1Object-generated harmful factors
If conventional combustion engines use traditional fossil fuels, then engine performance and power output are maintained, but harmful emissions (NOx, CO2, SOx) increase and fuel costs rise
Solution Approach 1:
The system changes fuel parameters by blending low cetane fuels (ethanol, methanol, propane) with conventional diesel fuels in controlled ratios. The controller adjusts fuel injection timing, duration, and quantity based on engine operating conditions to optimize combustion parameters, reducing NOx emissions while maintaining engine performance and fuel efficiency.
Solution Approach 2:
The invention uses composite fuel blends combining multiple fuel types (low cetane fuels and conventional fuels) in specific proportions. This composite approach allows the system to leverage the low emission characteristics of low cetane fuels while maintaining the energy density and combustion reliability of conventional fuels, achieving both emission reduction and fuel efficiency.
2Adaptability or versatility
If multiple fuel types are blended and injected, then emissions are reduced and fuel flexibility improves, but system complexity and control requirements increase
Solution Approach 1:
The controller continuously monitors engine operating parameters (temperature, pressure, load, exhaust gas composition) and adjusts fuel injection strategies in real-time based on feedback. This closed-loop control enables the system to automatically optimize fuel blending ratios and injection timing to reduce emissions while adapting to varying operating conditions, managing complexity through intelligent control.
Solution Approach 2:
The system dynamically adjusts fuel delivery parameters including injection timing, duration, and quantity based on real-time engine conditions. The controller can switch between different fuel types and blending ratios depending on operating requirements, enabling flexible adaptation to various scenarios while managing system complexity through dynamic rather than static control.
