Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If catalytic converters are used to reduce emissions, then nitrogen oxide emissions are reduced, but the cost increases and the device becomes prone to damage
Solution Approach 1:
The patent recirculates combustion fumes containing nitrogen oxides back into the combustion chamber where they are converted into useful components of the combustion process. The harmful nitrogen oxides are transformed into nitrogen and oxygen through further combustion, eliminating the need for catalytic converters while maintaining emission reduction
Solution Approach 2:
The patent extracts the harmful combustion fumes from the exhaust stream and redirects them back into the combustion chamber through a recirculation duct, separating the harmful components from the final exhaust emission
