Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If methanol and gasoline are mixed without heating and stirring, then the fuel system structure remains simple, but the mixing is uneven leading to insufficient combustion
Solution Approach 1:
The patent applies preliminary action by heating and stirring the methanol and gasoline mixture before injection into the engine. The microwave heating device and stirring device are activated in advance to ensure uniform mixing and appropriate temperature before the fuel enters the combustion chamber, thereby improving combustion sufficiency without requiring complex real-time adjustments during operation.
Solution Approach 2:
The patent replaces traditional mechanical heating systems with microwave heating technology. The microwave heating device uses electromagnetic radiation to directly heat the fuel molecules, achieving rapid and uniform heating without the need for complex mechanical heat exchangers or thermal conduction systems, thus improving combustion while maintaining relatively simple system structure.
2Reliability
If ECU adjusts injection volume in real-time, then fuel combustion can be optimized, but information feedback lag occurs resulting in insufficient cylinder combustion
Solution Approach 1:
The patent eliminates feedback lag by performing the mixing and heating actions in advance before the fuel enters the cylinder. The microwave heating and stirring occur continuously or periodically before injection, ensuring the fuel is always in optimal condition without waiting for ECU feedback loops, thereby resolving the time delay problem inherent in electronic control systems.
3Stability of the object's composition
If methanol and gasoline are blended before filling with mutual solvent and stabilizer, then the mixed fuel stability is improved, but the filling process complexity and fuel cost increase significantly
Solution Approach 1:
The patent extracts and eliminates the need for mutual solvents and stabilizers by using microwave heating and stirring to achieve stable mixing. The electromagnetic energy directly作用于 the fuel molecules to create uniform mixing without requiring additional chemical additives, thereby maintaining fuel stability while simplifying the blending process and reducing costs.
Solution Approach 2:
The patent replaces chemical stabilization methods (using solvents and stabilizers) with physical methods (microwave heating and stirring). This substitution achieves stable fuel mixing through thermal and mechanical energy rather than chemical additives, eliminating the need for complex blending processes and reducing fuel costs.
4Temperature
If traditional heating methods are used for methanol and gasoline, then the fuel can be heated, but heat waste occurs and heating is not uniform
Solution Approach 1:
The patent replaces traditional conductive or convective heating methods with microwave heating technology. The microwave heating device uses electromagnetic radiation to directly excite fuel molecules, generating heat internally throughout the entire fuel volume simultaneously. This achieves uniform heating without heat loss to surrounding components, as the energy is absorbed directly by the fuel rather than being transferred through thermal conduction from external sources.
