Problem Statement
- Existing internal combustion engine systems fail to optimize both fuel consumption and emissions simultaneously.
- Current solutions focus either on fuel efficiency or emissions control, lacking a comprehensive approach.
- There is a need for a reliable dual fuel system and method that addresses both performance enhancement and environmental impact.
Technology
- The invention introduces a dual fuel system for internal combustion engines, combining a gaseous fuel delivery unit, an open Electronic Control Unit (ECU), and an eddy current dynamometer to optimize fuel consumption and reduce emissions.
- The system uses real-time engine parameters to precisely control and adjust fuel delivery, ensuring an optimal air-fuel mixture and improved combustion efficiency.
- Key components include mass flow controllers, a buffer chamber, air and gas filters, a mixing chamber, exhaust gas recirculation, and advanced pressure regulation mechanisms, all managed by a central controller for dynamic adjustments based on engine load.
