Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal combustion engine exhaust systems fail to effectively prevent gases and unconsumed fluids from exiting, resulting in unmodified exhaust emissions.
Innovation Solution
An exhaust modification system with a housing and an impeller that accelerates particulate matter and liquid droplets, followed by a filter subassembly to collect and remove these components, with the option of cooling the filter to enhance adhesion and filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional exhaust system is used, then the system structure is simple, but the exhaust emissions contain harmful particulate matter and liquid droplets that are not removed
Solution Approach 1:
The exhaust system is divided into distinct functional segments: an impeller section for centrifugal separation and a filter subassembly for filtration. This segmentation allows each component to specialize in removing specific contaminants, improving overall effectiveness while maintaining manageable system complexity
Solution Approach 2:
The impeller acts as an intermediary mechanism between the exhaust source and the filter subassembly. It pre-separates particulate matter and liquid droplets through centrifugal force, reducing the load on the filter and improving the efficiency of the entire exhaust modification system
2Reliability
If the filter subassembly is cooled, then the adhesion of particulate matter and liquid droplets to filter elements is improved, but the system requires additional cooling air supply
Solution Approach 1:
The system utilizes available cooler air from the automobile's air conditioning unit to cool the filter subassembly. This self-service approach leverages existing vehicle resources rather than requiring a separate cooling system, improving filtration efficiency while avoiding additional complexity
Solution Approach 2:
The air conditioning unit serves multiple functions: it provides climate control for the vehicle interior and simultaneously cools the exhaust filter subassembly to enhance particulate matter adhesion. This multi-functionality eliminates the need for dedicated cooling infrastructure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system transforms exhaust emissions into modified emissions by removing particulate matter and liquid droplets, improving exhaust quality by reducing harmful components and allowing primarily gases to exit.
Implementation Method 1
The impeller is rotatable about an axis thereof that is coaxial with the housing axis, for accelerating particulate matter and liquid droplets in the exhaust emissions moving past the impeller outwardly from the axis
Implementation Method 2
The filter subassembly is configured to collect at least part of the particulate matter and the liquid droplets in the exhaust emissions, for removing the part of the particulate matter and the liquid droplets from the exhaust emissions
Implementation Method 3
When the filter elements are at a temperature that is lower than the temperature of the exhaust emissions, more of the particulate matter and the liquid droplets in the exhaust emissions adhere to the filter elements

AI summary
An internal combustion engine exhaust modification system for transforming exhaust emissions from an internal combustion engine into modified exhaust emissions. The exhaust modification system include a housing extending between inlet and outlet ends thereof. The housing has a first cross-sectional area at a first location that is downstream from the inlet end and a second cross-sectional area at a second location that is downstream from the first location. The second cross-sectional area is larger than the first cross-sectional area. The system also includes an impeller rotatably mounted in the housing, and a filter subassembly. The filter subassembly removes part of particulate matter and liquid droplets in the exhaust emissions to transform the exhaust emissions into modified exhaust emissions.
