle and stem designed to introduce supplemental fuel into the engine’s air intake. The nozzle is positioned within the air conduit, allowing a portion of the intake air to mix with the supplemental fuel, while the remaining air flows around the nozzle. This design ensures a balanced air-fuel mixture, optimizing combustion efficiency.
The stem extends through the conduit wall, connecting the supplemental fuel source to the nozzle. This configuration allows for precise control of fuel delivery, enhancing engine responsiveness and reducing fuel consumption. The system’s design also facilitates easy integration into existing engine architectures without significant modifications.
By enabling diesel engines to utilize cleaner-burning supplemental fuels, this innovation addresses environmental concerns associated with traditional diesel combustion. It offers a practical solution for industries seeking to reduce their carbon footprint while maintaining engine performance. American CNG’s invention represents a significant step toward more sustainable and efficient heavy-duty transportation solutions.
